Lucee is now providing up-to-date json definitions of all functions (Full Lucee Docs for VSCode cfmleditor).
This has enabled me to make a nvim plugin that uses these definitions and provides them as a cmp completion-source. The plugin can be found here: oricat/cfcomplete.nvim: coldfusion completion source nvim-cmp - Codeberg.org
Contributions are highly welcome since due to my day-job I’ve not been able to divert too much time into this
