sandermatch v0.1.4

Sandermatch

Filesystem functions that return filenames matching a minimatch pattern

What

sandermatch is a small javascript library that combines the Promise-based power of sander with the regexp-matching power of minimatch.

How

"Give me all the filenames of all PNG images in /tmp, recursively"

var sandermatch = require('sandermatch');

sandermatch.lsrMatch('/tmp', '**/*.png').then(function(filenames){ console.log(filenames) });

The following functions are exported:

• lsrMatch(...paths, patterns)
• lsrMatchSync(...paths, patterns)
• readdirMatch(...paths, patterns)
• readdirMatchSync(...paths, patterns)

All of them have behaviour like their counterparts in sander, but the return value is not a Promise of an array with all files. Instead, it's a Promise of a Set with the filenames that match one of patterns.

The resulting Set is ordered by the order of patterns, for example:

sandermatch.lsrMatch('.', ['**/*.js', '**/*.png']).then( function (filenames){
	// filenames has all the *.js before any of the *.png files, e.g.
	// - foo.js
	// - bar.js
	// - lib/whatever/whatever.js
	// - logo.png
	// - lib/whatever/assets/whatever.png
} );

Compatibility

sandermatch is coded in ES2016, and transpiles to ES5 but it assumes that the Set datatype exists. Since this is implemented in node 0.12 onwards, it shouldn't be a problem.

Run npm install to transpile to ES5. ES5/ES2015 dependencies should be handled transparently via the main/jsnext:main properties of package.json.

In ES2015 packages:

import { lsrMatch } from 'sandermatch';
lsrMatch(path, pattern).then(doStuff);
