| - | ====== Introduction ====== | + | ====== Overview ====== |
| The purpose of this guide is to give you, our intrepid contributor, an overview of the Mixxx codebase. Mixxx is a big project with millions of lines of code so it can be daunting at first. If you know how to get around then it really isn't that big and scary. | The purpose of this guide is to give you, our intrepid contributor, an overview of the Mixxx codebase.

| ====== Prerequisites ====== | ====== Prerequisites ====== | ||
| + | First, you will need to download the code of Mixxx [[using Git]]. | ||
| + | |||
| + | To understand this guide, you should have a working experience with a systems language like C, C++, or Java. You should be able to get by with trial and error even if you don't know these. It will help significantly if you have some experience with the [[http://doc.qt.io/|Qt Framework]] which Mixxx uses extensively. | ||
| + | |||
| + | We recommend you review these sections of the Qt documentation to get familiar with aspects of Qt that we use heavily: | ||
| + | * [[http://qt-project.org/doc/latest/signalsandslots.html|Signals & Slots]] | ||
| + | |||
| + | If you're not familiar with C++, [[https://www.youtube.com/watch?v=18c3MTX0PK0&list=PLlrATfBNZ98dudnM48yfGUldqGD0S4FFb|The Cherno Project]] on YouTube has a good series dedicated to the core concepts. | ||
| - | To understand this guide, you should have a working experience with a systems language like C, C++, or Java. You should be able to get by with trial and error even if you don't know these. It will help significantly if you have some experience with the [[http://qt.nokia.com/products/|Qt Framework]] which Mixxx uses extensively. | + | We also highly recommend that you use a C++ IDE rather than a text editor. Mixxx is a huge project spread across hundreds of source code files. IDEs index the entire code tree and allow you to jump from where a function is used to its definition, even if that is in another file (which it often is). Without this powerful tool, you will spend a lot of time simply finding the code you're looking for instead of understanding what it is doing. We have [[developer tools#using IDEs|guides]] for setting up several IDEs to work on Mixxx, but feel free to use whatever IDE you prefer. |
| + | We highly recommend these resources from the Xiph.org Foundation for background information on digital and analog signal processing: | ||
