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
The `Spans` type (plural, not singular) was replaced with a more ergonomic `Line` type
in Ratatui v0.21.0 and marked deprecated byt left for backwards compatibility. This is now
removed.
- `Line` replaces `Spans`
- `Buffer::set_line` replaces `Buffer::set_spans`
This allows writing unit tests without having to call set_style on the
expected buffer.
E.g.:
```rust
use crate::style::Stylize;
let mut buf = Buffer::empty(Rect::new(0, 0, 10, 10));
buf.set_string(0, 0, "foo", Style::new().red());
buf.set_string(0, 1, "bar", Style::new().blue());
assert_eq!(buf, Buffer::with_lines(vec!["foo".red(), "bar".blue()]));
```
Inspired by https://github.com/ratatui-org/ratatui/issues/493#issuecomment-1714844468
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.

* feat(barchart): Add direction attribute
Enable rendring the bars horizontally. In some cases this allow us to
make more efficient use of the available space.

* feat(barchart)!: render the group labels depending on the alignment
This is a breaking change, since the alignment by default is set to
Left and the group labels are always rendered in the center.

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.
* 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
* 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

* fix(title): remove default alignment and position
* test(block): add test cases for alignment
* test(block): extend the unit tests for block title alignment
* feat(stylize): allow all widgets to be styled
- Add styled impl to:
- Barchart
- Chart (including Axis and Dataset),
- Guage and LineGuage
- List and ListItem
- Sparkline
- Table, Row, and Cell
- Tabs
- Style
- Allow modifiers to be removed (e.g. .not_italic())
- Allow .bg() to recieve Into<Color>
- Made shorthand methods consistent with modifier names (e.g. dim() not
dimmed() and underlined() not underline())
- Simplify integration tests
- Add doc comments
- Simplified stylize macros with https://crates.io/crates/paste
* build: run clippy before tests
Runny clippy first means that we fail fast when there is an issue that
can easily be fixed rather than having to wait 30-40s for the failure
for now the value is converted to a string and then printed. in many
cases the values are too wide or double values. so it make sense
to set a custom value text instead of the default behavior.
this patch suggests to add a method
"fn text_value(mut self, text_value: String)"
to the Bar, which allows to override the value printed in the bar

Example: to show the revenue of different companies:

└────────────────────────┘
new structs are introduced: Group and Bar.
the data function is modified to accept "impl Into<Group<'a>>".
a new function "group_gap" is introduced to set the gap between each group

bar. This commit centers the labels under the bar.

* fix(gauge): render gauge with unicode correctly
Gauge now correctly renders a block rather than a space when in unicode mode.
* docs: update demo.gif
- remove existing gif
- upload using VHS (https://github.com/charmbracelet/vhs)
- add instructions to RELEASE.md
- link new gif in README
This is an opinionated default that helps avoid horizontal scrolling.
100 is the most common width on github rust projects and works well for
displaying code on a 16in macbook pro.
`Paragraph` now supports rendering each line in the paragraph with a
different alignment (Center, Left and Right) rather than the entire
paragraph being aligned the same. Each line either overrides the
paragraph's alignment or inherits it if the line's alignment is
unspecified.
- Adds `alignment` field to `Line` and builder methods on `Line` and
`Span`
- Updates reflow module types to be line oriented rather than symbol
oriented to take account of each lines alignment
- Adds unit tests to `Paragraph` to fully capture the existing and new
behavior

Adds a `border!` macro that takes TOP, BOTTOM, LEFT, RIGHT, and ALL and
returns a Borders object. An empty `border!()` call returns
Borders::NONE
This is gated behind a `macros` feature flag to ensure short build
times. To enable, add the following to your `Cargo.toml`:
```toml
ratatui = { version = 0.21.0, features = ["macros"] }

* refactor: add Line type to replace Spans
`Line` is a significantly better name over `Spans` as the plural causes
confusion and the type really is a representation of a line of text made
up of spans.
This is a backwards compatible version of the approach from
https://github.com/tui-rs-revival/ratatui/pull/175
There is a significant amount of code that uses the Spans type and
methods, so instead of just renaming it, we add a new type and replace
parameters that accepts a `Spans` with a parameter that accepts
`Into<Line>`.
Note that the examples have been intentionally left using `Spans` in
this commit to demonstrate the compiler warnings that will be emitted in
existing code.
Implementation notes:
- moves the Spans code to text::spans and publicly reexports on the text
module. This makes the test in that module only relevant to the Spans
type.
- adds a line module with a copy of the code and tests from Spans with a
single addition: `impl<'a> From<Spans<'a>> for Line<'a>`
- adds tests for `Spans` (created and checked before refactoring)
- adds the same tests for `Line`
- updates all widget methods that accept and store Spans to instead
store `Line` and accept `Into<Line>`
* refactor: move text::Masked to text::masked::Masked
Re-exports the Masked type at text::Masked
* refactor: replace Spans with Line in tests/examples/docs
Fixes issue #680. Handles the case where a list item is created with an empty string, which is not split by the lines iterator.
