NAME

       valac  -  compiler  that  translates Vala source code into C source and
       header files


SYNOPSIS

       valac [OPTION]... [FILE]...


DESCRIPTION

       Vala  is  a  programming  language  that  aims  to  bring  modern  pro-
       gramming  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.

   Usage:
              valac [OPTION?] FILE... - Vala Compiler

       --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 back-
              ward  compatibility  because  it  can  break  ABI  of   existing
              projects.
