To update or not to update - that is the question...
by Marcin Borkowski 18 Mar '13

18 Mar '13

Hi all, I have an issue with \overrightarrow being positioned under its argument. I've read on the list that this is now fixed, but... I can't upgrade! This is because I'm preparing a document in an "incremental" way, that is, I'm preparing course materials (problem sets) for the next class each week and giving them away to students. If I upgrade, the pagebreaks change (probably due to some tweaking Hans added to multicolumn itemgroups a few months ago). So what would you suggest? I can see at least three solutions, none of which is ideal for me. 1. Manually backport the fix to my ConTeXt. Pro: ideal solution (at least for now). Con: no idea how to do it - I don't know how to access ConTeXt repository (if it's at all possible for a non-developer). 2. Upgrade and insert some manual pagebreaks so that pages 21-22 (which I'm currently working on) contain the same problems as they used to. Pro: easy fix. Con: very dirty trick, and what if someone asks me about some old problems, because he lost his copy? 3. Just use \vec instead of \overrightarrow. Pro: very easy, no dirty hacks. Con: ugly looking (see: \vec{AB}). Any ideas? Is it possible to find the official ConTeXt repo somewhere, or if not, maybe someone could send me the diff of the commit which fixed that (this post: http://article.gmane.org/gmane.comp.tex.context/79011 suggests that it is the 2012.10.30 21:13 commit)?

How to fix a break
by hwitloc＠gmail.com 17 Mar '13

17 Mar '13

I'm getting "mtxrun | unknown script 'context.lua' or 'mtx-context.lua'" on the three line \starttext This is the text section. \stoptext This is the TeXLive distributed version and it worked yesterday. I'm pretty sure I messup up the paths or tex path database used by kpathse, etc. Is there a program I can run to go through a texlive installation and rebuild the TDS database? Thanks

TeX macro to MP variable
by Marco Patzer 17 Mar '13

17 Mar '13

Hi, I am looking for a way to assign the value of a TeX macro to an MP variable. However, this only works the first time, then the value is not updated any longer. Example: \startMPdefinitions size = \somesize ; \stopMPdefinitions \startuseMPgraphic{alpha} fill unitcircle scaled size; \stopuseMPgraphic \starttext \def\somesize{1cm} \useMPgraphic{alpha} %% diameter = 1cm \def\somesize{2cm} \useMPgraphic{alpha} %% diameter = 1cm \stoptext I looked into \setupMPvariables, but I couldn't manage to assign them to an MP variable. The setups key from \defineMPinstance seems to to the job, but it's TeX, not MetaPost. What comes to mind is a \processMPbuffer before every MPgraphic: \startbuffer[foo] size := \somesize ; \stopbuffer \startuseMPgraphic{alpha} fill unitcircle scaled size; \stopuseMPgraphic \starttext \def\somesize{1cm} \processMPbuffer[foo] \useMPgraphic{alpha} %% diameter = 1cm \def\somesize{2cm} \processMPbuffer[foo] \useMPgraphic{alpha} %% diameter = 2cm \stoptext Is there a better way?

\feature
by Hans Hagen 17 Mar '13

17 Mar '13

Hi, After some experimenting, I settled on the next interface for dynamic features: The is also a generic command \type {\feature} that takes two arguments. Below we show all calls, with long and short variants: \starttyping \addfeature [f:mine] \feature [more][f:mine] \feature[+][f:mine] \subtractfeature [f:mine] \feature [less][f:mine] \feature[-][f:mine] \replacefeature [f:mine] \feature [new][f:mine] \feature[=][f:mine] \resetandaddfeature[f:mine] \feature[local][f:mine] \feature[!][f:mine] \revivefeature [f:mine] \feature [old][f:mine] \feature[>][f:mine] \resetfeature \feature[reset] \feature[<] \stoptyping Each variant also accepts \type {{}} instead of \type {[]} so that they can conveniently be used in square bracket arguments. This mechanism replaces \addff cum suis, although for a while they will stay around (mapped onto add and subtract). Idris is testing it (as he used this kind of trickery extensively for complex arabic) and he make a nice wiki page. We can think of a predefined set of simple features.

noalign hassles
by H. van der Meer 17 Mar '13

17 Mar '13

I am stuck with the following problem. Inside an \halign (table) I can insert a colored rule with: \noalign{\color[red]{\hrule height#1 depth\zeropoint}} Now I want something more involved like: \color[red]{\hrule height#1 width2mm}% fixed length colored block \color[black]{\hrule height#1}% filling the width left \color[red]{\hrule height#1 width2mm}% fixed length colored block producing [red][black black black …][red] However, this doesn't work. I tried various options as: enclosing in \vbox, \hbox, box with leaders. Nothing worked out. Is there some guru who knows how to accomplish this? Hans van der Meer

switching language introduces spurious space

Hi Hans, there is a small typo in l. 390 of lang-ini.mkiv which introduces a spurious space when you switch language: --- lang-ini.mkiv 2013-03-16 18:06:05.547177226 +0100 +++ lang-ini.mkiv.new 2013-03-16 18:07:04.443844765 +0100 @@ -387,7 +387,7 @@ \let\dohyphens\relax \unexpanded\def\lang_basics_synchronize_min_max - { % these values are stored along with glyph nodes + {% these values are stored along with glyph nodes \lefthyphenmin \numexpr0\languageparameter\s!lefthyphenmin +\hyphenminoffset\relax \righthyphenmin\numexpr0\languageparameter\s!righthyphenmin+\hyphenminoffset\relax % these values are stored with the language (global!)

narrower and whitespace
by H. van der Meer 16 Mar '13

16 Mar '13

I find that in intro text \startnarrower narrow text \stopnarrower after text blank vertical space is inserted both before and after the narrower block. How can I avoid that? Hans van der Meer
