If it should be as simple as possible, we should use something like this:

<sourcesyntaxhighlight lang="csharp">

using GLib;

Line 20 ⟶ 18:

print ("Hello World\n");

}

</syntaxhighlight>

</source>

However, it would be useful to have a second example, then, that shows a bit more of the syntax.

::If it were to be as simple as possible you could drop the glib import and just have the one-liner:

<blockquote><blockquote><sourcesyntaxhighlight lang="csharp">

void main() { print("Hello World\n"); }

</sourcesyntaxhighlight></blockquote></blockquote>

:Ps. As an example of how easy it is to wrap C libraries, one can copy the default glib-2.0.vapi somewhere and edit it to wrap g_chdir by putting the following code under the DirUtils namespace, then compiling with the switch --vapidir=/path/to/modified/vapi:

<blockquote><sourcesyntaxhighlight lang="csharp">

[CCode (cname = "g_chdir")]

public static int chdir (string pathname);

</sourcesyntaxhighlight></blockquote>

:Which then be used from Vala code:

<blockquote><sourcesyntaxhighlight lang="csharp">

DirUtils.chdir( "/foo/bar" );

</sourcesyntaxhighlight></blockquote>

Line 147 ⟶ 145:

the line:

<syntaxhighlight lang="text">

<code>

stdout.printf("hello world!\n");

</codesyntaxhighlight>

means that <code>stdout</code>, which is an instance of the streams class, which is capable to process the <code>printf("hello world!\n")</code> message.
