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

- --color=,WHEN/
-
Enable color output, options are 'always', 'never', or 'auto'
-
When no value is given always is implied. When neither --color
or --no-color are declared then --color=auto is used where
output is colored when stderr is a terminal.

- --enable-version-header
-
Write vala build version in generated files
- --disable-version-header
-
Do not write vala build version in generated files
- --run-args
-
Arguments passed to directly compiled executable
- --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.
