Embedded schema interpreter

I know that Lua is best in class for embedding, but I want to use Scheme or some LISP dialect as the scripting language for my C application. What are good translators for embedding? My criteria:

  • Open source (preferably in C - I think most of them).
  • R5RS is very welcome, SRFIs plus.
  • Easy FFI with C (in both directions) is very important.
  • Must be saved, updated, not dead projects.
  • Performance comparable to Lua.
  • Portable (at least GNU / Linux - MacOS - Windows (MinGW / Cygwin is acceptable)).

I do not care:

  • Large library (with simple FFI, I can add a missing one), but that's a plus.
  • The size. I plan to run it on a desktop computer, not on Android / iOS.
  • Rich documentation. Some samples with FFI may be sufficient.

I currently consider the following:

  • GNU Guile This seems to fit, but I don't know about performance (is it VM or interpreted?).
  • newLISP. Brand new, documented, but not sure about performance and embedding.
  • TinyScheme / Chibi. Very small, R5RS, designed for installation. Not sure about performance.

You should consider Chicken Scheme :

  • Native support for cross-compiling applications for embedded purposes

And it meets your criteria, take a look at the list of functions on the linked page.
