Most common docblock for Delphi and/or FreePascal code

Question

I'm quite familiar with PHP dockblocks since it's been my job for the last 15+ years.

/**
  * Description
  *
  * @tag bla bla
  * @tag more bla bla
  */

What I'm trying to understand is if there is a standard like that for Delphi and/or FreePascal.

From my analysis on an awful lot of code I never seen any, but I could be dead wrong.

Answer 1

It looks like doxygen has a tool which can be used in conjunction to document Pascal and Delphi code. Maybe that will help you.

Answer 2

Latest Delphis support parsing of XML documentation. They also use this information in hints (for example if you move the mouse cursor over a method name).

I'm using this template for method documentation:

///<summary></summary>
///<param name=''></param>
///<returns></returns>
///<exception cref=""></exception>
///<since>2009-04-15</since>

Answer 3

On a project I'm currently working on, we're using DelphiCodeToDoc, which works reasonably well. Its syntax looks like this:

type
  {* This is an example class }
  TMyClass = class
  private
  protected
  public
    {* Does some twiddling with AParam, and returns the result as String
       @param AParam Input value
       @return AParam incremented by 2, as String
       @throws Exception 'Boo' if it's full moon }
    function MyFunction(AParam: Integer): String;
  end;

Answer 5

There are several standards, usually depending on the documentation tool being used. We use PasDoc, so we adhere mostly to its format http://pasdoc.sipsolutions.net/ which is based on JavaDoc.

Alternatively, there is XMLDoc as gabr pointed out and there are quite a few other tools, most having similar syntax with subtle differences.

Answer 6

I prefer docs outside of the source (it always gets messy), and use the excellent fpdoc that comes with FPC. (FPC's own docs are written in it).
