Support for Flame framework

[AlexWayfer]

Hello!

I have the Flame framework (Rack-based).

And this gem does not work as middleware.

Can you please describe (add to documentation/wiki) what is required for integration? Like raising exception, or 500 status…

Can you elaborate? BetterErrors is Rack middleware.

I've read this. I've added this code:

require "better_errors"

if ENV["RACK_ENV"] == "development"
  use BetterErrors::Middleware
end

And no changes, 500 is caught by Flame framework.

I've asked about documentation for framework developers, mentioned documentation looks like for users (apps developers).

If you're using a framework that rescues errors, then the error won't make it to the Better Errors middleware. I'm pretty sure that's what's happening here. The order of middleware is important; with Rails middleware, Better Errors has to place itself in just the right place in order to do its job.

I'm not a Rack middleware expert unfortunately, but I'll try to find time to dig into it soon.

Thank you! I'd glad to know how to place Better Errors in the right place. I'll try to do it later with my own Rack-based framework (Flame). Probably, it should work like:

• Code of web-app raises error
• It goes through web-framework, through call method, to rack-middleware (Better Errors)

And currently it may fails due to rescuing errors in web-framework (Flame) without re-raising: https://github.com/AlexWayfer/flame/blob/3792cbb04d46ca8ac92a0122d4e9f7e01cae2db9/lib/flame/dispatcher/routes.rb#L33-L39

I'll check it later.

OK, I actually can integrate better_errors just via re-raising exception when BetterErrors constant is defined, thank you!

Small side question: why I see "no application frames available"? Can I improve this somehow? On what it depends?

[RobinDaugherty]

Application frames are determined based on BetterErrors.application_root. You can see an example of how to set this here.

Thank you, it seems working!

I want to add Flame to the referenced documentation, if you'd allow, if so I suggest to leave this issue open and even you can assign it to me. Ability to integration of Flame with Better Errors will be in long-awaited 5 release (there are already RC versions).
