About the fix for the interference between Company mode and Yasnippet

emacs, plugins

Solution

The snippet you mentioned doesn't work any more anyway.

Here's a snippet that you can use instead:

(defun company-yasnippet-or-completion ()
  (interactive)
  (let ((yas-fallback-behavior nil))
    (unless (yas-expand)
      (call-interactively #'company-complete-common))))

To make sure that this is called instead of `company-complete-common`, use

(add-hook 'company-mode-hook (lambda ()
  (substitute-key-definition 'company-complete-common
                             'company-yasnippet-or-completion
                             company-active-map)))

Background: This locally changes the value of `yas-fallback-behaviour`, which causes yas to call `company-complete-common` if no completion is found.

Problem

Emacs wiki says: Company does interfere with Yasnippet’s native behaviour. Here’s a quick fix: http://gist.github.com/265010 The code is the following: ``` (define-key company-active-map "\t" 'company-yasnippet-or-completion) (defun company-yasnippet-or-completion () (interactive) (if (yas/expansion-at-point) (progn (company-abort) (yas/expand)) (company-complete-common))) (defun yas/expansion-at-point () "Tested with v0.6.1. Extracted from `yas/expand-1'" (first (yas/current-key))) ``` I placed that code in my .emacs and the following message appeared: ``` Warning (initialization): An error occurred while loading `c:/Documents and Settings/Alex.AUTOINSTALL.001/Application Data/.emacs.elc': Symbol's value as variable is void: company-active-map To ensure normal operation, you should investigate and remove the cause of the error in your initialization file. Start Emacs with the `--debug-init' option to view a complete error backtrace. ``` Do I have to place the fix code inside a YASnippet's .el file? or in my .emacs (which throws me an error)?
