decomposed and precomposde glyphs
by Ulrike Fischer 24 Feb '17

24 Feb '17

When using input like the following with xetex then harfbuzz kicks in and one would always get the good looking precomposed U+1EA0 for the A and the decomposed B+U+0323 for the B. With context (and lualatex) one get a rather bad looking -- as the dot is misplaced -- output for the A^^^^0323 input and no output at all for ^^^^1e04. As the coverage for precomposed glyphs varies a lot across fonts this is rather a nuisance. Is there a way to get the fontloader (also the one used by luaotfload) to do a similar substituation as done by harfbuzz? \starttext \catcode`\^= 7 Ạ A^^^^0323 %decomposed input -> U+1EA0 with xetex Ạ ^^^^1ea0 %precomposed input Ḅ B^^^^0323 %decomposed input ^^^^1e04 %precomposed input -> B+U+0323 with xetex \stoptext (I added the ^^-notation to avoid problems with copy&paste) -- Ulrike Fischer http://www.troubleshooting-tex.de/

controlling title head distances when grid is enabled
by Csikos Bela 23 Feb '17

23 Feb '17

Dear context users: I would like to typeset my documents to gridlines. If grid is enabled, the distances between titles (section, subsection,subsubsection heads) and text are too big. Here's an example: \setuplayout[grid=yes] \showgrid \starttext \section{Section One} \input tufte \subsection{Subsection One} \input ward \subsubsection{Subsubsection One} \input tufte \section{Section Two} \subsection{Subsection Two} \input davis \subsection{Subsection Three} \input dawkins \stoptext In the output there are 3 empty lines before and 2 after Subsection One. It would be enough 2 and 1 lines, respectively. On page 2, between Section Two and Subsection Two heads 4 empty lines are inserted, which is to much (ugly). How can I control the empty space before and after heads when grid is enabled? I tried this: \setuphead[section][before=\vskip-2.8ex,after=\vskip-2.8ex] but it removes all spaces not only 1 line. I also tried \setuphead[section][before={\blank[2*line]},after={\blank[line]}] but it doesn't have any effect. Thank you in advance, bcsikos

Hi, what is the easiest way to export a lua table (mostly key-value pairs) into a XML file? I found 'lxml.save', but no luck with a converter function. Any help welcome. Peter

Purpose/use of loadsetup interface *.xml files
by Stephen Gaito 23 Feb '17

23 Feb '17

Hello, Problem: -------- I am having trouble getting a simple module's documentation to load setup information. Question: --------- Where can I find up-to-date documentation on the load setup interface file use and required format? Background: ---------- I have a current standalone ConTeXt installation with only luatex(mkiv) and all modules (updated yesterday). I intend to write a number of ConTeXt modules to assist in my work. My first module is ConTests a simple wrapper around lua's lunatest framework. ( GitHub: stephengaito/ConTests ) As I work I like to write unit-tests and documentation concurrently with the code itself (as much as possible). I am basing my documentation effort on t-fancybreak.mkvi. As such I have written a setup interface file t-contests.xml. My directory structure is: t-contests/tex/context/interface/third/t-contests.xml t-contests/tex/context/third/ConTests/t-contests.mkiv t-contests/tex/context/third/ConTests/t-contests.lua I am building my module documentation using: mtxrun --script modules --process t-contexts.mkiv (inside the t-contests/tex/context/third/ConTests directory). The resluting t-contests-mkiv.pdf file has 'MISSING SETUP' where I would expect the \showsetup{loadSuite} output to be placed. The mtxrun log output has the line: xml > core > load error in [id: setups:, file: .xml]: empty xml file I interpret this to mean that my interface file was not found (or possibly not correctly specified). The relevant contents of t-contests.mkiv are: ------------ %M \usemodule[contests] %M \loadsetups[t-contests.xml] \writestatus{loading}{ConTeXt User Module / ConTests} %D \subject{Implementation} \unprotect \ctxloadluafile{t-contests} %D \macros{loadSuite} %D %D \showsetup{loadSuite} \def\loadSuite#1{\directlua{thirddata.contests.lunatest.loadSuite('#1.lua')}} \protect \endinput ----------------- The contents of t-contests.xml is: -------------- <?xml version="1.0" encoding="UTF-8"?>   <cd:interface xmlns:cd="http://www.pragma-ade.com/commands" name="context" language="en" version="2010.06.21"> <cd:command name="loadSuite" generated="yes" file="t-contests.mkiv"> <cd:sequence> <cd:string value="loadSuite"?> </cd:sequence> <cd:arguments> <cd:content n="1" optional="no"/> </cd:arguments> </cd:command> </cd:interface> ----------------- Any and all assistance would be greatly appreciated.

Questions on new bibliography system (btx)
by Rik Kabel 22 Feb '17

22 Feb '17

I have a few questions about the new bibliography system. The following example code illustrates the problems. \startbuffer[TestBib] @OTHER{Author1975a, author = {An Author}, title = {A title}, year = {1975}, } @OTHER{Author1975b, author = {Author, An}, title = {Another title}, year = {1975}, } @OTHER{Else1975a, author = {Somebody Else}, title = {A third title}, year = {1975}, } @OTHER{Else1975b, author = {Somebody Else}, title = {A last title}, year = {1975}, } @FILM{Movie, producer = {Normal Name}, director = {Funny Name}, title = {Who Knew?}, year = {2010}, publisher = {Producer}, address = {Hollywood} } @INBOOK{Subtitle, author = {Sally Subtitle-Spacing}, title = {Another Country}, year = {1958}, publisher = {Publisher}, address = {City}, volume = {16}, booktitle = {On the road}, booksubtitle = {Books and essays written while traveling under cover}, } \stopbuffer \loadbtxdefinitionfile[apa] \usebtxdefinitions [apa] \usebtxdataset [TestBib.buffer] \definebtxrendering [Pubs][apa] \starttext \nocite[*] \placelistofpublications[Pubs] \stoptext How can I get “An Author” treated like “Author, An” as in the OTHER examples? The result should like like that of “Somebody Else”. Bibtex databases have both forms and it would be nice if the work was done by ConTeXt automatically. The manual suggests that fields like director (see the FILM example) can be induced to be treated as author/editor names by sufficiently advanced users. Would such a user please share the method? In the INBOOK example, can we get a BOOKSUBTITLE field to complement the BOOKTITLE? My real bibliography has some very long titles, and I would rather have only the main part appear with \cite[booktitle][entry], yet have the title with subtitle in the bibliography. Also in the INBOOK example, I notice that the spacing after “Vol.” is a sentence space, and it should not be. The spacing after abbreviations in the bibliography should not depend on setting frenchspacing. -- Rik

Underful with \startalignment[flushright]
by josephcanedo＠gmail.com 21 Feb '17

21 Feb '17

Dear list, Could not find any hint on this list on this (minor) problem. When compiling the following simple MWE : \starttext \startalignment[flushright] Foo. \stopalignment \stoptext I get an underful hbox message : Underfull \hbox (badness 10000) in paragraph at lines 4--5 []\3>modern-designsize-12pt-rm-tf-0--0 Foo. Is there a simple way to avoid the underful message (other than adding a \hfil before the text) ? \starttext \startalignment[flushright] \hfil Foo. \stopalignment \stoptext Many thanks Best regards Joseph Canedo

description questions
by Csikos Bela 21 Feb '17

21 Feb '17

Dear context users: I am experimenting with descriptions and I couldn't find in the documentation the following: 1. What is the default value of width option? It seems that default width uses the longest head + some distance for every head in a descriptions list. Neither width=fit nor width=broad,distance=dimension results in the same. 2. In the same document how can I reset to the default options of a defined description list? For example: \definedescription[defa] \defa{head} .... % deafult options are used \setupdescription[defa][width=broad,distance=1cm] \defa{head} .... % above options are used Now I would like to use again the default options, how can I? I tried: \setupdescription[defa][] \defa{head} .... But still the previously set options are used, they haven't been reset. Thank you in advance, bcsikos

Suddenly, my font is not used any longer
by Nicola 21 Feb '17

21 Feb '17

Hello everyone, I am re-typesetting a mkiv document that uses system fonts for text and math (through \definefontfamily). Suddenly, it renders Latin Roman for the text. May it be a cache corruption problem? I recall that there's a command to clear the font cache, but I cannot remember which. Nicola

أربعين حديثاً من أحاديث رسول الله ، ذكر النووي في مقدمة الأربعين له وروده عن تسعة من أصحاب رسول الله سمَّاهم، وقال: (( واتَّفق الحفاظ على أنَّه حديث ضعيف وإن كثُرت طرقُه ))، وذكر أنَّ اعتمادَه في تأليف الأربعين ليس عليه، بل على أحاديث أخرى، مثل قوله : (( ليبلِّغ الشاهد منكم الغائب ))، وقوله: (( نضَّر الله امرءاً سمع مقالتي فوعاها )) الحديث، وذكر ثلاثة عشر من العلماء ألَّفوا في الأربعين، أولهم عبد الله بن المبارك، وآخرهم أبو بكر البيهقي، وقال بعد ذكرهم: (( وخلائق لا يُحصون من المتقدِّمين والمتأخرين ))، وقال: (( ثم مِن العلماء مَن جمع الأربعين في أصول الدِّين، وبعضهم في الفروع، وبعضهم في الجهاد، وبعضهم في الزهد، وبعضهم في الآداب، وبعضهم في الخطب، وكلُّها مقاصد صالحة رضي الله تعالى عن قاصديها، وقد رأيتُ جمع أربعين أهم من هذا كلِّه، وهي أربعون حديثاً مشتملة على جميع ذلك، وكلُّ حديث منها قاعدة عظيمة من قواعد الدِّين، قد وصفه العلماء بأنَّ مدارَ الإسلام عليه، أو هو نصف الإسلام أو ثلثه أو نحو ذلك، ثم التزمتُ في هذه الأربعين أن تكون صحيحة، ومعظمها في صحيحي البخاري ومسلم، وأذكرها محذوفة

الحنبلي رحمه الله، وقد رأيتُ شرح هذه الأربعين مع زيادة ابن رجب شرحاً متوسِّطاً قريباً من الاختصار، يشتمل شرح كلِّ حديث على فقرات، وفي ختامه ذكر شيء مِمَّا يُستفاد من الحديث، وقد استفدت في هذا الشرح من
