Dancer::Error(3pm) User Contributed Perl Documentation Dancer::Error(3pm) NAME
Dancer::Error - class for representing fatal errors SYNOPSIS
# taken from send_file: use Dancer::Error; my $error = Dancer::Error->new( code => 404, message => "No such file: `$path'" ); Dancer::Response->set($error->render); DESCRIPTION
With Dancer::Error you can throw reasonable-looking errors to the user instead of crashing the application and filling up the logs. This is usually used in debugging environments, and it's what Dancer uses as well under debugging to catch errors and show them on screen. ATTRIBUTES
code The code that caused the error. This is only an attribute getter, you'll have to set it at "new". title The title of the error page. This is only an attribute getter, you'll have to set it at "new". message The message of the error page. This is only an attribute getter, you'll have to set it at "new". exception The exception that caused the error. If the error was not caused by an exception, returns undef. Exceptions are usually objects that inherits of Dancer::Exception. This is only an attribute getter, you'll have to set it at "new". METHODS
/SUBROUTINES new Create a new Dancer::Error object. title The title of the error page. type What type of error this is. code The code that caused the error. message The message that will appear to the user. exception The exception that will be useable by the rendering. backtrace Create a backtrace of the code where the error is caused. This method tries to find out where the error appeared according to the actual error message (using the "message" attribute) and tries to parse it (supporting the regular/default Perl warning or error pattern and the Devel::SimpleTrace output) and then returns an error- higlighted "message". tabulate Small subroutine to help output nicer. dumper This uses Data::Dumper to create nice content output with a few predefined options. render Renders a response using Dancer::Response. environment A main function to render environment information: the caller (using "get_caller"), the settings and environment (using "dumper") and more. get_caller Creates a strack trace of callers. _censor An internal method that tries to censor out content which should be protected. "dumper" calls this method to censor things like passwords and such. _html_encode Internal method to encode entities that are illegal in (X)HTML. We output as UTF-8, so no need to encode all non-ASCII characters or use a module. FIXME : this is not true anymore, output can be any charset. Need fixing. AUTHOR

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. AUTHOR
