At work, I collaborate with people using different setup and different programming languages. And it can be tedious or time-consuming to manage all that, for each; context switching, etc. Therefore, most of the times, we ends with: an editor (whatever which one) and a terminal running some “REPL“. For sure, it is better if $editor and $repl are able to communicate back and forth. However, most of the time, the pleasant experience comes first from the $repl capacities. Emacs + Geiser is often a way to have better $repl capacities than what Guile offers by default. For example, IPython, GHCi, R, Julia, etc. provides all a better experience by default: completion, quick access to documentation, etc. For what it is worth – not much! :-), let trivially compare below, in order to get a feeling about one basic capacities. Well, I think the “poor” experience programming with Guile without using Emacs mainly comes from the lack of Guile REPL features by default. My 2 cents. :-) Cheers, simon --8<---------------cut here---------------start------------->8--- $ guix shell --pure guile -- guile -q GNU Guile 3.0.9 Copyright (C) 1995-2023 Free Software Foundation, Inc.
