What's in the oven?

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 inherited 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.

Automate Workflows — Bootstrap Development Environments — Commit The Tasks

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 arbitrary scripting languages (e.g. Python).

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

Installing `$ bake`

**Various `*`nix Distributions** (Python 3.6+):

The primary installation method of bake, today, is via pip:

$ pip3 install bake-cli
Collecting bake-cli
…
Successfully installed bake-cli-0.2.0 delegator.py-0.1.1 pexpect-4.7.0 ptyprocess-0.6.0

This will always work, but it will not be the default recommendation.

MacOS (Previously known as OS X)

Installation of bake will (soon) be very easy, with Homebrew. The formula needs a subtle adjustment — if you want to help, here's the repo!

$ brew install kennethreitz/-/bake
==> Installing bake from kennethreitz/-
…
🍺  /usr/local/Cellar/bake/19-09-16: 1,563 files, 16.7MB, built in 11 seconds

Homebrew will be the primary installation target of bake.

Containers! e.g. Docker.

You an also run bake via Docker! An official image has been made available:

$ docker run kennethreitz/bake                                                                                                                                                                       Wed Sep 18 10:11:01 2019

Skip Steps, Automatically

Because we configured yarn.lock and Pipfile.lock as cache keys, bake will automatically skip the configured steps— only running them when the files are changed!

So, let's run that command again :)

$ bake install
 + Skipping install/node:
 + Skipping install/python.
 + Executing install:
 + Done.

Neat, eh?

Passing Values (Arguments & Parameters)

$ bake utils/argv KEY=VALUE 1 2 3
 + Executing utils/argv:
 |  WORLD: 1 2 3
 + Done.

Added Peace of Mind

$ bake utils/deploy
   What is 10 times 2?: 7
