[WebMacro-user] Expression Handling Again

[Dan M. <psi...@ya...>]

The usage of the StringMacro to use the #set directive
works great. I was wondering if there is anything
exposed to evaluate the expression without modifying
the context. 

This works great, but I would like to leave the
context as is, not adding new temp variables to the
context.

Context ctx = new Context();
ctx.put("val1", 1);
ctx.put("val2", 155);
Macro macro = null;
macro = new StringMacro("#set $val = $val1 + $val2");
macro.evaluate( ctx);
Integer val = (Integer)ctx.get("val");


I am looking forward to the 2.0 release.

[WebMacro-user] Release 2 Finalization

[Lane S. <la...@op...>]

Friends,

I will be working on WM during the next few days to finalize the 2.0 
release.

One thing that all of you could do is to comb thru the wiki pages and 
purge really old or obsolete pages. Update existing pages or create new 
ones which highlight uses or applications or examples.

There should be no new code committed to the head.

We should expect Release 2 to hit the street in the first week of October.

Thanks for your patience.

[Danni M. <psi...@ya...>]

Thanks that was exactly what I was looking for, I
didnt realize I could pass directives when
instantiating a StringMacro, and then retrieve the
value from the context. Thanks

Re: [WebMacro-user] Using WebMacro outside of a WebApplication

[Keats K. <ke...@xa...>]

I'm not clear on what your problem is.  It looks like you have the right 
idea.  You can evaluate a template to a stream or a String.  If you want 
to set other data types using WM, you can pull them out of the context 
after evaluating the template.

Something like:

            Context ctx = new Context();
            ctx.put("val1", 1);
            ctx.put("val2", 155);
            Macro macro = null;
            macro = new StringMacro("#set $val = $val1 + $val2");
            macro.evaluate( ctx);
            Integer val = (Integer)ctx.get("val");

Hope this helps.

[WebMacro-user] Using WebMacro outside of a WebApplication

[Danni M. <psi...@ya...>]

I would like to use the expression handling of
WebMacro outside of typical WebMacro. I have been able
to use a StringMacro which evalutates out properly,
but I would also like to evalute a full expression
such as $val + $val1 When I evaluate such an
expression I get String substitutions. Is there any
way to do this with WebMacro 2.0. I am not sure what I
should use to have this functionality, or if those
classes are public. I have a sample below of what I am
trying to accomplish. 

By the way I have to say I love the ideas and
implementation of WebMacro. Thanks

import org.webmacro.engine.StringMacro;
import org.webmacro.engine.MacroAdapter;
import org.webmacro.engine.StringMacroAdapter;
import org.webmacro.Context;
import org.webmacro.Macro;


public class Test {

    public static void main(String[] args) {
        try {



            Context ctx = new Context();
            ctx.put("name", "David");
            ctx.put("val1", 1);
            ctx.put("val2", 155);

            Macro macro = null;

            macro = new StringMacro("$name");
            System.out.println( macro.evaluate( ctx));

            macro = new
StringMacro("$name.substring(0,2).length()");
            System.out.println( macro.evaluate( ctx));

            macro = new
StringMacro("$name.substring(0,2).length()+5");
            System.out.println( macro.evaluate( ctx));

            macro = new StringMacro("$val1 + $val2");
            System.out.println( macro.evaluate( ctx));

            macro = new StringMacroAdapter("$val1 +
156");
            System.out.println( macro.evaluate( ctx));

            macro = MacroAdapter.createMacro("$val1 +
$val2");
            System.out.println( macro.evaluate( ctx));





        } catch(Throwable t){
            t.printStackTrace();
        }


    }
}

[WebMacro-user] Release 2 Update

[Lane S. <la...@op...>]

Friends:

I am completing a test suite against release 2 features. I am using
documented features from the web site. For example, I started with Keats
#bean directive and documentation example:

#bean $counts = "java.util.HashMap" scope=session onNew
  #set $counts.Hits = 0
#end
#set $counts.Hits = $counts.Hits + 1


This does not execute. Why? Because the WM evaluator does not cast the
expression

$counts.Hits + 1


into an Object (Integer). The expression

($counts.Hits + 1)


is cast.  So, my approach is three-fold:

1) publish issues as I discover them for discussion (as above)
2) get the documentation to line up with the reality of the version
3) provide a synthetic test with performance data for release 2 features.

I have digested Endre's diatribe on naming the release and i have
decided that he is right and it does need to be named WebMacro 2.0. So,
this will be the release ID.

Also, I think WebMacro could be one of the best foundations for an Ajax 
library. If there is anyone on this list who is doing work with Ajax, 
then let's get your work into a module or into the contrib section.

yours,

Lane,

Can you give more details on this?  I just cut and pasted from your 
message into a template and it worked fine for me.  What kind of error 
are you seeing?  What is your environment? 

Remember that the session scope will only work if you are using a 
WebContext (i.e., WM was instantiated with a Servlet argument).  If you 
are running in a non-Servlet environment, try changing the scope to 
application or global.

[WebMacro-user] Varargs...

[Nikhil G. D. <ng...@ce...>]

Webmacro doesn't recognize functions that take varargs as arguments. I 
think it must not be difficult to add this support considering the fact 
that it is treated like an array. However, I have no experience with 
this. Just the fact that it is becoming a problem because a lot of 
functions use varargs.

I find this -really- disturbing.

What are the stuff that have been "incrementally added" since the 2.0 
"rc1"??

There _has never been a 2.0 release_, and now the new release will be 
named 2.1??? This is really really silly - how will this be explained on a 
timeline and "history of WebMacro" pages, and what is the consistent 
explaination to the users?
  What-ever- the additions since the rc1, the new MAJOR versjon 2.0 should 
NOT be skipped. Going from one minor version, to a new minor version that 
have a higher -major- version is just NOT GOOD.

Can someone with their repos set up properly (I can't seem to update my 
anon copy anymore?!) do a diff between the rc1 and HEAD, please? Then 
we'll see whether this talk about "major changes" holds water.

Endre.

Re: [WebMacro-user] Possible eval/templet bug

[Keats K. <ke...@xa...>]

Marc,

I found that the new "string as templet" feature of #eval gives a nice 
workaround for this.

Try:

#setblock $render
Value is: \$value
#end

#templet $outerTemplet
   #set $value = "Hello!"
   #eval $renderString using {
      "value" : $value
   }
#end

#eval $outerTemplet using {
    "renderString" : $render
}

Re: [WebMacro-user] Possible eval/templet bug

[Lane S. <la...@op...>]

Keats,

What do you think of this? I looked at the logic and I think Marc is right.

I use #templet and #eval a lot and it seems that the contexts are not 
getting pushed correctly? Is there a bug in the stack?

Re: [WebMacro-user] WM down?

[Eric B. R. <eb...@tc...>]

Sorry guys.  Was on vacation last week.  Seems we've got a  
combination of a failing power supply and a battery backup that  
doesn't.  I'll try to get the situation resolved this weekend when I  
have some time.  However, she's back online now.

Paul, I appreciate the offer for a mirror, but I don't think it's  
necessary.  I just need to give the current box a little love and  
attention.

Re: [WebMacro-user] Release Work

[Lane S. <la...@op...>]

Hi Marc,

First, I like Spring for all of its architecture neutral advances. I am 
going to start using it regularly. I just do not like XML as a 
configuration language but since I use ant all the time, I can live with 
it. I know, for example, I could write a basic container using the #bean 
and #properties directives as IOC enablers in a few hours as a proof of 
concept.

I do not want WM to be Spring-dependent. So, let's be sure about that. 
Spring-friendly, absolultely. And, I will work with you on this.

I do not see the big character-flaw in the Broker or in the way WebMacro 
pulls its basic properties. Invoking an instance of WebMacro from a 
Spring Container should be very straight-forward as is and, if needs be, 
there could be Decorator to assist in the initialization of WebMacro. 
But, I will always keep an open mind.

Re: [WebMacro-user] Possible eval/templet bug

[Keats K. <ke...@xa...>]

Hey Marc.  I on vacation (with a very poor dial-up connection from the 
Delaware shore), but I did manage to look at this a bit. 

It's not actually a bug, although it certainly a head-scratcher.  The 
issue is that the arguments to #eval are evaluated before the macro 
(templet) whose context they are being added too.  Since your argument 
to $outerTemplet "renderTemplet" is a templet, and a templet is a Macro, 
WM attempts to evaluate it -- in the current context -- before passing 
it to the $outerTemplet.  Since there is no variable $value defined in 
the current context, you get an error.

The messed up error message is another issue.  It's a bit better if you 
use the CrankyEEH, but still a bit screwy.  I'll put this on my list to 
look at one of these days.

I'm not sure what the best solution is.  My first thought is to use 
#setblock to define your templet argument as a plain string, and then 
convert it to a templet within the outerTemplet or something.  I may 
play around with this and see if it works.

Good luck.

Why don't you put together a small doc work plan and we can get some of

Re: [WebMacro-user] Possible eval/templet bug

[Keats K. <ke...@xa...>]

[Resending ... didn't seem to go through yesterday.]

Hey Marc.  I'm on vacation (with a very poor dial-up connection from the
Delaware shore), but I did manage to look at this a bit.

It's not actually a bug, although it's certainly a head-scratcher.  The
issue is that the arguments to #eval are evaluated before the macro
(templet) whose context they are being added too.  Since your argument
to $outerTemplet "renderTemplet" is a templet, and a templet is a Macro,
WM attempts to evaluate it -- in the current context -- before passing
it to the $outerTemplet.  Since there is no variable $value defined in
the current context, you get an error.

The messed up error message is another issue.  It's a bit better if you
use the CrankyEEH, but still a bit screwy.  I'll put this on my list to
look at one of these days.

I'm not sure what the best solution is.  My first thought is to use
#setblock to define your templet argument as a plain string, and then
convert it to a templet within the outerTemplet or something.  I may
play around with this and see if it works.

Good luck.

a mirror?
