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

Overview

Textual

Textual 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)

        BINDINGS = [

            yield Footer()
    
        def on_mount( self ) -> None:
            self.query_one( TextLog ).write( "Ready..." )
            self.query_one( TextLog ).write( "Key bindings being looked for:" )

    if __name__ == "__main__":

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

  • Method to run code in a thread

    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

    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.

    Wrong CSS styles being applied on hover

    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.

  • Tabbed Widget

    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: Screenshot 2021-08-11 at 19 09 04 Screenshot 2021-08-11 at 19 09 08 Screenshot 2021-08-11 at 19 09 11

    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().

    Make default filename for screenshots use ISO8601 datetime format

    Currently, the save_screenshot function uses a datetime format by default that (a) introduces spaces to the resulting filename and (b) does not match what is specified in the doc-string. This PR will replace those spaces and bring the datetime format closer to the ISO8601 format. (Since colons are a reserved character, the format will not exactly match ISO8601.)

  • Call from thread method

    Call from thread method

    This is a step towards having an answer to devs who want to integrate a third-party API with Textual.

    The call_from_thread takes a callback that will be called in the app's loop from a thread. It will block until the callback returns. If integrating with a threaded API (many are under the hood), this will generally give the most predictable behaviour.

    There are downsides: you call it from the same thread as the app. Otherwise it would deadlock.

    I'll leave this method undocumented for now. We will at least have an answer for the next version, and we can work on greater syntactical sugar in the meantime.

  • Text Log widget cannot select app.console

    Text Log widget cannot select app.console

    I have Text Log widget implemented in a multithreaded app that is receiving callbacks from another python (Lightstreamer) class. More often than not when using the write method of the TextLog class when it tries to map to self.app.console (line 94):

    console = self.app.console

    the debugger throws an error saying it cannot find the app.

    I worked around this by making the assignment during the class initialization. It seems to work fine then. It seems like it loses the app context somehow.

  • Fix

    Fix "tree scrolls back to left"

    this is a proposal for fixing #1453. This passes tests for my locally.

    along the way:

    make Tree._refresh_node somewhat more efficient by: * stopping early * coallescing multiple refresh() calls of single lines into one call

    change "TreeControl" to "Tree" in a few texts (and funny enough, in demo.css, which doesn't even use it);

    remove the (appearantly dead) Tree._refresh_node_line

  • v0.3.0(Oct 31, 2022)
