<details> <summary> About stdlib... </summary> <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p> <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p> <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p> <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p> </details> # isRelativePath [![NPM version][npm-image]][npm-url] [![Build Status][test-image]][test-url] [![Coverage Status][coverage-image]][coverage-url]  > Test if a value is a relative path. <section class="intro"> </section>  <section class="installation"> ## Installation ```bash npm install @stdlib/assert-is-relative-path ``` </section> <section class="usage"> ## Usage ```javascript var isRelativePath = require( '@stdlib/assert-is-relative-path' ); ``` #### isRelativePath( value ) Tests if a `value` is a relative path. ```javascript var IS_WINDOWS = require( '@stdlib/assert-is-windows' ); var bool; if ( IS_WINDOWS ) { bool = isRelativePath( 'foo\\bar\\baz' ); // returns true bool = isRelativePath( 'C:\\foo\\..\\bar\\baz' ); // returns false } else { bool = isRelativePath( './foo/bar/baz' ); // returns true bool = isRelativePath( '/foo/../bar/baz' ); // returns false } ``` #### isRelativePath.posix( value ) Tests if a `value` is a POSIX relative path. ```javascript var bool = isRelativePath.posix( './foo/bar/baz' ); // returns true bool = isRelativePath.posix( '/foo/../bar/baz' ); // returns false ``` #### isRelativePath.win32( value ) Tests if a `value` is a Windows relative path. ```javascript var bool = isRelativePath.win32( 'foo\\bar\\baz' ); // returns true bool = isRelativePath.win32( 'C:\\foo\\..\\bar\\baz' ); // returns false ``` </section>  <section class="notes"> ## Notes - `isRelativePath()` is platform-specific. On Windows platforms, the function is equal to `isRelativePath.win32()`. On POSIX platforms, the function is equal to `isRelativePath.posix()`. </section>  <section class="examples"> ## Examples  ```javascript var isRelativePath = require( '@stdlib/assert-is-relative-path' ); var bool = isRelativePath.posix( 'foo/' ); // returns true bool = isRelativePath.posix( 'foo' ); // returns true bool = isRelativePath.posix( '.' ); // returns true bool = isRelativePath.posix( '' ); // returns true bool = isRelativePath.posix( '/foo/bar/baz' ); // returns false bool = isRelativePath.posix( '/foo/..' ); // returns false bool = isRelativePath.win32( 'foo\\bar\\baz' ); // returns true bool = isRelativePath.win32( 'foo/bar/baz' ); // returns true bool = isRelativePath.win32( 'foo/..' ); // returns true bool = isRelativePath.win32( '.' ); // returns true bool = isRelativePath.win32( '' ); // returns true bool = isRelativePath.win32( 'C:\\foo\\bar\\baz' ); // returns false bool = isRelativePath.win32( '//server' ); // returns false bool = isRelativePath.win32( '\\\\server' ); // returns false bool = isRelativePath.win32( 'C:/foo/bar/baz' ); // returns false bool = isRelativePath.win32( '/foo/..' ); // returns false ``` </section>   <section class="related"> ## See Also - <span class="package-name">[`@stdlib/assert-is-relative-path-cli`][@stdlib/assert-is-relative-path-cli]</span><span class="delimiter">: </span><span class="description">CLI package for use as a command-line utility.</span> - <span class="package-name">[`@stdlib/assert-is-absolute-path`][@stdlib/assert/is-absolute-path]</span><span class="delimiter">: </span><span class="description">test if a value is an absolute path.</span> </section>   <section class="main-repo" > * * * ## Notice This package is part of [stdlib][stdlib], a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
