Next lets us have a look at how to properly document functions and their arguments. You can also add some description about the file to be shown in the Documentation as shown in the screenshot below.Īs you can see, the file name and description are placed on the documentation page generated for this example file main.c Just use the Doxygen “structural command” followed by the file’s name, to tell Doxygen that you want this file to be included in the documentation generation process. If there is no file header then Doxygen will not produce documentation for that file. This must be present at the top of every file which needs documentation. Step 2.1: File headersįile headers contain detailed description about a given file. Let us see how you can use Doxygen entities to document your source code at various levels. file name must be present in the file header for inclusion into the documentation generation documentation for page markdown page for the “table of contents” for the markdown page Here another special Doxygen syntax is used which is the syntax.ĭoxygen calls these structural commands.There are several of them and the most useful ones are the following. Next, let’s look at the documentation of parameters. The Doxygen generated documentation from the code above will look like this The entities and tags are implemented in code as shown in the screenshot above. What is an entity in Doxygen? An entity can be a global variable, a structure declaration, enum declaration, or a function. The above 2 syntaxes must be placed just above an entity so that the Doxygen parser can associate the comments to that particular entity. in C we just need 2 slashes for a comment line) These syntaxes are used to tell the Doxygen parser that it is documentation and it needs to be extracted. Note the extra asterisk (*) in line 1 of the first option and extra slash symbol(/), (i.e. The 2 simplest methods to include in C source code are Let us see some of those before we actually get into using them! Doxygen tags and symbols to use in your commentsĭoxygen supports several methods for incorporating documentation inside the comments. If you got till here, congratulations, you have finished the first step of installing Doxygen software on your PC! Step 2: Learn How to Document the code using Doxygenĭoxygen works by taking the comments which are specifically formatted according to Doxygen’s pre-agreed syntax.ĭoxygen calls these special syntaxes as “Tags”. Once you open that app, you must see something like shown in the screenshot below. The software should be under the name “Doxywizard” as shown in the screenshot below. Once that is done you should be able to launch the Doxygen software from the windows start menu. I recommend keeping the default settings while doing so. Then go through the usual installation steps to finish installing Doxygen on your Windows PC. Click on the “down arrow icon” then click “Keep” and Doxygen should start downloading. On Google’s Chrome Browser you will see something like this on the bottom right corner. Your browser might now ask you for confirmation whether you wish to download an executable, say yes as shown in the screenshot below and you should be good to go! But don’t worry, just right-click the link and click on “ save link as” to get the software as shown in the screenshot below. If nothing happens after you click, then probably your browser is preventing you from downloading the executable. If you scroll a bit down, till you see something like this.Ĭlick on the link highlighted in the red box above to get the software. You can opt in for notifications regarding updates using the form shown in the screenshot below link So head over to the Doxygen official website given in the link below and download the latest release of Doxygen. In this article, our focus will be on how to get started to actually start using Doxygen. If yes, then how to get started using Doxygen?.If no, then what are the alternatives available?.That is just the short version of the answer, read my other article for a longer and more informative answer where I try to answer the following questions In other words, Doxygen is a software specifically made to fulfill the need for producing and maintaining documentation with as little effort as possible. and delivers in various formats like HTML, PDF, etc. What is Doxygen? Doxygen is a software used to produce documentation of source code written in C, C++, Python, Java, etc. Let us start by looking at what Doxygen is. In this tutorial, let us learn about the Documentation software Doxygen and see how to make use of it to make the job of producing documentation more automated and stress-free!
