Test if a value is an absolute path.

Package Exports

  • @stdlib/assert-is-absolute-path

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/assert-is-absolute-path) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

isAbsolutePath

NPM version Build Status Coverage Status dependencies

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

CLI

Installation

To use the module as a general utility, install the module globally

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

Usage

Usage: is-absolute-path [options] [<path>]

Options:

  -h,    --help                Print this message.
  -V,    --version             Print the package version.
         --platform name       Platform: 'win32' or 'posix'.
