Ask HN: Looking for a code-first alternative to Obsidian/Notion

Hi, I like to store documentation, notes and research documents for many of my personal projects. At the moment I'm using Obsidian/Notion, but (at least to my knowledge) they lack the ability to easily embed and reference parts of the codebase.

So I'm looking for a tool/plugin that allows me to treat both documentation and code as first-class citizens in the app.

Ideal requirements: - Be able to edit documentation/code in the same app without losing too much editing functionality (while a LSP is good, I'd be satisfied with basic syntax highlighting) - Be able to reference files, folders and parts of code as links in my documentation - Have everything be saved as physical files on disk (something Notion doesnt really support)

Does anyone know of something similar? Thanks
