Function Documentation

jim_debug_argv_string()

const char* jim_debug_argv_string	(	Jim_Interp *	interp,
		int	argc,
		Jim_Obj *const *	argv
	)

Debug: convert argc/argv into a printable string for printf() debug.

Parameters

interp	- the interpreter
argc	- arg count
argv	- the objects

Returns

string pointer holding the text.

Note, next call to this function will free the old (last) string.

For example might want do this:

fp = fopen("some.file.log", "a");
fprintf(fp, "PARAMS are: %s\n", Jim_DebugArgvString(interp, argc, argv));
fclose(fp);

jim_getopt_nvp_unknown()

void jim_getopt_nvp_unknown	(	struct jim_getopt_info *	goi,
		const struct jim_nvp *	lookup,
		int	hadprefix
	)

Create an appropriate error message for an NVP.

Parameters

goi	- options info
lookup	- the NVP table that was used.
hadprefix	- 0 or 1 if the option had a prefix.

This function will set the "interp->result" to a human readable error message listing the available options.

This function assumes the previous option argv[-1] is the unknown string.

If this option had some prefix, then pass "hadprefix = 1" else pass "hadprefix = 0"

Example:

 while (goi.argc) {
    // Get the next option
    e = jim_getopt_nvp(&goi, cmd_options, &n);
    if (e != JIM_OK) {
         // option was not recognized
         // pass 'hadprefix = 0' because there is no prefix
         jim_getopt_nvp_unknown(&goi, cmd_options, 0);
         return e;
    }
 
    switch (n->value) {
    case OPT_SEX:
         // handle:  --sex male | female | lots | needmore
         e = jim_getopt_nvp(&goi, &nvp_sex, &n);
         if (e != JIM_OK) {
              jim_getopt_nvp_unknown(&ogi, nvp_sex, 1);
              return e;
         }
         printf("Code: (%d) is %s\n", n->value, n->name);
         break;
    case ...:
         [snip]
    }

	)
