Readme

cli-usage
Easily show the usage of your CLI tool from a Markdown string or file. You can just plug cli-usage in without thinking about paramters, or you can handle that your self using the .get API end-point.

Install

npm install cli-usage

Usage

Most basic usage, just plug in:
var usage = require('cli-usage');
usage();
//=> If help-flag is passed, print usage
//=> and exit with code 0.

This will listen for -h, -help or --help passed into your CLI and try to locate a usage.md file from the directory of the file. If help is passed and the usage.md file found, the usage will be printed and the application will exit with code 0.
You can also pass in a filename or a string.
var usage = require('cli-usage');
usage('./some/path/to/usage.md');

or
var usage = require('cli-usage');
usage('# Simple usage');

Get compiled usage

Instead of cli-usage doing all the work, you can also just retrieve the compiled usage text and handle it your self.

Example

var usage = require('cli-usage');

console.log(usage.get('# some custom markdown from string'));

console.log(usage.get('./usage.md'));
