If you use ctags to make tags files of your source, it's nice to be able to re-run ctags on a source file when you save it.

However, using ctags -a will only change existing entries in a tags file or add new ones. It doesn't delete entries that no longer exist. Should you delete an entity from your source file that's represented by an entry in a tags file, that entry will remain after calling ctags -a.

This python function will do two things:

1. It will search for a tags file starting in the directory where your source file resides and moving up a directory at a time until it either finds one or runs out of directories to try.

2. Should it find a tags file, it will then delete all entries in said tags file referencing the source file you've just saved and then execute ctags -a on that source file using the relative path to the source file from the tags file.

This way, every time you save a file, your tags file will be seamlessly updated.

Currently I suggest you simply cd git clone git://github.com/craigemery/vim-autotag.git cd ~/.vim/ mkdir -p plugin cp ~/vim-autotag.git/plugin/autotag.vim plugin/
