The PerlKB::Document object accepts a `type' argument on creation and tries to load the corresponding module. If it is successful, then it bless's the current document object (being created) into that class/module. I think DOS/Windows is presenting a case-insensitive filesystem and thus PerlKB::Document::pod loads, but is really PerlKB::Document::Pod. The PerlKB::Document code tries qw(pod POD Pod) in that order and stops with the first successful load. This is regardless of the capitalization of `type'. This was made this way to allow differences in actual and expected capitalization (e.g., qw(html HTML Html)). This side effect on case-insensitive filesystems should be viewed as a bug. I'll try and figure out a fix that can still be flexable enough to not require prior knowledge of modules (within PerlKB::Document) and allow for capitalization varients. If I can't think of a good way around this, I'll ditch it and require proper capitalization of the `type' parameter. --jim

Yes, I did add the changes you mentioned in the previous email althought I did not DL the new tarball. Let me try that... Interesting... I DL the newest taball.

Not sure. It should be able to see it. Can you give me the line number or any other context for it? Is it version 0.03 (the changes I mentioned in the previous e-mail)? Do you have Config::Pod located somewhere? It's needed for the PerlKB::Configuration::Pod module to work (and no, I don't have that documented that I know of, yet - sorry).

I will include a `require 5.006;' I do make use of `use base', the three argument form of `open' and auto-vivification of file handles in addition to `our'. Can't think of any others right now. --jim
Re: [Knowledge Base] First coherent release
I feel a little stupid now that I actually read up on tying hashes. Had I
read Ch 14 of the Camel #3, I might have phrased my question in a better
way so as to not illuminate my inexperience with tying variables. :-)
I assume that the reason I get the "Can't locate the render_format method"
is because you're not actually storing any objects yet?
One final question, by using "our" you're restricting these modules to perl
5.6.x. Is there any particular reason for this? From the looks of it, the
usage of our could easily be changed. Do you have plans to take advantage
of other 5.6 specific features? Either way it would be nice if you included
a "require 5.6.0;" in PerlKB.pm so that it would be immediately obvious to
the new user.

Re: [Knowledge Base] First coherent release
I've run into a WEIRD problem that I think is ActivePerl related. I've
installed the PerlKB modules and added some debugging code to
PerlKB::Store.pm. The short story is that I have to shift TWICE to get rid
of the "PerlKB::Store"! This is with the latest ActivePerl which I just
installed tonight. And to top it off, once the config href is populated I
get an "illegal operation" error and no result. :-( My system is Win98 SE.
Any ideas? This is just weird...

[Knowledge Base] First coherent release
I've put together a tarball of the PerlKB modules: http://prdownloads.sourceforge.net/perlkb/PerlKB-0.02.tar.gz The example/ directory has a little script that shows how the store objects work. The scripts/ directory has a perl script that starts up the PerlKB::Shell monitor (modeled in a small way after the CPAN shell). Otherwise, it doesn't do a whole lot, but it's starting to come together.
