NAME
File::Fu::File - a filename object
SYNOPSIS
use File::Fu; my $file = File::Fu->file("path/to/file"); $file %= '.extension'; $file->e and warn "$file exists"; $file->l and warn "$file is a link to ", $file->readlink;
Constructor
new my $file = File::Fu::File->new($path); my $file = File::Fu::File->new(@path); new_direct my $file = File::Fu::File->new_direct( dir => $dir_obj, file => $name );
Class Constants
dir_class Return the corresponding dir class for this file object. Default: File::Fu::Dir. my $dc = $class->dir_class; is_dir Always false for a file. is_file Always true for a file.
Parts
basename Returns a new object representing only the file part of the name. my $obj = $file->basename;
Methods
stringify my $string = $file->stringify; append Append a string only to the filename part. $file->append('.gz'); $file %= '.gz'; (Yeah... I tried to use .=, but overloading hates me.) map $file->map(sub {...}); $file &= sub {...}; absolute Get an absolute name (without checking the filesystem.) my $abs = $file->absolute; absolutely Get an absolute name (resolved on the filesytem.) my $abs = $file->absolutely;
Doing stuff
open Open the file with $mode ('<', 'r', '>', 'w', etc) -- see IO::File. my $fh = $file->open($mode, $permissions); Throws an error if anything goes wrong or if the resulting filehandle happens to be a directory. sysopen Interface to the sysopen() builtin. The value of $mode is a text string joined by '|' characters which must be valid O_* constants from Fcntl. my $fh = $file->sysopen($mode, $perms); piped_open Opens a read pipe. The file is appended to @command. my $fh = $file->piped_open(@command); Example: useless use of cat. my $fh = $file->piped_open('cat'); This interface is deprecated (maybe) because it is limited to commands which take the $file as the last argument. See run() for the way of the future. run Treat $file as a program and execute a pipe open. my $fh = $file->run(@args); If called in void context, runs "system()" with autodie semantics and multi-arg form (suppresses shell interpolation.) $file->run(@args); No special treatment is made for whether $file is relative or not (the underlying "system()"/"exec()" will search your path.) Use File::Fu->which() to get an absolute path beforehand. File::Fu->which('ls')->run('-l'); touch Update the timestamp of a file (or create it.) $file->touch; mkfifo my $file = $file->mkfifo($mode); link my $link = $file->link($name); symlink my $link = $file->symlink($linkname); Note that symlinks are relative to where they live. my $dir = File::Fu->dir("foo"); my $file = $dir+'file'; # $file->symlink($dir+'link'); is a broken link my $link = $file->basename->symlink($dir+'link'); relative_symlink See "relative_symlink" in File::Fu::Base. unlink $file->unlink; remove A forced unlink (chmod the file if it is not writable.) $file->remove; readlink my $to = $file->readlink; read Read the entire file into memory (or swap!) my @lines = $file->read; my $file = $file->read; If File::Slurp is available, options to read_file will be passed along. See "read_file" in File::Slurp. write Write the file's contents. Returns the $file object for chaining. $file = $file->write($content); If File::Slurp is available, $content may be either a scalar, scalar ref, or array ref. $file->write($content, %args); copy Copies $file to $dest (which can be a file or directory) and returns the name of the new file as an object. my $new = $file->copy($dest); Note that if $dest is already a File object, that existing object will be returned. move my $new = $file->move($dest);
