jump to referenced controller method

this would be a great feature to have! Do you know if we can use ensime to do this?

[bomgar]

I would love an integration with ensime. It probably should be an optional dependency.

Thanks for the response @bomgar.
I would like to make this happen. Do you have an idea where to start?
I'm a newbie to elisp

[bomgar]

My first idea was to integrate with the ensime-search feature and let ensime display the results. But this is more of a hack.
The other option would be to identify the matching part in the compiled routes file end tell ensime to go from there.
I'm not really sure how to approach this. @fommil do you have any input on this?

As for the optional dependency part you can have a look at the ensime-helm integration.

ensime would need a scala source file to be able to correctly know the FQN, but if you know the classname or something you could forward to ensime-search.

I don't really know play very well... can you do string based search?

You could add a rule for parsing routes strings into ctags if it's regular enough.

[bomgar]

The play routes file compiles to a scala file. Ensime should be able to process this. I don't know if ensime indexes generated sources.

[bomgar]

String based ensime-search is also possible because we know the class and method name in the routes file. This could be good enough.

Best-effort search on the class name and feeding it into ensime-search sounds like a good starting point.

Getting the right class and method without compiling will be pretty hard though because the class can be in a package structure and the method can be arbitrarily nested inside the class (or even imported from somewhere else).

Now that I think of it an even better solution could be to C-c C-v v (symbol search) with ensime on just the method name and jump there (1 search hit) or drop the user into helm/ido (2+ search hits).
Determining the "apply thing" name (usually a method) should be really trivial with a regex on the line
