Claude in a terminal is becoming more and more my IDE. I use emacs to do some edits or to look at some files, but orders of magnitude less than when I wrote all the code.
Syntax highlighting? Yes, for readability. Completion? I noticed today that maybe I broke the language server for Ruby but I didn't bother to investigate. Maybe next week, or next month.
Git log, blame, diff, yes, as usual.
I don't see a bright future for IDEs. Vi or emacs from the 90s could be all we need.
Non developers using AIs to vibe code their projects maybe won't need any editor at all, nor an IDE.
I have found that I need more than this. A document viewer is critical so I can see HTML prototypes, review docs and other output and give feedback contextually inline (through a commenting system). I also need a task lists for my project/ agents so I can see where things are. I created an app like this for myself that is built around an integrated terminal, after I had the epiphany that VS Code (and VIM) were becoming the wrong tool because I am not actually spending time _writing_ the code.
What about search, and "find usages", and other affordances for navigating the codebase? I know vi can search within a file, but I think with larger codebases you need something more powerful.
vim buffers also work very well with agents
That’s exactly why Rune is also a terminal multiplexer. Rune acts as a bridge between automated and manual programming. You can fuzzy-search for symbols and files and reference them right from the chat UI, without having to copy and paste. When the agent is working, it uses Rune’s symbol index and IDE-grade toolset instead of greping the codebase. It also gets compilation errors right after applying patches.
And this is just the beginning. I think there’s so much more to explore in this space.
