Is there a shortcut for inserting a <%= %> in Rubymine?
I took a look in keymap and didn\'t see anything.
I'm not sure if there is a shortcut or not, but usually you can just type in the first portion, and rubymine will auto close it. You just have to hit a space after you do the opening. So doing:
<%' ' outputs=> <% /code %>
<%=' ' outputs=> <%= /code %>
And it does this for the rest of the openings.
I show it listed as Cmd-Shift-., but that's also mapped to folding. I remapped mine to Cmd-Shift-,.
(Plain IntelliJ; RubyMine may vary slightly.)
Here is the plugin to make this work very easy. link
The default shortcut is Ctrl+Shift+Period on Windows and Cmd+Shift+Period on Mac. It may not work on all the keyboards, in which case you can change it in Settings (Preferences on Mac) | Keymap: Main Menu, Tools, Erb, Insert <%= %>:

You can also use code completion:

After accepting this choice you'll get:
<%= | %>
Another option is to define a live template:

Type re, then Tab to expand.
Finally, you can define a keyboard shortcut for any text/template using the following trick:
Edit | Macros | Start Macro Recordingre, then TabEdit | Macros | Stop Macro RecordingRubyExpression nameNow go to Keymap settings and assign a shortcut to RubyExpression under Edit, Macros.
