Dancer::Error - class for representing fatal errors
# taken from send_file:
my $error = Dancer::Error->new(
code => 404,
message => "No such file: `$path'"
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.
The code that caused the error.
This is only an attribute getter, you'll have to set it at new.
The title of the error page.
The message of the error page.
The 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.
Create a new Dancer::Error object.
What type of error this is.
The message that will appear to the user.
The exception that will be useable by the rendering.
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-highlighted message.
Small subroutine to help output nicer.
This uses Data::Dumper to create nice content output with a few predefined options.
Renders a response using Dancer::Response.
A main function to render environment information: the caller (using get_caller), the settings and environment (using dumper) and more.
Creates a stack trace of callers.
An internal method that tries to censor out content which should be protected.
dumper calls this method to censor things like passwords and such.
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 any more, output can be any charset. Need fixing.
