/** * Command line arguments parser based on * {@link https://github.com/minimistjs/minimist | minimist}. * * See {@linkcode parseArgs} for more information. * * @example Usage * ```ts * import { parseArgs } from "@std/cli/parse-args"; * import { assertEquals } from "@std/assert/equals"; * * // For proper use, one should use `parseArgs(Deno.args)` * assertEquals(parseArgs(["--foo", "--bar=baz", "./quux.txt"]), { * foo: true, * bar: "baz", * _: ["./quux.txt"], * }); * ``` * * @example `string` and `boolean` options * * Use `string` and `boolean` options to specify the type of the argument. * * ```ts * import { parseArgs } from "@std/cli/parse-args"; * import { assertEquals } from "@std/assert/equals"; * * const args = parseArgs(["--foo", "--bar", "baz"], { * boolean: ["foo"], * string: ["bar"], * }); * * assertEquals(args, { foo: true, bar: "baz", _: [] }); * ``` * * @example `collect` option * * `collect` option tells the parser to treat the option as an array. All * values will be collected into one array.
