is-glob

Returns `true` if the given string looks like a glob pattern or an extglob pattern. This makes it easy to create code that only uses external modules like node-glob when necessary, resulting in much faster code execution and initialization time, and a bet

Returns true if the given string looks like a glob pattern or an extglob pattern. This makes it easy to create code that only uses external modules like node-glob when necessary, resulting in much faster code execution and initialization time, and a better user experience.

Install

Install with npm:

$ npm install --save is-glob

Usage

var isGlob = require('is-glob');

Default behavior

True

Patterns that have glob characters or regex patterns will return true:

isGlob('!foo.js');
isGlob('*.js');
isGlob('**/abc.js');
isGlob('abc/*.js');
isGlob('abc/(aaa|bbb).js');
isGlob('abc/[a-z].js');
isGlob('abc/{a,b}.js');
//=> true

Extglobs

isGlob('abc/@(a).js');
isGlob('abc/!(a).js');
isGlob('abc/+(a).js');
isGlob('abc/*(a).js');
isGlob('abc/?(a).js');
//=> true

False

Escaped globs or extglobs return false:

isGlob('abc/\\@(a).js');
isGlob('abc/\\!(a).js');
isGlob('abc/\\+(a).js');
isGlob('abc/\\*(a).js');
isGlob('abc/\\?(a).js');
isGlob('\\!foo.js');
isGlob('\\*.js');
isGlob('\\*\\*/abc.js');
isGlob('abc/\\*.js');
isGlob('abc/\\(aaa|bbb).js');
isGlob('abc/\\[a-z].js');
isGlob('abc/\\{a,b}.js');
//=> false

Patterns that do not have glob patterns return false:

isGlob('abc.js');
isGlob('abc/def/ghi.js');
isGlob('foo.js');
isGlob('abc/@.js');
isGlob('abc/+.js');
isGlob('abc/?.js');
isGlob();
isGlob(null);
//=> false

Arrays are also false (If you want to check if an array has a glob pattern, use has-glob):

isGlob(['**/*.js']);
isGlob(['foo.js']);
//=> false

Option strict

When options.strict === false the behavior is less strict in determining if a pattern is a glob. Meaning that some patterns that would return false may return true. This is done so that matching libraries like micromatch have a chance at determining if the pattern is a glob or not.

True

Patterns that have glob characters or regex patterns will return true:

isGlob('!foo.js', {strict: false});
isGlob('*.js', {strict: false});
isGlob('**/abc.js', {strict: false});
isGlob('abc/*.js', {strict: false});
isGlob('abc/(aaa|bbb).js', {strict: false});
isGlob('abc/[a-z].js', {strict: false});
isGlob('abc/{a,b}.js', {strict: false});
//=> true

Extglobs

isGlob('abc/@(a).js', {strict: false});
isGlob('abc/!(a).js', {strict: false});
isGlob('abc/+(a).js', {strict: false});
isGlob('abc/*(a).js', {strict: false});
isGlob('abc/?(a).js', {strict: false});
//=> true

False

Escaped globs or extglobs return false:

isGlob('\\!foo.js', {strict: false});
isGlob('\\*.js', {strict: false});
isGlob('\\*\\*/abc.js', {strict: false});
isGlob('abc/\\*.js', {strict: false});
isGlob('abc/\\(aaa|bbb).js', {strict: false});
isGlob('abc/\\[a-z].js', {strict: false});
isGlob('abc/\\{a,b}.js', {strict: false});
//=> false
