C3 v0.1.3

C3 is a programming language with meta-programmation and a graph database embedded into the language. It aims to be the language for semantic programming, and programming the semantic web.

We are currently fundraising for the project to become real and there is a working prototype available at https://git.kmx.io/c3-lang/c3/, please see the https://www.kmx.io/en/donations.html page for helping out.

C3 is currently a programming language project, inspired by C, Elixir and Common Lisp. It could be described as C with Elixir modules, pattern matching, and a semantic object system. The idea is to plug modules, closures, pattern matching, a graph database and metaprogramming into C99 with an extremely small set of dependencies.

Usage

Compilation

git clone https://git.kmx.io/c3-lang/c3.git
cd c3
git submodule init
git submodule update
./configure
make

Running the tests

make test
make test_asan

Running gdb

make gdb_test

Structure

libc3

C3 is implemented using libc3 a small C99 library implementing the core of the language.

The library includes a parser and an interpreter for C3 code in C structures.

Parser

The parser is recursive descent.

AST

The AST is represented as C3 data structures and can be meta-programmed in C.

Interpreter

Under development.

ic3

Interactive shell.

c3s

Script interpreter.
