Hi all,
I'm subscribed to the $ 20 plan of ChatGPT, for personal use and sometimes for work. At home I use it mostly for a side project. I transcribed the PL/0 compiler source from Wirth's 1976 book "A+DS=P" and modified it to run with current FPC. Then I started to add features one after another, to make it a subset of Pascal able enough to compile itself. I'm not there yet, but getting closer.
The most remarkable thing here is that my coding sessions are roughly 15 to 20 minutes, as I have a full time job, a wife and three children, and take care of some family real state, so this is the only way that project could possibly go forward. In fact, I've been dreaming of doing something like that for a few years now.
My setup is Linux Mint latest with FPC and VS Code with Codex extension. The process is very conservative I think, I ask for suggestions, then discuss the answers, and try to go forward in controlled and reviewed patches. I don't dare doing this fancy new agentic thing, at least yet, as I have seen a fair amount of "I asked this and you did that" to trust the whole process on agent Smith.
Hope this helps,
Daniel
