People should be allowed to use what ever tool they want to read the documentation. Out of source documentation forces users that are interested in the documentation to open some external tool for reading the documentation, like a browser of pdf reader.Ī lot of people do not like to leave their IDE or editor if itâs not required. If done so developers do not need to leave their editor/IDEs to look up the documentation for a class or method.Ä®verything is available at fingertip, very convenient. blank line, then Doxygen file documentation block, blank line and after that the contents of the. It requires that documentation is written in a form which closely. File and directory naming File structure Code format. In the case where there is already a file with this name, doxygen renames the same to .bak prior to the creation of the configuration template. In order to extract documentation from the header files of the project, we use doxygen.Suppose you are not using the name of the file in that case, a file will be created with the name as Doxyfile. If you omit the file name, a file named Doxyfile will be created. To do this call doxygen from the command line with the -g option: doxygen -g where is the name of the configuration file. Modern IDEs have the possibility to show documentation found to a method on mouse over of a method call.įor this to work it basically means that the documentation for public functions need to be written into the header files. Here, the is the configuration fileâs name. To simplify the creation of a configuration file, doxygen can create a template configuration file for you.not just the one where the documentation comment is), according to the docs, doing just file will document the current file. This of course requires your IDE or editor to support jumping to a definition.Ä®very IDE or editor thatâs worth to use supports this functionality. While using file myfile.ext works in any file (ie. It is nice that, when writing a function call in C or C++, to jump to the definition of a function and find the corespondent documentation there. Writing documentation should not make anything harder, it should make things simpler. This is redundant information and together with the extra work it makes refactoring much harder. These extra tags need to stay in sync with the code, what is extra work. This means the usage of extra tags for the element you document. Writing documentation not beside the documented elements means that you need to specify what to document over and over again. To me, keeping the code clean from documentation sounds already wrong. The only pro argument I heard so far for out-of-source documentation is to keep the code clean.
