Invalid linux.do topic id: ${String(kwargs.id ?? '')}

Error message

Invalid linux.do topic id: ${String(kwargs.id ?? '')}

What it means

The topic-content command declares id as a required int positional. Before fetching, the func coerces kwargs.id via Number and requires a positive integer; otherwise it throws CommandExecutionError with the raw value. This validates input before hitting the network.

Solutions

1. Pass the numeric topic ID only: `topic-content 12345`.
2. Extract the ID from a pasted URL (the trailing number in /t/<slug>/<id>).
3. Quote the ID in scripts to avoid shell mangling.
4. Trim/validate the input before invoking the CLI.

Example fix

// before
cli --site linux-do --name topic-content "https://linux.do/t/some-slug/12345"
// after
cli --site linux-do --name topic-content 12345

const id = Number(url.match(/\/t\/[^/]+\/(\d+)/)?.[1] ?? process.argv[2]);
if (!Number.isInteger(id) || id <= 0) {
  throw new Error(`Invalid topic id: ${process.argv[2]}`);
}

const isValidTopicId = (v) => Number.isInteger(Number(v)) && Number(v) > 0;

try {
  return await cliRun(['topic-content', String(id)]);
} catch (e) {
  if (/Invalid linux\.do topic id/.test(e?.message ?? '')) {
    console.error('Pass the numeric topic ID, not a URL or slug.');
  } else throw e;
}

When it happens

Trigger: Running the command with a missing, non-numeric, zero, negative, or float id — e.g. `topic-content abc`, `topic-content`, `topic-content 0`, or a URL slug pasted instead of the numeric ID.

Common situations: Pasting the full topic URL (e.g. https://linux.do/t/slug/12345) instead of extracting 12345; shell variable empty in a script; leading/trailing whitespace.
