TeX "matrix" command not working lately
by L.S.-Soc&Gam 10 Apr '16

10 Apr '16

Hi guys, i've already searched the mailing list for this but i still am having a problem while trying to create a matrix. my code looks like this: \startformula S=\left(*\matrix**{* \sigma_x *&* \tau_{xy} *&* \tau_{xz} *\cr* \tau_{yx} *&* \sigma_y *&* \tau_{yz} *\cr* \tau_{zx} *&* \tau_{zy} *&* \sigma_z *\cr* *}*\right)_{xyz} \stopformula But since a few days, there are only empty braces after compilation. The funny thing is, i worked already. but i've updated context at least once since (only 5 days ago, betas included) and since then after compiling there are only empty braces. When i enter \startformula S=\left( 1234 \right)_{xyz} \stopformula the 1234 shows fine between the braces. so it seems to have to do with \matrix command in some way... i don't know any alternative way to create a matrix. any help would be appreciated. Greetings, Sebastian

wrong beta version number?
by Pablo Rodriguez 10 Apr '16

10 Apr '16

Hans, I have just updated the latest version from the ConTeXt Suite and it contains: \edef\contextversion{2016.04.01 13:01} Is the version number wrong or does the Linux 32bit distribution have a previous version? Many thanks for your help, Pablo -- http://www.ousia.tk

defining a comamnd as variable which behaves as constant
by Pablo Rodriguez 10 Apr '16

10 Apr '16

Dear list, I have the following document: \mainlanguage[es] \starttext \startTEXpage[offset=1em] \dorecurse{27}% {\def\abcd{\convertnumber{a}{\recurselevel}}% \dorecurse{27}% {\abcd\convertnumber{a}{\recurselevel} }\par} \stopTEXpage \stoptext I want to test all lowercase-letter pairs in Spanish. Excuse me for my missing programming notions. For the sample above, I would need a command that behaves as a variable when defined, but as a constant when invoked. Is there any way to achieve that without using counters? Sorry if there is too much nonsense in the previous paragraph. But I need to know how to do it for another example too. Many thanks for your help, Pablo -- http://www.ousia.tk

Weird background colors in autogenerated index
by Jan Tosovsky 09 Apr '16

09 Apr '16

Dear All, since LuaTeXt 0.81 my back-of-the-book index (register) is generated with strange background colors. The index title is typeset in yellowish background and the left column of the last index page has a blue background, see the attachment. I've thought I reported it, but it is still there even in 0.95. It was fine in the version 0.80. Could this be somehow eliminated? Thanks, Jan

Ligature color is not reliable
by Jan Tosovsky 09 Apr '16

09 Apr '16

Dear All, for an illustration I wanted to colorize all ligatures, but the following method is not reliable for three character ligatures - which ends up black. While tested with Palatino, it can be simulated even with a default font (however there are missing ffi and ffl ligatures). \definefontfamily[palatino][rm][Palatino Linotype][features={default, quality}] \setupbodyfont[palatino] \starttext Je{\red ff}, the o{\red ffi}ce on the {\red fi}rst {\red fl}oor is o{\red ffl}ine. \stoptext What is happening here? Thanks, Jan

Increasing the textwidth locally
by joasyannick＠gmail.com 09 Apr '16

09 Apr '16

Dear everyone, I am looking for a functionality similar to the \adjustwidth command in LaTeX ables to reduce or increase the \textwidth locally. I know that ConTeXt has \startnarrower, which reduces the \textwidth. But how to increase it? All the best, Joas

unwanted head behavior
by Zhichu Chen 09 Apr '16

09 Apr '16

Dear Hans and Wolfgang, The following code generates a pdf that I cannot understand. 1. Although "placehead" is set to "no," the \part macro still makes an empty line. 2. The first \chapter does not open a new page, but if we switch the first \title and the first \chapter, the result seems to be all right. Is there a simple fix? Thanks in advance. ================================== \setuphead [part,chapter,title,section] [continue=yes,page=yes,number=no] \setuphead[part][placehead=no] \showframe \starttext \input ward\page \part{TITLE}\input ward\par \title{Title} \chapter{Title} \chapter{Title} \title{Title} \chapter{Title} \stoptext ================================== ConTeXt minimal information: zhichu  ~  context -version mtx-context | ConTeXt Process Management 0.63 mtx-context | mtx-context | main context file: /opt/context/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2016.03.26 13:51 zhichu  ~  luatex -version This is LuaTeX, Version beta-0.90.0 (TeX Live 2016) Execute 'luatex --credits' for credits and version details.
