Textmate 2 Ruby on Rails 捆绑包：某些片段不再适用于 macOS Big Sur（所有已发布版本），例如 hm \tab

Question

On a fresh install of Big Sur (updated all the way to 11.3.1) with a Rails 6 project I noticed that some snippets will not autocomplete (eg hm → tab). This happened also on all previous releases of Big Sur. Catalina with a Rails 6 project on the same machine has no issue at all.

When I boot into Big Sur (11.2.1 / 11.3.1) in a Rails 6 project or any file with type set to "Ruby on Rails" and the "Ruby on Rails" bundle installed, no snippet with scope meta.rails.model will tab-complete. I can run them from the bundle menu, however.

The issue presents itself the same as this question How do make snippets work for Ruby On Rails in Textmate 2? , which is fairly old and to which there seems to be no resolution.

I found these instructions on coderwall https://coderwall.com/p/b6j9mw/fix-textmate-code-completion-for-rails-4-models , however they did nothing for me. I quit and restarted textmate, uninstalled, reinstalled, cleaned out the library, however, nothing seems to work.

Anybody ever solved something like this?

Answer 1

I got a tip on #textmates IRC channel.

Pressing control-shift-P in the file that is misbehaving shows you information about the current scope. After that I re-set the language to ruby-on-rails (it had changed to ruby, maybe by pressing the keys above, maybe independently).

Now it works.
