README
Exception Page 
A library for displaying exceptional exception pages for easier debugging.
Installation
Add this to your application's shard.yml
:
dependencies:
exception_page:
github: crystal-loot/exception_page
Usage
Require the shard:

Create an exception page:

)
end
end
Render the HTML when an exception occurs:
class MyErrorHandler
include HTTP::Handler
def call_next(context)
begin
# Normally you'd call some code to handle the request
# We're hard-coding an error here to show you how to use the lib.
raise SomeError.new("Something went wrong")
rescue e
context.response.status_code = 500
context.response.print MyApp::ExceptionPage.for_runtime_exception(context, e).to_s
end
end
