macro beginner question...
by Bernhard Rosensteiner 05 Jun '10

05 Jun '10

Hello all, in the process of learning macro programming in context i encountered the following problem (minimal example is attached): when i have \setuphead[section][color={red}] the color key influences in a strange way my „novice macro“ (see the text which should be black but is red). Further more the \ruledhbox in my macro stops at some point the red color (with a normal \hbox all the text in the section is red). what i´m doing wrong here? best regards Bernhard

(Hongwen Qiu) hi hongwen, thanks for taking an interest. my initial post had a mistake: i meant to refer to the /Metafun/ manual, not the Metapost manual. that probably didn't help. i guess what i should have said is, i know that pxy can give me the bounding /box/ (the rectangle with the maximum horizontal and vertical extents of its contents, be they set in horizontal or vertical mode), but can it give me the subset of that, the bounding /path/, if you will, when the contents are text which flows over several lines. the bounding /path/ may not be rectangular, although it will be something like the union of the bounding boxes of the text's individual lines. i think if you look at the correct reference, the difference of the effects is clear. i think the challenge is that you don't know where the line breaks will occur until you typeset it. --adam

Wrong spacing before and after commas in math(?)
by "Stefan Müller" 04 Jun '10

04 Jun '10

Hi, if I'm typesetting for example $(a,x,\dots,b)$ I see that the space before the x is too small. It should be bigger than the space after the x. I could work around it by typing $a,\,x,\dots,\,b$ but this is somewhat inconvenient and even a bit too much spacing... On the other hand, the spacing before \dots is just right, but the spacing after \dots is too small: the spaces between commas and periods ",...," should all be the same. Is this a bug? Can this be changed by a global option or something? Thanks for any help in advance.

XITS Math font - first beata
by Khaled Hosny 04 Jun '10

04 Jun '10

As promised, the OpenType MATH enriched version of STIX fonts, XITS, is now available. This early version provides: * OpenType math constants values, necessary for proper layout of various math elements. * proper math accent positioning. * proper sub/superscript positioning (not fine tuned yet). * extensible radicals, delimiters and math accents. * oldstyle figures. * some pre-composed fraction. Tarball can be downloaded from: http://github.com/khaledhosny/xits-math/downloads Feature requests, bug reports and fixes, should be directed to the issue tracker: http://github.com/khaledhosny/xits-math/issues Against the practice of STIX project, this version have not been extensively tested, only few basic tests through ConTeXt MkIV were done. Instead, in the spirit of open development model, I'm releasing early and often and trusting that thee are many people with more knowledge of math aesthetics and sharp eyes to spot error better than what I can ever do. Others are highly welcomed to test against other OpenType MATH implementations, namely unicode-math (with both XeTeX and LuaTeX) and MS Office 2007 and higher.

Slides: uncover things piecewise
by Marco 04 Jun '10

04 Jun '10

Hi, I use the »simpleslides« module for a presentation and I wonder if it is possible to uncover things piecewise. Take the following example: \usemodule [simpleslides] \starttext \SlideTitle {My Topic} \startitemize \item First % Visible by default \item Second % Gray by default \item Third % Gray by default \stopitemize \stoptext I want to achieve the following: The first item should be visible by default. The second and third items are not visible or grayed out. The by jumping to the (physically) next slide (for the audience it's still the same page) the second item will be displayed and so on... I've found some old pieces of code in the mail archive but didn't get it to work. Kind regards Marco

\MPpos, pxy, initialize_box(), oh my!
by Adam Fuller 04 Jun '10

04 Jun '10

hello all, i finished a presentation (my first ConTeXt creation!), and now i've got a couple days to get creative again. i'm trying to understand how the typeset lines of text in the MetaPost manual were outlined in Section 5.1. i've just discovered that \MPpos only seems to work in MPpositiongraphics, and initialize_box sets `pxy' to \hpos's contents bounding box. what if you want pxy to be not strictly a rectangle, but the path that encloses text, etc., which is just part of flowing text in a paragraph, like page 247 (beginning of Positional Graphics chapter) in the MetaPost manual? i've read the MetaPost manual. i hope the answer isn't too obvious. thanks, adam

"Please fill out the following form"
by Michael Saunders 04 Jun '10

04 Jun '10

I was creating a document with many hyperlinks and tooltips, and everything was working, until it reached a certain size. Two strange behaviors began: 1. At the top of Adobe Reader I get a purple band that says "Please fill out the following form..." 2. Tooltips no longer appear at the first rollover. Instead, a pale blue box with a checkmark pops up. On the second rollover, my tooltips appear as normal. Is this some limit inherent in Context, pdf, or Adobe Reader? Is there a way to work around it?

OSFONTDIR
by Mojca Miklavec 03 Jun '10

03 Jun '10

Dear Hans, Some time ago the following code was working. On Mac it seems to have no influence now (OSFONTDIR doesn't get "fixed"), but if I set it in environment to the same string, it works. local function check_configuration() -- not yet ok, no time for debugging now if os.env["OSFONTDIR"] then -- ok elseif os.type == "windows" then os.setenv("OSFONTDIR","c:/windows/fonts//") elseif os.type == "macosx" then os.setenv("OSFONTDIR","$HOME/Library/Fonts//;/Library/Fonts//;/System/Library/Fonts//") end end Can it be that setenv doesn't really set anything (it just sets it locally to some variable) and then resolvers only look for proper environmental or texmf.cnf variables? I have an impression that that function has been removed from LuaTeX a while ago, but I may be wrong. Mojca

Re: [NTG-context] Multiple pleas for help (long)
by Scott Steele 02 Jun '10

02 Jun '10

If anyone has any insight on how to keep the footnotes from having their numbers in the margin and from having line-breaks after each one, that is the only issue from the original email that is still unsolved, I think. ——— In Latex, \fancybreak was part of a package called, I believe, fancyheader or fancypage. It produced a break frequently seen in published prose (I'm currently reading {\em Bluebeard} where Kurt Vonnegut uses it liberally) with significant vertical space between two paragraphs and, centered both in that vertical space as well as horizontally, a number of well-spaced marks. There are usually 3 marks, and they are frequently asterisks or traditional dingbats/fleurons. This sort of break is generally used when the author wishes to indicate a break more significant than a change in paragraph but short of an outright new chapter. \def\FancyBreak{\par\blank\hfill* * *\hfill\hfill\par\blank} \starttext \input tufte \FancyBreak \input tufte \stoptext I don't understand why I need the two consecutive \hfill's at the end for the marks to be centered, but the definition works well for me. ——— Thanks, Wolfgang, for your help with the emoticons—they work now. \useexternalfigure[frowny][Frowny][factor=8,type=pdf] \def\Frowny{\dontleavehmode\smash[h]{\externalfigure[frowny]}} Also, thanks for the \simplealignedbox, which works very well in my table of contents (although I have to put a \par at the end of it or it stays on one line and goes off the page). I don't understand why, but Tex didn't like having a \par inside the type of definition you used, but it allowed the following: \def\SectionListEntry#1#2#3% { \noindent \simplealignedbox{left}{2cm}{#2}% \simplealignedbox{middle}{5mm}{·}% \simplealignedbox{right}{3cm}{#3}% \par } (I have a few issues with my table of contents, but these are now less specific to \placelist, so I'm including them in a different posting.)

Indents, enumerations, and modes (mk2+mk4)
by Matthias Weber 02 Jun '10

02 Jun '10

Dear all, I have two questions regarding using spacing in enumerations. Depending on a mode being enabled, I would like to add a command at the beginning of an enumeration (I want to place something in the margin, but it doesn't actually matter what I do, only when). As shown in the minimal example below, invoking the macro that does something, a little extra space is added. I don't know why, it is probably something very TeX-basic I am ignorant of. So: How do I get rid of the extra space? The problem occurs both in mk2 and mk4, I would prefer a solution that also works in mk2. Thanks!

BibLaTeX
by Peter Park Nelson 01 Jun '10

01 Jun '10

I frequently use LaTeX with BibLaTeX and the BibLaTeX-Chicago Style package to typeset scholarly material. For me, BibLaTeX is a great tool. However, I am attracted to ConTeXt because, coming from a desktop-publishing background, ConTeXt gives me more/easier control over document layout and structure. Thus I began to dream of a "chocolate + peanut butter" combination of the two. I would like to know if anyone has thoughts on the possibility of using BibLaTeX & Biber with ConTeXt -- perhaps through a wrapper module of some kind? I don't understand the internals of LaTeX or ConTeXt well enough to know if this is a ridiculous question. I respect the ConTeXt Bib module, but BibLaTeX-Chicago offers exactly what I'm looking for. Both BibLaTeX and ConTeXt use e-TeX, and the internals of BibLaTeX appear not to be LaTeX-specific. So, would it be possible to write a ConTeXt module that bypasses Bib and provides an interface between ConTeXt bibliography commands and BibLaTeX/Biber? Thanks, PPN

Strange expansion behavior in XML/luatex
by Martin Kolařík 01 Jun '10

01 Jun '10

Hello, I had a problem with some my documents; I extracted it to as small code as possible. What is happening -- if any of xml flushing function (I tried xmlflush, xmlfilter and xmlall) is expanded to a macro (so the content of xml becomes a text of the macro), and the xml contains other hooked xml tags, the \edef (and its counterparts \xdef or \expandedaction) inside the inner tag is "skipped" by the log. Then macros relying on the expansion fail (I detected it in \doif and \processaction). Macros are normally expanded, only \edef fails (maybe some other TeX commands fail too, but I did not test it). In my example below, content of "il" is flushed to a macro, "inline" is the inner tag and "\processaction" is the example of macro using "\edef". Do not look for sense, it is an example. XML: <?xml version="1.0" encoding="utf-8"?> <il> Text <inline what="something" /> text. </il> TeX: \startxmlsetups doc:inline \processaction [\xmlatt{#1}{what}] [something=>A thing, nothing=>Hic sunt leones] \stopxmlsetups \startxmlsetups doc:il \edef\content{\xmlflush{#1}}% \stopxmlsetups \xmlregistersetup{xml:doc} \startxmlsetups xml:doc \xmlsetsetup{\xmldocument}{inline|il}{doc:*} \stopxmlsetups I do not know, if it is a bug or a feature :-); but notwithstanding the fact, similar code I used in MkII worked very well.

Title page layout
by Scott Steele 01 Jun '10

01 Jun '10

I'm trying to anchor a table or box containing my title and subtitle to the bottom right corner of the textblock (on a title page). The following comes very close to doing what I want, but there is still some vertical space between the bottom of the text of the subtitle and the last major horizontal gridline. How can I have the subtitle text be (above and) flush with the last major horizontal gridline in the same way that it is flush with the rightmost vertical gridline? NOTE: Small adjustments to the example I provide might not be helpful for me since, in actuality, I'm using Adobe Jenson, which makes both the metrics and the expression of the problem slightly different.

Frontmatter page numbers and using ifodd / pageno
by Scott Steele 01 Jun '10

01 Jun '10

With the page layout setups I'm using, the first table of contents entry on each page (except for the first page) is formatted as if it were on the preceding page. I assume that the page number is not advancing until some number of objects are placed on the page. When I compiled the example included below, it was the first three entries on each page (after the first page) that were formatted as if they were on the previous page. Related to this, I need "invisible" page numbers on the table of contents pages to enable different formatting by odd/even page number (which I accomplish now by using \phantom as a style command for page numbering), but I'd like for the page numbering of the body matter to start at 1. Also, how can I number the front matter backward? Like: xi, x, ix, viii, vii, vi, v, iv, iii, ii, i. \def\SectionListEntry#1#2#3% { \noindent \noexpand{\ifodd\pageno \simplealignedbox{left}{.63667\textwidth}{#2} \simplealignedbox{middle}{.06\textwidth}{·} \simplealignedbox{right}{.30333\textwidth}{#3} \else \simplealignedbox{left}{.30333\textwidth}{#3} \simplealignedbox{middle}{.06\textwidth}{·} \simplealignedbox{right}{.63667\textwidth}{#2} \fi} \par\blank } \setuplist[section] [alternative=command, command=\SectionListEntry] \def\TableOfContents% { \page[empty] \page[odd] \setuppagenumbering[style=command, command=\phantom] \setuppagenumber[state=start] \placelist[section] \setuppagenumber[state=stop] \page[empty] \page[odd] } \startfrontmatter \TableOfContents \stopfrontmatter \startbodymatter \setuppagenumber[state=start] \dorecurse{45}{\section{Section title}\input tufte} \stopbodymatter Thanks, Scott ----- This is a work of ﬁction.

Difference in whitespace around section head from mkII to mkIV

hi all, i'm experiencing some unwanted whitespace related to a section head. the whitespace is present when using lua (texexec --lua funk.tex) and absent when using mkII (texexec funk.tex). i've confirmed the correct mkII behaviour on the garden's live tool, and my own minimals installation: This is LuaTeX, Version beta-0.60.1-2010050621 (rev 3678) \write18 enabled.

luatools not finding files in TL 2010
by Mojca Miklavec 31 May '10

31 May '10

Hans, if I run mtxrun --script patterns --convert on TeX Live 2010 it stops working with cannot open : No such file or directory #1 feature request: it would be nice to have a slightly more informative feedback The problem appears in the following line: function scripts.patterns.prepare() dofile(resolvers.find_file("char-def.lua")) end inside mtx-patterns.lua since apparently luatools doesn't find char-def.lua > luatools char-def.lua [no response] > kpsewhich char-def.lua /Users/mojca/soft/texlive/2010/texmf-dist/tex/context/base/char-def.lua [kpsewhich finds the file] In ConTeXt minimals this works fine. #2 bugfix request: any idea why it fails or how to fix it? Thanks a lot, Mojca

For me, it looks rather like a bug, not a feature :) In the installer, I need to setup PATH variable before executing the real script, and this thing bothers me. -- Best Regards, Vyatcheslav Yatskovsky

Syllabus title page (newbie problems)
by Vyatcheslav Yatskovsky 31 May '10

31 May '10

Hi, I'm making my syllabus title page with standard "bureaucratic" elements, like signature stamps, etc. Please, look at the attached png file for idea how it should look like. I started new page using \startstandardmakeup, which centered the text too. But I have problems with signature: how to reset the alignment to left, and, more important, how to place two \fillinrules in one line of text ("_day_"_month_ year)? Now my script looks as follows: ----------------------------------- \setupbodyfont[mscore,rm,14pt] \usemodule[fullpage][style={cm,headings}] \starttext \startstandardmakeup[doublesided=no,align=center,style={\switchtobodyfont[ss,18pt]}] \setupbackgrounds[header][text][background=] \setupindenting[none] \setupinterlinespace[28pt] % \let\\=\blank {\bf NATIONAL AVIATION UNIVERSITY} INSTITUTE OF ELECTRONICS AND CONTROL SYSTEMS Airspace control systems faculty Aviation computer-integrated complexes department \startstandardmakeup[align=left] %is there better command for this? \setupnarrower[left=12cm] \startnarrower[left] "Approved" Deputy Rector for Academics \fillinrules[]{}{A.Polukhin} \fillinrules{"}{"}\fillinrules[]{}{\currentdate[year]}\par %have problem here: need to keep two rules on one line \stopnarrower \stopstandardmakeup \par\vfill {\tfx Kiyv \currentdate[year]} \stopstandardmakeup \stoptext -- Best Regards, Vyatcheslav Yatskovsky

The default setup for \part has the empty value for placehead and to show the content you have to set \setuphead[part][placehead=yes] Wolfgang

Windows Minimals installer is broken -- mtxrun does not work
by Vyatcheslav Yatskovsky 31 May '10

31 May '10

Hello everybody and esp. Mojca, I started updating my Windows installer code to include "--extras" switch. Unfortunately, I found that mtxrun.cmd does not exist anymore and is replaced by mtxrun.exe. Moreover, mtxrun.exe is not working at all, complaining "mtxrun: unable to locate texlua.exe on the search path", while texlua.exe is present in the same folder! Please, help me fix this issue, because installer is broken for the moment. Regards Best, Vyatcheslav

LuaTeX error ... object in use
by Michael Saunders 31 May '10

31 May '10

I keep running into errors that look like this: ! LuaTeX error ...imal/tex/texmf-context/tex/context/base/lpdf-ini.lua:345: pdf.immediateobj() object in use I can't find anything specific that's causing them. For example: input{chapter1} input{chapter2} fails, but: %input{chapter1} input{chapter2} and input{chapter1} %input{chapter2} work. Or, I may make a small change, get the error, reverse the change, and continue to get the error. Maybe I need to allocate more memory somehow? what's wrong?

setups in typescripts
by Bernhard Rosensteiner 31 May '10

31 May '10

Hello, i have made a typescript which works. the only thing is that i have in my typescript something like: \startsetups [fallbackfonts] … \stopsetups \starttypescript [bla] \setups[fallbackfonts] … \stoptypescript referring in my document to the typescriptfile with \usetypescriptfile[Mytypescript] does not load the setups and so the font fallback is not working (obviously \usetypescriptfile only loads the typescripts). When i do: \input Mytypescript in the document all works as expected. So my question is how can i load setups with \usetypescriptfile Maybe i have to make a extra „fontfallback-setups“ file, but i don´t know how it is recognized by context. Please help. best regards Bernhard

unicode subscripts
by Yury G. Kudryashov 30 May '10

30 May '10

Hi! Unicode subscripts do not work (at least, in math): \starttext $a₀₁₂₃₄₅₆₇₈₉₋₌₊$ \stoptext prints only "a". The file char-def.lua contains block like this: [0x2080]={ category="no", description="SUBSCRIPT ZERO", direction="en", linebreak="al", specials={ "sub", 0x0030 }, unicodeslot=0x2080, }, Which file should handle this "specials={ "sub", 0x0030 }"? P.S.: Superscript digits work. Probably, the font contains ¹ but not ₁.

MkIV, XML and raw TeX input
by Martin Kolařík 28 May '10

28 May '10

Hello, I have found a problem when switching from MkII to MkIV -- I am using a XML containing raw TeX (a temporary solution for math, which lasts for four years now) and now, in MkIV, I did not succeed to adopt TeX anyhow. The math is typeset in math style, but obviously characters read from XML have improper catcode set. I tried some tricks with \scantokens, but nothing helped. Here is my XML (the element is root): <?xml version="1.0" encoding="utf-8"?> <mathtex>\int_0^\pi {sin x\over x} > 0</mathtex> And here is my ConTeXt environment file (I am using version 2010.05.24 13:05): \startxmlsetups doc:mathtex $\xmlflush{#1}$ \stopxmlsetups \xmlregistersetup{xml:doc} \startxmlsetups xml:doc \xmlsetsetup{\xmldocument}{mathtex}{doc:*} \stopxmlsetups Any hint?
