Next problem with rfc4180splitter()
by Jaroslav Hajtmar 29 Sep '15

29 Sep '15

Hello ConTeXist, Some time ago, Hans solved my problem with the splitter. Now I solve correction an error in my module, which to me signaled Pablo Rodriguez. The problem is with jednosloupcovými CSV files, which thus do not contain separators row fields. Pablo say, that CSV files without colon contains separators, because line breaks are separators. Commas—or semicolons—are required when having more than a cell in the same line. For example LibreOffice Calc spares the final semicolon when only the file only contains one column and this behavior seems to be right, according to the RFC4180: Common Format and MIME Type for Comma-Separated Values (CSV) Files. We think that the final comma separator should optional, not mandatory. The following example shows, however, that rfc4180splitter () in onecolumn CSV file fails and falls with an error. Making I'm a mistake somewhere, or is something else wrong with the splitter? Thanx Jaroslav Hajtmar Here is minimal example: \starttext % mycsvfile.txt content one column data without separator: % a % b % c % d % e % f % myothercsvfile.txt content two columns data: % a,1 % b,2 % c,3 % d,4 % e,5 % f,6 \startluacode local mycsvsplitter = utilities.parsers.rfc4180splitter() -- local crap = io.loaddata("mycsvfile.txt") -- crashed (error code attempt to index field - a nil value) local crap = io.loaddata("myothercsvfile.txt") -- work fine local list, names = mycsvsplitter(crap) inspect(list) inspect(names) l = list for i = 1, 6 do context(l[i][1]..', ') end \stopluacode \stoptext

Re: [NTG-context] PPCHTEX: bonds overlaps the radicals groups

Can you provide me a very simple example? The idea is to draw the bond, then move, then the atom: \chemical [ONE,SB5,Z5,.2MOV1,Z0,.2MOV1,SB1,1.2MOV1,Z0] [H_3C,CH_2,CH_2] a bit sloppy, perhaps, but such is the syntax. On the other hand, one can make multiple calls to \chemical, thus making the code more readable. Alternately, one can shorten the bond segments which are defined as [.25,.75] of the bond length, but this turns out to be less aesthetic than adding small moves. One could imagine also to draw the text inside a framed box using a white background, as in \framed[frame=off,background=color,backgroundcolor=white]{\chemical{CH_2}} but I do not like this solution at all. I suppose that we could modify the underlying MP code to avoid extending any bond over the text box, but this would impose that the user draw the nodes before the bonds and would surely fail as one builds molecules in segments (unless the user be fully aware of the drawing process). We decided that this would be worse. Alan

table of contents
by Meer, Hans van der 28 Sep '15

28 Sep '15

I would like to restrict the tableofcontents to chapters only, leaving the sections etc. out. \completecontent does not seem the right command here. I am sure it is simple, but I don't see it. How to accomplish? Hans van der Meer

PPCHTEX: bonds overlaps the radicals groups
by DesdeChaves 28 Sep '15

28 Sep '15

Some time ago I wrote the code attached to create random branched organic molecules. However, with recent versions of Context the carbon-carbon bonds overwrites the radicals. How can I fix this? Another question: is there a way to change the bonds color? I would like to blank some radicals and bonds and ask the students to draw it. Thanks and have a nice sunday.

Ordered list of references (figures)
by Henning Hraban Ramm 28 Sep '15

28 Sep '15

Hi wizards, in my current book projects I need a list of figure references, ordered by author and page number. Like this: Photos: Hans Hagen (p.1,4,6,7), Taco Hoekwater (p.2,12–20), Hraban Ramm (p.3ff.) How can I do that? I.e. - How can I assign an author name/reference to a figure? – How can I output that list? About like this?: \placefigure[top][someref]{\externalfigure[somepic]}\reference[someref]{Hraban Ramm} \ref[t][someref] (\at{p.}[someref]) % put this in some command that is called by \listoffigures ? Extension: I need to integrate some unnumbered pages into the list, like the cover. Greetlings, Hraban --- http://www.fiee.net http://wiki.contextgarden.net https://www.cacert.org (I'm an assurer)

Question on register sort order and default method
by Rik Kabel 28 Sep '15

28 Sep '15

Why does the sort order (for registers, lists of synonyms, and so on) differ when no method is specified compared to when method=default is specified? That is, should not the default method applied when no method is specified be that named ‘default’? \setupregister[index][n=1] \starttext \index{Abc, def}\index{Abcdef, ghi}\index{abc, def}\index{abcdef, ghi} \subject{Placeindex with no explicit method} \placeindex \subject{Placeindex with \quote{default} method} \placeindex[method=default] \stoptext Where can documentation of the four defined methods (apparently: first, last, before, after, and default) be found? Where can documentation on the use of method mapping and cases, and unicode ordering, be found, or at least something not as cryptic as found on the mailing list <http://www.mail-archive.com/ntg-context%40ntg.nl/msg50454.html>[1]?

formatting section and figure numbers
by Meer, Hans van der 25 Sep '15

25 Sep '15

I do number my chapters with roman numerals with: \setuphead[chapter][conversion=Romannumerals] I would expect then that sections are numbered roman.arabic for example IX.1 This is not the case. While the chapter is numbered IX the sections are numbered 9.1 instead of IX.1. The numbering of floats with \placefigure luckily does the caption numbering right, i.e. there I see IX.1 as its number. Using \setuphead[section][conversion=Romannumerals] fails because then IX.I is produced, clearly not what is desired although the caption numbering is not influenced. Using \setuphead[section][number=no] does not help either, because then the captions loose their chapter number. What to do? Hans van der Meer

Hello, what is the name of a Lua function (if such function exists) which performs lookup for an image inside \externalimage? I'm asking especially due to the fact that the path here can be modified by [location={...}]. Best regards, Lukas -- Ing.

\hangindent and R2L alignment
by Wolfgang Schuster 23 Sep '15

23 Sep '15

Hi, there was a question on the Stackexchange site [*] with a problem for the \starthanging environment when the alignment is R2L. Here is shortened version of the example: %%%% begin example \useMPlibrary[dum] \starttext \starthanging[location=left]{\externalfigure[dummy][width=4cm,height=3\lineheight]} \input tufte \stophanging \blank \startalignment[righttoleft] \starthanging[location=left]{\externalfigure[dummy][width=4cm,height=3\lineheight]} \input tufte \stophanging \stopalignment \stoptext %%%% end example The problem is that \hangindent behaves the same for L2R and R2L alignment unlike the other formatting commands (\hangindent or \leftskip) for paragraphs. %%%% begin example \showframe[text][text] \setuphead [subject] [align=lefttoright, indentnext=yes] \starttext \startbuffer \subject{Normal paragraph} \input ward \subject{Leftskip} \start \leftskip 4em \input ward\par \stop \subject{Parindent} \start \parindent 4em \input ward\par \stop \subject{Hangindent} \start \hangindent 4em \hangafter -2 \input ward\par \stop \stopbuffer \title{Left to right} \startalignment[lefttoright] \getbuffer \stopalignment \title{Right to left} \startalignment[righttoleft] \getbuffer \stopalignment \stoptext %%%% end example [*] http://tex.stackexchange.com/questions/268688/correct-inconsistent-image-pl… Wolfgang
