License

This linter verifies if a file has a known license header.

By default, Firefox uses MPL-2 license with the appropriate headers. In some cases (thirdpardy code), a file might have a different header file. If this is the case, one of the significant line of the header should be listed in the list {searchfox}of valid licenses <tools/lint/license/valid-licenses.txt>.

Run Locally

This mozlint linter can be run using mach:

.. parsed-literal::

    $ mach lint --linter license <file paths>

Configuration

This linter is enabled on most of the whole code base.

Autofix

This linter provides a --fix option that adds the right MPL-2 header at the right place depending on the script or source language.
