Hi Khalid, Reflections [1] are a big problem too for Graalvm. Here is a thread of playing with Clojure and Graalvm [2]. If you follow the links, you will see some issues I ran into. Hth, Jeroen [1] Ones that are and aren't caught by *warn-on-reflections*

Re: Using clojure.spec for api migrations?

Oh I meant `clojure.spec/gen` instead of `clojure.spec/with-gen`. `clojure.spec/gen` has an overrides option. I (think I) need something like this to cleanly change the unforming action in a nested spec. Jeroen On Tue, Sep 6, 2016 at 8:00 PM, Jeroen van Dijk <jeroentjevand...@gmail.com>

Using clojure.spec for api migrations?

Hi, I'm playing with the idea of using clojure.spec to make an API backwards compatible by using conform and unform to transform data from the old version format to a new format version. Below is an example of this in code: Say we have API change that involves changing the name of a nested key:

clojure.spec generation question

I'm trying to generate logical predicates in order to test a function that should return the predicate in DNF. The generation seems to be biased towards one of the predicates. What am I doing wrong? (require '[clojure.spec :as s]) (require '[clojure.spec.gen :as gen]) (s/def ::atom string?)

This could be a nice example of how to use component in practise: https://github.com/bevuta/pepa Internally we configure the system map differently. This is based on yet another library https://github.com/RedBrainLabs/system-graph We have extended the idea of this library and we now have a file

Re: Weird behaviour in re-matches ?

Looks like something in re-matches is printing the second argument, but without a terminating newline. A subsequent print, such as of nil\n or (1 2)\n, by the REPL evaluator, with a newline, then completes the line and flushes the output buffer. There seem to be three separate errors here,

Weird behaviour in re-matches ?

I came accross this weird case below with re-matches (in clojure 1.6). For some reason the pattern matches, once just once, only after a parse exception. This pattern repeats with every follow up parse exception. Is this a known bug? It seems to be related with the pending newline too. user=

Re: Actually using component.

I think the most important rule when using component is to only use local state like Timothy stated, i.e. nothings gets def-ed. You could write an application that a -main function that starts the system and you would never need a global reference to the system. In practise however, you do make

Thanks for sharing James! I'll have a look. As a side note, I see in the example code that you are dissoc-ing on the component. This can lead to unexpected behaviour as I have experienced (mostly in repl cases), as this will return a map instead of a record when the field is not part of the
