It's easy to see how the complexity of running all of these +different kinds of linters in all of these different places could quickly balloon out of control. + +``Mozlint`` is a library that accomplishes several goals: + +1. It provides a standard method for adding new linters to the tree, which can be as easy as + defining a config object in a ``.yml`` file. This helps keep lint related code localized, and + prevents different teams from coming up with their own unique lint implementations. +2. It provides a streamlined interface for running all linters at once. Instead of running N + different lint commands to test your patch, a single ``mach lint`` command will automatically run + all applicable linters. This means there is a single API surface that other tools can use to + invoke linters. +3. With a simple taskcluster configuration, Mozlint provides an easy way to execute all these jobs + at review phase. + +``Mozlint`` isn't designed to be used directly by end users. Instead, it can be consumed by things +like mach, phabricator and taskcluster. |
