gulp-match status

Does a vinyl file match a condition? This function checks the condition on the file.path of the vinyl-fs file passed to it.

Condition can be a boolean, a function, a regular expression, a glob string (or array of glob strings), or a stat filter object

Used by gulp-if and gulp-ignore

Usage

var gulpmatch = require('gulp-match');
var map = require('map-stream');

var condition = true; // TODO: add business logic here
var options = null; // Optionally pass options to minimatch

vinylfs.src('path/to/file.js')
  .pipe(map(function (file, cb) {
    var match = gulpmatch(file, condition, options);
    if (match) {
      // it matched, do stuff
    }
    cb(null, file);
  }));

API

file

A vinyl-fs file.

condition

boolean condition

var match = gulpmatch(file, true);

if the condition parameter is true or false, results will also be true or false.

function condition

var match = gulpmatch(file, function (file) {
  return true;
})

if the condition parameter is a function, it will be called, passing in file passed to gulp-match.

regular expression condition

var match = gulpmatch(file, /some\/path\.js/);

If the condition is a regular expression, it will be evaluated on the file.path passed to gulp-match.

glob condition

var match = gulpmatch(file, './some/path.js');
var match = gulpmatch(file, ['./array','!./of','./globs.js']);

The globs are passed to minimatch. If the glob matches (or any of the elements in the array match), gulp-match returns true else false.

stat filter condition

var match = gulpmatch(file, {isFile:true});
var match = gulpmatch(file, {isDirectory:false});

If the condition is an object with a isFile or isDirectory property, it'll match the details on the vinyl-fs file's stat object.

else

var match = gulpmatch(file, 42);
// match = true
var match = gulpmatch(file, '');
// match = false

If there's no matching rule from the rules above, it'll return true for truthy conditions, false for falsey conditions (including undefined).
