Hi Reid, I dig how nicely it integrates with clojure.test. Does simple-check implement some form of shrinking? On Tue, Jul 16, 2013 at 12:20 PM, Reid Draper reiddra...@gmail.com wrote: Derp, I fat-fingered my own library name in the subject :) On Tuesday, July 16, 2013 2:18:54 PM UTC-5,

ANN: testselector

At work I noticed that every once in a while we'd forget to add test selectors to our tests, which means that they may not get executed by CI. To prevent this I wrote testselector as a way to periodically check that all deftests have one of the expected metadatas present. It is really simple to

Re: Can't figure out how to merge this dern map.

Agreed that it is weird and I never use `into` in that manner, either. On Mon, Jul 8, 2013 at 9:50 AM, Gary Trakhman gary.trakh...@gmail.comwrote: Into is reduce-conj, and this relies on a special-case of conj for maps and map entries. I find it hard to read, so I would vote for apply/reduce

Re: Domain modelling question

Hi Marc, But the domain model I'm thinking of has lots of mutable things that change over time when I execute the business actions. In your case, you don't need any STM to model any of your domain. I'd go so far as to say that to use refs for this is almost certainly a mistake. Of course the

Re: core.async

Very cool stuff. One point of feedback though: I thought Clojure Core had done a great job of avoiding a Haskell-like symbol-heavy. I might've been mis-informed, but I thought this tendency to avoid symbol-heavy naming was intentional. For example, instead of `-?` in 1.5 we got `some-`. I

Re: Database migrations

Inspired by Technomancy's suggestion to try a simpler approach to migrations on IRC, I came up with this tiny library based heavily on code from the clojars repo, that Phil pointed me to. Personally, I thought Ragtime and Lobos, were overkill.

There are things I love and hate about both Emacs and Intellij, so after a year of working professionally with a bunch of Clojure-Emacs users, I still end up using Intellij about half the time, and get my fair share of harassment over it. I'd like to merge the two actually if possible. On Tue,

Re: alter a map in a vector (reference)

You *can* update this inside the vector, but if you want to key by :id, I would personally recommend, you put the email data into a map and look it up by :id, like this: {1 {:id 1 :email {a...@mail.com 1}} 2 {:id 2 :email {d...@mail.com 1}} 3 {:id 3 :email {g...@mail.com 2}}} Best, Alex On
