If you use Sublime Text, now you can generate a trac.webkit.org hyperlink to a selected code line using the Copy WebKit Permalink plugin (as of <https://trac.webkit.org/changeset/235981/>). See <https://trac.webkit.org/browser/webkit/trunk/Tools/CopyPermalink/Sublime%20Text/INSTALL> for more details.

I tested the plugin on Mac with Sublime Text 3. The plugin should work on Windows and Linux. Fixes and improvements are welcome :) Happy hacking.
