Or even set rtp+=~/.vim or set rtp^=~/.vim :)
But I want to insert the ~/.vim/ dir inside &rtp in the right place
before $VIMRUNTIME, and only if it is not included in &rtp already.
set rtp+= ... will not append if already ... is already present
set rtp^= ... will prepend, but will not prepend if ... is already

For this I need to process every dir in &rtp and compare it with
both ~/.vim/ and $VIMRUNTIME. And for this I need the canonical path
names.
Are you worried about whether or not ~/.vim is already in
$VIMRUNTIME? $VIMRUNTIME has already been expanded, so if ~/.vim
duplicates one of the $VIMRUNTIME entries, it won't prepend with ^=
and won'tappend with += .
Ok, than
:set rtp ^= ~/.vim
:set rtp += ~/.vim
will take care of any duplicates.
But if ~/.vim is not already in &rtp, that it will be prepended (or
appended) to the entire list, and that is not what I want. I would
like to insert it in the list right before $VIMRUNTIME.
(by the way, $VIMRUNTIME is not &runtimepath, it is only one of the
directories in &runtimepath, and it usually appears there in the
middle of the list).
Right, so is there any reason you don't have control over what's being
added to &rtp?
I.e. If you're using some kind of plugin management, just do:
==> in your .vimrc/_vimrc <==
" 'rtp' contains $VIMRUNTIME by default...
" 'rtp' contains $HOME/vimfiles and $VIM/vimfiles by default...
" this next section might depend on recent changes... (I think vimfiles
" is used if it exists, and .vim otherwise)
"
" if vimfiles exists, it will have been used rather than .vim
" otherwise, &rtp should already contain .vim
if (exists(expand('~/vimfiles')))
" then add ~/.vim before and ~/.vim/after after
se rtp^=~/.vim
se rtp+=~/.vim/after
endif
I believe the order of the directories in &runtimepath is significant.
The fact that Vim has those after/ directories, which are meant to come
last in &runtimepath, shows my point I believe.
Now, since 'runtimepath' is a user setting, that is 'runtimepath' is
meant to be set and modified by the user, not automatically by my
script, than I want to try to make my script as non-intrusive as possible.
That means I want to at least put my directory, which is ~/.vim, in the
right position in &runtimepath, in front of the $VIMRUNTIME directory.
Thank you,
