Coding for new Unicode characters
by Richard Mahoney | Indica et Buddhica 29 Dec '19

29 Dec '19

I am using Latin Modern Roman to typeset some proceedings and need the following characters in regular, italic, and small caps: Character: ṉ U+1E49 Name: LATIN SMALL LETTER N WITH LINE BELOW Character: Ṉ U+1E48 Name: LATIN CAPITAL LETTER N WITH LINE BELOW Character: ḻ U+1E3B Name: LATIN SMALL LETTER L WITH LINE BELOW Character: Ḻ U+1E3A Name: LATIN CAPITAL LETTER L WITH LINE BELOW Character: ṟ U+1E5F Name: LATIN SMALL LETTER R WITH LINE BELOW Character: Ṟ U+1E5E Name: LATIN CAPITAL LETTER R WITH LINE BELOW These characters are available in Computer Modern Unicode (although not, it seems, in small caps). Still, I would prefer to still with LM. I'm wondering if there is a way in Context to set up these characters on the fly, say with something along the lines of "newunicodechar"? \newunicodechar{<char>}{<code>} \newunicodechar{ā}{\accent"0304 a} newunicodechar -- Definitions of the meaning of Unicode characters https://ctan.org/pkg/newunicodechar?lang=en Best, Richard -- Richard Mahoney | Indica et Buddhica Littledene Bay Road Oxford NZ T: +6433121699 M: +64210640216 r.mahoney(a)indica-et-buddhica.org https://indica-et-buddhica.org/

How to use in Metafun, a function defined in Lua
by Otared Kavian 28 Dec '19

28 Dec '19

Hi all, I would like to use a math function defined in lua in Metafun in order to draw its graph, together with the graphs of some other functions. As a simple example consider the following: %%% begin lua-metafun-example.tex \startluacode function document.myfunction(n,x) local S S = math.sin(n*x) return S end \stopluacode \starttext Here \type{document.myfunction(n,x)} is $\sin(nx)$. For instance when $n = 2$ and $x = 355/113$ we have: \type{document.myfunction(2,355/113)} $=\cldcontext{document.myfunction(2,355/113)} \sim 0$. \startplacefigure[title={Nothing works\dots}] \startMPcode{GridAxis} numeric gu ; gu = 5mm ; % gu = graph unit draw image ( draw function (1,"x","document.myfunction(2,x)", % <-- this does not work % draw function (1,"x","sin(2*x)", % <-- this works -355/113,355/113,.01) scaled gu withpen pencircle scaled .075pt withcolor darkred ; ) xsized .7TextWidth ; \stopMPcode \stopplacefigure \stoptext %%% end lua-metafun-example.tex Here one sees that the function « document.myfunction » is well defined in Lua and is known in ConTeXt, but I cannot use it in a Metapost code: how can one do that? Thanks in advance for any help. Best regards: Otared

issues with attachments
by Pablo Rodriguez 27 Dec '19

27 Dec '19

Hi Hans, I accidentally discovered that file attachment generates two entries in Acrobat, such as this sample: \setuppapersize[A5] \showframe \setupinteraction[state=start] \setupinteractionscreen[option=attachment] \starttext a\attachment[file=xml-mkiv.pdf, name={attached.pdf}] \stoptext This happens with latest beta (from 2019.12.17) in both MkIV and MkXL. https://www.pdfa.org/wp-content/uploads/2018/10/PDF20_AN002-AF.pdf#search=u… warns about the use of both /EmbeddedFiles and /FileAttachment annotations. Acrobat seems to be the problematic software. I think it is fine to have /FileAttachment annotations for "method=normal" and /EmbeddedFiles for "method=hidden". Would be also possible that the entries in /Embeddedfiles use the value for "name" instead of "file" (when specified)? And for the /EmbeddedFile annotation, would it be possible to add the value for /Size entry (uncompressed size of the file in bytes, https://www.adobe.com/content/dam/acom/en/devnet/pdf/PDF32000_2008.pdf#page…) in the /Params dictionary? This is the way to avoid that Acrobat displays no uncompressed size but real uncompressed size (I guess both values would be very similar, when not the same). Many thanks for your help, Pablo -- http://www.ousia.tk

xml differences between old context and lmtx
by Jan U. Hasecke 27 Dec '19

27 Dec '19

Hi all, are there any documented differences between the xml features of normal context and lmtx? In a fun project I compile xml sources from www.deutschestextarchiv.de to pdf via context using xmlsetups which kinda works with normal context current version: 2019.08.09 18:29 With lmtx current version: 2019.12.12 01:08 I don't get a usable result. And there is a change in file naming I discovered. Files from the deutschestextarchiv have names like marx_kapital01_1867.TEI-P5.xml lmtx skips the TEI-P5 part Any hints how I can adjust my xmlsetups? juh

Is there a formal entity for ConTeXt to receive donations? What about receiving earnings?

Adjust kern for one character
by Rik Kabel 26 Dec '19

26 Dec '19

List, Is there a way in ConTeXt to adjust the left-side kern for one character? The cap J in the font I am using is being set too close to the preceding characters and I would rather not insert a thinspace before each. (Inserting a thinspace is sufficient, but finer control is welcome.) -- Rik

There is no mentioning in the red section that n is possible. However the n in the green section must be used as the symbol with n=123 or symbol=2. The n-key is used to set the number of columns when you set your items in multiple columns and it has the same effect as the two, three etc. keywords. The way how numbered items work is different. To change the symbol for the bullets or use numbers instead ConTeXt checks if the applies keywords include the name of a symbol (something you create with \definesymbol) or the name of a number conversion (something you create with \defineconversion) and applies it to the current entry. This check also you to create your own symbols or numbers orders by simply creating a new symbol and conversion. Wolfgang
