This is the C2 compiler written in C2 itself.

C2 is an evolution of C, please see http://c2lang.org for more info.

The first version was written in C++ and can be found at (https://github.com/c2lang/c2compiler)

This version does not support all the test cases yet, but is catching up fast

see the installation document for installation on Linux or OSX.

Since c2c is written in C2, a bootstrap is needed. Please run

make -C bootstrap

This will create a boostrap c2c version and use it to build the c2c compiler. The output will be in the folder output/

Now you can run the regular compiler to compiler (other) C2 projects

./output/c2c/c2c

The C2 compiler has a plugin system, that allows plugins to be loaded during compilation and the AST to be modified by them.

c2c will look for plugins in the environment variable $C2_PLUGINDIR (set by the env.sh script). Also the path can be set in the build-file. To install the plugins initially, run ./install_plugins.sh. This will create ~/c2_plugins/ and copy all plugins there.

To run c2c without plugins, use --noplugins.
