Otus Lisp (Ol in short) is a purely functional dialect of Lisp.

Otus Lisp language based on Scheme R⁷RS (PDF) with little changes and extensions.

Getting Started

Requirements

No special requirements are expected.

Ol should be easy to get up and run on most POSIX-compliant systems (such as Linux, macOS, Android, BSD's, webOS, Solaris, Minoca, PonyOS, etc.) and Windows (since ancient win95). All modern hardware architectures is supported (i686 and x86_64; armv5, v7, v8, and aarch64; ppc and ppc64, mips).

Ol interpreter/compiler, which can compile and run text scripts, requires 2MB of memory and 0.5MB of disk space for the binary itself. The Olvm (Ol virtual machine without interpreter/compiler), which can run only binary (precompiled) scripts, requires 20KB (Kilobytes, not a Megabytes) of memory for simplest scripts and less than 100KB for the binary itself.
