Semgrep Product Update

Feb 7, 2024

Update Semgrep Code

Support for anonymous metavariables (rule-writing and syntax)

You can now use anonymous metavariables when writing or customizing rules, which have the form $_. These metavariables do not bind in the environment, meaning they also do not unify. As such, patterns like:

foo($_, $_)

can match code like

foo(1, 2)

Happy rule writing!
