Page count of PDF file from lua
I can't figure out how to determine the number of pages of a PDF file within lua. From the TeX side it works with \getfiguredimensions Can somebody give me a nudge in the right direction? Example: \starttext % Works %\getfiguredimensions [somefile.pdf] \startluacode -- Does not work context.getfiguredimensions({"somefile.pdf"}) local numpages = figures.get("used", "pages", 0) context(numpages) \stopluacode \stoptext Marco

Thanks for the snippet, Hans. Marco

Thanks, Lukáš. That also works. Unfortunately, I didn't find the thread while searching the list. I did a quick benchmark which revealed that both solutions perform almost the same. I guess they use the same backend code. Marco
Having an issue in my pdf-output after processing a markdown file to .tex --> .pdf It adds the word "stylecolors" in the .pdf file Why is it doing that?

Possibly because there was a bug in the version of the filter module (2011.12.17) that you are using. It works fine with version (2012.01.26) or (2012.02.11). The easiest fix is to update your context distribution and get the latest version of the module. If you don't want to update the entire distribution, just get the latest version of t-filter.mkiv, t-module-catcodes.tex from https://github.com/adityam/filter; Although I haven't tested if the latest version of the filter module works with old ConTeXt format. You are using 2011.05.18 and lots of ConTeXt internals have changed since then. The other option will be to pick an old version of the module: https://github.com/adityam/filter/tags Aditya

Actually, the reason is that now the filter module uses \use<namespace>styleandcolor to set style and color: \getvalue{use#1styleandcolor}{#2}{#3} Since \use<...>styleandcolor was introduced after 2011.05.18, the \getvalue evaluates to \relax, and you see "stylecolor" (the value of #2 and #3) in the output.

Updating to latest beta with ./first-setup.sh did the trick, thanks a lot mvh Janneman 22 feb 2012 kl. 18:15 skrev Aditya Mahajan:
