PyRegexPlayground

Python re(gex)? playground

This TUI application is intended as an interactive playground for Python Regular Expressions. The app also includes a comprehensive cheatsheet and several interactive examples.

Installation

This app is available on PyPI as regexplayground. Example installation instructions are shown below, adjust them based on your preferences and OS.

# virtual environment
$ python3 -m venv textual_apps
$ cd textual_apps
$ source bin/activate
$ pip install regexplayground

# launch the app
$ regexplayground

To run the app without having to enter the virtual environment again, add this alias to .bashrc (or equivalent):

# you'll have to change the path
alias regexplayground='/path/to/textual_apps/bin/regexplayground'

As an alternative to manually managing such virtual environments, you can use https://github.com/pypa/pipx instead:

$ pipx install regexplayground
$ regexplayground

As yet another alternative, you can install textual==0.85.2 (see Textual documentation for more details), clone this repository and run the pyregex_playground.py file.

Adjust the terminal dimensions for the widgets to appear properly, for example 84x25 (characters x lines). Here are some sample screenshots:
