Overview

rich.tui

Rich.tui is a TUI (Text User Interface) framework for Python using Rich as a renderer.

The end goal is to be able to rapidly create rich terminal applications that look as good as possible (within the restrictions imposed by a terminal emulator).

Rich TUI will integrate tightly with its parent project, Rich. Any of the existing renderables can be used in a more dynamic application.

This project is currently a work in progress and may not be usable for a while. Follow @willmcgugan for progress updates, or post in Discussions if you have any requests / suggestions.

As of 0.6.0, bindings on (at least) `left`, `right`, `up` and `down` no longer appear to work

With Textual 0.5.0 I had bindings on the arrow keys that worked fine. Having upgraded to 0.6.0 those bindings no longer seem to work. Isolating the issue I can recreate with this code (some other keys thrown in as control tests)

from textual.app import App, ComposeResult
from textual.widgets import TextLog, Header, Footer
from textual.binding import Binding
from textual.events import Key

class Binder( App[ None ] ):

    CSS = """
    TextLog {
        background: #222200;
        color: #BBBB00;
        text-style: bold;
    }
    """

    BINDINGS = [
        Binding( "up",    "log( 'up' )", "Up" ),
        Binding( "down",  "log( 'down' )", "Down" ),
        Binding( "left",  "log( 'left' )", "Left" ),
        Binding( "right", "log( 'right' )", "Right" ),
        Binding( "a", "log( 'a' )", "a" ),
        Binding( "s", "log( 's' )", "s" ),
        Binding( "d", "log( 'd' )", "d" ),
        Binding( "f", "log( 'f' )", "f" ),
        Binding( "left_square_bracket", "log( '[' )", "[" ),
        Binding( "right_square_bracket", "log( ']' )", "]" ),
    ]

    def compose( self ) -> ComposeResult:
        yield Header()
        yield TextLog()
        yield Footer()

    def on_mount( self ) -> None:
        self.query_one( TextLog ).write( "Ready..." )
        self.query_one( TextLog ).write( "Key bindings being looked for:" )
        self.query_one( TextLog ).write( ", ".join(
            [ binding.key for binding in self.BINDINGS ]
        ) )

    def action_log( self, name: str ) -> None:
        self.query_one( TextLog ).write( f"Via binding: {name}" )

    def on_key( self, event: Key ) -> None:
        self.query_one( TextLog ).write( f"Via event: {event!r}" )

if __name__ == "__main__":
    Binder().run()

Running the above, pressing the arrow keys vs some of the other keys...

Method to run code in a thread
I'd like to add a convenient method to execute in job in a thread.

It would probably be added to message pump (used by app / widgets).

It should allow a method to be called with arbitrary parameters, and should return an awaitable.

await self.call_threaded(my_code, "foo", "bar")

I can see this being used for jobs such as reading from disk (which at the moment blocks the vent loop).

Some considerations: a thread pool may be appropriate. We don't want this to be unbounded and potentially launch an unlimited number of threads. It should probably work with both async and sync functions, which will require a little inspection. If you want to tackle this, please discuss your ideas here first.

Add more easing functions
There are a number of 'easing functions' used by the animation system. At the top of _animator.py you will see the following:

EASING = { "none": lambda x: 1.0, "round": lambda x: 0.0 if x < 0.5 else 1.0, "linear": lambda x: x, "in_cubic": lambda x: x * x * x, "in_out_cubic": lambda x: 4 * x * x * x if x < 0.5 else 1 - pow(-2 * x + 2, 3) / 2, "out_cubic": lambda x: 1 - pow(1 - x, 3), }

These function have been copied from https://easings.net/ and translated from Javascript to Python. I would like to add the remaining functions to the EASING dict above.

See the animation.py example as a way of testing the above functions.

feat: initial datatable reactive values

For #1164, adds the six reactive attributes listed in the docs for DataTable to __init__. I noticed the class has three more reactive attributes (cursor_type, cursor_cell, and hover_cell) that aren't listed, but I left those out. Let me know if any of them should also be included.

Unclosed event loop with easing example
Every time I close the easing example. I get the following error:

/usr/lib/python3.9/asyncio/base_events.py:681: ResourceWarning: unclosed event loop <_UnixSelectorEventLoop running=False closed=False debug=False> _warn(f"unclosed event loop {self!r}", ResourceWarning, source=self) ResourceWarning: Enable tracemalloc to get the object allocation traceback

I am thinking there are still messages processing at shutdown that are keeping the loop running, but I have not been able to track down the root cause yet.

Possibly a similar issue to #82?

Live console widget

It would be nice to have a widget that behaves like a console. At first, just able to print and auto-scroll, and scroll bar, with auto-refresh. console.print("another brick in the wall")

Maybe reuse Rich's Live View / Console?

Wrong CSS styles being applied on hover
I noticed this when adding semantic style variants for Button.

When I hover over the warning button, the border is being set to tall $primary-lighten-3. I would expect it to be set to tall $warning-lighten-3 given Button.-warning has higher specificity.

Relevant CSS

Button { border: tall $primary-lighten-3; } Button.-warning { background: $warning; color: $text-warning; border: tall $warning-lighten-3; } Button.-warning :hover { background: $warning-darken-1; color: $text-warning-darken-1; }

Tabbed Widget
What?

This PR adds a widget that enables the user to define multiple views as so called tabs and receive a automagically generated bar of tab handles to switch between said views.

🖼 Some Pictures

The example code introduced in this PR produces the following:

Some additional info

All 4 modes a tab handle can be in are "user-stylable". Those being default, hover, selected, and hover+selected.

The type of view a tab uses can be given by the user upon tab creation. Though this is not strictly necessary thanks to DockView.dock_grid().

Mouse click and scroll event support for git-bash/mintty on Windows

The demo looks correct in git-bash on Windows, however it does not respond to mouse movement, click, and scroll events. It would be helpful to extend the existing drivers or driver selection to take this scenario into account. While the platform check will show "Windows", git-bash supports the event types in the Linux driver instead.

0;70;13M #left mouse button down 0;70;13m #left mouse button up

It's possible that a more nuanced environment check and loading the Linux driver in that case may enable it to work as expected.

add a "thin" horiz scrollbar

First, a screenshot:

I don't like the horizontal scrollbar; even at "size" 1 it is still too fat. So I added an option for a "thin" version, refactoring ScrollBarRender along the way.

I didn't presume to know how you'd like the CSS to behave, so I went for the simplest I could think of: add a new "scrollbar-thin" boolean style. I am not married to the css design around it, I really only want the "thin" version.

There's no need to do anything special for a "thin" vertical scrollbar: imo it looks very nice at width 1.

basic typing fixes

Hello there. I've run in a small number of typing issues in Textual during my everyday use, and thought I'd attempt a fix in Textual itself.

My ambitious goal is to run mypy --strict on all the codebase with zero warnings, and I'm about 50% of the way though. However that would be a non-small PR, so I thought I'd start with some obvious issues that should be easy to accept hopefully.

I've included here a fairly small number of changes, all of which I consider "obvious fixes" in the sense that they either expose actual bugs that exist now, or they break Python contracts, which are bugs waiting to happen.

I am going to annotate this PR with my reasoning below in a few minutes.

I hope this is useful. Cheers.

Also in this release, we've made fr units more useful. These CSS units can be used to easily create flexible layouts. See the video below:

https://user-images.githubusercontent.com/554369/199053126-e16c7047-11ae-4f97-95e7-ca264247184a.mov
