Example 1 with ConditionalOpNode

use of com.google.template.soy.exprtree.OperatorNodes.ConditionalOpNode in project closure-templates by google.

the class MsgIdFunctionPass method handleMsgIdCall.

/**
 * Rewrites calls to msgId($msgVar) to either a static constant message id or a conditional if
 * there is a fallback.
 */
private void handleMsgIdCall(FunctionNode fn, MsgFallbackGroupNode msgNode) {
    ExprNode replacement;
    long primaryMsgId = MsgUtils.computeMsgIdForDualFormat(msgNode.getChild(0));
    if (msgNode.numChildren() == 1) {
        // easy peasy
        replacement = createMsgIdNode(primaryMsgId, fn.getSourceLocation());
    } else {
        long fallbackMsgId = MsgUtils.computeMsgIdForDualFormat(msgNode.getChild(1));
        ConditionalOpNode condOpNode = new ConditionalOpNode(fn.getSourceLocation());
        FunctionNode isPrimaryMsgInUse = new FunctionNode(BuiltinFunction.IS_PRIMARY_MSG_IN_USE, fn.getSourceLocation());
        // We add the varRef, and the 2 message ids to the funcitonnode as arguments so they are
        // trivial to access in the backends.  This is a little hacky however since we never generate
        // code for these things.
        // We could formalize the hack by providing a way to stash arbitrary data in the FunctionNode
        // and then just pack this up in a non-AST datastructure.
        isPrimaryMsgInUse.addChild(fn.getChild(0));
        isPrimaryMsgInUse.addChild(new IntegerNode(primaryMsgId, fn.getSourceLocation()));
