Show HN: LazyViewer – TUI code viewer with Git diff previews

Hi HN,

While I was coding with Codex I missed a tool that - like Cursor - shows diffs inline while it is able to do both tree navigation easily with keyboard and navigate the source code without changing mode (like in vim).

My favourite tool in TUI was lazygit, but I wanted a way to see the diffs inside the whole source code.

As this looked like a nice little project to vibe code in a few days, I did it and tried to perfect the integration of the few features that I wanted together: - Full easy keyboard + mouse navigation - Multiple tree support (unlike VS code / Cursor) - Inline diff - Ripgrep fast search - Sticky function/class headers

I tried tools like ranger and other navigators, and vim NeoTree preview, but none of these tools were really good for my use case.

Now what I got is an ugly code base in a super functional tool
