beaker

The Beaker Programming Language.

Dependencies

Beaker has several external dependencies.

• boost 1.55 or higher.
• asutton/lingo is a library that provides a number of utilities that can be used within various compilers. This
• The csll/llvm library provides a lightweight text-based LLVM assembly generator.

Note that Beaker does not depend on LLVM directly because the LLVM flags disable exceptions, which beaker relies upon heavily.

Building Beaker

After cloning the repository, go into the directory and run:

git submodule update --init --recursive

This will pull the required versions of asutton/lingo and csll/llvm into your working directory.

Note that if you have a fork of beaker, you will need to update lingo submodule.

git submodule update --remote --merge

The build is configured by CMake.

mkdir build
cd build
cmake ..
make

Running the compiler

The compiler is run by the command beaker. It takes a single input file as an argument:

./beaker input.bkr

If input.bkr has a function named main, that function is evaluated (main must not take arguments). Otherwise, the compiler simply prints no main.

Testing

There is a test directory within hbe

Notes

The beaker implementation does not (currently) directly depend on lingo. Eventually, beaker will depend on the following features in lingo:

• string formatting
• node concepts
• debugging macros
• sexpr debugging

The long-term plan is to migrate a number of features out of beaker and into lingo, replacing older, less capable implementaitons. These are likely to be:

• the symbol table
• input buffer
• tokens
• lexing and parsing
• generic environments
• ???
