Function: degradeCapsFully() ​

degradeCapsFully(caps): CapabilityProfile

Defined in: host/width-probe.ts:353

Force a capability profile fully ASCII-safe: box-drawing and half-blocks off, ambiguous-wide on, so every chrome glyph maps to plain ASCII when rendered. This is the shape the host uses when JSVISION_ASCII is set. Pure.

Parameters ​

caps ​

CapabilityProfile

The capability profile to degrade.

Returns ​

CapabilityProfile

A new profile with all three glyph flags at their ASCII-safe setting.

Example ​

ts
import { resolveCapabilities, degradeCapsFully, serialize } from '@jsvision/core';

const caps = degradeCapsFully(resolveCapabilities().profile);
// serialize(frame, prev, { caps }) now emits ASCII box/scroll chrome.
