Problem with definelabel and footnotes
by Rik Kabel 12 Jan '18

12 Jan '18

I have a document with hundreds of labels generated by \definelabel. They are used to index quotations in the text. Some of these occur in notes. Previously I had all such notes at the end of the book, as endnotes, but an editor requested a version with the notes as traditional footnotes. When the notes with labels appear in footnotes, the labels are not printed. The MWE below demonstrates the problem. I would expect to see a red 2 at the end of the first line of the footnote. I have tried to use \defineenumeration instead of \definelabel, but I cannot get a comparable result to what I have with definelabel. Is this a bug in the footnote typesetting, or a problem with my expectations? \setuppapersize[A6] \definelabel [Qi][text=,alternative=inright,headcolor=red] \definenote [pagenote] \setupnotation [pagenote][way=bypage,numberconversion=set 2] \definenote [endnote] \setupnotation [endnote][way=bytext,location=none,conversion=numbers] \starttext {\Qi}An index in the margin.\par Text with a numbered endnote with an index\endnote{% {\Qi}The numbered endnote with its index. The numbered endnote with its index. The numbered endnote with its index.% } and a marked pagenote with an index.\pagenote{% {\Qi}The marked pagenote, but where is the index? The marked pagenote, but where is the index? The marked pagenote, but where is the index?% }\par \page The endnote follows.\par \placenotes[endnote] \stoptext -- Rik Kabel

setting row height?
by Floris van Manen 29 Dec '17

29 Dec '17

What is the (preferred) way to set the height of table rows? e.g. the online documentation tells me how to set the width, not the height. or how to set the height of the table? \starttable[*{4}{|w(7mm)}|][textwidth=max]\HL[5] \VL[5]{1} \VL[1]{0} \VL[5]{2} \VL[1]{8} \VL[5]\AR\HL[1] \VL[5]{8} \VL[1]{~} \VL[5]{~} \VL[1]{1} \VL[5]\AR\HL[5] \VL[5]{0} \VL[1]{~} \VL[5]{~} \VL[1]{2} \VL[5]\AR\HL[1] \VL[5]{2} \VL[1]{8} \VL[5]{1} \VL[1]{0} \VL[5]\AR\HL[5] \stoptable Thanks .F

Can MetaPost draw directly datapoints from a data file?
by Jorge Manuel 28 Dec '17

28 Dec '17

When I need to draw datapoints from a external data file I’m using lua, like this: \starttext \startluacode Elemento = {} x = {} y ={} z= {} carga = {} i=1 context("\\startMPcode”) context("numeric u; u := 1.5cm;") for line in io.lines("molecule.xyz") do local a, b, c, d, e = string.match(line, '(%a+)%s*%s*(%S+)%s*%s*(%S+)%s*%s*(%S+)%s*%s*(%S+)') Elemento[i]= a x[i]= tonumber(b) y[i]= tonumber(c) z[i]= tonumber(d) carga[i]= tonumber(e) context("label(\"%s\", (%0.6f u, %0.6f u));", a, x[i],y[i]) i=i+1 end context("\\stopMPcode”) \stopluacode \stoptext Is there a way to pass directly the external data to MetaPost without using Lua? I know that I can use a similar function to gdata from graph.mp. I try to reuse this piece of code, but not works. \startMPcode vardef Grdln_@#(expr f) = save n_, s_; string s_; s_ = readfrom f; string @#[]; if s_<>EOF: @#1 := loptok s_; n_ = if @#1="%": 0 else: 1 fi; forever: @#[incr n_] := loptok s_; exitif @#[n_]=" "; endfor @#1<>" " else: false fi enddef; Grdln_$("molecule.xyz"); \stopMPcode Jorge

\vec{} arrow length?
by Alan Braslau 27 Dec '17

27 Dec '17

Why is the \vec{} arrow too short in some cases? Compare $\vec{X}$ to $\vec{Y}$. The MWE below looks wrong in the default font and is even uglier when pagella is used. Alan %\setupbodyfont [pagella] \starttext $\vec{X}$ vs. $\vec{Y}$ \stoptext

type and typing comments for TeX and Lua
by Pablo Rodriguez 27 Dec '17

27 Dec '17

Hans, sorry for insisting, but I really need this. I have the following sample: \definetype[context][option=tex] \definetype[lua][option=lua] \starttext \startTEXpage[offset=2em] a \TEX\ inline comment: \context{ag%befe} \Lua\ inline comment: \lua{agb --efe} \startTEX This is text. % a comment, not \comment \stopTEX \startXML This is text. \stopXML \startLUA if code=="code" then --this is a comment \stopLUA \stopTEXpage \stoptext Would it be possible that all comments in type and typing (at least, for Lua, XML and TeX) would have the same formatting for the whole comment contents, including the comment signs? Sorry, but with the current output, it is hard to see (for total newbies) what is part of the comment and what not. And the text editor will display something different. I’m afraid that the scite module isn’t an option for me. Many thanks for your help, Pablo -- http://www.ousia.tk

That should not be the case. Could it be, that the highlight-xml module fails to load? Please check your log file for a "module not found" entry. I have attached the result of my earlier sample. My module does not come in standard context. You have to download it from https://bitbucket.org/philexander/context-highlight. If general interest is high enough I can ask <whoever is responsible for this> to add it. Kind regards, Christoph

Dear Pablo, At least for XML you could use my module highlight-xml: \usemodule[highlight-xml] \definetype[xml][option=xml] \starttext \startTEXpage[offset=2em] \xml{attr="value"}\crlf \xml{This is text.} \startXML This is text. \stopXML \stopTEXpage \stoptext Note that even partial XML is highlighted correctly.

CSV parser fails when header is disabled
by Wolfgang Schuster 27 Dec '17

27 Dec '17

Hi, the rfc4180splitter function from util-prs.lua returns a empty table when the option to turn the first line into a header is disabled. The following example from the source %%%% begin example \starttext \startluacode local mycsvsplitter = utilities.parsers.rfc4180splitter() local crap = [[ "first","second","third","fourth" "1","2","3","4" "a","b","c","d" "foo","bar""baz","boogie","xyzzy" ]] local list, names = mycsvsplitter(crap,true) inspect(list) inspect(names) local list, names = mycsvsplitter(crap) inspect(list) inspect(names) \stopluacode \stoptext %%%% end example returns these tables: %%%% begin result table={ { "1", "2", "3", "4" }, { "a", "b", "c", "d" }, { "foo", "bar\"baz", "boogie", "xyzzy" }, } table={ "first", "second", "third", "fourth", } table={ } nil %%%% end result Wolfgang
