Exit early if required binaries aren't found on PATH Developers who haven't set up their environment properly often see hard-to-decipher errors when running recipes.py. This should make the error easier to understand.

Recipes are a domain-specific language (embedded in python) for specifying sequences of subprocess calls in a cross-platform and testable way.
README.md
This file!
doc/
Documentation for the recipe engine (including this file!). See the design doc for more detailed design information about the recipe engine.
infra/
Chrome infra config files.
recipes.py
The main entry point to the recipe engine. It has many subcommands and flags; run recipes.py -h
to see them. Include this in your repository to start using recipes.
recipes/
Recipes in the recipe engine. These are either example recipes, or recipes which are used to test the engine (see run_test.py to see these run)
recipe_modules/
Built in recipe modules. These are very useful when writing recipes; take a look in there, and look at each of their examples
subfolders to get an idea how to use them in a recipe.
recipe_engine/
The core functionality of the recipe engine. Noteworthy files include:
main.py
-- The main entrypoint for the recipe engine.recipes_cfg.proto
-- The protobuf file which defines the format of a recipes.cfg
file.third_party/
-- third_party code which is vendored into the recipe engine.recipe_api.py
-- The api exposed to a recipe module.unittests
-- Unittests for the engine.There are also several files which correspond to a subcommand of recipes.py; run
, and autoroll
are some examples.
unittests/
Somewhat poorly named, these are higher level integration tests.
user.email
and user.name
are configured in git config
