/'su.la/ for the suffix of capsule in Spanish, Cápsula.

A Gemini protocol server written in Scryer Prolog.

sula depends on a patched Scryer Prolog which can be found here (branch js/fixes). The required patches are:

A native '$copy_stream'/2 builtin used for streaming binary file bodies to TLS clients without materialising the contents on the Prolog heap.
A fix to library(pio)’s buffer_prepare_for_n/5 so that lazy reads from process pipes (and other streams whose at_end_of_stream/1 never reports true) terminate on EOF instead of spinning.
A non-blocking poll loop in socket_server_accept/4 that checks Scryer’s INTERRUPT flag, so SIGINT becomes a catchable '$interrupt_thrown' exception instead of being trapped behind a blocking syscall.
A port to rustls.
A modification of tls_server_negotiate to include the optional client certificate.
