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, '<', $file or die "$!\n";
    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, '<', $file or die "$!\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.

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.
