serial letters
by Henning Hraban Ramm 11 Nov '24

11 Nov '24

How would you approach serial letters, e.g. to all members of a club? (Actually I need to send out donation receipts.) I’d like to use the letter module, since my usual letter design is using it. I can export the addresses to CSV, JSON, Lua tables or whatever or transfer them to a SQLite db. Would it make more sense to read them in Lua and combine this data with a buffer, or to write a single tex file for every letter? I know how to do the latter, but I’d like to learn a more ConTeXt-ish way. Would it make sense to use the bibliographies module?

Hi, Please find attached a new version of the module, with some ideas from Marco. Later, I'll upload it to modules.contextgarden.net. Here a usage example: \usemodule[downsample] \setupexternalfigures[ location=default, % find hacker.jpg and mill.png cache=/tmp, % where to put the low resolution images resolution=50, % resolution in DPI conversion=downsample.pdf] % use this module \starttext \externalfigure[hacker][width=0.4\textwidth] \setupexternalfigures[resolution=20] \externalfigure[mill][width=4in, height=3in] \setupexternalfigures[resolution=200] \externalfigure[mill][width=4in, height=3in] \stoptext Hans, it would be nice, to apply this patch, to trigger new conversion, when figure dimensions change: --- grph-inc.lua~ 2019-02-14 17:04:12.000000000 +0100 +++ grph-inc.lua 2019-02-17 08:45:38.129971581 +0100 @@ -864,6 +864,14 @@ newbase = prefix .. newbase end local hash = "" + local width = figures.current().request.width + local height = figures.current().request.height + if width then + hash = hash ..

Status of Asymptote
by Alexandre Christe 11 Jan '24

11 Jan '24

Dear all, I'd like to know what is the status of Asymptote in Context. To my knowledge, metapost/metafun only support 2D (except with the additional libraries from Roegel, which would have to be cleaned up a bit). Otherwise, what shall be used for 3D drawings in Context? TikZ? Something else? Thanks in advance. Alex

Re: [NTG-context] checkbox in fields show the word yes
by Andres Conrado Montoya 05 Oct '23

Firefox doesn't show the "yes", nor Acrobat X, but SumatraPDF does. I modified your definition as: \definefield[test][check][cbox][][] And now the "yes" doesn't appear. However, I don't know how this affects the functionality of the form. -- Andrés Conrado Montoya Andi Kú andresconrado(a)gmail.com http://sesentaycuatro.com http://messier87.com http://chiquitico.org ---------------------------------------- Los fines no justifican los medios, porque la medida verdadera de nuestro carácter está dada por los medios que estamos dispuestos a utilizar, no por los fines que proclamamos. ---------------------------------------- “You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it.

Dear all, I'm struggling to setup a nested itemize with no blank line and several columns. What I mean is something like 1. a) bla c) bla b) bla d) bla The following MWE is my starting point \starttext \startitemize[n] \item \blank[-line] \startitemize[a,horizontal,two] [margin=2cm] \item First \item Second \item Third \item Fourth \stopitemize \item \blank[-line] \startitemize[a,horizontal,columns,two] \item First \item Second \item Third \item Fourth \stopitemize \stopitemize \stoptext Thanks in advance

new uplaod
by Hans Hagen 17 Apr '23

17 Apr '23

Hi, I uploaded a new lmtx. Again some updated math of which details will be revealed later. Apart from some details we added suport for fourier notations. There are no high level definitions yet as we have to invent names but this is how it works (private unicode slots might change): \setupbodyfont[pagella] \starttext \setupmathdelimited [topoffset=.2\exheight] \definemathdelimited [fourier] [rule=no, left=\zerocount, right="FE944] \definemathdelimited [courier] [rule=no, left=\zerocount, right="FE946] \definemathdelimited [xourier] [rule=no, left=\zerocount, right="FE948] $ \fourier{(z+1)} $ $ \fourier{(z+1)} + \sqrt[2]{1}$ $ \fourier{(z+1)} + \courier{(z+1)} + \xourier{(z+1)} $ $ \fourier{\left(z+\frac12\right)} + \courier{\left(z+\frac12\right)} + \xourier{\left(z+\frac12\right)} $ $ \autofences \fourier{(z+\frac12)} + \courier{(z+\frac12)} + \xourier{(z+\frac12)} $ $ \widehat{x^2 + 2x + 2} $ \stoptext This example also shows a new \autofences feature and widehats (widetilde and widecheck also work that way) that overcome limitations in fonts, so \def\CrappyHack#1{\im{#1{a} + #1{a+b} + #1{a+b+c} + #1{a+b+c+d} + #1{a+b+c+d+e} + #1{a+b+c+d+e+f}}\par} \CrappyHack\widehat \CrappyHack\widetilde \CrappyHack\wideacute \CrappyHack\widecheck will work. For thise in finance we now have $ \annuity{x + 1} + \lannuity{x + 1} + \rannuity{x + 1} + \lrannuity{x + 1} $ these are basically radicals (like sqrt) with two sided symbols.

Convertnumber with \ref[number] fails in MkIV, works in LMTX
by Rik Kabel 06 Dec '22

06 Dec '22

Hello list, The following fails with ConTeXt ver: 2021.10.24 21:45 MKIV but works with the companion LMTX. The error message is:tex error > tex error on line 6 in file G:/TestConTeXt/convert.tex: ! Incompatible glue units , pointing to the second \convertnumber line. \definelabel[XX]%[text=,before=,after=,alternative=inright] \startTEXpage[offset=2em] abc\XX[xx]\par \ref[number][xx] · \convertnumber{r}{1} · \convertnumber{R}{\ref[number][xx]} \stopTEXpage In this case I am trying to display with roman numerals the number generated in the label created through \definelabel. Suggestions welcomed. -- Rik

Suboptimal German hyphenation
by Leah Neukirchen 31 Oct '22

31 Oct '22

Hi, I was typesetting some German text on a narrow page when I discovered the justification wasn't as good as expected. I think I tracked this down to differences in hyphenation points, namely, ConTeXt has fewer: \starttext \language[de] \showhyphens{Zusammenhang} \showhyphens{anderswo} \showhyphens{anderswoher} \stoptext This shows languages > hyphenation > show: Zusam[-||]men[-||]hang languages > hyphenation > show: anderswo languages > hyphenation > show: anders[-||]wo[-||]her Now with LaTeX and Babel: \documentclass{article} \usepackage[ngerman]{babel} \begin{document} \showhyphens{Zusammenhang} \showhyphens{anderswo} \showhyphens{anderswoher} \end{document} This shows [] \TU/lmr/m/n/10 Zu-sam-men-hang [] \TU/lmr/m/n/10 an-ders-wo [] \TU/lmr/m/n/10 an-ders-wo-her The LaTeX hyphenation points agree with the German Duden dictionary. As none of the words use more than 7-bit ASCII, I think newer pattern changes are not related. Curiously, the same effect already appears with MKII and MKIV from TeXLive 2014, the oldest I had around. I'm also surprised 'anders-wo-her' gets hyphenated but 'anderswo' is not hyphenated at all. I could not reproduce a difference with English words so far. Any ideas? As far as I understand, MKIV/LMTX should use the de-hyph-1996 patterns which LuaLaTeX uses these days too, via hyph-utf8. Thanks, -- Leah Neukirchen <leah(a)vuxu.org> https://leahneukirchen.org/
