Hello,
I have the following problem : I would like to call a macro but the macro
name must be a variable.
Ex: instead of #renderLabel($component) to have #call("renderLabel"
$component) - of course "renderLabel" can be any (existing) macro name.
I started to create a directive #call, but of course the render method fails
because the nodeTree is not initialized. nodeTree is initialized during
parsing like this
public class ASTDirective extends SimpleNode {
...
directive = rsvc.getVelocimacro( directiveName,
context.getCurrentTemplateName());
try
{
directive.init( rsvc, context, this );
}
..
{
Any thoughts? I think such a directive is very useful, I don't know why is
not part of the library.
Thanks.
CallDirective source code :
public class CallDirective extends Directive {
public String getName() {
return "call";
}
public int getType() {
return LINE;
}
public boolean render(InternalContextAdapter context, Writer writer,
Node node) throws IOException, ResourceNotFoundException,
ParseErrorException, MethodInvocationException {
if (node.jjtGetNumChildren() < 1) {
rsvc.error("#" + getName() + " : invalid number of parameters,
must be at least the macro name and 0..N parameters");
return false;
}
String macroName = (String) node.jjtGetChild(0).value(context);
VelocimacroProxy velocimacro = (VelocimacroProxy)
rsvc.getVelocimacro(macroName, context.getCurrentTemplateName());
if (velocimacro == null) {
rsvc.error("A macro with name '" + macroName + " in context '" +
context.getCurrentTemplateName() + "' doesn't exists");
return false;
}
return velocimacro.render(context, writer, node);
}
}
