PasDoc ยป IncludeCodeTag

The tag @includeCode includes an external file inside the documentation, treating it as Pascal source code. The included code will be nicely displayed (with colors, bold keywords and so on). This is useful to show longer example programs in the documentation. The fact that you keep the example code in a separate file allows you to check the correctness of your example code by compiling it.

For example, consider you want to document a function LoadImage in your unit. You can write:

{ Loads the image from file, creating new TImage instance.
  Remember to free it later. Example usage:
  @includeCode(load_image_example.pas) }
function LoadImage: TImage;

The load_image_example.pas is a normal Pascal program showing the usage of the LoadImage function.

The filename (load_image_example.pas in the example above) is relative to the Pascal source file defining this identifier (LoadImage in the example above). You can use something like @includeCode(../docs/load_image_example.pas) to refer to a different directory.

You can include multiple source code files (place each filename on a separate line), they will simply be glued together. Like this:

@includeCode( demo1.dpr demo2.dpr )

  • If you want to include an external file that is not a Pascal code (but may contain description using more PasDoc @tags) then use @include tag instead.

  • If you want to show a multi-line Pascal code inside the documentation, but don’t want to place it a separate file, then use @longCode tag instead.
