valac - compiler that translates Vala source code into C source
and header files
valac [OPTION]... [FILE]...
Vala is a programming language that aims to bring modern
programming language features to GNOME developers without imposing any
additional runtime requirements and without using a different ABI compared
to applications and libraries written in C.
- valac, the Vala compiler,
is a self-hosting compiler that translates
- Vala source code into C source and header files. It uses the GObject type
system to create classes and interfaces declared in the Vala source
code.

- --disable-version-header
- Do not write vala build version in generated files
- --run-args
- Arguments passed to directly compiled executeable
- --abi-stability
- Enable support for ABI stability
This changes the current behaviour to output public
members of classes and interfaces the same order as they appear in Vala
source. For libraries is recommended to use --abi-stability to ensure
the maintainability of the resulting Application Binary Interface (ABI). This
option is disabled by default for backward compatibility because it can break
ABI of existing projects.
