Appearance

std/ansi ​

Cursor movement, screen control, and 256-color and 24-bit color escape codes: the lower-level primitives a full-screen terminal UI needs, next to std/color's named 16-color wrappers. Each function returns an escape string; build a frame in one buffer and write it once to avoid flicker.

milo
from "std/ansi" import { Ansi }

Example ​

milo
var frame = Ansi.clearScreen() + Ansi.cursorTo(1, 1)
frame += Ansi.fg256(208) + "status: ok" + Ansi.reset()
print(frame)
