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 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 toisAbsolutePath.win32(). On POSIX platforms, the function is equal toisAbsolutePath.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
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'.
--split sep Delimiter for stdin data. Default: '/\\r?\\n/'.
Notes
If the split separator is a regular expression, ensure that the
splitoption is either properly escaped or enclosed in quotes.# Not escaped... $ echo -n $'/foo/bar/baz\n./docs/repl.txt' | is-absolute-path --split /\r?\n/ # Escaped... $ echo -n $'/foo/bar/baz\n./docs/repl.txt' | is-absolute-path --split /\\r?\\n/The implementation ignores trailing delimiters.
Examples
$ is-absolute-path /foo/bar/baz --platform=posix
true
To use as a standard stream,
$ echo -n './docs/repl.txt' | is-absolute-path
false
By default, when used as a standard stream, the implementation assumes newline-delimited data. To specify an alternative delimiter, set the split option.
$ echo -n '/foo/bar/baz\t./docs/repl.txt' | is-absolute-path --platform=posix --split '\t'
true
false
