CodeQL scripts for extracting measurement data from C, C++, Python and Java projects.

Running these scripts requires installing the command line version of CodeQL and Java (to execute the CodeQL jar).

CodeQL works on project databases, which can be built using CodeQL.

The CodeQL extension in Visual Studio Code can download project databases from GitHub.

The command codeql.sh proj_db feature.ql runs the CodeQL script +feature.ql+ on the contents of the database +proj_db+ to produce a csv file in the +csv+ directory.

This script invoke +codeql+ twice, once to create a bqrs file (an intermediate file used by CodeQL), from which the csv file is then generated.
