[Bug] `hg` command not found

[alexmozaidze]

I don't have hg installed, and whenever I try to fuzzy search it gives an error (every time), and after I hit enter it works fine. I found solution to the problem, that is to manually set g:fuzzy_rootcmds to only have the programs you have on the system (for me it's git).

Hmm strange. The second command is only called if the first one fails, which uses git.

Thanks @alexmozaidze I had the same problem on the new Apple M1 Max Macbook. I set this in my init.vim: let g:fuzzy_rootcmds = [ \ ["git", "rev-parse", "--show-toplevel"], \ ] with the original being https://github.com/cloudhead/neovim-fuzzy/blob/0bef4e1a81c65fc05d31380dd74454bd67733837/plugin/neovim-fuzzy.vim#L34-L37

I didn't have hg or root installed.

This worked for me (in init.lua): vim.cmd('let g:fuzzy_rootcmds = [ ["git", "rev-parse", "--show-toplevel"] ]')

This worked for me (in init.lua): vim.cmd('let g:fuzzy_rootcmds = [ ["git", "rev-parse", "--show-toplevel"] ]')

I'm also using vim with init.lua config file, and it has worked very well for me.

@cloudhead

If you perform :FuzzyOpen outside a git repository, git rev-parse --show-toplevel fails. After that, hg root gets called. git rev-parse --show-toplevel is run, returns an error and is handled properly, while hg root cannot be run since hg is does not exist and so system(cmd) throws.

My guess is that the function should use executable(cmd) ([doc](https://vimdoc.sourceforge.net/htmldoc/eval.html#executable())) before calling system(cmd)

[cloudhead]

Hmm yeah, that makes sense!
