Thanks Wolfgang. I located mtx-epub.lua and now I am getting with mtxrun --script mtx-epub --make --purge test the error mtx-epub | unknown specificaton file 'test-export/test-pub.lua' for ‘test' I tried other things than ’test’ to no avail. I am using the most recent minimal, so I think I have everything Matthias

Hi, I am trying to export to epub. I found epub-mkiv-demo.tex and export-example.tex, and both compile fine, generating the XML tree. The instructions say that I have to run mtxrun --script epub --make --purge test but I get unknown script ‘epub.lua’. I don’t have epub.lua anywhere.

The filename of the scrip is mtx-epub.lua and the path is <TEXROOT>\tex\texmf-context\scripts\context\lua

...

It also says that the console would tell me what script to run, but it only tells me mtx-context | pdfview methods: auto default evince okular pdfxcview sumatra zathura, current method: sumatra (directives_pdfview_method) pdfview | command: wine "sumatrapdf.exe" -reuse-instance -bg-color 0xCCCCCC "epub-mkiv-demo.pdf" 1>/dev/null 2>/dev/null & The directories with the XML trees contain a script epub-mkiv-demo-pub.lua which I can run, but it doesn’t seem to do anything. I am clearly doing something wrong. Any hints on how to proceed will be much appreciated.

It's possible your installation is missing files, the best solution is to use the minimal version from the pragma site: https://www.pragma-ade.nl/install.htm

Thanks, yes, I used to have several, but now I have only one (I deleted the directories for the others). Is there a simple way to fix this? Matthias

Do you have (or had one in the past) another TeX installation on your system, PATH entries for multiple installations can cause problems.

I am on a Mac, and the only directory in the PATH that is TeX related is /Library/TeX/texbin, which is for an old TeXLive that I don’t use anymore. Should I delete that and put something else into it? Matthias

What system do you use?

On Mac and Linux you can use

echo $PATH

on the terminal to get a list with all entries in the PATH variable.

Usually TeXShop. Should I create a new account for a fresh install? Matthias

How do you run ConTeXt, only with a TeX editor like TeXshop or do you use the command line?

You can also try to delete your current ConTeXt installation and reinstall everything from scratch.

Thank you Wolfgang. A fresh install fixed my initial problems. mtxrun --script mtx-epub --make --purge epub-mkiv-demo produces an epub. However, both Calibre and Thorium have trouble with it (not displaying anything but error messages). Are there any steps I need to follow to create a readable epub? Thanks again, Matthias

Delete the directory with your ConTeXt installation and download the zip file from the Pragma site to reinstall ConTeXt.

How do you run mtxrun from TeXShop because you didn't (if I get your previous mail right) add the path for the TeX binaries to your PATH variable?

Wolfgang
