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:
-
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.
-
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/* plugin/
