is-extglob

What is is-extglob?

The is-extglob npm package is used to check if a string has an extglob pattern. Extglob patterns are extensions to the basic glob patterns, allowing for more expressive matches. This package is particularly useful in applications that need to parse, interpret, or validate file paths and patterns for more complex matching criteria than simple wildcard matches.

What are is-extglob's main functionalities?

Check if a string is an extglob pattern

This feature allows you to check if a given string is an extglob pattern. The function returns true if the string is an extglob pattern, otherwise false. This is useful for validating or parsing strings that are expected to be in extglob format.

"const isExtglob = require('is-extglob');\nconsole.log(isExtglob('!(pattern)')); // true\nconsole.log(isExtglob('pattern')); // false"

Other packages similar to is-extglob

micromatch

Micromatch is a more comprehensive glob matching library that supports extglobs, braces, and other complex patterns. It is similar to is-extglob in that it can recognize extglob patterns, but it also provides a wide range of additional features for matching, filtering, and working with glob patterns. Compared to is-extglob, micromatch offers a broader set of functionalities for dealing with glob patterns.

extglob

Extglob is closely related to is-extglob, as it not only allows checking for extglob patterns but also provides functions to convert extglob strings into regex patterns. This package is more about utilizing extglob patterns rather than just identifying them. It complements is-extglob by offering a way to work with the patterns identified by is-extglob.

Install

Install with npm:

$ npm install --save is-extglob

Usage

var isExtglob = require('is-extglob');

True

isExtglob('?(abc)');
isExtglob('@(abc)');
isExtglob('!(abc)');
isExtglob('*(abc)');
isExtglob('+(abc)');

False

Escaped extglobs:

isExtglob('\\?(abc)');
isExtglob('\\@(abc)');
isExtglob('\\!(abc)');
isExtglob('\\*(abc)');
isExtglob('\\+(abc)');

Everything else...

isExtglob('foo.js');
isExtglob('!foo.js');
isExtglob('*.js');
isExtglob('**/abc.js');
isExtglob('abc/*.js');
isExtglob('abc/(aaa|bbb).js');
isExtglob('abc/[a-z].js');
isExtglob('abc/{a,b}.js');
isExtglob('abc/?.js');
isExtglob('abc.js');
isExtglob('abc/def/ghi.js');

History
