Remove underscore pauses from (hopefully) all snapshots
This seeks to remove the "_" from the key presses of snapshots and inline
runs in the documentation. The "_" no longer does anything, but got legacy
reasons at the moment we can't actually allow "_" to be an input to a
"faked" keypress in the docs and snapshots.

Removing these clears the way to letting "_" have the same status as any
other character.

All you need to get started building Textual apps.

Requirements

Textual requires Python 3.7 or later (if you have a choice, pick the most recent Python). Textual runs on Linux, macOS, Windows and probably any OS where Python also runs.

!!! info inline end "Your platform"

### :fontawesome-brands-linux: Linux (all distros)

All Linux distros come with a terminal emulator that can run Textual apps.

### :material-apple: macOS

The default terminal app is limited to 256 colors. We recommend installing a newer terminal such as [iterm2](https://iterm2.com/), [Kitty](https://sw.kovidgoyal.net/kitty/), or [WezTerm](https://wezfurlong.org/wezterm/).

### :material-microsoft-windows: Windows

The new [Windows Terminal](https://apps.microsoft.com/store/detail/windows-terminal/9N0DX20HK701?hl=en-gb&gl=GB) runs Textual apps beautifully.

Installation

You can install Textual via PyPI.

If you plan on developing Textual apps, then you should install textual[dev]. The [dev] part installs a few extra dependencies for development.

pip install "textual[dev]"

If you only plan on running Textual apps, then you can drop the [dev] part:

pip install textual

Demo

Once you have Textual installed, run the following to get an impression of what it can do:

python -m textual

If Textual is installed you should see the following:

Examples

The Textual repository comes with a number of example apps. To try out the examples, first clone the Textual repository:

=== "HTTPS"

```bash
git clone https://github.com/Textualize/textual.git
```

=== "SSH"

```bash
git clone git@github.com:Textualize/textual.git
```

=== "GitHub CLI"

```bash
gh repo clone Textualize/textual
```

With the repository cloned, navigate to the /examples/ directory where you will find a number of Python files you can run from the command line:

cd textual/examples/
python code_browser.py ../

Textual CLI

If you installed the dev dependencies you have access to the textual CLI command. There are a number of sub-commands which will aid you in building Textual apps.

textual --help

See devtools for more about the textual command.
