An Introduction To Programming With Processing Source Code Editor A source code editor is a textual editor within an IDE. The Source Code editor in an IDE is designed specifically for programming purposes and not for wordprocessing, so generally text formatting capabilities such as bold, italicising characters or directly editing characters colors is not permitted within source code editors. The source code editor within the PDE allows you to type code, and access Processing's API. Modern day source code editors use color codes to distinguish different types of data, this is referred to as syntax highlighting and it helps to make code more human-readable. Build Automation Tools Programming can involve many repetitive tasks, build automation tools help programmers perform these repetitive tasks by use of tools built into the IDE. They might include the IDE's ability to convert source code to machine readable code with the click of a single button (the button being the build automation tool) or the ability to export your source code to multiple platforms with a menu Why Learn Programming using Processing? 40
An Introduction To Programming With Processing selection. In the PDE several build automation tools for creating Processing applications can be found under the Tools and Sketch menus more generic build automation tools can also be found in the other menu's in the PDE. Some of Processing's build automation tools. Processing's build automation toolset can also be extended by downloading tools from processing.org/reference/tools/ Compiler and /or Interpreter Most modern day IDE's have a compiler and/or interpreter, as this is the feature within IDE's that enable the conversion of source code to machine readable code. It is in this feature that our code is given a “meaning” for a computer to implement and for us to observe, interact with and experience in what ever it's intended form of implementation. You might be wondering at this point what exactly is the difference between a compiler and an interpreter? The truth is that there is actually not much of a difference between what a compiler does and what an interpreter does. The terms stem from a “Compiled Language” and an “Interpreted Language”. As mentioned before in order for a computer to make any sense of our code it needs to convert this code into a machine readable format, this process of conversion is referred to as compiling. The process is specific because the code must be fed into a compiler in a specific language and then be compiled into another “language” which is no longer human-readable but machine readable and specific to a particular platform. A compiler is said to perform this task on the entirety of the source code once so that when the program is compiled there is no more conversion or compilation that needs to be performed there after. An interpreter differs in the sense that the source code is not compiled into a specific machine readable format. So how does the code run on a machine? The code is passed to an interpreter (which is another software application) that runs the code. The interpreter then determines how the code should be run continuously translating the code from a higher level to a machine readable level Why Learn Programming using Processing? 41
