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);
```
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 of `vec![]` can no longer be
inferred.
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 a `Vec<_>`.
This allows to build list like
```
List::new(["Item 1", "Item 2"])
```
BREAKING CHANGE: `List::new` parameter type changed from `Into<Vec<ListItem<'a>>>`
to `IntoIterator<Item = Into<ListItem<'a>>>`
This prevents creating a table that doesn't actually render anything.
Fixes: https://github.com/ratatui-org/ratatui/issues/537
BREAKING CHANGE: Table::new() now takes an additional widths parameter.
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.
BREAKING CHANGE: The `Tab` widget now renders the highlight style as
reversed text by default. This can be changed by setting the
`highlight_style` field of the `Tab` widget.
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);
```
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`.
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
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()]));
```

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.

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

* 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

* 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

- 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

* 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.
