valac

Compile a vala file, with gtk+

$ valac [path/to/file.vala] --pkg [gtk+-3.0]

$ valac --version

$ valac --help

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

Treat warnings as fatal

--disable-since-check

Do not check whether used symbols exist in local packages

-k, --keep-going

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

Minimum runtime dependency: 'gobject' (default) or 'posix' (minimal libc)

gobject enables GLib's GType runtime type system. The runtime environment will usually require libgobject and its small number of dependencies. posix removes the dependency on GLib and disables the runtime type system. The profile either generates alternative code or errors at compile time if a Vala language feature is used that requires the runtime type system. This is useful for writing code, for example, that targets microcontrollers or for extremely small system utilities or container images. The runtime environment will usually require a small subset of the ISO C standard library.

-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 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.
