📝Text Editor in C++

The problem

Editors are one of the tools I rely on every day, but my mental model of them stopped at "there's a buffer somewhere." I wanted to fix that.

The approach

I'm building it incrementally — first a minimal terminal-mode editor with a gap buffer, then layering on richer features (undo stack, search, syntax highlighting). I keep the dependencies tiny so every layer of the stack is mine to understand.

Implementation highlights

• Gap-buffer-backed text storage with O(1) local edits.
• Custom input handling rather than relying on a UI framework.
• Profiling-driven; performance work is part of the project, not an afterthought.

Outcome & lessons

Still in flight. Ongoing notes from the project will land on the blog as I add features and run into interesting performance trade-offs.
