 Open source Vim-like text editor

 Author:   Marc André Tanner

"Vis aims to be a modern, legacy free, simple yet efficient editor combining the strengths of both vi(m) and sam.

It extends vi's modal editing with built-in support for multiple cursors/selections and combines it with sam's structural regular expression based command language.

As an universal editor it has decent Unicode support (including double width and combining characters) and should cope with arbitrary files including:

    large (up to a few Gigabytes) ones including
    Wikipedia/OpenStreetMap?? XML / SQL / CSV dumps
    amalgamated source trees (e.g. SQLite)
    single line ones e.g. minified JavaScript
    binary ones e.g. ELF files

Efficient syntax highlighting is provided using Parsing Expression Grammars which can be conveniently expressed using Lua in the form of LPeg.

The editor core is written in a reasonable amount of clean (your mileage may vary), modern and legacy free C code enabling it to run in resource constrained environments. The implementation should be easy to hack on and encourage experimentation. There also exists a Lua API for in process extensions.

Vis strives to be simple and focuses on its core task: efficient text management. As an example the file open dialog is provided by an independent utility. There exist plans to use a client/server architecture, delegating window management to your windowing system or favorite terminal multiplexer.

The intention is not to be bug for bug compatible with vi(m), instead we aim to provide more powerful editing features based on an elegant design and clean implementation."
