Mode line — Firefox Source Docs documentation (original) (raw)

Files should have Emacs and vim mode line comments as the first two lines of the file, which should set indent-tabs-mode to nil. For new files, use the following, specifying two-space indentation:

/* -- Mode: C++; tab-width: 2; indent-tabs-mode: nil; c-basic-offset: 2 -- / / vim: set ts=2 et sw=2 tw=80: / / This Source Code Form is subject to the terms of the Mozilla Public

Be sure to use the correct Mode in the first line, don’t use C++ in JavaScript files.
