NAMEDancer::Error - class for representing fatal errorsVERSIONversion 1.3513SYNOPSIS# taken from send_file: use Dancer::Error; my $error = Dancer::Error->new( code => 404, message => "No such file: `$path'" ); $error->render; DESCRIPTIONWith 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. ATTRIBUTEScodeThe code that caused the error.This is only an attribute getter, you'll have to set it at "new". titleThe title of the error page.This is only an attribute getter, you'll have to set it at "new". messageThe message of the error page.This is only an attribute getter, you'll have to set it at "new". exceptionThe exception that caused the error. If the error was not caused by an exception, returns undef. Exceptions are usually objects that inherit from Dancer::Exception.This is only an attribute getter, you'll have to set it at "new". METHODS/SUBROUTINESnewCreate 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. backtraceCreate 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-highlighted "message". tabulateSmall subroutine to help output nicer.dumperThis uses Data::Dumper to create nice content output with a few predefined options.renderRenders a response using Dancer::Response.environmentA main function to render environment information: the caller (using "get_caller"), the settings and environment (using "dumper") and more.get_callerCreates a stack trace of callers._censorAn internal method that tries to censor out content which should be protected."dumper" calls this method to censor things like passwords and such. _html_encodeInternal 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 any more, output can be any charset.
