CodeQL documentation

execute language-server

Synopsis

codeql execute language-server --check-errors=<checkErrors> <options>...

Description

[Plumbing] On-line support for the QL language in IDEs.

This command is only relevant for authors of QL language extensions for IDEs. It is started by the IDE extension in the background and communicates with it through a special protocol on its standard input and output streams.

Options

--check-errors=<checkErrors>

[Mandatory] How to check errors. One of: ON_CHANGE, EXPLICIT.

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

This works like the similar option to codeql query compile (q.v.).

There are no --additional-packs or --library-path options, as the corresponding values are provided online by the IDE extension through the language server protocol.

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

--synchronous

Carry out actions a single main thread rather than in a threaded executor.

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.)
