This is ex/vi descended from the original Bill Joy source as it was in
|
||
|
|
4.4BSD Unix.
|
||
|
|
|
||
|
|
Current BSD vi is actually nvi, a clean implementation derived from the
|
||
|
|
original Elvis code.
|
||
|
|
|
||
|
|
The original ex/vi code, even though it was written at Berkely, belonged
|
||
|
|
to AT&T at the time of the 4.4BSDlite release. It has subsequently been
|
||
|
|
released as open source at the time the Solaris source code was made
|
||
|
|
available.
|
||
|
|
|
||
|
|
The binary program derived from these sources is roughly half the size
|
||
|
|
of nvi and several orders of magnitude smaller than vim (don't get me
|
||
|
|
started on Emacs), while still being a tremendously useful and efficient
|
||
|
|
editor. It is still capable of being your daily driver, and should feel
|
||
|
|
immediately familiar to anyone who has spent time in nvi or vim.
