5. Tutorials

This section provides hands-on tutorials organized into four groups:

Language Tutorials — learn daslang syntax and standard library features
C Integration Tutorials — embed daslang in a C host using the daScriptC.h API
C++ Integration Tutorials — embed daslang in a C++ host using the native daScript.h API
Macro Tutorials — write compile-time code transformations using the daslang macro system

5.1. Language Tutorials

These tutorials introduce daslang’s core features step by step. Each comes with a companion .das file in tutorials/language/ that you can run directly:

daslang.exe tutorials/language/01_hello_world.das

The tutorials are designed to be followed in order. Each one builds on concepts introduced in earlier tutorials.

5.2. C Integration Tutorials

These tutorials show how to embed daslang in a C application using the daScriptC.h API. Each tutorial comes with a .c source file and a companion .das script in tutorials/integration/c/.

5.3. C++ Integration Tutorials

These tutorials show how to embed daslang in a C++ application using the native daScript.h API. Each tutorial comes with a .cpp source file and a companion .das script in tutorials/integration/cpp/.

5.4. Macro Tutorials

These tutorials teach daslang’s compile-time macro system: call macros, reader macros, function macros, and AST manipulation. Each tutorial has two source files — a module (.das) that defines the macros and a usage file that exercises them — because macros cannot be used in the same module that defines them.

Run any tutorial from the project root:

daslang.exe tutorials/macros/01_call_macro.das
