# valac-0.34(1)

compiler that translates Vala source code into C source and header files

## 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.
