add_builtins() funcname

[Kappa007]

Eggdrop defines following structure:

Code: Select all

typedef struct {
  char *name;
  char *flags;
  Function func;
  char *funcname;
} cmd_t;

"name" is the command name bound to the TCL interpreter.
"flags" are the flags required to trigger the callback "func".
But what purpose does "funcname" serve?

Can you see the string defined there anywhere?


After a grep over all files all I could find about it was in add_builtins/rem_builtins:

Code: Select all

    egg_snprintf(p, sizeof p, "*%s:%s", tl->name,
                 cc[i].funcname ? cc[i].funcname : cc[i].name);

Which just sets it to name if it's not set.

it has probably been added with the idea of aliasing, but later abandoned

Actually it's not abandoned at all.
After looking around in tclhash.c for some hours I found it at another place: It tags the function in the Tcl subsystem.

When checking ".binds" you find the string passed here

Code: Select all

pub  -|-      !help                   0 *pub:<funcname>

That is only if the string is not empty otherwise the "name" of the "cmt_t" struct is passed.

It also shows up in the "tcl_cmd_t" struct as "func_name" which looks like "*<table>:<funcname>".
That's pretty handy if one wants to modify the arguments of a particular command (in check_tcl_bind()).
