Probably the sole command line option parser you'll ever need to <del>`npm install optjs`</del> Ctrl+C, Ctrl+V. Proof:
|
|
|
|
```js
|
|
function opt(argv) {
|
|
var opt={},arg,p;argv=Array.prototype.slice.call(argv||process.argv);for(var i=2;i<argv.length;i++)if(argv[i].charAt(0)=='-')
|
|
((p=(arg=(""+argv.splice(i--,1)).replace(/^[\-]+/,'')).indexOf("="))>0?opt[arg.substring(0,p)]=arg.substring(p+1):opt[arg]=true);
|
|
return {'node':argv[0],'script':argv[1],'argv':argv.slice(2),'opt':opt};
|
|
}
|
|
```
|
|
|
|
Usage
|
|
-----
|
|
```js
|
|
var opt = require("optjs")();
|
|
console.log(opt.node); // Path to node executable
|
|
console.log(opt.script); // Path to the current script
|
|
console.log(opt.opt); // Command line options as a hash
|
|
console.log(opt.argv); // Remaining non-option arguments
|
|
```
|
|
|
|
Example
|
|
-------
|
|
`node somescript.js foo -a=1 -b --c="hello world" bar ----d`
|
|
|
|
```js
|
|
// Result
|
|
opt.node == "/path/to/node[.exe]"
|
|
opt.script == "/path/to/somescript.js"
|
|
opt.opt == { a: 1, b: true, c: "hello world", d: true }
|
|
opt.argv == ["foo", "bar"]
|
|
```
|
