Drawing chemical structures

21 Nov '13

Dear Sirs, I'm trying to run some code from the ppchtex manual, however, the chemical structures are not correctly drawn. See the example: https://www.dropbox.com/s/w7v8kouc4glndf0/chemicerror.pdf.

Extra blank page after title page.
by john Culleton 21 Nov '13

21 Nov '13

Here is the code. first the file title.tex: ----------------- \startstandardmakeup[doublesided=no] (title stuff) \stopstandardmakeup ------------------- and next the file copy.tex: -------------------------------------- \startstandardmakeup[page=no] (contents) \stopstandardmakeup ------------------------ MY master file contains: \input title.tex \input copy.tex ---------------------- An extra blank page is inserted between the title page and the title verso. If I combine the two files into a new file combine.tex, eliminate the two input lines above and say \input combine.tex instead I still get the unwanted blank page in between.

Dear all, Presently I'm experiencing a problem with urls that, hopefully, the ME will demonstrate. It seems to me that something must have changed in the source since the end of september.

Numberconversion problem in caption prefixes
by Géry Ogam 21 Nov '13

21 Nov '13

Hello, There is a numberconversion problem in caption prefixes. For instance, if chapter numbers are set to Romannumerals, the conversion of the caption prefixes depends on the presence of a section Minimal example: \setuphead[chapter][conversion=Romannumerals] \setupcaption[way=bychapter, prefixsegments=chapter] \starttext \chapter{Cool} \placefigure{A cow}{\externalfigure[cow]} \chapter{Cat} \section{Mouse} \section{Dog} \placefigure{A cow}{\externalfigure[cow]} \stoptext The previous code displays an inconsistent caption prefix (first time a Romannumeral, second time a number): I Cool [figure] Figure I.1 A cow II Cat 2.1 Mouse 2.2 Dog [figure] Figure 2.1 A cow

EPUB woes
by Bill Meahan 20 Nov '13

20 Nov '13

I have been trying for a very long time to generate an epub document via context without success. I have followed the steps on the wiki to the letter, using the export-example file provided with the standalone distribution. A PDF generated from the file is exactly what I would expect from an example. The generated epub, however, is useless - all the text is jammed together into one continuous block with no formatting whatsoever. Adobe Digital Editions 2.0 crashes trying to open it. Sumatra and Sigil get it open but the results are as described above. Obviously I am missing a step or doing something wrong but I cannot see what. Context Standalone from a couple of days ago. Windows 7-64 (Home Premium) but I got the same results several months ago on a Linux system so I do not think it is OS-related.

Linespacing in TOC
by Jan Tosovsky 19 Nov '13

19 Nov '13

Dear All, I'd like to tweak a default TOC linespacing... I've 'invented' this: \setupcombinedlist[content][list=chapter, alternative=c] \starttext \title{Table of Contents} \setupinterlinespace[line=0.8ex] % too small, just for testing \placecontent \setupinterlinespace[line=2.75ex] %\setupinterlinespace[reset] \startfrontmatter \chapter{Intro}text text text \startfrontmatter \startbodymatter \chapter{Chapter}text \stopbodymatter \startbackmatter \chapter{Appendix}text \stopbackmatter \stoptext I cannot use simply the \completecontent command as the linespacing is effective already between the title and the first entry line... so I am splitting the title and the rest and set the linespacing just before list rendering. Finally I am resetting the value manually. The 'reset' keyword seems to be somehow ignored... Are there better ways to tweak linespacing in TOC ? Thanks, Jan

[***SPAM***] Textile
by Bill Meahan 19 Nov '13

19 Nov '13

To save possibly reinventing the wheel, has anyone written a filter for processing Textile markup analogous to the filters for Markdown and reStructuredText? I tried using Pandoc to provide multiple formats of output (ConTeXt, EPUB, MS Word) from a common source but Pandoc is excessively tied to Markdown which does not understand the difference between emphasized text and italic text and only outputs {\em word}, <em>word</em>, \emph{word} and so forth which means I have to go through every instance of the tag and change tags where I want explicit italics as I use other typographical techniques (small-caps or sans-serif or ...) for emphasis but some things (book titles, ship names, foreign words/phrases et. al) are always set in italics by convention. Pandoc continues its "map everything to <em> ways even if the input is textile or (X)HTML. There are some other neat advantages to Textile as well such as local styling (CSS or \begin{environment}... or \startenvironment ...) I know a lot of computer languages now and I really don't want to learn Lua or Haskell -- I'm retired! :) -- Bill Meahan, Westland, Michigan “Writing is like getting married.

Space before chapters
by Jan Tosovsky 19 Nov '13

19 Nov '13

Dear All, after two hours of investigating wiki and various commands I am giving up... Is there any way to set a bit of white space before my chapter title? (1) I've thought that before={\blank[20mm]} should do the job. It works for sections, but here I suspect it is ignored as my chapter start on a new page. (2) numbercommand=\groupedcommand{\blank[20mm]}{\blank[4mm]} - this works as expected, but only for numbered titles - I need it also for TOC and Preface. (3) commandbefore={\blank[20mm]} - it inserts the space between the number and title I have no idea what else to try... \setuphead[chapter][ alternative=middle, %before={\blank[20mm]}, %commandbefore={\blank[20mm]}, numbercommand=\groupedcommand{\blank[20mm]}{\blank[4mm]}, %numbercommand=\groupedcommand{}{\blank[4mm]}, ] \starttext \startfrontmatter \chapter{Intro}text \startfrontmatter \startbodymatter \chapter{Chapter}text \stopbodymatter \stoptext Any help is highly appreciated.

pst-spectra and some other pstricks packages in context
by DesdeChaves 19 Nov '13

19 Nov '13

Dear Sirs Tanks a lot for the context software. I use it so much. I'm a physics/chemistry teacher and for making personalized exams with random numbers/questions the math.random() from lua is great. For draw schematic diagrams/graphs with random arguments I use tikz inside luacode, like context("\\addplot[blue, ultra thick] {"..slope.."*x-"..workfunction.."};"). However, it would be useful to use some pstricks packages. For example, the package pst-spectra includes a set of spectrum of various chemical elements. It is unique. Currently, I run latex and then import the pdf file into context file. There are other old pstricks macros, but still very useful, that i like to use. It's old, but useful. In the pstricks home page (http://tug.org/PSTricks/main.cgi/) I can found some new work, with some new packages and macros. For now, if i try to run this simple code \usemodule[pstric] \starttext \startPSTRICKS \pspicture(0,0)(20,20) \psline(0,0)(20,20) \psline(1,1)(10,10) \endpspicture \stopPSTRICKS \stoptext I found this error message: [...] (/usr/local/texlive/2013/texmf-dist/tex/generic/pgf/utilities/pgffor.code.tex) `PSTricks' v2.43 <2013/05/12> (tvz) (/usr/local/texlive/2013/texmf-dist/tex/generic/pstricks/pstricks.con)) (/usr/local/texlive/2013/texmf-dist/tex/generic/pst-plot/pst-plot.tex v1.45, 2013/04/29 (tvz,hv) !

(critical edition) counter range in page
by Pablo Rodriguez 19 Nov '13

19 Nov '13

Hi Thomas, after thinking about the issue I wrote in my last message, I guess that implementing a general method with any counter could be better. I mean, implement three commands that could be applied to any counter: \getrangeinpage: first--last counter in page. \getfirstinpage: first counter in page. \getlastinpage: last counter in page. With first in page, as I wrote in my previous message, I don’t mean the first that happens in page, if the page doesn’t begin with it, but the last opened in previous page.. To be able to get the first in page and last in page is important in cases where works are divided in books and chapters. Information in headers should contain both. I think that the general method is a better approach (although I know that margin data aren’t counters [maybe this should be implemented in a different way]). I hope it helps, Pablo -- http://www.ousia.tk

(critical edition) verses and margin data ranges in page
by Pablo Rodriguez 19 Nov '13

19 Nov '13

Hi Thomas, I guess it might be interesting to have the following feature: a command that prints the range of lines on the page. \setupheadertexts[firstlineinpage--lastlineinpage] \getmarking[chapter] \starttext \startlinenumbering \dorecurse{200}{This is verse number \recurselevel.\\} \stoplinenumbering \stoptext I think this might be a command such as \getrangeinpage[linenumbering]. Also a similar feature would be useful for margin data (in critical editions, margin data are mainly for pages of canonical editions). In that case, the command could be something similar to: \definemargindata[Olearius] \getrangeinpage[Olearius] Two examples in which these could make sense: In any poetry edition (such as Homer’s works), verse ranges in page headers are extremely helpful for readers. For Plato or Aristotle, the Stephanus or Bekker pagination is important to locate passages. Having also the range in the headers could be very helpful to the reader. In this case, the range should start with the first margin data in page only if the page starts there. Otherwise, the last “open” margin data (from previous page) should start the range in page. I hope it helps, Pablo -- http://www.ousia.tk

Dear, long time since I have posted to the list but still a dedicated ConTeXt user… Now, I’ve upgraded to Mavericks. No way to use ConTeXt. I’ve also installed texlive 2013 and I installed the available updates. But still my ConTeXt is broken (I’m typesetting from TeXShop via GUI menu).

(critical edition) nesting linenotes
by Pablo Rodriguez 19 Nov '13

19 Nov '13

Dear Thomas, Luigi and Hans, my second sample might be related to the first one. But I’m not sure it is a bug. Here is the code: \setuppapersize[A8] \newcounter\MyCounter \def\CritApp#1#2{\increment\MyCounter% \startlinenote[Varia:\MyCounter]{#1] #2}#1% \prewordbreak\stoplinenote[Varia:\MyCounter]} \starttext \startlinenumbering \startlinenote[one]{hyphenated}this is a test on \startlinenote[two]{with nested linenote}hyphenation\prewordbreak\stoplinenote[two]\stoplinenote[one] \CritApp{this is a test on \CritApp{hyphenation}{nested linenote: bad line number}}{not hyphenated} \stoplinenumbering \stoptext A command such as \CritApp above is intended to generate all linenote references automagically. It works fine, but I cannot nest \CritApp linenotes. The problem is in within this line: \startlinenote[Varia:\MyCounter]{#1] #2}#1% If I replace "{#1] #2}#1" with {#2}#1, nesting \CritApp linenotes, everything works as expected. Is this a bug?

Hi, Thanks to Akira and Mojca the garden now ships 32 as well as 64 bit native windows binaries. I adapted the mtx-update scripts and setuptex and these are now included. If your machine is 64 bit, and the bins are 32 bit, one option is to -- run first-setup once -- then run first-setup with --platform=win64 keep in mind that you need to adapt your path (of set) or start a new console with setuptex (btw, better consoles than cmd are 'console2' and 'conemu') If all fails, then -- remove texmf-mswin -- download the installation zip and unzip it -- remove the status file -- run first-setup with "where luatex.exe" you can see what binary is taken the 64 bit versions run faster Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Therefore height used the global parameter \textwidth (defined in setuplayout) instead of the local parameter \textwidth (defined in definelayout[luxury]). Question: how to use the local one? \stoptext Best regards.

Integral limits
by Aditya Mahajan 19 Nov '13

19 Nov '13

Hi, In MkII, it was possible to change the limits on integrals using \setupmathematics[integral=...] % limits, nolimits, displaylimits that would affect how \int, \iint, \iiint, \oint, etc behaved. I can see two ways of definining a similar feature in MkIV. 1. Define \intop, \iintop, etc in char-def.lua and then somewhere define: \define\int{\intop\intlimits} \define\iint{\intop\intlimits} etc. 2. Define a new mathclass "intop" and use that in char-def.lua. Then, in the appropriate math-*.lua file, map intop to the appropriate macro. What would be the best way to go? Thanks, Aditya
