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.

Usage:

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

-D, --define=SYMBOL...

Define SYMBOL

--main=SYMBOL...

Use SYMBOL as entry point

--nostdpkg

Do not include standard packages

--disable-assert

Disable assertions

--enable-checking

--disable-since-check

Do not check whether used symbols exist in local packages

-k, --keep-going

Keep temporary files

--profile=PROFILE

Use the given profile instead of the default, options are 'gobject' or 'posix'

-q, --quiet

Do not print messages to the console

-v, --verbose

--no-color

Disable colored output, alias for --color=never

--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.
