Go provides excellent support for both basic and complex I/O. The recipes in this chapter will explore common Go interfaces that are used to deal with I/O and show you how to make use of them. The Go standard library frequently uses these interfaces, and they will be used by recipes throughout the book.
You'll learn how to work with data in memory and in the form of streams. You'll see examples of working with files, directories, and the CSV format. The temporary files recipe looks at a mechanism to work with files without the overhead of dealing with name collision and more. Lastly, we'll explore Go standard templates for both plain text and HTML.
These recipes should lay the foundation for the use of interfaces to represent and modify data, and should help you think about data in an abstract and flexible way.
In this chapter, the following recipes will be covered:
- Using the common I/O interfaces
- Using the bytes and strings packages
- Working with directories and files
- Working with the CSV format
- Working with temporary files
- Working with text/template and html/template
