iwpt_compile made my day. Not!

Howdy.

I've created a Perl file (say, $iwhome\local\bin\shared.ipl) with some commonly shared code between presentation templates.

When compiling a presentation template (on a Windows 2000 machine running TST 5.5.2 w/ SP2) that "requires" shared.ipl, I'm getting:

Use of uninitialized value at (eval 17) line 31.
Use of uninitialized value at (eval 17) line 49.

Which file are those line numbers in?

And I'm getting:

Undefined subroutine &TeamSite: Smiley Tongue

T:lithiumiw_xml_generated_0::iwpt_dcr_value called at d:\iw-home\local\bin\\shared.ipl line 145.

I have this in shared.ipl, inside a subroutine:

$registrydcr = iwpt_load_dcr("\\templatedata\\components\\PC000_Jobs\\data\\job1","docroot","t");
$department_name = iwpt_dcr_value('registrydcr.department');

Interestingly, the iwpt_load_dcr routine seems to work alright.

I don't have any "use" or "package" directives at the top of shared.ipl. Should I?

When running iwgen, I'm getting:

Use of uninitialized value at (eval 52) line 49.
Error: NextExtAttr failed
Error: NextExtAttr failed
Could not process template: ...\overview_departments.tpl

Help!

Thanks,

S.

Backup IWHOME/bin/iwpt_compile.ipl. Then add these lines right before it calls main():

if ( ! open( LOG, ">>${some_temp_file}" ))
{
die( "Unable to open ${some_temp_file} for write : $!" );
}
else
{
print LOG "@ARGV\n";
close( LOG );
}

Regenerate your page, then the last line in the log file will indicate the parameters that were passed to iwpt_compile.ipl when the presentation template you are working with was executed, for instance (assuming NT):

-umask 0113 -pt Y:\default\main\Project\WORKAREA\teamsite\templatedata\Intranet\Metadata\presentation\DocIndex.tpl -smartwrite -iw_pt-preview -ofile Y:\default\main\Project\WORKAREA\teamsite\templatedata\previews\preview.html -iw_include-location Y:\default\main\Project\WORKAREA\teamsite -osenc CP1252 -manifest Y:\default\main\Project\WORKAREA\teamsite\zz_tst_westjohn_0_manifest -oprefix zz_tst_westjohn_0_ -iw_pt-dcr Y:\default\main\Project\WORKAREA\teamsite\templatedata\Intranet\Metadata\data\docs\CM_11Dec02_Demo_Report.doc

Log in to the TeamSite server and execute iwpt_compile.ipl with these parameters (all on one line), such as:

c:\iw-home\iw-perl\bin\iwperl c:\iw-home\bin\iwpt_compile.ipl

-umask 0113 -pt Y:\default\main\Project\WORKAREA\teamsite\templatedata\Intranet\Metadata\presentation\DocIndex.tpl -smartwrite -iw_pt-preview -ofile Y:\default\main\Project\WORKAREA\teamsite\templatedata\previews\preview.html -iw_include-location Y:\default\main\Project\WORKAREA\teamsite -osenc CP1252 -manifest Y:\default\main\Project\WORKAREA\teamsite\zz_tst_westjohn_0_manifest -oprefix zz_tst_westjohn_0_ -iw_pt-dcr Y:\default\main\Project\WORKAREA\teamsite\templatedata\Intranet\Metadata\data\docs\CM_11Dec02_Demo_Report.doc

-ocode c:\iw-temp\tempscript.ipl

c:\iw-temp\tempscript.ipl will contain the Perl script that TeamSite uses to generate the output of the presentation template. So run c:\iw-temp\tempscript.ipl and the error messages should give you accurate line numbers, which you then have to map back to lines in your presentation template, modules, etc.

Hi,

I'm on Solaris, so this method might not work for you, but when I see something related to templating about "blah on line 123" it usually refers to the in-memory perl code that results from iwpt_compile.

You can capture what TeamSite does by running the iwpt_compile command on the shell and using the "-ocode test.ipl" flag in your command line.

For example, imagine that you wanted to compile some TPL and spit out the results to some html page, but wanted to find out *how* TeamSite was doing that. Run something like this:

iwpt_compile.ipl -pt path-to-tpl -ofile path-to-html -ocode /tmp/test.ipl

Running this will show you and compile errors TeamSite has. If there aren't any serious ones, then running the /tmp/test.ipl will show you any run-time errors that happen.

Having said all that, I wouldn't worry too much about 'Use of unititalized values" in Perl. . . . . those are usually completely harmless.

On the other issue of 'Use of undefined subroutine', I bet that the iwpt_load_dcr isn't working. Try commenting out your iwpt_dcr_value line and you'll probably get an error about your load_dcr line.

So, a couple things to check: are you using iw-perl in your first line ( #!__IWHOME__/iw-perl/bin/perl ) ? Or is this just a standalone library file you're including ?

Also-- while I'm not sure of the scoping rules on these kinds of things -- I imagine that you'd have to have some sort of "use lib " statement referencing your IWPERL lib and then a "use TeamSite::Templating" line in your code. Maybe someone with more perl know-how can chime in . . .

Thanks much to you and John for your helpful tips.

For the moment, I just moved the subroutine with the iwpt_dcr_value from a separate IPL file into my TPL file.

You're probably right that I need to "use lib." I've never done that before : ).

Thanks and regards,

S.

If you use the IWOV perl

meaning #!/IWHOME/iw-perl/bin/iwperl

you will have the correct libs set for TeamSite modules.

You should always use the IWOV version.
