Arcanist is a wrapper script that sits on top of other tools (e.g., Differential, linters, unit test frameworks, Git, Mercurial, and SVN) and provides pretty good command-line access to manage code review and perform some related revision control operations. Browse or close tasks, Flag an object, build a Paste, or waste time with arc anoid.

Primarily, Arcanist is helpful to manage code review with Differential and related source control operations. Examples include:

• arc diff sends your code for review, testing lint and unit first.
• arc patch applies another revision to the working copy
• arc land push changes to Git and Mercurial servers

After you configure unit and lint tests, you can analyze your changes with these commands:

• check your code for syntax and style errors with arc lint
• run unit tests that cover your changes with arc unit
• arc land to send your accepted revision up to the repository
• arc help will show you all available commands
