Add useful development assertion When debugging snippets after M-x toggle-debug-on-error, errors in the `post-command-hook' might cause `yas--post-command-handler' to be removed. That's OK, always check that it's there before attempting any `yas-expand-snippet' calls, since it is essential to check snippet movement. * yasnippet.el (yas-expand-snippet): Assert `yas-minor-mode' and `yas--post-command-handler' active. --- yasnippet.el | 4 ++++ 1 files changed, 4 insertions(+), 0 deletions(-) diff --git a/yasnippet.el b/yasnippet.el index 2a2254b..95c96e4 100644 --- a/yasnippet.el +++ b/yasnippet.el @@ -3490,6 +3490,10 @@ The error should be ignored in `debug-ignored-errors'" Text between START and END will be deleted before inserting template.
