mvi

Minimal vi-like text editor in ~500 SLOC.

mvi is less advanced than svi.

Commands

:d        - delete line
:q        - quit
:q!       - force quit
:w [file] - write to file
h,j,k,l   - left, down, up, right
i         - insert mode
ESC       - normal mode

Dependencies

• ncursesw (or ansicurses with -lansicurses and #include <ansicurses.h>)
• libutf (another compatible libutf here)

Description

The editor is very minimal, so few commands are supported. Search, substitute, etc, should rather be in a fork.

mvi is fully functional.

Some issues

Hello,

Congrats for your work, that's exactly what I was looking for.

I need to allow users to edit a file without being able to edit something else than the file I passed as parameter.

vim has a lot of ways to do that (:e :w ) plus all restrictions can be bypassed.

With mvi it's not possible to escape to shell also that's good :)

I notice two issues though:

crontab -l | mvi -

doesn't work as characters are printed in a loop after output of the result of the command before the pipe. It's easy to use a temporary file though.

There's no replace (r and/or R in vim) and it is only possible to insert, you cannot delete a character, that's definitely missing.
