[***SPAM***] unwanted space and error in combination of writebetweenlist and placecontent[criterium= local]
by Zenlima 13 May '13

13 May '13

Hi, I ran into one error and one problem during building a part as two columns into the toc. 1. Extra line: I am getting an unwanted extra empty line at the bottom of two columns with an even number of total lines - with an odd number of total lines no extra empty line appears. How can I get rid of it? (see attached example) 2. This error only appears only with \placecontent[criterium=local] in combination with a beginning line of \writebetweenlist; with a global \placecontent and \writebetweenlist it works fine. To reproduce this uncomment the line "%\placecontent[criterium=local]" in the attached example. (Sorry that I was not able to make the example shorter, I needed some "meat" to fill the toc for the showcases) Thanks, H. --8<---------------------------- \usemodule[subsub] \definehead[paragraphHead][alternative=myheader,section=section-8,number=no] \defineheadalternative [myheader] [alternative=horizontal, renderingsetup=setup:myheader] \startsetups [setup:myheader] \inouter{\headtextcontent} \stopsetups \setuplist[chapter][style=bold,before=\blank,alternative=b,width=1.5em,color=HeadColor] \setuplist[section][margin=1.5em,width=2em] \setuplist[subsection][margin=3.5em,width=3em] \setuplist[paragraphHead][alternative=c,style=\tfx] \def\startParagraphTocColumns{% \writebetweenlist[paragraphHead][location=here]{\setupnarrower[left=2em]\startnarrower[left]\startcolumns[n=2,distance=0mm,balance=yes]}% \ignorespaces} \def\stopParagraphTocColumns{% \writebetweenlist[paragraphHead][location=here]{\stopcolumns\stopnarrower}% \ignorespaces} \starttext \setupcombinedlist[content][list={chapter,section,subsection,textdividerHead,paragraphHead}] \completecontent \startParagraphTocColumns \dorecurse{5}{\paragraphHead{Hasselt makes headlines} \input tufte} \stopParagraphTocColumns \chapter{Lorem ipsum} \section{Sed eram} \chapter{Lorem ipsum} %\placecontent[criterium=local] \section{Sed eram} \section{Sed eram} \startParagraphTocColumns \dorecurse{5}{\paragraphHead{Hasselt makes headlines} \input tufte} \stopParagraphTocColumns \section{Sed eram} \section{Sed eram} \startParagraphTocColumns \dorecurse{4}{\paragraphHead{Hasselt makes headlines} \input tufte} \stopParagraphTocColumns \section{Sed eram} \startParagraphTocColumns \dorecurse{3}{\paragraphHead{Hasselt makes headlines} \input tufte} \stopParagraphTocColumns \section{Sed eram} \section{Sed eram} \stoptext

[luatex-fonts] +mkmk; +mark results in call to undefined onetimemessage()
by Philipp Gesang 12 May '13

12 May '13

Hi, in luatex-plain, the example below \font\grk="file:LinLibertine_R.otf:+mark;+mkmk;mode=node" at 14.4pt {\grk μῆνιν ἄειδε θεὰ Πηληϊάδεω Ἀχιλῆος\hfill\break οὐλομένην, ἣ μυρί' Ἀχαιοῖς ἄλγε' ἔθηκε} \bye triggers a call to onetimemessage() which is nil at the time when the upvalue is created. Can we have calls to fonts.loggers.onetimemessage() instead, so we can override that one with our own logger? On a related note, we would like to reduce verbosity. In luatex-basics-gen.lua, could we have: logs = logs or { new=dummyreporter, reporter=dummyreporter, messenger=dummyreporter, report=dummyfunction, } So we can provide our own “logs” table? Thanks Philipp

python parse/formatter example on the wiki
by seasoul 11 May '13

11 May '13

I was trying the example of "writing a parse/formatter" under "Verbatim text". The python formatter runs successfully. But when I compile the text file with all the definitions included, an error occurs. <inserted text> } <to be read again> \endgroup \buff_verbatim_type_block_verbatim_indeed ...ines \dostoptagged \csname #2\e... It could be implemented forcefully, but definitely not an excuse to ignore this error. Any solutions?

Formulas in ConTeXt are different from those in plain TeX
by Tim Li 11 May '13

11 May '13

Hi, I have asked this question on tex.stackexchange.com http://tex.stackexchange.com/questions/113592/formulas-in-context-are-diffe… as the title said, formulas typeset by ConTeXt are different from those by plain TeX. The minimal examples are here: % plain luatex in ConTeXt standalone $$\int_a^bf(x)dx=F(b)-F(a)$$ \bye % context \starttext \startformula \int\nolimits_a^bf(x)dx=F(b)-F(a) \stopformula \stoptext Marco said to me that that's because the fonts used by LuaTeX and ConTeXt are different. This can be seen from the pdf produced by them pdffonts context.pdf name type emb sub uni object ID ------------------------------------ ----------------- --- --- --- ---------OLAZTU+LMRoman12-Regular CID Type 0C yes yes yes 18 0 RXHAAY+LatinModernMath-Regular CID Type 0C yes yes yes 19 0JTHTZJ+LatinModernMath-Regular CID Type 0C yes yes yes 20 0 pdffonts plain.pdf name type emb sub uni object ID------------------------------------ ----------------- --- --- --- --------- APMHZE+LMMathExtension10-Regular Type 1 yes yes no 4 0 AWBTPY+LMMathItalic7-Regular Type 1 yes yes no 5 0 ITITNI+LMMathItalic10-Regular Type 1 yes yes no 6 0 DMNVHT+LMRoman10-Regular Type 1 yes yes no 7 0 MGKPYK+LMMathSymbols10-Regular Type 1 yes yes no 8 0 even if using the `modern-designsize-virtual` typescript(advice from Marco), I still get the different outputs. Now, I get confused about this qustion. If ConTeXt uses LuaTeX as its engine, how can I tune ConTeXt so that it can produce the same formulas with those in plain TeX? Tim

[luatex-fonts] font cache behavior

10 May '13

Hi all, this document: \font\foo="file:LinLibertine_R.otf:+onum;mode=node;" \foo foo 12345 whatever \bye works correctly if the font is uncached but leads to garbled output in firefox’s pdf plugin if the font is loaded from cache. Afaics none of the other viewers are affected. Also I haven’t found another font that does this. Libertine fonts: http://sourceforge.net/projects/linuxlibertine/files/linuxlibertine/5.3.0/ (First observed by Luigi.) What is going on here? Philipp

font-age vs. font-agl
by Philipp Gesang 10 May '13

10 May '13

Hi all, the glyph list is a bit of a conundrum. Context (font-enc.lua) will build its glyph list from font-agl.lua and char-def.lua. Luatex-Fonts reads a file named font-age.lua, which is, however, some 500 character definitions short of the canonical Glyph List from Adobe’s resources [1]. On the other hand, font-age contains these definitions table={ ["SF10000"]=9484, ["SF20000"]=9492, ["SF30000"]=9488, ["SF40000"]=9496, ["SF50000"]=9532, ["SF60000"]=9516, ["SF70000"]=9524, ["SF80000"]=9500, ["SF90000"]=9508, ["afii208"]=8213, } which Adobe denotes padded as SF010000;250C SF020000;2514 SF030000;2510 SF040000;2518 SF050000;253C SF060000;252C SF070000;2534 SF080000;251C SF090000;2524 afii00208;2015 I’m not sure what to make of these differences and how they came to pass except for some older posts in the list archive [2]. So I’m asking for practical reasons: Are the differences of any significance? Can I use either list or should I stick with font-age? Thanks for any advice Philipp [1] http://partners.adobe.com/public/developer/en/opentype/glyphlist.txt [2] http://www.ntg.nl/pipermail/ntg-context/2008/031575.html http://www.ntg.nl/pipermail/ntg-context/2008/029067.html

Set layout for the first page of Chapters
by Tim Li 10 May '13

10 May '13

Hi, when designing some documents, I hope I can set a global layout and another layout for the first page of all chapters. I have defined two layouts as follows: \setuppagenumbering [alternative=doublesided, location=] % global layout for the whole document \setuplayout [backspace=2.5cm, width=16.5cm, topspace=2cm, height=25.2cm, header=\lineheight, headerdistance=\lineheight, footer=0cm] % layout for the first page of Chapters \definelayout [firstpage] [height=26.2cm, footerdistance=\lineheight, footer=\lineheight] \starttext \chapter{First Chapter} I am in the first page. \page I am in the second page. \stoptext my question is that how I can apply this `firstpage' layout to the first page of the chapter `First Chapter' and switch back to the global layout after the first page of this chapter? Best Regards,Tim

Obtaining the current font
by Marco Patzer 10 May '13

10 May '13

Hi, in the gnuplot module the following macro is used for the TikZ terminal: \def\calculateGNUPLOTcharsize{% \global\GNUPLOThcharsize=1.05\fontcharwd\font`0% \global\GNUPLOTvcharsize=1.05\fontcharht\font`0% \global\advance\GNUPLOTvcharsize by 1.05\fontchardp\font`g% } What are \font`0 and font`g? AFAIK the backtick converts the character to the character code, which means it yields \font48 and \font103. The goal is to get the current font, right? Why is the current font width and height addressed with `0 and the depth with `g? And when do `0 and `g result in different values? In my tests they were always the same. Marco

mpgraphics confusion

I am a bit confused about the metafum graphis.

I fail to see in what respect startuseMPgraphic en startuniqueMPgraphic do differ? Can someone please explain? Hans van der Meer

LuaJitTeX, \texenginename, and \texengineversion
by Kip Warner 09 May '13

09 May '13

Hey Luigi, I find the \texenginename and \texengineversion useful for retrieving the backend name and version. They work fine when using the vanilla LuaTeX backend. However, when using LuaJitTeX, the aforementioned macros still seem to retrieve LuaTeX specific information and not LuaJitTeX - unless I'm doing something wrong. I was careful to ensure I passed --engine=luajittex to context as well. -- Kip Warner -- Software Engineer OpenPGP encrypted/signed mail preferred http://www.thevertigo.com

Specially with a final "nuun" there are problems. It is not a problem of the font, because in Word they are set correctly.

Or asked more generally, if fixing is not possible: Do you know any font, which can correct handled by context, and is capable of typesetting quran? Thanks. Huseyin

Installing an arabic font
by "H. Özoguz" 08 May '13

Hoping to annoy not everybody here with my arabic-font-questions. I have found I nice free arabic ttf-font, you can download it here: http://fonts.qurancomplex.gov.sa/wp-content/uploads/2012/06/UthmanTN1-Ver10…. One of its types is: "kfgqpcuthmantahanaskhregular" If I type in the cmd C:\Users\Hussein>mtxrun --script font --list --all --pattern=*kf* I get (together with some other lines/fonts): kfgqpcuthmantahanaskhregular kfgqpcuthmantahanaskh c:/windows/fonts/UthmanTN1 Ver10.otf So everything should be ok. But now the following failes: \definefont[amiri][name:kfgqpcuthmantahanaskhregular*arabic at 17 pt] \define[1]\Arab{\setupalign[r2l]\amiri#1} \starttext \Arab{ بِسْمِ ‏للهِ الرَّحْمَـٰنِ الرَّحِيمِ } \stoptext It compiles, but the output is destroyed, the letters have distances between them. See attached pdf. (In other programms, e.g. MS Word that does not happen, and the font is set correctly.) Apart from this mistake, the font is perfect set by context, even the "Allah" and its "Kassra" has a nice distance (see the other thread). Indeed, if this distace-between-letters problem could be solved, I am happy with arabic in context, this font would be enough, and all other threads of mine could be closed (as far as I am concerned :)) Thanks for your help!

TEXpage filename
by Alan BRASLAU 08 May '13

08 May '13

Hello, In the production of (scientific) articles for journal submissions, one is often expected to supply the figures as separate files. One workflow can be through the use of \startTEXpage\stopTEXpage followed by an external extraction of single pdf pages to separate files. However, is it possible or would it be possible to directly output to a named file, as in: \startTEXpage{figure1.pdf} \stopTEXpage or perhaps \startTEXpage [file=figure1.pdf] \stopTEXpage ? (I could not find an answer looking at the source.) One could then (optionally) reinclude the figure in a review copy of the full text through the use of \externalfigure [figure1] Alan

Small bug in the result filename extension in log

Hi, I just noticed a small bug in the log of a context job. It has no incidence but maybe this can cause a side effect somewhere. When a file contain several dot in its name, context remove the last part in the result filename in the log: $ context test.foo.bar ... system > files > jobname 'test.foo.bar', input './test.foo.bar', result 'test.foo' ... However, the output is correct and one obtain 'test.foo.bar.pdf' and not 'test.foo.pdf'. All the best. -- Romain Diss <romain.diss(a)yahoo.fr>
