C3 Language

C3 is a C-like language trying to be "an incremental improvement over C" rather than a whole new language. C3 is based on the ideas of the C2 language: to iterate on top of C without trying to be a whole new language.

C3 tries to be an alternative in the the C/C++ niche: fast and close to the metal.

Design Principles

Procedural "get things done"-type of language.
Try to stay close to C - only change where truly needed.
Flawless C integration.
Learning C3 should be easy for a C programmer.
Dare violating the "close to metal" principle if the value is great.
Not an object oriented language.
Avoid "big ideas".
Avoid the kitchen sink language trap.

Current status

Most work is still being done in the design draft here: https://c3lang.github.io/c3docs/. If you have suggestions, send a mail to christoffer@aegik.com, file an issue or discuss C3 on the r/ProgrammingLanguages Discord server: https://discord.gg/cfu4wdk

There are some small work being done on the parser here, but most of the structure is still missing:

What's missing in the parser

asm sections.
Macro parameter lists to imports.
auxiliary data for enums.

What's missing in the semantic analyser

No handling imports.
Function signatures incomplete.
Function typedef not done.
asm not done.
catch, throws and try statements.
generic not analysed.
attribute not analysed.
$switch and $for not handled.
Enums not correctly handled.
Errors not correctly handles.
Type resolution not complete for all types.
type not handled.
?: not handled.
Identifier analysis incomplete.
Macro call not handled completely.
Function calls not handled completely.
Struct initializers not complete.
No analysis of [] nor .someMember.
Missing analysis of assign expressions.
Not all casts implemented.
Varargs.

What's missing overall

Exactly how the module system should work together with the import is still under discussion.
Exactly how the library imports should work is not 100% decided.
The compiler currently only works in single file mode.
Integration with C.

What's working?

The compiler can compile simple programs, but integration with C is mostly missing, which means that little can be displayed outwards.
Lexing and parsing works (except for the exceptions noted above).

If you wish to contribute with ideas, please file issues on the c3docs: https://github.com/c3lang/c3docs instead of the compiler.
