RE: CONTRIB: recursive search in files of the current JDE project

[Mark Bucciarelli]

As someone who's thought about learning elisp, I'd say your first effort
sets a high standard!  :)

I have a suggested modification:  I think the line

   "find %s %s -type f | xargs grep %s -n \"%s\""

is improved by this

   "find %s %s -type f | xargs grep %s -n \"%s\" /dev/null"

(not sure if you need to escape the slashes.)

This way, grep won't miss any hits in the last file that find produces.

Also, I think there is a way to handle file names with spaces in them by
using a print0 argument to find, but I have never been able to get that to
work on my NT / cygwin box.

 Subject: CONTRIB: recursive search in files of the current 
 JDE project 
 
 
 Hello,
 
 I eventually got some time to spend learning emacs-lisp (by 
 the way the
 elisp-introduction available at
 http://www.gnu.org/manual/emacs-lisp-intro/emacs-lisp-intro.html is
 really a great document to start learning elisp), and finally started
 implementing a new feature that I had been wishing the JDE to have.
 
 So attached, it my first lisp function to search a string into all of
 the current JDE project files. It is merely a customization of the
 standard "grep" command to use the JDE customization variables (mainly
 the path to the source files). Please let me know what you 
 think and how
 to improve it!
 
 To use it, include the file in your .emacs file (after 
 loading the jde)
 and type "M-x jde-grep-find"
 Its behavior can be customized, type "C-h f jde-grep-find" 
 for details.
 
 Cheers,
 
 Guillaume.

joel, 

Oups, sorry about that, I had not restarted by emacs since I tested it and so the 
default value of the jde-grep-file-regexp variable was never reassigned. I quoted it, 
I hope it works better now. I learned one more "always test your stuff from a fresh 
emacs process" :-)

Here is the updated version, let me know if this works for you.

Thanks for your feedback,

Guillaume.

 I have had the debug-on-error set to true all the time, but I 
 don't get
 a trace from this error...
 
 sorry,
 
 joel

  Hum... I'm sorry to read this. I'm lacking a stack trace to 
  debug this problem as it does not appear on my machine.
  
  Could you please add the following statement before the 
  load-file so that emacs dumps a stack trace:
  (setq debug-on-error t)
  
  elisp intro provides more info about this at:
  http://www.gnu.org/manual/emacs-lisp-intro/html_chapter/emacs-
  lisp-intro_18.html#SEC196

Joel,

Can you try it using 

(load-file "path to file/jde-grep.el") instead of (require 
'jde-grep)

I did not declare this as a feature so I'm not sure that 
"require" would work. Tell me if this solves your problem.

Thanks,

Guillaume.
