The Banjo Programming Language is a redesign of C++ that adheres to that language's philosophy, semantics, and (largely) syntax.

Banjo has several external dependencies.

• CMake version 3.0 or greater. This provides the build system for Banjo.
• Boost version 1.55 or later.
• Lingo is a library that provides a number of utilities used by the compiler.
• LLVM is a highly portable and optimizable intermediate
  representation for programming languages.

Use the fork feature on github to fork the repo to your page.

Add the original repo to your upstream:

git remote add upstream https://github.com/asutton/banjo.git

Run

git remote -v

to make sure the upstream has been added.

To get the latest updates to Banjo:

git fetch upstream

To merge your local changes, checkout your local master and run:

git merge upstream/master

After cloning the repository (or a fork of the repository), go into the directory and run:

git submodule update --init --recursive

This will pull the required versions of Lingo into your working directory.

Note that if you have a fork of Banjo, you may occasionally need to update the 'lingo' submodule. That can be done using the following command:

git submodule update --remote --merge

The build is configured by CMake. Within your clone of the Banjo repository, run the following commands to establish the build system in the build directory.

mkdir build
cd build
cmake ..

It is generally useful to build in debug mode. You can run ccmake to edit the build configuration.

ccmake ..

Set the value of CMAKE_BUILD_TYPE to Debug. Capitalization matters.

Now you can build the compiler:

make

You can run the test suite by running:

make test

If you want to test the parser, you can use the test_parse program. It takes the name of a single input file as an argument and prints information about the parsed program (or errors).

./banjo/test_parse input.banjo

When lowering LLVM to native assembly on new versions of Mac OS X you may need to override the system triple to avoid linker warnings. Invoke llc like this:

llc -mtriple=x86_64-apple-macosx <input>
