[htmltmpl-java] Hello?

[<co...@qu...>]

Hi,

is this project still being maintained?
I've started using it for a small project of mine,
and I see some potential for improvements on your
template engine.

Bye,

You can just tell HTML.Template where to look for templates by passing 
the "path" key to your Template constructor:

 	String [] template_init = {
 		"filename",  "my_template.tmpl",
 		"path", "webapps/todo",
 		"search_path_on_include",   "true"
 	};

 	Template t = new Template(template_init);

Hope this helps.

[htmltmpl-java] Exception: No such file or directory

[<je...@ne...>]

Hi again :-)

I am almost there! ... I just have one thing I need to figure out. My
application is in:

/usr/share/tomcat5/webapps/todo

And my templates is in the same directory. For example, I have a template
named projects.tmpl. But my application can't find the template, so I
printed out the current directory:

out.print(System.getenv("PWD"));

The above command returns: /usr/share/tomcat5

So I need to add "webapps/todo" in front of every template filename... of
cause I don't want to do that. Instead I would like to make the
application believe that it's root directory is
/usr/share/tomcat5/webapps/todo.

Can you tell me how to do that?

Thanks :-)

It's okay... I have managed to build a *.jar by adding the java files to =
a
new project in eclipse, and then use the export function.

I can't wait to use it! :-)

There isn't one, and I can't build java classes on my current box (can't

Myabe you need to add the current directory to your classpath.

I haven't seen this happen in the past, and I don't have access to a 
java box right now, so can't say for sure.

[htmltmpl-java] Problems with WebSphere & Parser class

[Raul L. <rl...@ab...>]

Hello.

I=B4m a developer=B4s Java.=20
I found a problem with WebSphere application server.
The WebSphere Studio Application Developer is 5.0.
I use JSDK 1.4.2, Oracle 8.
In Parser class, line 124:
stringbuffer.append(stringbuffer1);

The error line of Server console is the next:
'[19/04/04 9:21:51:812 CEST] 6b0be68d WebGroup=20
E SRVE0026E: [Error de servlet]-[java.lang.StringBuffer:=20
method=20
append(Ljava/lang/StringBuffer&#59;)Ljava/lan
g/StringBuffer&#59; not found]:=20
java.lang.NoSuchMethodError: java.lang.StringBuffer:=20
method append(Ljava/lang/StringBuffer;)
Ljava/lang/StringBuffer; not found'



Solution is the next:

Original code Parser.java :

if(s1.indexOf("tmpl_") < 0)
{
     stringbuffer.append(stringbuffer1);
continue;
    }


New code Parser.java :

if(s1.indexOf("tmpl_") < 0)
{
     String aux=3D stringbuffer1.toString();
String aux2=3D stringbuffer.toString();
aux2+=3Daux;
     stringbuffer=3Dnew StringBuffer(aux2);
     continue;
    }



Please, somebody can upload this correction in the next=20
release?

Sorry for my English :(

well, it can't be implemented because tmpl_include is processed much 
before the variables are handled.  basically, when the template is being 
read, all tmpl_includes are read in and inserted at the relevant 
positions.  It's only after all this has happened that tmpl_vars are 
processed.

furthermore, adding this feature will break compatibility with the 
HTML::Template perl module.

It can be done with a Filter, when that's done.  I'm still working on 
it.

you can do this with the path and search_path_on_include parameters to 
the constructor.  Since this is done programmatically, you can have the 
path read from a configuration file.  This is the way I do it.

All include templates will be in a static location.  Just include that 
path in the path variable, and specify only the template filename in the 
tmpl_include, and not the full path.

eg:

global_templates/
   include_1.tmpl
   include_2.tmpl

local_files/
   main1.tmpl
   main2.tmpl


main1.tmpl:

<tmpl_include file="include_1.tmpl">


main1.java:
	set path to /path/to/local_files, /path/to/global_templates
	set search_path_on_include to true
	initialise template

[htmltmpl-java] tmpl_include

[Thomas W. <tw...@im...>]

Hi,

thanks for your help with the new constructor ... works fine!


Another question:

I will use the <tmpl_include> tag to include many html fragments in my
whole html-site. The feature request is the following:

i will try this code in html:

<tmpl_include <tmpl_var body1> >

but this does not work at the moment (i know why, it is not yet
implemented ;-).

so can you expand the html-java-tmpl library to make this work? I will
shortly explain you, why i need this:

I use html-java-templates in a servlet environment. So to install the
servlet on many plattform i have a config file for the servlet
environment. In this config file i will tell the servlet global include
html-templates (these templates will also have tmpl_vars). So when i
move the servlet i must never update all my global templates to change
the path to these html-templates. I must only change the config and the
rest goes dynamicly.

What you think about?

Thanks and Regards

Waffel

you should use either the Hashtable style constructor or the Array style 
constructor.  Both are documented in the HTML.Template API docs.

[htmltmpl-java] deprached constructor

[Thomas W. <tw...@im...>]

Hi,

i have downloaded the html-tmpl-java sources 0.1.2 from sourceforge,
compiled the code with jdk1.4 an tried it.

When i use following code (on the html-tmpl-java homepage the example
does the same):

Template templ =3D new Template("myTemplate.html");

the the java compiler says to me:

"the constructor Template(String) is deprached"

what kind of constructor should i now use, to create a new
template-class from a given template file?

Thanks a lot

doable, but will take a bit of time as I'm tied up with work.  If you 
think you could hack it in and send me a patch, that would be cool.

That's a good question ... I suppose I'm looking for the same functionality
as the perl HTML::Template params() method.  That returns all the top level
tmpl_if, tmpl_include, tmpl_loop, tmpl_unless, and tmpl_var parameters.
I've never tested for a parameter inside a loop, just the loop itself.

RE: [htmltmpl-java] testing for parameter existence

[Costantino, D. <Dan...@gs...>]

Philip,

I downloaded and tested the new Template.java and tested the containsKey()
method.  Unfortunately, this method only works after a call to setParam().
For example, suppose I have the following in my template file:

<tmpl_var name = foo>

if (t.containsKey("foo")) {
	// succeed
}
else {
	// fail
}

that will always fail unless I do the following:

t.setParam ("foo", "bar");
if (t.containsKey("foo")) {
	// succeed
}
else {
	// fail
}

Then it will succeed.

For my purposes, I need to know if a parameter exists before I set its
value.  Is this a piece of functionality which could be added?

Please let me know.

Thanks
-Dan

Currently this seems to be the only way, but I think it is reasonable 
enough to add another method that will do what you want.  Expect it in 
the next version, or get CVS in a few hours.

Philip,

Thanks for getting back to me.  I did a little more testing and realized my
try {} .. catch {} wrapper really doesn't solve the problem.  It turns out
that getParam() will throw a NoSuchElementException exception on a valid
parameter if the parameter's value has not yet been set.  I'll stop short of
calling that a bug, but I think it's a serious problem.  Is that the
intended behaviour?

[htmltmpl-java] testing for parameter existence

[Costantino, D. <Dan...@gs...>]

Hi,

I want to test for the existence of a parameter in a template.  How can I do
this without generating a java.util.NoSuchElementException?

At present, I simply wrap each getParam(<test_name>) call around a try ...
catch block.  This seems inefficient.  Is this the only way to do it?  I
only trying to determine if the template variable exists in the specific
html template I'm presently reading.  I don't actually need its value.

Thanks

[htmltmpl-java] [Announce] HTML.Template.java v 0.1.2

[Philip S T. <phi...@gm...>]

Version 0.1.2 is out.  Minor bugfix.  TMPL_VARs inside TMPL_LOOPs were
case sensitive always.  This has been fixed.

[htmltmpl-java] [Announce] HTML.Template.java version 0.1.1 has been released

[Philip S T. <phi...@gm...>]

For those who don't know, HTML.Template.java is a java implementation of
HTML::Template.  It is almost completely compatible with
HTML::Template.pm

The only thing not supported are the caching directives and filters 
(which are on the way).

By popular demand, this release has the global_vars option.  
die_on_bad_params has also been included.  

The tutorial on the website has also been updated to reflect some of the 
newer constructs.

Homepage: http://html-tmpl-java.sourceforge.net/

Changes in current release:

ver 0.1.1

- Fixed bug in tmpl_var which failed if parameter was not a String
- TMPL_VAR and TMPL_LOOP now give a reasonable error message if parameter is 
of the wrong type
- Var.typeOfElement now actually returns the type and not the name
- support for die_on_bad_params
- support for global_vars
- New __COUNTER__ TMPL_LOOP context variable
- Can now set default values for TMPL_VARs through the template:
<TMPL_VAR name="myvar" default="default_value">
