writeRepository

tcmts.dev.writeRepository · #5vqhev63 · term · runs on the server

uses node:fs

Write the files tcm's repository keeps (pnpm repository) as the codebase has them: what's in git is only how to get the codebase (its script, the agents' instructions, the README), and it's changed in the codebase like anything else. Says which changed; commit them by hand.

import { codebaseDir, repository, REPOSITORY_FILES, sh } from "#codebase/tcmts/dev";

import path from "node:path";

  const tcm = process.env.TCM_BIN;
  if (!tcm)
    throw new Error("run this with `tcm run`, which gives it the codebase's own tcm (TCM_BIN)");
  const repo = repository();
  const changed: string[] = [];
  for (const [name, rel] of Object.entries(REPOSITORY_FILES)) {
    const out = fs.mkdtempSync(path.join(os.tmpdir(), "tcm repository "));
    const r = sh(process.execPath, [tcm, "export", name, out], codebaseDir());
    const [written] = fs.readdirSync(out);
    if (!r.ok || !written) throw new Error(`tcm export ${name}: ${r.out.trim()}`);
    const content = fs.readFileSync(path.join(out, written));

      fs.writeFileSync(to, content, { mode: rel.endsWith(".sh") ? 0o755 : 0o644 });
