![]() This is purely aesthetic, and is not required.Īll three syntaxes will produce the same result, if done in Xcode. Note: In options two and three, there is an additional asterisk on each line in-between the required opening and closing lines. Note that these are similar to “normal” comments, except that there’s an extra / in option 1, and an extra character in the first line of options 2 and 3 ( * and !, respectively). * Your documentation comment will go here / Your documentation comment will go here There are three styles of comments that HeaderDoc scans for: Basically it scans your files for comments made in a particular style. HeaderDoc is a tool that you can either run from the command-line, or is automatically run by Xcode. Let’s see how you can use HeaderDoc to make creating documentation for these classes super easy. Right now, these files are barely documented. MathAPI: Contains a helper method to add two numbers.Car: Contains a few properties, and a method to “drive” a car and run a block upon completion.This is a simple little test project that includes two main helper classes: Learn about a third-party tool to make documentation even easier ( VVDocumenter-Xcode)ĭownload the starter project for this tutorial, and build and run.Generate HTML documentation from your comments.In this HeaderDoc tutorial, you will learn how to: In addition, Xcode parses HeaderDoc-style comments behind the scenes to automatically present your documentation in quick look panels. HeaderDoc is a command line tool that you can use to automatically generate nice HTML documentation for your code – as long as you structure your comments in a particular way. * \return The error return code of the function.When Xcode 5 and iOS 7 were announced, a small addition was mentioned that most people might have missed: HeaderDoc. * \param c Description of the parameter c. * \param b Description of the parameter b. * so you do not really need to read this section. There is nothing which really needs your notice, * \note This text shall only show you, how such a \"note\" section * because this text is basically saying nothing. * is totally senseless and you really do not need to read this, * \details This function does something which is doing nothing. Details followĪnd finally here an example for a full documentation of a function with doxygen: /** / Brief description which ends at this dot. If JAVADOC_AUTOBRIEF is set to YES in the configuration file, then using JavaDoc style comment blocks will automatically start a brief description which ends at the first dot followed by a space or new line. This command ends at the end of a paragraph, so the detailed description follows after an empty line. One could use the \brief command with one of the above comment blocks. * A brief description in one short sentence.įor the brief description there are also several possibilities: ![]() ![]() * \brief A brief description in one short sentence. All commands in the documentation start with a backslash () or an at-sign example /** To structure and fomat the generated documentation, Doxygen provides a large number (> 170) of special commands. Note the 2 slashes to end the normal comment block and start a special comment block. Some people like to make their comment blocks more visible in the documentation. The next alternative is to use the Qt style and add an exclamation mark (!) after the opening sequence of a C-style comment block: /*!Ī third alternative is to use a block of at least two C++ comment lines, where each line starts with an additional slash or an exclamation mark: /// The first and most common one are C style comments with an extra asterisk in the comment start sequence, e.g.: /** There are several ways to mark a comment block as a detailed description, so that this comment block is parsed by Doxygen and added as a description of the following code item to the documentation. ![]()
