Hey @aviatesk and @pfitzseb ! Just little FYI that Pluto will only use the REPL stdlib for future version, dropping the FuzzyCompletions dependency.

Pluto mostly stopped using FuzzyCompletions.jl for fuzzy completions around 2023, we now do this one the front-end (JS) with https://github.com/codemirror/autocomplete instead. But I never wrote the full refactor to factor out FuzzyCompletions.

Because of these 1.12 issues (and same for previous Julia versions), I thought the easiest path forward is to complete this refactor, and only use the REPLCompletions stdlib, without FuzzyCompletions.jl fonsp/Pluto.jl#3207 So future Pluto versions will not use FuzzyCompletions.jl, but get the full list of fields/paths/whatever from REPLCompletions and fuzzy-search on the frontend.

I hope you don't feel offended by the change! We really appreciated using FuzzyCompletions.jl so far, and Pluto's users benefited from it a lot :) I'm doing this because I am a bit overwhelmed by the amount of work we need to do for each Julia release, so I am trying to use as little internal Julia API as possible (and move things to JS when possible).
