isAbsolutePath

Test if a value is an absolute path.

Usage

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

isAbsolutePath( value )

Tests if a value is an absolute path.

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

var bool;
if ( isWindows ) {
    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
