Created on 10 Oct 2018  ·  3Comments  ·  Source: hlissner/doom-emacs

Observed behavior

yasnippets candidates do not present in company autocomplete.
Though I can see them from SPC s i, and expend them nicely.
the result of describe-variable for company backends is shown in the following screenshot

Expected behavior

when I input ifm, autocomplete should presents candidates of ifmain for me.

After checking the codes of doom, I find the company backend is modified here: https://github.com/hlissner/doom-emacs/blob/develop/modules/lang/python/config.el#L64

To enable company-yasnippet by default, the following codes works.

(after! anaconda-mode
  (set-company-backend! 'anaconda-mode '(company-anaconda company-yasnippet)))

This is to be expected. Company will only use company-anaconda. (:separate company-capf company-yasnippet) is a fallback, in case anaconda fails.

You can either access snippet completion through C-x C-s, or by changing python's backends:

(set-company-backend! 'anaconda-mode '(company-anaconda company-yasnippet))

This will change company-backends to be:

((company-anaconda company-yasnippet)
 (:separate company-capf company-yasnippet)
 company-capf)

In python-mode.
