## Exploring REPL tooling with socket prepl

A peek under the hood of how Clojure tools connect to the REPL followed by a deeper dive into how prepl works and what I've learned from implementing almost IDE like tools with it.

Starting with a brief discussion of nREPL, a network REPL that provides a server and client, common APIs for tooling and other tools to evaluate Clojure code in remote environments. We will show that CIDER / nREPL is based around middleware, with the ethos that the tool and middleware are one cohesive thing.

The main talk will be a dive into what a socket prepl is and how it works. I'll be sharing my opinions and ideas about these different tooling foundations through my Neovim plugin project, Conjure https://github.com/Olical/conjure.

Comparing socket prepl to nREPL I'll show that it can be just as powerful even without middleware support. I'll also use figwheel and prepl together to show practical ClojureScript uses. The ClojureScript prepl is almost the same but has a few pitfalls (mainly for other tool authors).

Then onto building tools on top of prepl, tools which I use day to day at work on the same projects as my colleagues but without any tool specific dependencies.

Wrapping up with a Q&A on tools, the foundations they're built on and different methodologies of REPL tooling.

Our monthly gatherings are often varied, from talks to workshops to public speaking training and many things in between. They are a chance for anyone in the community to share their experiences.

We have talks from well-known speakers in the Clojure/Script community and support and encourage those new to public speaking to share their experiences. Everyone has a different journey in life, so we all have something to share

We also have workshops at our gatherings and we can book a room with desks and power for everyone to work on. Past workshops include Transducers, ClojureScript games, and Spacemacs for Clojure development.

Our gatherings are typically on the first Tuesday of each month (except December when we have our annual ClojureX conference.

Thank you
