It also warns if you're +trying to change a string without changing the ID, or to add a string that's +still in use in a stable channel with a different value. + +The warnings on string ID changes get reported on phabricator, but they're +not making the build fail. To find out when to change IDs and when not to, +read the :ref:`Lifecycle & Workflow <Localization>` section in the +localization documentation. + +Run Locally +----------- + +The can be run using mach: + +.. parsed-literal:: + + $ mach lint --linter l10n <file paths> + +Alternatively, omit the ``--linter l10n`` and run all configured linters, which +will include the l10n linter. + + +Updating the Reference +---------------------- + +The linter checks out the cross-channel localization files into your +``.mozbuild`` state directory.
