kme : argumentparsing   13

adishavit/argh: Argh! A minimalist argument handler.
It doesn't get much simpler than this:
<code class="language-cpp">
#include <iostream>
#include "argh.h"

int main(int, char* argv[])
{
argh::parser cmdl(argv);

if (cmdl[{ "-v", "--verbose" }])
std::cout << "Verbose, I am.\n";

return EXIT_SUCCESS;
}</code>

python - Control formatting of the argparse help argument list? - Stack Overflow | https://stackoverflow.com/
Still wraps the help text to 80 columns, I think, rather than the terminal width.

I like this solution of putting all the arguments in a list, though.
You could supply formatter_class argument:
<code class="language-python">parser = argparse.ArgumentParser(prog='tool',
formatter_class=lambda prog: argparse.HelpFormatter(prog,max_help_position=27))

args = [('-u', '--upf', 'ref. upf', dict(required='True')),
('-s', '--skew', 'ref. skew', {}),
('-m', '--model', 'ref. model', {})]
for args1, args2, desc, options in args:
parser.add_argument(args1, args2, help=desc, **options)

parser.print_help()</code>

Processing command line arguments - @ARGV in Perl | https://perlmaven.com/
Oh, so $ARGV[0] is actually argv(1). Nice.

You want "$0" instead.
In case you know the C programming language, this is similar to argv, except that the @ARGV of Perl does not contain the name of the program. It can be found in the $0 variable. Also a variable such as argc is not necessary, as you can easily get the number of elements in the @ARGV array using the scalar function or by putting the array in scalar context.
