Lately I've spent too much time dealing with a bug involving having a precise JVM (GraalVM) running my REPL, here is the breakdown of how to know precisely - and change! - the current running JVM with Emacs and Cider.

First, you can inspect the command that will be used by Cider to start the clojure REPL with the universal-argument command. Run M-x universal-argument (SPC u with Doom Emacs) then cider-jack-in you could then edit the command before hitting ENTER to run the edited command.

In my case my project uses the Clojure CLI and deps.edn. You should see that cider use your clojure executable, on my machine /opt/homebrew/bin/clojure. If we inspect the clojure executable we see that one-liner:

From https://github.com/ESWAT/john-carmack-plan-archive/blob/master/by_day/johnc_plan_19981014.txt Layout - like bold - is my own.

It has been difficult to write .plan updates lately. Every time I start writing something, I realize that I'm not going to be able to cover it satisfactorily in the time I can spend on it. I have found that terse little comments either get misinterpreted, or I get deluged by email from people wanting me to expand upon it.

I wanted to do a .plan about my evolving thoughts on code quality and lessons learned through quake and quake 2, but in the interest of actually completing an update, I decided to focus on one change that was intended to just clean things up, but had a surprising number of positive side effects.

Since DOOM, our games have been defined with portability in mind. Porting to a new platform involves having a way to display output, and having the platform tell you about the various relevant inputs. **There are four principle inputs to a game: keystrokes, mouse moves
