uses process

Before a command: a mirror's files changed outside tcm (by hand, a git pull or checkout) are imported first, so the command sees them. Files that don't import yet (an edit half made) wait, and so does writing back to them. What it says goes to stderr: a command's output is its own.

import { dim } from "#codebase/tcmts/cli/style";

export function followMirror(cb: Codebase) {
  const m = loadMirror(cb);
  // (a session on another branch doesn't take the files' changes: they're the mirror's branch's)
  const changed = m && onMirrorBranch(cb, m) ? changedFiles(m) : [];
  if (!m || !changed.length) return;
  const log = console.log;
  const write = process.stdout.write;
  console.log = console.error;
