instantiated for all relevant sets of template arguments, or that is a private implementation detail of a class, is allowed to be defined in the one and only .cc file that instantiates the template. There are where possible. Just #include the headers you need. A “forward declaration” is a declaration of a class, function, or template without an associated definition. • Forward declarations can save compile project. • When using a function declared in a header file, always #include that header. • When using a class template, prefer to #include its header file. Please see Names and Order of Includes for rules about

format into a KiCad PCB. At the moment only the 3D Plugin Class has been developed and it will be the focus of this document. Implementing a Plugin Class requires creating code within the KiCad source tree Within the KiCad source tree, the file plugins/ldr/pluginldr.h declares the base class for all plugin loaders. This class declares the most basic functions which we would expect to find in any KiCad plugin the available plugins. The header plugins/ldr/3d/pluginldr3D.h declares a loader for the 3D Plugin Class. The loader is responsible for loading a given plugin and making its functions available to KiCad

Terminology notes In this document, unless otherwise clarified: 1. The term class is used inclusively to mean an “ordinary” class, enum class, interface or annotation type (@interface). 2. The term comment always basics 2.1 File name The source file name consists of the case-sensitive name of the top-level class it contains (of which there is exactly one), plus the .java extension. 2.2 File encoding: UTF-8 copyright information, if present 2. Package statement 3. Import statements 4. Exactly one top-level class Exactly one blank line separates each section that is present. 3.1 License or copyright information

The base exception for a module should be called Error. class Error(Exception): pass • Never use catch-all module-level variables are done when the module is imported. Decision: Avoid global variables in favor of class variables. Some exceptions are: • Default options for scripts. 5 • Module-level constants. For link￿ Nested/local/inner classes and functions are fine. Definition: A class can be defined inside of a method, function, or class. A function can be defined inside a method or function.

Sections with class unnumbered will never be numbered, even if --number-sections is specified. 18 Options affecting render TeX math as far as possible using Unicode characters. Formulas are put inside a span with class="math", so that they may be styled differently from the surrounding text if needed. However, this
