Minimist.re
A no-frills cli argument parser for reason, inspired by minimist and yargs.
Example usage
(from pack.re):
let parse = Minimist.parse(~alias=[("h", "help")], ~presence=["help"], ~multi=["rename"], ~strings=["base"]); let help = {|# pack.re - a simple js bundler for reason Usage: pack.re [options] entry-file.js > bundle.js --base (default: current directory) expected to contain node_modules --rename newName=realName (can be defined multiple times) maps `require("newName")` to a node_module called "realName" -h, --help print this help|}; let fail = (msg) => { print_endline(msg); print_endline(help); exit(1);}; let args = List.tl(Array.to_list(Sys.argv));/* Some example args for you */let args = ["--base", "awesome", "some-entry.js"]; switch (parse(args)) {| Minimist.Error(err) => fail(Minimist.report(err))| Ok(opts) =>if (Minimist.has("help", opts.presence)) { print_endline(help); exit(0);} else switch (opts.rest) { | [] => fail("Expected entry file as final argument") | [entry] => { let base = Minimist.get(opts.strings, "base"); let renames = Minimist.multi(opts.multi, "rename"); print_endline("All good!") } | _ => fail("Only one entry file allowed")}};
