I've used it for:

PostScript (mostly for parameter insertion)
.ini files
plain text (that gets fiddly with line breaks)
source code formatting
...oh, and HTML.

Some people like Template::Toolkit, especially on London.pm, but I
prefer a more lightweight package.

"comfortable with... make" is the last description that would fit me - I
can install from source using "./config ; make; make install" but that's
about it for me, so it does not look like I'll be giving webmake a spin.
Thanks for the reply, though.

it certainly can be done, and i suppose "suitability" is best judged by you,
after using it that way.  it's quite suitable (for me) for generating static
files, but that may just be because i use it so heavily for CGI scripts that
i've become very familiar with the syntax, and comfortable using it in other
ways.  having said that, i *don't* usually use it to generate static *HTML*
files, but mostly for other things such as conf files and other
miscellaneous system administration work, and this is definitely *not* it's
stated purpose.

i've flirted on an off with using webmake: http://webmake.taint.org/

it is however "yet another templating system", with it's own syntax and i've
been reluctant to switch (maybe my comfort level with H::T has become a
liability :-)) but webmake's design is very clearly aimed at generating (and
maintaining) web sites as sets of static html files so ...especially if
you're comfortable with the process of building and compiling software with
make, makefiles and the like, webmake may be just what you're looking for.

if you do decide to use webmake, please post back here with your impressions
(good or bad).  i come across web dev projects often enough where a sizeable
site of static pages needs to be generated (and only occasionally
regenerated), based on smaller set of "core templates".  in these certain
situations, though i usually end up using a dynamic templating system
anyway, it does sometimes feel like overkill, which is why i've been keeping
an eye on webmake.

Hi,

HTML::Template is *definitely* suitable for this task, too.

CGI::Application::Generator uses it to create stubs in a perl module
file, and I have heard rumors that people use HTML::Template for
Postscript or Pdf generation - so generating static html pages should
be something really straightforward with HTML::Template.

By the way, CGI::Application is really worth trying for any CGI with
more than one state, especially together with HTML::Template.

[htmltmpl] using HTML::Template to generate static web pages

[Offer K. <of...@ne...>]

Hi,
I'm an HTML::Template newbie, and I was wondering whether the veterans
on this list could help me.

The documentation for HTML::Template talks about using it as a CGI
script, to generate the HTML code "on-the-fly".
However, I would like to use it as a regular Perl script, to generate
static HTML pages. I know this *can* be done, since I tried it on the
example provided in the documentation. But I'm wondering whether
HTML::Template is really suitable for this kind of use, or if I'm
"abusing" it.

Is there another module you could recommend as better suited for this
task?
I've looked at the Template-Toolkit, but it looks a little more complex
than HTML::Template, so before I choose it or another module over
HTML::Template I would appreciate some advice from veteran users.

Thanks in advance,
Offer Kaye

[htmltmpl] list_unfilled_vars

[Wayne W. <ww...@by...>]

I need something roughly opposite die_on_bad_params.  I need to know
what vars (or loops) in the template are NOT populated at output time.

I've taken over a project where I need to know if I am completely
populating the templates.

Any ideas?  I could do a bunch of query looping and call param('name')
on all the vars that query gives me, but it seems like I wouldn't be the
first to want this.  Is there something already written?

Thanks!

[htmltmpl] ANNOUNCE: Bricolage 1.6.6

[David W. <da...@ki...>]

I'm pleased to announce announce the release of Bricolage 1.6.6.
This maintenance release addresses a number issues discovered since
the release of version 1.6.5. Some of the more important changes
include:

     *   Added README.Solaris.

     *   When an asset is published or deployed directly from the asset
         profile, it is now properly removed from the publish or deploy 
desk.

     *   Templates now display their output channel associations instead 
of
         their element associations on desks. This seems to be more 
useful,
         since the element association is usually obvious from the name.

     *   The category URI is now displayed for assets on desks, rather 
than
         the name. This is consistent with the display of the category
         elsewhere.

     *   Elements to which no subelements can be added will no longer 
display
         an empty select list and "Add Element" button.

     *   Bug fix when deploying to multiple output channels. If the 
output
         channel IDs matched each other partly, it could cause a file to 
be
         removed after it just had been uploaded.

     *   Users with CREATE access to a start desk can once again create
         stories on that desk even when they don't have CREATE access to 
"All
         Stories."

     *   Each upgrade script is now run within the confines of a single
         database transaction. If any database changes within an upgrade
         script encounter an error, all of the changes in that script 
will be
         rolled back.

     *   An upgrade script failure will now cause "make upgrade" to halt
         installation so that any issues are immediately identified and
         correctable.

For a complete list of the changes, see the changes file at:

   http://sourceforge.net/project/shownotes.php?release_id=188766

One way to see a real improvement is to load all your templates during
Apache startup.  Then the memory used by the templates will be shared
across Apache child processes.  For large apps with lots of templates
this can save quite a lot of memory.  You'll find an example of
loading templates at startup in the FAQ section.  For details about
Apache and shared memory in child processes see the mod_perl guide on
perl.apache.org.

[htmltmpl] Q: Template caching and mod_perl

[Todd C. <htm...@ch...>]

I am moving my CGI script to mod_perl. To get things
going quickly I'm running them under Apache::PerlRun.
The HTML::Template docs say that I can turn caching
on when running under mod_perl. Does this assume I
am using Apache::Registry, or will the caching work
with Apache::PerlRun also?

Thanks!

[htmltmpl] nested loops

If I understand this right ... I click a link in "map", it changes both
"map" and "table" and blanks out "tabledetail". If that's right, the
following solution will work for you.


1.) In your map frame, create your links like this:

<a  href="table.cgi"
    onClick="window.self.location='map.cgi'"
    target="table">

    My Map Link

</a> 

Note the the HREF fills the "table" frame and the onClick fills the current
frame. 

2.) In the SRC of the table.tmpl file, include a lil bit of javascript
magic. Something like this (the actual syntax here may be incorrect)

top.tabledetail.document = "blank.html";

Put that right after yer script tag, with no subroutine around it so it will
fire as soon as the browser reads it.


And you're done.

Thanks for the replies folks. Really appreciate it. However, I _need_ 
to use frames because... well, I need to. I am not a big fan of frames, 
and know most all the ways to avoid them (or fake them... overflow:auto 
is great). However, I also believe that frames can be immensely useful 
in certain situations, and this is one of 'em.

POST requests usually cache-out, and db queries are expensive. In this 
application, frames not only simplify navigation, they also minimize 
user-webserver as well as webserver-dbserver traffic.

As I described earlier, I have four frames like so (we can forget about 
the header frame) --

header.cgi      --> header.tmpl      --> frame: header
map.cgi         --> map.tmpl         --> frame: map
table.cgi       --> table.tmpl       --> frame: table
tabledetail.cgi --> tabledetail.tmpl --> frame: tabledetail

clicking on the map (in the map frame, obviously), causes map.cgi to 
select certain features in the map and redraw the map with those 
features selected. Those features are also connected to a dbf file (and 
later on, to a real table in MySQL). Hence, the dbf rows are also 
selected. However, the map gets redrawn via the map.tmpl in the map 
frame, while the dbf rows need to be shown in the table frame. The way 
I am doing it right now is that I show the map in the map frame, and 
then a form button with a lame message such as "12 features selected -- 
press button to view them". Pressing the button calls table.cgi with 
target="table", and the dbf rows are displayed in the table frame. Then 
clicking on any single row shows its details in the tabledetail frame.

Ideally, I would like map.cgi to select the features in the map, redraw 
the map, and send the map to the map frame, and the dbf rows to the 
table frame. In case the table frame or the tabledetail frame have 
query results from a previous call, I would also like to send a 
blank.html to them, etc.

Drawing the map and querying the dbf file (or the MySQL table, later 
on) is a fairly expensive proposition (esp drawing the map), so frames 
allow me to have the user navigate only parts of the application 
desktop without refreshing things unnecessarily.

Would be nice if I could somehow tell a template to go to a specific 
frame, of course, filling a frame is a pulling action, so there is no 
way to send a template to a specific frame. I am coming to the 
conclusion that I cannot do what I want, and will have to devise some 
other approach to this app.

Puneet.

Ah.

It's still sort of do-able, depending on your reason for frames.  If
they're just there to, say, provide scrollbars and you don't mind
refreshing the whole page, you can do something like this:

Button launches script into _top.  Script builds all the frames, writes
them out (either as complete HTML files or as parms to be stuffed in
H::T later) to something persistent, then returns the top-level HTML to
the browser.  That top-level HTML either refers to files that were just
written, or to a subsidiary script that just populates templates.  (In the
former case, you have to worry about expiring old files and handling
404's; in the latter you just have to worry about expiring old data, and
the subsidiary script can gracefully handle references to data it can't
find.)

It's not quite as pretty as just refreshing two frames, but I can't think
of any other way to do it.  Depending on the structure of your page, you
might be able to make the frames that need refreshed a nested framed page,
though.

ya but...

see, the problem is not really being able to fire two frames (yes, js 
is the solution)... the problem is firing them from one perl script 
calculating/creating values that have to be displayed in two frames... 
as I understand... one script usually has one template associated with 
it (although it could have more templates... there is nothing in the 
docs that says it can't). What I cannot to is fire two scripts... 
because all the relevant calculations are in one script... I just want

this may well prove my undoing.

Only way I know of to do that is with Javascript and putting an onclick
either in the FORM or in the A link (depending on whether your "button"
is a submit button or just a link button).

Here's one explanation:

http://www.experts-exchange.com/Web/Web_Languages/HTML/Q_20737567.html

(The problem is, of course, those of us who use non-Javascript browsers
will only get one frame updated.  Of course, my non-JS browser is also a
non-framed browser, so I suppose it's a moot point...)

[htmltmpl] firing multiple templates

[Puneet K. <pk...@ei...>]

So I am working with frames (I have to). Different scripts populate 
different templates in different frames -- at different times. Now I 
want to press one button in one frame, and update two (or more) frames 
with respectively different templates.

I have --

frame1.cgi --> frame1.tmpl --> frame1
frame2.cgi --> frame2.tmpl --> frame2
frame3.cgi --> frame3.tmpl --> frame3
frame4.cgi --> frame4.tmpl --> frame4

I want to do --

frame1
frame2
frame3 --> frame3.cgi --> frame3.tmpl --> frame3
                       |
frame4                |-> frame4.tmpl --> frame4


Needless to say... there is stuff in frame3.cgi that is powering stuff 
in frame3.tmpl as well as in frame4.tmpl.

(
I am clicking on a map in one frame which is causing features to be 
selected and the map to be redrawn with the selection visible. At the 
same time, I want to query the underlying database for the selected 
features and display them in another frame.
)

How do I do this?

[htmltmpl] Dynamic and sticky forms

[Wojciech P. <W.P...@it...>]

Hi,

I have a form that collects info about books' authors.=20
There is a popup menu idicating the number of authors=20
and dynamic number of text fields for the authors' names.

Here you are (simplified example):

<-- how many authors -->
<select name=3D"nr_of_authors" onChange=3Dsubmit()>
<option  value=3D"1">1</option>
<option  value=3D"2" selected>2</option>
<option  value=3D"3">3</option>
</select>

<-- create fields for authors -->
<form>
<input type=3D"text" name=3D"author_1" value=3D""><br>
<input type=3D"text" name=3D"author_2" value=3D""><br>
<form>

This is a part of authors.tmpl:
<TMPL_LOOP NAME=3D"aut_loop">
    <input type=3D"text" name=3Dauthor_<TMPL_VAR NAME=3D"__counter__"> va=
lue=3D"?"><br>
</TMPL_LOOP>

Does anybody know how I can make that formy sticky and take advantage of
associate function? What should I put in the place of question mark? It
looks like <TMPL_VAR NAME=3D"author_<TMPL_VAR NAME=3D"__counter__">"> doe=
s not
work.

Thank you in advance.

I see Karen has given you some ideas.

To create a crude tree-like structure within a table, try=
 prefixing 
the rows with multiple white boxes and then an 'elbow' box.
Demo images:
http://www.deakin.edu.au/~rons/html/black-and-white-boxes.html
This method is trivial, but may help.

Also, learn how to use H::T's __first__ etc tokens to change the=
 CSS 
class of a <td>, etc. Demo:
=09<tmpl_loop name =3D outer_result_loop>
=09=09<tmpl_if name =3D __first__>
=09=09=09<tr>
=09=09=09=09<tmpl_loop name =3D inner_result_loop>
=09=09=09=09=09<td class =3D "headbox">
=09=09=09=09=09=09<tmpl_var name =3D result_td>
=09=09=09=09=09</td>
=09=09=09=09</tmpl_loop>
=09=09=09</tr>
=09=09<tmpl_else>
=09=09=09<tr>
=09=09=09=09<tmpl_loop name =3D inner_result_loop>
=09=09=09=09=09<td>

=09=09=09=09=09</td>
=09=09=09=09</tmpl_loop>
=09=09=09</tr>
=09=09</tmpl_if>
=09</tmpl_loop>

No there isn't.  But it should be easy to create your own __counter__
workalike and access it normally with global_vars set.

H::T doesn't recurse very well, but it does loops nicely.  What I end up
doing is putting all messages in a single TMPL_LOOP.  The indentation
level is then used to make a dummy TMPL_LOOP within that one, which is
used by the template however it needs to be... at the moment, I think I'm
just using nonbreaking spaces to indent it.  You could use clear graphics
to do the same thing.

If you were willing to accept less of a separation between template and
code, you could pass a simple variable instead (level*N), and use it for
the width of a clear graphic, or an empty table cell.  Or if you're using
expressions, you could pass the level value as is, and multiply it by the
desired amount within the template.

First, the part that isn't your question, but I feel opinionated :)
Recursion is expensive.  I've done this in two other ways, depending on
my data:

1) Select all data from table (including info on which nodes are
children of others, then sort.)

2) create a list (initially of just the root).  Move through this list,
inserting (splice()ing) any children of the current node just after the
current node.  This is my preferred method.  IT also allows me to store
the "depth" (relative to root) of each node.

I just offer my data as a list to my template, which can then style the
output based on the depth of the node (since that is now in the data).
For example, each node usually has (NodeID, Depth, Name, Title, Text,
Date).  I can indent or otherwise indicate the depth on a per-row basis,
and all HTML formatting is done in the template.

Hope that helps in some fashion.
