Difficulty with Packages

[Matthew Desjardins]

I've been trying to get packages to work, but I'm having difficulties with the resulting 'runtimepath'. Packages are all added after my own "after" directory, which I would have assumed would be at the end to allow me to override things.

Am I missing something?

[Bram Moolenaar]

What is supposed to happen is that the package directory is added just
after the entry in 'runtimepath' where it that package was found.

For example, the 'rtp' starts as:
~/.vim,/usr/lib/vim/vim74/runtime,~/.vim/after

And when finding the matchit plugin it becomes:
~/.vim,/usr/lib/vim/vim74/runtime,/usr/lib/vim/vim74/runtime/pack/dist/opt/matchit,~/.vim/after

Or when finding a package under ~/.vim:
~/.vim,~/.vim/pack/my/start/demo,/usr/lib/vim/vim74/runtime,~/.vim/after


Can you give a small example of what you are doing and what you see
happens?

packadd-ing an opt is fine, but something under a start is appended to my runtimepath:

C:\Users\desjardinsm/vimfiles,C:\Program Files\Vim/vimfiles,C:\Program Files\Vim\vim74,C:\Program Files\Vim\vim74\pack\dist\opt\matchit,C:\Program Files\Vim/vimfiles/after,C:\Users\desjardinsm/vimfiles/after,C:/Users/desjardinsm/vimfiles/pack/test/start/test

Looks like a forward/backward slash mixup problem.

Can somone using Windows reproduct this and find out what is the best
way to fix it?

I don't think that mixes slashes is the problem. I have mixed slashes in my runtimepath, and it works fine. Windows happily uses either kind (or even both) without caring.

[Bram Moolenaar]

That works fine for using the 'rtp', that's why there can be a mix.
But when finding the spot to put the new path in strstr() is used, which
doesn't ignore the difference. This is in add_pack_plugin().

No suggestions on a fix, but thanks for the pointer! This workaround, placed at the beginning of my .vimrc, lets Vim put package directories in the correct location for now:

if has('win32')
let &runtimepath=substitute(&rtp, '/', '\\', 'g')
endif

Interestingly, going the other way (changing from backslash to forward slash) does not work, even with 'shellslash' set.
