new MyWay about \sometxt
by Mojca Miklavec 08 Feb '07

08 Feb '07

Hello, instead of checking the problems with MyWay about database module, I created another unfinished piece about \sometxt (as promised already long ago): http://dl.contextgarden.net/myway/sometxt.pdf \sometxt{...} should be used instead of textext("...") in metafun graphics whenever possible, since it's much more efficient. An average user shouldn't care about much more than that. The MyWay is devoted to the curious ones. I hope that I included all the major ideas which Hans implemented in Summer/Autumn 2006 on my request. Although not all of them are documented well enough, I tried to mention them at least. The document is full of mistakes and badly formulated sentences (I should start reading more English literature instead of mailing lists and articles ;). I wellcome any suggestions for improving it. Thanks to Hans van der Meer who provided me the first feedback ;) Just two questions left for Hans H. (Hans v. d. M. has brought up exactly the same questions as I had a while ago): 1.) wouldn't it make sense to use \chardef\TeXtextcolormode\zerocount as the default value? I don't see any advantages of setting it to "one" (but I might have overseen something). Can you please take a look at page 4 of the above listed MyWay and tell me if I forgot something? 2.) Why does \textext still rely on its older brother textext(...), when it could be a synonym for \sometxt{...} instead? I really don't see any advantage of \textext{...} over \sometxt{...}. \textext{...} canonot be used for concatenating strings or creating dynamic labels either. It's just a picture, just as \sometxt ... And it would probably also be more straightforward to explain to metafun users that textext("...") should now be \textext{...} instead of trying to explain them that it's best to use some completely new command. Thanks a lot, Mojca

Debian Context Font problems
by Mike Bird 07 Feb '07

07 Feb '07

Hi Norbert, Here's a simple test case illustrative of the reason why I don't use Debian Context packages 2007.01.23-1 and 2007.01.23-2. \starttext \S1 \blank[big] \S2\crlf\S3 \stoptext In 2007.01.12.2-1 this works fine but in later contexts the section symbols are so tall that those for 2 and 3 overlap. Here's the pdffont output for the PDF generated by 01.12: name type emb sub uni object ID ------------------------------------ ------------ --- --- --- --------- JWRWBM+LMRoman12-Regular Type 1 yes yes yes 7 0 BRHVGD+CMSY10 Type 1 yes yes no 10 0 And here's the pdffont output for the PDF generated by 01.23: name type emb sub uni object ID ------------------------------------ ------------ --- --- --- --------- EXKOFC+LMRoman12-Regular Type 1 yes yes yes 7 0 JRTCBR+LMMathSymbols10-Italic Type 1 yes yes no 10 0 The section symbols look OK once they reach print preview but the mess in the PDF viewer from section symbols and other characters means that I have to keep using 2007.01.12.2-1 for now. My lmodern is 1.00-3 and my pdftex is pdfetex 1.30.5-2.2 from texlive-base-bin 2005.dfsg.2-10. Is this something you can reproduce or something I've messed up in my configuration? Thanks, --Mike Bird

Hans suggested: >> Giving two passon options also doesn't work, at least not that I >> could find. > you can run with --verbose to see what is passed Good idea. Indeed, only one the first option is passed to pdftex: $ texexec --verbose --nonstopmode --pdf \ --passon="-file-line-error -recorder" a.tex | grep 'running.*pdftex' TeXExec | running: pdftex -progname=context -fmt=cont-en -translate-file=natural.tcx -file-line-error --8bit a.tex \emergencyend -Sanjoy `A nation of slaves is always prepared to applaud the clemency of their master who, in the abuse of absolute power, does not proceed to the last extremes of injustice and oppression.'

regression testing: page image differences
by Sanjoy Mahajan 06 Feb '07

06 Feb '07

Here are output differences between 20070112 and 20070123, mostly to test the regression tests. Here's how to decode it. The line WARN: tex/context/base/math-pln.tex/test-001-20070112-20070123.report means tex/context/base/math-pln.tex/test-001.tex was run through 20070112 and 20070123 to make pdf files, converted to bitmaps, and subtracted (page by page), and that there were some differences. The line [p.0001] 0.176462 dB diff [see png's in /tmp/tmp.mRMxS24124/] menas that p.1 was different in the two runs, but only slightly (about 0.2 dB). Here another example with a slightly larger dB difference: WARN: tex/context/base/core-mat.tex/test-001-20070112-20070123.report [p.0001] 5.00882 dB diff [see png's in /tmp/tmp.UllhY25247/] for which I've attached the two images and their difference. It's slight character position shifts, I think.

regression testing Makefile
by Sanjoy Mahajan 05 Feb '07

05 Feb '07

The contexttest repository now contains a Makefile to use for checking one context tree against another. There's a README alongside it but here's the quickstart svn export . /tmp/testdir cd /tmp/testdir make -k A=20070112 B=20070123 >& world.log (the -k is so it doesn't stop on the first error) It will 1. (if not already done) Download ConTeXt versions 2007.01.12 and 2007.01.23 from the museum, put each in its own subtree, make formats for each 2. Do the following for each test-NNN.tex file: a. Run it through 2007.01.12 to make test-NNN-20070112.pdf b. Run it through 2007.01.23 to make test-NNN-20070123.pdf c. Feed those pdfs to utils/compare-pdfs.sh to generate a bitmap diff d. Report differences found by compare-pdfs.sh (dB on each page) It was interesting running it. I haven't sorted through all the output yet, but a one point was that a few unicode fonts are a problem (maybe because I don't have them, but it makes texexec loop for a long time doing mktextfm and the like). More details to follow. Notes: If you want to view the image diffs as they are generated, set the viewer shell variable in compare-pdfs.sh (I often use xloadimage). I'd be very surprised if the Makefile worked on anything but Linux (uses features of bash + GNU make). I was pretty careful about re-entrancy, so the following works fine at least in my testing: make -k -j 4 A=20070112 B=20070123 -Sanjoy `A nation of slaves is always prepared to applaud the clemency of their master who, in the abuse of absolute power, does not proceed to the last extremes of injustice and oppression.'

--passon won't pass on two arguments to pdftex
by Sanjoy Mahajan 05 Feb '07

05 Feb '07

Also from the testing scripts, another small buglet. I can't figure out how to pass on two cmdline arguments to pdftex. I tried these ways texexec --nonstopmode --passon="-file-line-error -recorder" a.tex texexec --nonstopmode --passon="-recorder -file-line-error" a.tex but it seems that only the first piece is passed on (either -file-line-error or -recorder), rather than both. (Linux, i386, Ubuntu, bash shell, 2007.01.23 version). Giving two passon options also doesn't work, at least not that I could find. -Sanjoy `A nation of slaves is always prepared to applaud the clemency of their master who, in the abuse of absolute power, does not proceed to the last extremes of injustice and oppression.'
