Title: Vala Plugin Example
Slug: vala
## Vala Plugins
> You **MUST** have the Vala bindings installed on your system for this to
> work. They are built by the default GPlugin build.
### Example Vala Plugin
Due to the way `GPlugin.PluginInfo` info works, you must subclass it and set
your values in the new constructor. It is recommended that you define this
class in a namespace to avoid collisions with other plugins.
Like all plugins in GPlugin, Vala plugins must also implement the
`gplugin_query`, `gplugin_load`, and `gplugin_unload` functions. These
functions must be in the global namespace.
The following is a basic Vala plugin.
```vala
using GPlugin;
namespace BasicPlugin {
public class Info : GPlugin.PluginInfo {
public Info() {
string[] authors = {"author1"};
Object(
id: "gplugin/vala-basic-plugin",
abi_version: 0x01020304,
name: "basic plugin",
authors: authors,
category: "test",
version: "version",
license_id: "license",
summary: "summary",
website: "website",
description: "description"
);
}
}
}
public GPlugin.PluginInfo gplugin_query(out Error error) {
error = null;
return new BasicPlugin.Info();
}
public bool gplugin_load(GPlugin.Plugin plugin, out Error error) {
error = null;
return true;
}
public bool gplugin_unload(GPlugin.Plugin plugin, out Error error) {
error = null;
return true;
}
```
