[htmltmpl] Feature Idea [TMPL_VIRTUAL]

[Jason P. <ja...@jo...>]

How about a new tag, either as part of the standard distribution or a 
plugin:

TMPL_VIRTUAL

The one thing that I like when I'm doing PHP pages is that I can build 
singular dynamic components and simply include them from the parent 
template.

i.e.

# FILE: index.php
<? virtual( 'helloworld.php' ); ?>


# FILE: helloworld.php
<? print "Hello World!"; ?>

Yes, I know about Philipp's Widgets articles[1] on perl.com, but you 
still need to put the encapsulation logic in your code, which seems 
redundant.

How about if the HTML_VIRTUAL called LWP to request the URL and replace 
the tag w/ the response's content?

# FILE: index.TMPL
<!-- TMPL_VIRTUAL URL="helloworld.php" -->

# FILE: helloworld.php
<? print "Hello World!"; ?>

Re: [htmltmpl] escape html whitespace

[Matt T. <mt...@as...>]

Thanks for the quick reply.  This question may be beyond the scope of
this mailing list, but...

I am pulling data from a database view that adds spaces to create
alignment.  For example:

* AZ300~30ST Full-Width Std Thic
  AZ300~18ST Full-Width Std Thic
* AZ360HD~36HD 20in Tandem St
  AZ360HD~20HD 20in Tandem St
  AZ360HD~24Z 20in Tandem St

I am replacing the leading spaces before writing the data to a select
box's option tag.

I tried adding style="white-space: pre;" to the option tag, but that
made all the new line characters show up.

I tried putting a div tag, with style="white-space: pre;" around the
contents of the option tag.  That didn't have any effect.

<select name="partid">
	<option  value="AZ300R2F3S2">
		<div style="white-space: pre;">* AZ300~30ST Full-Width Std Thic	(AZ300R2F3S2)</div>
	</option>
	<option  value="X000564">
		<div style="white-space: pre;">  AZ300~18ST Full-Width Std Thic	(X000564)</div>
	</option>
</select>							

I am sure there are other solutions, but &nbsp; is the first thing that
came to mind.

Matt

Hi Sam,

One of the mods that I made to my local copy of H::T was to allow the
ESCAPE modules to be dynamically loadable so that users could implement
escaping according to whatever rules they had.

Would you be interested in a patch to allow this feature?

Don't do that?    really shouldn't be needed in modern HTML

ahh - my bad - I should have been *much* more clear about what I was 
talking about.

Often the requirement for needing UTF8 is to be able to translate a 
website into multiple languages, while using the existing templates.

One problem with this is that the static text within the template is 
that it wont be translated into the target language.  One solution is 
simply to get the template translated - however this means that each 
time the sites' layout changes, the new templates need to be translated 
again.  An alternate solution is to store the static text within the 
application, then use TMPL_VAR's to output the text - thus allowing 
lookup of the static, into the target language.

Why would you need a hack to get UTF8 strings into the templates?  Is
there a bug I should be fixing here?

-sam

Re: [htmltmpl] How to handle UTF-8?

[Mathew R. <mat...@ne...>]

I worked on a product which was translated into 6 languages; we supplied 
templates in ASCII and used TMPL_VAR's to output the appropriate 
UTF8-encoded string.

ie: there are no real problems if your templates are just layouts and 
the content is provided by TMPL_VAR's.

As an aside, there are a number of different techniques used to get the 
UTF8 strings into the templates, eg: TMPL_VAR's, hacks to H::T, using 
H::T::E with a callback.

the reformist "templates in UTF-8 (and generic support for PerlIO layers)":

I am curious to learn what is the current best practice for those of us

I don't think the DEFAULT= parameter to TMPL_VAR was available when I
wrote ::Set. In any case, to set a variable and not output it
immediately, one would have to wrap the statement:

<TMPL_IF NAME=never><TMPL_VAR NAME=title DEFAULT=Page Title></TMPL_IF>

which seems a lot more trouble than

<TMPL_SET NAME=title VALUE=Page title>

Also, if you set a value with DEFAULT=, you can't query it
programmatically via $template->param().

Good day!

We serve lots of WAP pages with HTML::Template. So this is my old WML

What I did for bailii.org (and various other sites based on that code)
is a very simple approach: every page does a <tmpl_include> of the "top"
and "bottom" templates, which wrap the page-specific content. Using my
HTML::Template::Set module extension, the page template can then pass
variables to the included templates (such as the page's title).

[htmltmpl] Base templates and sub templates

[Rudolph F. <rud...@gm...>]

Hi,

I'm new on this list. I've a question on using HTML::Template for a
larger project:
- I will use a base template which defines the basic structure of the site.
- Different parts of the template will have dynamic content (generated
by the scripts).
What 'd like to do is create the base template and then create
seperate subtemplates (one per page). Every sub template only defines
the dynamic parts of the page. This sub template should then inherit
the base template to fill these parts.

What is the recommended approuch and/or best practice for such a setup?

Rudolph

There is a performance hit, but only at template-parse time.  ie: if you 
use caching there is no performance hit.

Ah, I'm getting all misty-eyed thinking about my youth. Long live the
TRS-80!

As an aside, H::T filters have other great uses. For instance I use [% and
%] instead of < and >  (e.g. [%rem%] and [%/rem%], and use [%=myvar%], [%IF
mycondvar%], [%LOOP myloopvar%] instead of <tmpl_var name="myvar">, <tmpl_if
mycondvar>, <tmpl_loop myloopvar>). This means that the editors that our
designers prefer don't barf or complain about syntax errors when using
HTML-like tag delimiters, and it also means that I don't lose my H::T code
in all the HTML tags

One way is to use H::T filters. You could have something like <rem> and
