Class ExtractMsgVariablesVisitor

java.lang.Object

com.google.template.soy.basetree.AbstractNodeVisitor<SoyNode,R>

com.google.template.soy.soytree.AbstractSoyNodeVisitor<Void>

com.google.template.soy.jssrc.internal.ExtractMsgVariablesVisitor

All Implemented Interfaces:

NodeVisitor<SoyNode,Void>

public class ExtractMsgVariablesVisitor
extends AbstractSoyNodeVisitor<Void>

Moves MsgFallbackGroupNodes to separate {let} and print nodes. We then move the let node to the nearest block ancestor, so that the print node can be emitted as an expression instead of a statement. After this pass, all MsgFallbackGroupNodes will only appear inside LetContentNodes.

TODO(lukes,slaks): Rewrite any code relying on this pass to instead take advantage of the code chunk api.

exec(com.google.template.soy.soytree.SoyNode) must be called on a full parse tree.
