	 # creating Path::Tiny objects

	 $dir =	path("/tmp");
	 $foo =	path("foo.txt");

	 $subdir = $dir->child("foo");
	 $bar =	$subdir->child("bar.txt");

       This module provides a small, fast utility for working with file	paths.
       It is friendlier	to use than File::Spec and provides easy access	to
       functions from several other core file handling modules.	 It aims to be
       smaller and faster than many alternatives on CPAN, while	helping	people
       do many common things in	consistent and less error-prone	ways.

       Path::Tiny does not try to work for anything except Unix-like and Win32
       platforms.  Even	then, it might break if	you try	something particularly
       obscure or tortuous.  (Quick!  What does	this mean:
       "///../../..//./././a//b/.././c/././"?  And how does it differ on

       All paths are forced to have Unix-style forward slashes.	 Stringifying
       the object gives	you back the path (after some clean up).

       File input/output methods "flock" handles before	reading	or writing, as
       appropriate (if supported by the	platform and/or	filesystem).

       The *_utf8 methods ("slurp_utf8", "lines_utf8", etc.) operate in	raw
       mode.  On Windows, that means they will not have	CRLF translation from
       the ":crlf" IO layer.  Installing Unicode::UTF8 0.58 or later will
       speed up	*_utf8 situations in many cases	and is highly recommended.
       Alternatively, installing PerlIO::utf8_strict 0.003 or later will be
       used in place of	the default ":encoding(UTF-8)".

       This module depends heavily on PerlIO layers for	correct	operation and
       thus requires Perl 5.008001 or later.

	   $path = path("foo/bar");
	   $path = path("/tmp",	"file.txt"); # list
	   $path = path(".");		     # cwd
	   $path = path("~user/file.txt");   # tilde processing

       Constructs a "Path::Tiny" object.  It doesn't matter if you give	a file
       or directory path.  It's	still up to you	to call	directory-like methods
       only on directories and file-like methods only on files.	 This function
       is exported automatically by default.

       The first argument must be defined and have non-zero length or an
       exception will be thrown.  This prevents	subtle,	dangerous errors with
       code like "path(	maybe_undef() )->remove_tree".

       If the first component of the path is a tilde ('~') then	the component
       will be replaced	with the output	of "glob('~')".	 If the	first
       component of the	path is	a tilde	followed by a user name	then the
       component will be replaced with output of "glob('~username')".
       Behaviour for non-existent users	depends	on the output of "glob"	on the

       On Windows, if the path consists	of a drive identifier without a	path
       component ("C:" or "D:"), it will be expanded to	the absolute path of
       the current directory on	that volume using "Cwd::getdcwd()".

       If called with a	single "Path::Tiny" argument, the original is returned
       unless the original is holding a	temporary file or directory reference
       in which	case a stringified copy	is made.

	   $path = path("foo/bar");
	   $temp = Path::Tiny->tempfile;

	   $p2 = path($path); #	like $p2 = $path
	   $t2 = path($temp); #	like $t2 = path( "$temp" )

       This optimizes copies without proliferating references unexpectedly if
       a copy is made by code outside your control.

       Current API available since 0.017.

	   $path = Path::Tiny->new("foo/bar");

       This is just like "path", but with method call overhead.	 (Why would
       you do that?)

       Current API available since 0.001.

	   $path = Path::Tiny->cwd; # path( Cwd::getcwd	)
	   $path = cwd;	# optional export

       Gives you the absolute path to the current directory as a "Path::Tiny"
       object.	This is	slightly faster	than "path(".")->absolute".

       "cwd" may be exported on	request	and used as a function instead of as a

       Current API available since 0.018.

	   $path = Path::Tiny->rootdir;	# /
	   $path = rootdir;		# optional export

       Gives you "File::Spec->rootdir" as a "Path::Tiny" object	if you're too
       picky for "path("/")".

       "rootdir" may be	exported on request and	used as	a function instead of
       as a method.

       Current API available since 0.018.

   tempfile, tempdir
	   $temp = Path::Tiny->tempfile( @options );
	   $temp = Path::Tiny->tempdir(	@options );
	   $temp = tempfile( @options ); # optional export
	   $temp = tempdir( @options );	 # optional export

       "tempfile" passes the options to	"File::Temp->new" and returns a
       "Path::Tiny" object with	the file name.	The "TMPDIR" option is enabled
       by default.

       The resulting "File::Temp" object is cached. When the "Path::Tiny"
       object is destroyed, the	"File::Temp" object will be as well.

       "File::Temp" annoyingly requires	you to specify a custom	template in
       slightly	different ways depending on which function or method you call,
       but "Path::Tiny"	lets you ignore	that and can take either a leading
       template	or a "TEMPLATE"	option and does	the right thing.

	   $temp = Path::Tiny->tempfile( "customXXXXXXXX" );		 # ok
	   $temp = Path::Tiny->tempfile( TEMPLATE => "customXXXXXXXX" ); # ok

       The tempfile path object	will be	normalized to have an absolute path,
       even if created in a relative directory using "DIR".  If	you want it to
       have the	"realpath" instead, pass a leading options hash	like this:

	   $real_temp =	tempfile({realpath => 1}, @options);

       "tempdir" is just like "tempfile", except it calls "File::Temp->newdir"

       Both "tempfile" and "tempdir" may be exported on	request	and used as
       functions instead of as methods.

       Note: for tempfiles, the	filehandles from File::Temp are	closed and not
       reused.	This is	not as secure as using File::Temp handles directly,
       but is less prone to deadlocks or access	problems on some platforms.
       Think of	what "Path::Tiny" gives	you to be just a temporary file	name
       that gets cleaned up.

       Note 2: if you don't want these cleaned up automatically	when the
       object is destroyed, File::Temp requires	different options for
       directories and files.  Use "CLEANUP => 0" for directories and "UNLINK
       => 0" for files.

       Note 3: Don't lose the temporary	object by chaining a method call
       instead of storing it:

	   my $lost = tempdir()->child("foo"); # tempdir cleaned up right away

       Note 4: The cached object may be	accessed with the "cached_temp"
       method.	Keeping	a reference to,	or modifying the cached	object may
       break the behavior documented above and is not supported.  Use at your
       own risk.

       Current API available since 0.097.

	   $abs	= path("foo/bar")->absolute;
	   $abs	= path("foo/bar")->absolute("/tmp");

       Returns a new "Path::Tiny" object with an absolute path (or itself if
       already absolute).  If no argument is given, the	current	directory is
       used as the absolute base path.	If an argument is given, it will be
       converted to an absolute	path (if it is not already) and	used as	the
       absolute	base path.

       This will not resolve upward directories	("foo/../bar") unless
       "canonpath" in File::Spec would normally	do so on your platform.	 If
       you need	them resolved, you must	call the more expensive	"realpath"
       method instead.

       On Windows, an absolute path without a volume component will have it
       added based on the current drive.

       Current API available since 0.101.

   append, append_raw, append_utf8
	   path("foo.txt")->append({binmode => ":raw"},	@data);

       Appends data to a file.	The file is locked with	"flock"	prior to
       writing and closed afterwards.  An optional hash	reference may be used
       to pass options.	 Valid options are:

       o   "binmode": passed to	"binmode()" on the handle used for writing.

       o   "truncate": truncates the file after	locking	and before appending

       The "truncate" option is	a way to replace the contents of a file	in
       place, unlike "spew" which writes to a temporary	file and then replaces
       the original (if	it exists).

       "append_raw" is like "append" with a "binmode" of ":unix" for fast,
       unbuffered, raw write.

       "append_utf8" is	like "append" with a "binmode" of
       ":unix:encoding(UTF-8)" (or PerlIO::utf8_strict).  If Unicode::UTF8
       0.58+ is	installed, a raw append	will be	done instead on	the data
       encoded with "Unicode::UTF8".

       Current API available since 0.060.

	   $path = path("foo.txt")->assert( sub	{ $_->exists } );

       Returns the invocant after asserting that a code	reference argument
       returns true.  When the assertion code reference	runs, it will have the
       invocant	object in the $_ variable.  If it returns false, an exception
       will be thrown.	The assertion code reference may also throw its	own

       If no assertion is provided, the	invocant is returned without error.

       Current API available since 0.062.

	   $name = path("foo/bar.txt")->basename;	 # bar.txt
	   $name = path("foo.txt")->basename('.txt');	 # foo
	   $name = path("foo.txt")->basename(qr/.txt/);	 # foo
	   $name = path("foo.txt")->basename(@suffixes);

       Returns the file	portion	or last	directory portion of a path.

       Given a list of suffixes	as strings or regular expressions, any that
       match at	the end	of the file portion or last directory portion will be
       removed before the result is returned.

       Current API available since 0.054.

	   $canonical =	path("foo/bar")->canonpath; # foo\bar on Windows

       Returns a string	with the canonical format of the path name for the
       platform.  In particular, this means directory separators will be "\"
       on Windows.

       Current API available since 0.001.

       Returns the cached "File::Temp" or "File::Temp::Dir" object if the
       "Path::Tiny" object was created with "/tempfile"	or "/tempdir".	If
       there is	no such	object,	this method throws.

       WARNING:	Keeping	a reference to,	or modifying the cached	object may
       break the behavior documented for temporary files and directories
       created with "Path::Tiny" and is	not supported.	Use at your own	risk.

       Current API available since 0.101.

	   $file = path("/tmp")->child("foo.txt"); # "/tmp/foo.txt"
	   $file = path("/tmp")->child(@parts);

       Returns a new "Path::Tiny" object relative to the original.  Works like
       "catfile" or "catdir" from File::Spec, but without caring about file or

       WARNING:	because	the argument could contain ".."	or refer to symlinks,
       there is	no guarantee that the new path refers to an actual descendent
       of the original.	 If this is important to you, transform	parent and
       child with "realpath" and check them with "subsumes".

       Current API available since 0.001.

	   @paths = path("/tmp")->children;
	   @paths = path("/tmp")->children( qr/\.txt\z/	);

       Returns a list of "Path::Tiny" objects for all files and	directories
       within a	directory.  Excludes "." and ".." automatically.

       If an optional "qr//" argument is provided, it only returns objects for
       child names that	match the given	regular	expression.  Only the base
       name is used for	matching:

	   @paths = path("/tmp")->children( qr/^foo/ );
	   # matches children like the glob foo*

       Current API available since 0.028.


       Sets file or directory permissions.  The	argument can be	a numeric
       mode, a octal string beginning with a "0" or a limited subset of	the
       symbolic	mode use by /bin/chmod.

       The symbolic mode must be a comma-delimited list	of mode	clauses.
       Clauses must match "qr/\A([augo]+)([=+-])([rwx]+)\z/", which defines
       "who", "op" and "perms" parameters for each clause.  Unlike /bin/chmod,
       all three parameters are	required for each clause, multiple ops are not
       allowed and permissions "stugoX"	are not	supported.  (See File::chmod
       for more	complex	needs.)

       Current API available since 0.053.


       Copies the current path to the given destination	using File::Copy's
       "copy" function.	Upon success, returns the "Path::Tiny" object for the
       newly copied file.

       Current API available since 0.070.

	   $obj	= path("/tmp/foo.txt")->digest;	       # SHA-256
	   $obj	= path("/tmp/foo.txt")->digest("MD5"); # user-selected
	   $obj	= path("/tmp/foo.txt")->digest(	{ chunk_size =>	1e6 }, "MD5" );

       Returns a hexadecimal digest for	a file.	 An optional hash reference of
       options may be given.  The only option is "chunk_size".	If
       "chunk_size" is given, that many	bytes will be read at a	time.  If not
       provided, the entire file will be slurped into memory to	compute	the

       Any subsequent arguments	are passed to the constructor for Digest to
       select an algorithm.  If	no arguments are given,	the default is

       Current API available since 0.056.

   dirname (deprecated)
	   $name = path("/tmp/foo.txt")->dirname; # "/tmp/"

       Returns the directory portion you would get from	calling
       "File::Spec->splitpath( $path->stringify	)" or "." for a	path without a
       parent directory	portion.  Because File::Spec is	inconsistent, the
       result might or might not have a	trailing slash.	 Because of this, this
       method is deprecated.

       A better, more consistently approach is likely
       "$path->parent->stringify", which will not have a trailing slash	except
       for a root directory.

       Deprecated in 0.056.

   edit, edit_raw, edit_utf8
	   path("foo.txt")->edit( \&callback, $options );
	   path("foo.txt")->edit_utf8( \&callback );
	   path("foo.txt")->edit_raw( \&callback );

       These are convenience methods that allow	"editing" a file using a
       single callback argument. They slurp the	file using "slurp", place the
       contents	inside a localized $_ variable,	call the callback function
       (without	arguments), and	then write $_ (presumably mutated) back	to the
       file with "spew".

       An optional hash	reference may be used to pass options.	The only
       option is "binmode", which is passed to "slurp" and "spew".

       "edit_utf8" and "edit_raw" act like their respective "slurp_*" and
       "spew_*"	methods.

       Current API available since 0.077.

   edit_lines, edit_lines_utf8,	edit_lines_raw
	   path("foo.txt")->edit_lines(	\&callback, $options );
	   path("foo.txt")->edit_lines_utf8( \&callback	);
	   path("foo.txt")->edit_lines_raw( \&callback );

       These are convenience methods that allow	"editing" a file's lines using
       a single	callback argument.  They iterate over the file:	for each line,
       the line	is put into a localized	$_ variable, the callback function is
       executed	(without arguments) and	then $_	is written to a	temporary
       file.  When iteration is	finished, the temporary	file is	atomically
       renamed over the	original.

       An optional hash	reference may be used to pass options.	The only
       option is "binmode", which is passed to the method that open handles
       for reading and writing.

       "edit_lines_utf8" and "edit_lines_raw" act like their respective
       "slurp_*" and "spew_*" methods.

       Current API available since 0.077.

   exists, is_file, is_dir
	   if (	path("/tmp")->exists ) { ... }	   # -e
	   if (	path("/tmp")->is_dir ) { ... }	   # -d
	   if (	path("/tmp")->is_file )	{ ... }	   # -e	&& ! -d

       Implements file test operations,	this means the file or directory
       actually	has to exist on	the filesystem.	 Until then, it's just a path.

       Note: "is_file" is not "-f" because "-f"	is not the opposite of "-d".
       "-f" means "plain file",	excluding symlinks, devices, etc. that often
       can be read just	like files.

       Use "-f"	instead	if you really mean to check for	a plain	file.

       Current API available since 0.053.

	   $fh = path("/tmp/foo.txt")->filehandle($mode, $binmode);
	   $fh = path("/tmp/foo.txt")->filehandle({ locked => 1	}, $mode, $binmode);
	   $fh = path("/tmp/foo.txt")->filehandle({ exclusive => 1  }, $mode, $binmode);

       Returns an open file handle.  The $mode argument	must be	a Perl-style
       read/write mode string ("<" ,">", ">>", etc.).  If a $binmode is	given,
       it is set during	the "open" call.

       An optional hash	reference may be used to pass options.

       The "locked" option governs file	locking; if true, handles opened for
       writing,	appending or read-write	are locked with	"LOCK_EX"; otherwise,
       they are	locked with "LOCK_SH".	When using "locked", ">" or "+>" modes
       will delay truncation until after the lock is acquired.

       The "exclusive" option causes the open()	call to	fail if	the file
       already exists.	This corresponds to the	O_EXCL flag to sysopen /
       open(2).	 "exclusive" implies "locked" and will set it for you if you
       forget it.

       See "openr", "openw", "openrw", and "opena" for sugar.

   is_absolute,	is_relative
	   if (	path("/tmp")->is_absolute ) { ... }
	   if (	path("/tmp")->is_relative ) { ... }

       Booleans	for whether the	path appears absolute or relative.

       Current API available since 0.001.

	   while ( ! $path->is_rootdir ) {
	       $path = $path->parent;

       Boolean for whether the path is the root	directory of the volume.  I.e.
       the "dirname" is	"q[/]" and the "basename" is "q[]".

       This works even on "MSWin32" with drives	and UNC	volumes:

	   path("C:/")->is_rootdir;		# true
	   path("//server/share/")->is_rootdir;	#true

       Current API available since 0.038.

	   $iter = path("/tmp")->iterator( \%options );

       Returns a code reference	that walks a directory lazily.	Each
       invocation returns a "Path::Tiny" object	or undef when the iterator is

	   $iter = path("/tmp")->iterator;
	   while ( $path = $iter->() ) {

       The current and parent directory	entries	("." and "..") will not	be

       If the "recurse"	option is true,	the iterator will walk the directory
       recursively, breadth-first.  If the "follow_symlinks" option is also
       true, directory links will be followed recursively.  There is no
       protection against loops	when following links. If a directory is	not
       readable, it will not be	followed.

       The default is the same as:

	   $iter = path("/tmp")->iterator( {
	       recurse	       => 0,
	       follow_symlinks => 0,
	   } );

       see Path::Iterator::Rule.

   lines, lines_raw, lines_utf8
	   @contents = path("/tmp/foo.txt")->lines;
	   @contents = path("/tmp/foo.txt")->lines(\%options);
	   @contents = path("/tmp/foo.txt")->lines_raw;
	   @contents = path("/tmp/foo.txt")->lines_utf8;

	   @contents = path("/tmp/foo.txt")->lines( { chomp => 1, count	=> 4 } );

       Returns a list of lines from a file.  Optionally	takes a	hash-reference
       of options.  Valid options are "binmode", "count" and "chomp".

       If "binmode" is provided, it will be set	on the handle prior to

       If a positive "count" is	provided, that many lines will be returned
       from the	start of the file.  If a negative "count" is provided, the
       entire file will	be read, but only "abs(count)" will be kept and
       returned.  If "abs(count)" exceeds the number of	lines in the file, all
       lines will be returned.

       If "chomp" is set, any end-of-line character sequences ("CR", "CRLF",
       or "LF")	will be	removed	from the lines returned.

       Because the return is a list, "lines" in	scalar context will return the
       number of lines (and throw away the data).

	   $number_of_lines = path("/tmp/foo.txt")->lines;

       "lines_raw" is like "lines" with	a "binmode" of ":raw".	We use ":raw"
       instead of ":unix" so PerlIO buffering can manage reading by line.

       "lines_utf8" is like "lines" with a "binmode" of	":raw:encoding(UTF-8)"
       (or PerlIO::utf8_strict).  If Unicode::UTF8 0.58+ is installed, a raw
       UTF-8 slurp will	be done	and then the lines will	be split.  This	is
       actually	faster than relying on ":encoding(UTF-8)", though a bit	memory
       intensive.  If memory use is a concern, consider	"openr_utf8" and
       iterating directly on the handle.

       Current API available since 0.065.

	   path("foo/bar/baz")->mkpath(	\%options );

       Like calling "make_path"	from File::Path.  An optional hash reference
       is passed through to "make_path".  Errors will be trapped and an
       exception thrown.  Returns the list of directories created or an	empty
       list if the directories already exist, just like	"make_path".

       Move the	current	path to	the given destination path using Perl's	built-
       in rename function. Returns the result of the "rename" function (except
       it throws an exception if it fails).

   openr, openw, openrw, opena
	   $fh = path("foo.txt")->openr($binmode);  # read

	   $fh = path("foo.txt")->openrw_raw;
	   $fh = path("foo.txt")->openrw_utf8;

       Returns a file handle opened in the specified mode.  The	"openr"	style
       methods take a single "binmode" argument.  All of the "open*" methods
       have "open*_raw"	and "open*_utf8" equivalents that use ":raw" and
       ":raw:encoding(UTF-8)", respectively.

       An optional hash	reference may be used to pass options.	The only
       option is "locked".  If true, handles opened for	writing, appending or
       read-write are locked with "LOCK_EX"; otherwise,	they are locked	for

	   $fh = path("foo.txt")->openrw_utf8( { locked	=> 1 } );

       See "filehandle"	for more on locking.

	   $parent = path("foo/bar/baz")->parent; # foo/bar
	   $parent = path("foo/wibble.txt")->parent; # foo

	   $parent = path("foo/bar/baz")->parent(2); # foo

       Returns a "Path::Tiny" object corresponding to the parent directory of
       the original directory or file. An optional positive integer argument
       is the number of	parent directories upwards to return.  "parent"	by
       itself is equivalent to parent(1).

       Current API available since 0.014.

	   $real = path("/baz/foo/../bar")->realpath;
	   $real = path("foo/../bar")->realpath;

       Returns a new "Path::Tiny" object with all symbolic links and upward
       directory parts resolved	using Cwd's "realpath".	 Compared to
       "absolute", this	is more	expensive as it	must actually consult the

       If the parent path can't	be resolved (e.g. if it	includes directories
       that don't exist), an exception will be thrown:

	   $real = path("doesnt_exist/foo")->realpath; # dies

       However,	if the parent path exists and only the last component (e.g.
       filename) doesn't exist,	the realpath will be the realpath of the
       parent plus the non-existent last component:

	   $real = path("./aasdlfasdlf")->realpath; # works

       The underlying Cwd module usually worked	this way on Unix, but died on
       Windows (and some Unixes) if the	full path didn't exist.	 As of version
       0.064, it's safe	to use anywhere.

       Current API available since 0.001.

	   $rel	= path("/tmp/foo/bar")->relative("/tmp"); # foo/bar

       Returns a "Path::Tiny" object with a path relative to a new base	path
       given as	an argument.  If no argument is	given, the current directory
       will be used as the new base path.

       If either path is already relative, it will be made absolute based on
       the current directly before determining the new relative	path.

       The algorithm is	roughly	as follows:

       o   If the original and new base	path are on different volumes, an
	   exception will be thrown.

       o   If the original and new base	are identical, the relative path is

       o   If the new base subsumes the	original, the relative path is the
	   original path with the new base chopped off the front

       o   If the new base does	not subsume the	original, a common prefix path
	   is determined (possibly the root directory) and the relative	path
	   will	consist	of updirs ("..") to reach the common prefix, followed
	   by the original path	less the common	prefix.

       Unlike "File::Spec::abs2rel", in	the last case above, the calculation
       based on	a common prefix	takes into account symlinks that could affect
       the updir process.  Given an original path "/A/B" and a new base
       "/A/C", (where "A", "B" and "C" could each have multiple	path

       o   Symlinks in "A" don't change	the result unless the last component
	   of A	is a symlink and the first component of	"C" is an updir.

       o   Symlinks in "B" don't change	the result and will exist in the
	   result as given.

       o   Symlinks and	updirs in "C" must be resolved to actual paths,	taking
	   into	account	the possibility	that not all path components might
	   exist on the	filesystem.

       symlinks) available since 0.079.


       This is just like "unlink", except for its error	handling: if the path
       does not	exist, it returns false; if deleting the file fails, it	throws
       an exception.

       Current API available since 0.012.

	   # directory
	   path("foo/bar/baz")->remove_tree( \%options );
	   path("foo/bar/baz")->remove_tree( { safe => 0 } ); #	force remove

       Like calling "remove_tree" from File::Path, but defaults	to "safe"
       mode.  An optional hash reference is passed through to "remove_tree".
       Errors will be trapped and an exception thrown.	Returns	the number of
       directories deleted, just like "remove_tree".

       If you want to remove a directory only if it is empty, use the built-in
       "rmdir" function	instead.

	   rmdir path("foo/bar/baz/");

       Current API available since 0.013.

	   $foo	= path("/tmp/foo.txt");
	   $sib	= $foo->sibling("bar.txt");	   # /tmp/bar.txt
	   $sib	= $foo->sibling("baz", "bam.txt"); # /tmp/baz/bam.txt

       Returns a new "Path::Tiny" object relative to the parent	of the
       original.  This is slightly more	efficient than

       Current API available since 0.058.

   slurp, slurp_raw, slurp_utf8
	   $data = path("foo.txt")->slurp;
	   $data = path("foo.txt")->slurp( {binmode => ":raw"} );
	   $data = path("foo.txt")->slurp_raw;
	   $data = path("foo.txt")->slurp_utf8;

       Reads file contents into	a scalar.  Takes an optional hash reference
       which may be used to pass options.  The only available option is
       "binmode", which	is passed to "binmode()" on the	handle used for

       "slurp_raw" is like "slurp" with	a "binmode" of ":unix" for a fast,
       unbuffered, raw read.

       "slurp_utf8" is like "slurp" with a "binmode" of
       ":unix:encoding(UTF-8)" (or PerlIO::utf8_strict).  If Unicode::UTF8
       0.58+ is	installed, a raw slurp will be done instead and	the result
       decoded with "Unicode::UTF8".  This is just as strict and is roughly an
       order of	magnitude faster than using ":encoding(UTF-8)".

       Note: "slurp" and friends lock the filehandle before slurping.  If you
       plan to slurp from a file created with File::Temp, be sure to close
       other handles or	open without locking to	avoid a	deadlock:

	   my $tempfile	= File::Temp->new(EXLOCK => 0);
	   my $guts = path($tempfile)->slurp;

       Current API available since 0.004.

   spew, spew_raw, spew_utf8
	   path("foo.txt")->spew({binmode => ":raw"}, @data);

       Writes data to a	file atomically.  The file is written to a temporary
       file in the same	directory, then	renamed	over the original.  An
       optional	hash reference may be used to pass options.  The only option
       is "binmode", which is passed to	"binmode()" on the handle used for

       "spew_raw" is like "spew" with a	"binmode" of ":unix" for a fast,
       unbuffered, raw write.

       "spew_utf8" is like "spew" with a "binmode" of ":unix:encoding(UTF-8)"
       (or PerlIO::utf8_strict).  If Unicode::UTF8 0.58+ is installed, a raw
       spew will be done instead on the	data encoded with "Unicode::UTF8".

       NOTE: because the file is written to a temporary	file and then renamed,
       the new file will wind up with permissions based	on your	current	umask.
       This is a feature to protect you	from a race condition that would
       otherwise give different	permissions than you might expect.  If you
       really want to keep the original	mode flags, use	"append" with the
       "truncate" option.

       Current API available since 0.011.

   stat, lstat
	   $stat = path("foo.txt")->stat;
	   $stat = path("/some/symlink")->lstat;

       Like calling "stat" or "lstat" from File::stat.

       Current API available since 0.001.

	   $path = path("foo.txt");
	   say $path->stringify; # same	as "$path"

       Returns a string	representation of the path.  Unlike "canonpath", this
       method returns the path standardized with Unix-style "/"	directory

       Current API available since 0.001.

	   path("foo/bar")->subsumes("foo/bar/baz"); # true
	   path("/foo/bar")->subsumes("/foo/baz");   # false

       Returns true if the first path is a prefix of the second	path at	a
       directory boundary.

       This does not resolve parent directory entries ("..") or	symlinks:

	   path("foo/bar")->subsumes("foo/bar/../baz");	# true

       If such things are important to you, ensure that	both paths are
       resolved	to the filesystem with "realpath":

	   my $p1 = path("foo/bar")->realpath;
	   my $p2 = path("foo/bar/../baz")->realpath;
	   if (	$p1->subsumes($p2) ) { ... }

       Current API available since 0.048.


       Like the	Unix "touch" utility.  Creates the file	if it doesn't exist,
       or else changes the modification	and access times to the	current	time.
       If the first argument is	the epoch seconds then it will be used.

       Returns the path	object so it can be easily chained with	other methods:

	   # won't die if foo.txt doesn't exist
	   $content = path("foo.txt")->touch->slurp;

       Current API available since 0.015.


       Combines	"mkpath" and "touch".  Creates the parent directory if it
       doesn't exist, before touching the file.	 Returns the path object like
       "touch" does.

       Current API available since 0.022.

	   path("/tmp")->visit(	\&callback, \%options );

       Executes	a callback for each child of a directory.  It returns a	hash
       reference with any state	accumulated during iteration.

       The options are the same	as for "iterator" (which it uses internally):
       "recurse" and "follow_symlinks".	 Both default to false.

       The callback function will receive a "Path::Tiny" object	as the first
       argument	and a hash reference to	accumulate state as the	second
       argument.  For example:

	   # collect files sizes
	   my $sizes = path("/tmp")->visit(
	       sub {
		   my ($path, $state) =	@_;
		   return if $path->is_dir;
		   $state->{$path} = -s	$path;
	       { recurse => 1 }

       For convenience,	the "Path::Tiny" object	will also be locally aliased
       as the $_ global	variable:

	   # print paths matching /foo/
	   path("/tmp")->visit(	sub { say if /foo/ }, {	recurse	=> 1} );

       If the callback returns a reference to a	false scalar value, iteration
       will terminate.	This is	not the	same as	"pruning" a directory search;
       this just stops all iteration and returns the state hash	reference.

	   # find up to	10 files larger	than 100K
	   my $files = path("/tmp")->visit(
	       sub {
		   my ($path, $state) =	@_;
		   $state->{$path}++ if	-s $path > 102400
		   return \0 if	keys %$state ==	10;
	       { recurse => 1 }

       If you want more	flexible iteration, use	a module like

       Current API available since 0.062.

	   $vol	= path("/tmp/foo.txt")->volume;	  # ""
	   $vol	= path("C:/tmp/foo.txt")->volume; # "C:"

       Returns the volume portion of the path.	This is	equivalent to what
       File::Spec would	give from "splitpath" and thus usually is the empty
       string on Unix-like operating systems or	the drive letter for an
       absolute	path on	"MSWin32".

       Current API available since 0.001.

       Simple usage errors will	generally croak.  Failures of underlying Perl
       functions will be thrown	as exceptions in the class

       A "Path::Tiny::Error" object will be a hash reference with the
       following fields:

       o   "op"	a a description	of the operation, usually function call	and
	   any extra info

       o   "file" a the	file or	directory relating to the error

       o   "err" a hold	$! at the time the error was thrown

       o   "msg" a a string combining the above	data and a Carp-like short
	   stack trace

       Exception objects will stringify	as the "msg" field.

       If the environment variable "PERL_PATH_TINY_NO_FLOCK" is	set to a true
       value then flock	will NOT be used when accessing	files (this is not

   Subclassing not supported
       For speed, this class is	implemented as an array	based object and uses
       many direct function calls internally.  You must	not subclass it	and
       expect things to	work properly.

   File	locking
       If flock	is not supported on a platform,	it will	not be used, even if
       locking is requested.

       In situations where a platform normally would support locking, but the
       flock fails due to a filesystem limitation, Path::Tiny has some
       heuristics to detect this and will warn once and	continue in an unsafe
       mode.  If you want this failure to be fatal, you	can fatalize the
       'flock' warnings	category:

	   use warnings	FATAL => 'flock';

       See additional caveats below.

       NFS and BSD

       On BSD, Perl's flock implementation may not work	to lock	files on an
       NFS filesystem.	If detected, this situation will warn once, as
       described above.


       The Lustre filesystem does not support flock.  If detected, this
       situation will warn once, as described above.

       AIX and locking

       AIX requires a write handle for locking.	 Therefore, calls that
       normally	open a read handle and take a shared lock instead will open a
       read-write handle and take an exclusive lock.  If the user does not
       have write permission, no lock will be used.

   utf8	vs UTF-8
       All the *_utf8 methods by default use ":encoding(UTF-8)"	-- either as
       ":unix:encoding(UTF-8)" (unbuffered) or ":raw:encoding(UTF-8)"
       (buffered) -- which is strict against the Unicode spec and disallows
       illegal Unicode codepoints or UTF-8 sequences.

       Unfortunately, ":encoding(UTF-8)" is very, very slow.  If you install
       Unicode::UTF8 0.58 or later, that module	will be	used by	some *_utf8
       methods to encode or decode data	after a	raw, binary input/output
       operation, which	is much	faster.	 Alternatively,	if you install
       PerlIO::utf8_strict, that will be used instead of ":encoding(UTF-8)"
       and is also very	fast.

       If you need the performance and can accept the security risk,
       "slurp({binmode => ":unix:utf8"})" will be faster than
       ":unix:encoding(UTF-8)" (but not	as fast	as "Unicode::UTF8").

       Note that the *_utf8 methods read in raw	mode.  There is	no CRLF
       translation on Windows.	If you must have CRLF translation, use the
       regular input/output methods with an appropriate	binmode:

	 $path->spew_utf8($data);			     # raw
	 $path->spew({binmode => ":encoding(UTF-8)"}, $data; # LF -> CRLF

   Default IO layers and the open pragma
       If you have Perl	5.10 or	later, file input/output methods ("slurp",
       "spew", etc.) and high-level handle opening methods ( "filehandle",
       "openr",	"openw", etc. )	respect	default	encodings set by the "-C"
       switch or lexical open settings of the caller.  For UTF-8, this is
       almost certainly	slower than using the dedicated	"_utf8"	methods	if you
       have Unicode::UTF8.

       A standard MooseX::Types	library	is available at
       MooseX::Types::Path::Tiny.  A Type::Tiny	equivalent is available	as

       These are other file/path utilities, which may offer a different
       feature set than	"Path::Tiny".

       o   File::chmod

       o   File::Fu

       o   IO::All

       o   Path::Class

       These iterators may be slightly faster than the recursive iterator in

       o   Path::Iterator::Rule

       o   File::Next

       There are probably comparable, non-Tiny tools.  Let me know if you want
       me to add a module to the list.
