The #setprops directive would also be nice if the data is really coming
out of a property file; something like
#setprops as file "myprops.ini"
It would do the same as if the properties where typed in between your
accolades '{ .... }' and of course the content needs to get parsed, so
that the Type =3D $User.TYPE_STANDARD still works.
BTW the directive isn't mentioned in the directive page! (Hint)
I'm not that busy with Webmacro at this moment but want to thank you for
this enhancement. This keeps the project alive and kicking!
Keep up the good work everybody!

This is great news. I am planning on releasing WM as a buildable release that includes the body of the WebMacro tests. The release will be at once testable and useable out of the box. People like running the tests for a product to develop familiarity and confidence in the software.

I have (finally) committed the SetpropsDirective (fka PropertiesDirective). Documentation can be found at http://www.webmacro.org/SetpropsDirective. Unit tests can be found in org.webmacro.template.TestSetpropsDirective.java. As part of this effort, I also refactored the BeanDirective, allowing both classes to share a class loading mechanism that supports the AllowedPackages and ImpliedPackages configuration properties. (Other directive can also use this feature by invoking the org.webmacro.util.Instantiator class.) I have deprecated the BeanDirective prefix for these properties, so you should now just specify them like: AllowedPackages=java.util,org.webmacro.util ImpliedPackages=java.util,org.webmacro,org.webmacro.util Please try this out and give me feedback.

Thank you Keats and thank you Nick for your answers. I also thought about a kind of "Interceptor" for determining the template name before telling webmacro to fetch it. I just wanted to do this as transparent as possible for the user. So I probably have to use a custom include-directive. Thanks for your help! |

From: Nick S. <NSa...@ms...> - 2005-10-05 08:38:32

Hi
We do much the same thing but we use a simple interceptor context
tool.
We use an internationaliastion service to populate the context with a
language key
and then always use a call to the tool to find internationalised
templates.
eg
#include as template "$Paths.template("myResource.wmt",$DEFAULT_PATH))
where $DEFAULT_PATH is usuallly "en"
The tool caches the existing found paths for speed.
So if the site is in French you would get "fr/myResource.wmt" and so on
or if that didn't exist it would default to "en/myResource.wmt"
We use versions of the same tool for javascript,images,stylesheets
etc.
Regards
Nick

Sorry Sven. I'm afraid I don't quite understand what you are trying to
do and what isn't working. I'm pretty sure that the caching mechanism
is based on the template name, including the path, so you'll need to
determine the path before you attempt to retrieve the template.
If you give some more detail and maybe some code, we can try to be of
more help. It does sound like a very worthwhile project.

I'm curious about this benchmarking result. I can't figure out where
the savings would come from unless it is a trivial template. AFAICT the
only step that gets skipped is the the hash lookup which should be
fast. You still have to create the context, load the context, parse the
template, and expand the template. I suppose if the template is cached
and the context is reused as well and the template is simple, then it
would make sense.
There is probably some room for optimizing this even further ... a tool
to evaluate a WM expression without any output buffer (NullFastwriter?)
or even creating a variable. Hmmm ...

Hi,
I just finished my custom template loader for webmacro. Goal of it is
context-based template loading and internationalization . It takes a
template name ("index" for example), determines the directory where the
appropriate version resides and adds an internationalization suffix.
example:
Template "index" in the context of the site "testSite" for language "en"
results in "testSite/index_en.wm" to be loaded.
Works perfect. At least as long as I deactivate caching.
Cause unfortunately the CacheManager/Provider/whatever does not get
notice of that the template name changed. So it returns the en-version
when the de-version should be loaded and so on...
Is there a way to let the CacheManager/Provider/whatever know about the
changed template name?
I also tried to work around this and not determine the resulting name
_inside_ the loader but call the loader with the already computed name.
This works as intended but leaves include-directives untouched.
Thanks in advance for your help!
Sven

You should tie it into WMEval.java. Maybe like:
public Object evalExpr(Context ctx, String expression) throws
PropertyException;
I think it would be better to actually make the code available
somewhere rather than hide it away on Wiki. Also, there's a few
things that should be done to that little function. Namely, caching
of StringTemplates.

You don't. It's a TemplateVisitor, not a ContextVisitor.

It's also really fast. On the order of 20% faster than communicating
the value through the Context. Which is important if you're doing
this sort of thing over and over in web-requests.

Eric's method is nice. I do something similar (though less elegant) in
the PropertiesDirective. However for XML files there is a much simpler
method that I sometimes use: just parse the XML file as a template
before you parse the XML. Works great.
You can use doubles in WMScript, but not natively with the built-in
operators. You can use the $Math tool and the casting functions, like
$toDouble.

That method works great to get the result. One last
thing, how come webmacro expressions do not return
double. Is that historical? Now that we use a grammar
and parser for WM can is it possible to expand
expressions?

Rather than creating a StringMacro, create a StringTemplate, with a
mini-template of:
#set $foo = $x + 1
Then use a custom TemplateVisitor to pull out the "SetValue" argument
of the #set directive:
static class MyTemplateVisitor extends TemplateVisitor {
Object value;
public Object getValue() {
return value;
}
public void visitDirectiveArg(String string, Object object) {
// the #set directive has 2 arguments: "SetTarget" (LHS)
// and "SetValue" (RHS). We're only interested in
"SetValue"
if (string.equals("SetValue")) {
value = object;
}
}
}
So, you're code will be something like:
public Object evalExpression (Context context, String expression) {
StringTemplate tmpl = new StringTemplate (context.getBroker(),
"#set $foo = " + expression);
MyTemplateVisitor visitor = new MyTemplateVisitor();
template.parse();
template.accept(visitor);
Object value = visitor.getValue();
if (value instanceof Maco) {
return ((Macro) value).evaluate(_context);
} else {
return value;
}
}
Hope this helps.

I guess what I was wondering about was using the api
directly stepping in before the #set places the result
into the context. I was looking into the src for
PropertyMethod and trying to figure out how to get the
result.
I am using webmacro throughout a webproject, and would
like to use similiar webmacro expression in xml files
which are read and processed. Thanks

AFAIK there are only two ways to get something out of a WM template
expansion -- capture the result of the expansion, or pull something from
the context. Actually I suppose you could use the #bean directive to
create a "global" variable and then get it from the Broker.
Maybe if you can explain your requirements we could think of a way of
doing what you want.
