Inspiration
BetterThanVim (BTV) is deeply inspired by the infamous Unix standard editor (ed).
What it does
BTV is a command-based command line text editor, rather than a visual text editor. You can specifics on the commands here and see a demonstration in the video above.
When you open or create a file using BTV, you are prompted for commands. You can use commands like a, A, e to insert or edit the file, commands like <n>, +, -, ^, $ to navigate, r to figure out where you are, . or .<n> to figure out what you're looking at, y to yank (copy), x to cut, p or P to paste, w to save and q to quit.
How I built it
I programmed it in Rust, mainly using the standard library and a few crates.
Challenges I ran into
I have never created a program in Rust until now, and I came in mostly blind to using it. Rust is probably the most difficult systems language to learn; it's far much more difficult/complex than C, although it is safer when it comes to memory allocation/management.
Accomplishments that I'm proud of
Completing this program in Rust without giving up and rewriting the whole thing in C.
What I learned
Mainly Rust knowledge, and also ed knowledge.
What's next for BetterThanVim
More commands. 18 is hardly enough. Also needs some internal cleanup.
Built With
- cargo
