getopt
Erlang module for parsing command line arguments using GNU getopt syntax with type conversion and environment variable expansion.
What is getopt?
Getopt is an Erlang library that provides command-line argument parsing following the GNU getopt syntax. It enables Erlang applications to handle complex command-line interfaces with support for short and long options, typed arguments, and automatic usage generation.
Erlang developers building command-line tools, escripts, or applications that require robust argument parsing with GNU-style syntax and Erlang type integration.
Developers choose Getopt for its familiar GNU getopt syntax, seamless integration with Erlang's type system for argument validation and conversion, and features like environment variable expansion and automatic help text generation.
