change numeral to string in Metafun
by dalyoung 14 Jul '10

14 Jul '10

Dear all, I'd like to draw boxes with a label in a certain rule. I define drawbox macro for it. It receives 3 numbers, (the height of box, x position, y position). I'd like to label the height of the box in the middle of the box. I tired label( h ,(3s*u+u, t*u + h*u/2)); %h is a received numeral. But it is not working. If I change h to "letter" in label command, it is working. So, I'd like to know how to put received numeral(the height of the box) as a label. Or, how to change the value of a variable to a string. Here is a working sample code. \startuseMPgraphic{sample} numeric u; u := 0.5cm; def drawbox (expr h, s, t) = %numeric h,s,t; draw unitsquare xyscaled (1cm, h*u) shifted (3*s*u, t*u); label("1",(3s*u+u, t*u + h*u/2)); enddef; drawbox (3, 0, 0); drawbox (6, 0, 3); drawbox (2, 1, 0); drawbox (1, 1, 2); drawbox (3, 2, 0) drawbox (4, 2, 3) \stopuseMPgraphic \starttext \placefigure[here][]{sample} {\useMPgraphic{sample}} \stoptext Thank you.

Dear ConTeXtuals, the following MP-inclusion produces fatal error (! TeX capacity exceeded, sorry [parameter stack size=6000].): starttext \startMPcode label(btex $\underbrace{a}_{b}$ etex,(0,0)); \stopMPcode \stoptext I use mkii, but the code should work. Has anyone an explanation? With many thanks for any hint Albrecht

\frac with Cambria
by luigi scarso 13 Jul '10

13 Jul '10

\usetypescript[cambria] \setupbodyfont[cambria,8pt] \starttext \inlinemath{\displaystyle\frac{(1-0.1) - 0.89803921568627}{1-0.1}}% {\switchtobodyfont[modern,8pt] \inlinemath{\displaystyle\frac{(1-0.1) - 0.89803921568627}{1-0.1}}} \stoptext IMO the numerator with cambria is too much distant from fraction's line: the same with LatinModern looks better. Denominator looks ok. -- luigi

parsing issue with \math{} inside natural table
by Brian R. Landy 13 Jul '10

13 Jul '10

Hi, I ran into a case where a natural table has an issue when it contains inline math and an alignment character is used. Here's a small example which triggers the problem: \starttext< \bTABLE< \bTABLEbody< \bTR< \bTD[alignmentcharacter={.},aligncharacter=yes]{\le 4.0\math{-}}\eTD< \eTR< \eTABLEbody< \eTABLE< \stoptext< However, if I replace \math{-} with $-$, the file works. Am I correct that $-$ and \math{-} should be interchangeable? Thanks, Brian

Here is a better patch, with new strings translated and v!appendix commented as in lang-ger.tex. I could also add support for Serbian latin, but I have no idea how to add new language that will allow both latin and cyrilic. -- Vedran Miletić

Serbian: Latin vs. Cyrillic

It would be great if ConTeXt supported: \mainlanguage [serbian] [script=latin | cyrillic] as well as \mainlanguage [english] [variant=american | british] etc. This is what Polyglossia does and I find it nice.

How to sort in Lua using locale?
by Mojca Miklavec 12 Jul '10

12 Jul '10

Hello, I would like to create a document using some functionality that is pretty close to creating an index, but the built-in index creation code doesn't suffice. My main question is: how do I sort strings using the built-in sorting rules for the current language? Here is an example with a table of names: names = { {first="Hans", last="Hagen"}, {first="Hartmut", last="Henkel"}, {first="Taco", last="Hoekwater"}, {first="Caron", last="Haček"} {first="Ančka", last="Car"} {first="Ana", last="Car"} {first="Anita", last="Car"} {first="Matija", last="Čop"} } and I want to print out the following: \section{C} \person{Car}{Ana} \person{Car}{Ančka} \person{Car}{Anita} \section{Č} \person{Čop}{Matija} \section{H} \person{Haček}{Caron} \person{Hagen}{Hans} \person{Henkel}{Hartmut} \person{Hoekwater}{Taco} The following code works for English and needs a fix to respect local sorting rules. I would be grateful for any hint before reinventing the wheel (the hint can also be a pointer to the right line of ConTeXt source code that does the sorting; I was a bit lost in the code). \mainlanguage[sl] \setuphead[section][style=\bf,before=\blank,after=,number=no] \def\person#1#2{\hbox{{\sc #1}, #2}} \starttext Code that needs fixing: \startluacode names = { {first="Hans", last="Hagen"}, {first="Hartmut", last="Henkel"}, {first="Taco", last="Hoekwater"}, {first="Caron", last="Haček"}, {first="Ančka", last="Car"}, {first="Ana", last="Car"}, {first="Anita", last="Car"}, {first="Matija", last="Čop"}, } -- this should sort with local sorting rules; how? function sort_names(a,b) if (a.last == b.last) then return a.first<b.first else return a.last<b.last end end -- this is extremely ugly and needs to be fixed -- with some UTF-8 library function first_letter(str) if (string.byte(str,1)>127) then return string.sub(str,1,2) else return string.sub(str,1,1) end end table.sort(names, sort_names) for k,v in pairs(names) do -- nested tables would also be an option; but are not required if (k==1) or (k>1 and (first_letter(names[k-1].last) ~= first_letter(v.last))) then tex.print(string.format('\\section{%s}', first_letter(v.last))) end tex.print(string.format('\\person{%s}{%s}', v.last, v.first)) end \stopluacode \crlf\crlf Desired result: \section{C} \person{Car}{Ana} \person{Car}{Ančka} \person{Car}{Anita} \section{Č} \person{Čop}{Matija} \section{H} \person{Haček}{Caron} \person{Hagen}{Hans} \person{Henkel}{Hartmut} \person{Hoekwater}{Taco} \stoptext Thanks a lot, Mojca

Example ConTeXt document: PS output
by Michael Talbot-Wilson 12 Jul '10

12 Jul '10

I've just installed ConTeXt "minimal" and had a look at "ConTeXt, The Manual". I typed in the example document that starts at the bottom of page 13 (called it eg.tex) and ran context. It produced the file eg.pdf and I notice that it ran luatex with the option "--backend=pdf". Thanks, those who have done massive amounts of advanced work on ConTeXt and luatex, huge projects which are costing me nothing. But, I have a problem. I have a PostScript printer. I'd prefer not to have to run pdf2ps. How can ps output be produced directly? "context --backend=ps eg" doesn't do it and there is nothing about --backend or other options in the index, of "ConTeXt, The Manual", as far as I can see. There's no Reference/en/backend on the wiki.

horizontal alignment
by Michael Goerz 11 Jul '10

11 Jul '10

Hi everyone, I'm trying to do some horizontal alignment, for typesetting poetry. There are lines that are continuations of the previous line, and should be aligned to the end of that previous line. Currently, I'm doing this by using \phantom text, which for some reason I also have to wrap into an \mbox to avoid a line break. As an example: \startlines here we now see you ~~ already in grief as you see ~~ yourselves ~~ as the last of the lasts we are mirrors of your consciousness \mbox{\phantom{we are mirrors of your consciousness} as you see the end} and you see us ~~ deep in the spring of the universe seeing you deep ~~ in the gravity well of the heat death we are dying ~~ in the spring as we watch you die we are grieving in the spring as you begin to grieve for all we are talking about bone-dry at the bottom of the well of time we are already parched \mbox{\phantom{we are already parched} for time is transparent} and we are all rats in the glassy \mbox{\phantom{and we are all rats in the glassy} labyrinth of time. \stoplines How would you solve this kind of problem? I've considered defining a macro \BrokenLine[line1][line2] that does the above. But, there are also instances where there are two or more lines as a continuation of one previous line. Maybe there is a possibility to mark a horizontal position temporarily, and then jump to that position later? Thanks, Michael
