⚠️ List of breaking changes can be found here.
Features
-
eef1afe (linegauge) Allow LineGauge background styles by @nowNick in #565
This PR deprecates `gauge_style` in favor of `filled_style` and `unfilled_style` which can have it's foreground and background styled. `cargo run --example=line_gauge --features=crossterm`
https://github.com/ratatui-org/ratatui/assets/5149215/5fb2ce65-8607-478f-8be4-092e08612f5b
Implements:https://github.com/ratatui-org/ratatui/issues/424
-
1365620 (borders) Add FULL and EMPTY border sets by @joshka in #1182
border::FULL
uses a full block symbol, whileborder::EMPTY
uses an empty space. This is useful for when you need to allocate space for the border and apply the border style to a block without actually drawing a border. This makes it possible to style the entire title area or a block rather than just the title content.
use ratatui::{symbols::border, widgets::Block};
let block = Block::bordered().title("Title").border_set(border::FULL);
let block = Block::bordered().title("Title").border_set(border::EMPTY);
-
7a48c5b (cell) Add EMPTY and (const) new method by @EdJoPaTo in #1143
This simplifies calls to `Buffer::filled` in tests.
-
3f2f2cd (docs) Add tracing example by @joshka in #1192
Add an example that demonstrates logging to a file for:
https://forum.ratatui.rs/t/how-do-you-println-debug-your-tui-programs/66
cargo run --example tracing
RUST_LOG=trace cargo run --example=tracing
cat tracing.log
-
1520ed9 (layout) Impl Display for Position and Size by @joshka in #1162
-
46977d8 (list) Add list navigation methods (first, last, previous, next) by @joshka in #1159 [breaking]
Also cleans up the list example significantly (see also <https://github.com/ratatui-org/ratatui/issues/1157>)
Fixes:https://github.com/ratatui-org/ratatui/pull/1159
BREAKING CHANGE:The
List
widget now clamps the selected index to the bounds of the list when navigating withfirst
,last
,previous
, andnext
, as well as when setting the index directly withselect
. -
10d7788 (style) Add conversions from the palette crate colors by @joshka in #1172
This is behind the "palette" feature flag. ```rust use palette::{LinSrgb, Srgb}; use ratatui::style::Color; let color = Color::from(Srgb::new(1.0f32, 0.0, 0.0)); let color = Color::from(LinSrgb::new(1.0f32, 0.0, 0.0)); ```
-
7ef2dae (text) support conversion from Display to Span, Line and Text by @orhun in #1167
Now you can create `Line` and `Text` from numbers like so: ```rust let line = 42.to_line(); let text = 666.to_text(); ```
-
74a32af (uncategorized) Re-export backends from the ratatui crate by @joshka in #1151
`crossterm`, `termion`, and `termwiz` can now be accessed as `ratatui::{crossterm, termion, termwiz}` respectively. This makes it possible to just add the Ratatui crate as a dependency and use the backend of choice without having to add the backend crates as dependencies. To update existing code, replace all instances of `crossterm::` with `ratatui::crossterm::`, `termion::` with `ratatui::termion::`, and `termwiz::` with `ratatui::termwiz::`.
-
3594180 (uncategorized) Make Stylize's
.bg(color)
generic by @kdheepak in #1103 [breaking] -
0b5fd6b (uncategorized) Add writer() and writer_mut() to termion and crossterm backends by @enricozb in #991
It is sometimes useful to obtain access to the writer if we want to see what has been written so far. For example, when using &mut [u8] as a writer.
Bug Fixes
-
efa965e (line) Remove newlines when converting strings to Lines by @joshka in #1191
Line::from("a\nb")
now returns a line with twoSpan
s instead of 1 -
d370aa7 (span) Ensure that zero-width characters are rendered correctly by @joshka in #1165
-
127d706 (table) Ensure render offset without selection properly by @joshka in #1187
-
4bfdc15 (uncategorized) Render of &str and String doesn't respect area.width by @thscharler in #1177
-
e6871b9 (uncategorized) Avoid unicode-width breaking change in tests by @joshka in #1171
unicode-width 0.1.13 changed the width of \u{1} from 0 to 1. Our tests assumed that \u{1} had a width of 0, so this change replaces the \u{1} character with \u{200B} (zero width space) in the tests. Upstream issue (closed as won't fix): https://github.com/unicode-rs/unicode-width/issues/55
-
7f3efb0 (uncategorized) Pin unicode-width crate to 0.1.13 by @joshka in #1170
semver breaking change in 0.1.13 <https://github.com/unicode-rs/unicode-width/issues/55> <!-- Please read CONTRIBUTING.md before submitting any pull request. -->

Refactor
-
73fd367 (block) Group builder pattern methods by @EdJoPaTo in #1134
-
257db62 (cell) Must_use and simplify style() by @EdJoPaTo in #1124
<!-- Please read CONTRIBUTING.md before submitting any pull request. -->
-
bf20369 (cell) Reset instead of applying default by @EdJoPaTo in #1127
Using reset is clearer to me what actually happens. On the other case a struct is created to override the old one completely which basically does the same in a less clear way.
-
cf67ed9 (lint) Use clippy::or_fun_call by @EdJoPaTo in #1138
https://rust-lang.github.io/rust-clippy/master/index.html#or_fun_call
-
4770e71 (list) Remove deprecated
start_corner
andCorner
by @Valentin271 in #759 [breaking]List::start_corner
was deprecated in v0.25. UseList::direction
andListDirection
instead.
- list.start_corner(Corner::TopLeft);
- list.start_corner(Corner::TopRight);
// This is not an error, BottomRight rendered top to bottom previously
- list.start_corner(Corner::BottomRight);
// all becomes
+ list.direction(ListDirection::TopToBottom);
- list.start_corner(Corner::BottomLeft);
// becomes
+ list.direction(ListDirection::BottomToTop);
layout::Corner
is removed entirely.
-
4f77910 (padding) Add Padding::ZERO as a constant by @EdJoPaTo in #1133
Deprecate Padding::zero()
-
8061813 (uncategorized) Expand glob imports by @joshka in #1152
Consensus is that explicit imports make it easier to understand the example code. This commit removes the prelude import from all examples and replaces it with the necessary imports, and expands other glob imports (widget::*, Constraint::*, KeyCode::*, etc.) everywhere else. Prelude glob imports not in examples are not covered by this PR. See https://github.com/ratatui-org/ratatui/issues/1150 for more details.
-
d929971 (uncategorized) Dont manually impl Default for defaults by @EdJoPaTo in #1142
Replace `impl Default` by `#[derive(Default)]` when its implementation equals.
-
8a60a56 (uncategorized) Needless_pass_by_ref_mut by @EdJoPaTo in #1137
https://rust-lang.github.io/rust-clippy/master/index.html#needless_pass_by_ref_mut
-
1de9a82 (uncategorized) Simplify if let by @EdJoPaTo in #1135
While looking through lints [`clippy::option_if_let_else`](https://rust-lang.github.io/rust-clippy/master/index.html#option_if_let_else) found these. Other findings are more complex so I skipped them.

4f307e6 (examples) Simplify paragraph example by @joshka in #1169
-
f429f68 (examples) Remove lifetimes from the List example by @matta in #1132
Simplify the List example by removing lifetimes not strictly necessary to demonstrate how Ratatui lists work. Instead, the sample strings are copied into each `TodoItem`. To further simplify, I changed the code to use a new TodoItem::new function, rather than an implementation of the `From` trait.
-
2f8a936 (uncategorized) Fix links on docs.rs by @EdJoPaTo in #1144
This also results in a more readable Cargo.toml as the locations of the things are more obvious now. Includes rewording of the underline-color feature. Logs of the errors: https://docs.rs/crate/ratatui/0.26.3/builds/1224962 Also see #989

Miscellaneous Tasks
-
7b45f74 (prelude) Add / remove items by @joshka in #1149 [breaking]
his PR removes the items from the prelude that don't form a coherent common vocabulary and adds the missing items that do. Based on a comment at <https://www.reddit.com/r/rust/comments/1cle18j/comment/l2uuuh7/>
BREAKING CHANGE:The following items have been removed from the prelude:
-
style::Styled
- this trait is useful for widgets that want to support the Stylize trait, but it adds complexity as widgets have twostyle
methods and aset_style
method. -
symbols::Marker
- this item is used by code that needs to draw to theCanvas
widget, but it's not a common item that would be used by most users of the library. -
terminal::{CompletedFrame, TerminalOptions, Viewport}
- these items are rarely used by code that needs to interact with the terminal, and they're generally only ever used once in any app.
The following items have been added to the prelude:
-
layout::{Position, Size}
- these items are used by code that needs to interact with the layout system. These are newer items that were added in the last few releases, which should be used more liberally. -
cd64367 (symbols) Add tests for line symbols by @joshka in #1186
-
8cfc316 (uncategorized) Alphabetize examples in Cargo.toml by @joshka in #1145
Build
-
70df102 (bench) Improve benchmark consistency by @EdJoPaTo in #1126
Codegen units are optimized on their own. Per default bench / release have 16 codegen units. What ends up in a codeget unit is rather random and can influence a benchmark result as a code change can move stuff into a different codegen unit → prevent / allow LLVM optimizations unrelated to the actual change.

We are happy to announce a brand new Ratatui Forum 🐭 for Rust & TUI enthusiasts.
This is a patch release that fixes the unicode truncation bug, adds performance and quality of life improvements.
✨ Release highlights: https://ratatui.rs/highlights/v0263/
Features
-
97ee102 (buffer) Track_caller for index_of by @EdJoPaTo in #1046 **
The caller put in the wrong x/y -> the caller is the cause.
-
bf09234 (table) Make TableState::new const by @EdJoPaTo in #1040
-
eb281df (uncategorized) Use inner Display implementation by @EdJoPaTo in #1097
-
ec763af (uncategorized) Make Stylize's
.bg(color)
generic by @kdheepak in #1099This PR makes `.bg(color)` generic accepting anything that can be converted into `Color`; similar to the `.fg(color)` method on the same trait
-
4d1784f (uncategorized) Re-export ParseColorError as style::ParseColorError by @joshka in #1086
Bug Fixes
-
366cbae (buffer) Fix Debug panic and fix formatting of overridden parts by @EdJoPaTo in #1098
Fix panic in `Debug for Buffer` when `width == 0`. Also corrects the output when symbols are overridden.
-
4392759 (examples) Changed user_input example to work with multi-byte unicode chars by @OkieOth in #1069
This is the proposed solution for issue #1068. It solves the bug in the user_input example with multi-byte UTF-8 characters as input.
Fixes:#1068
-
20fc0dd (examples) Fix key handling in constraints by @psobolik in #1066
Add check for `KeyEventKind::Press` to constraints example's event handler to eliminate double keys on Windows.
Fixes:#1062
-
f4637d4 (reflow) Allow wrapping at zero width whitespace by @kxxt in #1074
-
699c2d7 (uncategorized) Unicode truncation bug by @joshka in #1089
- Rewrote the line / span rendering code to take into account how multi-byte / wide emoji characters are truncated when rendering into areas that cannot accommodate them in the available space - Added comprehensive coverage over the edge cases - Adds a benchmark to ensure perf
-
b30411d (uncategorized) Termwiz underline color test by @joshka in #1094
Fixes code that doesn't compile in the termwiz tests when underline-color feature is enabled.
-
5f1e119 (uncategorized) Correct feature flag typo for termwiz by @joshka in #1088
underline-color was incorrectly spelt as underline_color
-
0a16496 (uncategorized) Use
to_string
to serialize Color by @SleepySwords in #934Since deserialize now uses `FromStr` to deserialize color, serializing `Color` RGB values, as well as index values, would produce an output that would no longer be able to be deserialized without causing an error.
Color::Rgb will now be serialized as the hex representation of their value. For example, with serde_json,
Color::Rgb(255, 0, 255)
would be serialized as"#FF00FF"
rather than{"Rgb": [255, 0, 255]}
.Color::Indexed will now be serialized as just the string of the index. For example, with serde_json,
Color::Indexed(10)
would be serialized as"10"
rather than{"Indexed": 10}
.
Other color variants remain the same.
Refactor
-
2cfe82a (buffer) Deprecate assert_buffer_eq! in favor of assert_eq! by @EdJoPaTo in #1007
- Simplify `assert_buffer_eq!` logic. - Deprecate `assert_buffer_eq!`. - Introduce `TestBackend::assert_buffer_lines`. Also simplify many tests involving buffer comparisons. For the deprecation, just use `assert_eq` instead of `assert_buffer_eq`: ```diff -assert_buffer_eq!(actual, expected); +assert_eq!(actual, expected); ``` --- I noticed `assert_buffer_eq!` creating no test coverage reports and looked into this macro. First I simplified it. Then I noticed a bunch of `assert_eq!(buffer, …)` and other indirect usages of this macro (like `TestBackend::assert_buffer`). The good thing here is that it's mainly used in tests so not many changes to the library code.
-
baedc39 (buffer) Simplify set_stringn logic by @EdJoPaTo in #1083
-
9bd89c2 (clippy) Enable breaking lint checks by @EdJoPaTo in #988
We need to make sure to not change existing methods without a notice. But at the same time this also finds public additions with mistakes before they are even released which is what I would like to have. This renames a method and deprecated the old name hinting to a new name. Should this be mentioned somewhere, so it's added to the release notes? It's not breaking because the old method is still there.
-
bef5bcf (example) Remove pointless new method by @EdJoPaTo in #1038
Use `App::default()` directly.
Documentation
-
da1ade7 (github) Update code owners about past maintainers by @orhun in #1073
As per suggestion in https://github.com/ratatui-org/ratatui/pull/1067#issuecomment-2079766990 It's good for historical purposes!
-
3687f78 (github) Update code owners by @orhun in #1067
Removes the team members that are not able to review PRs recently (with their approval ofc)
-
839cca2 (table) Fix typo in docs for highlight_symbol by @kdheepak in #1108

-
366c2a0 (block) Use Block::bordered by @EdJoPaTo in #1041
Block::bordered()
is shorter thanBlock::new().borders(Borders::ALL)
, requires one less import (Borders
) and in caseBlock::default()
was used before can even beconst
. -
2e71c18 (buffer) Simplify Buffer::filled with macro by @EdJoPaTo in #1036
The `vec![]` macro is highly optimized by the Rust team and shorter. Don't do it manually. This change is mainly cleaner code. The only production code that uses this is `Terminal::with_options` and `Terminal::insert_before` so it's not performance relevant on every render.
-
81b9633 (calendar) Use const fn by @EdJoPaTo in #1039
Also, do the comparison without `as u8`. Stays the same at runtime and is cleaner code.
-
c442dfd (canvas) Change map data to const instead of static by @EdJoPaTo in #1037
-
1706b0a (crossterm) Speed up combined fg and bg color changes by up to 20% by @joshka in #1072
-
1a4bb1c (layout) Avoid allocating memory when using split ergonomic utils by @tranzystorekk in #1105
Don't create intermediate vec in `Layout::areas` and `Layout::spacers` when there's no need for one.
Styling
-
aa4260f (uncategorized) Use std::fmt instead of importing Debug and Display by @joshka in #1087
This is a small universal style change to avoid making this change a part of other PRs. [rationale](https://github.com/ratatui-org/ratatui/pull/1083#discussion_r1588466060)
Testing
Miscellaneous Tasks
-
5fbb77a (readme) Use terminal theme for badges by @TadoTheMiner in #1026
The badges in the readme were all the default theme. Giving them prettier colors that match the terminal gif is better. I've used the colors from the VHS repo.

76e5fe5 (uncategorized) Revert "Make Stylize's
.bg(color)

-
326a461 (uncategorized) Add package categories field by @mcskware in #1035
Add the package categories field in Cargo.toml, with value `["command-line-interface"]`. This fixes the (currently non-default) clippy cargo group lint [`clippy::cargo_common_metadata`](https://rust-lang.github.io/rust-clippy/master/index.html#/cargo_common_metadata). As per discussion in [Cargo package categories suggestions](https://github.com/ratatui-org/ratatui/discussions/1034), this lint is not suggested to be run by default in CI, but rather as an occasional one-off as part of the larger [`clippy::cargo`](https://doc.rust-lang.org/stable/clippy/lints.html#cargo) lint group.

Followup to https://github.com/ratatui-org/ratatui/pull/1035 and https://github.com/ratatui-org/ratatui/discussions/1034 It's reasonable to enable this and deal with breakage by fixing any specific issues that arise.

0.26.2 - 2024-04-15
This is a patch release that fixes bugs and adds enhancements, including new iterator constructors, List scroll padding, and various rendering improvements. ✨
✨ Release highlights: https://ratatui.rs/highlights/v0262/
Features
-
11b452d (layout) Mark various functions as const by @EdJoPaTo in #951
-
1cff511 (line) Impl Styled for Line by @joshka in #968
This adds `FromIterator` impls for `Line` and `Text` that allow creating `Line` and `Text` instances from iterators of `Span` and `Line` instances, respectively. ```rust let line = Line::from_iter(vec!["Hello".blue(), " world!".green()]); let line: Line = iter::once("Hello".blue()) .chain(iter::once(" world!".green())) .collect(); let text = Text::from_iter(vec!["The first line", "The second line"]); let text: Text = iter::once("The first line") .chain(iter::once("The second line")) .collect(); ```
-
654949b (list) Add Scroll Padding to Lists by @CameronBarnes in #958
Introduces scroll padding, which allows the api user to request that a certain number of ListItems be kept visible above and below the currently selected item while scrolling. ```rust let list = List::new(items).scroll_padding(1); ```
-
26af650 (text) Add push methods for text and line by @joshka in #998
Adds the following methods to the `Text` and `Line` structs: - Text::push_line - Text::push_span - Line::push_span This allows for adding lines and spans to a text object without having to call methods on the fields directly, which is useful for incremental construction of text objects.
-
b5bdde0 (text) Add
FromIterator
impls forLine
andText
by @joshka in #967This adds `FromIterator` impls for `Line` and `Text` that allow creating `Line` and `Text` instances from iterators of `Span` and `Line` instances, respectively. ```rust let line = Line::from_iter(vec!["Hello".blue(), " world!".green()]); let line: Line = iter::once("Hello".blue()) .chain(iter::once(" world!".green())) .collect(); let text = Text::from_iter(vec!["The first line", "The second line"]); let text: Text = iter::once("The first line") .chain(iter::once("The second line")) .collect(); ```

12f67e8 (uncategorized) Impl Widget for
&str
andString
by @kdheepak in #952Currently, `f.render_widget("hello world".bold(), area)` works but `f.render_widget("hello world", area)` doesn't. This PR changes that my implementing `Widget` for `&str` and `String`. This makes it easier to render strings with no styles as widgets. Example usage: ```rust terminal.draw(|f| f.render_widget("Hello World!", f.size()))?; ``` ---------
Bug Fixes
-
0207160 (line) Line truncation respects alignment by @TadoTheMiner in #987
When rendering a `Line`, the line will be truncated: - on the right for left aligned lines - on the left for right aligned lines - on bot sides for centered lines E.g. "Hello World" will be rendered as "Hello", "World", "lo wo" for left, right, centered lines respectively.
-
c56f49b (list) Saturating_sub to fix highlight_symbol overflow by @mrjackwills in #949
An overflow (pedantically an underflow) can occur if the highlight_symbol is a multi-byte char, and area is reduced to a size less than that char length.
-
943c043 (scrollbar) Dont render on 0 length track by @EdJoPaTo in #964
Fixes a panic when `track_length - 1` is used. (clamp panics on `-1.0` being smaller than `0.0`)
-
742a5ea (text) Fix panic when rendering out of bounds by @joshka in #997
Previously it was possible to cause a panic when rendering to an area outside of the buffer bounds. Instead this now correctly renders nothing to the buffer.
-
f6c4e44 (uncategorized) Ensure that paragraph correctly renders styled text by @joshka in #992
Paragraph was ignoring the new `Text::style` field added in 0.26.0
-
35e971f (uncategorized) Scrollbar thumb not visible on long lists by @ThomasMiz in #959
When displaying somewhat-long lists, the `Scrollbar` widget sometimes did not display a thumb character, and only the track will be visible.

6fd5f63 (lint) Prefer idiomatic for loops by @EdJoPaTo
-
37b957c (lints) Add lints to scrollbar by @EdJoPaTo
-
c12bcfe (non-src) Apply pedantic lints by @EdJoPaTo in #976
Fixes many not yet enabled lints (mostly pedantic) on everything that is not the lib (examples, benches, tests). Therefore, this is not containing anything that can be a breaking change. Lints are not enabled as that should be the job of #974. I created this as a separate PR as its mostly independent and would only clutter up the diff of #974 even more. Also see https://github.com/ratatui-org/ratatui/pull/974#discussion_r1506458743 ---------
-
8719608 (span) Rename to_aligned_line into into_aligned_line by @EdJoPaTo in #993
With the Rust method naming conventions these methods are into methods consuming the Span. Therefore, it's more consistent to use `into_` instead of `to_`. ```rust Span::to_centered_line Span::to_left_aligned_line Span::to_right_aligned_line ``` Are marked deprecated and replaced with the following ```rust Span::into_centered_line Span::into_left_aligned_line Span::into_right_aligned_line ```

Full Changelog: https://github.com/ratatui-org/ratatui/compare/v0.26.1...0.26.2
0.26.1 - 2024-02-12
This is a patch release that fixes bugs and adds enhancements, including new iterators, title options for blocks, and various rendering improvements. ✨
Features
-
74a0511 (rect) Add Rect::positions iterator (#928)
Useful for performing some action on all the cells in a particular area. E.g., ```rust fn render(area: Rect, buf: &mut Buffer) { for position in area.positions() { buf.get_mut(position.x, position.y).set_symbol("x"); } } ```
-
9182f47 (uncategorized) Add Block::title_top and Block::title_top_bottom (#940)
This adds the ability to add titles to the top and bottom of a block without having to use the `Title` struct (which will be removed in a future release - likely v0.28.0). Fixes a subtle bug if the title was created from a right aligned Line and was also right aligned. The title would be rendered one cell too far to the right. ```rust Block::bordered() .title_top(Line::raw("A").left_aligned()) .title_top(Line::raw("B").centered()) .title_top(Line::raw("C").right_aligned()) .title_bottom(Line::raw("D").left_aligned()) .title_bottom(Line::raw("E").centered()) .title_bottom(Line::raw("F").right_aligned()) .render(buffer.area, &mut buffer); // renders "┌A─────B─────C┐", "│ │", "└D─────E─────F┘", ``` Addresses part of https://github.com/ratatui-org/ratatui/issues/738
Bug Fixes
-
2202059 (block) Fix crash on empty right aligned title (#933)
- Simplified implementation of the rendering for block. - Introduces a subtle rendering change where centered titles that are odd in length will now be rendered one character to the left compared to before. This aligns with other places that we render centered text and is a more consistent behavior. See https://github.com/ratatui-org/ratatui/pull/807#discussion_r1455645954 for another example of this.
-
14c67fb (list) Highlight symbol when using a multi-bytes char (#924)
ratatui v0.26.0 brought a regression in the List widget, in which the highlight symbol width was incorrectly calculated - specifically when the highlight symbol was a multi-char character, e.g. `▶`.
-
0dcdbea (paragraph) Render Line::styled correctly inside a paragraph (#930)
Renders the styled graphemes of the line instead of the contained spans.
-
fae5862 (uncategorized) Ensure that buffer::set_line sets the line style (#926)
Fixes a regression in 0.26 where buffer::set_line was no longer setting the style. This was due to the new style field on Line instead of being stored only in the spans. Also adds a configuration for just running unit tests to bacon.toml.

This adds convenience functions `left_aligned()`, `centered()` and `right_aligned()` plus unit tests. Updated example code.
-
0df9354 (padding) Add new constructors for padding (#828)
Adds `proportional`, `symmetric`, `left`, `right`, `top`, and `bottom` constructors for Padding struct. Proportional is ``` /// **NOTE**: Terminal cells are often taller than they are wide, so to make horizontal and vertical /// padding seem equal, doubling the horizontal padding is usually pretty good. ```
-
d726e92 (paragraph) Add alignment convenience functions (#866)
Added convenience functions left_aligned(), centered() and right_aligned() plus unit tests. Updated example code.
-
c1ed5c3 (span) Add alignment functions (#873)

Closes #853
-
b80264d (text) Add alignment convenience functions (#862)
Adds convenience functions `left_aligned()`, `centered()` and `right_aligned()` plus unit tests.
-
23f6938 (block) Add
Block::bordered
(#736)This avoid creating a block with no borders and then settings Borders::ALL. i.e. ```diff - Block::default().borders(Borders::ALL); + Block::bordered(); ```
-
ffd5fc7 (color) Add Color::from_u32 constructor (#785)
Convert a u32 in the format 0x00RRGGBB to a Color. ```rust let white = Color::from_u32(0x00FFFFFF); let black = Color::from_u32(0x00000000); ```
-
4f2db82 (color) Use the FromStr implementation for deserialization (#705)
The deserialize implementation for Color used to support only the enum names (e.g. Color, LightRed, etc.) With this change, you can use any of the strings supported by the FromStr implementation (e.g. black, light-red, #00ff00, etc.)
-
1cbe1f5 (constraints) Rename
Constraint::Proportional
toConstraint::Fill
(#880)Constraint::Fill
is a more intuitive name for the behavior, and it is shorter.Resolves #859

540fd2d (layout) Change
Flex::default()
(#881) [breaking]This PR makes a number of simplifications to the layout and constraint features that were added after v0.25.0. For users upgrading from v0.25.0, the net effect of this PR (along with the other PRs) is the following: - New `Flex` modes have been added. - `Flex::Start` (new default) - `Flex::Center` - `Flex::End` - `Flex::SpaceAround` - `Flex::SpaceBetween` - `Flex::Legacy` (old default) - `Min(v)` grows to allocate excess space in all `Flex` modes instead of shrinking (except in `Flex::Legacy` where it retains old behavior). - `Fill(1)` grows to allocate excess space, growing equally with `Min(v)`. --- The following contains a summary of the changes in this PR and the motivation behind them. **`Flex`** - Removes `Flex::Stretch` - Renames `Flex::StretchLast` to `Flex::Legacy` **`Constraint`** - Removes `Fixed` - Makes `Min(v)` grow as much as possible everywhere (except `Flex::Legacy` where it retains the old behavior) - Makes `Min(v)` grow equally as `Fill(1)` while respecting `Min` lower bounds. When `Fill` and `Min` are used together, they both fill excess space equally. Allowing `Min(v)` to grow still allows users to build the same layouts as before with `Flex::Start` with no breaking changes to the behavior. This PR also removes the unstable feature `SegmentSize`. This is a breaking change to the behavior of constraints. If users want old behavior, they can use `Flex::Legacy`. ```rust Layout::vertical([Length(25), Length(25)]).flex(Flex::Legacy) ``` Users that have constraint that exceed the available space will probably not see any difference or see an improvement in their layouts. Any layout with `Min` will be identical in `Flex::Start` and `Flex::Legacy` so any layout with `Min` will not be breaking. Previously, `Table` used `EvenDistribution` internally by default, but with that gone the default is now `Flex::Start`. This changes the behavior of `Table` (for the better in most cases). The only way for users to get exactly the same as the old behavior is to change their constraints. I imagine most users will be happier out of the box with the new Table default. Resolves https://github.com/ratatui-org/ratatui/issues/843 Thanks to @joshka for the direction

bbcfa55 (layout) Add Rect::contains method (#882)
This is useful for performing hit tests (i.e. did the user click in an area).
-
1e75596 (layout) Increase default cache size to 500 (#850)
This is a somewhat arbitrary size for the layout cache based on adding the columns and rows on my laptop's terminal (171+51 = 222) and doubling it for good measure and then adding a bit more to make it a round number. This gives enough entries to store a layout for every row and every column, twice over, which should be enough for most apps. For those that need more, the cache size can be set with `Layout::init_cache()`.
-
2819eea (layout) Add Position struct (#790)
This stores the x and y coordinates (columns and rows) - add conversions from Rect - add conversion with Size to Rect - add Rect::as_position
-
1561d64 (layout) Add Rect -> Size conversion methods (#789)
- add Size::new() constructor - add Rect::as_size() - impl From<Rect> for Size - document and add tests for Size
-
f13fd73 (layout) Add
Rect::clamp()
method (#749)* feat(layout): add a Rect::clamp() method This ensures a rectangle does not end up outside an area. This is useful when you want to be able to dynamically move a rectangle around, but keep it constrained to a certain area. For example, this can be used to implement a draggable window that can be moved around, but not outside the terminal window. ```rust let window_area = Rect::new(state.x, state.y, 20, 20).clamp(area); state.x = rect.x; state.y = rect.y; ``` * refactor: use rstest to simplify clamp test * fix: use rstest description instead of string test layout::rect::tests::clamp::case_01_inside ... ok test layout::rect::tests::clamp::case_02_up_left ... ok test layout::rect::tests::clamp::case_04_up_right ... ok test layout::rect::tests::clamp::case_05_left ... ok test layout::rect::tests::clamp::case_03_up ... ok test layout::rect::tests::clamp::case_06_right ... ok test layout::rect::tests::clamp::case_07_down_left ... ok test layout::rect::tests::clamp::case_08_down ... ok test layout::rect::tests::clamp::case_09_down_right ... ok test layout::rect::tests::clamp::case_10_too_wide ... ok test layout::rect::tests::clamp::case_11_too_tall ... ok test layout::rect::tests::clamp::case_12_too_large ... ok * fix: less ambiguous docs for this / other rect * fix: move rstest to dev deps
-
98bcf1c (layout) Add Rect::split method (#729)
This method splits a Rect and returns a fixed-size array of the resulting Rects. This allows the caller to use array destructuring to get the individual Rects. ```rust use Constraint::*; let layout = &Layout::vertical([Length(1), Min(0)]); let [top, main] = area.split(&layout); ```
-
0494ee5 (layout) Accept Into for constructors (#744)
This allows Layout constructors to accept any type that implements Into<Constraint> instead of just AsRef<Constraint>. This is useful when you want to specify a fixed size for a layout, but don't want to explicitly create a Constraint::Length yourself. ```rust Layout::new(Direction::Vertical, [1, 2, 3]); Layout::horizontal([1, 2, 3]); Layout::vertical([1, 2, 3]); Layout::default().constraints([1, 2, 3]); ```
-
7ab12ed (layout) Add horizontal and vertical constructors (#728)
* feat(layout): add vertical and horizontal constructors This commit adds two new constructors to the `Layout` struct, which allow the user to create a vertical or horizontal layout with default values. ```rust let layout = Layout::vertical([ Constraint::Length(10), Constraint::Min(5), Constraint::Length(10), ]); let layout = Layout::horizontal([ Constraint::Length(10), Constraint::Min(5), Constraint::Length(10), ]); ```
-
4278b40 (line) Implement iterators for Line (#896)
This allows iterating over the `Span`s of a line using `for` loops and other iterator methods. - add `iter` and `iter_mut` methods to `Line` - implement `IntoIterator` for `Line`, `&Line`, and `&mut Line` traits - update call sites to iterate over `Line` rather than `Line::spans`
-
5d410c6 (line) Implement Widget for Line (#715)
This allows us to use Line as a child of other widgets, and to use Line::render() to render it rather than calling buffer.set_line(). ```rust frame.render_widget(Line::raw("Hello, world!"), area); // or Line::raw("Hello, world!").render(frame, area); ```
-
c977293 (line) Add style field, setters and docs (#708) [breaking]
- The `Line` struct now stores the style of the line rather than each `Span` storing it. - Adds two new setters for style and spans - Adds missing docs
BREAKING CHANGE:
Line::style
is now a field ofLine
instead of being stored in eachSpan
. -
bbf2f90 (rect.rs) Implement Rows and Columns iterators in Rect (#765)
This enables iterating over rows and columns of a Rect. In tern being able to use that with other iterators and simplify looping over cells.
-
fe06f0c (serde) Support TableState, ListState, and ScrollbarState (#723)
TableState, ListState, and ScrollbarState can now be serialized and deserialized using serde. ```rust #[derive(Debug, Clone, serde::Serialize, serde::Deserialize)] struct AppState { list_state: ListState, table_state: TableState, scrollbar_state: ScrollbarState, } let app_state = AppState::default(); let serialized = serde_json::to_string(app_state); let app_state = serde_json::from_str(serialized); ```
-
37c1836 (span) Implement Widget on Span (#709)
This allows us to use Span as a child of other widgets, and to use Span::render() to render it rather than calling buffer.set_span(). ```rust frame.render_widget(Span::raw("Hello, world!"), area); // or Span::raw("Hello, world!").render(frame, area); // or even "Hello, world!".green().render(frame, area); ```
-
e1e85aa (style) Add material design color palette (#786)
The `ratatui::style::palette::material` module contains the Google 2014 Material Design palette. See https://m2.material.io/design/color/the-color-system.html#tools-for-picking-colors for more information. ```rust use ratatui::style::palette::material::BLUE_GRAY; Line::styled("Hello", BLUE_GRAY.c500); ```
-
bf67850 (style) Add tailwind color palette (#787)
The `ratatui::style::palette::tailwind` module contains the default Tailwind color palette. This is useful for styling components with colors that match the Tailwind color palette. See https://tailwindcss.com/docs/customizing-colors for more information on Tailwind. ```rust use ratatui::style::palette::tailwind::SLATE; Line::styled("Hello", SLATE.c500); ```

-
a489d85 (table) Deprecate SegmentSize on table (#842)
This adds for table: - Added new flex method with flex field - Deprecated segment_size method and removed segment_size field - Updated documentation - Updated tests
-
c69ca47 (table) Collect iterator of
Row
intoTable
(#774) [breaking]Any iterator whose item is convertible into `Row` can now be collected into a `Table`. Where previously, `Table::new` accepted `IntoIterator<Item = Row>`, it now accepts `IntoIterator<Item: Into<Row>>`.
BREAKING CHANGE:The compiler can no longer infer the element type of the container passed to
Table::new()
. For example,Table::new(vec![], widths)
will no longer compile, as the type ofvec![]
can no longer be inferred. -
2faa879 (table) Accept Text for highlight_symbol (#781)
This allows for multi-line symbols to be used as the highlight symbol. ```rust let table = Table::new(rows, widths) .highlight_symbol(Text::from(vec![ "".into(), " █ ".into(), " █ ".into(), "".into(), ])); ```
-
e64e194 (table) Implement FromIterator for widgets::Row (#755)
The `Row::new` constructor accepts a single argument that implements `IntoIterator`. This commit adds an implementation of `FromIterator`, as a thin wrapper around `Row::new`. This allows `.collect::<Row>()` to be used at the end of an iterator chain, rather than wrapping the entire iterator chain in `Row::new`.
-
803a72d (table) Accept Into for widths (#745)
This allows Table constructors to accept any type that implements Into<Constraint> instead of just AsRef<Constraint>. This is useful when you want to specify a fixed size for a table columns, but don't want to explicitly create a Constraint::Length yourself. ```rust Table::new(rows, [1,2,3]) Table::default().widths([1,2,3]) ```
-
f025d2b (table) Add Table::footer and Row::top_margin methods (#722)
* feat(table): Add a Table::footer method
-
f29c73f (tabs) Accept Iterators of
Line
in constructors (#776) [breaking]Any iterator whose item is convertible into `Line` can now be collected into `Tabs`. In addition, where previously `Tabs::new` required a `Vec`, it can now accept any object that implements `IntoIterator` with an item type implementing `Into<Line>`.
BREAKING CHANGE:Calls to
Tabs::new()
whose argument is collected from an iterator will no longer compile. For example,Tabs::new(["a","b"].into_iter().collect())
will no longer compile, because the return type of.collect()
can no longer be inferred to be aVec<_>
. -
b459228 (termwiz) Add
From
termwiz style impls (#726)Important note: this also fixes a wrong mapping between ratatui's gray and termwiz's grey. `ratatui::Color::Gray` now maps to `termwiz::color::AnsiColor::Silver`
-
9ba7354 (text) Implement iterators for Text (#900)
This allows iterating over the `Lines`s of a text using `for` loops and other iterator methods. - add `iter` and `iter_mut` methods to `Text` - implement `IntoIterator` for `Text`, `&Text`, and `&mut Text` traits - update call sites to iterate over `Text` rather than `Text::lines`
-
68d5783 (text) Add style and alignment (#807)
Fixes #758, fixes #801
This PR adds:
style

manual draw to call for Widget impl
All places that use Text

features expect paragraph which still has a custom implementation.
-
815757f (widgets) Implement Widget for Widget refs (#833)
Many widgets can be rendered without changing their state. This commit implements The `Widget` trait for references to widgets and changes their implementations to be immutable. This allows us to render widgets without consuming them by passing a ref to the widget when calling `Frame::render_widget()`. ```rust // this might be stored in a struct let paragraph = Paragraph::new("Hello world!"); let [left, right] = area.split(&Layout::horizontal([20, 20])); frame.render_widget(¶graph, left); frame.render_widget(¶graph, right); // we can reuse the widget ``` Implemented for all widgets except BarChart (which has an implementation that modifies the internal state and requires a rewrite to fix. Other widgets will be implemented in follow up commits.

eb79256 (widgets) Collect iterator of
ListItem

c8dd879 (uncategorized) Add WidgetRef and StatefulWidgetRef traits (#903)
The Widget trait consumes self, which makes it impossible to use in a boxed context. Previously we implemented the Widget trait for &T, but this was not enough to render a boxed widget. We now have a new trait called `WidgetRef` that allows rendering a widget by reference. This trait is useful when you want to store a reference to one or more widgets and render them later. Additionally this makes it possible to render boxed widgets where the type is not known at compile time (e.g. in a composite layout with multiple panes of different types). This change also adds a new trait called `StatefulWidgetRef` which is the stateful equivalent of `WidgetRef`. Both new traits are gated behind the `unstable-widget-ref` feature flag as we may change the exact name / approach a little on this based on further discussion. Blanket implementation of `Widget` for `&W` where `W` implements `WidgetRef` and `StatefulWidget` for `&W` where `W` implements `StatefulWidgetRef` is provided. This allows you to render a widget by reference and a stateful widget by reference. A blanket implementation of `WidgetRef` for `Option<W>` where `W` implements `WidgetRef` is provided. This makes it easier to render child widgets that are optional without the boilerplate of unwrapping the option. Previously several widgets implemented this manually. This commits expands the pattern to apply to all widgets. ```rust struct Parent { child: Option<Child>, } impl WidgetRef for Parent { fn render_ref(&self, area: Rect, buf: &mut Buffer) { self.child.render_ref(area, buf); } } ``` ```rust let widgets: Vec<Box<dyn WidgetRef>> = vec![Box::new(Greeting), Box::new(Farewell)]; for widget in widgets { widget.render_ref(buf.area, &mut buf); } assert_eq!(buf, Buffer::with_lines(["Hello Goodbye"])); ```

https://github.com/ratatui-org/ratatui/assets/1813121/08d7d8f6-d013-44b4-8331-f4eee3589cce
It allows users to interactive explore how the constraints behave with respect to each other and compare that across flex modes. It allows users to swap constraints out for other constraints, increment or decrement the values, add and remove constraints, and add spacing
It is also a good example for how to structure a simple TUI with several Ratatui code patterns that are useful for refactoring.

dd5ca3a (uncategorized) Better weights for constraints (#889)
This PR is a split of reworking the weights from #888 This keeps the same ranking of weights, just uses a different numerical value so that the lowest weight is `WEAK` (`1.0`). No tests are changed as a result of this change, and running the following multiple times did not cause any errors for me: ```rust for i in {0..100} do cargo test --lib -- if [ $? -ne 0 ]; then echo "Test failed. Exiting loop." break fi done ```

be4fdaa (uncategorized) Change priority of constraints and add
split_with_spacers
✨ (#788)Follow up to https://github.com/ratatui-org/ratatui/pull/783 This PR introduces different priorities for each kind of constraint. This PR also adds tests that specifies this behavior. This PR resolves a number of broken tests. Fixes https://github.com/ratatui-org/ratatui/issues/827 With this PR, the layout algorithm will do the following in order: 1. Ensure that all the segments are within the user provided area and ensure that all segments and spacers are aligned next to each other 2. if a user provides a `layout.spacing`, it will enforce it. 3. ensure proportional elements are all proportional to each other 4. if a user provides a `Fixed(v)` constraint, it will enforce it. 5. `Min` / `Max` binding inequality constraints 6. `Length` 7. `Percentage` 8. `Ratio` 9. collapse `Min` or collapse `Max` 10. grow `Proportional` as much as possible 11. grow spacers as much as possible This PR also returns the spacer areas as `Rects` to the user. Users can then draw into the spacers as they see fit (thanks @joshka for the idea). Here's a screenshot with the modified flex example: <img width="569" alt="image" src="https://github.com/ratatui-org/ratatui/assets/1813121/46c8901d-882c-43b0-ba87-b1d455099d8f"> This PR introduces a `strengths` module that has "default" weights that give stable solutions as well as predictable behavior.

d713201 (uncategorized) Add
Color::from_hsl
✨ (#772)This PR adds `Color::from_hsl` that returns a valid `Color::Rgb`. ```rust let color: Color = Color::from_hsl(360.0, 100.0, 100.0); assert_eq!(color, Color::Rgb(255, 255, 255)); let color: Color = Color::from_hsl(0.0, 0.0, 0.0); assert_eq!(color, Color::Rgb(0, 0, 0)); ``` HSL stands for Hue (0-360 deg), Saturation (0-100%), and Lightness (0-100%) and working with HSL the values can be more intuitive. For example, if you want to make a red color more orange, you can change the Hue closer toward yellow on the color wheel (i.e. increase the Hue).

9df6ceb (uncategorized) Table column calculation uses layout spacing ✨ (#824)
This uses the new `spacing` feature of the `Layout` struct to allocate columns spacing in the `Table` widget. This changes the behavior of the table column layout in the following ways: 1. Selection width is always allocated. - if a user does not want a selection width ever they should use `HighlightSpacing::Never` 2. Column spacing is prioritized over other constraints - if a user does not want column spacing, they should use `Table::new(...).column_spacing(0)` ---------

For example, with the `flex` example you can get this effect (top is mcgugan wide, bottom is mcgugan tall): <img width="759" alt="image" src="https://github.com/ratatui-org/ratatui/assets/1813121/756bb50e-f8c3-4eec-abe8-ce358058a526"> <img width="759" alt="image" src="https://github.com/ratatui-org/ratatui/assets/1813121/583485ef-9eb2-4b45-ab88-90bd7cb14c54"> As of this PR, `MCGUGAN_WIDE` has to be styled manually, like so: ```rust let main_color = color_for_constraint(*constraint); let cell = buf.get_mut(block.x, block.y + 1); cell.set_style(Style::reset().fg(main_color).reversed()); let cell = buf.get_mut(block.x, block.y + 2); cell.set_style(Style::reset().fg(main_color).reversed()); let cell = buf.get_mut(block.x + block.width.saturating_sub(1), block.y + 1); cell.set_style(Style::reset().fg(main_color).reversed()); let cell = buf.get_mut(block.x + block.width.saturating_sub(1), block.y + 2); cell.set_style(Style::reset().fg(main_color).reversed()); ``` `MCGUGAN_TALL` has to be styled manually, like so: ```rust let main_color = color_for_constraint(*constraint); for x in block.x + 1..(block.x + block.width).saturating_sub(1) { let cell = buf.get_mut(x, block.y); cell.set_style(Style::reset().fg(main_color).reversed()); let cell = buf.get_mut(x, block.y + block.height - 1); cell.set_style(Style::reset().fg(main_color).reversed()); } ```

de97a1f (uncategorized) Add flex to layout ✨
This PR adds a new way to space elements in a `Layout`. Loosely based on [flexbox](https://css-tricks.com/snippets/css/a-guide-to-flexbox/), this PR adds a `Flex` enum with the following variants: - Start - Center - End - SpaceAround - SpaceBetween <img width="380" alt="image" src="https://github.com/ratatui-org/ratatui/assets/1813121/b744518c-eae7-4e35-bbc4-fe3c95193cde"> It also adds two more variants, to make this backward compatible and to make it replace `SegmentSize`: - StretchLast (default in the `Flex` enum, also behavior matches old default `SegmentSize::LastTakesRemainder`) - Stretch (behavior matches `SegmentSize::EvenDistribution`) The `Start` variant from above matches `SegmentSize::None`. This allows `Flex` to be a complete replacement for `SegmentSize`, hence this PR also deprecates the `segment_size` constructor on `Layout`. `SegmentSize` is still used in `Table` but under the hood `segment_size` maps to `Flex` with all tests passing unchanged. I also put together a simple example for `Flex` layouts so that I could test it visually, shared below:

8f56fab (uncategorized) Accept Color and Modifier for all Styles (#720) [breaking]
* feat: accept Color and Modifier for all Styles All style related methods now accept `S: Into<Style>` instead of `Style`. `Color` and `Modifier` implement `Into<Style>` so this is allows for more ergonomic usage. E.g.: ```rust Line::styled("hello", Style::new().red()); Line::styled("world", Style::new().bold()); // can now be simplified to
Line::styled("hello", Color::Red);
Line::styled("world", Modifier::BOLD);
Fixes https://github.com/ratatui-org/ratatui/issues/694
BREAKING CHANGE:All style related methods now accept `S: Into<Style>`
instead of `Style`. This means that if you are already passing an
ambiguous type that implements `Into<Style>` you will need to remove
the `.into()` call.
`Block` style methods can no longer be called from a const context as
trait functions cannot (yet) be const.
* feat: add tuple conversions to Style
Adds conversions for various Color and Modifier combinations
* chore: add unit tests

6645d2e (table) Ensure that default and new() match (#751) [breaking]
In https://github.com/ratatui-org/ratatui/pull/660 we introduced the segment_size field to the Table struct. However, we forgot to update the default() implementation to match the new() implementation. This meant that the default() implementation picked up SegmentSize::default() instead of SegmentSize::None. Additionally the introduction of Table::default() in an earlier PR, https://github.com/ratatui-org/ratatui/pull/339, was also missing the default for the column_spacing field (1). This commit fixes the default() implementation to match the new() implementation of these two fields by implementing the Default trait manually.
BREAKING CHANGE:The default() implementation of Table now sets the column_spacing field to 1 and the segment_size field to
SegmentSize::None. This will affect the rendering of a small amount of apps.

7f42ec9 (colors_rgb) Impl widget on mutable refs (#865)
This commit refactors the colors_rgb example to implement the Widget trait on mutable references to the app and its sub-widgets. This allows the app to update its state while it is being rendered. Additionally the main and run functions are refactored to be similar to the other recent examples. This uses a pattern where the App struct has a `run` method that takes a terminal as an argument, and the main function is in control of initializing and restoring the terminal and installing the error hooks.

(#672) [breaking]This allows to build list like ``` List::new(["Item 1", "Item 2"]) ```
-
8bfd666 (paragraph) Add
line_count
andline_width
unstable helper methodsThis is an unstable feature that may be removed in the future
-
1229b96 (rect) Add
offset
method (#533)The offset method creates a new Rect that is moved by the amount specified in the x and y direction. These values can be positive or negative. This is useful for manual layout tasks. ```rust let rect = area.offset(Offset { x: 10, y -10 }); ```
-
edacaf7 (buffer) Deprecate
Cell::symbol
field (#624)The Cell::symbol field is now accessible via a getter method (`symbol()`). This will allow us to make future changes to the Cell internals such as replacing `String` with `compact_str`.
-
6b2efd0 (layout) Accept IntoIterator for constraints (#663)
Layout and Table now accept IntoIterator for constraints with an Item that is AsRef<Constraint>. This allows pretty much any collection of constraints to be passed to the layout functions including arrays, vectors, slices, and iterators (without having to call collect() on them).
-
753e246 (layout) Allow configuring layout fill (#633)
The layout split will generally fill the remaining area when `split()` is called. This change allows the caller to configure how any extra space is allocated to the `Rect`s. This is useful for cases where the caller wants to have a fixed size for one of the `Rect`s, and have the other `Rect`s fill the remaining space. For now, the method and enum are marked as unstable because the exact name is still being bikeshedded. To enable this functionality, add the `unstable-segment-size` feature flag in your `Cargo.toml`. To configure the layout to fill the remaining space evenly, use `Layout::segment_size(SegmentSize::EvenDistribution)`. The default behavior is `SegmentSize::LastTakesRemainder`, which gives the last segment the remaining space. `SegmentSize::None` will disable this behavior. See the docs for `Layout::segment_size()` and `layout::SegmentSize` for more information. Fixes https://github.com/ratatui-org/ratatui/issues/536
-
1e2f0be (layout) Add parameters to Layout::new() (#557) [breaking]
Adds a convenience function to create a layout with a direction and a list of constraints which are the most common parameters that would be generally configured using the builder pattern. The constraints can be passed in as any iterator of constraints. ```rust let layout = Layout::new(Direction::Horizontal, [ Constraint::Percentage(50), Constraint::Percentage(50), ]); ```
-
c862aa5 (list) Support line alignment (#599)
The `List` widget now respects the alignment of `Line`s and renders them as expected.
-
ebf1f42 (style) Implement
From
trait for crossterm toStyle
related structs (#686) -
e49385b (table) Add a Table::segment_size method (#660)
It controls how to distribute extra space to an underconstrained table. The default, legacy behavior is to leave the extra space unused. The new options are LastTakesRemainder which gets all space to the rightmost column that can used it, and EvenDistribution which divides it amongst all columns.
-
b8f71c0 (widgets/chart) Add option to set the position of legend (#378)
-
5bf4f52 (uncategorized) Implement
From
trait for termion toStyle
related structs (#692)* feat(termion): implement from termion color * feat(termion): implement from termion style * feat(termion): implement from termion `Bg` and `Fg`
-
d19b266 (uncategorized) Add Constraint helpers (e.g. from_lengths) (#641)
Adds helper methods that convert from iterators of u16 values to the specific Constraint type. This makes it easy to create constraints like: ```rust // a fixed layout let constraints = Constraint::from_lengths([10, 20, 10]); // a centered layout let constraints = Constraint::from_ratios([(1, 4), (1, 2), (1, 4)]); let constraints = Constraint::from_percentages([25, 50, 25]); // a centered layout with a minimum size let constraints = Constraint::from_mins([0, 100, 0]); // a sidebar / main layout with maximum sizes let constraints = Constraint::from_maxes([30, 200]); ```
Bug Fixes
-
f69d57c (rect) Fix underflow in the
Rect::intersection
method (#678) -
56fc410 (block) Make
inner
aware of title positions (#657)Previously, when computing the inner rendering area of a block, all titles were assumed to be positioned at the top, which caused the height of the inner area to be miscalculated.
-
ec7b387 (doc) Do not access deprecated
Cell::symbol
field in doc example (#626) -
37c70db (table) Add widths parameter to new() (#664) [breaking]
This prevents creating a table that doesn't actually render anything.
-
1f88da7 (table) Fix new clippy lint which triggers on table widths tests (#630)
* fix(table): new clippy lint in 1.74.0 triggers on table widths tests
-
36d8c53 (table) Widths() now accepts AsRef<[Constraint]> (#628)
This allows passing an array, slice or Vec of constraints, which is more ergonomic than requiring this to always be a slice. The following calls now all succeed: ```rust Table::new(rows).widths([Constraint::Length(5), Constraint::Length(5)]); Table::new(rows).widths(&[Constraint::Length(5), Constraint::Length(5)]); // widths could also be computed at runtime let widths = vec![Constraint::Length(5), Constraint::Length(5)]; Table::new(rows).widths(widths.clone()); Table::new(rows).widths(&widths); ```
-
34d099c (tabs) Fixup tests broken by semantic merge conflict (#665)
Two changes without any line overlap caused the tabs tests to break
-
e4579f0 (tabs) Set the default highlight_style (#635) [breaking]
Previously the default highlight_style was set to `Style::default()`, which meant that the highlight style was the same as the normal style. This change sets the default highlight_style to reversed text.
-
28ac55b (tabs) Tab widget now supports custom padding (#629)
The Tab widget now contains padding_left and and padding_right properties. Those values can be set with functions `padding_left()`, `padding_right()`, and `padding()` which all accept `Into<Line>`. Fixes issue https://github.com/ratatui-org/ratatui/issues/502
-
df0eb1f (terminal) Insert_before() now accepts lines > terminal height and doesn't add an extra blank line (#596)
Fixes issue with inserting content with height>viewport_area.height and adds the ability to insert content of height>terminal_height - Adds TestBackend::append_lines() and TestBackend::clear_region() methods to support testing the changes
-
aaeba27 (uncategorized) Truncate table when overflow (#685)
This prevents a panic when rendering an empty right aligned and rightmost table cell

-
f767ea7 (list)
start_corner
is nowdirection
(#673)The previous name `start_corner` did not communicate clearly the intent of the method. A new method `direction` and a new enum `ListDirection` were added. `start_corner` is now deprecated
-
0576a8a (layout) To natural reading order (#681)
Structs and enums at the top of the file helps show the interaction between the types without having to find each type in between longer impl sections. Also moved the try_split function into the Layout impl as an associated function and inlined the `layout::split()` which just called try_split. This makes the code a bit more contained.
-
4be18ab (readme) Reference awesome-ratatui instead of wiki (#689)
* refactor(readme): link awesome-ratatui instead of wiki The apps wiki moved to awesome-ratatui * docs(readme): Update README.md

0.24.0 - 2023-10-23
We are excited to announce the new version of ratatui
- a Rust library that's all about cooking up TUIs 🐭
In this version, we've introduced features like window size API, enhanced chart rendering, and more. The list of *breaking changes* can be found here ⚠️. Also, we created various tutorials and walkthroughs in Ratatui Book which is available at https://ratatui.rs 🚀
✨ Release highlights: https://ratatui.rs/highlights/v024
Features
-
c6c3f88 (backend) Implement common traits for
WindowSize
(#586) -
d077903 (backend) Backend provides window_size, add Size struct (#276)
For image (sixel, iTerm2, Kitty...) support that handles graphics in terms of `Rect` so that the image area can be included in layouts. For example: an image is loaded with a known pixel-size, and drawn, but the image protocol has no mechanism of knowing the actual cell/character area that been drawn on. It is then impossible to skip overdrawing the area. Returning the window size in pixel-width / pixel-height, together with columns / rows, it can be possible to account the pixel size of each cell / character, and then known the `Rect` of a given image, and also resize the image so that it fits exactly in a `Rect`. Crossterm and termwiz also both return both sizes from one syscall, while termion does two. Add a `Size` struct for the cases where a `Rect`'s `x`/`y` is unused (always zero). `Size` is not "clipped" for `area < u16::max_value()` like `Rect`. This is why there are `From` implementations between the two.
-
301366c (barchart) Render charts smaller than 3 lines (#532)
The bar values are not shown if the value width is equal the bar width and the bar is height is less than one line Add an internal structure `LabelInfo` which stores the reserved height for the labels (0, 1 or 2) and also whether the labels will be shown. Fixes ratatui-org#513
-
32e4619 (block) Allow custom symbols for borders (#529) [breaking]
Adds a new `Block::border_set` method that allows the user to specify the symbols used for the border. Added two new border types: `BorderType::QuadrantOutside` and `BorderType::QuadrantInside`. These are used to draw borders using the unicode quadrant characters (which look like half block "pixels"). ``` ▛▀▀▜ ▌ ▐ ▙▄▄▟ ▗▄▄▖ ▐ ▌ ▝▀▀▘ ``` Fixes: https://github.com/ratatui-org/ratatui/issues/528 BREAKING CHANGES: - BorderType::to_line_set is renamed to to_border_set - BorderType::line_symbols is renamed to border_symbols
-
4541336 (canvas) Implement half block marker (#550)
* feat(canvas): implement half block marker A useful technique for the terminal is to use half blocks to draw a grid of "pixels" on the screen. Because we can set two colors per cell, and because terminal cells are about twice as tall as they are wide, we can draw a grid of half blocks that looks like a grid of square pixels. This commit adds a new `HalfBlock` marker that can be used in the Canvas widget and the associated HalfBlockGrid. Also updated demo2 to use the new marker as it looks much nicer. Adds docs for many of the methods and structs on canvas. Changes the grid resolution method to return the pixel count rather than the index of the last pixel. This is an internal detail with no user impact.
-
082cbcb (frame) Remove generic Backend parameter (#530) [breaking]
This change simplifies UI code that uses the Frame type. E.g.: ```rust fn draw<B: Backend>(frame: &mut Frame<B>) { // ... } ``` Frame was generic over Backend because it stored a reference to the terminal in the field. Instead it now directly stores the viewport area and current buffer. These are provided at creation time and are valid for the duration of the frame. BREAKING CHANGE: Frame is no longer generic over Backend. Code that accepted a Frame<Backend> will now need to accept a Frame.
-
d67fa2c (line) Add
Line::raw
constructor (#511)* feat(line): add `Line::raw` constructor There is already `Span::raw` and `Text::raw` methods and this commit simply adds `Line::raw` method for symmetry. Multi-line content is converted to multiple spans with the new line removed
-
cbf86da (rect) Add is_empty() to simplify some common checks (#534)
- add `Rect::is_empty()` that checks whether either height or width == 0 - refactored `Rect` into layout/rect.rs from layout.rs. No public API change as the module is private and the type is re-exported under the `layout` module.
-
15641c8 (uncategorized) Add
buffer_mut
method onFrame
✨ (#548)
Bug Fixes
-
638d596 (layout) Use LruCache for layout cache (#487)
The layout cache now uses a LruCache with default size set to 16 entries. Previously the cache was backed by a HashMap, and was able to grow without bounds as a new entry was added for every new combination of layout parameters. - Added a new method (`layout::init_cache(usize)`) that allows the cache size to be changed if necessary. This will only have an effect if it is called prior to any calls to `layout::split()` as the cache is wrapped in a `OnceLock`
-
8d507c4 (backend) Add feature flag for underline-color (#570)
Windows 7 doesn't support the underline color attribute, so we need to make it optional. This commit adds a feature flag for the underline color attribute - it is enabled by default, but can be disabled by passing `--no-default-features` to cargo. We could specically check for Windows 7 and disable the feature flag automatically, but I think it's better for this check to be done by the crossterm crate, since it's the one that actually knows about the underlying terminal. To disable the feature flag in an application that supports Windows 7, add the following to your Cargo.toml: ```toml ratatui = { version = "0.24.0", default-features = false, features = ["crossterm"] } ``` Fixes https://github.com/ratatui-org/ratatui/issues/555
-
c3155a2 (barchart) Add horizontal labels(#518)
Labels were missed in the initial implementation of the horizontal mode for the BarChart widget. This adds them. Fixes https://github.com/ratatui-org/ratatui/issues/499
-
c9b8e7c (barchart) Render value labels with unicode correctly (#515)
An earlier change introduced a bug where the width of value labels with unicode characters was incorrectly using the string length in bytes instead of the unicode character count. This reverts the earlier change.
-
c8ab2d5 (chart) Use graph style for top line (#462)
A bug in the rendering caused the top line of the chart to be rendered using the style of the chart, instead of the dataset style. This is fixed by only setting the style for the width of the text, and not the entire row.
-
0c7d547 (docs) Don't fail rustdoc due to termion (#503)
Windows cannot compile termion, so it is not included in the docs. Rustdoc will fail if it cannot find a link, so the docs fail to build on windows. This replaces the link to TermionBackend with one that does not fail during checks. Fixes https://github.com/ratatui-org/ratatui/issues/498
-
0c52ff4 (gauge) Fix gauge widget colors (#572)
The background colors of the gauge had a workaround for the issue we had with VHS / TTYD rendering the background color of the gauge. This workaround is no longer necessary in the updated versions of VHS / TTYD. Fixes https://github.com/ratatui-org/ratatui/issues/501
-
11076d0 (rect) Fix arithmetic overflow edge cases (#543)
Fixes https://github.com/ratatui-org/ratatui/issues/258
-
21303f2 (rect) Prevent overflow in inner() and area() (#523)
-
ebd3680 (stylize) Add Stylize impl for String (#466) [breaking]
Although the `Stylize` trait is already implemented for `&str` which extends to `String`, it is not implemented for `String` itself. This commit adds an impl of Stylize that returns a Span<'static> for `String` so that code can call Stylize methods on temporary `String`s. E.g. the following now compiles instead of failing with a compile error about referencing a temporary value: let s = format!("hello {name}!", "world").red(); BREAKING CHANGE: This may break some code that expects to call Stylize methods on `String` values and then use the String value later. This will now fail to compile because the String is consumed by set_style instead of a slice being created and consumed. This can be fixed by cloning the `String`. E.g.: let s = String::from("hello world"); let line = Line::from(vec![s.red(), s.green()]); // fails to compile let line = Line::from(vec![s.clone().red(), s.green()]); // works Fixes https://discord.com/channels/1070692720437383208/1072907135664529508/1148229700821450833

2fd85af (barchart) Simplify internal implementation (#544)
Replace `remove_invisible_groups_and_bars` with `group_ticks` `group_ticks` calculates the visible bar length in ticks. (A cell contains 8 ticks). It is used for 2 purposes: 1. to get the bar length in ticks for rendering 2. since it delivers only the values of the visible bars, If we zip these values with the groups and bars, then we will filter out the invisible groups and bars

Contributors
Thank you so much to everyone that contributed to this release!
Here is the list of contributors who have contributed to ratatui
for the first time!
v0.23.0 - 2023-08-28
We are thrilled to release the new version of ratatui
🐭, the official successor* of tui-rs
.
In this version, we improved the existing widgets such as Barchart
and Scrollbar
. We also made improvmements in the testing/internal APIs to provide a smoother testing/development experience. Additionally, we have addressed various bugs and implemented enhancements.
Here is a blog post that highlights the new features and breaking changes along with a retrospective about the project: https://blog.orhun.dev/ratatui-0-23-0
Features
-
(barchart) Add direction attribute. (horizontal bars support) (#325) (0dca6a6)
* feat(barchart): Add direction attribute Enable rendering the bars horizontally. In some cases this allow us to make more efficient use of the available space.
-
(cell) Add voluntary skipping capability for sixel (#215) (e4bcf78)
> Sixel is a bitmap graphics format supported by terminals. > "Sixel mode" is entered by sending the sequence ESC+Pq. > The "String Terminator" sequence ESC+\ exits the mode. The graphics are then rendered with the top left positioned at the cursor position. It is actually possible to render sixels in ratatui with just `buf.get_mut(x, y).set_symbol("^[Pq ... ^[\")`. But any buffer covering the "image area" will overwrite the graphics. This is most likely the same buffer, even though it consists of empty characters `' '`, except for the top-left character that starts the sequence. Thus, either the buffer or cells must be specialized to avoid drawing over the graphics. This patch specializes the `Cell` with a `set_skip(bool)` method, based on James' patch: https://github.com/TurtleTheSeaHobo/tui-rs/tree/sixel-support I unsuccessfully tried specializing the `Buffer`, but as far as I can tell buffers get merged all the way "up" and thus skipping must be set on the Cells. Otherwise some kind of "skipping area" state would be required, which I think is too complicated. Having access to the buffer now it is possible to skip all cells but the first one which can then `set_symbol(sixel)`. It is up to the user to deal with the graphics size and buffer area size. It is possible to get the terminal's font size in pixels with a syscall. An image widget for ratatui that uses this `skip` flag is available at https://github.com/benjajaja/ratatu-image.
-
(list) Add option to always allocate the "selection" column width (#394) (4d70169)
* feat(list): add option to always allocate the "selection" column width Before this option was available, selecting a item in a list when nothing was selected previously made the row layout change (the same applies to unselecting) by adding the width of the "highlight symbol" in the front of the list, this option allows to configure this behavior. * style: change "highlight_spacing" doc comment to use inline code-block for reference
-
(release) Add automated nightly releases (#359) (aad164a)
* feat(release): add automated nightly releases * refactor(release): rename the alpha workflow * refactor(release): simplify the release calculation
-
(scrollbar) Add optional track symbol (#360) (1727fa5) [breaking]
The track symbol is now optional, simplifying composition with other widgets.
-
(table) Add support for line alignment in the table widget (#392) (7748720)
* feat(table): enforce line alignment in table render * test(table): add table alignment render test
-
(widgets::table) Add option to always allocate the "selection" constraint (#375) (f63ac72)
* feat(table): add option to configure selection layout changes Before this option was available, selecting a row in the table when no row was selected previously made the tables layout change (the same applies to unselecting) by adding the width of the "highlight symbol" in the front of the first column, this option allows to configure this behavior. * refactor(table): refactor "get_columns_widths" to return (x, width) and "render" to make use of that * refactor(table): refactor "get_columns_widths" to take in a selection_width instead of a boolean also refactor "render" to make use of this change * fix(table): rename "highlight_set_selection_space" to "highlight_spacing" * style(table): apply doc-comment suggestions from code review
-
(uncategorized) Expand serde attributes for
TestBuffer
(#389) (57ea871) -
(uncategorized) Add weak constraints to make rects closer to each other in size ✨ (#395) (6153371)
Also make `Max` and `Min` constraints MEDIUM strength for higher priority over equal chunks
Bug Fixes
-
(barchart) Empty groups causes panic (#333) (9c95673)
This unlikely to happen, since nobody wants to add an empty group. Even we fix the panic, things will not render correctly. So it is better to just not add them to the BarChart.
-
(block) Fixed title_style not rendered (#349) (#363) (49a82e0)
-
(cargo) Adjust minimum paste version (#348) (8db9fb4)
ratatui is using features that are currently only available in paste 1.0.2; specifying the minimum version to be 1.0 will consequently cause a compilation error if cargo is only able to use a version less than 1.0.2.
-
(example) Fix typo (#337) (daf5890)
the existential feels
-
(layout) Don't leave gaps between chunks (#408) (56455e0)
Previously the layout used the floor of the calculated start and width as the value to use for the split Rects. This resulted in gaps between the split rects. This change modifies the layout to round to the nearest column instead of taking the floor of the start and width. This results in the start and end of each rect being rounded the same way and being strictly adjacent without gaps. Because there is a required constraint that ensures that the last end is equal to the area end, there is no longer the need to fixup the last item width when the fill (as e.g. width = x.99 now rounds to x+1 not x). The colors example has been updated to use Ratio(1, 8) instead of Percentage(13), as this now renders without gaps for all possible sizes, whereas previously it would have left odd gaps between columns.
-
(layout) Ensure left <= right (#410) (f4ed3b7)
The recent refactor missed the positive width constraint
-
(release) Fix the last tag retrieval for alpha releases (#416) (b6b2da5)
-
(release) Set the correct permissions for creating alpha releases (#400) (778c320)
-
(scrollbar) Move symbols to symbols module (#330) (7539f77) [breaking]
The symbols and sets are moved from `widgets::scrollbar` to `symbols::scrollbar`. This makes it consistent with the other symbol sets and allows us to make the scrollbar module private rather than re-exporting it.
-
(table) Fix unit tests broken due to rounding (#419) (dc55211)
The merge of the table unit tests after the rounding layout fix was not rebased correctly, this addresses the broken tests, makes them more concise while adding comments to help clarify that the rounding behavior is working as expected.
-
(uncategorized) Correct minor typos in documentation (#331) (13fb11a)
Refactor
-
(barchart) Reduce some calculations (#430) (fc727df)
Calculating the label_offset is unnecessary, if we just render the group label after rendering the bars. We can just reuse bar_y.
-
(layout) Simplify and doc split() (#405) (de25de0)
* test(layout): add tests for split() * refactor(layout): simplify and doc split() This is mainly a reduction in density of the code with a goal of improving mainatainability so that the algorithm is clear.
-
(layout) Simplify split() function (#396) (5195099)
Removes some unnecessary code and makes the function more readable. Instead of creating a temporary result and mutating it, we just create the result directly from the list of changes.

-
(examples) Add examples readme with gifs (#303) (add578a)
This commit adds a readme to the examples directory with gifs of each example. This should make it easier to see what each example does without having to run it. I modified the examples to fit better in the gifs. Mostly this was just removing the margins, but for the block example I cleaned up the code a bit to make it more readable and changed it so the background bug is not triggered. For the table example, the combination of Min, Length, and Percent constraints was causing the table to panic when the terminal was too small. I changed the example to use the Max constraint instead of the Length constraint. The layout example now shows information about how the layout is constrained on each block (which is now a paragraph with a block).

v0.19.0 - 2022-08-14
Features
- Bump
crossterm
to0.25
v0.18.0 - 2022-04-24
Features
- Update
crossterm
to0.23
v0.17.0 - 2022-01-22
Features
- Add option to
widgets::List
to repeat the highlight symbol for each line of multi-line items (#533). - Add option to control the alignment of
Axis
labels in theChart
widget (#568).
Breaking changes
- The minimum supported rust version is now
1.56.1
.
New default backend and consolidated backend options (#553)
crossterm
is now the default backend. If you are already using thecrossterm
backend, you can simplify your dependency specification inCargo.toml
:
- tui = { version = "0.16", default-features = false, features = ["crossterm"] }
+ tui = "0.17"
If you are using the termion
backend, your Cargo
is now a bit more verbose:
- tui = "0.16"
+ tui = { version = "0.17", default-features = false, features = ["termion"] }
crossterm
has also been bumped to version 0.22
.
Because of their apparent low usage, curses
and rustbox
backends have been removed.
If you are using one of them, you can import their last implementation in your own project:
Canvas labels (#543)
- Labels of the
Canvas
widget are nowtext::Spans
. The signature ofwidgets::canvas::Context::print
has thus been updated:
- ctx.print(x, y, "Some text", Color::Yellow);
+ ctx.print(x, y, Span::styled("Some text", Style::default().fg(Color::Yellow)))
v0.16.0 - 2021-08-01
Features
- Update
crossterm
to0.20
. - Add
From<Cow<str>>
implementation fortext::Text

Breaking changes
New API for the Table widget
The Table
widget got a lot of improvements that should make it easier to work with:
- It should not longer panic when rendered on small areas.
Row
s are now a collection ofCell
s, themselves wrapping aText
. This means you can style the entireTable
, an entireRow
, an entireCell
and rely on the styling capabilities ofText
to get full control over the look of yourTable
.Row
s can have multiple lines.- The header is now optional and is just another
Row
always visible at the top. Row
s can have a bottom margin.- The header alignment is no longer off when an item is selected.
Taking the example of the code in examples/demo/ui.rs
, this is what you may have to change:
let failure_style = Style::default()
.fg(Color::Red)
.add_modifier(Modifier::RAPID_BLINK | Modifier::CROSSED_OUT);
- let header = ["Server", "Location", "Status"];
let rows = app.servers.iter().map(|s| {
let style = if s.status == "Up" {
up_style
} else {
failure_style
};
- Row::StyledData(vec![s.name, s.location, s.status].into_iter(), style)
+ Row::new(vec![s.name, s.location, s.status]).style(style)
});
- let table = Table::new(header.iter(), rows)
+ let table = Table::new(rows)
+ .header(
+ Row::new(vec!["Server", "Location", "Status"])
+ .style(Style::default().fg(Color::Yellow))
+ .bottom_margin(1),
+ )
.block(Block::default().title("Servers").borders(Borders::ALL))
- .header_style(Style::default().fg(Color::Yellow))
.widths(&[
Constraint::Length(15),
Constraint::Length(15),
Here, we had to:
- Change the way we construct
Row
which is no longer anenum
but astruct
. It accepts anything that can be converted to an iterator of things that can be converted to aCell
- The header is no longer a required parameter so we use
Table::header
to set it.Table::header_style
has been removed since the style can be directly set usingRow::style
. In addition, we want to preserve the old margin between the header and the rest of the rows so we add a bottom margin to the header usingRow::bottom_margin
.
You may want to look at the documentation of the different types to get a better understanding:
Fixes
- Fix handling of Non Breaking Space (NBSP) in wrapped text in
Paragraph
widget.
Features
- Add
Style::reset
to create aStyle
resetting all styling properties when applied. - Add an option to render the

- Add
LineGauge
widget which is a more compact variant of the existingGauge
. - Bump
crossterm

v0.10.0 - 2020-07-17
Breaking changes
Easier cursor management
A new method has been added to Frame
called set_cursor
. It lets you specify where the cursor
should be placed after the draw call. Furthermore like any other widgets, if you do not set a cursor
position during a draw call, the cursor is automatically hidden.
For example:
fn draw_input(f: &mut Frame, app: &App) {
if app.editing {
let input_width = app.input.width() as u16;
// The cursor will be placed just after the last character of the input
f.set_cursor((input_width + 1, 0));
} else {
// We are no longer editing, the cursor does not have to be shown, set_cursor is not called and
// thus automatically hidden.
}
}
In order to make this possible, the draw closure takes in input &mut Frame
instead of mut Frame
.
Advanced text styling
It has been reported several times that the text styling capabilities were somewhat limited in many places of the crate. To solve the issue, this release includes a new set of text primitives that are now used by a majority of widgets to provide flexible text styling.
Text
is replaced by the following types:
Span
: a string with a unique style.Spans
: a string with multiple styles.Text
: a multi-lines string with multiple styles.
However, you do not always need this complexity so the crate provides From
implementations to
let you use simple strings as a default and switch to the previous primitives when you need
additional styling capabilities.
For example, the title of a Block
can be set in the following ways:
// A title with no styling
Block::default().title("My title");
// A yellow title
Block::default().title(Span::styled("My title", Style::default().fg(Color::Yellow)));
// A title where "My" is bold and "title" is a simple string
Block::default().title(vec![
Span::styled("My", Style::default().add_modifier(Modifier::BOLD)),
Span::from("title")
]);
Buffer::set_spans
andBuffer::set_span
were added.Paragraph::new
expects an input that can be converted to aText
.Block::title_style
is deprecated.Block::title
expects aSpans
.Tabs
expects a list ofSpans
.Gauge
custom label is now aSpan
.Axis
title and labels areSpans
(as a consequenceChart
no longer has generic bounds).
Incremental styling
Previously Style
was used to represent an exhaustive set of style rules to be applied to an UI
element. It implied that whenever you wanted to change even only one property you had to provide the
complete style. For example, if you had a Block
where you wanted to have a green background and
a title in bold, you had to do the following:
let style = Style::default().bg(Color::Green);
Block::default()
.style(style)
.title("My title")
// Here we reused the style otherwise the background color would have been reset
.title_style(style.modifier(Modifier::BOLD));
In this new release, you may now write this as:
Block::default()
.style(Style::default().bg(Color::Green))
// The style is not overridden anymore, we simply add new style rule for the title.
.title(Span::styled("My title", Style::default().add_modifier(Modifier::BOLD)))
In addition, the crate now provides a method patch
to combine two styles into a new set of style
rules:
let style = Style::default().modifier(Modifier::BOLD);
let style = style.patch(Style::default().add_modifier(Modifier::ITALIC));
// style.modifier == Modifier::BOLD | Modifier::ITALIC, the modifier has been enriched not overridden
Style::modifier
has been removed in favor ofStyle::add_modifier
andStyle::remove_modifier
.Buffer::set_style
has been added.Buffer::set_background
is deprecated.BarChart::style
no longer set the style of the bars. UseBarChart::bar_style
in replacement.Gauge::style
no longer set the style of the gauge. UseGauge::gauge_style
in replacement.
List with item on multiple lines
The List
widget has been refactored once again to support items with variable heights and complex
styling.
List::new
expects an input that can be converted to aVec<ListItem>
whereListItem
is a wrapper around the item content to provide additional styling capabilities.ListItem
contains aText
.List::items
has been removed.
// Before
let items = vec![
"Item1",
"Item2",
"Item3"
];
List::default().items(items.iters());
// After
let items = vec![
ListItem::new("Item1"),
ListItem::new("Item2"),
ListItem::new("Item3"),
];
List::new(items);
See the examples for more advanced usages.
More wrapping options
Paragraph::wrap
expects Wrap
instead of bool
to let users decided whether they want to trim
whitespaces when the text is wrapped.
// before
Paragraph::new(text).wrap(true)
// after
Paragraph::new(text).wrap(Wrap { trim: true }) // to have the same behavior
Paragraph::new(text).wrap(Wrap { trim: false }) // to use the new behavior
Horizontal scrolling in paragraph
You can now scroll horizontally in Paragraph
. The argument of Paragraph::scroll
has thus be
changed from u16
to (u16, u16)
.
Features
Serialization of style
You can now serialize and de-serialize Style
using the optional serde
feature.

v0.9.1 - 2020-04-16
Bug Fixes
- The
List
widget now takes into account the width of thehighlight_symbol
when calculating the total width of its items. It prevents items to overflow outside of the widget area.
v0.9.0 - 2020-04-14
Features
- Introduce stateful widgets, i.e widgets that can take advantage of keeping some state around between two draw calls (#210 goes a bit more into the details).
- Allow a
Table
row to be selected.
// State initialization
let mut state = TableState::default();
// In the terminal.draw closure
let header = ["Col1", "Col2", "Col"];
let rows = [
Row::Data(["Row11", "Row12", "Row13"].into_iter())
];
let table = Table::new(header.into_iter(), rows.into_iter());
f.render_stateful_widget(table, area, &mut state);
// In response to some event:
state.select(Some(1));
-
Add a way to choose the type of border used to draw a block. You can now choose from plain, rounded, double and thick lines.
-
Add a
graph_type
property on theDataset
of aChart
widget. By default it will beScatter
where the points are drawn as is. An other option isLine
where a line will be draw between each consecutive points of the dataset. -
Style methods are now const, allowing you to initialize const
Style
objects. -
Improve control over whether the legend in the
Chart
widget is shown or not. You can now set custom constraints usingChart::hidden_legend_constraints
. -
Add
Table::header_gap
to add some space between the header and the first row. -
Remove
log
from the dependencies -
Add a way to use a restricted set of unicode symbols in several widgets to improve portability in exchange of a degraded output. (see
BarChart::bar_set
,Sparkline::bar_set
andCanvas::marker
). You can check how the--enhanced-graphics
flag is used in the demos.
Breaking Changes
Widget::render
has been deleted. You should now useFrame::render_widget
to render a widget on the correspondingFrame
. This makes theWidget
implementation totally decoupled from theFrame
.
// Before
Block::default().render(&mut f, size);
// After
let block = Block::default();
f.render_widget(block, size);
Widget::draw
has been renamed toWidget::render
and the signature has been updated to reflect that widgets are consumable objects. Thus the method takesself
instead of&mut self
.
// Before
impl Widget for MyWidget {
fn draw(&mut self, area: Rect, buf: &mut Buffer) {
}
}
/// After
impl Widget for MyWidget {
fn render(self, arera: Rect, buf: &mut Buffer) {
}
}
Widget::background
has been replaced byBuffer::set_background
// Before
impl Widget for MyWidget {
fn render(self, arera: Rect, buf: &mut Buffer) {
self.background(area, buf, self.style.bg);
}
}
// After
impl Widget for MyWidget {
fn render(self, arera: Rect, buf: &mut Buffer) {
buf.set_background(area, self.style.bg);
}
}
-
Update the
Shape
trait for objects that can be draw on aCanvas
widgets. Instead of returning an iterator over its points, aShape
is given aPainter
object that provides apaint
as well as aget_point
method. This gives theShape
more information about the surface it will be drawn to. In particular, this change allows theLine
shape to use a more precise and efficient drawing algorithm (Bresenham's line algorithm). -
SelectableList
has been deleted. You can now take advantage of the associatedListState
of theList
widget to select an item.
// Before
List::new(&["Item1", "Item2", "Item3"])
.select(Some(1))
.render(&mut f, area);
// After
// State initialization
let mut state = ListState::default();
// In the terminal.draw closure
let list = List::new(&["Item1", "Item2", "Item3"]);
f.render_stateful_widget(list, area, &mut state);
// In response to some events
state.select(Some(1));
widgets::Marker
has been moved tosymbols::Marker

- Add support for multiple modifiers on the same
Style
by changingModifier
from an enum to a bitflags struct.
So instead of writing:
let style = Style::default().add_modifier(Modifier::Italic);
one should use:
let style = Style::default().add_modifier(Modifier::ITALIC);
// or
let style = Style::default().add_modifier(Modifier::ITALIC | Modifier::BOLD);

Features
show_cursor
is called whenTerminal
is dropped if the cursor is hidden.
v0.3.0-beta.2 - 2018-09-23
Breaking Changes
- Remove custom
termion
backends. This is motivated by the fact thattermion
structs are meant to be combined/wrapped to provide additional functionalities to the terminal (e.g AlternateScreen, Mouse support, ...). Thus providing exclusive types do not make a lot of sense and give a false hint that additional features cannot be used together. The recommended approach is now to create your own version ofstdout
:
let stdout = io::stdout().into_raw_mode()?;
let stdout = MouseTerminal::from(stdout);
let stdout = AlternateScreen::from(stdout);
and then to create the corresponding termion
backend:
let backend = TermionBackend::new(stdout);
The resulting code is more verbose but it works with all combinations of
additional termion
features.
