We should also ask ourselves if we even need a DSL when trying to solve our problems, because sometimes they add more layers of complexity than the original problem. In the next chapter, you'll learn about editing Clojure programs with the Emacs and Leiningen applications. For additional information and documentation, please refer to the chapter information sources in the next section. [ 31 ] Design Concepts with Clojure This chapter will go over some basic concepts that apply to software development in any programming language.
If the example function does anything else other than parse lines of XML input, it is probably badly designed and will cause confusion when trying to debug errors in our programs. This practice will help us keep our functions to a more reasonable size and can also help simplify the debugging process. Patterns for success If you're reading this book, you're probably already familiar with some of the programming principles that'll be covered in this chapter. Don't feel discouraged if you don't and please review these principles if you do.
We can also use (pattern) and (chord) to modify how the note sequences are played. If we wish to play each note at the same speed, we will simply use the (p) function and a sequence of musical note symbols. If we want the speed of the playback to progress for each musical note, we will wrap the sequence of notes in the (pattern) function. The (pattern) function not only accepts a sequence of musical notes, but also accepts a duration integer, which will play each note for the stated duration. The following are two examples of playing the musical pattern of the notes A4 and B4.
