bakery 🧁

Bakery is an (opinionated) automation tool designed to simplify repetitive, time-consuming and error prone commands. It uses YAML instead of a propriatery language and provides handy defaults, such as help and version. Its main goal is to make the developer experience more familiar, flexible and friendly while being fast and reliable.

Installation

Bakery can be installed with the following methods:

• Go

Go

Use the go CLI tool to install Bakery:

go install github.com/kampanosg/bakery/cmd/bake@latest

Usage

CLI

To run a Bakefile and its available recipes, use the bake CLI tool. For example:

bake version
bake build

Flags

The CLI ships with a set of command line flags that can be used to extract information from the tool or modify its behaviour.

flag	description	default
-version	prints the current version of the tool
-verbose	controls the verbosity. if set to true the tool prints a lot more to stdout	false
-help	prints a help message with all the available flags

To use the flags, you can pass them directly to the CLI:

bake -version
bake -verbose build
bake -help

ℹ️ The -verbose flag can be used with recipes

The Bakefile

Bakery, by default, looks for a Bakefile from the directory that is executed. The Bakefile, should follow the YAML structure and contain the keywords and syntax described bellow.

The --file flag can be passed to use a Bakefile in a different location. For example, bake --file /path/to/Bakefile version
