## AI overview

A brief recommendation of Julia Evans's documentation of ANSI escape codes, noting their origins in VT100 terminal programming, later standardization, and widespread proprietary extensions.

## Source excerpt

I encountered the Escape sequences (named after the first character in the sequence) while programming stuff that would look nicely on the venerable VT100 terminals (not to mention writing one or two VT100 emulators myself). In the meantime, those sequences got standardized and (par for the course) extended with "proprietary" stuff everyone uses now. Julia Evans did a great job documenting the state of the art. Thanks a million!
