temporarily disabling enumeration numbering
by Vianney le Clément 05 Apr '10

05 Apr '10

Hello again, Section 10.3 of the manual says that one can disable numbering for one item of an enumeration by putting [-]. However, this seems to affect the following item instead of the current one. For example, \defineenumeration[MyEnum][location=left] \starttext \MyEnum First\par \MyEnum[-] Second\par \MyEnum Third\par \MyEnum Fourth\par \stoptext removes the number of the third line, instead of the second one.

\framed[location=top] and slanted tex gyre bonum
by Vianney le Clément 05 Apr '10

05 Apr '10

Hello, Yet another new ConTeXt user here. To briefly introduce myself, I am a computer scientist interested in typography as a hobby. Up to now, I did most things in LaTeX (sometimes resorting to ugly TeX hacking). Recently I gave ConTeXt MkIV a try and am quite happy with it. Now my question: I have some problems with the vertical alignment of \framed and some slanted fonts. Using the latest beta, the test file at the end of this message adds a slight whitespace in the two last blocks (using a slanted font). This does not happen when using the default Latin Modern font. Is this a bug or am I doing something wrong?

Splitting a page in given ratios
by Matthias Weber 05 Apr '10

05 Apr '10

Dear all, this is probably even easy in plain TeX, but as I have never learned it properly, I am asking anyway: I would like to have a way to split a part of a page into two columns of different width, so something like \startsplitpage[columns=2,spacing=fill] \startcolumn[1][width=.6 \textwidth] \input{tufte} \stopcolumn[1] \startcolumn[2][width=.3 \textwidth] \placefigure[theBeerBottle] \stopcolumn[2] \stopsplitpage so that the individual columns are treated (if possible) as separate pages with all features (like \framed etc) adapted to the page width of the smaller sub-pages. This could replace (for me) the somehow (for me) disfunctional figuretext construct. Is there a way to do this? Thanks, Matthias

Need help with the "letter" module
by Matija Šuklje 05 Apr '10

05 Apr '10

Hullo, I'm trying to write a letter, but it gets all screwy. The first batch of letter settings works OK (opening, closing, signature); but then the from* and to* blocks fail resulting in a PDF that just quotes that code on a separate page. Clearly I'm doing something wrong although I'm looking at the manuals: http://dl.contextgarden.net/modules/t- letter/doc/context/third/letter/correspondence.pdf MkII from TexLive 2008. Any help welcome :] --[snip]-- \mainlanguage[en] \enableregime[utf8] \setuppapersize[a4][a4] \usemodule[letter] \setupletter [opening={Dear FSFE,}, closing={Best regards,}, signature={Matija Šuklje\\Coordinator FSFE Fellowship group Slovenia}] [fromname={Matija Šuklje}, fromaddress={Dvořakova 10\\SI-1000 Ljubljana\\Slovenia}] [toname={Free Software Foundation Europe e.V.}, toaddress={Talstraße 110\\D-40217 Düsseldorf\\Germany}] \starttext \startletter \input knuth \stopletter \stoptext --[snap]-- -- gsm: +386 41 849 552 www: http://matija.suklje.name xmpp: matija.suklje(a)gabbler.org

caption on the inner side
by Hubertus 05 Apr '10

05 Apr '10

Hello all, I was wondering if it possible to do something of this sort: \setupcaptions[location=low] \placefigure[outer][]{ Caption } {\externalfigure[test.jpg][width=0.5\textwidth]} So what I try is to get the caption not on the left side of the image but "inner". From the location pramametar there seems not to be an obvious solution, neither in the mail archive. Cheers, Hubertus

using xmlsetups
by Hans van der Meer 05 Apr '10

05 Apr '10

I cannot get multiple separate \xmlsetsetup's working. Obviously I am doing something wrong. My idea was: file included contains: \startxmlsetups xml:commoncontext:commonsetups \xmlsetsetup{}{error|tex|html|nbsp|...|br}{xml:commoncontext:*} \stopxmlsetups \xmlregistersetup{xml:commoncontext:commonsetups} \startxmlsetups xml:commoncontext:br \crlf \writestatus{CALLING}{br} % <<< apparently not called! \stopxmlsetups \startxmlsetups xml:commoncontext:b {\bf\xmlflush{#1}} \stopxmlsetups ...... file that includes contains: \startxmlsetups xml:doccase:doccasesetups \xmlsetsetup{}{*}{xml:commoncontext:*} % {doc}{*}..also does not work \xmlsetsetup{doc}{*}{xml:case:*} % does work for setup 'xml:case' \xmlsetsetup{doc}{error|dvd|titles...|source|stars}{xml:doccase:*} \stopxmlsetups \xmlregistersetup{xml:doccase:dvoccasesetups} \startxmlsetups xml:case:text \xmlflush{#1} \stopxmlsetups .... etc. Usage: <doc><text>The break not called<br/> and similarly <b>not called</ b><text></doc> Where is the flaw here?

missing \xmlflushsetups?
by Hans van der Meer 05 Apr '10

05 Apr '10

I thought one can register various setups and then when setting up the processing of the root tag call them into being with: \xmlregisteredsetups (according to the docs "applies all global setups to the current document) But doing this as in: \startxmlsetups xml:doc:roottag xmlregisteredsetups ... I get instead the error: ! Undefined control sequence. \xmlregisteredsetups ...arttiming \xmlflushsetups \xmldefaulttotext \xmldocu... \@@su:xml:dvdcase:dvd #1->\xmlregisteredsetups Hans van der Meer

Hans' presentation: using plain TEX (from TUG 2009) [apologies if OT]
by Graham Douglas 04 Apr '10

04 Apr '10

Dear Hans, Taco et al I hope this is the appropriate place to ask my question --- if not, my apologies. I've compiled LuaTeX on Windows and have been using Hans' presentation "using plain TEX" (from TUG 2009) to construct a minimal working runtime environment based on plain tex. Basically, a hand-coded texmf.cnf and a minimal (non-ConTeXt) environment/TDS constructed around the "build" directory created by build.sh. The reason for doing this is to start with a setup which is the minimum possible, as a way to learn. ConTeXt is very powerful and orders of magnitude more complex than plain (obviously...) so I needed to strip that away, for now. It seems to work well, so far. My question relates to fonts. In the luatex-plain example: \input plain \directlua {tex.enableprimitives('', tex.extraprimitives())} \pdfoutput=1 \everyjob \expandafter {% \the\everyjob \input luatex-basics\relax \input luatex-fonts\relax \input luatex-mplib\relax } \edef\fmtversion{\fmtversion+luatex} ===> luatex --ini luatex-plain.tex You include some ConTeXt font machinery which I'd like to experiment with using fonts I have in .afm/.pfb format only. I ran mtxrun --script font --names to generate a font name database (luatex-fonts-names.lua) ["mappings"]={ ["aharonibold"]={ "Aharoni Bold", "C:/Windows/fonts/ahronbd.ttf" }, ["andalus"]={ "Andalus", "C:/Windows/fonts/andlso.ttf" }, ["angsananew"]={ "Angsana New", "C:/Windows/fonts/angsa.ttf" }, ["angsananewbold"]={ "Angsana New Bold", "C:/Windows/fonts/angsab.ttf" <<snip lots>> and copied it across to my plain tex texmf tree. Works fine, PDF outputs perfectly, so it enables lots more fonts in the plain format. However, the database is clearly restricted to TrueType and OpenType fonts so my question is: Does the font machinery included by: \input luatex-basics\relax \input luatex-fonts\relax \input luatex-mplib\relax provide support for afm/pfb fonts? TrueType etc are OK like this: \font\testf=[arialbolditalicmt] at 12pt (name taken from database) However, as soon as I try to use this with afm/pfb files it fails, unable to find the metrics. For example: \font\testa=file:MinionRegularItalic_wt350_wd450_op10 at 34pt It may be potentially bad names that I'm using with underscores (they are all named like this Minion_wtX_wdY_opZ) (X,Y,Z are values for weight, width and optical size) But it also failed with simple font names. I checked that the fonts can be found: \directlua { local found = kpse.find_file("MinionRegularItalic_wt350_wd450_op10","afm") tex.print("$$"..found.."$$") local ifound = kpse.find_file("MinionRegularItalic_wt350_wd450_op10","type1 fonts") tex.print("$$"..ifound.."$$") } ($$ is a silly hack due to the _) So, is it possible to find and load .afm/.pfb with your luatex-plain example. Is that font machinery included in luatex-plain? If so, can you suggest why the luatex-plain example might be failing with the .afm/.pfb files? I would be very grateful for any insights you can provide. Many, many thanks in advance. And another busy day on the list!!! Warm wishes Graham

Shaped paragraphs
by Erik Margraf 04 Apr '10

04 Apr '10

Hi, I have some problems using shaped paragraphs. I tried to follow the procedures described in METAFUN in the chapter about "talking to TeX". The output I get from running context (latest minimals) is wrong (or at least unexpected ;-). The shape of the text paragraphs doesn't match the backgrounds. They are interchanged. If I comment out any single shape production it works. My Example (hope, it's near to minimal) is attached kind regards Erik
