Calling #Psion and other #RetroComputing and #VintageComputing #PDA enthusiasts: doing an article about an OPL language server, and was hoping to get comment from someone who still writes OPL in the year 2025 - why, what do you use it for, would you find OPL autocomplete a help or a hindrance during development?

Ta!

@ghalfacree Hi Gareth! I'm an active user of OPL - in fact, I'm currently developing a language server to make programming in OPL a bit easier in modern IDEs. I previously created an OPL syntax highlighting extension for VS Code (https://github.com/colinhoad/psion-opl-syntax-highlighting) and this is my active work-in-progress language server project (https://github.com/colinhoad/psion-opl-language-server).

@colinhoad You're not going to believe this... but the article I'm writing is literally about your OPL language server! I've just sent you an email via your webform - didn't know you were on here!
