Drawing chemical structures
by DesdeChaves 21 Nov '13

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. I found this problem en Minimals (last version) and on TexLive 2013. \setupbodyfont[11pt] \usemodule[chemic] \starttext \startchemical[width=fit,scale=small,size=big] \bottext{α-Glycerophosphate} \chemical[ONE,SB1357,Z0357][\TL{α}{C},\SL{OPO\lohi{3}{2-}},H,H] \chemical[MOV1,SB137,Z037][C,\SL{OH},H] \chemical[MOV1,SB137,Z0137][C,H,\SL{OH},H] \stopchemical \definechemical[desoxyribose] {\chemical[FIVE,FRONT,BB125,+SB3,-SB4,Z4][O] \chemical[FIVE,FRONT,+R1235,+RZ1235][H,H,\SR{HOH_2C},OH] \chemical[FIVE,FRONT,-R1235,-RZ1235][H,OH,H,H]} \startchemical[height=6500,top=2000,bottom=2500,width=4500] \chemical[desoxyribose] \bottext{Desoxiribosa (dR)} \stopchemical \startchemical[height=4500,bottom=2500] \bottext{$\alpha$-D-Fructofuranose} \chemical [FIVE,FRONT,BB125,+SB3,-SB4,Z4][O] \chemical [FIVE,FRONT,+R1235,+RZ1235][\SR{HO},H,\SR{HOH_2C},CH_2OH] \chemical [FIVE,FRONT,-R1235,-RZ1235][OH,H,\SR{HO},H,CH_2OH] \stopchemical \startchemical[height=4500,bottom=2500] \chemical [FIVE,FRONT,B,R] \chemical [+RZ1..5] [1,2,3,4,5] \chemical [-RZ1..5] [a,b,c,d,e] \stopchemical \stoptext

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.

Re: [NTG-context] Space problem after formulas inside itemize environments

> What’s wrong with the second formula, both have the same space before and after the content? Then maybe Hans has corrected it recently. I am using ConTeXt version 2013.04.20, and you?

Problem with urls.
by Robert Blackstone 21 Nov '13

21 Nov '13

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. The example works with mkiv of 24 sept, but not with that of 3 november and later. --------------------------------------------------- \useURL[apurl][http://wiki.contextgarden.net/Category:Commands] \starttext \from[apurl] \url[apurl] \stoptext -------------------------------------------- I use TeXshop. The console gives me the following cryptic message about a LuaTeX error: \ctxcommand #1^^@-\directlua {commands.#1} \font_helpers_low_level_define ...caledfontmode )} \edef \somefontspec {at \n... \font_helpers_trigger_define ..._identifier_class \csname \v_font_identifier… \applyfontclassstrategies ...\fontface \endcsname \else \expandafter \font_h... \font_helpers_synchronize_font ...classstrategies \fi \setfalse \c_font_auto... \tt f-\ifmode \mathtt \else \normaltt \fi … l.5 \from[apurl] ? Thanks in advance for any help. Best regards, Robert Blackstone

Could you correct this space problem Hans? \startitemize \item Eeny, meeny, miny, moe \placeformula \startformula \text{Numbered formula: the space after is correct.} \stopformula \item Eeny, meeny, miny, moe \placeformula[-] \startformula \text{Unumbered formula: the space after is too big.} \stopformula \item Eeny, meeny, miny, moe \stopitemize

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

(critical edition) index to line number
by Pablo Rodriguez 20 Nov '13

Hi Thomas, I think it would be important to be able to index to the line number. Do you need a code sample for this? Many thanks for your help, Pablo -- http://www.ousia.tk

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.
