This recognises barriers of the form
STRINGS = ["foo", "bar"]
case foo
when "some string literal"
foo
when *["other", "strings"]
foo
when *STRINGS
foo
end
where the reads of `foo` inside each `when` are guarded by the comparison
of `foo` with the string literals.
We don't yet recognise this construct:
case foo
when "foo", "bar"
foo
end
This is due to a limitation in the shared barrier guard logic.
Ruby analysis support for CodeQL
This directory contains the extractor, CodeQL libraries, and queries that power Ruby support in LGTM and the other CodeQL products that GitHub makes available to its customers worldwide.
It contains two major components:
- static analysis libraries and queries written in CodeQL that can be used to analyze such a database to find coding mistakes or security vulnerabilities.
- an extractor, written in Rust, that parses Ruby source code and converts it into a database that can be queried using CodeQL. See Developer information for information on building the extractor (you do not need to do this if you are only developing queries).
