calame

Calame is a small thought-experiment machine to play and experiment reflexive and interactive systems.

It provides a small set of concepts to describe:

• a space,
• how it is observed,
• how it is internally transformed,

without prescribing any execution model, user interface or runtime.

Calame is intentionally small and stable and future works are expected to live in separate projects, or on top of it.

Core principle

At its core, Calame revolves a single structure: machine.ml

Machine
space : x
obs : x -> a
stab : x -> x

Example: small textual REPL

A small calame executable is shipped with the repository.

It implements a REPL over a Unicode text and a cursor using Calame's core abstractions.

Running the example

With opam and dune installed:

dune build
dune exec calame

Language-agnostic core

Although implemented in OCaml, Calame is language-agnostic by design.

The Ocaml codebase is a reference implementation of the model, not a mandatory dependency.

The same concepts can be reimplemented in other languages (e.g. C++, Rust) to build independent programs that share the same underlying model, that is a machine can be represented as observations of a space in movement (a dynamic space).
