rustop
Introduction
A simple command line parser.
rustop
is a simple command line parsing crate in the spirit of Ruby's
trollop. It allows to write command
line parameters in a type-safe way with as little effort as possible.
rustop
does not aim to be a full-featured command line parser for complex
cases but to be a simple, easy to use crate for programs with a simple set
of command line options.

opt verbose:bool, desc:"Be verbose."; // a flag -v or --verbose
opt luck:bool=true, desc:"We have no luck."; // a flag -l or --no-luck
opt number_of_lines:usize=1,
desc:"The number of lines."; // an option -n or --number-of-lines
param file:Option<String>, desc:"Input file name."; // an optional (positional) parameter
}.parse_or_exit();

}
if let Some(file) = args.file { println!("Read file: {}", file); }
