In response to this reddit post about failing to understand the Pipes library after a couple of hours. I wanted to show how an experienced haskeller does it, but I'm afraid it also took me quite a few hours, which is why the following list of steps goes on and on.

After all those hours, my opinion is that Pipes is not at all an easy library. I don't know if Conduit is any easier, but otherwise I side with your friend in advising to use something else (perhaps ordinary lazy IO?) instead of Pipes.

Anyway, here is the full brain dump of my steps as I tried to get your three snippets to fit together.

• Since you say that you have a hard time combining the snippets, I assume that they must have complicated types. So my first goal is to figure out the type of your first snippet.
• hoogle for parseUrl, withManager, etc. No results.
• Google for haskell runEffect, find that it's a method from Pipes.Core,

Prevent transition when a form is half filled out

If you've filled out some fields in a navigate elsewhere, either via a back button, URL change, or linkTo transition, there should be a way to intercept that transition and make the user confirm they want to perform the transition.

Answer

Use routeTo handler on form route. Bubble the event if user confirms navigation.

Delayed "Twitter" transition, regardless of URL navigation / transitionTo

Check out the progress on redirectable/preventable transitions.

This consists almost entirely of a rewrite of router.js, with hardly any changes to the Ember codebase. Lots of things have been added router-wise, but this particular demo focuses on how attempted transitions can be intercepted/redirected/prevented/decorated by defining transition event handlers in a transitions hash on Ember.Route. I also added support for URL-less routes (see the URL-less States Demo at the top in the link below). You can test this out yourself with this branch of Ember, which has the new router.js code i've been working on in it.

I ended up reusing the Emblem test app, so try not to be distracted by the template syntax stuff (sorry, twas most readily available for trying this new transition code). You can check out the code for this transition demo here. Below I've highlighted the m

Transition Handlers for Ember Router

Proposal

Add transitions hash to Ember.Route, which contains transition handlers for preventing/redirecting/decorating attempted transitions, whether initiated by transitionTo or URL change (handleURL).

Rationale

1. Seal the app from unconstrained URL changes breaking your app's state machine
2. Bring back router v1's state-based patterns while maintaining v2's lovely DSL for defining routes

# If you're having cert issues on ruby 2.0.0-p0, the issue is most likely that ruby can't

# When ruby-build installs openssl, it installs the CA certs here:
~/.rbenv/versions/2.0.0-p0/openssl/ssl/cacert.pem

# Ruby is expecting them here:
$(ruby -ropenssl -e 'puts OpenSSL::X509::DEFAULT_CERT_FILE')
