☿ bake— the strangely familiar task runner.

I love using Makefile for one-off tasks in projects.

The problem with doing this is that you can't use familiar bash–isms when doing so, as GNU Make doesn't use the familiar Bash syntax, nor does it allow for simple ad–hoc use of abritrary scripting languages (e.g. Python).

This project seeks to bridge all of these worlds into a single entrypoint — ideal for cross–language repositories.

$ bake -h
Usage: bake [OPTIONS] [TASK] [ARGUMENTS]...

  bake — the strangely familiar task–runner.

Options:
  -b, --bakefile PATH      The Bakefile to use.
  -l, --list               Lists available tasks.
  --allow TEXT             Whitelist an environment variable for use.
  --yes                    Set medium–security prompts to yes.
  -c, --continue           Continue, if a task fails.
  --insecure               Inherit parent shell's environment variables.
  -s, --silent             Reduce output.
  -e, --environ-json TEXT  Provide environment variables via JSON.
  -j, --json               Output in JSON format (stdout).
  -h, --help               Show this message and exit.

Features 'n Things

• A Bakefile, which looks and feels like the good parts of a Makefile.
• Except, you can write real bash code!
• Environment variables are explicitly passed or whitelisted (allowed), not inherinted from the parent shell.
• Unlike Makefile, either tabs or 4 spaces can be used.
• Tasks can be run safely and reliably. Rest assured that scripts are executed from the project root (e.g. location of the Bakefile).
• See advanced example for further, juicy, details.
