Using a File index

Using a File index

[HS]

Hi all
I use to open files using recursive find.
Now I just did a ruby script to generate a list of all sources on some
given folder.
My problem now is to parse this file and use it to open the file I'm
looking for.

file1.c = c:\blabla\prj1\file1.c
file2.c = c:\blabla\prj2\file2.c
file3.c = c:\srcs\file3.c

Anyone could give me a hint?
Thanks in advance!

I think the answer is in the shell, not Emacs:

emacs $(ruby SCRIPT FOLDER | awk -F= '{print $2}')

That's nice, but it's solved now.
That solution of yours wouldn't open a new emacs?
And also I don't have awk here :) (winxp)
Tks anyway

So use emacsclient instead of emacs.

How was it solved?

With this code:
(defun indexed-find (file)
  (interactive "MFilename: ")
  (find-file "my_file_index.txt")
  (if (re-search-forward (concat file " = ") nil t 1)
	  (progn
		(setq beg (point))
		(end-of-line)
		(setq end (point))
		(find-file (buffer-substring beg end)))
	  (message "File not found!"))
  (kill-buffer "my_file_index.txt"))

The index file was made with a ruby script, and I update it manually
when there are some new files...

I had some free time and could not resist trying out some
alternatives... :)

Alternative 1:

This is basically your code, just written a bit differently:

(defun indexed-find-2 (file)
  (interactive "MFilename: ")
  (with-temp-buffer
    (insert-file-contents "my_file_index.txt")
    (if (search-forward-regexp (format "%s = \\(.*\\)" file) nil t)
        (find-file (match-string 1))
      (message "File not found!"))))

You might want to use the full path or a variable in the file
name above.

Alternative 2:

Another way to do what you want, using completion.

(defun indexed-find-3 ()
  (interactive)
  (let* ((file-data 
         (with-temp-buffer
           (insert-file-contents "my_file_index.txt")
           (buffer-substring (point-min) (point-max))))
         (rows (split-string file-data "\n"))
         (file (completing-read "File: " rows)))
    (if (string-match "\\(.*\\) = \\(.*\\)$" file)
        (find-file (match-string 2 file))
      (message "Could not find a file on that row"))))

Or, same code, but a but harder to read maybe:

(defun indexed-find-4 ()
  (interactive)
  (let ((file (completing-read 
               "File: " 
               (split-string          
                (with-temp-buffer
                  (insert-file-contents "my_file_index.txt")
                  (buffer-substring (point-min) (point-max)))
                "\n"))))
    (if (string-match "\\(.*\\) = \\(.*\\)$" file)
        (find-file (match-string 2 file))
      (message "Could not find a file on that row"))))

> The index file was made with a ruby script, and I update it manually

You might also want to have a look at using Emacs
file-cache (http://www.emacswiki.org/cgi-bin/wiki/FileNameCache)
or similar functionality.

Happy hacking!

Oh, that functionality was already implemented! Why that doesn't
surprise me ? :)
Hey Mathias tks for the alternatives, I'll switch to one of those!!

Oh and I was (am) using a full path for the file name, I just removed
it because I didn't wanted to reveal my path (don't ask me why, i
can't think of a good reason now heh... )

Hmm, thinking about it... those versions without ARG are less
interesting because I can't use them in a function like this, right?

(defun indexed-find-current-word ()
  " Find file under cursor "
   (interactive)
   (indexed-find-3 (current-word)))

(for example if I wanted to follow files by putting the cursor over an
#include <file.h> and hitting some key combination.. just an example)

Right: the call to completing-read should be moved within the
interactive form, to provide the value of the FILE argument _when
called interactively_.
