Switch between Rails controller and view in Komodo

Tuesday, May 23rd, 2006

Yesterday I tried radrails, which is quite nice for a free tool. Being a Komodo fan however (thanks to my employer for paying the license) the only obvious advantage for me would be being able to switch between controller and corresponding view.

Because I was getting a bit jealous of this feature in Textmate/RadRails/… I cooked up a way to do the same in Komodo.

How can this work in Komodo ?
When calling external commands (via the Toolbox) in Komodo you can give path + linenumber of current file being edited (amongst others) as parameters. You can start the Komodo binary passing a filename + linenumber, and Komodo is nice enough not to start itself twice or load the same file twice when doing this.
The ‘figuring out what controller/action we’re in and calling the corresponding view‘-part (and vice versa) is handled by a little ruby script. (which could probably be much tighter, but I’m still a ‘ruby nuby’ and if I have to clean it up before publishing it’ll probably never leave my personal Toolbox… so be thankfull I have enough guts and ego to dare publish my dirty code 😉

How to install this script in the Komodo toolbox ?

  • Save the script below (let’s call it ‘open_ctrl_view.rb’) wherever you like to save such things.
    Remember to chmod +x it to make it executable!
  • In open_ctrl_view.rb : Edit the path to your komodo installation, or just put ‘komodo’ if komodo is in your search path.
    Edit the shebang to point to the correct ruby version if necessary.
  • In komodo: add new command in toolbox. As command, enter ‘open_ctrl_view.rb %F %L’ (include full path to whre you saved open_ctrl_view.rb if necessary)
    %F will insert the full path and %L the current line of the file being edited
  • Run in: ‘Command Output Tab’ (default option) and I marked ‘Do not open output pane’ below. If necessary you can always switch to the output pane manually if something went wrong.

Add key binding if necessary (warning: this is a bit buggy in Komodo 3.5.2 but should be fixed in 3.5.3)

Windows users: Probably the same as above, except no need for chmod’ing, and you’ll probably need ‘ruby open_ctrl_view.rb %F %L’ instead as command.
Mac users: Aren’t you using Textmate ?

The script (open_ctrl_view.rb)
No guarantees are made. Your head might explode, ladadi ladada, etc.
I was going to include it as text in this post, but even enclosed in the proper tags it looks all funny, so download it here.

Closing comments…
If you make nice enhancements: let me know! (what about a similar script that loads the model your cursor is positioned on ? Komodo can also send the word your cursor is on as a parameter)
