Question

%CALENDARPLUGIN% produces no HTML at all. Nothing in the error logs. I've installed all the dependency modules and they work fine. Other plugins work fine. Tried it on the stable & beta releases. Running on Fedora Core 4 with perl 5.8.6. Downloaded the latest testenv & everything seems fine:

• testenv-output: output of testenv
• TWiki.cfg: my twiki.cfg

Works OK for me on RHAS3 at work!

I've set debug=1 in the CalendarPlugin module - nothing. I've got the modules installed (via CPAN and this is where they ended up:

/usr/lib/perl5/site_perl/5.8.6/i386-linux-thread-multi/Date/Calc.pm
/usr/lib/perl5/site_perl/5.8.6/HTML/CalendarMonthSimple.pm

Have you tried installing the latest version of Cairo then adding CalendarPlugin?

-- SteveRJones - 11 Oct 2005

TWikiBetaRelease2004x10x30 is not based on Dakar codebase.

Things to check:

• Plugins can be disabled selectively in the TWikiPreferences
• A Plugin might not load at all if there is a compile error. It might not even show an error message. Do a compile check (perl -c CalendarPlugin.pm).

-- PeterThoeny - 11 Oct 2005

I have not tested it extensively but have confirmed that CalendarPlugin does work in Dakar.

-- LynnwoodBrown - 11 Oct 2005

Oops, mea culpa, I completely misread the version number. My sincere apologies.

-- SteveRJones - 12 Oct 2005

What Peter refers to - running a compile check - is a cute trick that I should have mentioned. I've caught many problems this way prior to releasing a Plugin. I must not be getting enough sleep

-- SteveRJones - 12 Oct 2005

I'm not sure if this is relevent or not, but I notice some comments near the end of CalendarPluginUndefinedSubroutine that describe similar problems to what you're experiencing - and refers to some cryptic (at least to me) solution that involves changing ours to my somewhere.... Just thought I'd mention this as possible lead.

-- LynnwoodBrown - 12 Oct 2005

are you actually typing %CALENDARPLUGIN%? it should be %CALENDAR%

-- WillNorris - 12 Oct 2005

Sorry, %CALENDAR% is what I'm typing (my typo!). I tried perl -c, and that passes fine. I'm using the exact same version of twiki & calendarplugin as I have installed on RHEL3 at work, and there it works fine.

What's cairo when it's at home?

-- IlltudDaniel - 13 Oct 2005

Anybody? My perl's not bad, I could stick in extra debug stuff. It's just doing nothing, and it's functionality I'd really like. Otherwise I'm going to have to add some php groupware to the site & tack it on to the twiki somehow.

Lynnwood - my perl's 5.8.6, so that shouldn't be the problem I'm getting (and that error would show up in the logs).

-- IlltudDaniel - 14 Oct 2005

Plugin is definitely activated, I've tried Version: 04 Sep 2004 $Rev: 1742 as well, and that's exactly the same.

-- IlltudDaniel - 14 Oct 2005

Did you check if the two necessary perl packages can be accessed by TWiki? Put the package names in the optional perl package area of your testenv.

-- FranzJosefSilli - 14 Oct 2005

What does TWiki.InstalledPlugins say on your site?

-- MartinCleaver - 14 Oct 2005

See the Environment table above

-- IlltudDaniel - 14 Oct 2005

Franz - I'll try that.

-- IlltudDaniel - 14 Oct 2005

Franz - bingo, that's the problem. From testenv: Note: Optional module 'HTML::CalendarMonthSimple' not installed

Now I'm trying to work out why. Well, this is why:

[root@gwenno bin]# cd /usr/lib/perl5/site_perl/5.8.6/HTML/
[root@gwenno HTML]# ls -l
total 56
----------  1 root root 50668 Oct  6 23:53 CalendarMonthSimple.pm

Thanks for all your help, folks.

-- IlltudDaniel - 14 Oct 2005

You're mostly welcome. Would have been sad to switch to another system just for this. The CalendarPlugin is very useful for visualizing events. It's too bad that it's a performance killer and not well supported by its original developer.
