Vis a vim-like text editor
Vis aims to be a modern, legacy free, simple yet efficient editor combining the strengths of both vi(m) and sam.
As an universal editor it has decent Unicode support and should cope with arbitrary files including: large, binary or single-line ones.
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. Clipboard and digraph handling as well as a fuzzy file open dialog are all provided by independent utilities. 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.
- curses (recommended)
- Lua >= 5.2 (optional)
- LPeg >= 0.12 (optional runtime dependency required for syntax highlighting)
- TRE (optional for more memory efficient regex search)
Assuming these dependencies are met, execute:
$ ./configure && make && sudo make install
By default the
configure script will try to auto detect support for
configure --help for a list of supported options. You can
also manually tweak the generated
Or simply use one of the distribution provided packages.
Some features which will not be implemented:
- tabs / multiple workspaces / advanced window management
- file and directory browser
- support for file archives (tar, zip, ...)
- support for network protocols (ftp, http, ssh ...)
- GUIs (neither x11, motif, gtk, win32 ...) although the codebase should make it easy to add them
- right-to-left text
- ex mode, we have more elegant structural regexp
- diff mode
- internal spell checker
- lots of compile time configurable features /
