When I use yasnippet, I keep getting this error:
Warning (yasnippet): `foo-snippet' modified buffer in a backquote expression.
To hide this warning, add (yasnippet backquote-change) to `warning-suppress-types'.
I added this line to my config:
(setq warning-suppress-types (quote ((\(yasnippet\ backquote-change\)))))
But it doesn't seem to have worked.
warning-suppress-types is a list defined in the warnings package. You first need to load this package with:
(require 'warnings)
and after this, add the warning using add-to-list:
(add-to-list 'warning-suppress-types '(yasnippet backquote-change))
Debugger entered--Lisp error: (void-variable warning-suppress-types) (member (quote (yasnippet backquote-change))

M-x describe-variable <ret> warning-suppress-types <ret>?
(eval-after-load 'warnings ...), or needs a (require 'warnings) first.
Alternate answer is to fix foo-snippet so that it no longer modifies the buffer in backquote expression. See https://emacs.stackexchange.com/a/24062/5296 for some examples.
Also note that there was a bug causing yasnippet to issue this warning even when other buffers were being modified, so make sure you have the latest yasnippet (or else the current stable release (0.10) which doesn't have this warning at all). See https://github.com/joaotavora/yasnippet/issues/716
