How to scale an external figure from lua ?
by josephcanedo＠gmail.com 09 Nov '15

09 Nov '15

Dear all, I am trying to write some lua code that loads some pdf file and scales it. I have the following code (got from previous question here to get number of pages from a pdf and from source files). local figure = figures.push { name = filename, scale = N } -- scale value does not seem to be taken in account assert(figure, 'Could not load figure from file ' .. filename) figures.identify() figures.check() figures.dummy() -- needed ? figures.scale() -- how to pass the scaling factor ? local d = figures.done() print('Scales ' .. figure.status.xscale .. ' ' .. figure.status.yscale) -- outputs Scales 1 1 figures.pop() Hoping that’s possible to do in lua code and my questions are not too dumb (still a beginner in ConTeXt). Many thanks for your help, Best regards JC

Kerning and ligatures in math roman font
by Ulrike Fischer 09 Nov '15

09 Nov '15

In this example there is no kerning and no ligatures in the math: \starttext WAiff $\mfunction{WAiff}$ \stoptext This is a different behaviour than with legacy math fonts. A question about this has been asked some month ago on tex.sx (http://tex.stackexchange.com/questions/252493/ligatures-are-not-used-in-ope…) The problem (or feature) exist also with xetex. With luatex one can avoid to loose the kerning by loading as math roman font a font in mode base (http://tex.stackexchange.com/questions/277362/lualatex-no-kerning-within-op…, I have no idea how to do this in context). Is this a luatex/xetex bug? Or a feature? How could one enable kerning and/or ligatures without going back to base mode? -- Ulrike Fischer http://www.troubleshooting-tex.de/

Ligatures and copy-paste
by Tommaso Petrucciani 09 Nov '15

09 Nov '15

Dear list members, is there some command to issue in order to have ligatures copy-paste correctly in PDFs? I thought Mk IV did this automatically, but it’s not working on my system. Ligatures paste as spaces and searching the PDF doesn’t find the words. I use ConTeXt beta 2015-10-09, Apple Preview and Skim as readers. My code now is just: \starttext effective and efficient \stoptext Thanks in advance, Tommaso Petrucciani

Hyphenation, OTF font and tagging
by Christoph Reller 09 Nov '15

09 Nov '15

Hi, I have a strange behavior with the latest beta: - OpenType Font "Myriad" - Tagging enabled Result: Hyphenation is not working, i.e., the hyphens disappear. Example output correct (when disabling tagging): [...] If I had not partici- pated fully [...] Example output defect (when enabling tagging): [...] If I had not partici pated fully [...] MWE: \setuptagging[state=start] %<- correct when commenting this line \starttypescript[sans][myfont] \definefontsynonym[Sans][file:MyriadPro-Regular] \stoptypescript \definetypeface[Body][ss][sans][myfont] \setupbodyfont[Body,ss,10pt] \starttext \input knuth \input tufte \input reich \input linden \input darwin \stoptext Any feedback is welcome. @Hans: I can provide the Myriad font if this helps. Cheers, Christoph

footnotes in frames
by Thomas A. Schmitz 09 Nov '15

09 Nov '15

Hi, is it, by any kind of magic, possible to have footnotes within a frame (no float) that will be typeset with the normal footnotes flow? Something like \starttext one\footnote{1} two\footnote{2} \framed{three\footnote{3}} four\footnote{4} \stoptext I have found some threads about similar questions, but no real solution. Thanks!

Another issue with EBGaramond / firstline / mixedcolumns
by josephcanedo＠gmail.com 08 Nov '15

08 Nov '15

Dear all, Trying to use EB Garamond font Inside mixed columns + use firstline feature (to make it larger) I get an empty line in output between first line and the rest of paragraph. If I comment the line containing \setupbodyfont and use default font the problem disappears (even with larger \tfa ratios well above 2). The problem seems only to happen when first line contains letters with space hanging below line base (like g or p for example). As well using columnset does not show the problem and using grid=verytolerant as well. Attached MWE + output. Many thanks Best regards Joseph Canedo

How to place background text on proper page
by Sytse Knypstra 06 Nov '15

06 Nov '15

Dear list members, In the following minimal example the last block (on the background) is placed on page 3 while there is ample room for it on page 2. Only when the \page command in line 6 is uncommented, this block is placed on page 2. Is there a better way to force placement on page 2 or should I always put a \page command at the bottom of the previous page? My '\page solution' has the disadvantage that, when applied in the middle of a sentence, the last line on the page is usually not aligned. \define\block{\input knuth \blank} \starttext  \block \block \block % still on page 1 %\page  \block % partially on page 2 \startbackground  \block % only on page 2 if \page is uncommented \stopbackground  \stoptext Thanks in advance, Sytse Knypstra

Awesome Fonts in item lists
by Romain Diss 04 Nov '15

04 Nov '15

Hi all, I'm not a font expert with ConteXt so maybe my question is trivial but is there a simple way to use Font Awesome Icons in ConTeXt, for example as symbols in an item list. Thanks in advance. All the best. -- Romain Diss

Problem using markings
by josephcanedo＠gmail.com 04 Nov '15

04 Nov '15

Dear all, I would like to display in page header the number of first and last subsection that starts on a given page (ie the title of those appear on that page regardless their content). For this I tried using \fetchmarking[subsectionnumber][][top] and \fetchmarking[subsectionnumber][][bottom] but it does not give me the expected results if (it seems) the page does not start immediately with a new subsection (ie there is text of subsection starting from previous page). In the example below in page 2 I’d like to have 1.4 - 1.6, but top marking equals to 1.3 in this case. In the other pages top marking contains expected number (well the number I’d like to print). I guess there is some logic to use using previous, top and first markings but I fail to understand what it could be. Many thanks Best regards Joseph Canedo

math fractions
by Alan BRASLAU 04 Nov '15

04 Nov '15

Hi, Does anyone have a suggestion to generate a better result for the symmetry specification: \starttext ${2\over a}{2\over b}{2\over m}$ \stoptext I tried: \starttext ${2\over \vphantom{b}a}{2\over \vphantom{b}b}{2\over \vphantom{b}m}$ \stoptext but this leaves too much vertical space - compare it to: \starttext ${2\over \vphantom{b}a}{2\over b}{2\over \vphantom{b}m}$ \stoptext Can this be a bug in ConTeXt math spacing? Alan
