winter cleanup in the wiki
by Jonas Stein 14 Dec '10

14 Dec '10

Hi, there are (were) many duplicate installation pages in the wiki. I merged some and deleted a lot duplicate stuff. The work is not finished yet. i created a new category in the wiki: http://wiki.contextgarden.net/Category:deleteme These articles are merged to others and no longer needed. Is the part about Configuration files still up to date? http://wiki.contextgarden.net/Installation_hints Its last edited in 2008 and links to manuals from 2001 and 2003. Kind regards, -- Jonas Stein <news(a)jonasstein.de>

How about a forum
by Achim Jander 13 Dec '10

13 Dec '10

Hi everybody, I am trying to get into Context again. The documentation seems to be somewhat better than one year ago (my last attempt) but still very suboptimal. Many information (as well on Contextgarden as on Pragma) is outdated, for example, the xml document on Pragma is dated 2001, the "first document" on the context wiki does not mention mkiv (ok, at least now there is a hint that something should be done about that). For a newbie like me, the best chance of information seems to be the mailing-list, where one can find a lot of gems. After spending this cold and snowy sunday afternoon with the mailing-list (and i got no further than to september 2010) I am wondering why there ist no forum for Context. I spend a lot of time getting into new themes, and I always like the functions of forums. I think in a forum the acces to the relavant information could be very quicklier than in a Mailing-List - which is in my opinion a relict of the information possibilities of the 1990 (last century, only a minute away from the middle ages :-). Dont get me wrong, I like the unbelievable support which is done on the mailing-list, but i think today there could be more efficient possibilities. Any suggestions on that? Thanks, Achim

xml: test for attribute
by Thomas Schmitz 13 Dec '10

13 Dec '10

Hi all, I thought I had done this and it was easy, but I can't find a solution: I want to test whether a xml tag has an attribute and vary the typeset content accordingly. There used to be \xmldoifelseempty, but that has been commented out (lxml-ini.mkiv). What else could I use? Here's a small test that shows what I'm trying to do: \startbuffer[test] <a> <b>some text</b> <b important="different">more text</b> </a> \stopbuffer \startxmlsetups xml:testsetups \xmlsetsetup{\xmldocument}{a|b}{xml:*} \stopxmlsetups \xmlregistersetup{xml:testsetups} \startxmlsetups xml:a \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:b \xmldoifelse{#1}{./[@important]} %\doifemptyelse{\expanded{\xmlatt{#1}{important}}} {\color[darkred]{NOTEMPTY: \xmlatt{#1}{important}}\par} {\color[darkblue]{EMPTY: \xmlflush{#1}\par}} \stopxmlsetups \starttext \xmlprocessbuffer{main}{test}{} \stoptext Hints appreciated! All best Thomas

Proposal for math mappings
by Aditya Mahajan 13 Dec '10

13 Dec '10

This is a proposal for a new way of selecting math mappings in MkIV. I want to get input from other math users whether this syntax would take care of all scenarios or not. There are five different ranges in mathematics: - digits (0..9) - lower case Latin (abc..z) - upper case Latin (ABC..Z) - lower case Greek (αβγ..ζ) - upper case Greek (ΑΒΓ..Z) A user may want to control what each range is mapped to. So, I suggest a setup command \setupmathmappings [ digits={style,alternative}, lclatin={style,alternative}, uclatin={style,alternative}, lcgreek={style,alternative}, ucgreek={style,alternative}, ] where the options for style are normal, bold while the options for alternative are normal, italic, sans, sansitalic, blackboard, script This command will the mappings for each range. **NOTE**: All combinations are not valid. A companion command \definemathmappings [whatever] [....] can be used to define multiple mappings. These mappings can be used by \setupmathmappings[whatever] (An alternative is that these mappings are activated using \whatever ...) For example, we can define a command to typeset vectors using \definemathmappings [vectors] [ digits={bold,normal}, lclatin={bold,normal}, uclatin={bold,normal}, lcgreek={bold,normal}, ucgreek={bold,normal}] \def\VEC{\groupedcommand{\setupmathmappings[vector]}{}} If later, we want to represent vectors as sans serif, we can use \definemathmappings [vectors] [ digits={normal,sans}, lclatin={normal,sans}, uclatin={normal,sans}, lcgreek={normal,sans}, ucgreek={normal,sans}] This interface makes it easy to switch math fonts for disiplines that want different style for different alphabet ranges. It is relatively easy to implement the above interface. All we need is some bookkeeping to set the right attributes. The default math mapping commands can be reimplmeneted using \definemappings. Before implementing this, I want to ask the opinion of other math users. Would the above interface take care of different use cases, or is it missing something? Finally, I am not too happy with the syntax. There are only a few ConTeXt commands in which the keys take a pair of values. Another option is to allow all 12 valid options normal, italic, sans, sansitalic, blackboard, script, bold, bolditlaic, boldsans, boldsansitalic, boldblackboard, boldscript with the variants sansitalic-italicsans, boldsans-sansbold, etc. as synonmyms. Which way of specifying the keys do you prefer? Aditya

Hello everyone. I am new to ConTeXt, but a frequent LaTeX user. I have got ConTeXt to compile simple text documents, and want to try to use the hvdm-exm.tex package (or module?) from http://tlcontrib.metatex.org/ When I try to load it with \usemodule I get the error module hvdm-exm not found I am using TeX Live 2010 on Mac OS X 10.6.4. Any thoughts? Jason T. Stein, B. Sc. (1998), B. Ed. (2002)

Hi! Why the following doesn't work? \def\mybuf{\startbuffer[a]b\stopbuffer} \mybuf Actually, I need slightly more advanced command, but this is the minimal example.

Hi all, cross reference is not worked in latest beta (MkIV) example: \starttext \placeformula[f] \startformula {\bf d}(t)=(1-t)^2{\bf b}_{0,0}+2(1-t)t\Big[\frac{1}{2}{\bf b}_{0,1}+\frac{1}{2}{\bf b}_{1,0}\Big]+t^2{\bf b}_{1,1}. \stopformula see (\in[f]) \stoptext -- Best regards, Huang Ze
