This seems like it should be easy.
I'm creating a CLI command gem, so the command is in bin/gem_name which has no .rb extension. When I try to edit that file in RubyMine, it doesn't give it a language mode (sorry, don't know the proper term) to make syntax highlighting and other niftyness in RubyMine work.
How can I tell RubyMine that this is, in fact, a Ruby file?
回答1:
There are several ways to tell RubyMine that a file is of a particular type:
Begin the command file with a hashbang line that RubyMine recognizes as being Ruby. I don't know what exactly it recognizes, but all of the scripts that gems put in to my bin dir begin with
#!/usr/bin/env rubyand when I make a new script which begins with that line RubyMine also recognizes it as being Ruby (even before I open it). I did notice that when I had a file without this line and then added it I had to quit and restart RubyMine for it to take effect.
Just open the file in RubyMine. When I open a file that RubyMine doesn't recognize, it asks me what type it is and remembers what I tell it.
Register the file manually:
- Go to Preferences -> IDE Settings -> File Types
- Under File Types, select "Ruby files"
- Under Registered Patterns, add a new pattern that matches
gem_name
It would be painful to have to do this for a lot of files, but it might be useful in some cases.
I'm surprised that method 2 didn't work for you already. Maybe you told RubyMine that the file was a text file. Check the Text file type in the File types preferences to be sure your file isn't registered as text.

Right click on the filename in the project view.
Select "Associate with File Type..."
Select "Ruby"
