Hi,
I've hit upon what I believe is an obscure bug in #eval/#templet in 2.0 RC1.
I'm finding it with my JSP taglib but I don't believe it is specific to
the taglib, it smells more like a problem with #templet/eval. Of course a
unit test will prove this so that will naturally be my next course of
action. However I can't commit to WM from my workplace.
...evaluating this template:
<html>
<body>
#templet $render
Value is: $value
#end
#templet $outerTemplet
#set $value = "Hello!"
#eval $rendertemplet using {
"value" : $value
}
#end
#eval $outerTemplet using {
"rendertemplet" : $render
}
</body>
</html>
...the intention/expectation is that this will simply output:
<html>
<body>
Value is: Hello!
</body>
</html>
...but, rather weirdly, you get this:
<html>
<body>
Value is: <!-- Attempted to write an undefined variable: Hello! at
render:4.11 -->
</body>
</html>
Notice that it says undefined variable "Hello!" - but that is the value of
the variable! It's like it's trying to recursively evaluate it.
Keats - any thoughts?
I will try to dig into the source and write a unit test for this, but I
wanted to flag it in case I'm being stupid.
Also, there seems to be an error handling bug. If your innermost templet
references a non-existent variable, you get something like:
Value is: <!-- Attempted to write an undefined variable: <!-- Attempted to
write an undefined variable: $iknowthisdoesntexistvalue at unknown:2.58
--> at render:4.11 -->
...notice that this has two error messages and unbalanced "-->" so you get
some nasty output in the page and interestingly two sources - unknown and
render. Also note that it gets the error variable name right in this case,
but in the first problem I talked about it uses the -value- of the
variable as the "unknown" variable name.
Very confusing!
Cheers

YES PLEASE! IntelliJ IDEA rocks (we should be applying for the free open source licenses for the core WM developers..... <g>). I have in the past setup basic syntax highlighting which is better than nothing, but we should do as much as possible to make WM easier to use. We need to seriously consider how to present "WebMacro Extras" to the world - i.e. not core download components but a clear, well-maintained list of extra tools... just like those Velocity people ;-( |

Hi We have a simple plugin that we use with webmacro and intellij 4. It highlights text and gives a macros panel that you can use to jump to macro definitions.

Let me qualify this a bit more - in my "dream" of WM 3 we'd have POJOs
that let us configure a WebMacro instance - both initially at startup
using somethign like Spring, but also at runtime for non-persistent
changes to the config such as temporarily adding a new directive. A Spring
bean config XML might look like this:
<beans>
<bean id="myBusinessLogic" class="com.somecorp.LogicClass">
<property name="datastore" ref="myJDBCstorage"/>
</bean>
<bean id="myJDBCstorage" class="com.somecorp.JDBCStorageClass">
<property name="datasource" value="java:comp/env/jdbc/TestDB"/>
</bean>
<bean id="someDirective" class="com.somecorp.SomeDirectiveClass">
<property name="datastore" ref="myJDBCstorage"/>
</bean>
<bean id="webmacro1" class="org.webmacro.WebMacroConfiguration">
<property name="baseConfiguration" value="file:wm.properties"/>
<property name="contextTools">
<map>
<entry key="logic" value-ref="myBusinessLogic">
</map>
</property>
<property name="directives">
<map>
<entry key="specialdirective" value-ref="someDirective">
</map>
</property>
</bean>
<bean id="webmacro2" class="org.webmacro.WebMacroConfiguration">
<property name="baseConfiguration" value="file:wm2.properties"/>
<property name="contextTools">
<map>
<entry key="logic" value-ref="myBusinessLogic">
</map>
</property>
</bean>
<bean id="uiController1" class="com.somecorp.MyUIController">
<property name="webmacro" ref="webmacro1"/>
</bean>
<bean id="uiController2" class="com.somecorp.MyOtherUIController">
<property name="webmacro" ref="webmacro2"/>
</bean>
</beans>
Now for anyone not familiar with Spring, the above will create a bunch of
Java objects (using the "class=" attribute value) calling their default
constructors and then will automatically set the properties on those
objects including resolving references to other beans within the context,
independent of order in the XML file.
Anyway, the above shows how simple it would then be to configure WebMacro
for a single application that has:
* Multiple WM instances, initialized from different config
* WM instances initialized with context tools that are configured with
references to other configuration-domain objects -without- the use of ugly
singletons in your application, or arguably worse JNDI (yes I used a JNDI
datasource just to save space...). Remember, those beans referenced by the
WM config could be anything, and exist anywhere. Your WM setup /
application no longer needs to know.
* Wiring of WM instances to other components such as your controllers/actions.
This is -great-!
It would also be possible to allow configuration of Context "templates" so
that whenever WM needs a new context it takes it from a bean factory
configured in the Spring XML - thus externalizing this config from WM and
most importantly integrating it with Spring applications.
Like the XML or not Lane, -lots- of people out there are using Spring and
havnig WM non-configurable from it is very ugly indeed, forcing you or
end-users to understand and use multiple configuration schemes/tools.
It makes WM much less attractive. I haven't checked but I'm pretty sure
that Velocity config is Spring friendly.
$0.02 :)

Guys, I just looked at the "tutorial" that comes with the WM distros. I've never noticed this before - and it's quite nice. However: 1. it is woefully out of date, especially in terms of the available directives, map syntax etc 2. in my opinion in starts off too far from WM script - start with "Hello world" and then tell them why :) 3. It has no styling 4. It has no TOC. I don't have time now, but for when I do - does anybody have any reason why I shouldn't do some work on those docs to improve them? Ditto the Wiki - it's in a bit of a mess and using WM as an "end user" on site I am noticing lots of holes in the docs / structure of them. Cheers |

I think you've got the wrong end of the stick here. The Spring bean config stuff is geared at application component initialization (i.e. business logic objects, EJBs - yuck!, etc) Its XML grammar is trivial, and you are not restricted to their XML - you can write any bean factory implementation that uses any file format you like. i.e. you could write a WebMacroBeanFactory for spring that parses WM templates to initialize the bean context. However Spring's XML config is very good because it can be validated using any standard XML validation tool (and as part of the build process) and 99% of the world knows a lot more about XML than WebMacro. Whatever, WebMacro configuration needs to be "bean scriptable". I am not suggesting any replacement of the existing properties config scheme for WM - but it -must- be possible for users to configurable WebMacro at runtime, and from any POJO configuration tool such as Spring, Pico etc. Right now the WM config/context system is not really "POJO".

Hi Keats,
If you will put a wiki page on this, I think it will be very nice
convenience.
If it is good to go and well tested, let's include it in the release, too!

I've found it annoying when I have to set more than a couple of
properties. Also it's cool to be able to initialize an object's state
from a properties file.

I don't think the documentation is a big issue. I'll put up a Wiki
page. And it's not like WM requires much support these days. I'm not
wedded to this, it's just something that comes in handy for me and
someone else wanted it as well, so I put it out there.
Thanks for carrying the ball.

Be sure to add some unit tests. btw: have you ever thought of just doing a WM Container? In fact, this might be a really nice subproject because it would show how to run WM in both standalone and in Web-mode. Also, I see a limitation with XML property specification ala Spring. First, I do not like XML as a bean property spec. I would much rather use #bean to instantiate and set props . Second, it does not allow for the beans properties to persist in state and then evolve. Fine for the default settings of a bean. I have done a lot of work over the years with property modeling and it drives me crazy to see static XML machinery for initializing beans. A WM init script using #bean would and is such a cleaner way: #if ($Store.AppParams == null) { $AppParams = #defaultParameters("AppParams") } #else { $AppParams = $Store.AppParams } is so much more readable then a bunch of angle bracket statements and proprietary type definitions. I am so tired of learning yet another XML type schema. Don't get me wrong though.

Hi Keats,
Do you really want to include this in the pending 2.1 release?
Have you considered that you now have to document 2 ways to set a
property, #properties and #set? Will this confuse a new person to
WebMacro? Is your #property ... a big advantage over #set
$Object.Property = "foo"
It is certainly a nice convenience. Just not sure that its inclusion
will improve more than its support and documentation demands will warrant.

I created a new directive called Properties directive. This can be
handy if you want to set a bunch of properties on an object within a
template; essentially providing a abbreviated, readable syntax. You can
also combine it with the #include directive for processing a properties
file. (Just be careful of comments: use "##" or "# " to keep them from
confusing the parser.)
I'm attaching the source and I will commit it to the core if folks agree
it is worthy.
Here's some test WMScript that illustrates the usage:
## Test using default object: java.util.Properties
#set $Name="Keats Kirsch"
#set $Age=45
<h3>\#properties test</h3>
#properties $p {
Name: $Name
Age = $Age
}
My age is $p.Age<br>
My name is $p.Name<br>
## Test using a pre-existing POJO (non-map)
<h3>More \#properties</h3>
#bean $Cal="java.util.Calendar" scope=static
#set $GCal=$Cal.Instance
Today: $GCal.Time, FirstDayOfWeek: $GCal.FirstDayOfWeek, Lenient:
$GCal.Lenient
<br>
#properties $GCal {
FirstDayOfWeek=0
Lenient=false
}
Today: $GCal.Time, FirstDayOfWeek: $GCal.FirstDayOfWeek, Lenient:
$GCal.Lenient
<br>

Actually it is possible to modify the configuration dynamically. I
haven't tried this but the following should work:
Properties props = new Properties();
props.setProperty("someProperty", "someValue");
broker.getSettings().load(props);

If we are going to skip 2.0 and go straight for 2.1 with "early access" Spring and JSP I will commit this stuff tomorrow. The WM Spring code I have is simply a conversion of the Velocity Spring view for WM. There is an outstanding issue in that Velocity supports a "spring.vm" macro that is on the classpath in spring.jar and you can pull it in from any template as just "spring.vm" I believe. We can't do this easily as far as I can see, as we need to modify the WM config from within the Spring view code, which means overriding any webmacro.properties etc. ...which is why for WM 2.5 or 3 I am committed to overhauling the core configuration, Broker and resource handling stuff so that it is bean-like, not singletons, and therefore IoC/DI friendly. Keats and I haven't merged our ideas on the JSP taglib yet. I will get to this this week. Cheers -- Marc Palmer Managing Director, AnyWare Ltd. |

Hi Nikhil, # # FastWriter Configuration # # Misconfiguration of these settings can cause severe performance # and resource penalties This is an exagerrattion and I have changed it. The refresh rate is in milliseconds. When a file changes on disk, there is not an event so it has to be polled. This is what has to occur. Every 1000 millis, check for changed templates and return the next generation of a cache. Lane Nikhil G. Daddikar wrote: > Thank you for your answer.

Thank you for your answer. I have two questions: 1) what are those FastWriter settings in WM.properties, there is a note there that it will "significantly" affect performance but it doesn't tell me how. 2) Is the refresh rate specified in seconds? Also, I don't understand it's purpose. Why would I want it to reload after some specific time? I would only want it to load after it changes. Right? Thanks again.

WM Faithful, I am undertaking Release 2 work. I would like the release to be 2.1. Also, eric, please get the webmacro.org site back up and announce this to the group. As soon as this is done, I would like respective authors of their pages to go in and refresh those pages. Also, I would strongly urge that a bridge between WM and Spring be completed. This is really important because Spring is a useful container for application execution and it supports different add-on tools. The people who have expressed interest here should do the logical thing: get an IM session running, describe the work, and, just do it. An Eclipse plug-in is a must. Someone, (hint, hint) needs to do this and submit it to me for inclusion in the release. I would like to write an article for Java World on WebMacro. Any others who want to help out are more then welcome. regards, -- Lane Sharman Providing Private and SPAM-Free Email http://www.opendoors.com 858-755-2868 |

Hello Nikhil, About 2 years ago, we had a very intense development/dialog/experimentation with caching. All of this resulted in a pluggable architecture. Brian Goetz provided this architecture on the whole. I wrote a caching system, which is best called a "generational system". I use it in all of my wm apps. #entry in webmacro.properties: CachingProvider.template.CacheManager: org.webmacro.resource.GenerationalCacheManager CachingProvider.url.CacheManager: org.webmacro.resource.GenerationalCacheManager # Set reloading to true since we are in development mode by default. GenerationalCacheManager.*.ReloadOnChange: true # The refresh rate for incorporating changes to the mutable image GenerationalCacheManager.*.RefreshRate: 1000 The RefreshRate is the most important for performance purposes. It means: "if the cache has not been updated for this amt of time, and there are stale changes, and there is an idle interval, then replace the current generation with a newer generation.". Since updates occur only to the prospective cache, the current cache is read-only and therefore not subject to syncrhonization. Give it a try! Lane Nikhil G.

Yes the #eval/#templet mechanism is the way to go. You get a new context for each iteration with a reference to the original context. There's an example in the unit tests you can look at.
