Hi all,
TXR 175 is out; binaries at Bintray.
This is a significant release which brings in a foreign function interface (FFI).
TXR programs can now call libraries through C API's. Lisp functions can be used as callbacks.
It's possible to create bindings to all sorts of middleware without compiling any C code or modifying the TXR executable: graphical interfaces, databases, machine learning, audio-video media, numerical code, you name it.
Not to be overlooked are about half a dozen other feature enhancements and fifteen or so bugfixes. There have been nearly 150 new commits since 174.
Cheers ...
