Item8071: stand-alone html -> tml conversion broken

From TWikibug:Item6152:

I have a lot of very simple HTML to import.

tools/html2tml.pl script is advertised (http://twiki.org/cgi-bin/view/TWiki/WysiwygPlugin) "Using the translators from perl scripts" as being capable of stand-alone html to tml conversion. I always get an error "Can't call method "getPreferencesValue" on an undefined value"

The built-in wysiwyg editor (4.2.3) works. So it's something about the stand-alone environment. I haven't done anything to/for/about the "WYSIWYGPLUGIN_STICKYBITS" variable that's in the traceback that I obtained.

This seems like a bug -- though perhaps the terse 1 line in the documentation is missing some setup requirements.

How, exactly, is one supposed to set things up for stand-alone conversions?

Example:

cd tools/

./html2tml.pl /temp/foo.htm
Can't call method "getPreferencesValue" on an undefined value at /var/www/servers/twiki/lib/TWiki/Func.pm line 474, <> chunk 1.

Here is a sufficient example with traceback. For the purposes of the example, the script is reading from stdin - I pasted the text with ^d after hitting 'c' in the debugger. The traceback is identical when run from a file. (And when run with a complete html page.)

cd tools/
perl -d ./html2tml.pl

Confirm there's a problem with the convertor. The global session variable isn't set when getPreferencesValue is called.

-- CrawfordCurrie - 04 Mar 2009

Not a release blocker for 1.0.3

-- KennethLavrsen - 05 Mar 2009

This works now, in 1.1, so I'm changing the state to "no action required".

-- MichaelTempest - 30 Jul 2009

Replaced references to images on my server, which isn't accessible, with the corresponding images from foswiki.org. This will fix errors viewing page - and errors on my webserver.
