How to get path to the current vimscript being executed

Question

In my vim plugin, I have two files:

myplugin/plugin.vim myplugin/plugin_helpers.py 

I would like to import plugin_helpers from plugin.vim (using the vim python support), so I believe I first need to put the directory of my plugin on python's sys.path.

How can I (in vimscript) get the path to the currently executing script? In python, this is __file__. In ruby, it's __FILE__. I couldn't find anything similar for vim by googling, can it be done?

Note: I am not looking for the currently edited file ("%:p" and friends).

Answer 1

" Relative path of script file: let s:path = expand('<sfile>')  " Absolute path of script file: let s:path = expand('<sfile>:p')  " Absolute path of script file with symbolic links resolved: let s:path = resolve(expand('<sfile>:p'))  " Folder in which script resides: (not safe for symlinks) let s:path = expand('<sfile>:p:h')  " If you're using a symlink to your script, but your resources are in " the same directory as the actual script, you'll need to do this: "   1: Get the absolute path of the script "   2: Resolve all symbolic links "   3: Get the folder of the resolved absolute file let s:path = fnamemodify(resolve(expand('<sfile>:p')), ':h') 

I use that last one often because my ~/.vimrc is a symbolic link to a script in a git repository.
