Yogthos c91b6092bc ffi: foreign-callable — receive callbacks from C ... jolt could call C (foreign-fn -> foreign-procedure) but C could not call back into jolt, which GTK signals (and any callback-taking C API) require. Add the inverse: jolt.ffi/foreign-callable wraps a jolt fn as a C-callable function pointer, mirroring the foreign-fn pipeline. A new jolt.ffi/__ccallable special form carries the fn as a child expression (analyzed + walked by the passes; ir.clj gains an :ffi-callable arm in both child walks) plus literal arg/ret type keywords. The back end lowers it to a locked Chez foreign-callable and returns its entry-point address as a jolt pointer; host/chez/ffi.ss registers the code object so the collector keeps it, and free-callable unlocks it. :collect-safe emits the convention that reactivates the thread on entry, for callbacks fired while it is parked in a :blocking call (a GTK main loop). Test: ffi-binding-test.ss sorts an int array through libc qsort with a jolt comparator (C -> jolt -> C). Re-minted seed.		2026-06-23 09:55:17 -04:00
