Classic Psion fan releases proof-of-concept language server for OPL

Vintage computing enthusiast Colin Hoad has released a gift to anyone who fondly remembers Psion's classic EPOC-based palmtops and their Open Programming Language (OPL): a language server which brings modern quality-of-life features to the OPL programmer, regardless of their development environment.

"OPL being a fairly old (I like to think 'venerable') language, there is scant support for it in any modern IDE, including [Microsoft] VS Code," Hoad writes in an introduction to the project ahead of its first public release.

"After some illuminating chats about this on the Psion Discord server, Alex Brown seeded the idea in my head of writing a language server for OPL using the now widely adopted Language Server Protocol (LSP). This felt like a meaty project I could really get my teeth into, and which would also serve as an opportunity to expand my own programming abilities."
