Most Java coders will be familiar with the auto-generated documentation that can be created with JavaDocs. The idea is to add comments into the code in a semi-structured way that can then be extracted into an easy to navigate help file.

The C++ world also has a number of documentation auto-generators, with Microsoft’s SandCastle and Doxygen being two leaders. I decided to see how well Doxygen could document MQL5, which is in essence a customised subset of C++. To me this is an important step in the maturity of MQL5, because the complexity of the language is easily capable of fostering some quite large class libraries.

The experiment worked very well and I believe the help documentation that Doxygen produces from MQL5 code will add a great deal of value.
