Dancer::FileUtils - File utility helpers
version 1.9999_01
use Dancer::FileUtils qw/dirname path path_or_empty/; # for 'path/to/file' my $dir = dirname($path); # returns 'path/to' my $path = path($path); # returns '/abs/path/to/file' my $path = path_or_empty($path); # returns '' if file doesn't exist 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, '<', $file or die "$!\n"; set_file_mode($fh); my @content = read_file_content($fh); my $content = read_file_content($fh); use Dancer::FileUtils qw/open_file/; my $fh = open_file('<', $file) or die $message; use Dancer::FileUtils 'set_file_mode'; set_file_mode($fh);
Dancer::FileUtils includes a few file related utilities that Dancer uses internally. Developers may use it instead of writing their own file reading subroutines or using additional modules.
Provides comfortable path resolution, internally using File::Spec. 'path' does not verify paths, it just normalizes the path.
Like path, but returns '' if path doesn't exist.
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.
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.
use Dancer::FileUtils 'open_file'; my $fh = open_file('<', $file) or die $message;
Calls open and returns a filehandle. Takes in account the 'charset' setting from Dancer's configuration to open the file in the proper encoding (or defaults to utf-8 if setting not present).
use Dancer::FileUtils 'read_file_content'; my @content = read_file_content($file); my $content = read_file_content($file);
Returns either the content of a file (whose filename is the input), or undef if the file could not be opened.
In array context it returns each line (as defined by $/) as a seperate element; in scalar context returns the entire contents of the file.
use Dancer::FileUtils 'read_glob_content'; open my $fh, '<', $file or die "$!\n"; 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.
Nothing by default. You can provide a list of subroutines to import.
