dancer::fileutils
Dancer::FileUtils(3pm) User Contributed Perl Documentation Dancer::FileUtils(3pm)NAME
Dancer::FileUtils - helper providing file utilities
SYNOPSIS
use Dancer::FileUtils qw/dirname path/;
# for 'path/to/file'
my $dir = dirname($path); # returns 'path/to'
my $path = path($path); # returns '/abs/path/to/file'
use Dancer::FileUtils qw/path read_file_content/;
my $content = read_file_content( path( 'folder', 'folder', 'file' ) );
my @content = read_file_content( path( 'folder', 'folder', 'file' ) );
use Dancer::FileUtils qw/read_glob_content set_file_mode/;
open my $fh, '<', $file or die "$!
";
set_file_mode($fh);
my @content = read_file_content($fh);
my $content = read_file_content($fh);
DESCRIPTION
Dancer::FileUtils includes a few file related utilities related that Dancer uses internally. Developers may use it instead of writing their
own file reading subroutines or using additional modules.
SUBROUTINES /METHODS
dirname
use Dancer::FileUtils 'dirname';
my $dir = dirname($path);
Exposes File::Basename's dirname, to allow fetching a directory name from a path. On most OS, returns all but last level of file path. See
File::Basename for details.
open_file
use Dancer::FileUtils 'open_file';
my $fh = open_file('<', $file) or die $message;
Calls open and returns a filehandle. Takes in account the 'charset' setting from Dancer's configuration to open the file in the proper
encoding (or defaults to utf-8 if setting not present).
path
use Dancer::FileUtils 'path';
my $path = path( 'folder', 'folder', 'filename');
Provides comfortable path resolving, internally using File::Spec.
read_file_content
use Dancer::FileUtils 'read_file_content';
my @content = read_file_content($file);
my $content = read_file_content($file);
Returns either the content of a file (whose filename is the input), undef if the file could not be opened.
In array context it returns each line (as defined by $/) as a separate element; in scalar context returns the entire contents of the file.
read_glob_content
use Dancer::FileUtils 'read_glob_content';
open my $fh, '<', $file or die "$!
";
my @content = read_glob_content($fh);
my $content = read_glob_content($fh);
Same as read_file_content, only it accepts a file handle. Returns the content and closes the file handle.
set_file_mode
use Dancer::FileUtils 'set_file_mode';
set_file_mode($fh);
Applies charset setting from Dancer's configuration. Defaults to utf-8 if no charset setting.
EXPORT
Nothing by default. You can provide a list of subroutines to import.
