A LISP in the spirit of Black and other colors.
Black is an extension of Scheme with a reflective construct exec-at-metalevel. It executes its argument at the metalevel where the interpreter that executes user programs is running. There, one can observe, access, and even modify the metalevel interpreter in any way. Because the metalevel interpreter determines the operational semantics of the language, Black effectively allows us to observe, access, and modify the language semantics from within the same language framework.
Replicated state machines are employed in a wide variety of applications requiring distributed coordination. Because RSMs must always adhere to particular semantic conditions, foremost determinism, rather than reprogram their semantics in every new instance, we propose a language, Radicle, which substantially simplifies the process of defining such state machines. As Radicle may be made into any RSM via eval-redefinition, it can be considered a universal replicated state machine. This mechanism also allows changing the semantics of running state machines without loss of state, and with the same consensus guarantees as provided by the underlying consensus system
Scheme 9 from Empty Space, Reimagined. S9fES is a mature, portable, and comprehensible interpreter for R4RS Scheme. The core interpreter is written in pure ANSI C (C89), so it runs on all platforms offering a C compiler. It can even be compiled natively on Plan 9. On Unix-based systems (or MinGW), it also offers an interface to common Unix system calls and Curses routines.
This is the keynote talk that I gave at the 2108 European Lisp Symposium in Marbella, Spain. Abstract: Lisp was invented 60 years ago. Coral Common Lisp, the ancestor of today's Clozure Common Lisp, was released over 30 years ago.
A micro-subset of scheme / the original LISP in a single C file: komplott.c
Interim OS is a radical new operating system with a focus on minimalism. It steals conceptually from Lisp machines (language-based kernel) and Plan 9 (everything is a file system). It boots to a JITting Lisp-like REPL and offers the programmer/user the system's resources as filesystems.
