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.
Please consider following this project's author, Jon Schlinkert, and consider starring the project to show your :heart: and support.
Install with npm:
$ npm install --save is-glob

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