chore: remove conventional commit check for PR (#950 )

This removes conventional commit check for PRs. Since we use the PR title and description this is useless. It fails a lot of time and we ignore it. IMPORTANT NOTE: This does **not** mean Ratatui abandons conventional commits. This only relates to commits in PRs.

+
+## [v0.26.0](https://github.com/ratatui-org/ratatui/releases/tag/v0.26.0)
+
+### `Flex::Start` is the new default flex mode for `Layout`
+
+[#881]: https://github.com/ratatui-org/ratatui/pull/881
+
+Previously, constraints would stretch to fill all available space, violating constraints if 
+necessary.
+
+With v0.26.0, `Flex` modes are introduced and the default is `Flex::Start`, which will align 
+areas associated with constraints to be beginning of the area. With v0.26.0, additionally, 
+`Min` constraints grow to fill excess space. These changes will allow users to build layouts 
+more easily.
+
+With v0.26.0, users will most likely not need to change what constraints they use to create 
+existing layouts with `Flex::Start`. However, to get old behavior, use `Flex::Legacy`.
+
+```diff
+- let rects = Layout::horizontal([Length(1), Length(2)]).split(area);
+// becomes
+ let rects = Layout::horizontal([Length(1), Length(2)]).flex(Flex::Legacy).split(area);
+```
+
+### `Table::new()` now accepts `IntoIterator<Item: Into<Row<'a>>>` ([#774])
+
+[#774]: https://github.com/ratatui-org/ratatui/pull/774
+
+Previously, `Table::new()` accepted `IntoIterator<Item=Row<'a>>`.  The argument change to
+`IntoIterator<Item: Into<Row<'a>>>`, This allows more flexible types from calling scopes, though it
+can some break type inference in the calling scope for empty containers.
+
+This can be resolved either by providing an explicit type (e.g. `Vec::<Row>::new()`), or by using
+`Table::default()`.
+
+```diff
+- let table = Table::new(vec![], widths);
+// becomes
+ let table = Table::default().widths(widths);
+```
+
+### `Tabs::new()` now accepts `IntoIterator<Item: Into<Line<'a>>>` ([#776])
+
+[#776]: https://github.com/ratatui-org/ratatui/pull/776
+
+Previously, `Tabs::new()` accepted `Vec<T>` where `T: Into<Line<'a>>`.  This allows more flexible
+types from calling scopes, though it can break some type inference in the calling scope.
+
+This typically occurs when collecting an iterator prior to calling `Tabs::new`, and can be resolved
+by removing the call to `.collect()`.
+
+```diff
+- let tabs = Tabs::new((0.3).map(|i| format!("{i}")).collect());
+// becomes
+ let tabs = Tabs::new((0.3).map(|i| format!("{i}")));
+```
+
+### Table::default() now sets segment_size to None and column_spacing to ([#751])
+
+[#751]: https://github.com/ratatui-org/ratatui/pull/751
+
+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.
+
+To use the previous default values, call `table.segment_size(Default::default())` and
+`table.column_spacing(0)`.
+
+### `patch_style` & `reset_style` now consumes and returns `Self` ([#754])
+
+[#754]: https://github.com/ratatui-org/ratatui/pull/754
+
+Previously, `patch_style` and `reset_style` in `Text`, `Line` and `Span` were using a mutable
+reference to `Self`. To be more consistent with the rest of `ratatui`, which is using fluent
+setters, these now take ownership of `Self` and return it.
+
+The following example shows how to migrate for `Line`, but the same applies for `Text` and `Span`.
+
+```diff
+- let mut line = Line::from("foobar");
+- line.patch_style(style);
+// becomes
+ let line = Line::new("foobar").patch_style(style);
+```
+
+### Remove deprecated `Block::title_on_bottom` ([#757])
+
+[#757]: https://github.com/ratatui-org/ratatui/pull/757
+
+`Block::title_on_bottom` was deprecated in v0.22. Use `Block::title` and `Title::position` instead.
+
+```diff
+- block.title("foobar").title_on_bottom();
+ block.title(Title::from("foobar").position(Position::Bottom));
+```
+
+### `Block` style methods cannot be used in a const context ([#720])
+
+[#720]: https://github.com/ratatui-org/ratatui/pull/720
+
+Previously the `style()`, `border_style()` and `title_style()` methods could be used to create a
+`Block` in a constant context. These now accept `Into<Style>` instead of `Style`. These methods no
+longer can be called from a constant context.
+
+### `Line` now has a `style` field that applies to the entire line ([#708])
+
+[#708]: https://github.com/ratatui-org/ratatui/pull/708
+
+Previously the style of a `Line` was stored in the `Span`s that make up the line. Now the `Line`
+itself has a `style` field, which can be set with the `Line::styled` method. Any code that creates
+`Line`s using the struct initializer instead of constructors will fail to compile due to the added
+field. This can be easily fixed by adding `..Default::default()` to the field list or by using a
+constructor method (`Line::styled()`, `Line::raw()`) or conversion method (`Line::from()`).
+
+Each `Span` contained within the line will no longer have the style that is applied to the line in
+the `Span::style` field.
+
+```diff
+  let line = Line {
+      spans: vec!["".into()],
+      alignment: Alignment::Left,
+     ..Default::default()
+  };
+
+  // or
+
+  let line = Line::raw(vec!["".into()])
+      .alignment(Alignment::Left);
+```
+
+## [v0.25.0](https://github.com/ratatui-org/ratatui/releases/tag/v0.25.0)
+
+### Removed `Axis::title_style` and `Buffer::set_background` ([#691])
+
+[#691]: https://github.com/ratatui-org/ratatui/pull/691
+
+These items were deprecated since 0.10.
+
+- You should use styling capabilities of [`text::Line`] given as argument of [`Axis::title`]
+  instead of `Axis::title_style`
+- You should use styling capabilities of [`Buffer::set_style`] instead of `Buffer::set_background`
+
+[`text::Line`]: https://docs.rs/ratatui/latest/ratatui/text/struct.Line.html
+[`Axis::title`]: https://docs.rs/ratatui/latest/ratatui/widgets/struct.Axis.html#method.title
+[`Buffer::set_style`]: https://docs.rs/ratatui/latest/ratatui/buffer/struct.Buffer.html#method.set_style
+
+### `List::new()` now accepts `IntoIterator<Item = Into<ListItem<'a>>>` ([#672])
+
+[#672]: https://github.com/ratatui-org/ratatui/pull/672
+
+Previously `List::new()` took `Into<Vec<ListItem<'a>>>`. This change will throw a compilation
+error for `IntoIterator`s with an indeterminate item (e.g. empty vecs).
+
+E.g.
+
+```diff
+- let list = List::new(vec![]);
+// becomes
+ let list = List::default();
+```
+
+### The default `Tabs::highlight_style` is now `Style::new().reversed()` ([#635])
+
+[#635]: https://github.com/ratatui-org/ratatui/pull/635
+
+Previously the default highlight style for tabs was `Style::default()`, which meant that a `Tabs`
+widget in the default configuration would not show any indication of the selected tab.
+
+### The default `Tabs::highlight_style` is now `Style::new().reversed()` ([#635])
+
+Previously the default highlight style for tabs was `Style::default()`, which meant that a `Tabs`
+widget in the default configuration would not show any indication of the selected tab.
+
+### `Table::new()` now requires specifying the widths of the columns ([#664])
+
+[#664]: https://github.com/ratatui-org/ratatui/pull/664
+
+Previously `Table`s could be constructed without widths. In almost all cases this is an error.
+A new widths parameter is now mandatory on `Table::new()`. Existing code of the form:
+
+```diff
+- Table::new(rows).widths(widths)
+```
+
+Should be updated to:
+
+```diff
+ Table::new(rows, widths)
+```
+
+For ease of automated replacement in cases where the amount of code broken by this change is large
+or complex, it may be convenient to replace `Table::new` with `Table::default().rows`.
+
+```diff
+- Table::new(rows).block(block).widths(widths);
+// becomes
+ Table::default().rows(rows).widths(widths)
+```
+
+### `Table::widths()` now accepts `IntoIterator<Item = AsRef<Constraint>>` ([#663])
+
+[#663]: https://github.com/ratatui-org/ratatui/pull/663
+
+Previously `Table::widths()` took a slice (`&'a [Constraint]`). This change will introduce clippy
+`needless_borrow` warnings for places where slices are passed to this method. To fix these, remove
+the `&`.
+
+E.g.
+
+```diff
+- let table = Table::new(rows).widths(&[Constraint::Length(1)]);
+// becomes
+ let table = Table::new(rows, [Constraint::Length(1)]);
+```
+
+### Layout::new() now accepts direction and constraint parameters ([#557])
+
+[#557]: https://github.com/ratatui-org/ratatui/pull/557
+
+Previously layout new took no parameters. Existing code should either use `Layout::default()` or
+the new constructor.
+
+```rust
+let layout = layout::new()
+  .direction(Direction::Vertical)
+  .constraints([Constraint::Min(1), Constraint::Max(2)]);
+// becomes either
+let layout = layout::default()
+  .direction(Direction::Vertical)
+  .constraints([Constraint::Min(1), Constraint::Max(2)]);
+// or
+let layout = layout::new(Direction::Vertical, [Constraint::Min(1), Constraint::Max(2)]);
+```
+
+## [v0.24.0](https://github.com/ratatui-org/ratatui/releases/tag/v0.24.0)
+
+### ScrollbarState field type changed from `u16` to `usize` ([#456])
+
+[#456]: https://github.com/ratatui-org/ratatui/pull/456
+
+In order to support larger content lengths, the `position`, `content_length` and
+`viewport_content_length` methods on `ScrollbarState` now take `usize` instead of `u16`
+
+### `BorderType::line_symbols` renamed to `border_symbols` ([#529])
+
+[#529]: https://github.com/ratatui-org/ratatui/issues/529
+
+Applications can now set custom borders on a `Block` by calling `border_set()`. The
+`BorderType::line_symbols()` is renamed to `border_symbols()` and now returns a new struct
+`symbols::border::Set`. E.g.:
+
+```diff
+- let line_set: symbols::line::Set = BorderType::line_symbols(BorderType::Plain);
+// becomes
+ let border_set: symbols::border::Set = BorderType::border_symbols(BorderType::Plain);
+```
+
+### Generic `Backend` parameter removed from `Frame` ([#530])
+
+[#530]: https://github.com/ratatui-org/ratatui/issues/530
+
+`Frame` is no longer generic over Backend. Code that accepted `Frame<Backend>` will now need to
+accept `Frame`. To migrate existing code, remove any generic parameters from code that uses an
+instance of a Frame. E.g.:
+
+```diff
+- fn ui<B: Backend>(frame: &mut Frame<B>) { ... }
+// becomes
+ fn ui(frame: Frame) { ... }
+```
+
+### `Stylize` shorthands now consume rather than borrow `String` ([#466])
+
+[#466]: https://github.com/ratatui-org/ratatui/issues/466
+
+In order to support using `Stylize` shorthands (e.g. `"foo".red()`) on temporary `String` values, a
+new implementation of `Stylize` was added that returns a `Span<'static>`. This causes the value to
+be consumed rather than borrowed. Existing code that expects to use the string after a call will no
+longer compile. E.g.
+
+```diff
+- let s = String::new("foo");
+- let span1 = s.red();
+- let span2 = s.blue(); // will no longer compile as s is consumed by the previous line
+// becomes
+ let span1 = s.clone().red();
+ let span2 = s.blue();
+```
+
+### Deprecated `Spans` type removed (replaced with `Line`) ([#426])
+
+[#426]: https://github.com/ratatui-org/ratatui/issues/426
+
+`Spans` was replaced with `Line` in 0.21.0. `Buffer::set_spans` was replaced with
+`Buffer::set_line`.
+
+```diff
+- let spans = Spans::from(some_string_str_span_or_vec_span);
+- buffer.set_spans(0, 0, spans, 10);
+// becomes
+ let line - Line::from(some_string_str_span_or_vec_span);
+ buffer.set_line(0, 0, line, 10);
+```
+
+## [v0.23.0](https://github.com/ratatui-org/ratatui/releases/tag/v0.23.0)
+
+### `Scrollbar::track_symbol()` now takes an `Option<&str>` instead of `&str` ([#360])
+
+[#360]: https://github.com/ratatui-org/ratatui/issues/360
+
+The track symbol of `Scrollbar` is now optional, this method now takes an optional value.
+
+```diff
+- let scrollbar = Scrollbar::default().track_symbol("|");
+// becomes
+ let scrollbar = Scrollbar::default().track_symbol(Some("|"));
+```
+
+### `Scrollbar` symbols moved to `symbols::scrollbar` and `widgets::scrollbar` module is private ([#330])
+
+[#330]: https://github.com/ratatui-org/ratatui/issues/330
+
+The symbols for defining scrollbars have been moved to the `symbols` module from the
+`widgets::scrollbar` module which is no longer public. To update your code update any imports to the
+new module locations. E.g.:
+
+```diff
+- use ratatui::{widgets::scrollbar::{Scrollbar, Set}};
+// becomes
+ use ratatui::{widgets::Scrollbar, symbols::scrollbar::Set}
+```
+
+### MSRV updated to 1.67 ([#361])
+
+[#361]: https://github.com/ratatui-org/ratatui/issues/361
+
+The MSRV of ratatui is now 1.67 due to an MSRV update in a dependency (`time`).
+
+## [v0.22.0](https://github.com/ratatui-org/ratatui/releases/tag/v0.22.0)
+
+### bitflags updated to 2.3 ([#205])
+
+[#205]: https://github.com/ratatui-org/ratatui/issues/205
+
+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)..
+
+## [v0.21.0](https://github.com/ratatui-org/ratatui/releases/tag/v0.21.0)
+
+### MSRV is 1.65.0 ([#171])
+
+[#171]: https://github.com/ratatui-org/ratatui/issues/171
+
+The minimum supported rust version is now 1.65.0.
+
+### `Terminal::with_options()` stabilized to allow configuring the viewport ([#114])
+
+[#114]: https://github.com/ratatui-org/ratatui/issues/114
+
+In order to support inline viewports, the unstable method `Terminal::with_options()` was stabilized
+and `ViewPort` was changed from a struct to an enum.
+
+```diff
+let terminal = Terminal::with_options(backend, TerminalOptions {
+-    viewport: Viewport::fixed(area),
+});
+// becomes
+let terminal = Terminal::with_options(backend, TerminalOptions {
+    viewport: Viewport::Fixed(area),
+});
+```
+
+### Code that binds `Into<Text<'a>>` now requires type annotations ([#168])
+
+[#168]: https://github.com/ratatui-org/ratatui/issues/168
+
+A new type `Masked` was introduced that implements `From<Text<'a>>`. This causes any code that did
+previously did not need to use type annotations to fail to compile. To fix this, annotate or call
+to_string() / to_owned() / as_str() on the value. E.g.:
+
+```diff
+- let paragraph = Paragraph::new("".as_ref());
+// becomes
+ let paragraph = Paragraph::new("".as_str());
+```
+
+### `Marker::Block` now renders as a block rather than a bar character ([#133])
+
+[#133]: https://github.com/ratatui-org/ratatui/issues/133
+
+Code using the `Block` marker that previously rendered using a half block character (`'▀'``) now
+renders using the full block character (`'█'`). A new marker variant`Bar` is introduced to replace
+the existing code.
+
+```diff
+- let canvas = Canvas::default().marker(Marker::Block);
+// becomes
+ let canvas = Canvas::default().marker(Marker::Bar);
+```
+
+## [v0.20.0](https://github.com/ratatui-org/ratatui/releases/tag/v0.20.0)
+
+v0.20.0 was the first release of Ratatui - versions prior to this were release as tui-rs. See the
+[Changelog](./CHANGELOG.md) for more details.
+
+### MSRV is update to 1.63.0 ([#80])
+
+[#80]: https://github.com/ratatui-org/ratatui/issues/80
+
+The minimum supported rust version is 1.63.0

+### List no longer ignores empty string in items ([#42])
+
+[#42]: https://github.com/ratatui-org/ratatui/issues/42
+
+The following code now renders 3 items instead of 2. Code which relies on the previous behavior will
+need to manually filter empty items prior to display.
+
+```rust
+let items = vec![
+    ListItem::new("line one"),
+    ListItem::new(""),
+    ListItem::new("line four"),
+];

+# Contribution guidelines
+
+First off, thank you for considering contributing to Ratatui.
+
+If your contribution is not straightforward, please first discuss the change you wish to make by
+creating a new issue before making the change, or starting a discussion on
+[discord](https://discord.gg/pMCEU9hNEj).
+
+## Reporting issues
+
+Before reporting an issue on the [issue tracker](https://github.com/ratatui-org/ratatui/issues),
+please check that it has not already been reported by searching for some related keywords. Please
+also check [`tui-rs` issues](https://github.com/fdehau/tui-rs/issues/) and link any related issues
+found.
+
+## Pull requests
+
+All contributions are obviously welcome. Please include as many details as possible in your PR
+description to help the reviewer (follow the provided template). Make sure to highlight changes
+which may need additional attention or you are uncertain about. Any idea with a large scale impact
+on the crate or its users should ideally be discussed in a "Feature Request" issue beforehand.
+
+### Keep PRs small, intentional and focused
+
+Try to do one pull request per change. The time taken to review a PR grows exponential with the size
+of the change. Small focused PRs will generally be much more faster to review. PRs that include both
+refactoring (or reformatting) with actual changes are more difficult to review as every line of the
+change becomes a place where a bug may have been introduced. Consider splitting refactoring /
+reformatting changes into a separate PR from those that make a behavioral change, as the tests help
+guarantee that the behavior is unchanged.
+
+### Code formatting
+
+Run `cargo make format` before committing to ensure that code is consistently formatted with
+rustfmt. Configuration is in [rustfmt.toml](./rustfmt.toml).
+
+### Search `tui-rs` for similar work
+
+The original fork of Ratatui, [`tui-rs`](https://github.com/fdehau/tui-rs/), has a large amount of
+history of the project. Please search, read, link, and summarize any relevant
+[issues](https://github.com/fdehau/tui-rs/issues/),
+[discussions](https://github.com/fdehau/tui-rs/discussions/) and [pull
+requests](https://github.com/fdehau/tui-rs/pulls).
+
+### Use conventional commits
+
+We use [conventional commits](https://www.conventionalcommits.org/en/v1.0.0/) and check for them as
+a lint build step. To help adhere to the format, we recommend to install
+[Commitizen](https://commitizen-tools.github.io/commitizen/). By using this tool you automatically
+follow the configuration defined in [.cz.toml](.cz.toml). Your commit messages should have enough
+information to help someone reading the [CHANGELOG](./CHANGELOG.md) understand what is new just from
+the title. The summary helps expand on that to provide information that helps provide more context,
+describes the nature of the problem that the commit is solving and any unintuitive effects of the
+change. It's rare that code changes can easily communicate intent, so make sure this is clearly
+documented.
+
+### Run CI tests before pushing a PR
+
+We're using [cargo-husky](https://github.com/rhysd/cargo-husky) to automatically run git hooks,
+which will run `cargo make ci` before each push. To initialize the hook  run `cargo test`. If
+`cargo-make` is not installed, it will provide instructions to install it for you. This will ensure
+that your code is formatted, compiles and passes all tests before you push. If you need to skip this
+check, you can use `git push --no-verify`.
+
+### Sign your commits
+
+We use commit signature verification, which will block commits from being merged via the UI unless
+they are signed. To set up your machine to sign commits, see [managing commit signature
+verification](https://docs.github.com/en/authentication/managing-commit-signature-verification/about-commit-signature-verification)
+in GitHub docs.
+
+## Implementation Guidelines
+
+### Setup
+
+Clone the repo and build it using [cargo-make](https://sagiegurari.github.io/cargo-make/)
+
+Ratatui is an ordinary Rust project where common tasks are managed with
+[cargo-make](https://github.com/sagiegurari/cargo-make/). It wraps common `cargo` commands with sane
+defaults depending on your platform of choice. Building the project should be as easy as running
+`cargo make build`.
+
+```shell
+git clone https://github.com/ratatui-org/ratatui.git
+cd ratatui
+cargo make build
+```
+
+### Tests
+
+The [test coverage](https://app.codecov.io/gh/ratatui-org/ratatui) of the crate is reasonably
+good, but this can always be improved. Focus on keeping the tests simple and obvious and write unit
+tests for all new or modified code. Beside the usual doc and unit tests, one of the most valuable
+test you can write for Ratatui is a test against the `TestBackend`. It allows you to assert the
+content of the output buffer that would have been flushed to the terminal after a given draw call.
+See `widgets_block_renders` in [tests/widgets_block.rs](./tests/widget_block.rs) for an example.
+
+When writing tests, generally prefer to write unit tests and doc tests directly in the code file
+being tested rather than integration tests in the `tests/` folder.
+
+If an area that you're making a change in is not tested, write tests to characterize the existing
+behavior before changing it. This helps ensure that we don't introduce bugs to existing software
+using Ratatui (and helps make it easy to migrate apps still using `tui-rs`).
+
+For coverage, we have two [bacon](https://dystroy.org/bacon/) jobs (one for all tests, and one for
+unit tests, keyboard shortcuts `v` and `u` respectively) that run
+[cargo-llvm-cov](https://github.com/taiki-e/cargo-llvm-cov) to report the coverage. Several plugins
+exist to show coverage directly in your editor. E.g.:
+
+- <https://marketplace.visualstudio.com/items?itemName=ryanluker.vscode-coverage-gutters>
+- <https://github.com/alepez/vim-llvmcov>
+
+### Documentation
+
+Here are some guidelines for writing documentation in Ratatui.  
+Every public API **must** be documented.
+
+Keep in mind that Ratatui tends to attract beginner Rust users that may not be familiar with Rust
+concepts.
+
+#### Content
+
+The main doc comment should talk about the general features that the widget supports and introduce
+the concepts pointing to the various methods. Focus on interaction with various features and giving
+enough information that helps understand why you might want something.
+
+Examples should help users understand a particular usage, not test a feature. They should be as
+simple as possible.  
+Prefer hiding imports and using wildcards to keep things concise. Some imports may still be shown
+to demonstrate a particular non-obvious import (e.g. `Stylize` trait to use style methods).  
+Speaking of `Stylize`, you should use it over the more verbose style setters:
+
+```rust
+let style = Style::new().red().bold();
+// not
+let style = Style::default().fg(Color::Red).add_modifier(Modifiers::BOLD);
+```
+
+#### Format
+
+- First line is summary, second is blank, third onward is more detail  
+
+```rust
+/// Summary
+///
+/// A detailed description
+/// with examples.
+fn foo() {}
+```
+
+- Max line length is 100 characters  
+See [vscode rewrap extension](https://marketplace.visualstudio.com/items?itemName=stkb.rewrap)
+
+- Doc comments are above macros  
+i.e.
+
+```rust
+/// doc comment
+#[derive(Debug)]
+struct Foo {}
+```
+
+- Code items should be between backticks  
+i.e. ``[`Block`]``, **NOT** ``[Block]``
+
+### Deprecation notice
+
+We generally want to wait at least two versions before removing deprecated items so users have
+time to update. However, if a deprecation is blocking for us to implement a new feature we may
+*consider* removing it in a one version notice.
+
+### Use of unsafe for optimization purposes
+
+We don't currently use any unsafe code in Ratatui, and would like to keep it that way. However there
+may be specific cases that this becomes necessary in order to avoid slowness. Please see [this
+discussion](https://github.com/ratatui-org/ratatui/discussions/66) for more about the decision.
+
+## Continuous Integration
+
+We use Github Actions for the CI where we perform the following checks:
+
+- The code should compile on `stable` and the Minimum Supported Rust Version (MSRV).
+- The tests (docs, lib, tests and examples) should pass.
+- The code should conform to the default format enforced by `rustfmt`.
+- The code should not contain common style issues `clippy`.
+
+You can also check most of those things yourself locally using `cargo make ci` which will offer you
+a shorter feedback loop than pushing to github.
+
+## Relationship with `tui-rs`
+
+This project was forked from [`tui-rs`](https://github.com/fdehau/tui-rs/) in February 2023, with the
+[blessing of the original author](https://github.com/fdehau/tui-rs/issues/654), Florian Dehau
+([@fdehau](https://github.com/fdehau)).
+
+The original repository contains all the issues, PRs and discussion that were raised originally, and
+it is useful to refer to when contributing code, documentation, or issues with Ratatui.
+
+We imported all the PRs from the original repository and implemented many of the smaller ones and
+made notes on the leftovers. These are marked as draft PRs and labelled as [imported from
+tui](https://github.com/ratatui-org/ratatui/pulls?q=is%3Apr+is%3Aopen+label%3A%22imported+from+tui%22).
+We have documented the current state of those PRs, and anyone is welcome to pick them up and
+continue the work on them.
+
+We have not imported all issues opened on the previous repository. For that reason, anyone wanting
+to **work on or discuss** an issue will have to follow the following workflow:
+
+- Recreate the issue
+- Start by referencing the **original issue**: ```Referencing issue #[<issue number>](<original
+  issue link>)```
+- Then, paste the original issues **opening** text
+
+You can then resume the conversation by replying to this new issue you have created.

-`tui-rs` is a [Rust](https://www.rust-lang.org) library to build rich terminal
-user interfaces and dashboards. It is heavily inspired by the `Javascript`
-library [blessed-contrib](https://github.com/yaronn/blessed-contrib) and the
-`Go` library [termui](https://github.com/gizak/termui).
+<!-- cargo-rdme start -->

-The library itself supports four different backends to draw to the terminal. You
-can either choose from:

-The library is based on the principle of immediate rendering with intermediate
-buffers. This means that at each new frame you should build all widgets that are
-supposed to be part of the UI. While providing a great flexibility for rich and
-interactive UI, this may introduce overhead for highly dynamic content. So, the
-implementation try to minimize the number of ansi escapes sequences generated to
-draw the updated UI. In practice, given the speed of `Rust` the overhead rather
-comes from the terminal emulator than the library itself.

-### [Documentation](https://docs.rs/tui)
+# Ratatui

-### Demo
+[Ratatui][Ratatui Website] is a crate for cooking up terminal user interfaces in Rust. It is a
+lightweight library that provides a set of widgets and utilities to build complex Rust TUIs.
+Ratatui was forked from the [tui-rs] crate in 2023 in order to continue its development.

-The demo shown in the gif can be run with all available backends
-(`exmples/*_demo.rs` files). For example to see the `termion` version one could
-run:
+## Installation

-```
-cargo run --example termion_demo --release -- --tick-rate 200
+Add `ratatui` and `crossterm` as dependencies to your cargo.toml:
+
+```shell
+cargo add ratatui crossterm
 ```

-where `tick-rate` is the UI refresh rate in ms.
+Ratatui uses [Crossterm] by default as it works on most platforms. See the [Installation]
+section of the [Ratatui Website] for more details on how to use other backends ([Termion] /
+[Termwiz]).

-The UI code is in [examples/demo/ui.rs](examples/demo/ui.rs) while the
-application state is in [examples/demo/app.rs](examples/demo/app.rs).
+## Introduction

-Beware that the `termion_demo` only works on Unix platforms. If you are a Windows user,
-you can see the same demo using the `crossterm` backend with the following command:
+Ratatui is based on the principle of immediate rendering with intermediate buffers. This means
+that for each frame, your app must render all widgets that are supposed to be part of the UI.
+This is in contrast to the retained mode style of rendering where widgets are updated and then
+automatically redrawn on the next frame. See the [Rendering] section of the [Ratatui Website]
+for more info.

-```
-cargo run --example crossterm_demo --no-default-features --features="crossterm" --release -- --tick-rate 200
+You can also watch the [FOSDEM 2024 talk] about Ratatui which gives a brief introduction to
+terminal user interfaces and showcases the features of Ratatui, along with a hello world demo.

+## Other documentation
+
+- [Ratatui Website] - explains the library's concepts and provides step-by-step tutorials
+- [API Docs] - the full API documentation for the library on docs.rs.
+- [Examples] - a collection of examples that demonstrate how to use the library.
+- [Contributing] - Please read this if you are interested in contributing to the project.
+- [Changelog] - generated by [git-cliff] utilizing [Conventional Commits].
+- [Breaking Changes] - a list of breaking changes in the library.
+
+## Quickstart
+
+The following example demonstrates the minimal amount of code necessary to setup a terminal and
+render "Hello World!". The full code for this example which contains a little more detail is in
+the [Examples] directory. For more guidance on different ways to structure your application see
+the [Application Patterns] and [Hello World tutorial] sections in the [Ratatui Website] and the
+various [Examples]. There are also several starter templates available in the [templates]
+repository.
+
+Every application built with `ratatui` needs to implement the following steps:
+
+- Initialize the terminal
+- A main loop to:
+  - Handle input events
+  - Draw the UI
+- Restore the terminal state
+
+The library contains a [`prelude`] module that re-exports the most commonly used traits and
+types for convenience. Most examples in the documentation will use this instead of showing the
+full path of each type.
+
+### Initialize and restore the terminal
+
+The [`Terminal`] type is the main entry point for any Ratatui application. It is a light
+abstraction over a choice of [`Backend`] implementations that provides functionality to draw
+each frame, clear the screen, hide the cursor, etc. It is parametrized over any type that
+implements the [`Backend`] trait which has implementations for [Crossterm], [Termion] and
+[Termwiz].
+
+Most applications should enter the Alternate Screen when starting and leave it when exiting and
+also enable raw mode to disable line buffering and enable reading key events. See the [`backend`
+module] and the [Backends] section of the [Ratatui Website] for more info.
+
+### Drawing the UI
+
+The drawing logic is delegated to a closure that takes a [`Frame`] instance as argument. The
+[`Frame`] provides the size of the area to draw to and allows the app to render any [`Widget`]
+using the provided [`render_widget`] method. See the [Widgets] section of the [Ratatui Website]
+for more info.
+
+### Handling events
+
+Ratatui does not include any input handling. Instead event handling can be implemented by
+calling backend library methods directly. See the [Handling Events] section of the [Ratatui
+Website] for more info. For example, if you are using [Crossterm], you can use the
+[`crossterm::event`] module to handle events.
+
+### Example
+
+```rust
+use std::io::{self, stdout};
+
+use crossterm::{
+    event::{self, Event, KeyCode},
+    terminal::{disable_raw_mode, enable_raw_mode, EnterAlternateScreen, LeaveAlternateScreen},
+    ExecutableCommand,
+};
+use ratatui::{prelude::*, widgets::*};
+
+fn main() -> io::Result<()> {
+    enable_raw_mode()?;
+    stdout().execute(EnterAlternateScreen)?;
+    let mut terminal = Terminal::new(CrosstermBackend::new(stdout()))?;
+
+    let mut should_quit = false;
+    while !should_quit {
+        terminal.draw(ui)?;
+        should_quit = handle_events()?;
+    }
+
+    disable_raw_mode()?;
+    stdout().execute(LeaveAlternateScreen)?;
+    Ok(())
+}
+
+fn handle_events() -> io::Result<bool> {
+    if event::poll(std::time::Duration::from_millis(50))? {
+        if let Event::Key(key) = event::read()? {
+            if key.kind == event::KeyEventKind::Press && key.code == KeyCode::Char('q') {
+                return Ok(true);
+            }
+        }
+    }
+    Ok(false)
+}
+
+fn ui(frame: &mut Frame) {
+    frame.render_widget(
+        Paragraph::new("Hello World!")
+            .block(Block::default().title("Greeting").borders(Borders::ALL)),
+        frame.size(),
+    );
+}
 ```

-If the user interface contains glyphs that are not displayed correctly by your terminal, you may want to run
-the demo without those symbols:
+Running this example produces the following output:

-```
-cargo run --example crossterm_demo --no-default-features --features="crossterm" --release -- --tick-rate 200 --enhanced-graphics false
+![docsrs-hello]
+
+## Layout
+
+The library comes with a basic yet useful layout management object called [`Layout`] which
+allows you to split the available space into multiple areas and then render widgets in each
+area. This lets you describe a responsive terminal UI by nesting layouts. See the [Layout]
+section of the [Ratatui Website] for more info.
+
+```rust
+use ratatui::{prelude::*, widgets::*};
+
+fn ui(frame: &mut Frame) {
+    let main_layout = Layout::new(
+        Direction::Vertical,
+        [
+            Constraint::Length(1),
+            Constraint::Min(0),
+            Constraint::Length(1),
+        ],
+    )
+    .split(frame.size());
+    frame.render_widget(
+        Block::new().borders(Borders::TOP).title("Title Bar"),
+        main_layout[0],
+    );
+    frame.render_widget(
+        Block::new().borders(Borders::TOP).title("Status Bar"),
+        main_layout[2],
+    );
+
+    let inner_layout = Layout::new(
+        Direction::Horizontal,
+        [Constraint::Percentage(50), Constraint::Percentage(50)],
+    )
+    .split(main_layout[1]);
+    frame.render_widget(
+        Block::default().borders(Borders::ALL).title("Left"),
+        inner_layout[0],
+    );
+    frame.render_widget(
+        Block::default().borders(Borders::ALL).title("Right"),
+        inner_layout[1],
+    );
+}
 ```

-### Widgets
+Running this example produces the following output:

-The library comes with the following list of widgets:
+![docsrs-layout]

-  * [Block](examples/block.rs)
-  * [Gauge](examples/gauge.rs)
-  * [Sparkline](examples/sparkline.rs)
-  * [Chart](examples/chart.rs)
-  * [BarChart](examples/barchart.rs)
-  * [List](examples/list.rs)
-  * [Table](examples/table.rs)
-  * [Paragraph](examples/paragraph.rs)
-  * [Canvas (with line, point cloud, map)](examples/canvas.rs)
-  * [Tabs](examples/tabs.rs)
+## Text and styling

-Click on each item to see the source of the example. Run the examples with with 
-cargo (e.g. to run the demo `cargo run --example demo`), and quit by pressing `q`.
+The [`Text`], [`Line`] and [`Span`] types are the building blocks of the library and are used in
+many places. [`Text`] is a list of [`Line`]s and a [`Line`] is a list of [`Span`]s. A [`Span`]
+is a string with a specific style.

-You can run all examples by running `make run-examples`.
+The [`style` module] provides types that represent the various styling options. The most
+important one is [`Style`] which represents the foreground and background colors and the text
+attributes of a [`Span`]. The [`style` module] also provides a [`Stylize`] trait that allows
+short-hand syntax to apply a style to widgets and text. See the [Styling Text] section of the
+[Ratatui Website] for more info.

-### Third-party widgets
+```rust
+use ratatui::{prelude::*, widgets::*};

-* [tui-logger](https://github.com/gin66/tui-logger)
+fn ui(frame: &mut Frame) {
+    let areas = Layout::new(
+        Direction::Vertical,
+        [
+            Constraint::Length(1),
+            Constraint::Length(1),
+            Constraint::Length(1),
+            Constraint::Length(1),
+            Constraint::Min(0),
+        ],
+    )
+    .split(frame.size());

-### Apps using tui
+    let span1 = Span::raw("Hello ");
+    let span2 = Span::styled(
+        "World",
+        Style::new()
+            .fg(Color::Green)
+            .bg(Color::White)
+            .add_modifier(Modifier::BOLD),
+    );
+    let span3 = "!".red().on_light_yellow().italic();

+    let text: Text = Text::from(vec![line]);

-### Alternatives
+    frame.render_widget(Paragraph::new(text), areas[0]);
+    // or using the short-hand syntax and implicit conversions
+    frame.render_widget(
+        Paragraph::new("Hello World!".red().on_white().bold()),
+        areas[1],
+    );

-You might want to checkout [Cursive](https://github.com/gyscos/Cursive) for an
-alternative solution to build text user interfaces in Rust.
+    // to style the whole widget instead of just the text
+    frame.render_widget(
+        Paragraph::new("Hello World!").style(Style::new().red().on_white()),
+        areas[2],
+    );
+    // or using the short-hand syntax
+    frame.render_widget(Paragraph::new("Hello World!").blue().on_yellow(), areas[3]);
+}
+```

+## Status of this fork
+
+In response to the original maintainer [**Florian Dehau**](https://github.com/fdehau)'s issue
+regarding the [future of `tui-rs`](https://github.com/fdehau/tui-rs/issues/654), several members of
+the community forked the project and created this crate. We look forward to continuing the work
+started by Florian 🚀
+
+In order to organize ourselves, we currently use a [Discord server](https://discord.gg/pMCEU9hNEj),
+feel free to join and come chat! There is also a [Matrix](https://matrix.org/) bridge available at
+[#ratatui:matrix.org](https://matrix.to/#/#ratatui:matrix.org).
+
+While we do utilize Discord for coordinating, it's not essential for contributing.
+Our primary open-source workflow is centered around GitHub.
+For significant discussions, we rely on GitHub — please open an issue, a discussion or a PR.
+
+Please make sure you read the updated [contributing](./CONTRIBUTING.md) guidelines, especially if
+you are interested in working on a PR or issue opened in the previous repository.
+
+## Rust version requirements
+
+Since version 0.23.0, The Minimum Supported Rust Version (MSRV) of `ratatui` is 1.67.0.
+
+## Widgets
+
+### Built in
+
+The library comes with the following
+[widgets](https://docs.rs/ratatui/latest/ratatui/widgets/index.html):
+
+- [BarChart](https://docs.rs/ratatui/latest/ratatui/widgets/struct.BarChart.html)
+- [Block](https://docs.rs/ratatui/latest/ratatui/widgets/block/struct.Block.html)
+- [Calendar](https://docs.rs/ratatui/latest/ratatui/widgets/calendar/index.html)
+- [Canvas](https://docs.rs/ratatui/latest/ratatui/widgets/canvas/struct.Canvas.html) which allows
+  rendering [points, lines, shapes and a world
+  map](https://docs.rs/ratatui/latest/ratatui/widgets/canvas/index.html)
+- [Chart](https://docs.rs/ratatui/latest/ratatui/widgets/struct.Chart.html)
+- [Clear](https://docs.rs/ratatui/latest/ratatui/widgets/struct.Clear.html)
+- [Gauge](https://docs.rs/ratatui/latest/ratatui/widgets/struct.Gauge.html)
+- [List](https://docs.rs/ratatui/latest/ratatui/widgets/struct.List.html)
+- [Paragraph](https://docs.rs/ratatui/latest/ratatui/widgets/struct.Paragraph.html)
+- [Scrollbar](https://docs.rs/ratatui/latest/ratatui/widgets/scrollbar/struct.Scrollbar.html)
+- [Sparkline](https://docs.rs/ratatui/latest/ratatui/widgets/struct.Sparkline.html)
+- [Table](https://docs.rs/ratatui/latest/ratatui/widgets/struct.Table.html)
+- [Tabs](https://docs.rs/ratatui/latest/ratatui/widgets/struct.Tabs.html)
+
+Each widget has an associated example which can be found in the [Examples] folder. Run each example
+with cargo (e.g. to run the gauge example `cargo run --example gauge`), and quit by pressing `q`.
+
+You can also run all examples by running `cargo make run-examples` (requires `cargo-make` that can
+be installed with `cargo install cargo-make`).
+

+# Creating a Release
+
+[crates.io](https://crates.io/crates/ratatui) releases are automated via [GitHub
+actions](.github/workflows/cd.yml) and triggered by pushing a tag.
+
+1. Record a new demo gif if necessary. The preferred tool for this is
+[vhs](https://github.com/charmbracelet/vhs) (installation instructions in README).
+
+   ```shell
+   cargo build --example demo2
+   vhs examples/demo2.tape
+   ```
+
+1. Switch branches to the images branch and copy demo2.gif to examples/, commit, and push.
+1. Grab the permalink from <https://github.com/ratatui-org/ratatui/blob/images/examples/demo2.gif> and
+   append `?raw=true` to redirect to the actual image url. Then update the link in the main README.
+   Avoid adding the gif to the git repo as binary files tend to bloat repositories.
+
+1. Bump the version in [Cargo.toml](Cargo.toml).
+1. Ensure [CHANGELOG.md](CHANGELOG.md) is updated. [git-cliff](https://github.com/orhun/git-cliff)
+   can be used for generating the entries.
+1. Ensure that any breaking changes are documented in [BREAKING-CHANGES.md](./BREAKING-CHANGES.md)
+1. Commit and push the changes.
+1. Create a new tag: `git tag -a v[X.Y.Z]`
+1. Push the tag: `git push --tags`
+1. Wait for [Continuous Deployment](https://github.com/ratatui-org/ratatui/actions) workflow to
+   finish.
+
+## Alpha Releases
+
+Alpha releases are automatically released every Saturday via [cd.yml](./.github/workflows/cd.yml)
+and can be manually be created when necessary by triggering the [Continuous
+Deployment](https://github.com/ratatui-org/ratatui/actions/workflows/cd.yml) workflow.
+
+We automatically release an alpha release with a patch level bump + alpha.num weekly (and when we
+need to manually). E.g. the last release was 0.22.0, and the most recent alpha release is
+0.22.1-alpha.1.
+
+These releases will have whatever happened to be in main at the time of release, so they're useful
+for apps that need to get releases from crates.io, but may contain more bugs and be generally less
+tested than normal releases.
+
+See [#147](https://github.com/ratatui-org/ratatui/issues/147) and
+[#359](https://github.com/ratatui-org/ratatui/pull/359) for more info on the alpha release process.

+
+This folder contains unreleased code. View the [examples for the latest release
+(0.25.0)](https://github.com/ratatui-org/ratatui/tree/v0.25.0/examples) instead.
+
+> [!WARNING]
+>
+> There are backwards incompatible changes in these examples, as they are designed to compile
+> against the `main` branch.
+>
+> There are a few workaround for this problem:
+>
+> - View the examples as they were when the latest version was release by selecting the tag that
+>   matches that version. E.g. <https://github.com/ratatui-org/ratatui/tree/v0.25.0/examples>. There
+>   is a combo box at the top of this page which allows you to select any previous tagged version.
+> - To view the code locally, checkout the tag using `git switch --detach v0.25.0`.
+> - Use the latest [alpha version of Ratatui]. These are released weekly on Saturdays.
+> - Compile your code against the main branch either locally by adding e.g. `path = "../ratatui"` to
+>   the dependency, or remotely by adding `git = "https://github.com/ratatui-org/ratatui"`
+>
+> For a list of unreleased breaking changes, see [BREAKING-CHANGES.md].
+>
+> We don't keep the CHANGELOG updated with unreleased changes, check the git commit history or run
+> `git-cliff -u` against a cloned version of this repository.

+## How to update these examples
+
+These gifs were created using [VHS](https://github.com/charmbracelet/vhs). Each example has a
+corresponding `.tape` file that holds instructions for how to generate the images. Note that the
+images themselves are stored in a separate `images` git branch to avoid bloating the main
+repository.
+
+<!--
+
+Links to images to make them easier to update in bulk. Use the following script to update and upload
+the examples to the images branch. (Requires push access to the branch).
+
+```shell
+examples/vhs/generate.bash

+//! [tui-big-text] is a rust crate that renders large pixel text as a [Ratatui] widget using the
+//! glyphs from the [font8x8] crate.
+//!
+//! ![Hello World example](https://vhs.charm.sh/vhs-2UxNc2SJgiNqHoowbsXAMW.gif)
+//!
+//! # Installation
+//!
+//! ```shell
+//! cargo add ratatui tui-big-text
+//! ```
+//!
+//! # Usage
+//!
+//! Create a [`BigText`] widget using `BigTextBuilder` and pass it to [`Frame::render_widget`] to
+//! render be rendered. The builder allows you to customize the [`Style`] of the widget and the
+//! [`PixelSize`] of the glyphs. The [`PixelSize`] can be used to control how many character cells
+//! are used to represent a single pixel of the 8x8 font.
+//!
+//! # Example
+//!
+//! ```rust
+//! use anyhow::Result;
+//! use ratatui::prelude::*;
+//! use tui_big_text::{BigTextBuilder, PixelSize};
+//!
+//! fn render(frame: &mut Frame) -> Result<()> {

+//! How to use a panic hook to reset the terminal before printing the panic to
+//! the terminal.
+//!
+//! When exiting normally or when handling `Result::Err`, we can reset the
+//! terminal manually at the end of `main` just before we print the error.
+//!
+//! Because a panic interrupts the normal control flow, manually resetting the
+//! terminal at the end of `main` won't do us any good. Instead, we need to
