V (DJMcMayhem)

V is a 2D string-based golfing language designed by DJMcMayhem. It is an extension of the Vim text editor that provides many mappings to common vim-golf idioms, as well as providing new features not implemented in vim, such as compressed regular expressions, extended recording/macro abilities, new operators, and more convenient ways of taking input/output and running programs.

The official interpreter is found on Github, and an online interpreter is hosted at https://tio.run/nexus/v thanks to PPCG user/moderator Dennis.
