[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

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

Hi, I pploaded a new lmtx (no rpi 64 bins yet, one can pick these up from the build in a few days). Apart from a few fixes (older side float issue, some recent special rule related things) the only new thing is 'low level anchoring'. More can be found in ontarget.pdf (ontarget-anchoring.tex). It basically boils down to boxes listening to source, target and anchor keys, as in: \vbox source 123 \bgroup \offinterlineskip \blackrule[width=4cm,height=2cm,depth=0cm,color=darkred]\par \blackrule[width=4cm,height=0cm,depth=1cm,color=darkblue]\par \setbox\scratchboxtwo\hbox anchors "0004 "0001 % anchor "00040001 target 123 orientation 1 {\blackrule[width=2cm,height=1cm,depth=0cm,color=darkgreen]% \hskip-2cm \blackrule[width=2cm,height=0cm,depth=1cm,color=darkyellow]}% % \smash{\box\scratchboxtwo}% \egroup the mentioned document describes a bit higher interface (plugs into layers) .. all kind of experimental and meant as teaser for users who like low level stuff (playground). I also made it possible to use context \frules with leaders as in: test \leaders \frule height 6mm depth 3mm radius 1mm\hfill test \startuseMPgraphic{demoleader} fill unitcircle xysized (RuleWidth,RuleHeight+RuleDepth) withcolor RuleColor ; \stopuseMPgraphic test {\red \leaders \frule height 6mm depth 3mm type mp data {\includeMPgraphic{demoleader}} \hfill} test \startuseMPgraphic{demoleader} drawdblarrow (0,RuleHeight) -- (RuleWidth,RuleHeight) withpen pencircle scaled RuleThickness withcolor RuleColor ; \stopuseMPgraphic test {\red \leaders \frule height 1mm % we need at least some dimensions type mp line 1mm data {\includeMPgraphic{demoleader}} \hfill} test (leaders can have boxes, rules and also glyphs) In principle we can also have adaptive images (basically scaling) so I might make an example of that later (when i need it). Of course I'll fix things I broke this time, Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

Is there a syntax for making many index entry's all in one?
by Joel 28 Dec '21

28 Dec '21

I am using \index{} to populate \placeindex (an index) with items. I am wondering if there is any syntax that allows one \index{} command to define more than one entry, for example, something like this: \index{presidents+Lincoln, Abraham; Lincoln, Abraham} The result is two appearances in the index: LLincoln, Abraham Ppresidents Lincoln, Abraham Is there some syntax for making this possible, without calling \index{} multiple times? --Joel
