I install gvimPortable in a thumb drive.
The $VIMRUNTIME is d:\Dropbox\Portable\GVimPortable\App\vim\vim73\.
I have a character encoding converter located in d:\Dropbox\Portable
\ConvertZ\ConvertZ.exe
Currently, I use :%!D:\PROGRA~1\ConvertZ\ConvertZ.exe /i:utf8 /o:big5
% to run the converter.
However, when I plug the thumb drive into another computer, the driver
letter of the thumb drive may change to another one.
How do I change the absolute path of convertz.exe to a relative path
referring to $VIMRUNTIME?
You should be able to get the prefix (D:\Dropbox\Portable) by using:
let $PORTABLE = fnamemodify($VIMRUNTIME, ':h:h:h:h')
You might need to change the number of :h's. There may also be fewer
:h's if you use $VIM instead of $VIMRUNTIME.
Then your command can become:
:%!$PORTABLE\ConvertZ\ConvertZ.exe /i:utf8 /o:big5
You may also wish to add ':8' to the modifiers, so that you get a
filename that will never have spaces in it.
See:
:help fnamemodify()
:help filename-modifiers
