Without a terminal-resetting panic hook there are two main problems when
an application panics:
1. The report of the panic is distorted because the terminal has not
properly left the alternate screen and is still in raw mode.
2. The terminal needs to be manually reset with the `reset` command.
To avoid this, the standard panic hook can be extended to first reset
the terminal.
Third column in table example was using the `Max` constraint.
But since version 0.16, the layout system does not add a hidden constraint on the last column which would ensure that it fills the remaining available space (a change that was already mentioned in #525). In addition, `tui` does not support sizing based on content because of its immediate mode nature. Therefore, `Max` is now resolved to `0`. Replacing with `Min` fixes the issue.
A new way of specifying constraints is being worked on at #519 which should for more deterministic and advanced layout.
The thread spawned by `Events` to listen for keyboard inputs had knowlegde of
the exit key to exit on its own when it was pressed. It is however a source of
confusion (#491) because the exit behavior is wired in both the event handler
and the input handling performed by the app. In addition, this is not needed as
the thread will exit anyway when the main thread finishes as it is already the
case for the "tick" thread. Therefore, this commit removes both the option to
configure the exit key in the `Events` handler and the option to temporarily
ignore it.
* Added ability to set title alignment, added tests, modified blocks example to show the feature
* Added test for inner with title in block
* Updated block example to show center alignment
* Formatting fixed
* Updated tests to use lamdas and be more concise. Updated title alignmnet code to be more straightforward and have correct behavior when placing title in the center without left border
- control over the style of each cell and its content using the styling capabilities of Text.
- rows with multiple lines.
- fix panics on small areas.
- less generic type parameters.
* gauge now uses unicode blocks for more descriptive progress
* removed unnecessary if
* changed function name to better reflect unicode
* standardized block symbols, added no unicode option, added tests
* formatting
* improved readability
* gauge tests now check color
* formatted
- merge `Style` and `StyleDiff` together. `Style` now is used to activate or deactivate certain
style rules not to overidden all of them.
- update all impacted widgets, examples and tests.
* `Paragraph:scroll` takes a tuple of offsets instead of a single vertical offset.
* `LineTruncator` takes this new horizontal offset into account to let the paragraph scroll horizontally.
- Remove deny warnings in lib.rs. This allows easier iteration when developing
new features. The warnings will make the CI fails anyway on the clippy CI
stage.
- Run clippy on all targets (including tests and examples) and all features.
- Fail CI on clippy warnings.
* Update the `Shape` trait. Instead of returning an iterator of point, all
shapes are now aware of the surface they will be drawn to through a `Painter`.
In order to draw themselves, they paint points of the "braille grid".
* Rewrite how lines are drawn using a common line drawing algorithm (Bresenham).
Most widgets can be drawn directly based on the input parameters. However, some
features may require some kind of associated state to be implemented.
For example, the `List` widget can highlight the item currently selected. This
can be translated in an offset, which is the number of elements to skip in
order to have the selected item within the viewport currently allocated to this
widget. The widget can therefore only provide the following behavior: whenever
the selected item is out of the viewport scroll to a predefined position (make
the selected item the last viewable item or the one in the middle).
Nonetheless, if the widget has access to the last computed offset then it can
implement a natural scrolling experience where the last offset is reused until
the selected item is out of the viewport.
To allow such behavior within the widgets, this commit introduces the following
changes:
- Add a `StatefulWidget` trait with an associated `State` type. Widgets that
can take advantage of having a "memory" between two draw calls needs to
implement this trait.
- Add a `render_stateful_widget` method on `Frame` where the associated
state is given as a parameter.
The chosen approach is thus to let the developers manage their widgets' states
themselves as they are already responsible for the lifecycle of the wigets
(given that the crate exposes an immediate mode api).
The following changes were also introduced:
- `Widget::render` has been deleted. Developers should use `Frame::render_widget`
instead.
- `Widget::background` has been deleted. Developers should use `Buffer::set_background`
instead.
- `SelectableList` has been deleted. Developers can directly use `List` where
`SelectableList` features have been back-ported.
* removed flush calls because execute already calls flush under the hood.
* moved some static functions into From traits
* removed useless clone in demo
* upgrade to crossterm 0.13
* map all errors
This allows table column widths to be adapted more and scale with the
UI.
The constraints are solved using the Cassowary solver. An added
constraint for fitting them all in the width is added.
* Remove compilation warnings
* Fix rendering artifacts in the crossterm demo. In particular, the bold modifier
was leaking on most of the terminal screen because the old logic was not
properly unsetting the bold modifier after use (took inspiration of the termion
backend implementation)
