Fnug is a command runner, well actually it's a terminal multiplexer (like tmux), but with a focus on running all your lint and test commands, at once, and displaying the result of those command. Confused? Watch the demo

• User-friendly terminal interface, with 100% support for both keyboard and mouse navigation
• Git integration, automatically select lints and tests that's should be run, based on what files have uncommitted changes
• Track file changes, and selects commands based on the changed files
• Terminal emulation with scroll back, for those really long error messages

Python 3.10 or later is required.

pipx or rye tool are highly recommended:

# Recommended
pipx install fnug
# (or with rye tool)
rye install fnug
# Via pip (NOT RECOMMENDED)
pip install fnug

To start fnug you only need to run it in a directory with a .fnug.yaml configuration file (or with the argument -c path/to/config.yaml)

Fnug is controlled by a .fnug.yaml configuration file (or .fnug.json if thats more your speed).

Runs a single commands

fnug_version: 0.1.0
name: fnug
commands:
  - name: hello
    cmd: echo world

Uses git auto to select commands based on what files have uncommitted changes (reselect by pressing "g")

fnug_version: 0.1.0
name: fnug
commands:
  - name: hello
    cmd: echo world
    auto:
      git: true
      path:
        - "./"
      regex:
        - "\\.fnug\\.yaml$"

Uses file watching to monitor the file system for changes, and select commands accordingly, can be combined with git auto

fnug_version: 0.1.0
name: fnug
commands:
  - name: hello
    cmd: echo world
    auto:
      watch: true
      path:
        - "./"
      regex:
        - "\\.fnug\\.yaml$"

View this projects .fnug.yaml file for an advanced example
