## Synopsis

```shell copy
codeql generate extensible-predicate-metadata <options>... -- <pack-root-dir>
```

## Description

\[Deep plumbing] Report the extensible predicates found in the given
pack.

## Options

### Primary Options

#### `<pack-root-dir>`

\[Mandatory] The pack root directory for which we are reporting
extensible predicate metadata.

### Common options

#### `-h, --help`

Show this help text.

#### `-J=<opt>`

\[Advanced] Give option to the JVM running the command.

(Beware that options containing spaces will not be handled correctly.)

#### `-v, --verbose`

Incrementally increase the number of progress messages printed.

#### `-q, --quiet`

Incrementally decrease the number of progress messages printed.

#### `--verbosity=<level>`

\[Advanced] Explicitly set the verbosity level to one of errors,
warnings, progress, progress+, progress++, progress+++. Overrides `-v`
and `-q`.

#### `--logdir=<dir>`

\[Advanced] Write detailed logs to one or more files in the given
directory, with generated names that include timestamps and the name of
the running subcommand.

(To write a log file with a name you have full control over, instead
give `--log-to-stderr` and redirect stderr as desired.)

#### `--common-caches=<dir>`

\[Advanced] Controls the location of cached data on disk that will
persist between several runs of the CLI, such as downloaded QL packs and
compiled query plans. If not set explicitly, this defaults to a
directory named `.codeql` in the user's home directory; it will be
created if it doesn't already exist.

Available since `v2.15.2`.
