Conventions

In this book, you will find a number of styles of text 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, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Suppose we have a set of variables, where $PORTAL_VERSION represents the current portal version and $LIFERAY_PORTAL represents the working folder containing the portal that we are planning to install."

A block of code is set as follows:

terms.of.use.journal.article.group.id=$ARTICLE_GROUP_ID
terms.of.use.journal.article.id=$ARTICLE_ID

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

permissions.checker=com.liferay.portal.security.permission.AdvancedPermissionChecker

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

$LIFERAY_HOME=$LIFERAY_PORTAL/liferay-portal-$PORTAL_VERSION

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "In the Liferay 6.2 control panel, under the Apps | Store link section, you will see apps that are stored in the Marketplace portlet."
