This is my fork of the Joy programming language.
There are no required external dependencies. To build the interpreter
with a basic garbage collector, run make, or make debug for a
debug build.
Optionally, to build the interpreter with the Boehm-Demers-Weiser garbage collector, first install the library with your package manager, or fetch the source and build it yourself.
It is important to install the latest development version of BDW on OS
X. The latest development version, currently 7.5.0, includes proper
support for detecting __alloc_size__ when compiling with clang.
brew install bdw-gc --HEAD
apt-get install libgc-dev
Note: Makefile needs to be updated to have generic include paths.
The interpreter can be used in two ways.
To load and interpret a program, pass the program file as the only argument:
rjc your-program.joy
To start a REPL, pass in zero arguments:
rjc
If the current directory contains the file usrlib.joy, the
interpretor will load it before running your program or starting the
REPL. (A file with this name exists in the project's lib directory.)
