IDEs: Eclipse and Emacs

[gusl]

The Eclipse feature that I most miss in Emacs modes is being able to jump to a function's definition/implementation.

(I'm also fond of that refactoring thing in which you can select code to go into a specialized function/procedure. But that hasn't come up yet.)

UPDATE: and the good old call hierarchy! ...which sometimes had too much branching. Please don't show me calls to print().

Try ctags?

Thanks. What's a tag file?

It looks like R isn't supported...

[puellavulnerata.livejournal.com]

A tag file is an index of source code; ctags/etags generates it and emacs interprets it so you can jump to a given symbol. You'd add a makefile rule and then just say something like make tags to update the tag file.

I don't know about R support, though

Thanks.
Eclipse doesn't require running 'make' to tag files, but I suppose it can't be too hard to get Emacs to run 'make tags' every 30 seconds or so.

Do you seriously add a new function and forget where you defined it every 30 seconds?

I used ctags/etags for a C project a while back, along with Eli Barzilay's emacs environment, with great success. I think we threw the etags generation statement into the buildfile, so that it'd run whenever I did a syntax check. Mapped it to C-., worked well.

Oh yeah and the reason why this worked better is because I do believe running etags can be a bit time consuming (i.e. not instantaneous)
