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 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.

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

              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.
