Wasite

Wasite is the WASI Terminal Environment API standard. It defines a set of environment variables and stdin/stdout parsing rules for interfacing with a generic terminal. It is not developed by the same people as WASI, and may conflict with WASI’s future goals (future WASI features may deprecate Wasite features). Wasite’s only purpose is to extend WASI to make it possible to write interactive terminal applications using WASI today.

Wasite aims to stay as close as possible to what you might expect to find on a standard POSIX-like terminal for environment variables and parsing of stdin and stdout. Wasite uses a subset of the ANSI escape sequences.

This document is the official specification for Wasite.
