heirloom-ex-vi's Introduction

The traditional Vi

This implementation had been derived by Gunnar Ritter from ex/vi 3.7 of 6/7/85 and the BSD termcap library, originally from the 2.11BSD distribution. He had added some useful enhancements, most notably UTF-8 support.

The last release of heirloom-ex-vi had been version 050325 (4.0). Until 2007 he added new features, e.g. dynamically allocated screen buffers for resizing the terminal and support for files with arbitrary line length.

These changes did introduce an issue to numbered lines mode. This and other found bugs are fixed now. A simple ./configure had been added to set curses as the terminal capabilities access library on some systems.

How to install

The embedded termcap library may cause problems on systems where there is no /etc/termcap and $TERMCAP of the user that runs ./configure and other users (e.g. root) differs. Therefore using termcap has lowest priority during auto-configure. To prefere termcap put the corresponding line before the curses entries in configure.

$ ./configure
$ make
$ su
# make install
# exit
$ make mrproper

Usage information

The traditional vi reads the file ~/.exrc at start-up. For full screen scrolling vi uses the keys ^F and ^B. To make <PAGE-DOWN> and <PAGE-UP> work add the following lines to .exrc:

map ^[[5~ ^B
map ^[[6~ ^F
