Replacing ocurrences of a string...

Replacing ocurrences of a string...

[luca.spinacci]

I generate a C function template in a buffer running a command.
I would like to replace every occurence of the <name> string
on direct request.
Let's say:
M-x my-template-generator

generates in my - C - buffer
a template like

/*
**********************
* <name>
**********************
void <name>()
{


} // <name>

I would like to be prompted for the function name to be replaced with.
Using (query-replace "<name>" "") in "my-template-generator" I have to
call SHIFT-e to be requested for "Edit replacement string: "  and
SHIFT-1 to replace every occurence of <name> with the new string "my-name".
Is there a smarter way (I'm sure there is) to be requested for the
replacement
string ("Edit replacement string: ") automatically as the template is
inserted
in the buffer without using SHIFT-e?
The function query-replace is not mandatory...

Thanks in advance,
Luca.

Usually, this is done by programming correctly my-template-generator:

(defun my-template-generator (funame)
   (interactive "sFunction name: ")
   (insert "/*\n"
           "********************\n"
           "* "funame"\n"
           "********************\n"
           "*/\n"
           "void "funame"()\n"
           "{\n"
           "    \n"
           "}//"funame"\n\n"))

What I think you are looking for is skeletons.  Here's an example from 
my emacs skeletons that I use a lot when writing C code.


(define-skeleton skel-struct-c
   "struct"
   "Struct Name:"
   > "typedef struct " str \n
   "{" > \n
   _ > \n
   "} " str "_t;" > )


That defines a skeleton that asks me for the name of the struct and then 
  inserts that name everywhere "str" appears.  So if I used the skeleton 
above and entered "schmoo" when prompted I'd get:

typedef struct schmoo
{

} schmoo_t;

In addition the cursor ends up inside the struct braces because of the 
'_' character in the skeleton.

To run this skeleton I have the following in my .emacs:

   (define-abbrev c-mode-abbrev-table "st" "" 'skel-struct-c)

Then, when editing code I can type stC-x a e to use the skeleton.  C-x a 
e runs expand-abbrev and the "define-abbrev" tells emacs to use 
skel-struct-c as an abbreviation expansion for the strings "st".
