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.'

texexec and return value
by Norbert Preining 05 Feb '07

05 Feb '07

# texexec --nonstopmode --fast --make --pdftex cont-en TeXExec | using search method 'kpsewhich' TeXExec | using existing database TeXExec | using tex engine pdftex TeXExec | using tex format path /var/lib/texmf/web2c/pdftex TeXExec | unable to make format due to lack of permissions TeXExec | TeXExec | TeXExec | TeXExec | runtime: 0.195613 # echo $? 0 # Can we fix this? The lack of permissions is of course a fake, the problem is that there is a link pdftex -> pdfetex in /var/lib/texmf/web2c/, but no directory pdfetex.

feature requests from contextgarden
by Mojca Miklavec 05 Feb '07

05 Feb '07

Hello, it would probably make sense to delete this page: http://wiki.contextgarden.net/Feature_Requests I moved some items here: https://foundry.supelec.fr/tracker/index.php?group_id=21&atid=164 For the remaining ones I have no idea whether they can be considered as feature requests or not. (OOo's XML format might be a good idea, but too much work, \textmu might be resolved with OpenType/Unicode with no extra work, \Fixme only makes sense if someone is willing to try it out & going to use it) But I don't know which other feature requests that I copied make sense either ... I haven't found any option to change priority (perhaps I just don't have enough rights). Mojca

texexec --timeout=NN should return nonzero code on timeout
by Sanjoy Mahajan 05 Feb '07

05 Feb '07

Here is what has come up from the regression testing. [I'll send them one issue/email.] If a texexec job runs out of time (--timeout=NN), the exit code should be nonzero. Right now it's zero; which, I just realized, had slightly confused the error handling by the regression-testing. Here's an example using one of the problematic files in the test repo. [Send the output to a file because it's grows to 14MB.] This command texexec --nonstopmode --timeout=10 tex/context/base/unic-002.tex/test-001.tex exits with error code 0, but this one texexec --nonstopmode tex/context/base/unic-002.tex/test-001.tex exits with error code 1. Maybe if it times out it should exit with its own code (who knows, maybe 23?). [I'm testing the above with 2007.01.23] So I wrote a short Python script (utils/run-it.py in the repo) to handle maximum time and maximum filesize, which the Makefile now uses to wrap the texexec call. -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.'

[contexttest-Feature Requests][72] Extending \placefloat{top,left}. {bottom,outer}, ...

Version: None Category: None Initial Comment: (From contextgarden.net) The \placefigure macro should be extended to combinations like \placefigure{top,left} or \placefigure{bottom,outer} The reason for this request is that we use ConTeXt a lot for typesetting books from "arts and humanities". There we often have to place a lot of (more then 100) figures at "fixed" positions like top-outer and bottom-inner, wrapped by text. I guess it's not a trivial feature to be implemented in TeX's paragraph processing, but I know it might be worth the effort: ConTeXt's way to deal with fonts and text is so superior that it should be also accessible for disciplines that besides text also rely on images - as the arts and humanities do. ---------------------------------------------------------------------- You can respond by visiting: http://foundry.supelec.fr/tracker/?func=detail&atid=164&aid=72&group_id=21
