Is there a way to check whether a plugin is installed?

[glyh]

I have the following code in my mapping confs:

nvim.cmd([[
  try
    call arpeggio#map('i', '', 0, 'jk', '<Esc>')
  catch
  endtry
]])

which depends on some specific plugin. I'd like to know if there are other ways to detect whether some plugin is installed? Thanks a lot!

Thumbing up this question. Currently we can only check whether it's loaded or not. Any tips?

I think this solves my problem, thanks.

There is a way to checkout whether some plugin is loadable or not btw:

local ok, mod = pcall(require, "foo/bar")
if ok then 
...
end
