Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, path names, dummy URLs, user input, and Twitter handles are shown as follows: "Just assign the names of the layers you want to activate to the admin/reports/dblog environment variable."

A block of code is set as follows:

hello_world.logger.channel.hello_world:
    parent: logger.channel_base
    arguments: ['hello_world']

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Users can now reach this page from the module administration page by clicking on the Help link for each individual module that has this hook implemented."
