Getting started

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.

Your platform

Linux (all distros)

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

macOS

The default terminal app is limited to 256 colors. We recommend installing a newer terminal such as iterm2, Kitty, or WezTerm.

Windows

The new Windows Terminal runs Textual apps beautifully.

Installation

Here's how to install Textual.

From PyPI

You can install Textual via PyPI, with the following command:

pip install textual

If you plan on developing Textual apps, you should also install textual developer tools:

pip install textual-dev

From conda-forge

Textual is also available on conda-forge. The preferred package manager for conda-forge is currently micromamba:

micromamba install -c conda-forge textual

And for the textual developer tools:

micromamba install -c conda-forge textual-dev

Textual CLI

If you installed the developer tools you should have access to the textual command. There are a number of sub-commands available which will aid you in building Textual apps. Run the following for a list of the available commands:

textual --help

See devtools for more about the textual command.

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:

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

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

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 ../
