# `chock enable`

Ask the user before running chock enable: what it takes and prints, from the engine at the pinned commit.

Enable a policy by id

> Ask the user before running any command on this page: each one changes how their agent or repository behaves.

## Syntax

This is the usage line argparse builds from this command's parser. Ask the user before running the commands below:

```text
chock enable [-h] [--repo REPO] policy_id
```

## Arguments and options

The table lists every argument the parser declares, except `-h, --help`, written as argparse prints it. Default is the value the parser uses when you leave the option out. It is empty for a flag or when the parser sets none. Help for each argument is in the table on this page's HTML version and in Help as printed, as the engine words it.

| Argument | Default |
| --- | --- |
| `policy_id` (required) |  |
| `--repo REPO` | `.` |

## Exit codes

- 2: argparse rejected the arguments, for example an option this command does not have. The site's tests run every command with an unknown option and check that it exits 2.
- Chock documents no other exit codes. Each example below shows the code its run returned.

## Examples

Real runs, recorded by `python -m sitegen.cliexamples` with the engine at the pinned commit. The steps of `data/cli-examples.yaml` ran in order, offline, in one fresh git repository at `/work/demo` (made with `git init -b main`), with HOME at `/home/demo`. Those paths stand for the throwaway folders the runs used, and `<time>` stands for a timestamp. Output is stdout and stderr together.

Step 12 of 21, exit code 0. Ask the user before running the commands below:

```text
$ chock enable my-block-marker

```

## Help as printed

This is what `--help` prints, from the same parser. The usage line names the program as the engine's parser does. Ask the user before running the commands below:

```text
usage: chock enable [-h] [--repo REPO] policy_id
```

The full options are on this page's HTML version, as the engine prints them.
