NAME

SYNOPSIS

10       valac [OPTION]... [FILE]...
11

DESCRIPTION

13       Vala  is  a  programming  language  that  aims  to  bring  modern  pro‐
14       gramming  language  features  to  GNOME developers without imposing any
15       additional  runtime requirements  and  without using  a different   ABI
16       compared to applications and libraries written in C.
17
18       valac, the Vala compiler, is a self-hosting compiler that translates
19              Vala  source  code  into  C source and header files. It uses the
20              GObject type system to create classes and interfaces declared in
21              the Vala source code.
22

214       --abi-stability
215              Enable support for ABI stability
216              This changes the current behaviour to output public  members  of
217              classes  and  interfaces  the  same order as they appear in Vala
218              source.  For libraries is recommended to use --abi-stability  to
219              ensure  the  maintainability of the resulting Application Binary
220              Interface (ABI).  This option is disabled by default  for  back‐
221              ward   compatibility  because  it  can  break  ABI  of  existing
222              projects.
