@stdlib/assert-is-absolute-path NPM

isAbsolutePath

Test if a value is an absolute path.

Installation

npm install @stdlib/assert-is-absolute-path

Usage

var isAbsolutePath = require( '@stdlib/assert-is-absolute-path' );

isAbsolutePath( value )

Tests if a value is an absolute path.

var IS_WINDOWS = require( '@stdlib/assert-is-windows' );

var bool;
if ( IS_WINDOWS ) {
    bool = isAbsolutePath( 'C:\\foo\\bar\\baz' );
    // returns true
} else {
    bool = isAbsolutePath( '/foo/bar/baz' );
    // returns true
}

isAbsolutePath.posix( value )

Tests if a value is a POSIX absolute path.

var bool = isAbsolutePath.posix( '/foo/bar/baz' );
// returns true

bool = isAbsolutePath.posix( 'foo/bar/baz' );
// returns false

isAbsolutePath.win32( value )

Tests if a value is a Windows absolute path.

var bool = isAbsolutePath.win32( 'C:\\foo\\bar\\baz' );
// returns true

bool = isAbsolutePath.win32( 'foo\\bar\\baz' );
// returns false

Notes

isAbsolutePath() is platform-specific. On Windows platforms, the function is equal to isAbsolutePath.win32(). On POSIX platforms, the function is equal to isAbsolutePath.posix().

Examples

var isAbsolutePath = require( '@stdlib/assert-is-absolute-path' );

var bool = isAbsolutePath.posix( '/foo/bar/baz' );
// returns true

bool = isAbsolutePath.posix( '/foo/..' );
// returns true

bool = isAbsolutePath.posix( 'foo/' );
// returns false

bool = isAbsolutePath.posix( 'foo' );
// returns false

bool = isAbsolutePath.posix( '.' );
// returns false

bool = isAbsolutePath.posix( '' );
// returns false

bool = isAbsolutePath.win32( 'C:\\foo\\bar\\baz' );
// returns true

bool = isAbsolutePath.win32( '//server' );
// returns true

bool = isAbsolutePath.win32( '\\\\server' );
// returns true

bool = isAbsolutePath.win32( 'C:/foo/bar/baz' );
// returns true

bool = isAbsolutePath.win32( '/foo/..' );
// returns true

bool = isAbsolutePath.win32( 'foo\\bar\\baz' );
// returns false

bool = isAbsolutePath.win32( 'foo/bar/baz' );
// returns false

bool = isAbsolutePath.win32( 'foo/..' );
// returns false

bool = isAbsolutePath.win32( '.' );
// returns false

bool = isAbsolutePath.win32( '' );
// returns false

Notice

This package is part of 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.
