codeql database print-baseline <options>... -- <database>


[Plumbing] Print a summary of the baseline lines of code seen.

This command will print to standard out the baseline lines of code seen within the source root specified at codeql database init time for each language present in the database.

The baseline is an estimate of the non-empty, non-comment lines of code in a database. This count is different from the lines of code counted by CodeQL metrics queries, which only counts code that is passed to the CodeQL evaluator. In some cases, the baseline count may be lower than the count in metrics queries since metrics queries may include external files that are passed to the evaluator, but are not included in the source root.


Primary Options


[Mandatory] Path to the CodeQL database under construction. This must have been prepared for extraction with codeql database init.

If the --db-cluster option is given, this is not a database itself, but a directory that contains databases, and all of those databases will be processed together.


Indicates that the directory given on the command line is not a database itself, but a directory that contains one or more databases under construction. Those databases will be processed together.

Common options

-h, --help

Show this help text.


[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.


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


[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.)


[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.
