W.r.t. help strings, I would prefer if we could instead use:
getopt(args,
"timeout|t", &timeout, "Set the timeout",
"other", &other, // note: no comment!
"flag|f", &flag, "Set the flag")
I think we could make getopt support this. For example:
["foo", &foo] => name, field
["foo", &foo, "foo text"] => name, field, #3 is a comment
["foo", &foo, "foo text", "bar", &bar] => #3 is a commen
["foo", &foo, "foo text", &bar] => #3 is a new name
Essentially all getopt has to do is slice up the arguments into
groups, where an address and the string before it begin a new group.
@Andrei: What do you think?
Could we get some form of API to set a header and footer that is printed
with the help text. Possible idea:
bool help;
getopt(args, "h|help", &help, @doc("Show this message and exit.");
getopt.header = "Usage foo [options]\nVersion 0.0.1\n\n";
getopt.footer = "\n\nUse the 'h' flag for help.";
Will print:
Usage foo [options]
Version 0.0.1
Options:
-h, --help Show this message and exit.
Use the 'h' flag for help.
