* 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:🗜️:case_01_inside ... ok
test layout::rect::tests:🗜️:case_02_up_left ... ok
test layout::rect::tests:🗜️:case_04_up_right ... ok

test layout::rect::tests:🗜️:case_09_down_right ... ok
test layout::rect::tests:🗜️:case_10_too_wide ... ok
test layout::rect::tests:🗜️:case_11_too_tall ... ok
test layout::rect::tests:🗜️:case_12_too_large ... ok
* fix: less ambiguous docs for this / other rect
* fix: move rstest to dev deps
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.

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"] }
```

* docs: make library and README consistent
Generate the bulk of the README from the library documentation, so that
they are consistent using cargo-rdme.
- Removed the Contributors section, as it is redundant with the github
contributors list.
- Removed the info about the other backends and replaced it with a
pointer to the documentation.
- add docsrs example, vhs tape and images that will end up in the README
Fixes: https://github.com/ratatui-org/ratatui/issues/512
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`
* docs(lib): extract feature documentation from Cargo.toml
* chore(deps): make `document-features` optional dependency
* docs(lib): document the serde feature from features section
* 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.
* chore(toolchain)!: bump msrv to 1.67
BREAKING_CHANGE: The msrv is now `1.67`
* docs(readme): update the MSRV notice

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.
* 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
Before this change, it wasn't possible to build all features and all
targets at the same time, which prevents rust-analyzer from working
for the whole project.
Adds a bacon.toml file to the project, which is used by bacon
https://dystroy.org/bacon/
Configures docs.rs to show the feature flags that are necessary to
make modules / types / functions available.
Represents a scrollbar widget that renders a track, thumb and arrows
either horizontally or vertically. State is kept in ScrollbarState, and
passed as a parameter to the render function.
To run the benchmarks:
cargo bench
And then open the generated `target/criterion/report/index.html` in a
browser.
- add the BSD 2 clause and ISC licenses to the `cargo deny` allowed
licenses list (as a transitive dependency of the `fakeit` crate).
- remove the WTFPL license from the `cargo deny` allowed licenses list
as it is unused and causes a warning when running the check.
BREAKING CHANGE: The serde representation of bitflags has changed. Any
existing serialized types that have Borders or Modifiers will need to be
re-serialized. This is documented in the bitflags changelog.
https://github.com/bitflags/bitflags/blob/main/CHANGELOG.md#200-rc2
- Reformat summary info
- Add badges for dependencies, discord, license
- point existing badges to shields.io
- add Table of Contents
- tweaked installation instructions to show instructions for new and
existing crates
- moved fork status lower
- chop lines generally to 100 limit
- add a quickstart based on a simplified hello_world example
- added / updated some internal links to point locally
- removed some details to simplify the readme (e.g. tick-rate)
- reordered widgets and pointed these at the widget docs
- adds a hello_world example that has just the absolute basic code
necessary to run a ratatui app. This includes some comments that help
guide the user towards other approaches and considerations for a real
world app.
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"] }
```

* build: bump MSRV to 1.65
The latest version of the time crate requires Rust 1.65.0
```
cargo +1.64.0-x86_64-apple-darwin test --no-default-features \
--features serde,crossterm,all-widgets --lib --tests --examples
error: package `time v0.3.21` cannot be built because it requires rustc
1.65.0 or newer, while the currently active rustc version is 1.64.0
```
* feat(backend): add termwiz backend and demo
* ci(termwiz): add termwiz to makefile.toml

Also fixes several clippy warnings added in 1.63/1.65. Although these
have been since moved to nursery / pedantic, it doesn't hurt to fix
these issues as part of this change:

- https://rust-lang.github.io/rust-clippy/master/index.html#bool_to_int_with_if (pedantic)
