[Ipe-discuss] Warning! Beware of grouped text

For long I have had problems with my ipe-files becoming unreadable and
never understood how to avoid it. Now I think I know how.
When I have text in a group and change fontsize of the group something
1. When I save and reopens it,Ipe says it does not recognize the the
symbolic attirbute footnote (if footnote is the size set to the
group). The file can still be opened and the problem fixed if the
group is selected and again the font size is set again, everything
2. Frequently when having a grop of text with the font changed, the file
becomes unreadable, i.e. can't be opened after save.
Both problems can be reporduced by:
a. Open Ipe
b. Make some text
c. Group it. (Can be done with a single textobject)
d. Set font size of the group to "footnote"
e. Save (preferrable as xml)
The second problem can be fixed by hand editing of the xml file. There
is a ">" character missing at line 7. You can insert it and open the
file in ipe. Then the first problem shows.
As long as you save the file in xml you are relatively safe, however if
the document would be in pdf or eps, fixing the problem is not trivial.
Therefore I think there should be a
*** Warning somewhere in the documentation or on the Ipe homepage. ***
Of course even better would be a patch.
To fix the problem with the corrupt file format, I have made a macro in
vim that runs through the file and corrects the content.
Add these lines to .vimrc
map qf ggqipe1
map qipe1 /<text\(\s\+\k*="[^"]*"\)*[^>[:blank:]]/e<CR>qipe2
map qipe2 i><Esc>qipe1
Then to use it, open the file in vim, hit the keys qf
Save and leave by ZZ
I know, not very elegant, I would have preffered to do it in sed or
perl, but my knowlede of those is too limited to make a fast fix.
