Extending opC++ With Custom Dialects

Dialects in opC++ allow you to specify language extensions and how their syntax is generated into code.

Dialects are written in a simple C-style language - simply called the opC++ Dialect language.

opC++ uses dialects to allow you to easily create and share your own language extensions. By using opC++ Dialects, you can add language extensions, share them, and swap out extensions - all without libraries or complicated integration.

Add dialects to add features, it's that simple.

Extended C++ Syntax

opC++ always enables extended C++ syntax:

• public, private, protected modifiers
• uninline modifier - specify to output functions to generated source code.

Dialects in opC++ make it possible to extend the C++ language in many ways:

• category : class, struct, category
• modifier : const, volatile, modifier
• valued modifier : modifier(value)
• enumerations : enum, enumeration
• initialization : type x = ...;

In fact, Standard opC++ (Serialization, Reflection) is entirely written as an opC++ Dialect. The compiler first reads your dialects so that it knows how to parse your extended code. It then parses your opC++ code files and generates standard C++ code based on the code generation rules in your dialect files.

Simple Dialect File

Here we declare a new category called uclass, and generate a 'Super' typedef if a uclass declaration has single inheritance.

We generate the typedef in the class body via a note.

We can also pass many types of arguments from the category to the note.

Visual Studio Addin

opC++ comes with an addin to improve coding in Visual Studio.

Some of its features include:

• Easy access to compiler options.
• Automatically integrates compiling for opC++ code.
• Navigation between generated, dialect, and original code.
• Visualization of code and dialect output.
• Context menus for aiding dialect development.

opC++ Toolbar

Easily clean and compile opC++ code and access project settings.

Navigate between generated code, code and dialect files, and visualize your code all from the opC++ toolbar.
