dex — Capability Showcase

What this document shows. Three real queries against the dex codebase itself, run twice: once with no GPU or LLM services available, once with the full stack (embeddings + reranker + chat model). Every output below is grounded in the actual source files, field names, and line numbers of this repo.

The right way to override any highlighting if you don't want to edit the colorscheme file directly

Suppose you have weird taste and you absolutely want:

• your active statusline to always have a white background and red foreground,
• your very own deep blue background.

Your first reflex is probably to put those lines somewhere in your vimrc:

FWIW: I didn't produce the content presented here (the outline from Edmond Lau's book). I've just copy-pasted it from somewhere over the Internet, but I cannot remember what exactly the original source is. I was also not able to find the author's name, so I cannot give him/her the proper credits.
