sas-lexer

https://github.com/mes-amis/sas-lexer-rb

A Ruby FFI binding to the `sas-lexer` Rust crate by Misha Perlov (https://github.com/mishamsk/sas-lexer). Tokenizes SAS source code into a stream of typed tokens with full position metadata. Ships prebuilt native libraries for supported platforms; a runtime FFI loader picks the matching one for the host.
