Ritter's vi is derived from Joy+Horton vi. Illumos has the original.
- fragmede 4mo agoFascinating! I wonder what fork of vi I landed on that didn't have :x for me to have mis-picked-up that bit of trivia.
- JdeBP 4mo agoOnly Ritter vi is really a fork. All of the rest are clones, ground-up reimplementations not forked from the Joy+Horton code. Of them, and discounting the extreme fringes like vi-likes that run on the BBC Micro, only STEVIE lacks :x, and its derivatives all added it in. All of the other clones from MKS onwards, even neatvi and nextvi, have :x . * https://jdebp.uk/FGA/vi-family.html https://jdebp.uk/FGA/vi-family.html
