About specifying command options in a CodeQL configuration file
You can save default or frequently used options for your commands in a per-user configuration file.
You can specify CodeQL CLI command options in two ways:
- Directly in the command line, using the appropriate flag.
- In a configuration (or
config) file that CodeQL scans for relevant options each time a command is executed.
For options that are likely to change each time you execute a command, specifying the value on the command line is the most convenient way of passing the information to CodeQL. Saving options in a config file is a good way to specify options you use frequently. It’s also a good way to add custom CodeQL packs that you use regularly to your search path.
Using a CodeQL configuration file
You need to save the config file under your home (Linux and macOS) or user profile (Windows) directory in the .config/codeql/ subdirectory. For example, $HOME/.config/codeql/config.
The syntax for specifying options is as follows:
<command> <subcommand> <option> <value>
To apply the same options to more than one command you can:
- Omit the
<subcommand>, which will specify the option for every<subcommand>to which it’s relevant. - Omit both
<command>and<subcommand>, which will globally specify the option for every<command>and<subcommand>to which it’s relevant.
Notes:
configfiles only accept spaces between between option flags and values—CodeQL will throw an error if you use=to specify an option value.- If you specify an option in the command line, this overrides the
configvalue defined for that option. - If you want to specify more than one option for a
<command>,<subcommand>or globally, use one line per option.
Examples
-
To output all analysis results generated by
codeql database analyzeas CSV format, you would specify:database analyze --format csvHere, you have to specify the command and subcommand to prevent any of the low-level commands that are executed during
database analyzebeing passed the same--formatoption. -
To define the RAM (4096 MB) and number of threads (4) to use when running CodeQL commands, specify the following, on separate lines:
--ram 4096 --threads 4 -
To globally specify a directory for CodeQL to scan for CodeQL packs (which is not a sibling of the installation directory), use:
--search-path <path-to-directory>
