Subjects on this list - general request
by Robert Blackstone 20 Mar '13

20 Mar '13

Dear all, Considering all complaints about the difficulties to find, in the Garden, or in the NTG mail archive, answers to specific problems, wouldn't it be a good idea to ask everybody to clearly state the subject of their message, preferably starting with the most important keyword, and in particular to avoid (no subject) or [***SPAM***], and similar things as subjects. Also, if you forgive me, subjects like "upto current" or "Bug in \column" are not really helpful when on tries to search in the archive for a solution to a specific problem. In the last-mentioned example, wouldn't "\column, Bug in - " or even "\column, Bug in \column" be better? More specific subject titles in the mails might save some of us hours of unfruitful searching and lots of teeth grinding. This is probably not the first request on this topic but, if so, I thought it would do no harm to repeat it. Thanks in advance. Best regards, Robert Blackstone

date handling maltreated?
by H. van der Meer 20 Mar '13

20 Mar '13

Trying to do some date and time processing myself, I ran into problems caused by ConTeXt makeing it incompatibel with the original plain TeX itself! In the TeX-book, Appendix B one finds <citation> (Some parameters are set by TeX itself as it runs, so it is inappropriate to initialize them: \time, \day, \month, and year are established at the beginning of a job; .. </citation> Now the results in ConTeXT with a minimal example, put into the log for easier copying into the mail: \starttext \writestatus{}{\meaning\date -> \date} \writestatus{}{\meaning\day -> \the\day} \writestatus{}{\meaning\month -> \month WHY NOT monthname?} \writestatus{}{\meaning\year -> \the\year} \writestatus{}{\meaning\time -> \the\time} \stoptext Result: > \protected macro:->\dodoubleempty \syst_converters_date -> \date > \day-> 20 > macro:#1->\ctxcommand {monthname(#1)}-> \labeltext {unknown}HY NOT monthname? > \year-> 2013 > \time-> 989 Plain TeX here gives: \message{\meaning\day -> \the\day} \message{\meaning\month -> \the\month} \message{\meaning\year -> \the\year} \message{\meaning\time -> \the\time} \end Result: (./plaindates.tex \day-> 20 \month-> 3 \year-> 2013 \time-> 991 ) I strongly ask that ConTeXt abstains from changing the definition of \month and reverts to the exact result as given by plain TeX, i.e. a number in the range [1-12]. Because the change in ConTeXt makes it impossible to do calculations on the month. Furthermore I encountered problems with defining expanded macros for currentdate and currenttime. This seems impossible to accomplish, at least in a simple manner. See the results from these to examples: \edef\thedate{\currentdate}\writestatus{}{\meaning\thedate -> \thedate} \edef\thetime{\currenttime}\writestatus{}{\meaning\thetime -> \thetime} giving: > macro:->\currentdate -> \currentdate > macro:->\currenttime -> \currenttime This is most unhappy, because one really should be able to put the expansions of these macros somewhere. I hope the next beta will have solutions for these problems. Hans van der Meer

date problem
by H. van der Meer 20 Mar '13

20 Mar '13

There is a nasty problem when defining the \date. First approach: *** > macro:->\date \def\thedate{\date}\writestatus{***}{\meaning\thedate} Alas, I get lateron a luatex error on \date: ! LuaTeX error [string "\directlua "]:1: invalid escape sequence near '\d'. Second approach, use \edef to get an expanded value. \edef\thedate{\date}\writestatus{***}{\meaning\thedate} *** > macro:->\date Alas, the date is still the unexpanded macro and not something like 20 march 2013. How to? Hans van der Meer

Endnotes - How to place all endnotes in a separate chapter?
by Robert Blackstone 20 Mar '13

20 Mar '13

Dear list, How can I collect, in a separate (unnumbered) chapter at the end, or in the Backmatter, of a book, all endnotes from the previous chapters, as lists per chapter (for example in sections in this chapter "Notes", with, preferably, the chaptertitles as sectiontitles of that chapter) My setupfile contains, on the subject of notation, only: \setupnotation[endnote][way=bychapter,bodyfont=10pt] and each chapter now ends with: \placenotes[endnote][height=\textheight] which neatly gives a list at the end of each chapter. Thanks in advance for any advice. Best regards, Robert Blackstone

Here is a simple example: \starttext \startitemize[1,packed] Introduction text to the list below. \item some item text1 \item some item text2 \stopitemize I want to be able to adjust the vertical white space between the list introduction text and the list of items. How can this be accomplished? Wolfgang Schuster <schuster.wolfgang(a)gmail.com> wrote: > > Provide a example for this. > > Wolfgang

[***SPAM***] What am I doing wrong?
by d.henman 19 Mar '13

19 Mar '13

While reading the ConTeXt Manual I tried the following two commands, which didn't work. Here is the sample souce. \starttext First line. %\hskip With text here, this causes an compile time error. \hskip3em Indented?\crlf \hskip 3em Indented?\crlf \hskip3cm Indented?\crlf %\sym{on} This causes an error. %\sym{$\diamond$} This causes an error. %\sym{$\diamondsuit$} This causes an error. Last line. \stoptext What happened to \hskip and \sym ? Or what am I doing wrong? One further question. I tried nopping \before, \after, \between, and the none, and joinedup option but could not suppress white space occurring after \startitemize and the 1st \item. I tried looking in the garden as well, but had no luck. I believe th e information is in there but I couldn't find it after a hour or so. So please inform me as to how can tell ConTeXt how much space, including none, to place between the an item header (or none) and the list??? I'd appreciate the assistance in learning who to do this.

Including section number in reference broken
by Steffen Wolfrum 19 Mar '13

19 Mar '13

Hi, in October 2011 Marco asked how to get an output like this: I Foo A Bar subsection I.A The example he posted (see below) came to this result: I Foo A Bar subsection A Then Wolfgang added this line: \setupreferencestructureprefix[default][prefixsegments=2:*] But running this advice with todays beta does not have any effect one Marcos original example, and it does not lead to the desired ouput. Is this broken now? Steffen %%%%%%%%%%%%%%%%%%%%% \definestructureconversionset [myset] [ Romannumerals, Romannumerals, Romannumerals, Character, ] [numbers] \setuphead [sectionconversionset=myset] \setuphead [subsection] [sectionsegments=subsection] \starttext \startsection [title=Foo] \startsubsection [title=Bar, reference=bar] \stopsubsection \in{subsection}[bar] \stopsection \stoptext %%%%%%%%%%%%%%%%%%%%%

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)?
