Example 3 with PrintDirectiveNode

use of com.google.template.soy.soytree.PrintDirectiveNode in project closure-templates by google.

the class GenPyExprsVisitor method visitPrintNode.

/**
 * Visiting a print node accomplishes 3 basic tasks. It loads data, it performs any operations
 * needed, and it executes the appropriate print directives.
 *
 * <p>TODO(dcphillips): Add support for local variables once LetNode are supported.
 *
 * <p>Example:
 *
 * <pre>
 *   {$boo |changeNewlineToBr}
 *   {$goo + 5}
 * </pre>
 *
 * might generate
 *
 * <pre>
 *   sanitize.change_newline_to_br(data.get('boo'))
 *   data.get('goo') + 5
 * </pre>
