Question

The attached math-mode-symbols-overview-removed-spaces.txt sample page does not get rendered correctly by MathModePlugin (images appear "rotated", i.e. the wrong image gets used for the wrong formula)

The formulas are assigned to the wrong images. I've been digging through the code but couldn't find anything useful.

Answer

If you answer a question - or someone answered one of your questions - please remember to edit the page and set the status to answered. The status selector is below the edit box.

Don't use spaces after %$ resp. before $% then your symbol overview table will work, if you have closed all table cells correctly.

Hi, I removed all spaces after %$ resp. before $% as FranzJosefSilli suggested, still all images are assigned to the wrong formulas. I'm using this overview page to enable my team to get started fast with formula editing; if anybody knows how to fix this; it will be greatly appreciated.

Hm, can you provide your updated math-mode-symbols-overview.txt so I can test it at my local installation? -- Good idea to provide such an overview to your users.

I guess it's just a matter of properly closing all the table cells, this can be pretty tricky. Mind that every row has to consist of an equal number of columns, otherwise TWikis table notation gets easily confused. Maybe that's what is causing your mixup.

Hint:

I made this a support topic cause it isn't about the development of the plugin source itself. Hope that's okay with you.

I have uploaded the new file. Thanks Franz for your help with my problems. Note that I fixed almost all of the page by adding the formulas incrementally. The only table that is broken for me is the last one; I added one table at a time this time. This suggests that there is a hash-clash when having many (>200) short formulas in one page.

I tried to rewrite the plugin to use HTML::Parse to parse the html file created by latex2html instead of just expecting the images to have the correct number, however I couldn't get it to work correctly. I'll upload the edited version of MathModePlugin, perhaps you can make it work?

FranzJosefSilli, I have also created an overview for using the DirectedGraphPlugin, I can post it if you want to use it.

-- MikaelOlenfalk - 09 Aug 2005

Yes, please post th overview in DirectedGraphPluginDev. Every enhancement (or enhancement proposal) of a TWikiExtension should be posted in the corresponding development (Dev) topic so that others (or the plugin maintainer (author)) can take over the enhancement into a new release (more easily). Your overview topics should be bundled with the particular plugins, cause they are very useful pieces of documentation.

Please note that there are formatting errors in the attached txt file, being unnecessary $^b$ strings (look at the Join and sqsubset declarations). I've uploaded a version where I removed erroneous $^b$ entries in the tables and that rendered just fine. I'm changing the status to AnsweredQuestions. I this fix doesn't work for you, please change it back.

By the way, thank you for the work on the table, this is very useful!

I believe the "rotation" problem reported on the last table in this example file is caused by a mismatch between the (internal) MathModePlugin hash table and the latex2html hash table. You might give the LatexModePlugin a try, which fixes this bug.
