Synopsis

Shell
codeql resolve extractor --language=<lang> <options>...

Description

[Deep plumbing] Determine the extractor pack to use for a given language.

Options

Primary Options

-l, --language=<lang>

[Mandatory] The name of the extractor to locate.

--search-path=<dir>[:<dir>...]

A list of directories under which extractor packs may be found. The directories can either be the extractor packs themselves or directories that contain extractors as immediate subdirectories.

If the path contains multiple directory trees, their order defines precedence between them: if the target language is matched in more than one of the directory trees, the one given first wins.

The extractors bundled with the CodeQL toolchain itself will always be found, but if you need to use separately distributed extractors you need to give this option (or, better yet, set up --search-path in a per-user configuration file).

(Note: On Windows the path separator is ;).

--just-check

Don't print any output, but exit with code 0 if the extractor is found, and code 1 otherwise.

--format=<fmt>

Select output format. Choices include:

text (default): Print the path to the found extractor pack to standard output.

json: Print the path to the found extractor pack as a JSON string.

betterjson: Print details about the found extractor pack as a JSON string.

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.
