Since C2 is an evolution of C, this page is here to summarize the changes made and the design philosophy behind it.

Language changes

• no Header files

  consequence: import statement and modules

• no forward declarations

  philosophy: types the same thing twice, reduces development speed

  consequence: requires a multi-pass compiler

• member access always through dot-operator ' . ' , not sometimes ' -> '

  philosophy: remove clutter/reduce change effort

• Unified type definitions

• All global variables are initialized by default

• Standardized attribute syntax

• better external library control

• Improved operator precedence

• No auto-fallthrough in switch cases

• no arrays as function arguments

• removed do .. while, since it's not needed without macros and error prone

New Features

While C2 introduces some NEW features, these dont break the C philosophy and are mainly Syntax cleanup, syntactic-sugar or remove a C anti-pattern:

• BitOffsets

• Type-functions

• Modules

• Internal build-system

• Incremental arrays

• Switch statement on strings

• Auto-arguments

• Multi-condition case statements

• Sane printf format specifiers

• Compiler Plugins

• Raw strings

• init calls

• init list assignment

• More tooling integration like dependency and refs file generation
