// Compile command (requires gtk4 package to be installed):
// valac --pkg gtk4 ExampleApp.valaWhy Vala?
- Clear and familiar syntax - Based on C, C# and Java
- Object-oriented when you need it - Built-in support for classes, interfaces, inheritance and more, but you can also just use procedural programming features instead.
- Automatic memory management without overhead - Vala uses ref counting by default, so you won't have to worry about managing memory in most programs
- C interoperability - Use GObject-based C Libraries via binding files or call C functions directly from Vala
- Compiles to native binaries - Extremely fast program execution times and no virtual machine or runtime environment is required to be installed for execution
- Modern language features - Type inference, null safety, generics, lambdas, async/await
- First-class GObject and GTK support - Optional, but unmatched when you need it
What can you build?
- GUI Applications
- Perfect integration of GTK, Libadwaita and Granite makes development super simple. Easily publish your apps on Flathub without bloated packages.
- Command Line Programs
- Use a large standard library and many third-party libraries available for use in Vala.
- Libraries
- Provide bindings for many other languages and API documentation without manual work. Also, dynamic and static linking are both supported.
