Mactag with FSSM

When I first released Mactag I got a question about automatic updating of TAGS-files when changing file contents. Today Mactag can do this, with a little bit of help.

First, you need Mactag version 0.4.0 and the fssm Rubygem. The new version of Mactag includes a rake task called mactag:server. Calling this will start a server that listens for file changes in the project.

With the server started, changes to project files, creation of new files and removal of files will trigger Mactag to update, create or remove the corresponding TAGS-file.

Your editor however needs to be aware of TAGS-files changes. I created an Emacs script called Mactag.el that makes sure find-tag have the correct TAGS-tables before lookup.
