NAME Path::Tiny - File path utility VERSION version 0.001 SYNOPSIS use Path::Tiny; # creating Path::Tiny objects $dir = path("/tmp"); $foo = path("foo.txt"); $subdir = $dir->child("foo"); $bar = $subdir->child("bar.txt"); # reading files $guts = $file->slurp; $guts = $file->slurp_utf8; @lines = $file->lines; @lines = $file->lines_utf8; $head = $file->lines( {count => 1} ); # writing files $bar->spew( @data ); $bar->spew_utf8( @data ); # reading directories for ( $dir->children ) { ... } $iter = $dir->iterator; while ( my $next = $iter->() ) { ... } DESCRIPTION This module attempts to provide 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 doesn't attempt to be as full-featured as IO::All or Path::Class, nor does it 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 Win32?) All paths are forced to have Unix-style forward slashes. Stringifying the object gives you back the path (after some clean up). CONSTRUCTORS path $path = path("foo/bar"); $path = path("/tmp/file.txt"); $path = path(); # like path(".") 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. new $path = Path::Tiny->new("foo/bar"); This is just like "path", but with method call overhead. (Why would you do that?) rootdir $path = Path::Tiny->rootdir; # / Gives you "File::Spec->rootdir" as a "Path::Tiny" object if you're too picky for "path("/")". tempfile $temp = Path::Tiny->tempfile( @options ); This passes the options to "File::Temp->new" and returns a "Path::Tiny" object with the file name. If you want a template, you must use a "TEMPLATE" named argument. 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. tempdir $temp = Path::Tiny->tempdir( @options ); This is just like "tempfile", except it calls "File::Temp->newdir" instead. METHODS absolute $abs = path("foo/bar")->absolute; $abs = path("foo/bar")->absolute("/tmp"); Returns a new "Path::Tiny" object with an absolute path. Unless an argument is given, the current directory is used as the absolute base path. The argument must be absolute or you won't get an absolute result. append path("foo.txt")->append(@data); path("foo.txt")->append({binmode => ":raw"}, @data); Appends data to a file. The file is locked with "flock" prior to writing. 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 writing. append_utf8 path("foo.txt")->append_utf8(@data); This is like "append" with a "binmode" of ":encoding(UTF-8)". basename $name = path("foo/bar.txt")->basename; # bar.txt Returns the file portion or last directory portion of a path. child $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 directories. children @paths = path("/tmp")->children; Returns a list of "Path::Tiny" objects for all file and directories within a directory. Excludes "." and ".." automatically. copy path("/tmp/foo.txt")->copy("/tmp/bar.txt"); Copies a file using File::Copy's "copy" function. dirname $name = path("/tmp/foo.txt")->dirname; # "/tmp/" Returns the directory name portion of the path. This is roughly equivalent to what File::Spec would give from "splitpath" and thus usually has the trailing slash. If that's not desired, stringify directories or call "parent" on files. exists if ( path("/tmp")->exists ) { ... } Just like "-e". filehandle $fh = path("/tmp/foo.txt")->filehandle($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 passed to "binmode" on the handle. See "openr", "openw", "openrw", and "opena" for sugar. is_absolute if ( path("/tmp")->is_absolute ) { ... } Boolean for whether the path appears absolute or not. is_dir if ( path("/tmp")->is_dir ) { ... } Just like "-d". This means it actually has to exist on the filesystem. Until then, it's just a path. is_file if ( path("/tmp")->is_file ) { ... } Just like "-f". This means it actually has to exist on the filesystem. Until then, it's just a path. is_relative if ( path("/tmp")->is_relative ) { ... } Boolean for whether the path appears relative or not. iterator $iter = path("/tmp")->iterator; while ( $path = $iter->() ) { ... } Returns a code reference that walks a directory lazily. Each invocation returns a "Path::Tiny" object or undef when the iterator is exhausted. This iterator is not recursive. For recursive iteration, use Path::Iterator::Rule instead. lines @contents = path("/tmp/foo.txt")->lines; @contents = path("/tmp/foo.txt")->lines(\%options); 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 reading. If "count" is provided, up to that many lines will be returned. If "chomp" is set, lines will be chomped before being returned. lines_utf8 @contents = path("/tmp/foo.txt")->lines_utf8; @contents = path("/tmp/foo.txt")->lines({chomp => 1}); This is like "lines" with a "binmode" of ":encoding(UTF-8)". lstat $stat = path("/some/symlink")->lstat; Like calling "lstat" from File::stat. mkpath path("foo/bar/baz")->mkpath; path("foo/bar/baz")->mkpath( \%options ); Like calling "make_path" from File::Path. An optional hash reference is passed through to "make_path". move path("foo.txt")->move("bar.txt"); Just like "rename". openr, openw, openrw, opena $fh = path("foo.txt")->openr($binmode); # read $fh = path("foo.txt")->openr_utf8; $fh = path("foo.txt")->openw($binmode); # write $fh = path("foo.txt")->openw_utf8; $fh = path("foo.txt")->opena($binmode); # append $fh = path("foo.txt")->opena_utf8; $fh = path("foo.txt")->openrw($binmode); # read/write $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*_utf8" equivalents that use ":encoding(UTF-8)". parent $parent = path("foo/bar/baz")->parent; # foo/bar $parent = path("foo/wibble.txt")->parent; # foo Returns a "Path::Tiny" object corresponding to the parent directory of the original directory or file. relative $rel = path("/tmp/foo/bar")->relative("/tmp"); # foo/bar Returns a "Path::Tiny" object with a relative path name. Given the trickiness of this, it's a thin wrapper around "File::Spec->abs2rel()". remove # directory path("foo/bar/baz")->remove; path("foo/bar/baz")->remove( \%options ); # file path("foo.txt")->remove; For directories, this is like like calling "remove_tree" from File::Path. An optional hash reference is passed through to "remove_tree". For files, the file is unlinked if it exists. Unlike "unlink", if the file does not exist, this silently does nothing and returns a true value anyway. slurp $data = path("foo.txt")->slurp; $data = path("foo.txt")->slurp( {binmode => ":raw"} ); Reads file contents into a scalar. Takes 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 reading. slurp_utf8 $data = path("foo.txt")->slurp_utf8; This is like "slurp" with a "binmode" of ":encoding(UTF-8)". spew path("foo.txt")->spew(@data); 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 writing. spew_utf8 path("foo.txt")->spew_utf8(@data); This is like "spew" with a "binmode" of ":encoding(UTF-8)". stat $stat = path("foo.txt")->stat; Like calling "stat" from File::stat. stringify $path = path("foo.txt"); say $path->stringify; # same as "$path" Returns a string representation of the path. touch path("foo.txt")->touch; 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. volume $vol = path("/tmp/foo.txt")->volume; Returns the volume portion of the path. This is equivalent equivalent to what File::Spec would give from "splitpath" and thus usually is the empty string on Unix-like operating systems. SEE ALSO * File::Fu * IO::All * Path::Class Probably others. Let me know if you want me to add a module to the list. BENCHMARKING I benchmarked a naive file-finding task: finding all "*.pm" files in @INC. I tested Path::Iterator::Rule and different subclasses of it that do file manipulations using file path helpers Path::Class, IO::All, File::Fu and "Path::Tiny". Path::Iterator::Rule 0.474s (no objects) Path::Tiny::Rule 0.938s (not on CPAN) IO::All::Rule 1.355s File::Fu::Rule 1.437s (not on CPAN) Path::Class::Rule 4.673s This benchmark heavily stressed object creation and determination of a file's basename.
