VALAC(1)

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

  Help Options:

-?, --help
    Show help options

  Application Options:

--vapidir=DIRECTORY...

    Include binding for PACKAGE

--vapi=FILE
    Output VAPI file name

--library=NAME
    Library name

--shared-library=NAME
    Shared library name used in generated gir

--gir=NAME-VERSION.gir
    GObject-Introspection repository file name

-b, --basedir=DIRECTORY
    Base source directory

-d, --directory=DIRECTORY
    Change output directory from current working directory

--version
    Display version number

--api-version
    Display API version number

-C, --ccode

-c, --compile
    Compile but do not link

-o, --output=FILE
    Place output in file FILE

-g, --debug
    Produce debug information

--thread
    Enable multithreading support (DEPRECATED AND IGNORED)

--enable-mem-profiler
    Enable GLib memory profiler

-D, --define=SYMBOL...
    Define SYMBOL

--main=SYMBOL...
    Use SYMBOL as entry point

--nostdpkg
    Do not include standard packages

--disable-assert
    Disable assertions

--enable-checking
    Enable additional run-time checks

--enable-deprecated
    Enable deprecated features

--hide-internal
    Hide symbols marked as internal

--enable-experimental
    Enable experimental features

--disable-warnings
    Disable warnings

--fatal-warnings
    Treat warnings as fatal

--disable-since-check
    Do not check whether used symbols exist in local packages

-k, --keep-going
    Continue as much as possible after an error

--enable-experimental-non-null
    Enable experimental enhancements for non-null types

--enable-gobject-tracing
    Enable GObject creation tracing

--cc=COMMAND
    Use COMMAND as C compiler command

-X, --Xcc=OPTION...
    Pass OPTION to the C compiler

--pkg-config=COMMAND
    Use COMMAND as pkg-config command

--dump-tree=FILE
    Write code tree to FILE

--save-temps
    Keep temporary files

--profile=PROFILE
    Use the given profile instead of the default

-q, --quiet
    Do not print messages to the console

-v, --verbose
    Print additional messages to the console

--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.

--target-glib='MAJOR.MINOR', or 'auto'
    Target version of glib for code generation

--gresources=FILE...
    XML of gresources

--gresourcesdir=DIRECTORY...
    Look for resources in DIRECTORY

--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 executeable

--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.
