I'm not a template novice and I still complain about the extra line
breaks. I think it's debatable whether "they are right there in the
template."  If the lines the <tmpl_*> tags are on are not actually
(template) content, I don't see why the line ends of those lines
should be considered emitable (template) content. The fact that so
many novices find this unintuitive would indicate it's not the correct
behavior.

But, if it would burden H:T with cumbersome logic, I've always been in
favor of leaving it alone for the sake of simplicity (which I like
about H:T).

RedHat/Apache .... it's "our" server (we're
the only ones with access to the machine), with root
access limited to myself and one other programmer
more savvy then me, and neither of us have
accessed the machine. We also have a
SSH and FTP script that sends us logon events
and there was no host access in the time frame of
the change. We also specifically requested *not* to
have any "auto-updates" of the OS and related items.

It's really weird, and I know at some point, we'll
find the cause ... and wouldn't be surprised if it
turns out to be a "duh" event. I'll certainly post
to the list when we do pin it down.

Appreciate the input, and if you have any other
random thoughts, don't hesitate to pass them along

Must have not been good for you anyway.

And you didn't open and save the files with a mac?

I put your template section in one of my templates.
Here is the result:

##########################################
=> this represents line 1
=> this represents line 2
=> this represents line 3
=> this represents line 4
=> this represents line 5
##########################################


I haven't updated my Template modules for at least 
a year, maybe two. so it could be something 
in the Template system that has changed
or something weird in your machine.
I remember I was using a perl categorizer and 
there was an auto update and it wrecked my 
whole categorization system, so I stopped updates.

What kind of server is it on?

Re: [htmltmpl] Addendum/Correction to: Template output for email scripts adding extra line breaks

[C H. <hag...@ep...>]

Thanks for the response .... you mention:

--------------------------
The above doesn't look like a template file, so I'm
not sure I'm actually answering your question, but I tried a couple of things.

1.  I put the above <template></template> lines in a file named qt.tmpl,
and ran the following code:
--------------------------

What you placed in your qt.tmpl file is what is in my template
file as well .... it's simple a .tmpl file with the content of
what goes into the body of an email message. We have set things up this
way so non-code people could revise the email output
without touching the actual script file. Again, the template
file is a "bare" text file with a .tmpl extension .... no
variables/loops involved - simply there for non-programmers
to access.

Probably the most salient issue is the fact that the output
of these templates has been fine for a long time (some
well over a year, with no changes to the template file
during that time), and just last week the line breaks "doubled up".
My instincts tell me that this points to some sort of system
change, but again, we're pretty confident there has been no
changes at the system level, so I'm not sure what can be
causing this event. It's really got me baffled, and about the only
common denominator I can find is that the problem only occurs
in email messages where the body of the message is called at
the script level using HTML Template. Print statements to the
email body within the script don't display this problem. It really makes
no sense, but it's happening, and I'm the one that's got to fix it. And
of course when I tell others that I don't have any clue what-so-ever, they
kinda look at me like I must be off my medication ....

Well, I'm a bit confused.  The above doesn't look like a template file, so
I'm
not sure I'm actually answering your question, but I tried a couple of
things.

1.  I put the above <template></template> lines in a file named qt.tmpl,
and ran the following code:

     1  #!/usr/local/bin/perl
     2
     3  use strict;
     4  use warnings;
     5  use HTML::Template;
     6
     7  my $template = HTML::Template->new( filename => "qt.tmpl" );
     8  my $stuff = $template->output;
     9  print $stuff;

I got the following output:

##########################################
=> this represents line 1
=> this represents line 2
=> this represents line 3
=> this represents line 4
=> this represents line 5
##########################################

(Question: is that *really* your template file contents?)


2. The problem you describe reminds me of the classic beef about
extra line breaks when a template is filled in.  Of course, these
aren't really *extra*, because the template file contains them.  For
example, when I run the following code:

     1  #!/usr/local/bin/perl
     2
     3  use strict;
     4  use warnings;
     5  use HTML::Template;
     6
     7  my @array = <DATA>;
     8  my $template = HTML::Template->new( arrayref => \@array );
     9  $template->param( loop => [
    10      {line => "line1"},
    11      {line => "line2"},
    12      {line => "line3"},
    13      ] );
    14  my $stuff = $template->output;
    15  print $stuff;
    16
    17  __DATA__
    18  ##########################################
    19  <TMPL_LOOP name="loop">
    20  <TMPL_VAR name="line">
    21  </TMPL_LOOP>
    22  ##########################################

I get the following output:

##########################################

line1

line2

line3

##########################################

A template novice might complain that HTML::Template is adding extra
line breaks, but of course, they are right there in the template.  I don't
think that you're a template novice, so again I'm not sure this is answering
your question.

You say that nothing in your templates has changed.  However,
I don't think you have given a real example of one of these templates,
so beyond my guesses above, it's hard for me to know what will help.

[htmltmpl] Response to double line break thread

[C H. <hag...@ep...>]

Regarding my earlier question about the appearance of
"double" line breaks where previously there was one,
and the response by Alex:

<comment>
My two guesses (I havn't tried any code):

- the template file contains both \n and \r courtesy of your text editor and
perhaps unbeknownst to you. The \r is getting expanded to an extra \n. Run the
template file through unix2dos or an equivalent command to eliminate the extra
line endings.

- the association to $q you are using is changing things. Whats happens if you
don't use the association?
</comment>

One item worth of mention is that the double line break
problem I'm now seeing just recently started appearing
in template output (at least 30 templates ... maybe more)
that hasn't changed or been revised in some cases for
over a year. I'm also fairly confident that there
were no system changes recently. The behavior points
to some sort of systems event, but again, nothing has
changed at the system level. Since this is a vexing problem,
I was hoping there might be list members who have run
across a similar event.

[htmltmpl] Template output for email scripts adding extra line breaks

[C H. <hag...@ep...>]

I've recently encountered a very strange issue that appears
to be related to HTML::Template

I have many scripts at my site that generate email
messages, and I've noticed that the ones that
use HTML::Template to generate the body of the
message have recently been coming through with
"doubled up" line break. In other words, message
content that was formerly single spaced is now
double spaced.

I've tested this by creating a script with various
approaches to generating the email message content,
and the only portion of the content that exhibits this
extra line break behavior is the portion that
is run through HTML::Template.

Has anyone else experienced this issue, and if
so, figured out the cause?

Any thoughts on what might cause such behavior?
We're running Apache/Perl on a Linux RedHat system

This script code:
<code>
print MAIL "####### DIRECTLY QUOTED PRINT STATEMENT ##\n";
print MAIL "Single spaced lines between hash marks\n";
print MAIL "=> this represents line 1\n";
print MAIL "=> this represents line 2\n";
print MAIL "=> this represents line 3\n";
print MAIL "=> this represents line 4\n";
print MAIL "=> this represents line 5\n";
print MAIL "####### DIRECTLY QUOTED PRINT STATEMENT ##\n";
</code>

comes through as:

<output>
##########################################
Single spaced lines between hash marks
=> this represents line 1
=> this represents line 2
=> this represents line 3
=> this represents line 4
=> this represents line 5
##########################################
</output>

This script code:

<code>
my $stuff =
"######## HTML TEMPLATE ###################\n";
"=> this represents line 1\n";
"=> this represents line 2\n";
"=> this represents line 3\n";
"=> this represents line 4\n";
"=> this represents line 5\n";
"######## HTML TEMPLATE ###################\n";
;
my $template = HTML::Template->new(
         filename => "$tmpl_dir/CH_line_break_test.tmpl",
         associate => $q,
);
$stuff = $template->output;

print MAIL $stuff;
</code>

comes through as:

<output>
##########################################

=> this represents line 1

=> this represents line 2

=> this represents line 3

=> this represents line 4

=> this represents line 5

##########################################
</output>

Thank you (and Jason) for your prompt response.

I was thinking the same, but was reluctant since it makes the code a bit =
untidy.

Thanks again,
Nishi

Re: [htmltmpl] dynamic <tmpl_include>

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

The way I would do it is make two templates.  Instead of the 
tmpl_include, you would have something like

<tmpl_var name="subcontent">

Then in your code, you would create a 'fragment' template object based 
on the myDir/my.tmpl and then pass that template object output() into 
your parent template as the 'subcontent' parameter.

HTH,

Change your code to open the other template and paste its output into the
template with a simple TMPL_VAR.

[htmltmpl] dynamic <tmpl_include>

[Kapoor, N. <nis...@xc...>]

Hello all,

I have a need to include a template based on a certain condition i.e., I =
would like to be able to do

            <tmpl_include "<tmpl_var myDir>/my.tmpl">

where I can set myDir. Browsing the archives suggests that this =
functionality is presently not available. Since there is a long list of =
possible values that myDir can assume, <tmpl_if><tmpl_else> is not a =
feasible option.

Any suggestions?

Thanks,
Nishi

[htmltmpl] die_on_missing_params

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

Hi list,

Sometime ago I posted a message regarding having an updated H::T which
had support for "die_on_missing_params" - a feature requested by Joshua
Ball.

As a side effect of a machine update, I have managed to loose the
patch... If Joshua is still on the list, could you please email me
updated module.

cheers,
Mathew Robertson

Re: [htmltmpl] Other modules...

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

I use a modified version of H::T that allows the TMPL_xxx syntax to grow
and which has support for dynamic loading of the escaping modules.  I
also tend to use some specific filters.

So "no, not H::T::A" or other modules, and "yes, some locally modified
stuff".

regards,
Mathew

Simple: HTML::Template is fine for small templates, but its syntax is =20=

far too verbose, and as I'm using TT2 in other places, I felt as re-=20
using its syntax here as well, hence the filter.


The other thing now is that I had forgot how debugging errors in HT =20
templates was painful.

[htmltmpl] global_vars and TMPL_LOOP bug

[<htm...@to...>]

(Tested with HTML::Template 2.8 and 2.9)

The following looks like a bug to me:

Program:
+++++++++++++++++++++++++++++++++++++++++++++++++
#!/usr/bin/perl -w
use HTML::Template;

my $template = <<EOF;
<TMPL_LOOP NAME=diff>
 <TMPL_LOOP NAME=Drop>first</TMPL_LOOP>
 <TMPL_LOOP NAME=Mapping >
  <TMPL_LOOP NAME=Drop>second</TMPL_LOOP>
 </TMPL_LOOP>
</TMPL_LOOP>
EOF

my $t = HTML::Template->new_scalar_ref(\$template, global_vars => 1);
$t->param
    (diff => [{
        # Drop => [{}],
        'Mapping' => [{}],
    }],);
print $t->output;
-------------------------------------------------

Gives as result:

+++++++++++++++++++++++++++++++++++++++++++++++++
HTML::Template->output() : fatal error in loop output : HTML::Template->output() : fatal error in loop output : HTML::Template::param() : attempt to set parameter 'drop' with a scalar - parameter is not a TMPL_VAR! at /usr/lib/perl5/site_perl/5.8.4/HTML/Template.pm line 2998
 at /usr/lib/perl5/site_perl/5.8.4/HTML/Template.pm line 2998
 at ./test.pl line 19
-------------------------------------------------

So the first TMPL_LOOP NAME=Drop somehow destroys the the working of the second
one. Removing either of these loops makes everything work. Also removing the
outer diff level in the template text and the params makes it work. Also 
removing global_vars => 1 makes this work

Uncommenting the 
# Drop => [{}],
line in the code makes the output be:

+++++++++++++++++++++++++++++++++++++++++++++++++

 first

  second


-------------------------------------------------

That is also wrong I think since the docs are quite clear that there isn't
supposed to be a "global_loops" implied by global_vars. Only "first" should
have printed.

$pperror_template is, or has gotten, undefined.

You can confirm this by replacing '$pperror_template' with
'$pperror_template || q{}' at which point you'll get an error complaining
about the blank (vs. undefined) filename.

[htmltmpl] Error - odd number of option parameters?

[Tom K. <to...@tc...>]

I'm getting the below server error.

HTML::Template->new() called with odd number of option parameters - 
should be of the form option => value at 11102post.pl line 468

Line 468 reads:
    my $template = HTML::Template->new(filename => $pperror_template);

An earlier instance calling HTML::Template in the same file works 
fine. The error occurs when try to use it later in the script and 
causes the same error even when I copy and paste the earlier working 
code. My guess is that something other than calling the module is 
causing the error but I'm at a loss as to what to look for. If I 
remove the code block below, all works OK including the earlier use 
of Template. Any ideas where to look?

Tom

			_wemail      => $post_error_wemail,

[htmltmpl] Useful little patch for force_untaint option

[Sven N. <sve...@sv...>]

Hello,

this little patch will reveal the parameter name of the tainted value in
some cases. I haven't figured out how to do it in the other cases, I don't
think the name of the parameter name is preserved in the data structure.

Re: [htmltmpl] Filter Syntax

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

Hi Chris, I don't think anyone has answered yet...

The purpose of a filter is simply to modify the template-text-blob, 
before being compiled into its internal form, ie: the only thing passed 
into your filter, is the template.  Here is a simple/common filter:

    my $filter = sub {
      my $text_ref = shift;
      my $match = qr/%([-\w\/\.+]+)%/;
      $$text_ref =~ s/$match/<TMPL_VAR NAME="$1">/g;
    };

This filter replaces %some_var% with <TMPL_VAR some_var>.  Notice that 
the sub is called with only a text-ref.

 >From your example below, it looks like you are initialising the sub => 
... the result of the function call to initialize_template_header().  
What does this function return? for this syntax to work, it will need to 
return a sub-ref.

To answer your last question, you need to make use of "use vars ..." to 
stash your H::T reference in, eg:

{
  ...
  use vars qw($HT);
  $HT = H::T->new(... filter => some_filter );
  ...
  $HT->output();
}

sub some_filter {
  my $textref = shift;
  use vars qw($HT);
  ... access $HT ...
  ... modify $$textref or something...
}

But I'm not sure why you need to access H::T from within your filter.  I 
suspect that you are trying to something with filters, that it simply 
wont do -> I might be able to suggest an alternative solution if I know 
what the problem was.

cheers,
Mathew Robertson
