show-config may print default values

[Papp Gyozo (VBuster)]

Hi everyone out there,

I have just a quick but probably add to gengetopt now. Now we have a shiny _dump() function to print all *given* options to an output stream.  Now I come up with the idea that this funciton be able to print default values as well if it is required.

The reason behind that is my application fills some of the default values at runtime which could not be compiled into the source like the actual value of TEMP environmental variable. (These default values can be overriden by the user, of course) This way I, and what would be more important, the users as well could see easily what went wrong.

Hi there

I'm not sure I understad: do you just need that if an option contains
the default value it should be dumped anyway, am I right?

cheers

yes, something like that. Actually I'm talking about to extend the current condition selecting options to be dumped:

  if (args_info->help_given)
    write_into_file(outfile, "help", 0, 0 );

to something like that:

int
<parser>_dump(FILE *outfile, struct cmdline_options *args_info, int dumpall)
(...)
  if (dumpall || args_info->help_given)
    write_into_file(outfile, "help", 0, 0 );

`dumpall' argument may not be the best or ultimate choice. I rather need if *_orig differs from the actual *_arg, but chances are this kind of check makes no sense in certain cases or too difficult to implement (multiple string choices brr)... and it may be too particular request.

Anyway please think of it! :)
