In this article, I’ll evaluate the Emacs, Cursive, and Spacemacs_, and explain why I ended up with_ Spacemacs for most of the projects I’m currently working on.
In the last post, I discussed my Clojure learning strategy in general and introduced my new hobby project My Bookshelf.
In this post, I’ll discuss the general learning strategy and show an example how to apply it to Learning the Clojure programming language.
Last week, I was quite happy to attend (:brno Clojure) meetup. There were only five people including me. Nevertheless, we had a great time and covered a lot of topics. There was no main theme, just live free and spontaneous discussion about our experience with Clojure. We discussed following topics:
server-side template duct
easy-to-use template for getting started with Clojure web applications
how is it different from chestnut?
Karel Miarka’s own project
Uses Datomic
Emacs/Spacemacs vs. Cursive
Spacemacs has lots of preconfigured plugins => easier to use than plain Emacs
Korma SQL
macro magic
consider using something else (Honey SQL, plain clojure.java.jdbc, …)

“Specs” for re-frame application state db
It can be better to not enforce using spec for app-db because the additional value is not so high and it can lead to tedious updates of spec whenever you add something to app-db
Usefulness of namespaced keywords
avoid conflicts: same keywords in different namespaces
Pitfalls of debugging CLJS
unclear error messages
hard to find root cause
Logging
log whole Clojure data structure instead of standard log lines?
you can then process logs with clojure (search, filter, …)
Using Ansible for automatic deployment
figwheel-like experience on backend
Figwheel
re-load on save vs. reload explicitly (triggered by keyboard shortcut)
explicit reload gives us a better control
Ideas for next meetups
Applications / System showcases
demonstrate the apps we are working on
discussion, best practices
Coding dojo - we can work together on 4clojure problems or similar
Invite Pavel Tisnovsky to Brno Clojure meetup
I’m really looking forward to the next Brno Clojure meetup.
I’d be love to see more people there as well.
Since 2010, I’ve been interested in functional programming and non-Java JVM languages, most notably Scala & Groovy.
