elisp compile, add a regexp to error detection
- by Gauthier
I am starting with emacs, and don't know much elisp. Nearly nothing, really.
I want to use ack as a replacement of grep.
These are the instructions I followed to use ack from within emacs:
http://www.rooijan.za.net/?q=ack_el
Now I don't like the output format that is used in this el file, I would like the output to be that of ack --group.
So I changed:
(read-string "Ack arguments: " "-i" nil "-i" nil)
to:
(read-string "Ack arguments: " "-i --group" nil "-i --group" nil)
So far so good.
But this made me lose the ability to click-press_enter on the rows of the output buffer. In the original behaviour, compile-mode was used to be able to jump to the selected line.
I figured I should add a regexp to the ack-mode. The ack-mode is defined like this:
(define-compilation-mode ack-mode "Ack"
"Specialization of compilation-mode for use with ack."
nil)
and I want to add the regexp [0-9]+: to be detected as an error too, since it is what every row of the output bugger includes (line number).
I've tried to modify the define-compilation-modeabove to add the regexp, but I failed miserably.
How can I make the output buffer of ack let me click on its rows?
--- EDIT, I tried also: ---
(defvar ack-regexp-alist
'(("[0-9]+:"
2 3))
"Alist that specifies how to match rows in ack output.")
(setq compilation-error-regexp-alist
(append compilation-error-regexp-alist
ack-regexp-alist))
I stole that somewhere and tried to adapt to my needs. No luck.
