I try everywhere I can to install an Emacs mode for code/text navigation. But they tend to be inconsistent and for some software, it is simply not possible.
Do you have good resources to help there (running Linux/Gnome)? Do you keep the faith or switched "out"?
I also use this plugin https://github.com/minad/consult which has the command `consult-ripgrep`, very useful for e.g. looking up all occurrences of the symbol at point (and text navigation across multiple files).
For "AI", start with https://github.com/karthink/gptel/ (its README lists alternative packages, as you can see there is no lack of llm support in emacs, both chat, "agents" and more specific use-cases)
Also, on the llm point even though I know elisp, and use emacs heavily, they can be great for creating little personal commands that just make things a little nicer to use (lowering the barrier of "I'll write a command for this" from 15 minutes to 2 minutes is huge and means I can be bothered to do it for more marginal things which makes the editor even more pleasant to use).
I think that the AI CLI agents are the response for AI, but for now, I am opening VSCode with an Emacs extension and some keybinding changes.
