Widgets color option not working with Mark IV
by Reviczky, Adam 31 Jan '11

31 Jan '11

>>it was not yet implemented (passing the info was, but not adding it to >>the pdf stream) >> >>i uploaded a new beta Thanks, color and fontsize works perfectly now! Could you also have a look at whats going on with the alignment to the first field? And since we're at it, I can't get the field+javascript working with mkiv, is that suppose to work? All I want to do is the accented glyphs in a text field, aka: \setupfield [TextSetup][...][...][...] [...., regionin=JS(Initialize_TeX_Key), afterkey=JS(Convert_TeX_Key), validate=JS(Convert_TeX_String)] Works with mkii, but has no effect with mkiv. Thanks again, Adam

Hello, This used to work with pdftex: \starttext \input "\string|echo hello world" \stoptext What's the recommended way, to do this in mkiv?

wrong page with \finishregisterentry
by Steffen Wolfrum 30 Jan '11

30 Jan '11

Hi, when \finishregisterentry is set within a paragraph then the "lastrealpage" gets the value from the page where this respective parapgraph starts. (In the example below it is 4 instead of 5.) That is quite sad when you have long paragraphs. How can I set a register range telling me lastrealpage is exactly the page where the ending mark is set? Attached you may find a minimal example. Best, Steffen ------- \starttext \switchtobodyfont[50pt] \input tufte \par \setregisterentry[index][label={Index_Label}]% Test\dorecurse{5}{This is are words, not paragraphs. }\finishregisterentry[index][label={Index_Label},entries={Index entry}] Test \stoptext

Header problem
by Keith McKay 30 Jan '11

30 Jan '11

Dear All I have a problem with a chapter title which I am using as a header. The title's length in the header is such that it extends into the page margin. I would have thought that the text would have stayed within the header area and gone on to a second line but this does not happen. I have been on the wiki looking at the command reference syntax for \setupheader and \setuphead and \setupheadertexts to try and solve this problem but I'm a bit stuck understanding the syntax. Reducing the amount of text in the chapter name isn't an option. Any other suggestions Keith McKay

strange interaction with footnote and section
by Florian Wobbe 30 Jan '11

Hi, I have a strange problem with footnotes, when interaction is turned on. When a footnote is followed by a \section{}, the color of the first footnote number will change from contrastcolor to color. Also the number is not a clickable link anymore. Of cause the footnote is not on a different page. The more \section{}s you have, the more footnote interaction links will vanish: \setupinteraction[state=start] \starttext 1st\footnote{first}, 2nd\footnote{second}, 3rd\footnote{third}, 4th\footnote{fourth}, 5th\footnote{fifth}. % uncomment these one at a time: %\section{First} %\section{Second} %\section{Third} \stoptext

Head: why different distances?
by Procházka Lukáš Ing. - Pontex s. r. o. 29 Jan '11

29 Jan '11

Hello, I created a simple file which derives head style 'subsectionX' from 'subsection'.

Comment on new "Page Design" Chapter for new manual.
by John Culleton 28 Jan '11

28 Jan '11

The question of page dimensions can be very confusing for the raw beginner. I suggest the something like the following as a lead in: ----------------------------------------------------------- For a printed page we really have to deal with three different sets of dimensions. The body of the text exclusive of headers, footers etc. is called the type block. In TeX the measurements of the type block are called \hsize and \vsize. When text is being laid out each paragraph is generally no wider than the \hsize and when \vsize is exceeded the page is ended and a new one is started. The actual page size of the finished document is measured with \pdfpagewidth and \pdfpageheight. For most documents this is the last set of dimensions needed. In a few cases "camera ready copy" is required which means that the final printed page image is centered on a larger piece of paper stock, often with trim marks indicating the boundaries of the page size. For example here are the dimensions for a book recently printed: hsize =4.25 in vsize =7 in pdfpagewidth = 6 in pdfpageheight = 9 in stockwidth = 8.5 in stockheight = 11 in. ----------------------------------------------------------------------------------- The terminology may need some refinement but you get the idea. Think of the "Man from Mars" encountering Context and even TeX for the first time. -- John Culleton Create Book Covers with Scribus: http://www.booklocker.com/p/books/4055.html Typesetting and indexing http://wexfordpress.com book sales http://wexfordpress.net Free barcode: http://www.tux.org/~milgram/bookland/

reference tag for equations.
by Jeong Dalyoung 27 Jan '11

27 Jan '11

Dear all, 1. I have used \startalign many times before without tag and it worked well. Thanks Aditya. now, I tried to set a tag for an equation using \NR[+]: But there is no reference numbers in the output. Since there is no mention about this problem in the list, I think that it is my only problem, Should I do something special for this? \starttext \startformula\startalign[align={middle, left}] \NC x \NC = n\times r, \NR[+] \NC y \NC = {{n-1}\choose {r-1}}, \NR[+] \NC z \NC = (n-1)\times {r}, \NR[+] \stopalign\stopformula \stoptext 2. Is there a command to reduce the width of the space between letters? For some Korean fonts, the space between letters is a little bit wide. I think that it is not a simple command, it may be very difficult job for me. However, is there a way to do that? My system is Mac OSX 10.6, ConTeXt Minimal ver: 2010.11.12 18:22 MKIV.

new beta
by Hans Hagen 26 Jan '11

26 Jan '11

Hi, I uploaded a new beta. The most important changes are: - Environments and modules are no longer loaded under protection so this has to be done explicitly in the files themselves. So far we haven't encountered problems with that change. - Some more cont-*.tex files have been split in mkii and mkiv versions. In mkii a tex file is loaded when no mkii file is found, but in mkiv only files with suffix mkiv are loaded. That way we stay compatible. This also means that cont-sys.tex is no longer loaded in mkiv which is okay as normally nothing in there concerns mkiv. If you use that file for setting up for instance another default paperformat, you'd better create a cont-sys.mkiv file. (Maybe that file should go and we should use the configuration file instead.) - The multilingual interface and messages are now loaded at the \LUA\ end. If you observe problems, please let me know. - If you are adventurous you can add the following to cont-new.mkiv \enablemode[*nofonts] This will postpone font loading and will be default soon. This saves runtime when you use another font than latin modern. When no font is loaded before the first \starttext, modern will kick in. A side effect is that any text typeset before \starttext will not show up in the output. If you observe that, you need to setup a bodyfont explicitly beforehand. In practice there should be no problems. The delayed loading is somewhat tricky but has been tested for a while. - There have been some fixes to linebreaks in verbatim. Hopefully I didn't mess things up too much. - An upcoming version will also have \nonknuthmode as default. You can test this by putting this macro in cont-new.mkiv.

Hi, I was playing a bit more with the field style properties and found out that if the font size is always different it works, but as soon as it has a size that was used before it defaults back to normal. Here's the minimal example: % begin of example \starttext \setupfields [label,frame,horizontal] [offset=4pt,height=fit,framecolor=green,background=screen,backgroundscreen=.80] [height=40pt,width=100pt,align=middle,background=screen,backgroundscreen=.90,frame=off] [height=40pt,width=100pt,color=red,align=right,style=type,background=screen,backgroundscreen=.90,frame=off] \setupfield [sizea] [horizontal] [style={\switchtobodyfont[20pt]}] \setupfield [sizeb] [horizontal] [style={\switchtobodyfont[28pt]}] \setupfield [sizec] [horizontal] [style={\switchtobodyfont[20pt]}] \definefield [Emaila] [line] [sizea] [] [pragma(a)wxs.nl] \definefield [Emailb] [line] [sizeb] [] [pragma(a)wxs.nl] \definefield [Emailc] [line] [sizec] [] [pragma(a)wxs.nl] \field [Emaila] [your email] \par \field [Emailb] [your email] \par \field [Emailc] [your email] \stoptext % end of example (field of Emaila has fontsize 20pt as defined, field of Emailb has fontsize 28pt as defined, but field of Emailc defaults back to normal 12pt? size instead of the defined 20pt. See attached pdf.) As for the color option, I couldn't figure out why it's not working at all. Some hints appreciated. Best wishes, Adam

Minimals/MTXrun: 32-bit system with 64-bit kernel: `MTXrun | no 'texmf-linux-64'`
by Paul Menzel 26 Jan '11

26 Jan '11

Dear ConTeXt folks, I am running a 32-bit system with a 64-bit kernel. So relying on uname -m to determine the architecture leads to problems [1]. So I do `cpu = "i686` manually in `first-setup.sh` but I still do get the the following error message. sent 1145 bytes received 8908331 bytes 774737.04 bytes/sec total size is 31230200 speedup is 3.51 MTXrun | mtx update: updating mtxrun for linux: rsync -tgo --chmod=a+x /opt/context/tex/texmf-context/scripts/context/lua/mtxrun.lua /opt/context/tex/texmf-linux/bin/mtxrun MTXrun | run: rsync -tgo --chmod=a+x /opt/context/tex/texmf-context/scripts/context/lua/mtxrun.lua /opt/context/tex/texmf-linux/bin/mtxrun → MTXrun | no 'texmf-linux-64' under tree /opt/context/tex When you want to use context, you need to initialize the tree by typing: . /opt/context/tex/setuptex `first-setup.sh` executes the following command # download or update the distribution # you may remove the --context=beta switch if you want to use "current" mtxrun --verbose --script ./bin/mtx-update.lua --update --make --force --engine=all --context=beta --platform=$platform --texroot=$PWD/tex $@ but `mtxrun` or `mtx-update.lua` does not seem to honor the option `--platform` all the way.

Hi, The alignment doesn't apply anymore to the first field (widget) in the latest beta. Here's the minimal example: % begin of example \starttext \setupfield [ShortLine] [label,frame,horizontal] [offset=4pt,height=fit,framecolor=green,background=screen,backgroundscreen=.80] [height=18pt,width=80pt,align=middle,background=screen,backgroundscreen=.90,frame=off] [height=18pt,width=80pt,color=red,align=right,style=type,background=screen,backgroundscreen=.90,frame=off] \definefield [Email] [line] [ShortLine] [] [pragma(a)wxs.nl] \startalignment[middle] \field [Email] [your email] \par \field [Email] [your email] \stopalignment \stoptext % end of example works with: beta 2011-01-24 (see attached pdf) doesn't work with: beta 2011-01-25 (see attached pdf) Best wishes, Adam

Using \pdfnames and friends.
by Paul Isambert 25 Jan '11

25 Jan '11

Hello, I'm trying to use \pdfnames with MkIV, but I can see from the sources that it's a no-op and should be replaced with \pdfbackendsetname. So I use \pdfbackendsetname{EmbeddedFiles}{22 0 R}, trying to achieve the same thing as \pdfnames{/EmbeddedFiles 22 0 R}, but "22 0 R" is surrounded by parentheses, as if it were a PDF string, so that I end up with the useless "/EmbeddedFiles (22 0 R)". Similarly, \pdfbackendsetcatalog{PageMode}{/UseOutlines} produces "/PageMode (/UseOutlines)". What am I doing wrong? Best, Paul

Layers by native code vs. by Lua
by Procházka Lukáš Ing. - Pontex s. r. o. 25 Jan '11

25 Jan '11

Hello, a weird thing happens when setting up layers - I'm getting different results depending on whether setup is performed by native Ctx code or by Lua: --- \setuppapersize[A4,landscape][A4,landscape] \setuplayout[page] \definelayer[T][x=10mm,y=0mm] \startuseMPgraphic{VerticalRule} draw (0,0)--(0,PaperHeight) withcolor red; \stopuseMPgraphic \startsetups S1 \setlayer[T]{\useMPgraphic{VerticalRule}} \stopsetups \startluasetups S2 \startluacode context.setlayer({"T"}, "\\useMPgraphic{VerticalRule}") \stopluacode \stopluasetups \starttext \setupbackgrounds[page][setups=S1,background={T}] \page[empty] \setupbackgrounds[page][setups=S2,background={T}] \page[empty] \stoptext --- Both setups (S1 and S2) should do the same - to draw a vertical line to the full height. The first case (S1) is OK - the line starts 10 mm from the top left corner of the page. The second case (S2) is somehow shifted - the line starts cca 13 mm from the top left corner of the page. What is the reason? And how to make Lua way give the same result? Best regards, Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.

Problem calling Lua during \startsetups
by Procházka Lukáš Ing. - Pontex s. r. o. 25 Jan '11

25 Jan '11

Hello, I encountered a bit weird thing when I used Lua in \startsetup: --- \definelayer[T][x=0mm,y=0mm,width=\paperwidth,height=\paperheight] \directlua{n, m = 1, 11} % Initialization \startsetups layer % In my real code (= not in this example) % the value of 'n' is used here to set the appropriate background, % = n-th page of a PDF, and also to draw a filled rectangle on % the left or right side (depending on whether n is even or odd) % The code bellow fails [1] \startluacode print("N=", n) if n == 2 then else end \stopluacode \stopsetups \setupbackgrounds[page][setups=layer,background={T}] \starttext % The code bellow works well [2] \startluacode print("M=", m) if m == 2 then else end \stopluacode \dorecurse{4}{\page[empty]} \stoptext --- The problem is that Lua code between \startsetups ... \stopsetups [1] seems to be "parsed" another way than when in [2]. The [1] gives the following error message: --- ! LuaTeX error <main ctx instance>:1: 'then' expected near 'thenelseend'. --- So it seems like <space>s and/or <\n>s were "ignored". If you commented [1], the section [2] would work well. So how to use make Lua work well even between \startsetups ... \stopsetups? Best regards, Lukas -- Ing.

by Wolfgang Schuster 25 Jan '11

Hi, \stopasciimode does always switch to \donknuthmode what is nonsense when \nonknuthmode will be the default in the future, wouldn’t something like this make more sense \unexpanded\def\stopasciimode {\popcatcodetable \ifconditional\knuthmode\else\donknuthmode\fi} and set \knuthmode to true and false with \every(don|non)knuthmode.

template for protocol (record) of experiment
by Paul Menzel 25 Jan '11

25 Jan '11

Dear ConTeXt folks, does anyone of you use(d) ConTeXt for typesetting a protocol/record of an experiment (in my case physics, but it should not matter). I already found the sample documents in the Wiki [1] and probably will be able to come up with something, which would take me some time. So I thought I’d be clever and ask you professionals if you have some templates, especially for the title page, since you probably already found a good font and the right settings for this purpose. There are no real requirements. The name of the university [2], with the logo, the name of the supervisor, the student with the student number, date and the topic (Versuchsprotokoll). Thanks in advance, Paul [1] http://wiki.contextgarden.net/Sample_documents [2] http://www.physik.hu-berlin.de/

Too many open files
by Thomas Floeren 24 Jan '11

24 Jan '11

Hi, with the actual minimals and luatex on Mac OSX I get "pdfError: Couldn't open file <image file name> Too many open files" and then fatal error 70. With an older installation everything is ok, minimals on Windows are ok, too. The document has about 700 figures. En detail: Working: OSX: context 2010.10.14 13:14; luatex (64) beta-0.63.0-2010091123 Working: Win XP: context 2011.01.24 10:00; luatex (32) beta-0.65.0-2010121421 Not working: OSX: 2011.01.24 10:00; luatex (64/32) beta-0.65.0-2010121316 Is this a known problem? Thanks for any help. Kind regards Thomas

Labels in MetaPost (MetaObj)
by Stefan Müller 24 Jan '11

24 Jan '11

Hi list, I'm having some trouble with MetaPost in general and MetaObj in particular. I hope someone on this list can assist me here. I'm trying to run the appended ConTeXt file with a quite simple object "Segment" (from the manual [1], section 2.1). This script works fine as it is. I wanted to add a simple TeX label ("\tt \overbar{E}") to the drawing macro, but failed. When including the line marked with "% 1" the TeX run fails. I don't understand why. The line with "% 2" is taken frome the metaobj manual (section 5.8) [1], but including this doesn't work either. It would be great if someone could tell me what's wrong with the mp-code below and explain how to place a (TeX) label inside a metaobj object. Thanks in advance, Stefan. [1] http://tex.loria.fr/prod-graph/momanual.pdf PS: Both variants fail with mp error messages like this: "mplib > mp terminal: ! Inconsistent equation (off by 1). <to be read again> ; assignObj->(SUFFIX0)=incr(nObj_); iname_[(SUFFIX0)]=str(SUFFIX0);addclass_((S... newSegment->...roup.assignObj((SUFFIX2),"Segment") ;ObjPoint.a,b;ObjCode"@##b... <to be read again> ; <*> ...ar {E}") shifted n.a; enddef; newSegment.s; s.a=origin; drawObj(s); ; !
