Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The ~ symbol is a shortcut for the user's home directory, such as /home/daniel."

A block of code is set as follows:

<search>
 <filter name="item_not_done" 
 string="Not Done" 
 domain="[('x_is_done', '=', False)]" />
</search>

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

<search>
 <filter name="item_not_done" 
 string="Not Done" 
 domain="[('x_is_done', '=', False)]" />
</search>

Any command-line input or output is written as follows:

$ createdb MyDB
$ createdb --template=MyDB MyDB2

Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Click on the debug icon and select the Edit Action option. This will open the Window Actions used to open the current Views."

Warnings or important notes appear like this.

Tips and tricks appear like this.
