Lucid Energize Demo VHS 1993
Zach Beane

A 1993 VHS demo of Lucid Energize, a database-backed, incremental C/C++ programming environment built on XEmacs. It shows features like incremental compilation, live debugging and hyperlinked output.
HN cites it constantly as evidence that modern IDE and LSP-style features existed in the early 90s.
