Binary editor written in Go

I wanted to create a binary editor with Vim-like user interface, which runs in terminals, fast, and is portable.I have always been interested in various binary formats and I wanted to create my own editor to handle them.I also wanted to learn how a binary editor can handle large files and allow users to edit them interactively.

While creating this binary editor, I leaned a lot about programming in Go language.I spent a lot of time writing the core logic of buffer implementation of the editor.It was a great learning experience for me and a lot of fun.

brew install bed

go install github.com/itchyny/bed/cmd/bed@latest
