Cider: [exceptions] Potential improvement for `*cider-error*` buffers
Prone is a helpful library for debugging clojure/ring web applications.
A great feature of Prone is their display of stack traces, a lot of typically useless and distracting information is elided. I was reading about how they achieved that:
https://github.com/magnars/prone#how-does-prone-determine-what-parts-of-a-stack-trace-belongs-to-the-application
(they do some sort of filtering on the namespaces)
I wonder if something similar would be possible/good in Cider? The existing stacktrace/error functionality is sophisticated, useful, and a key part of my day to day work already; but I think additional filtering could still help.
Thanks again for Cider, I can't mention enough how lovely and great it is.

Basically you want some toggle that just displays only the application stack frames?

Yes: filtering out libraries and clojure/core, etc. Does that sound right to you?

Yeah, it does. As we already have a filtering mechanism in place I'm assuming that extending it to account just for application frames should be easy.

The pull request to cider-nrepl above will flag frames with 'project.
Adding a filter in the method of the others does not accomplish what we want though. They are negative filters in the sense that they remove frames marked with the symbol given. We need a different notion of a filter that removes the _complement_ of the button hit. Shouldn't be hard but doesn't just plug right in. I'll get on this as soon as the clojure side pull request is up to snuff and accepted.

Mmm, I like where this is headed. Let me know if there's more I can do to help.

@dpsutton Hasn't the "negative" filter been implemented as Show instead of Hide?
@harold Can this be closed? Or do you have some other filters in mind?

Woah. I just clicked Project-Only for the first time, and good things happened! Great work, all.
I will experiment with this more in more real-world use and see how it goes.
I have no problem closing this, future thoughts can be put into new issues.
Thanks again all.
