There's a file called dvips in my minimals-context/tex/ temf-osx-intel/bin/ It seems to be dated 9/17/07 The version of pdftex is newer than the patched one: July 22 2009 vs. March 31 2009. I'm going to assume it's OK. Taco Hoekwater wrote: >> >> Question: is this still a problem for luatex 0.44?

And it's not just pdftex, apparently. They say that luatex is affected too. That's primarily what I use. So we have both known symptoms (sort of - they're vague) and an allegedly known cause. Perhaps we have a diagnosis. Here is Dick Koch, "A Fix for the Corrupt Font Cache Bug" http://www.tug.org/mactex/fontcache/Font-Cache-Bugfix.pdf > The “corrupt font cache bug” on OS X has been traced by Melissa > O’Neill to a bug in pdftex, present in that program since 2004. > The incorrect code is also used in other programs, notably dvips, > luatex, and metapost. … > > The code containing the pdftex bug was used with little change in > modern versions of dvips, so ﬁxing the bug in dvips was not > diﬃcult.

This should ﬁx the bug for most users. Notice that pdftex > is used when typesetting in “pdftex” mode and dvips is used when > typesetting in “TeX and DVI” mode. XeTeX does not have the bug. And in another document, "Looking over the Debugger’s Shoulders ", Koch summarizes what they discovered this way: http://www.tug.org/mactex/fontcache/Debugging.pdf > Two bugs contributed to the problem. First, pdftex, dvips, luatex, > and metapost were not correctly subsetting certain fonts. And > second, a large number of fonts contained subroutines which did not > conclude with a RETURN command. Many of these were created with the > utility mmpfb, which has been patched. Question: is this still a problem for luatex 0.44? (Please say no). If not, perhaps I should clean my caches and use only MkII/XeTeX. Even then, I gather that old documents created with luatex will still be little time bombs (see Appendix, below). I guess I have to delete all pdfs made by luatex and regenerate them as needed. That's a lot of documents. "Nasty" is right. Oy. mjg Appendix: Koch's explanation of why the font cache might become corrupt seemingly for no reason at all. http://www.tug.org/mactex/fontcache/Font-Cache-Bugfix.pdf > When GUI programs display pdf ﬁles, they call Apple’s internal > pdf routines.

Specifically, they patched the binary files dvips and pdftex Have these patches been applied to the versions of dvips and pdftex in the minimals? If not, is there any reason why I shouldn't substitute these patched versions for the ones in the minimals? Thanks. mjg Source for the patch: http://www.tug.org/mactex/fontcache/ http://www.tug.org/mactex/fontcache/patchedbinaries.tar.gz

Hello, how can I add a label and a caption to a table? I guess that the label is \starttable[|l|l|l|l|l|l|l|l|][MyLabel] But what about the caption? I have been looking in http://wiki.contextgarden.net/Table Thanks a lot for the help... Cheers, Pau

The very next document I prepared had the same boxes-rather-than-letters problem. That said, I cleared the font caches again and, after restarting, the document looked correct. Perhaps this is a coincidence. Or perhaps there is something amiss with the way my computers are caching fonts. Sigh.

Incorporating svg images in Context.

A 2007 post from HH suggests the following: -------------------- \usemodule[res-08] \setups[rl:manipulate] \setupexternalfigures[conversion=pdf] \starttext \externalfigure[system.svg] \stoptext --------------------- There is a module x-res-08.tex on my system.
