Implementation of the ex/vi text editor

Nvi is an implementation of the ex/vi text editor originally distributed as part of the Fourth Berkeley Software Distribution (4BSD), by UC-Berkeley. Nvi supports all the historic ex/vi features except for open mode and the lisp edit option (e.g., it has a fully implemented underlying ex mode). It has a number of additional features as well:

  • 8-bit clean data, lines and files limited by available memory
  • Multiple edit buffers
  • Colon command-line editing and path name completion
  • Tag stacks (including support for Cscope databases)
  • Extended Regular Expressions
  • Infinite undo
  • Horizontal scrolling
  • Message catalogs (Dutch, English, French, German, Russian, Spanish, Swedish)
  • Preliminary support for Perl and Tcl/Tk scripting languages
