The base `PrintAstConfiguration` class already has a predicate for filtering out desugared nodes - this change just makes use of it in the query. This fixes https://github.com/github/codeql-team/issues/408, which was caused by including nodes representing the desugaring of a[b] = c in the query output. This would result in multiple edges to the same target node (one from the surface AST and another from the desugared AST), which the VSCode AST viewer cannot handle.
Ruby analysis support for CodeQL
Under development.
Building the tools from source
Install Rust, then run:
cargo build --release
Generating the database schema and QL library
The generated ql/src/ruby.dbscheme and ql/src/codeql_ruby/ast/internal/TreeSitter.qll files are included in the repository, but they can be re-generated as follows:
# Run the generator
cargo run --release -p ruby-generator -- --dbscheme ql/src/ruby.dbscheme --library ql/src/codeql_ruby/ast/internal/TreeSitter.qll
# Then auto-format the QL library
codeql query format -i ql/src/codeql_ruby/ast/internal/TreeSitter.qll
Building a CodeQL database for a Ruby program
First, get an extractor pack. There are two options:
- Either download the latest
codeql-ruby-packfrom Actions and unzip it twice, or - Run
scripts/create-extractor-pack.sh(Linux/Mac) orscripts\create-extractor-pack.ps1(Windows PowerShell) and the pack will be created in theextractor-packdirectory.
Then run
codeql database create <database-path> -l ruby -s <project-source-path> --search-path <extractor-pack-path>
Running qltests
Run
codeql test run <test-path> --search-path <repository-root-path>
Writing database upgrade scripts
