#pod $path = path("."); # cwd
#pod
#pod Constructs a C<Path::Tiny> object. It doesn't matter if you give a file or
#pod directory path. It's still up to you to call directory-like methods only on
#pod directories and file-like methods only on files. This function is exported
#pod automatically by default.
#pod
#pod The first argument must be defined and have non-zero length or an exception
#pod will be thrown. This prevents subtle, dangerous errors with code like
#pod C<< path( maybe_undef() )->remove_tree >>.
#pod
#pod B<DEPRECATED>: If and only if the B<first> character of the B<first> argument
#pod to C<path> is a tilde ('~'), then tilde replacement will be applied to the
#pod first path segment. A single tilde will be replaced with C<glob('~')> and a
#pod tilde followed by a username will be replaced with output of
#pod C<glob('~username')>. B<No other method does tilde expansion on its arguments>.
#pod See L</Tilde expansion (deprecated)> for more.
#pod
#pod On Windows, if the path consists of a drive identifier without a path component
#pod (C<C:> or C<D:>), it will be expanded to the absolute path of the current
#pod directory on that volume using C<Cwd::getdcwd()>.
#pod
#pod If called with a single C<Path::Tiny> argument, the original is returned unless
#pod the original is holding a temporary file or directory reference in which case a
#pod stringified copy is made.

#pod made by code outside your control.

#pod $temp = $dirpath->tempdir( @options );
#pod $temp = tempfile( @options ); # optional export
#pod $temp = tempdir( @options ); # optional export
#pod
#pod C<tempfile> passes the options to C<< File::Temp->new >> and returns a
#pod C<Path::Tiny> object with the file name. The C<TMPDIR> option will be enabled
#pod by default, but you can override that by passing C<< TMPDIR => 0 >> along with
#pod the options. (If you use an absolute C<TEMPLATE> option, you will want to
#pod disable C<TMPDIR>.)
#pod
#pod The resulting C<File::Temp> object is cached. When the C<Path::Tiny> object is
#pod destroyed, the C<File::Temp> object will be as well.
#pod
#pod C<File::Temp> annoyingly requires you to specify a custom template in slightly
#pod different ways depending on which function or method you call, but
#pod C<Path::Tiny> lets you ignore that and can take either a leading template or a
#pod C<TEMPLATE> option and does the right thing.
#pod
#pod $temp = Path::Tiny->tempfile( "customXXXXXXXX" ); # ok
#pod $temp = Path::Tiny->tempfile( TEMPLATE => "customXXXXXXXX" ); # ok
#pod
#pod The tempfile path object will be normalized to have an absolute path, even if
#pod created in a relative directory using C<DIR>. If you want it to have
#pod the C<realpath> instead, pass a leading options hash like this:
#pod
#pod $real_temp = tempfile({realpath => 1}, @options);
#pod
#pod C<tempdir> is just like C<tempfile>, except it calls
#pod C<< File::Temp->newdir >> instead.
#pod
#pod Both C<tempfile> and C<tempdir> may be exported on request and used as
#pod functions instead of as methods.
#pod
#pod The methods can be called on an instances representing a
#pod directory. In this case, the directory is used as the base to create the
#pod temporary file/directory, setting the C<DIR> option in File::Temp.
#pod
#pod my $target_dir = path('/to/destination');
#pod my $tempfile = $target_dir->tempfile('foobarXXXXXX');
#pod $tempfile->spew('A lot of data...'); # not atomic
#pod $tempfile->move($target_dir->child('foobar')); # hopefully atomic
#pod
#pod In this case, any value set for option C<DIR> is ignored.
#pod
#pod B<Note>: for tempfiles, the filehandles from File::Temp are closed and not
#pod reused. This is not as secure as using File::Temp handles directly, but is
#pod less prone to deadlocks or access problems on some platforms. Think of what
#pod C<Path::Tiny> gives you to be just a temporary file B<name> that gets cleaned
#pod up.
#pod
#pod B<Note 2>: if you don't want these cleaned up automatically when the object
#pod is destroyed, File::Temp requires different options for directories and
#pod files. Use C<< CLEANUP => 0 >> for directories and C<< UNLINK => 0 >> for
#pod files.
#pod
#pod B<Note 3>: Don't lose the temporary object by chaining a method call instead
#pod of storing it:
#pod
#pod my $lost = tempdir()->child("foo"); # tempdir cleaned up right away
#pod
#pod B<Note 4>: The cached object may be accessed with the L</cached_temp> method.
#pod Keeping a reference to, or modifying the cached object may break the
#pod behavior documented above and is not supported. Use at your own risk.

#pod =method relative
#pod
#pod $rel = path("/tmp/foo/bar")->relative("/tmp"); # foo/bar
#pod
#pod Returns a C<Path::Tiny> object with a path relative to a new base path
#pod given as an argument. If no argument is given, the current directory will
#pod be used as the new base path.
#pod
#pod If either path is already relative, it will be made absolute based on the
#pod current directly before determining the new relative path.
#pod
#pod The algorithm is roughly as follows:
#pod
#pod =for :list
#pod * If the original and new base path are on different volumes, an exception
#pod will be thrown.
#pod * If the original and new base are identical, the relative path is C<".">.
#pod * If the new base subsumes the original, the relative path is the original
#pod path with the new base chopped off the front
#pod * If the new base does not subsume the original, a common prefix path is
#pod determined (possibly the root directory) and the relative path will
#pod consist of updirs (C<"..">) to reach the common prefix, followed by the
#pod original path less the common prefix.
#pod
#pod Unlike C<File::Spec::abs2rel>, in the last case above, the calculation based
#pod on a common prefix takes into account symlinks that could affect the updir
#pod process. Given an original path "/A/B" and a new base "/A/C",
#pod (where "A", "B" and "C" could each have multiple path components):
#pod
#pod =for :list
#pod * Symlinks in "A" don't change the result unless the last component of A is
#pod a symlink and the first component of "C" is an updir.
#pod * Symlinks in "B" don't change the result and will exist in the result as
#pod given.
#pod * Symlinks and updirs in "C" must be resolved to actual paths, taking into
#pod account the possibility that not all path components might exist on the
#pod filesystem.

=head1 DESCRIPTION
This module provides a small, fast utility for working with file paths. It is
friendlier to use than L<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:
C<< ///../../..//./././a//b/.././c/././ >>? And how does it differ on Win32?)
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 C<flock> handles before reading or writing,
as appropriate (if supported by the platform and/or filesystem).
The C<*_utf8> methods (C<slurp_utf8>, C<lines_utf8>, etc.) operate in raw
mode. On Windows, that means they will not have CRLF translation from the
C<:crlf> IO layer. Installing L<Unicode::UTF8> 0.58 or later will speed up
C<*_utf8> situations in many cases and is highly recommended.
Alternatively, installing L<PerlIO::utf8_strict> 0.003 or later will be
used in place of the default C<:encoding(UTF-8)>.
This module depends heavily on PerlIO layers for correct operation and thus
requires Perl 5.008001 or later.
=head1 CONSTRUCTORS
=head2 path
$path = path("foo/bar");
$path = path("/tmp", "file.txt"); # list
$path = path("."); # cwd
Constructs a C<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
C<< path( maybe_undef() )->remove_tree >>.
B<DEPRECATED>: If and only if the B<first> character of the B<first> argument
to C<path> is a tilde ('~'), then tilde replacement will be applied to the
first path segment. A single tilde will be replaced with C<glob('~')> and a
tilde followed by a username will be replaced with output of
C<glob('~username')>. B<No other method does tilde expansion on its arguments>.
See L</Tilde expansion (deprecated)> for more.
On Windows, if the path consists of a drive identifier without a path component
(C<C:> or C<D:>), it will be expanded to the absolute path of the current
directory on that volume using C<Cwd::getdcwd()>.
If called with a single C<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.
=head2 new
$path = Path::Tiny->new("foo/bar");
This is just like C<path>, but with method call overhead. (Why would you
do that?)
Current API available since 0.001.
=head2 cwd
$path = Path::Tiny->cwd; # path( Cwd::getcwd )
$path = cwd; # optional export
Gives you the absolute path to the current directory as a C<Path::Tiny> object.
This is slightly faster than C<< path(".")->absolute >>.
C<cwd> may be exported on request and used as a function instead of as a
method.
Current API available since 0.018.
=head2 rootdir
$path = Path::Tiny->rootdir; # /
$path = rootdir; # optional export
Gives you C<< File::Spec->rootdir >> as a C<Path::Tiny> object if you're too
picky for C<path("/")>.
C<rootdir> may be exported on request and used as a function instead of as a
method.
Current API available since 0.018.
=head2 tempfile, tempdir
$temp = Path::Tiny->tempfile( @options );
$temp = Path::Tiny->tempdir( @options );
$temp = $dirpath->tempfile( @options );
$temp = $dirpath->tempdir( @options );
$temp = tempfile( @options ); # optional export
$temp = tempdir( @options ); # optional export
C<tempfile> passes the options to C<< File::Temp->new >> and returns a
C<Path::Tiny> object with the file name. The C<TMPDIR> option will be enabled
by default, but you can override that by passing C<< TMPDIR => 0 >> along with
the options. (If you use an absolute C<TEMPLATE> option, you will want to
disable C<TMPDIR>.)
The resulting C<File::Temp> object is cached. When the C<Path::Tiny> object is
destroyed, the C<File::Temp> object will be as well.
C<File::Temp> annoyingly requires you to specify a custom template in slightly
different ways depending on which function or method you call, but
C<Path::Tiny> lets you ignore that and can take either a leading template or a
C<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 C<DIR>. If you want it to have
the C<realpath> instead, pass a leading options hash like this:
$real_temp = tempfile({realpath => 1}, @options);
C<tempdir> is just like C<tempfile>, except it calls
C<< File::Temp->newdir >> instead.
Both C<tempfile> and C<tempdir> may be exported on request and used as
functions instead of as methods.
The methods can be called on an instances representing a
directory. In this case, the directory is used as the base to create the
temporary file/directory, setting the C<DIR> option in File::Temp.
my $target_dir = path('/to/destination');
my $tempfile = $target_dir->tempfile('foobarXXXXXX');
$tempfile->spew('A lot of data...'); # not atomic
$tempfile->move($target_dir->child('foobar')); # hopefully atomic
In this case, any value set for option C<DIR> is ignored.
B<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
C<Path::Tiny> gives you to be just a temporary file B<name> that gets cleaned
up.
B<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 C<< CLEANUP => 0 >> for directories and C<< UNLINK => 0 >> for
files.
B<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
B<Note 4>: The cached object may be accessed with the L</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.

=head1 METHODS
=head2 absolute
$abs = path("foo/bar")->absolute;
$abs = path("foo/bar")->absolute("/tmp");
Returns a new C<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 C<canonpath>
in L<File::Spec> would normally do so on your platform. If you need them
resolved, you must call the more expensive C<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.
=head2 append, append_raw, append_utf8
path("foo.txt")->append(@data);
path("foo.txt")->append(\@data);
path("foo.txt")->append({binmode => ":raw"}, @data);
path("foo.txt")->append_raw(@data);
path("foo.txt")->append_utf8(@data);
Appends data to a file. The file is locked with C<flock> prior to writing
and closed afterwards. An optional hash reference may be used to pass
options. Valid options are:
=over 4
=item *
C<binmode>: passed to C<binmode()> on the handle used for writing.
=item *
C<truncate>: truncates the file after locking and before appending
=back
The C<truncate> option is a way to replace the contents of a file
B<in place>, unlike L</spew> which writes to a temporary file and then
replaces the original (if it exists).
C<append_raw> is like C<append> with a C<binmode> of C<:unix> for a fast,
unbuffered, raw write.
C<append_utf8> is like C<append> with an unbuffered C<binmode>
C<:unix:encoding(UTF-8)> (or C<:unix:utf8_strict> with
L<PerlIO::utf8_strict>). If L<Unicode::UTF8> 0.58+ is installed, an
unbuffered, raw append will be done instead on the data encoded with
C<Unicode::UTF8>.
Current API available since 0.060.
=head2 assert
$path = path("foo.txt")->assert( sub { $_->exists } );
Returns the invocant after asserting that a code reference argument returns
true. When the assertion code reference runs, it will have the invocant
object in the C<$_> variable. If it returns false, an exception will be
thrown. The assertion code reference may also throw its own exception.
If no assertion is provided, the invocant is returned without error.
Current API available since 0.062.
=head2 basename
$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.
=head2 canonpath
$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 C<\> on Windows.
Current API available since 0.001.
=head2 cached_temp
Returns the cached C<File::Temp> or C<File::Temp::Dir> object if the
C<Path::Tiny> object was created with C</tempfile> or C</tempdir>.
If there is no such object, this method throws.
B<WARNING>: Keeping a reference to, or modifying the cached object may
break the behavior documented for temporary files and directories created
with C<Path::Tiny> and is not supported. Use at your own risk.
Current API available since 0.101.
=head2 child
$file = path("/tmp")->child("foo.txt"); # "/tmp/foo.txt"
$file = path("/tmp")->child(@parts);
Returns a new C<Path::Tiny> object relative to the original. Works
like C<catfile> or C<catdir> from File::Spec, but without caring about
file or directories.
B<WARNING>: because the argument could contain C<..> 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
L</realpath> and check them with L</subsumes>.
Current API available since 0.001.
=head2 children
@paths = path("/tmp")->children;
@paths = path("/tmp")->children( qr/\.txt\z/ );
Returns a list of C<Path::Tiny> objects for all files and directories
within a directory. Excludes "." and ".." automatically.
If an optional C<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.
=head2 chmod
path("foo.txt")->chmod(0777);
path("foo.txt")->chmod("0755");
path("foo.txt")->chmod("go-w");
path("foo.txt")->chmod("a=r,u+wx");
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 F</bin/chmod>.
The symbolic mode must be a comma-delimited list of mode clauses. Clauses must
match C<< qr/\A([augo]+)([=+-])([rwx]+)\z/ >>, which defines "who", "op" and
"perms" parameters for each clause. Unlike F</bin/chmod>, all three parameters
are required for each clause, multiple ops are not allowed and permissions
C<stugoX> are not supported. (See L<File::chmod> for more complex needs.)
Current API available since 0.053.
=head2 copy
path("/tmp/foo.txt")->copy("/tmp/bar.txt");
Copies the current path to the given destination using L<File::Copy>'s
C<copy> function. Upon success, returns the C<Path::Tiny> object for the
newly copied file.
Current API available since 0.070.
=head2 digest
$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 C<chunk_size>. If C<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 digest.
Any subsequent arguments are passed to the constructor for L<Digest> to select
an algorithm. If no arguments are given, the default is SHA-256.
Current API available since 0.056.
=head2 dirname (deprecated)
$name = path("/tmp/foo.txt")->dirname; # "/tmp/"
Returns the directory portion you would get from calling
C<< File::Spec->splitpath( $path->stringify ) >> or C<"."> for a path without a
parent directory portion. Because L<File::Spec> is inconsistent, the result
might or might not have a trailing slash. Because of this, this method is
B<deprecated>.
A better, more consistently approach is likely C<< $path->parent->stringify >>,
which will not have a trailing slash except for a root directory.
Deprecated in 0.056.
=head2 edit, edit_raw, edit_utf8
path("foo.txt")->edit( \&callback, $options );
path("foo.txt")->edit_utf8( \&callback );
path("foo.txt")->edit_raw( \&callback );
These are convenience methods that allow "editing" a file using a single
callback argument. They slurp the file using C<slurp>, place the contents
inside a localized C<$_> variable, call the callback function (without
arguments), and then write C<$_> (presumably mutated) back to the
file with C<spew>.
An optional hash reference may be used to pass options. The only option is
C<binmode>, which is passed to C<slurp> and C<spew>.
C<edit_utf8> and C<edit_raw> act like their respective C<slurp_*> and
C<spew_*> methods.
Current API available since 0.077.
=head2 edit_lines, edit_lines_utf8, edit_lines_raw
path("foo.txt")->edit_lines( \&callback, $options );
path("foo.txt")->edit_lines_utf8( \&callback );
path("foo.txt")->edit_lines_raw( \&callback );
These are convenience methods that allow "editing" a file's lines using a
single callback argument. They iterate over the file: for each line, the
line is put into a localized C<$_> variable, the callback function is
executed (without arguments) and then C<$_> 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
C<binmode>, which is passed to the method that open handles for reading and
writing.
C<edit_lines_raw> is like C<edit_lines> with a buffered C<binmode> of
C<:raw>.
C<edit_lines_utf8> is like C<edit_lines> with a buffered C<binmode>
C<:raw:encoding(UTF-8)> (or C<:raw:utf8_strict> with
L<PerlIO::utf8_strict>).

=head2 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.
B<Note>: C<is_file> is not C<-f> because C<-f> is not the opposite of C<-d>.
C<-f> means "plain file", excluding symlinks, devices, etc. that often can be
read just like files.
Use C<-f> instead if you really mean to check for a plain file.
Current API available since 0.053.
=head2 filehandle
$fh = path("/tmp/foo.txt")->filehandle($mode, $binmode);
$fh = path("/tmp/foo.txt")->filehandle({ locked => 1 }, $mode, $binmode);
$fh = path("/tmp/foo.txt")->filehandle({ exclusive => 1 }, $mode, $binmode);
Returns an open file handle. The C<$mode> argument must be a Perl-style
read/write mode string ("<" ,">", ">>", etc.). If a C<$binmode>
is given, it is set during the C<open> call.
An optional hash reference may be used to pass options.
The C<locked> option governs file locking; if true, handles opened for writing,
appending or read-write are locked with C<LOCK_EX>; otherwise, they are
locked with C<LOCK_SH>. When using C<locked>, ">" or "+>" modes will delay
truncation until after the lock is acquired.
The C<exclusive> option causes the open() call to fail if the file already
exists. This corresponds to the O_EXCL flag to sysopen / open(2).
C<exclusive> implies C<locked> and will set it for you if you forget it.
See C<openr>, C<openw>, C<openrw>, and C<opena> for sugar.
Current API available since 0.066.
=head2 has_same_bytes
if ( path("foo.txt")->has_same_bytes("bar.txt") ) {
# ...
}
This method returns true if both the invocant and the argument can be opened as
file handles and the handles contain the same bytes. It returns false if their
contents differ. If either can't be opened as a file (e.g. a directory or
non-existent file), the method throws an exception. If both can be opened and
both have the same C<realpath>, the method returns true without scanning any
data.
Current API available since 0.125.
=head2 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.
=head2 is_rootdir
while ( ! $path->is_rootdir ) {
$path = $path->parent;
...
}
Boolean for whether the path is the root directory of the volume. I.e. the
C<dirname> is C<q[/]> and the C<basename> is C<q[]>.
This works even on C<MSWin32> with drives and UNC volumes:
path("C:/")->is_rootdir; # true
path("//server/share/")->is_rootdir; #true
Current API available since 0.038.
=head2 iterator
$iter = path("/tmp")->iterator( \%options );
Returns a code reference that walks a directory lazily. Each invocation
returns a C<Path::Tiny> object or undef when the iterator is exhausted.
$iter = path("/tmp")->iterator;
while ( $path = $iter->() ) {
...
}
The current and parent directory entries ("." and "..") will not
be included.
If the C<recurse> option is true, the iterator will walk the directory
recursively, breadth-first. If the C<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,
} );
For a more powerful, recursive iterator with built-in loop avoidance, see
L<Path::Iterator::Rule>.

Current API available since 0.016.
=head2 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 C<binmode>, C<count> and C<chomp>.
If C<binmode> is provided, it will be set on the handle prior to reading.
If a positive C<count> is provided, that many lines will be returned from the
start of the file. If a negative C<count> is provided, the entire file will be
read, but only C<abs(count)> will be kept and returned. If C<abs(count)>
exceeds the number of lines in the file, all lines will be returned.
If C<chomp> is set, any end-of-line character sequences (C<CR>, C<CRLF>, or
C<LF>) will be removed from the lines returned.
Because the return is a list, C<lines> in scalar context will return the number
of lines (and throw away the data).
$number_of_lines = path("/tmp/foo.txt")->lines;
C<lines_raw> is like C<lines> with a C<binmode> of C<:raw>. We use C<:raw>
instead of C<:unix> so PerlIO buffering can manage reading by line.
C<lines_utf8> is like C<lines> with a C<binmode> of C<:raw:encoding(UTF-8)>
(or C<:raw:utf8_strict> with L<PerlIO::utf8_strict>). If L<Unicode::UTF8>
0.58+ is installed, a raw, unbuffered UTF-8 slurp will be done and then the
lines will be split. This is actually faster than relying on
IO layers, though a bit memory intensive. If memory use is a
concern, consider C<openr_utf8> and iterating directly on the handle.
Current API available since 0.065.
=head2 mkdir
path("foo/bar/baz")->mkdir;
path("foo/bar/baz")->mkdir( \%options );
Like calling C<make_path> from L<File::Path>. An optional hash reference
is passed through to C<make_path>. Errors will be trapped and an exception
thrown. Returns the the path object to facilitate chaining.
B<NOTE>: unlike Perl's builtin C<mkdir>, this will create intermediate paths
similar to the Unix C<mkdir -p> command. It will not error if applied to an
existing directory.
Current API available since 0.125.
=head2 mkpath (deprecated)
Like calling C<mkdir>, but returns the list of directories created or an empty list if
the directories already exist, just like C<make_path>.
Deprecated in 0.125.
=head2 move
path("foo.txt")->move("bar.txt");
Moves the current path to the given destination using L<File::Copy>'s
C<move> function. Upon success, returns the C<Path::Tiny> object for the
newly moved file.
If the destination already exists and is a directory, and the source is not a
directory, then the source file will be renamed into the directory
specified by the destination.
If possible, move() will simply rename the file. Otherwise, it
copies the file to the new location and deletes the original. If an
error occurs during this copy-and-delete process, you may be left
with a (possibly partial) copy of the file under the destination
name.
Current API available since 0.124. Prior versions used Perl's
-built-in (and less robust) L<rename|perlfunc/rename> function
and did not return an object.
=head2 openr, openw, openrw, opena
$fh = path("foo.txt")->openr($binmode); # read
$fh = path("foo.txt")->openr_raw;
$fh = path("foo.txt")->openr_utf8;
$fh = path("foo.txt")->openw($binmode); # write
$fh = path("foo.txt")->openw_raw;
$fh = path("foo.txt")->openw_utf8;
$fh = path("foo.txt")->opena($binmode); # append
$fh = path("foo.txt")->opena_raw;
$fh = path("foo.txt")->opena_utf8;
$fh = path("foo.txt")->openrw($binmode); # read/write
$fh = path("foo.txt")->openrw_raw;
$fh = path("foo.txt")->openrw_utf8;
Returns a file handle opened in the specified mode. The C<openr> style methods
take a single C<binmode> argument. All of the C<open*> methods have
C<open*_raw> and C<open*_utf8> equivalents that use buffered I/O layers C<:raw>
and C<:raw:encoding(UTF-8)> (or C<:raw:utf8_strict> with
L<PerlIO::utf8_strict>).
An optional hash reference may be used to pass options. The only option is
C<locked>. If true, handles opened for writing, appending or read-write are
locked with C<LOCK_EX>; otherwise, they are locked for C<LOCK_SH>.
$fh = path("foo.txt")->openrw_utf8( { locked => 1 } );
See L</filehandle> for more on locking.
Current API available since 0.011.
=head2 parent
$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 C<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. C<parent> by itself is equivalent to
C<parent(1)>.
Current API available since 0.014.
=head2 realpath
$real = path("/baz/foo/../bar")->realpath;
$real = path("foo/../bar")->realpath;
Returns a new C<Path::Tiny> object with all symbolic links and upward directory
parts resolved using L<Cwd>'s C<realpath>. Compared to C<absolute>, this is
more expensive as it must actually consult the filesystem.
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 L<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.
=head2 relative
$rel = path("/tmp/foo/bar")->relative("/tmp"); # foo/bar
Returns a C<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:
=over 4
=item *
If the original and new base path are on different volumes, an exception will be thrown.
=item *
If the original and new base are identical, the relative path is C<".">.
=item *
If the new base subsumes the original, the relative path is the original path with the new base chopped off the front
=item *
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 (C<"..">) to reach the common prefix, followed by the original path less the common prefix.
=back
Unlike C<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 components):
=over 4
=item *
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.
=item *
Symlinks in "B" don't change the result and will exist in the result as given.
=item *
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.
=back
Current API available since 0.001. New algorithm (that accounts for
symlinks) available since 0.079.
=head2 remove
path("foo.txt")->remove;
This is just like C<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.
=head2 remove_tree
# directory
path("foo/bar/baz")->remove_tree;
path("foo/bar/baz")->remove_tree( \%options );
path("foo/bar/baz")->remove_tree( { safe => 0 } ); # force remove
Like calling C<remove_tree> from L<File::Path>, but defaults to C<safe> mode.
An optional hash reference is passed through to C<remove_tree>. Errors will be
trapped and an exception thrown. Returns the number of directories deleted,
just like C<remove_tree>.
If you want to remove a directory only if it is empty, use the built-in
C<rmdir> function instead.
rmdir path("foo/bar/baz/");
Current API available since 0.013.
=head2 sibling
$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 C<Path::Tiny> object relative to the parent of the original.
This is slightly more efficient than C<< $path->parent->child(...) >>.
Current API available since 0.058.
=head2 size, size_human
my $p = path("foo"); # with size 1025 bytes
$p->size; # "1025"
$p->size_human; # "1.1 K"
$p->size_human( {format => "iec"} ); # "1.1 KiB"
Returns the size of a file. The C<size> method is just a wrapper around C<-s>.
The C<size_human> method provides a human-readable string similar to
C<ls -lh>. Like C<ls>, it rounds upwards and provides one decimal place for
single-digit sizes and no decimal places for larger sizes. The only available
option is C<format>, which has three valid values:
=over 4
=item *
'ls' (the default): base-2 sizes, with C<ls> style single-letter suffixes (K, M, etc.)
=item *
'iec': base-2 sizes, with IEC binary suffixes (KiB, MiB, etc.)
=item *
'si': base-10 sizes, with SI decimal suffixes (kB, MB, etc.)
=back
If C<-s> would return C<undef>, C<size_human> returns the empty string.
Current API available since 0.122.
=head2 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 C<binmode>, which is
passed to C<binmode()> on the handle used for reading.
C<slurp_raw> is like C<slurp> with a C<binmode> of C<:unix> for
a fast, unbuffered, raw read.
C<slurp_utf8> is like C<slurp> with a C<binmode> of
C<:unix:encoding(UTF-8)> (or C<:unix:utf8_strict> with
L<PerlIO::utf8_strict>). If L<Unicode::UTF8> 0.58+ is installed, a
unbuffered, raw slurp will be done instead and the result decoded with
C<Unicode::UTF8>. This is just as strict and is roughly an order of
magnitude faster than using C<:encoding(UTF-8)>.
B<Note>: C<slurp> and friends lock the filehandle before slurping. If
you plan to slurp from a file created with L<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.
=head2 spew, spew_raw, spew_utf8
path("foo.txt")->spew(@data);
path("foo.txt")->spew(\@data);
path("foo.txt")->spew({binmode => ":raw"}, @data);
path("foo.txt")->spew_raw(@data);
path("foo.txt")->spew_utf8(@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 C<binmode>, which is passed to
C<binmode()> on the handle used for writing.
C<spew_raw> is like C<spew> with a C<binmode> of C<:unix> for a fast,
unbuffered, raw write.
C<spew_utf8> is like C<spew> with a C<binmode> of C<:unix:encoding(UTF-8)>
(or C<:unix:utf8_strict> with L<PerlIO::utf8_strict>). If L<Unicode::UTF8>
0.58+ is installed, a raw, unbuffered spew will be done instead on the data
encoded with C<Unicode::UTF8>.
B<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 L</append> with the C<truncate> option.
Current API available since 0.011.
=head2 stat, lstat
$stat = path("foo.txt")->stat;
$stat = path("/some/symlink")->lstat;
Like calling C<stat> or C<lstat> from L<File::stat>.
Current API available since 0.001.
=head2 stringify
$path = path("foo.txt");
say $path->stringify; # same as "$path"
Returns a string representation of the path. Unlike C<canonpath>, this method
returns the path standardized with Unix-style C</> directory separators.
Current API available since 0.001.
=head2 subsumes
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 B<does not> resolve parent directory entries (C<..>) 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 C<realpath>:
my $p1 = path("foo/bar")->realpath;
my $p2 = path("foo/bar/../baz")->realpath;
if ( $p1->subsumes($p2) ) { ... }
Current API available since 0.048.
=head2 touch
path("foo.txt")->touch;
path("foo.txt")->touch($epoch_secs);
Like the Unix C<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
$content = path("foo.txt")->touch->slurp;
Current API available since 0.015.
=head2 touchpath
path("bar/baz/foo.txt")->touchpath;
Combines C<mkdir> and C<touch>. Creates the parent directory if it doesn't exist,
before touching the file. Returns the path object like C<touch> does.
If you need to pass options, use C<mkdir> and C<touch> separately:
path("bar/baz")->mkdir( \%options )->child("foo.txt")->touch($epoch_secs);
Current API available since 0.022.
=head2 visit
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 L</iterator> (which it uses internally):
C<recurse> and C<follow_symlinks>. Both default to false.
The callback function will receive a C<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 $path;
},
{ recurse => 1 }
);
For convenience, the C<Path::Tiny> object will also be locally aliased as the
C<$_> global variable:
# print paths matching /foo/
path("/tmp")->visit( sub { say if /foo/ }, { recurse => 1} );
If the callback returns a B<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 L<Path::Iterator::Rule>.
Current API available since 0.062.
=head2 volume
$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 L<File::Spec> would give from C<splitpath> and thus
usually is the empty string on Unix-like operating systems or the
drive letter for an absolute path on C<MSWin32>.

=head1 EXCEPTION HANDLING
Simple usage errors will generally croak. Failures of underlying Perl
functions will be thrown as exceptions in the class
C<Path::Tiny::Error>.
A C<Path::Tiny::Error> object will be a hash reference with the following fields:
=over 4
=item *
C<op> — a description of the operation, usually function call and any extra info
=item *
C<file> — the file or directory relating to the error

=head1 ENVIRONMENT
=head2 PERL_PATH_TINY_NO_FLOCK
If the environment variable C<PERL_PATH_TINY_NO_FLOCK> is set to a true
value then flock will NOT be used when accessing files (this is not
recommended).
=head1 CAVEATS
=head2 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.
=head2 Tilde expansion (deprecated)
Tilde expansion was a nice idea, but it can't easily be applied consistently
across the entire API. This was a source of bugs and confusion for users.
Therefore, it is B<deprecated> and its use is discouraged. Limitations to the
existing, legacy behavior follow.
Tilde expansion will only occur if the B<first> argument to C<path> begins with
a tilde. B<No other method does tilde expansion on its arguments>. If you want
tilde expansion on arguments, you must explicitly wrap them in a call to
C<path>.
path( "~/foo.txt" )->copy( path( "~/bar.txt" ) );
If you need a literal leading tilde, use C<path("./~whatever")> so that the
argument to C<path> doesn't start with a tilde, but the path still resolves to
the current directory.
Behaviour of tilde expansion with a username for non-existent users depends on
the output of C<glob> on the system.
=head2 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.
=head3 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.
=head3 Lustre
The Lustre filesystem does not support flock. If detected, this situation
will warn once, as described above.
=head3 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.
=head2 utf8 vs UTF-8
All the C<*_utf8> methods by default use C<:encoding(UTF-8)> -- either as
C<:unix:encoding(UTF-8)> (unbuffered, for whole file operations) or
C<:raw:encoding(UTF-8)> (buffered, for line-by-line operations). These are
strict against the Unicode spec and disallows illegal Unicode codepoints or
UTF-8 sequences.
Unfortunately, C<:encoding(UTF-8)> is very, very slow. If you install
L<Unicode::UTF8> 0.58 or later, that module will be used by some C<*_utf8>
methods to encode or decode data after a raw, binary input/output operation,
which is much faster. Alternatively, if you install L<PerlIO::utf8_strict>,
that will be used instead of C<:encoding(UTF-8)> and is also very fast.
If you need the performance and can accept the security risk,
C<< slurp({binmode => ":unix:utf8"}) >> will be faster than C<:unix:encoding(UTF-8)>
(but not as fast as C<Unicode::UTF8>).
Note that the C<*_utf8> methods read in B<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
=head2 Default IO layers and the open pragma
If you have Perl 5.10 or later, file input/output methods (C<slurp>, C<spew>,
etc.) and high-level handle opening methods ( C<filehandle>, C<openr>,
C<openw>, etc. ) respect default encodings set by the C<-C> switch or lexical
L<open> settings of the caller. For UTF-8, this is almost certainly slower
than using the dedicated C<_utf8> methods if you have L<Unicode::UTF8> or
L<PerlIP::utf8_strict>.
