Rake

Rake is a Ruby make-like utility for defining and executing build tasks. It uses standard Ruby syntax for Rakefiles, avoiding traditional Makefile complexities.

Description

Rake is a simple Ruby build program with capabilities similar to make. Rakefiles, Rake's version of Makefiles, are completely defined in standard Ruby syntax, eliminating the need for XML files or quirky Makefile syntax concerns like tabs versus spaces.

Users can specify tasks with prerequisites, and Rake supports rule patterns to synthesize implicit tasks. It is lightweight and can be distributed with other projects as a single file, meaning projects depending on Rake do not require it to be installed on target systems.

This makes Rake suitable for Ruby-based build automation and task management in development environments.

How It Works

Rake operates by parsing Rakefiles written in standard Ruby syntax to define tasks and their prerequisites. It resolves dependencies, supports rule patterns for implicit task synthesis, and executes tasks in a make-like manner, tracing rules and managing job statistics as needed.

Installation

bash
sudo apt install rake

Flags

--backtrace=[OUT]Enable full backtrace. OUT can be stderr (default) or stdout.
--commentsShow commented tasks only
--job-stats [LEVEL]Display job statistics. LEVEL=history displays a complete job list
--rulesTrace the rules resolution.
--suppress-backtrace PATTERNSuppress backtrace lines matching regexp PATTERN. Ignored if --trace is on.
-A, --allShow all tasks, even uncommented ones (in combination with -T or -D)
-B, --build-allBuild all prerequisites, including those which are up-to-date.
-C, --directory [DIRECTORY]Change to DIRECTORY before doing anything.
