protrusion with opening exclamation and question marks
by Pablo Rodriguez 30 Aug '18

30 Aug '18

Hi Hans, I have the following sample: \definefontfeature[default][default] [protrusion=quality] \setupxtable[frame=off, option=stretch] \startbuffer[standard] ¿Cómo? ¡No! \stopbuffer \startbuffer[right] \hfill¿Cómo? \hfill¡No! \stopbuffer \starttext \startTEXpage[offset=2em] \startembeddedxtable[framecolor=red, align=hanging, foregroundstyle={\ss\bfd}, offset=overlay] \startxrow \startxcell[leftframe=on] \getbuffer[standard]\stopxcell \stopxrow \startxrow[toffset=2em] \startxcell[rightframe=on] \getbuffer[right]\stopxcell \startxcell[rightframe=on, align=nothanging] \getbuffer[right]\stopxcell \stopxrow \stopembeddedxtable \stopTEXpage \stoptext It shows that question and exclamation marks are sligtly protruded. Well, in Spanish (and Galician in some ortographies) there are opening exclamation and quotation marks. I think it would make sense to have the same protrusion values for opening quotation and exclamation marks as for the closing ones. Many thanks for your help, Pablo -- http://www.ousia.tk

\startuserdata syntax questions
by Rik Kabel 29 Aug '18

29 Aug '18

Wolfgang, Hans, et al, The new \startuserdata macro looks very promising, and can simplify some work I have in progress. The first question: the wiki example and the source use \userparameter{optionkey} \userparameter{anotherkey} to retrieve the value of optionkey and anotherkey. Is there a way to provide the key/value pairs in a manner that they can be retrieved with the getparameters mechanism, as: \getrawparameters [XX] [optionkey=,anotherkey=,#1] This has the added advantage of allowing the setting of a default value, as \getrawparameters [XX] [optionkey=2em,anotherkey=,#1] Or is there a reason not to use getparameters in this setting? The second question: Is there the possibility to enhance the syntax so that one can write \startMyStuff [optionalkey=value, anotherkey=value] stuff \stopMyStuff instead of \startuserdata [MyStuff] [optionalkey=value, anotherkey=value] stuff \stopuserdata Such syntactic sugar makes sweeter reading of the text, and makes clearer what is being done when nesting the macro. -- Rik Kabel

split long formula in two pages
by Jeong Dal 29 Aug '18

29 Aug '18

Dear all, Sometime ago, I asked about the splitting the long formula. Since it is seldom to have a long formula, I manually break the formula using \startformula\startalign … formula \stopalign\stopformula \startformula\startalign … formula \stopalign\stopformula at the final stage of editing. It is more economical than to make some functions for this purpose, I think. Thank you for reading. Best regards, Dalyoung

With \xmltag{#1} one can find the identity of the current node. But how can I find the tag of the parent node? dr. Hans van der Meer

definefallbackfamily stopped working for text fonts
by Henri Menke 28 Aug '18

28 Aug '18

Dear list, In the latest beta the font fallback using a text font in math mode does not work anymore. The log contains messages like char 𝑐 (U+1D450) in font 'MinionPro-It' with id 8: missing char 𝑎 (U+1D44E) in font 'MinionPro-It' with id 8: missing char 𝑏 (U+1D44F) in font 'MinionPro-It' with id 8: missing which is not surprising because a text font does not have math italics. How can I get this to work again? MWE below. Cheers, Henri --- \definefontfamily [mainface] [rm] [Minion Pro] \definefallbackfamily [mainface] [math] [Minion Pro] [math:lowercaseitalic] [force=yes] \definefallbackfamily [mainface] [math] [Minion Pro] [math:digitsnormal] [force=yes] \definefontfamily [mainface] [math] [TeX Gyre Pagella Math] \setupbodyfont[mainface] \starttext \input ward \startformula c^2 = a^2 + b^2 \stopformula \stoptext

luatex
by Hans Hagen 28 Aug '18

28 Aug '18

Hi, We're in the process of pushing a new luatex binary to the garden. It might be that context and luatex are out of sync (version checking stuff) but all will be well in a while.

Re: [NTG-context] closesymbol on same line as displayed formula

Dear Aditya, Thank you for the reply. >> \startproof >> \startitemize[n] >> \item first line. >> \item second line > > Add: \placeclosesymbol here > >> \stopitemize >> \stopproof >> >> \stoptext > It works in many cases that item content ends with words. But it is not working if the item contents end with \stopformula. If I put \placeclosesymbol before \stopformula, then it is shown just after the last word. Anyway, it works in most cases. Thank you again.

question about German hyphenation
by Pablo Rodriguez 28 Aug '18

28 Aug '18

Dear list, I have the following sample: \starttext \de\hyphenatedword{Rindfleisch} \de\hyphenatedword{Rindfleischetikettierung} \stoptext I’m not a native speaker, but I think that "Rindfleisch-etikettierung" is right in German. (And I think that "Rindflei-schetikettierung" is wrong.) Are the hyphenation patterns wrong in the cases above, or am I missing something? Many thanks for your help, Pablo -- http://www.ousia.tk

Re: [NTG-context] closesymbol on same line as displayed formula

Hi, I am sorry to bring up old topic “Re: closesymbol on same line as displayed formula” again. (ntg-context Digest, Vol 153, Issue 40) Is there any progress after that? It seems to me that there is no more discussions about it. The same thing happens after the itemization as in the following MWE. Thank you for reading. Best regards, Dalyoung \defineenumeration[proof][text=Proof.] \setupenumeration[proof] [number=no, closesymbol=\mathematics{\square}, closecommand=\ifmmode\eqno\else\wordright\fi] \starttext \startproof This is a simple proof. \stopproof \startproof This is another simple proof that ends with a formula \startformula 1+1=2. \stopformula \stopproof \startproof \startitemize[n] \item first line. \item second line \stopitemize \stopproof \stoptext

split long formula in two pages
by Jeong Dal 27 Aug '18

27 Aug '18

Dear all, Sometimes, I wrote a long formula using \startformula\startalign … \stopalign\stopformula. In that case, if the remaining space in the current page is not enough to contain the formula, then it adds ‘page break’ and write the whole formula int the new page. I have read a discussion to split long table in two pages. Is there a similar way for long formula? Here is a minimal example. \showframe \starttext \dorecurse{3}{\input knuth} \startformula\startalign \NC S_1 \NC = 1 = 1 + 0 \bigg( \frac{1}{2}\bigg), \NR \NC S_2 \NC = 1 + \frac{1}{2} = 1 + 1\bigg( \frac{1}{2}\bigg), \NR \NC S_4 \NC = 1 + \frac{1}{2} + \bigg( \frac{1}{3} + \frac{1}{4} \bigg) \NR \NC \NC > 1 + \frac{1}{2} + \bigg( \frac{1}{4} + \frac{1}{4} \bigg) = 1+ 2\bigg( \frac{1}{2}\bigg), \NR \NC S_8 \NC = 1 + \frac{1}{2} + \bigg( \frac{1}{3} + \frac{1}{4} \bigg) + \bigg( \frac{1}{5} + \frac{1}{6} + \frac{1}{7} + \frac{1}{8} \bigg) \NR \NC \NC > 1 + \frac{1}{2} + \bigg( \frac{1}{4} + \frac{1}{4} \bigg) + \bigg( \frac{1}{8} + \frac{1}{8} + \frac{1}{8} + \frac{1}{8} \bigg) = 1 + 3\bigg( \frac{1}{2}\bigg) \NR \stopalign\stopformula \stoptext Thank you for reading. Best regards, Dalyoung
