Re: Emacs shows xrefs in code but needs an interface that's good for humans

I use the built-in "occur" when I want to see where things are referenced. It's not smart but usually does its job.

However, I'm just an amateur programmer and my needs of specialist tools may be limited. I don't have to deal with crappy code or work under pressure.

Hey that's neat! Here's an example for anyone that's watching. I'd never seen occur before and had to try it out. Typing `M-x occur "current_balance"` gets me a new pane of info. If I move the cursor to any and hit enter, the source pane will automatically seek there. `5 lines matching "current_balance" in buffer RBCUWatcher2. 23:my $current_balance = eval { 39:exit unless length $current_balance; 41:write_file( BALANCE_FILE, $current_balance ); 43:my $difference = $current_balance - $old_balance; 45: my $message = "\$$current_balance "` [download] ~/bin/BankBalanceWatcher Read more...

I've found this little gem makes occur quite a bit more useful: (defun isearch-occur () "Invoke `occur' from within isearch." (interactive) (let ((case-fold-search isearch-case-fold-search)) (occur (if isearch-regexp isearch-string (regexp-quote isearch-str +ing))))) (define-key isearch-mode-map (kbd "C-o") 'isearch-occur) [download] Then you can isearch to the word you want, hit C-w to grab the rest of it, then C-o to get a list of occurrences.
