A getopt-like command-line parser for the Rust language
This Rust language library crate implements a Posix getopt-like
command-line option parser with simple programming interface. More
specifically the parser is like getopt’s GNU extension called
getopt_long which is familiar command-line option format for users of
Linux-based operating systems.
The name is Just Getopt because this is just a getopt parser and (almost) nothing more. The intent is to provide just the parsed output and methods for examining the output. There will not be anything for interpreting the output or for printing messages to program’s user. The responsibility of interpretation is left to your program.
In getopt logic there are two types of command-line options:
- short options with a single letter name (
-f) - long options with more than one letter as their name (
--file).
Both option types may accept an optional value or they may require a value. Values are given after the option.
The crate is available at Github and crates.io and it can added
to a Rust project with command cargo add just-getopt.
Documentation is available at docs.rs. From the source code
directory the documentation can be built and shown in a web browser with
command cargo doc --open.
Also see file examples/basic.rs for basic programming examples.
