Asking context to switch to a different font for a single character in many places
by Ajith R 02 Jan '22

02 Jan '22

Hi, I am trying to prepare a moderate sized document in Malayalam using Context. Overall I have been successful. However, there are a few rough edges for which I need help. This is the fifth problem I face. Is it possible to instruct Context to use a font in general, except for a single character? I want to show the space character with open box,␣ U+2423. However, the font doesn't have that character. The open box character shows up in many places within an otherwise Malayalam text. So, switching font is not possible. For the time being, I am using a substitution. However, I would like to know if it is possible. Thanks, ajith

enforcing formation of conjuncts inside \starttyping \stoptyping

Hi, I am trying to prepare a moderate sized document in Malayalam using Context. Overall I have been successful. However, there are a few rough edges for which I need help. This is the sixth problem I face. If I use Malayalam inside the command pair \starttyping \stoptyping, conjuncts are not formed as outside the command pair. Is it possible to enforce [features=malayalam-two] even inside \starttyping \stoptyping command pair? Thanks, ajith

[MetaFun] Trying to understand outlinetext, 'stretch' effect and \kerncharacters
by kauśika 01 Jan '22

01 Jan '22

Dear list, I have the following graphic \startuseMPgraphic{TitleGraphic} draw outlinetext.b (\MPstring{TitleText}) (withcolor "titlefg") (withcolor "titleoutline"); \stopuseMPgraphic which I tried to use as follows to produce a stylized 'title' head: \setupMPtext{TitleText}{% \starteffect[stretch]\bfc\namedstructurevariable{title}{title}\stopeffect} \useMPgraphic{TitleGraphic} [colors "titlefg" and "titleoutline" are set using \definecolor] But, the 'stretch' effect caused by \starteffect[stretch]…\stopeffect does not work with 'outlinetext' method in the MPgraphic. I have verified that the desired effect is produced using 'textext' method instead. But in that case I have to cheat (i.e draw twice; once with blownup) to get the text outline. Now, if I write instead \setupMPtext{TitleText}{% \kerncharacters[0.15]\bfc\namedstructurevariable{title}{title}} \useMPgraphic{TitleGraphic} then the desired effect is produced. As such, my purpose is served well by using \kerncharacters. Nonetheless, I request your kind help in understanding why this is happening and/or if I am doing something wrong. Thanks, kauśika

Malayalam character overlapping with footnote number
by Ajith R 01 Jan '22

01 Jan '22

Hi, I am trying to prepare a moderate sized document in Malayalam using Context. Overall I have been successful. However, there are a few rough edges for which I need help. This is the fourth problem I face. One character, ഼ U+0D3C, when used in \footnote[഼ ]{the foot note}, overlaps with the footnote number. How can I ask Context to provide extra space between the character and the footnote number? Thanks, ajith

Malayalam conjuncts
by Ajith R 01 Jan '22

01 Jan '22

Hi, I am trying to prepare a moderate sized document in Malayalam using Context. Overall I have been successful. However, there are a few rough edges for which I need help. This is the first problem I face. When I use the font RIT-Rachana from https://rachana.org.in/, my preferred font, one set of conjuncts are not formed correctly, while the rest are formed properly. The conjuncts that are not formed correctly are those where the second component is ര U+0D30, followed by a symbol that is shown on the right side of the conjunct viz ാ U+0D3E, ി U+0D3F, ീ U+0D40, ു U+0D41, ൂ U+0D42. If no symbols follow, or symbols follow on the left or on both sides, the conjunct is well formed.In the minimum working example given 5 is well formed, while the first conjunct in 6 is well formed and second ill formed conjunct. The conjuncts are well formed when used in Libre Office with the same font. Also, other fonts, for example, those from smc.org don't have this problem. Unfortunately, they don't support all symbols. One of the developers of the font thinks that this is probably a bug in Context. Hence, the reason for posting here. \definefontfamily [malayalam] [rm] [RIT-Rachana] [features=malayalam-two] \setupbodyfont [malayalam] \starttext 1. ശ്രീ 2. അശ്രു 3. ശുശ്രൂഷ 4. പ്രാസം 5. പ്രേയസി 6. പ്രോഗ്രാം \stoptext I am working on Debian 11. The font version is the latest 1.3. The command context --version gives mtx-context | ConTeXt Process Management 1.04 mtx-context | mtx-context | main context file: /home/ajith/Downloads/context-linux-64/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2021.12.25 00:58 mtx-context | main context file: /home/ajith/Downloads/context-linux-64/tex/texmf-context/tex/context/base/mkxl/context.mkxl mtx-context | current version: 2021.12.25 00:58 Thanks, ajith

Malayalam hyphenation
by Ajith R 01 Jan '22

01 Jan '22

Hi, I am trying to prepare a moderate sized document in Malayalam using Context. Overall I have been successful. However, there are a few rough edges for which I need help. This is the third problem I face. In most paragraphs, the sentences go beyond the right margin. How can I ask Context to break the word at the margin, without hyphenating every word manually? Thanks, ajith

footnotes not aligned if tabulate cell is centered.
by Ajith R 01 Jan '22

01 Jan '22

Hi, I am trying to prepare a moderate sized document in Malayalam using Context. Overall I have been successful. However, there are a few rough edges for which I need help. This is the seventh (and the last one for now) problem I face. When I use local footnotes within a tabulate section, the foot notes gets placed unevenly. If I remove the "c" from \starttabulate[|p(3cm)c|p|], then the footnotes are aligned. Is it a bug? If not, how can I correct it? \starttext \startlocalfootnotes \starttabulate[|p(10cm)c|p|] \NC [f]\footnote[f]{first foot note} first sentence\NC \NR \NC [s]\footnote[f]{second foot note} second sentence\NC \NR \NC \JustLeft{\placelocalfootnotes} \NC\FR \stoptabulate \stoplocalfootnotes \stoptext Thanks, ajith

Two questions on enumerations/indentation
by Mikael Sundqvist 31 Dec '21

31 Dec '21

Hi, I have two questions: 1) What is the correct way to indent the first line of a (serried) enumeration? In the example below, I can use headcommand, but then I do not know what I should replace "1em" below to fit the medium indenting. 2) I miss a numberstyle. What is the correct way to (in the example below) get Remark in italic and the number upright? /Mikael \defineenumeration[remark][ alternative=serried, width=fit, text=Remark, headstyle=italic, indenting={yes,medium}, %headcommand=\groupedcommand{\hskip 1em}{}, ] \starttext \samplefile{tufte} \startremark This line should be indented. The next line should not be indented. I wonder how we can fix that. This line is fine and is here for comparison. \stopremark \samplefile{tufte} \stoptext

Table of Contents Header?
by Michael Urban 31 Dec '21

31 Dec '21

I am playing around with imitating the design of fiction books from the early 20th century. The table of contents for these books often has small headings, 'CHAPTER' (or 'CHAP.') and 'PAGE' over the respective columns. How might this best be accomplished in ConTeXt? Just add a carefully formatted line before the \placecontent ? Or is there some more foolproof way of getting those headers into the right place?

Unicode superscript and subscript parentheses as operators
by Hans Åberg 30 Dec '21

30 Dec '21

Is it possible to use the Unicode superscript and subscript parentheses as superscript and subscript operators? That is, ⁽…⁾ having the same function as ^{…}, and ₍…₎ as _{…}. It might be something like the following, but somehow bundling the last part of \letcharcode into a command. \appendtoks \catcode`⁽=\activecatcode \letcharcode `⁽ ^{ \catcode`⁾=\activecatcode \letcharcode `⁾ } \catcode`₍=\activecatcode \letcharcode `₍ _{ \catcode`₎=\activecatcode \letcharcode `₎ } \to \everymathematics
