But can I influence it e.g. using 'processors' applied to problematic index entries? Processors can be used for setting the font-weight or color of particular entry. Can the same method used for manual setting of 'keep-with-previous/next' ? Thanks, Jan

According to the proposed solution at http://tracker.luatex.org/view.php?id=865 it can be switched on using this magic formula \enabledirectives[references.bookmarks.preroll] What is the correct usage of this? And are there any details why it is required and what exactly it does? When it is added to the beginning of my example, it returns an error: attempt to call field 'boxtostring' (a nil value) But to be honest, I'd expect setting this flag internally by default as I cannot imagine any use case where the index ID should be preferred in favor of the title...

Automatic adjusting the font size to fill the text-area
by "H. Özoguz" 26 Nov '13

26 Nov '13

Hello there, in my actual book there is one special condition: It is already clear which paragraphs of the text have to be set on page 1, which on page 2 etc.pp. (a nearly 700 pages-project). So there are no page-breaks within a paragraph, no overruns are allowed. But now the question: The text for each page has not always the same length. So on some pages there might be many empty space at the buttom, while on others the textarea is completely filled. At the beginning I have to set an font-size - so I have to set it, such that the longest text fits into the text area on its page. But of course, many other pages maye filled only 60%. (That is the spectrum of the text-lengths in this project). So one direct solution is clear (if one wants to have filled or nearly-filled pages, and I want this): I can change the font-size for every single page. But which size? It is a experiment, so I have to try 10pt, then compile, then 10.8pt .... ok, was too much, got an page-overrun .... lets try 10.4pt ..... and this for every single of the 700 pages. That is possible of course, and if there is no other way, this will be my approach. So: Is there some trick or way for automatically find the best (biggest) font-size (up to some precision, maybe one digit after decimal point in pt), s.t. the text produces no overrun (no page-brake)? I guess no, because ConTeXt had to run the compiling several times or so ... but better to ask and then to begin with the exhausting work. Thanks. Huseyin

Calculating with variables
by "H. Özoguz" 26 Nov '13

26 Nov '13

Hello there, I am new in variables in ConTeXt, so I tried the the following example of two font-sizes wich should have a ratio of 0.7: \setvariables[fontsize][bigsize=17pt] \setvariables[fontsize][smallsize=0.7\getvariable{fontsize}{size}] \definefont[big][name:arial at \getvariable{fontsize}{bigsize}] \definefont[small][name:arial at \getvariable{fontsize}{smallsize}] \starttext \big Dies ist ein großer Text.\blank \small Dies ist ein kleiner Text. \stoptext That does not work, what is the correct syntax? [Second question about this will be much more involving I think ... :), but I will give it his own thread]. Thanks. Huseyin

See attachment, the font is wider, but not bold. See the difference to the intended result, achieved with Corel Draw (with the same font), see attachment. In ConTeXt I had the following code (see attachment for the compiled pdf): ++++++++++++++++ \definefont[arabic][file:bliblablup_0.ttf*arabic at 15pt] \definefont[arabics][file:bliblablup_0.ttf*arabic at 15pt] \definefontfeature[fakebold][extend=1.2] \definefont[arabic][file:bliblablup_0.ttf*arabic,fakebold at 15pt] \starttext \arabic\setupalign[r2l] ??????? ??? ???????? ?????? ???? ???????? ??????????? \blank\arabics\setupalign[r2l] ??????? ??? ???????? ?????? ???? ???????? ??????????? \stoptext ++++++++++++++++ Huseyin

pstrics module again
by DesdeChaves 26 Nov '13

26 Nov '13

Dear sirs The pstrics module don't work anymore. I tried to run this simple code but I found a lot of errors. \usemodule[pstric] \starttext \startPSTRICKS \pspicture(0,0)(20,20) \psline(0,0)(20,20) \psline(1,1)(10,10) \endpspicture \stopPSTRICKS \stoptext This module is no longer supported? There is still any hope of being able to use pstric and some of its extensions (pst-spectra, for example)? Thanks a lot Sorry for my persistence about pstrics module. Thanks a lot Jorge
