My Improved Vi

My Improved Vi

Since original vi editor is quite limited, there's need for improved version of it.

Yet popular and fairly good alternative is Vim but some might say it has too much features, and has it's own limitations. There's some tries to modernize it, such as Neovim, but for my opinion they just make some things too compliated.

My Improved Vi - or MIV - is totally new implementation of Vi kind of editor. It should be modern, written with modern C++ and targeted for modern systems (latest Linux distributions). It should work great with my current Vim workflows, and support most of the useful features.

Or to start editing a file:

src/miv ../src/buffer.cpp
