Please see C2Lang.org for more info about C2!
The C2 project attempts to create a new language, strongly based on C. In a nutshell, the main differences with C are:
- no more header files (too much typing)
- no includes
- packages (needed if we can't have includes)
- compiled per target (not per file)
- more logical keywords (public/local replaces static)
- integrated build system
Below are the instructions for building and using the C2Compiler.
Have fun! (and code..)
C2 is based on LLVM 3.6 and some parts of Clang 3.6. The design of C2C's C2Parser and C2Sema class are heavily based on clang's Parser and Sema class, so hereby my thanks to the Clang folks!
What needs to be done
A short list of open items (the full list would probably fill-up GitHub) with their priority:
- [high] c2c: parse full syntax into AST
- [high] c2c: generate IR code for more AST elements
- [medium] c2c: improve C generation by generating forward declarations in C code.
- [medium] c2c: tab completion on targets in recipe / cmdline args
- [medium] tool: c2grep - grep only files in recipe
- [medium] tool: create c-parser for parsing C headers.
- [medium] tool: create c2style - astyle for C2.
- [low] c2tags/c2scope - only add files in recipe
Read the installation document.
Using the C2 compiler
By default, c2c will only parse and analyse the targets. Generating C-code should work on all examples, but generating LLVM's IR code is work in progress. In the examples directory: (or add -d examples/)
c2c multi c2c hello c2c iter c2c switch c2c working_ir
It's also possible to manually compile a single .c2 file without a recipe file with:
c2c -f <file.c2>
To generate ANSI-C code, use:
c2c -C <target>
The C2 compiler is able to generate a package dependency file in dot format. This file can be converted into a png as follows:
c2c --deps <target> dot -T png output/target/deps.dot > image.png
