Hi. (I'm reading this ML but rarely ask questions.) I try to understand the purpose of 'setupbackend'. Consider the following three examples: ---------------------------------------------------------------------- <example name="ex1.tex"> \setupbackend[export=yes] \starttext This is simple example. No font switching, no math. \stoptext </example> ---------------------------------------------------------------------- <example name="ex2.tex"> \setupbackend[export=yes] \starttext This is second example. This time we try to use font switching mechanism: This is normal, but this \bold{one is bold}. Normal again. \stoptext </example> ---------------------------------------------------------------------- <example name="ex3.tex"> \setupbackend[export=yes] \starttext This is third example with 'backend' 'export=yes'. Now we try simple math: This is inline formula $E=mc^{2}$. This is display formula \startformula E=mc^{2} \stopformula \stoptext </example> ---------------------------------------------------------------------- I compiled them with context (mkIV, context minimal) and got ex{1,2,3}.export. I thought that I get not only the document content but also its logical structure (for example some markup for font switching). Is it true that 'backend' only output document content not its logic strcuture? Does it work with math? The third example gives for math only not letters. I attached the resulted export files. P.S. Then I saw the announce about 'backend' & 'export=yes' I thought that context would be good tool for notes. I imagine that I could wrote a text file and make from it either pdf (for printing/screening) or html (for screening) or may be convert xml (using existing tools and methods) to other formats (rtf/odt/xhtml) that would contain math, images, tables. But seems that I was wrong or this will be in future of the backend? --- WBR, Vladimir Lomov -- If you make people think they're thinking, they'll love you; but if you really make them think they'll hate you.
