createInterface from node:readline starts requiring --allow-env=TERM in Deno v2.3

[imcotton]

Version: Deno 2.3.x

sample code:

import { Readable } from 'node:stream';
import { createInterface } from 'node:readline';

const input = Readable.from(`
    l1
    l2
    l3
`);

const stream = createInterface({ input });

const lines = await Array.fromAsync(stream, str => str.trim());

console.log(lines.filter(Boolean));

This is expected and caused by #28280 - before Deno v2.3.0, Node and npm packages silently ignored when an env var was not available which led to inconsistent behavior.

That said, we might want to add TERM env var to a list of env vars allowed by default.

Good to know the reasoning behind the issue, and I think it would be improved experience to put the TERM in allowed by default 👍

Besides from result from CI running, on Mac OS 15.3.2 (M4 mini) I find the require of TERM also present before Deno v2.3.x, I couldn't recall which version I have tested, but this seems not the case back in Deno v1 at some point?
