PageSetup
by Aidan Nichol 14 Apr '16

14 Apr '16

I’ve been have been having a couple of problems with swapping pages and so I went back to the example in Context Garden using the latest beta \definepapersize[main] [A4] \definepapersize[extra][A4,landscape] \setuppapersize[main] \starttext Page 1. Portrait \page Page 2. Portrait \page \adaptpapersize[extra] Page 3. Landscape \page Page 4. Portrait \page \stoptext The main problem I have is that \adaptpapersize is working as though I had entered \setuppapersize. Page 3 was created as landscape and but it didn’t revert to main to give page 4 as portrait. The secondary issue is that the landscape page is not as expected in that it is a square page. Inserting a \showsetups and \showframe into page 3 I can see that it is layed out Ok but on a large piece of paper. \printpaperwidth and \printpaperheight are both set to 29.7cm. Aidan

Assigning a variable to the list argument in \setupsection
by Michael Guravage 14 Apr '16

14 Apr '16

Greetings, I would like to use a variable for the value of the list argument in, e.g., the \startsection command. If you compile my little example you will see that the first 'literal' assignment works, while the second 'variable' assignment does not. What am I missing here? Cheers, Michael \starttext \placecontent \setvariables[TOC][list=Second Section] \startsection [title={First}, list={First Section}] This is the first section. \stopsection \startsection [title={Second}, list={\getvariable{TOC}{list}}] This is the \getvariable{TOC}{list} \stopsection \stoptext

RTL section heads
by Mohammad Hossein Bateni 14 Apr '16

14 Apr '16

Hi, This is concerning an RTL text. I have one chapter and 10 sections under that. My goal is to achieve the following. 1) The number 10 should appear correctly with '1' visually to the left of '0'. 2) The chapter number should visually appear to the right of the section number. 3) Chapter and section numbers should be separated with a dash. (This is ignored in this email and I will follow up about it in another thread. To get a minimal working example, I also do not try to change the numbers to use Persian digits.) In particular, the headings will be visually something like the following (aligned to the right). elpmas 1 txet 1-1 txet 2-1 txet 3-1 ... txet 10-1 Here's the first attempt. %% Attempt 1 \setupalign[r2l] \starttext \placecontent \chapter{sample} \dorecurse{10}{\section{text}} \stoptext The result is: elpmas 1 txet 1-1 ... txet 01-1 Then I add "\setupdirections[bidi=global,method=default]" to the beginning and I get the most strange result (number right-aligned but texts left-aligned): sample 1 text 1.1 ... text 1.10 A third attempt gives almost what I want (without period as the separator). %% Attempt 3 \setupalign[r2l] \def\LTR#1{{\lefttoright#1}} \def\leftnumbers#1{\LTR{\numbers{#1}}} \defineconversion[leftnumbers][\leftnumbers] \setuphead[chapter,title,section,subject] [conversion=leftnumbers] \starttext \placecontent \chapter{sample} \dorecurse{10}{\section{text}} \stoptext The big problem is that in my RTL documents, I always have the setupdirections command, which messes things up here. (This makes it difficult to one section name with English title, which should still be typeset on the right-hand side of the page.) Note that in attempt 2 above, there were two issues: (1) Text and numbers appeared on the two far ends of the screen instead of being close to each other. This does not happen when I use Farsi text. (2) Chapter number appears to the left of section number. %% Attempt 5 \usemodule[simplefonts] \setmainfont[ALM Fixed][features=arabic,range=arabic] \setupdirections[bidi=global,method=default] \setupalign[r2l] \starttext \placecontent \chapter{نمونه} \dorecurse{10}{\section{متن}} \stoptext Interestingly the table of contents looks fine if I put the number inside an LTR macro; still in the main body, the section heads are typeset incorrectly. %% Attempt 6 \usemodule[simplefonts] \setmainfont[ALM Fixed][features=arabic,range=arabic] \setupdirections[bidi=global,method=default] \setupalign[r2l] \def\LTR#1{{\lefttoright#1}} \def\leftnumbers#1{\LTR{\numbers{#1}}} \defineconversion[leftnumbers][\leftnumbers] \setuphead[chapter,title,section,subject] [conversion=leftnumbers] \starttext \placecontent \chapter{نمونه} \dorecurse{10}{\section{متن}} \stoptext I guess the solution is to get the entire section head number string (e.g., 1.10) to have RTL direction, however, each individual number string inside (say, 1 or 10) should be written LTR. How can this be achieved? The six TeX files (with corresponding PDF outputs) are attached. BTW this is using ConTeXt ver: 2016.04.01 13:01 MKIV beta fmt: 2016.4.7 int: english/english, running LuaTeX, Version beta-0.90.0 (TeX Live 2016) on Mac OS X. Thanks a lot, —MHB

Questions about Scite lexers
by Nicola 13 Apr '16

13 Apr '16

I'm trying to define a custom scite lexer for a toy language I'm using. So far, I've copied a lexer from the distribution, changed its name and keywords, and it's all fine. I have a few questions, though: 1) my custom scite-context-lexer-xxxx.lua is found only if I put it in the distribution. It there a way to have it in my project's folder instead? 2) How do I customize colors? 3) Is it possible to embed TeX commands in \startscite..\stopscite environments, like /BTEX../ETEX in built-in typing? 4) Are scite lexers documented somewhere besides the source code? 5) May I rely on this feature to be stable? 6) It is my understanding that pret-xxx.lua files are obsolete. Is it correct? (If so, it would be nice to update the wiki to reflect that). To be clear, I'm not interested in using the Scite application. I just need to typeset formatted verbatim code. The vim module is fantastic and I already use it, but there are cases where I need a syntax not supported by Vim (and I'd rather avoid defining it on the Vim side) and/or need to embed TeX commands (anywhere, not only in comments).

Move textrule closer to head
by Tom Harrop 13 Apr '16

13 Apr '16

Hello, I'm a ConTeXt beginner. I'm working on a document where I would like a textrule under my subsubsection headings. If I use after=\textrule, the placement of the textrule is too far from the heading, and I haven't found a way to move it closer to the heading either with \setuphead or \setuptextrules. Here is an example: > \setuphead[subsubsection] > [after=\textrule] > > \starttext > > \subsubsection{I would like less space between this heading and its > textrule} > > Here is some text. > > \stoptext > I realise that the spacing looks pretty good in the PDF produced by this example, so you'll just have to believe me that it needs to be closer to the headings in my document. I'd appreciate any help on this, including suggestions of alternative/better methods to do this. Thanks for reading, Tom

Help with t-vim module and math
by Nicola 13 Apr '16

13 Apr '16

Hi, I am using the Vim module to typeset code, and I've found a situation where I'd like to use some math symbols, but not in comments. I am not sure whether it can be done. This is what I have tried: \usemodule[vim] \definefontfamily [slidesfont][mono][Latin Modern Mono Light] \definefallbackfamily[slidesfont][mono][Xits][range={"0222A}] \definevimtyping[pascal][syntax=pascal] \starttext \startpascal X := Y ∪ Z; \stoppascal \stoptext The ∪ symbol does not appear in the output. Am I completely off-track? Nicola

automatically "smashing" È in xml typesetting
by massifr＠fastwebnet.it 12 Apr '16

12 Apr '16

Hello list, I'm typesetting italian text that contains "E" letters with a grave accent, like this: "È". In my "body font environment" the interline space is narrow and those "È" make their lines taller, making every following line move downwards. The problem is easily solvable putting "\smash" before "È". But my sources are XML and typesetting is done through xmlsetups, so I'm looking for an automatic way to replace every "È" in the text with "\smash{È}". Is it possible? Thanks, Massi

Dear All, thanks to the following command I can already filter out everything except under/overfull cases: context --noconsole source.tex It is nice, but would it be possible to print also affected page numbers of the final PDF file? But to be honest, the best for me would be PDF annotations (rectangles) placed to that occurrences. In Acrobat Reader you can easily list them and automatically navigate to the target location (and then jump to the prev/next). Thanks in advance for a new option :-) Jan

Dear Hans van der Meer, Thank you for your sample code. I learned how to pass the value of the variables. BTW, if I change “orange” to “red” or “green”, it is working fine.

\startuseMPgraphic
by Meer, Hans van der 11 Apr '16

11 Apr '16

I seem to remember the following variations in \startuseMPgraphic. (1) \startuseMPgraphic{name}{comma separated list of variables} (2) \startuseMPgraphic{name}{comma separated list of key=value pairs} In the second case one is able to set a default value to that variable, possibly to be overridden with \useMPgraphic{name}{key=value}. I very much would like to specify default values on the \startuseMPgraphic definition of the graphic. However, I cannot get option (2) working. Do I have a bad memory (possible of course ;-), Has it to be done otherwise? In the example below the graphic myname1 is ok, but myname2 gives the following error: metapost > error: >> orange ! Improper type. <to be read again> ; <*> ...raw unitsquare scaled 1cm withcolor orange; minimal example: \starttext \startuseMPgraphic{myname1}{color} pickup pencircle scaled 1mm; draw unitsquare scaled 1cm withcolor \MPvar{color}; \stopuseMPgraphic \startuseMPgraphic{myname2}{color=red} pickup pencircle scaled 1mm; draw unitsquare scaled 1cm withcolor \MPvar{color}; \stopuseMPgraphic \useMPgraphic{myname1}{color=blue} \useMPgraphic{myname2}{color=orange} \stoptext Hans van der Meer

If that hbox is used, the first paragraph is not evaluated correctly and considered as the second one.

TeX "matrix" command not working lately
by L.S.-Soc&Gam 10 Apr '16

10 Apr '16

Hi guys, i've already searched the mailing list for this but i still am having a problem while trying to create a matrix. my code looks like this: \startformula S=\left(*\matrix**{* \sigma_x *&* \tau_{xy} *&* \tau_{xz} *\cr* \tau_{yx} *&* \sigma_y *&* \tau_{yz} *\cr* \tau_{zx} *&* \tau_{zy} *&* \sigma_z *\cr* *}*\right)_{xyz} \stopformula But since a few days, there are only empty braces after compilation. The funny thing is, i worked already. but i've updated context at least once since (only 5 days ago, betas included) and since then after compiling there are only empty braces. When i enter \startformula S=\left( 1234 \right)_{xyz} \stopformula the 1234 shows fine between the braces. so it seems to have to do with \matrix command in some way... i don't know any alternative way to create a matrix. any help would be appreciated. Greetings, Sebastian

defining a comamnd as variable which behaves as constant

Dear list, I have the following document: \mainlanguage[es] \starttext \startTEXpage[offset=1em] \dorecurse{27}% {\def\abcd{\convertnumber{a}{\recurselevel}}% \dorecurse{27}% {\abcd\convertnumber{a}{\recurselevel} }\par} \stopTEXpage \stoptext I want to test all lowercase-letter pairs in Spanish. Excuse me for my missing programming notions. For the sample above, I would need a command that behaves as a variable when defined, but as a constant when invoked. Is there any way to achieve that without using counters? Sorry if there is too much nonsense in the previous paragraph. But I need to know how to do it for another example too.

Weird background colors in autogenerated index
by Jan Tosovsky 09 Apr '16

09 Apr '16

Dear All, since LuaTeXt 0.81 my back-of-the-book index (register) is generated with strange background colors. The index title is typeset in yellowish background and the left column of the last index page has a blue background, see the attachment. I've thought I reported it, but it is still there even in 0.95. It was fine in the version 0.80. Could this be somehow eliminated? Thanks, Jan

Dear All, for an illustration I wanted to colorize all ligatures, but the following method is not reliable for three character ligatures - which ends up black.

Downloading ConTeXt standalone alternatively
by Jan Tosovsky 07 Apr '16

07 Apr '16

Dear All, I've tried to install ConTeXt at work, but it failed because of blocked 873 port used by rsync. Our admins aren't going to open that port in foreseeable future. I don't have any computer outside the firewall to tunnel the port using 'nc' program as described at http://wiki.contextgarden.net/ConTeXt_Standalone - and I am on Windows so I don't have 'ssh' either. Looking into the first-setup.bat and especially to mtx-update.lua all files seem to be picked up on demand and there isn't any repository for ConTeXt Standalone I could download directly (that syncing is not crucial now). Is there more efficient way than packing my home context folder and copying & unpacking it in my work? Thanks, Jan

MPinstance
by dr. Hans van der Meer 07 Apr '16

07 Apr '16

I do not understand the info in the ConTeXt wiki on setupMPinstance. The syntax is specified as \setupMPinstance[...][...,...=...,...0 [...] name format metafun mpost etc. I read this as: in the first argument one can specify a name presumably a name specified on \defineMPinstance. in the second argument [format=metafun] specifies the format. But then the example under Usage gives: \setupMPinstance[metafun][...] Why metafun in the first instead of the second argument as implied in the syntax description? I get confused here. Also in the description \startMPextensions and \startMPinitializations are mentioned, but their descriptions are missing from the list given in the page MetaPost in ConTeXt. How are these described and what is the specific purpose of \startMPextensions compared to \startMPinitializations? What is the recommended use for them? Hans van der Meer

On LuaTeX beta-0.95.0
by luigi scarso 07 Apr '16

07 Apr '16

Hi all, we have put beta-0.95.0 on the luatex svn already from while, but the tag is not frozen because: 1) Hans is working on the manual, 2) I keep source/ in sync with TeXLive (kpathsea files etc ), 3) we fix bugs, of course --- the building process not always goes well on every the platforms that we support. The initial plan was to put 0.90.0 for TeXLive, but now we are pretty confident that 0.95.0 is ok, and we have no plan to touch the codebase in source/ (bug fixing apart). (@Karl: I can keep Master/texmf-dist/doc/luatex/base in sync, if it's ok for you) For those that build from source: A. Kakuto keeps the TeXLive repo aligned with the luatex repo, assuring that the windows binaries are ok. It's clear that, having two repos with the same program, is a bit hard to decide which program is the latest one, so when I import from TeXLive in the commit message I specify the revision (e.g. "sync with TL rev. 40299." ); in the luatex repo, trunk and tags/beta-0.95.0 are always aligned, always first trunk and immediately after beta-0.95.0. I found more simple to have both the repos (texlive and luatex) on my machine, but it's my choice. Unfortunately currently the contextgarden server has some problems, and perhaps not all context users have the latest luatex --- not a big problen, we are working on this. The formal announcement of Luatex 0.95.0 very likely will be when the TeXLive is frozen. around 4may. -- luigi

Consistent random number generation
by Aditya Mahajan 06 Apr '16

06 Apr '16

Hi, Is it possible to generate consistent random numbers across multiple operating systems. For example, consider the following file: math.randomseed(1000) print(math.random()) print(math.random()) print(math.random()) If I process this using texlua, the output on linux and MacOS is different. Is it possible to get consistent output? Rationate: I use randomization to randomize certain paths in metapost. Not all randomly generated paths look okay, so I play around with the seed until I get a good path. But I have to repeat this process everytime I update my distribution and if I compile on different machines. Thanks, Aditya

I didn’t look into that docs, but I’d assume, tracking refers to some logging or visualization of spacing. AFAIR ConTeXt can do that very nicely (while I never used it and don’t know how to enable it).

ConTeXt anew-but where?

05 Apr '16

Dear NTG-ConTeXt list members,[a] Excuse me that I will have to send this email in html format. The very format of this email is not meant to offend anyone consciously (even if perceived so). Paragraph beginnings [a] through [e] may lead you the way, instead.[b] A NEW(er) PROBLEM: After I have decided to re-instal ConTeXt because my previous installation (dating from last quarter of 2014) was from some time on un-updatable (maybe some remember a question posted to this list by me in one of the months passed), a folder named "context" in which one can lay down/ find a skript file (.sh) that is the pivot of "any" update to come IS APPARENTLY ABSENT.[c] WHY COULD THAT BE OF INTEREST? ...simply because I wondered throughout this second installation process whether there would be any question which path that very folder should finally have DID SIMPLY NOT SURFACE (the old "context" folder formerly in "/home/myUsername" was discarded).[d] QUESTION: Where, consequently, on a Kubuntu Linux operating system (version LTS 14.04 on a 64bit architecture) was one to look for that folder to be able to eventually perform an update via command line (= bash console) as "http://wiki.contextgarden.net/ConTeXt_Standalone" [Ref-1] describes what the user should do in advance to any update attempt, and thus, following installation? I feel awkward when it comes to that issue as I already asked for an update option earlier.[e] Thank you very much for your precious time.Best regards,Markus Hofstetter

Dear ConTeXters & LuaTeXers, There's no such great opportunity as the wonderful conference BachoTeX in Poland to get your TeX projects done, getting hold of some handcrafting skills (book binding, calligraphy, ...) and to brainstorm your ideas with Hans, Luigi (and many others) while enjoying a cup of coffee, sunbathing or swimming in a lake, or just relaxing around a bonfire. Children and families welcome (even in the conference room). Link: http://www.gust.org.pl/bachotex/2016-en Be warned: the attendance is highly addictive :) Mojca ---------- Forwarded message ---------- From: Jerzy Ludwichowski Dear prospect BachoTeX participants and authors, the deadline for BachoTeX registrations has been extended to the 10th of April 2016, which means that no "late penalty" will be levied.

duplex printing and doublesided
by Pablo Rodriguez 04 Apr '16

04 Apr '16

Hi Hans, I have the following sample: \setuppagenumbering[alternative=doublesided] \setupinteractionscreen[option=portrait] \starttext No duplex printing. \page[right] In this document. \stoptext I’m afraid that doublesided alternative disables duplex printing. This would be a good reason to implement the features already asked at https://mailman.ntg.nl/pipermail/ntg-context/2016/084298.html. Many thanks for your help, Pablo -- http://www.ousia.tk

How to get the current section level?
by Lukáš Procházka 04 Apr '16

04 Apr '16

Hello, is there a (Lua) way how to get the current section level? Something like: ---- \def\GetCurrentSectionLevel{% % What to come here? } \starttext \chapter{Ch} \GetCurrentSectionLevel % Should yield "chapter" or e.g. 1 (meaning "chapter") \section{Sec} \GetCurrentSectionLevel % Should yield "section" or e.g. 2 (meaning "section") \subsubsection{SSSec} \GetCurrentSectionLevel % Should yield "subsubsection" or e.g. 4 (meaning "subsubsection") \stoptext ---- Best regards, Lukas -- Ing.

deprecated startMPenvironment
by Meer, Hans van der 04 Apr '16

04 Apr '16

Previously I could do the following \starttext \startMPenvironment[+]\switchtobodyfont[small]\stopMPenvironment \startMPpage % metafont code \stopMPpage \stoptext \endinput This is called by context --run --once etc. producing the figure and in this case modifying the font to a smaller size. Note, the context call occurs on the fly inside a \directlua{{os.execute(..)}. You may find this complicated, but it works for me and I would rather like not having to change may things all over the place. Now I learn from the ConTeXtgarden that startMPenvironment is deprecated and that I should use defineMPinstance and setupMPinstance instead. Thus I tried \defineMPinstance[mp:local][metafun][setups=mp:smallfont,textcolor=red] \startsetups mp:smallfont \switchtobodyfont[small] \stopsetups \startMPpage and also \startMPpage[mp:local] % metafont code \stopMPpage \stoptext \endinput But nothing happens. How do I get the effect earlier obtained with startMPenvironment without having to rely an a deprecated macro? Hans van der Meer

Dear Hans, Your sample works fine. This method gives me a flexibility of combining figures. BTW, I have one question. In the output, figure numbers started from 3, but suddenly jumped to 184. In a log file, metapost > initializing number mode 'scaled' floatblocks > '3' placed floatblocks > '4' placed floatblocks > '5' placed floatblocks > '6' placed floatblocks > '7' placed floatblocks > '8' placed floatblocks > '9' placed floatblocks > '10' placed floatblocks > '11' placed … floatblocks > '241' placed floatblocks > '242' placed floatblocks > '243' placed backend > xmp > using file '/Users/graph/ConTeXt/tex/texmf-context/tex/context/base/mkiv/lpdf-pdx.xml' pages > flushing realpage 1, userpage 1 pages > flushing realpage 2, userpage 2 pages > flushing realpage 3, userpage 3 pages > flushing realpage 4, userpage 4 pages > flushing realpage 5, userpage 5 pages > flushing realpage 6, userpage 6 pages > flushing realpage 7, userpage 7 pages > flushing realpage 8, userpage 8 pages > flushing realpage 9, userpage 9 pages > flushing realpage 10, userpage 10 pages > flushing realpage 11, userpage 11 I just curious why the number started from 3, and where are the numbers 4 - 182 omitted.

Dear All, there are broken links on several WIKI pages... In e.g. http://wiki.contextgarden.net/Protrusion there is http://source.contextgarden.net/font-ext.lua instead of proper one http://source.contextgarden.net/tex/context/base/font-ext.lua But when the latter link is clicked, instead of displaying the content I am getting: Internal Error - please restart the application! Links to MkII source I couldn't locate at all. A side note. Would it be possible to somehow grab Wiki content and verify if such links to TEX or LUA files exists? Thanks, Jan

Bug/change in fillinrules
by Mari Voipio 30 Mar '16

Hello, after I updated to about newest ConTeXt, I found out that \fillinrules doesn't work any more as expected, i.e. instead of filling the rest of the first line, the rule now starts on the second line, below the text that precedes \fillinrules. This doesn't match the behaviour indicated in http://wiki.contextgarden.net/Command/fillinrules . Is this a bug or should I change something in my code? Now I have \setupfillinrules [n=1, %one rule per command \fillinrules width=broad] %leaves some space between the text and the line \starttext \fillinrules{Refractometer serial no:} \fillinrules{Customer:} \fillinrules{Address:} \fillinrules{Fax:} \fillinrules{Email:} \fillinrules{Sample description:} \fillinrules{Solvent (water/other):} \fillinrules{Laboratory method:} \fillinrules{Date:} \fillinrules{Data collected by:} \stoptext The resulting pdf is attached.

Skipped figure numbers
by Aidan Nichol 30 Mar '16

30 Mar '16

I have been looking at various options for controlling how figures are placed on a page and based on answers to similar questions in this mailing list I tried various options. The most flexible one seems to be using tables e.g. \setupexternalfigures[location={default}] \starttext \placefigure[]{}{\externalfigure[hacker][height=1in]} \startxtable[frame=off,align=low] \startxrow \startxcell[ny=2] \placefigure[force][]{left twoup}{\externalfigure[mill][height=4in]} \stopxcell \startxcell \placefigure[force][]{the first}{\externalfigure[spider][height=1.5in]} \stopxcell \stopxrow \startxrow \startxcell \placefigure[force][]{the second}{\externalfigure[cow][height=1.5in]} \stopxcell \stopxrow \stopxtable It seems to work well except that figure numbers are being skipped. In this example hacker=1 mill=8, spider=9 and cow=10. Varying the contents of the table reveals that It is skipping two times the number of figures in the table. Is this an invalid combination of features I’m using or am I doing something wrong?

Nested floatcombinations
by Aidan Nichol 30 Mar '16

30 Mar '16

Based on answers to previous questions the easiest way to arrange figures on a page in a simple tabular arrangement is to use \startfloatcombination etc. and indeed works well I wanted to get a single tall figure on the left and two on the right above one another. I tried nesting i.e. \setupexternalfigures[location={default}] \definefloat[floatA][floatAs] \definefloat[floatB][floatBs] \setupcaption[floatA][number=yes,location=top] \setupcaption[floatB][number=no] \starttext \startplacefloatA[title={Using figures in nested float combinations}] \startfloatcombination[nx=2,ny=1] \startplacefigure[title={left two rows}] \externalfigure[mill][height=4in] \stopplacefigure \startplacefloatB \startfloatcombination[nx=1,ny=2] \startplacefigure[title={right top}] \externalfigure[spider][height=1.5in] \stopplacefigure \startplacefigure[title={right bot}] \externalfigure[cow][height=1.5in] \stopplacefigure \stopfloatcombination \stopplacefloatB \stopfloatcombination \stopplacefloatA \stoptext This just gave the three figures in a sort of single column down the page. Are nested floatcombinations not allowed or have I done it wrong?

adding font feature tnum in the TOC
by Willi Egger 29 Mar '16

29 Mar '16

Hi, hm, I am a little puzzled… If I am correct then one should be able to enable the font feature tnum for the page-numbers with “pagecommand=“. I have \setuphead [section] [aftersection=\page, textstyle=\bfd, numberstyle=\bfd, align=middle, after={\godown[-1\lineheight]}, number=no] \setuplist[section][pagecommand={\addfeature[tnum]#1\subtractfeature[tnum]}] However if I do this then I get the pagenumber prefixed with ‘section’ e.g. bbb bar buch bühne section3 What am I doing in the wrong way? Kind regards Willi

One of these can be avoided with a change in the setup for footnotes but not the other without destroying the layout of the footnote text. One problem is the way how context places the footnote number in front of the text, by default context uses the \llap command to move the number into the left margin but this prevents also the protrusion of the opening quote. You can avoid this problem when you change the footnote setup to \setupnotation[footnote][alternative=margin]. <example> \definefontfeature[default][default][expansion=quality,protrusion=quality] \setupbodyfont[modern] \setupalign[hanging] \showframe[text][text] \starttext »Text« \noindent\hbox to 0pt{}»Text« \noindent\hbox to 0pt{\hss}»Text« \stoptext </example> The second problem which prevents the opening quote to protrude are the struts which are added by context at the begin and end of the footnote content and there is no way to disable them because they are needed to have proper spacing between the individual footnote texts on the same page. <example> \definefontfeature[default][default][expansion=quality,protrusion=quality] \setupbodyfont[modern] \setupalign[hanging] \showframe[text][text] \starttext »Text« \strut »Text« \stoptext </example> In the example below where I took care of these two problems (don’t take care of \begstrut in this way in your real document because it will cause many problems, it’s just for educational purpose) to show you this is what caused the unwanted output. <example> \definefontfeature[default][default][expansion=quality,protrusion=quality] \setupbodyfont[modern] \setupalign[hanging] \showframe[text][text] \setupnotation[footnote][alternative=margin,align=hanging] \starttext \let\begstrut\relax First Footnote.\footnote{»\input{ward}«} Second Footnote.\footnote{»\input{ward}«} \stoptext </example> Wolfgang

Footnote markers
by Robert Krug 26 Mar '16

26 Mar '16

Greetings, Is there a way to attach a footnote marker to the text following the footnote, rather than to the text preceding? That is, given something like: Some text \footnote{note.} more text. I would get (using an asterisk here, but that is not important): Some text *more text. rather than: Some text* more text. I am trying to re-typeset a couple of documents from circa 1600 where it is done that way. Many thanks for Context. It is quite nifty. Robert

I've tried it in the following example, but there is another problem from page 58 - blank line. But my TeX interpretation of the above pseudo code may be inappropriate... you can see what glue eventually is used with: \showmakeup[glue] \start \parfillskip 123pt \relax \input tufte \par \parfillskip 123pt plus 1fil \relax \input tufte \par \parfillskip 123pt \relax \input tufte \par \parfillskip -123pt plus 1fil \relax \input tufte \par \stop ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Greetings, Is it possible to have \starttext \startchapter Hey a chapter! \startsection something.one \startsection someting.one.one \startsection something.one.one.one \stopsection \stopsection \stopsection \stopchapter \stoptext render as: 1. Hey a chapter! 1.1 something.one 1.1.1 something.one.one 1.1.1.1 something.one.one.one Thanks, Mica

It is a hard job to understand how all works ... I tried to create the first example of the documentation "Page 257 Anchors and layers", but failed with mkii and iv. The page is created, but without the graphical elements. Not using \startbuffer--\stopbuffer makes no difference. MTXrun | current version: 2010.07.30 11:35 Herbert \starttext \section {Anchors and layers} \startbuffer[a] \setMPpositiongraphic{X-1}{mypos:arrow}{to=X-2} \setMPpositiongraphic{X-2}{mypos:arrow}{to=X-3} \stopbuffer \startbuffer[b] In a previous section we saw that some \hpos {X-1} {words} were \hpos {X-2} {circled} and connected by an \hpos {X-3} {arrow}. As with most things in \CONTEXT, marking these words is separated from declaring what to do with those words. This paragraph is keyed in as: \stopbuffer \getbuffer[a,b] \stoptext

Why does 0.0001pt make such a big difference?
by Peter Münster 24 Mar '16

24 Mar '16

Hi, Please compare \setupwhitespace[0.0001pt plus 2ex] with \setupwhitespace[0pt plus 2ex] here: \showframe \setuphead[section][style={\switchtobodyfont[72pt]}] \setupalign[height] \setupwhitespace[0.0001pt plus 2ex] % desired result %\setupwhitespace[0pt plus 2ex] % "plus 2ex" is unused \starttext \dorecurse{5}{\dorecurse{150}{bla }\par} \section{test} bla \stoptext Why is there such a difference please? TIA, -- Peter
