typesetting content of attribute
by Meer, Hans van der 30 Apr '16

30 Apr '16

The aim is to typeset a TeX-command given in an attribute on an xml node. Example ... \xmlatt{#1}{style} ... where the node has <node style="\bf"/> The problem is that this produces the macrotext \bf and does not execute the \bf. I guess that the catcoderegime is not that of TeX here. With what (magical) incantation to do this? Nb. I know that here I could have coded 'bf" and called with \csname..\endcsname, but this is but a simple example and would not work for '\it\bf', etc. Hans van der Meer

evaluation of != and ~=
by Meer, Hans van der 29 Apr '16

29 Apr '16

This one took the better part of an afternoon from me, but I finally found the (unexpected) culprit. In the xml documentation on page 31 it is said: The given expression between [] is converted to a LUA expression so you can use the use operators: == ~= <= >= < > not and or () In addition, = equals == and != is the same as ~=. This is not true as the following demonstrates. The use of != is as expected but the ~= leads to an error and this should not be: xml> lpath > error in expression: number(@atta) ~= 1 => expr.number((ll.at<http://ll.at> and ll.at<http://ll.at>['atta'])) ~== 1 Hans van der Meer % failure of test on inequality. \startxmlsetups demo:comparefail \xmlsetsetup{#1}{root|node}{demo:comparefail:*} \stopxmlsetups \xmlregisterdocumentsetup{demo}{demo:comparefail} \startxmlsetups demo:comparefail:root compare \type{!=}\crlf \xmlfilter{#1}{/[number(@atta) != 1]/command(demo:comparefail:node)} compare \type{~=}\crlf \xmlfilter{#1}{/[number(@atta) ~= 1]/command(demo:comparefail:node)} \stopxmlsetups \startxmlsetups demo:comparefail:node node: attribute atta = \xmlatt{#1}{atta}\crlf \stopxmlsetups \startbuffer[comparefail] <root> <node atta="2"/> <node atta="1"/> </root> \stopbuffer \starttext \xmlprocessbuffer{demo}{comparefail}{} Note the absence of output in the second \tex{xmlfilter}. \stoptext

Fonts inside eqno{}
by Freddy Omar López Quintero 29 Apr '16

29 Apr '16

Hello all! I'm interested in change the natural numbering of one equation with \eqno{} but it does not follow the main font selected. A minimal example: %%%%%%%%%%%%%%%%%%%%%% \usemodule[simplefonts] \setmainfont[Linux Biolinum O] \setmathfont[Linux Biolinum O] \starttext I have the following expression \placeformula \startformula y = Z \beta_1 + Y \beta_2 + u \stopformula that changes to % \placeformula \startformula y = Z \beta_1 + Y \beta_2 + W_1\tau + u \eqno{ (1')} \stopformula \stoptext %%%%%%%%%%%%%%%%%%%%%% I would like the (1') keep the same kind of font than (1). Any hint will be appreciated. Thanks! -- «...my role is to be on the bottom of things.» Donald Knuth

’Undefined control sequence’ with basic example
by Saša Janiška 29 Apr '16

29 Apr '16

Hello, I had to prepare some text for my mother by extracting some portions from her book (done in LyX/LaTeX) and now wanted to use it as example to see the quality of job done by LuaTeX… However, converting LyX —> LaTeX —> Pandoc –> ConTeXt failed and I tried with the simple example (http://wiki.contextgarden.net/Command/startsection) % mode=mkiv \setuppapersize[A5] \starttext \startsection[ reference=sec:One, title={Section One}, ] For a subsection, see \in{subsection}[sec:Two:Sec]. \stopsection \startsection[ reference=sec:Two, title={Section Two}, ] [a_variable={some value}] a_variable=\quote{\structureuservariable{a_variable}}. \startsubsection[ reference=sec:Two:Sec, title={Here’s a subsection}, ] In this subsection there’s some text\ldots \stopsubsection \stopsection \stoptext but running it under Debian (Sid) gives: [gour@atmarama ~/prj/knjiga]$ luatex t.tex This is LuaTeX, Version beta-0.80.0 (TeX Live 2015/Debian) (rev 5238) restricted \write18 enabled.

right to left direction for itemize columns
by Bou Salim 28 Apr '16

28 Apr '16

I have posted a question in tex stack exchangeCustomize right to left list in context <http://tex.stackexchange.com/questions/294627/customize-right-to-left-list-…> My aim is to obtain right to left items arranged in multi-column, if I use \startitemize [s,columns,three] [margin=1em] the result is three column where first column start from left side of page, but I want it to start from right side of page. I can use \startcolumns[direction=left]\startitemize \item First \item Second \item Third \stopitemize \stopcolumns but I think it look better if there is a key direction=left for the \startitemize environment such as used in columns environment.

Server is up again
by Mojca Miklavec 27 Apr '16

27 Apr '16

Dear ConTeXters, I'm sorry that it took so long, but the server should be up again (with everything but gitlab restored to the previous state). Both hard drives in the machine died simultaneously on the 3rd of April without any previous signs of malfunctioning. The administrator got a new machine with new hard drives up and running a few days ago. If you experience any problems with the distribution, meeting page or alike from this point on, let me know.

Updating ConTeXt standalone problem on Mac OS X
by Jaroslav Hajtmar 26 Apr '16

26 Apr '16

Hello ConTeXist I have a problem with updating ConTeXt on my Mac OS X (El Captain). When you run the update script to me an error message appears, which surprises me, since I logged on as the system administrator. Can anyone advise me on what could be the problem. I note that I am a beginner on OS X. Here is problematic report: Jaroslav-MacBook-Air:context hajtmar$ sh first-setup.sh receiving file list ... done rsync: failed to set times on "/Users/hajtmar/context/bin": Operation not permitted (1) bin/ rsync: mkstemp "/Users/hajtmar/context/bin/.luatex.y7B2Zy" failed: Permission denied (13) etc.... Thanx Jaroslav Hajtmar

useMPgraphic scaling
by Meer, Hans van der 26 Apr '16

26 Apr '16

With images one can scale them on placement, for example \externalfigure[][scale=250,height=..] etc. Is such a scaling or separate height,width setting also possible with the placement of useMPgraphic? Or needs all scaling of thesebe done within the metapost/metafun code? Hans van der Meer
