Open a file at line with "filename:line" syntax

You can do this using emacsclient. e.g. to open FILE at line 4, column 3 in a new frame:

emacsclient +4:3 FILE

Leave off the :3 to simply open the file at line 4.

I have the following in my .emacs, but I haven't found it as useful as I thought it would be.

;; Open files and goto lines like we see from g++ etc. i.e. file:line#;; (to-do "make `find-file-line-number' work for emacsclient as well");; (to-do "make `find-file-line-number' check if the file exists")(defadvice find-file (around find-file-line-number                             (filename &optional wildcards)                             activate)  "Turn files like file.cpp:14 into file.cpp and going to the 14-th line."  (save-match-data    (let* ((matched (string-match "^\\(.*\\):\\([0-9]+\\):?$" filename))           (line-number (and matched                             (match-string 2 filename)                             (string-to-number (match-string 2 filename))))           (filename (if matched (match-string 1 filename) filename)))      ad-do-it      (when line-number        ;; goto-line is for interactive use        (goto-char (point-min))        (forward-line (1- line-number))))))

And here is my go at it. Calls the original find-file-at-point

(defun find-file-at-point-with-line()  "if file has an attached line num goto that line, ie boom.rb:12"  (interactive)  (setq line-num 0)  (save-excursion    (search-forward-regexp "[^ ]:" (point-max) t)    (if (looking-at "[0-9]+")         (setq line-num (string-to-number (buffer-substring (match-beginning 0) (match-end 0))))))  (find-file-at-point)  (if (not (equal line-num 0))      (goto-line line-num)))
