Activate plugin only if executable is installed #1251

Closed mathomp4 closed 12 months ago

mathomp4 commented 12 months ago

This is just a question as I'm trying to be an elegant/better user of vim-plug rather than just hacking my way along. To wit, I recently learned about minimap.vim which requires code-minimap to be installed. Now, the author says you can do:

Plug 'wfxr/minimap.vim', {'do': ':!cargo install --locked code-minimap'}

but, well, I don't want to do any cargo install on some of the systems I run on. But, you can just install code-minimap, put it in the path, and all is well.

So, what I'd like to do is only use the plug if the executable is installed. I'm currently doing this by:

if executable('code-minimap')
    Plug 'wfxr/minimap.vim'
endif

which seems to work just fine. But I wondered "Is there a more elegant way of doing this?" vim-plug has all those cool Plug options that I'd like to learn. I tried reading the FAQ and wiki but I couldn't see anything, so apologies if this is a FAQ.

I think the solution is already elegant and expressive. vim-plug tries to avoid reinventing the wheel, i.e. if you can do something natively without an option, we probably shouldn't provide the option.
