Modifying many function calls

Modifying many function calls

[Andrea Crotti]

I would like to finally prepend a prefix to all my personal functions.
Since they are 80 at the moment I would like to do it automatically.

For the (defun fun) part is easy, but what about all the places when
they are called?

I should loop on all the
(defun fun) and substitute all the occurrences of fun every time, what's
the best way to do it with Emacs?

Thanks,
Andrea

I was also seeing if semantic can help, but if I go on any of the
functions and I try
M-x RET semantic-symref, I don't anything, even if there are actually
calls to that function and semantic is working fine.

You could use `make-obsolete' on the old symbol and `defalias' to make
the new one.  Then byte-compiling will warn about the obsolete function.

Personally I would just use `grep' or `ack' coupled with 
"perl -p -i -e's/OLD/NEW/g' *.el" coupled with version control :)

the easiest but perhaps not the best is replace-string there is also
some command that can do the same but recursing on a dir, i dont
remember which.

Hi,

wrote years ago the opposite: defining aliases for all prefixed 
functions, The alias then was the function name with prefix turned into 
suffix. Should exist in the gnu-emacs-sources@gnu.org archive somewhere.

Purpose was making completion of function-groups work.
However, would write that differently today probably.

Also, if you give some info here, it should be possible to put the 
script together at this list.

Questions would be:

- reside all files with functions to rename in the same directory?
- really all functions to rename?
- only functions to rename, not variables?

- actually in the same big org-mode file (unless I call something from
  some yasnippet snippet, but I don't think)
- yes maybe also variables
  But variables can be assigned to a group also (with defcustom) so it's
  not so bad
- yes really all functions (some have the "my-" prefix but that can be
  changed easily I think)

And since I'm here, why I can't redefine a variable with defcustom?
I mean if I do

(defcustom x 1)
then I want to change it
and I write and evaluate
(defcustom x 2)

then even if I set it to nil and the reevaluate again still it doesn't
care.
Is that normal?

AFAIK yes. It's little bit like with `defvar', but not that strictly, 
rather unpredictable.

Use `setq', resp. a setq afterwards to make sure the new value is taken.

(?) assume "directory"

In any case, suggest to move your functions into a separate directory or 
file.
That would make things much easier.

Unless there are reason not to do this.

If in a directory, first task is to get a list of files.
Function below as an example messaging in:

(defun load-files-from-directory (&optional dir)
   (interactive)
   (let* ((dir (or dir default-directory))
         (files (directory-files (expand-file-name 
(substitute-in-file-name dir)) t "\\.el$")))
     (message "%s" files)))

If just one file, its even easier, we proceed there.

You need to use eval-defun on defvar's and defcustom's, bound to C-M-x by default.

redefining/re-evaluating a defcustom [was: Modifying many function calls]

I think it's completely predictable. Yes, it's like `defvar'.

Interactively, you can just put point inside the defcustom somewhere and hit
`C-M-x'.

If the user has already customized x to some value (nil or anything
else), then you don't want the default value to overwrite it.  So
defcustom avoids setting the value if it's already been set.

(Note that if x is a buffer-local variable with no global value,
defcustom will set the global default value without changing the local
value.)
