[ANN] data.int-map 0.2.0

https://github.com/clojure/data.int-map The 0.1.0 release of this library was a faithful Clojure implementation of Okasaki's "Fast Mergeable Integer Maps" paper [1]. While it was much faster than Clojure's sorted-maps, it was in some cases slower than hash-maps, which was mostly due to the int

Re: How can I remove this "nil?" check from my code?

It seems like, if you don't mind doing the assoc all the time, you could replace the whole if with something like: (assoc nu (:winner c) (or ((:winner c) nu) {:history [{}]})) You might want to wrap that in a let so you don't repeat (:winner c). Also, it looks like add-placeholder-to-history cou

Re: Relational mapping - turning an sql query result into array of hashes (with joins)

It's interesting how this question pops up every now and again. I find that, for the types of projects I work with, I'm perfectly happy writing little combinators to work with result sets myself. At one project though, a standard RESTful web application with a traditional relational model, I ended

How can I remove this "nil?" check from my code?

I started to write an essay, aimed at those programmers who are experienced with highly mutable languages such as Javascript, Ruby, PHP, etc, to demonstrate how one's code style changes when one switches to a mostly immutable language such as Clojure. However, my Clojure code is not nearly as

Yes, sir. Well understood. On top of that, the announcement was mistaken. System's version is at 0.1.8, not 0.0.8. Will do better next time. On Tuesday, May 26, 2015 at 3:49:05 AM UTC+3, Michael Klishin wrote: > > On 26 May 2015 at 03:45:04, Daniel Szmulewicz (daniel.s...@gmail.com > ) wrot

Thank you pointing this out. Is there a consensus as to what versioning scheme works best? Or is there no such beast? Peter Taoussanis has expressed some reservations regarding SemVer and is proposing a variation on it, which he calls BreakVer. https://github.com/ptaoussanis/encore/blob/master

Re: Relational mapping - turning an sql query result into array of hashes (with joins)

Actually I wasn't going there to ORMs. I don't think I'm going any where, but I'm having a good time any way. I do share your thought that ORMs are neither necessary nor sufficient for these problems. My recent somewhat functional adventures in this domain is within the realm of Racket. There

Re: what demonstrates Stuart Sierra's "State/Event Pattern"

Stuart Sierra, Thank you for the response. I won't take that talk as encyclopedic. The 'chain-consequences' function is very interesting, though it is unfamiliar to me. I am still learning about Clojure. You mention that the State/Event pattern is a common one. If you were talking about archi

Re: Relational mapping - turning an sql query result into array of hashes (with joins)

Thanks Daniel, and Sean for your answers. Daniel, the part that interests me the most is "converting resultset rows to collection (of objects)", and I think a lot of people do just what you said (own customized function). I was looking for, and will probably in the end implement an open source

[ANN]: Matcha, a library for composable test assertions with human readable error messages

Matcha lets you write flexible, composable test assertions with human friendly error messages. It's modeled after the excellent Java Hamcrest library. As a quick example, you might build up a matcher that says "this map has 5 elements, and the :foo key must be greater than 10" like so: ``` (re

Re: Relational mapping - turning an sql query result into array of hashes (with joins)

I just don’t consider it a problem. A query returns a flat result set — a sequence of hash-maps. That’s it. That’s what SQL returns (essentially a table) and it’s a perfectly reasonable data structure for Clojure to work with. The JOINs in SQL just say how to link tables together to produce that

This is a pattern I have used **occasionally**. That whole talk is just patterns that were in my head at the time. Take whatever you find useful from it, but don't treat it as a universal or complete list. If you squint, that 'chain-consequences' function behaves sort of like a monad, but I wo
