Re: [NTG-context] [XeTeX] longer ConTeXt+XeTeX compile time than before

However, there is no change when I compiled the files using ConTeXt. I tested the same file using the previous ConTeXt version in the another Mac and found that there was no delay. The big difference between them as follows: 1. part of log file under new version . (/usr/local/gwTeX/texmf.pkgs/tex/context/base/cont-err.tex systems : no file 'cont-sys.tex', using 'cont-sys.rme' instead ) ) at here, it paused for long time stdin - speedtest.pdf [1] 8949 bytes written Output written on speedtest.pdf (1 page).

My powerbook is 1.33GHz PowerPC G4. If you have someone to blame, please blame me. I asked Hans if he could add an additional switch -output-driver=xdvipdfmx when running XeTeX. This means that the files are now converted to pdf with xdvipdfmx instead of xdv2pdf. Without that switch one cannot use otf fonts that reside in the texmf tree. That change has happened in the middle of January, so any older ConTeXt probably still runs with xdv2pdf. People on the XeTeX mailing list often ask how to run xelatex with -output-driver=xdvipdfmx switch from emacs etc. I hope that ConTeXt will soon use OpenType LM as the default font, so particularly for that reason, I doubt that switching back to xdv2pdf makes sense. How long is the time delay if you compare the two? If you want to change it on your own computer, find this line in tex.rb and remove the option which sets a different output driver: @@runoptions['xetex'] = [...,'-output-driver=xdvipdfmx ...'] Mojca ___ ntg-context mailing list ntg-context@ntg.nl http://www.ntg.nl/mailman/listinfo/ntg-context

But xdvipdfmx is also faster than xdv2pdf, in most cases. It may be that older ConTeXt scripts didn't run an xdv-to-pdf converter at all until the last of several passes; if you call xetex with the -no-pdf switch on all the preliminary runs, it will skip the conversion and therefore be faster. But I'm not sure exactly how Hans has been doing all this; ConTeXt is a mysterious black box, as far as I'm concerned!

How long is the time delay if you compare the two? Something else to consider: if you repeat the test, are the results still the same? There can be a considerable extra delay on the first run after you change anything about your font configuration, because Apple Type Services has to rebuild a lot of cached information. But if you re-run the job, it may be a lot faster. JK ___ ntg-context mailing list ntg-context@ntg.nl http://www.ntg.nl/mailman/listinfo/ntg-context
