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

Problem loading a font
by Mohammad Hossein Bateni 23 Dec '19

23 Dec '19

Hi, Here's a simple MWE: ============== \starttext Default {\definedfont[ALMFixed]ALM} Default \stoptext ============== I have the "ALM Fixed" font installed (otf from https://ctan.org/tex-archive/fonts/almfixed). I do not see any errors in the output. In particular, Context sees the font and the logs contain the following line: mkiv lua stats > loaded fonts: 3 files: almfixed.otf, latinmodern-math.otf, lmroman12-regular.otf Yet, the output from lmtx does not display the "ALM" string, though its place is reserved on the line. The same file typesets fine with mkiv. Thanks --MHB

Symbol Footnote Command
by Aykut Aykutt 23 Dec '19

23 Dec '19

Hi, I can change the mark of the second footnote from "2" to asterix by defining a conversion like so: %-- Working example, but it is not what I need -- \setupindenting[yes,small] \defineconversion[mymix][1,\m{*},2] \setupnotation[footnote][align={hz,hanging},indenting={yes,small,next},numberconversion=mymix] \startdocument This is the first sentence with a footnote.\footnote{This is the first footnote and its mark is "1".} This is the second sentence with a footnote.\footnote{This is the second footnote and its mark is "*". } This is the third sentence with a footnote.\footnote{This is the third footnote and its mark is "2". } \stopdocument Clearly this conversion repeats the marks "1", "*" and "2" repeatedly. Is there a way to define a new/special footnote command (say, "\symfootnote") which blends with normal footnotes, but prints footnotes with symbol marks (say, Set 2) and not with numbers. In other words, is it possible to achieve the same result as the working example above with something like the (pseudo) example below? %-- Pseudo example -- \setupindenting[yes,small] \def\symfootenote ?????????? \setupnotation[symfootnote][align={hz,hanging},indenting={yes,small,next}] \setupnotation[footnote][align={hz,hanging},indenting={yes,small,next}] \startdocument This is the first sentence with a footnote.\footnote{This is the first footnote and its mark is "1".} This is the second sentence with a footnote.\symfootnote{This is the second footnote and its mark is "*". } This is the third sentence with a footnote.\footnote{This is the third footnote and its mark is "2". } \stopdocument Thank you.

Disappearing font feature
by Rik Kabel 22 Dec '19

22 Dec '19

List, I have a strange case of a font feature disappearing when many fonts are used. In creating a sampler for the Jost* font (free at https://indestructibletype.com/Jost.html) and using its feature ss01 to get single-storey lower-case a, the font reverts to the default two-storey a when many weights are shown. When I create the fonts with \definefontfamily, the upright weights are fine and the italic weights revert. When I create the fonts with \definefont, the reverse is the case. Below is the demonstration for the \definefont variation and a snip of the failing result. \definebodyfontenvironment[13pt] [interlinespace=15pt] \setuplayout [backspace=0pt, topspace=30pt, width=middle, height=middle, location=middle, header=0pt, footer=0pt] \setuppagenumbering [location=] \definefontfeature [default] [default] [ss01=yes] \definefont [JHair] [jost-100-hairline] \definefont [JThin] [jost-200-thin] \definefont [JLigh] [jost-300-light] \definefont [JBook] [jost-400-book] \definefont [JMedi] [jost-500-medium] \definefont [JSemi] [jost-600-semi] \definefont [JBold] [jost-700-bold] \definefont [JHeav] [jost-800-heavy] \definefont [JBlac] [jost-900-black] \definefont [JHairI][jost-100-hairlineitalic] \definefont [JThinI][jost-200-thinitalic] \definefont [JLighI][jost-300-lightitalic] \definefont [JBookI][jost-400-bookitalic] \definefont [JMediI][jost-500-mediumitalic] \definefont [JSemiI][jost-600-semiitalic] \definefont [JBoldI][jost-700-bolditalic] \definefont [JHeavI][jost-800-heavyitalic] \definefont [JBlacI][jost-900-blackitalic] \startbuffer [Sampler] A B C D E F G H I J K L M N O P Q R S T U V W X Y Z a b c d e f g h i j k l m n o p q r s t u v w x y z à ë í ô ç 1 2 3 4 5 6 7 8 9 0 ` \texttilde\ - = ! @ \# \$ \letterpercent\ ^ \& * ( ) _ + [ ] \textbackslash\ ; ' , . / \{ \} \| : " < > ? \fontname\font \blank [line] \stopbuffer \setupalign [middle] \starttext \obeylines \JHair \getbuffer[Sampler] \JThin \getbuffer[Sampler] \JLigh \getbuffer[Sampler] \JBook \getbuffer[Sampler] \JMedi \getbuffer[Sampler] \JSemi \getbuffer[Sampler] \JBold \getbuffer[Sampler] \JHeav \getbuffer[Sampler] \JBlac \getbuffer[Sampler] \page \JHairI \getbuffer[Sampler] \JThinI \getbuffer[Sampler] \JLighI \getbuffer[Sampler] \JBookI \getbuffer[Sampler] \JMediI \getbuffer[Sampler] \JSemiI \getbuffer[Sampler] \JBoldI \getbuffer[Sampler] \JHeavI \getbuffer[Sampler] \JBlacI \getbuffer[Sampler] \stoptext Below is the demonstration for the \definefontfamily variation and a snip of the expected result, although the italics fail. \definebodyfontenvironment[13pt] [interlinespace=15pt] \setuplayout [backspace=0pt, topspace=15pt, width=middle, height=middle, location=middle, header=0pt, footer=0pt] \setuppagenumbering [location=] \definefontfeature [default] [default] [ss01=yes] \definefontfamily [up-one] [sansserif] [Jost] [tf={style:hairline,features}, bf={style:thin,features}, bi={style:light,features}, it={style:book,features}] \definefontfamily [up-two] [sansserif] [Jost] [tf={style:medium,features}, bf={style:semi,features}, bi={style:bold,features}, it={style:heavy,features}] \definefontfamily [up-three] [sansserif] [Jost] [tf={style:black,features}, bf={style:black,features}, bi={style:black,features}, it={style:black,features}] \definefontfamily [it-one] [sansserif] [Jost] [tf={style:hairlineitalic,features}, bf={style:thinitalic,features}, bi={style:lightitalic,features}, it={style:bookitalic,features}] \definefontfamily [it-two] [sansserif] [Jost] [tf={style:mediumitalic,features}, bf={style:semiitalic,features}, bi={style:bolditalic,features}, it={style:heavyitalic,features}] \definefontfamily [it-three] [sansserif] [Jost] [tf={style:blackitalic,features}, bf={style:blackitalic,features}, bi={style:blackitalic,features}, it={style:blackitalic,features}] \startbuffer [Sampler] A B C D E F G H I J K L M N O P Q R S T U V W X Y Z a b c d e f g h i j k l m n o p q r s t u v w x y z à ë í ô ç 1 2 3 4 5 6 7 8 9 0 ` \texttilde\ - = ! @ \# \$ \letterpercent\ ^ \& * ( ) _ + [ ] \textbackslash\ ; ' , . / \{ \} \| : " < > ? \fontname\font \blank [line] \stopbuffer \setupalign [middle] \setupbodyfont [up-one,13pt] \starttext \obeylines \ss\tf\getbuffer [Sampler] \ss\bf\getbuffer [Sampler] \ss\bi\getbuffer [Sampler] \ss\it\getbuffer [Sampler] \switchtobodyfont [up-two] \ss\tf\getbuffer [Sampler] \ss\bf\getbuffer [Sampler] \ss\bi\getbuffer [Sampler] \ss\it\getbuffer [Sampler] \switchtobodyfont [up-three] \ss\tf\getbuffer [Sampler] \page \switchtobodyfont [it-one] \ss\tf\getbuffer [Sampler] \ss\bf\getbuffer [Sampler] \ss\bi\getbuffer [Sampler] \switchtobodyfont [it-two] \ss\tf\getbuffer [Sampler] \ss\bf\getbuffer [Sampler] \ss\bi\getbuffer [Sampler] \ss\it\getbuffer [Sampler] \switchtobodyfont [it-three] \ss\tf\getbuffer [Sampler] \stoptext Assistance or explanation is welcome.

Tent style cards
by Pavneet Arora 22 Dec '19

22 Dec '19

Hello. I am trying to do up some tent style table place holder cards for my daughter's wedding, and have been wracking my brain for a solution for a couple of days now. Having tried many alternatives, this is the closest I have come up with. But mirroring doesn't work. If I use \setuparranging[2*4] mirroring works, but I only need tent style (1*2 head-to-head) so that I can trim to size. Any template that could be suggested would be most helpful as the wedding is on Mon (yikes!). advTHANKSance. >>>MWE<<< \definepapersize[tblcard][width=4in,height=3in] \setuppapersize[tblcard][letter,portrait] \setuparranging[2TOP] \setuplayout[ height=3in, width=4in, topspace=0in, header=0in, bottomspace=0in, footer=0in, backspace=0.0in, %% location=middle, marking=on, ] \startbuffer[tblcard] \strut \tfd A Name \stopbuffer \starttext \showframe \adaptpapersize[tblcard,mirrored][letter,portrait]\getbuffer[tblcard] \page \getbuffer[tblcard] \stoptext -- Pavneet Arora m: +1 647-406-6843 Waroc Informatik e: pavneet_arora(a)waroc.com

How to use together lmt_axis, lmt_grid and lmt_function
by Otared Kavian 22 Dec '19

22 Dec '19

Hi, I am experimenting the new LuaMetaTeX features introduced recently, but I can't get the built-in features together. To explain the problem I encounter, I want to draw the graph of a function on a grid in which the x-axis and the y-axis are alos drawn. Now lmtx has the « instances » (if I am not wrong…) named lmt_axis, lmt_grid and lmt_function which separately work fine, but I dont see how to use them simultaneously by keeping the correct scaling. In the minimal example below, copied from luametafun.pdf, the graph of the function $f(x) := (x - 1)^2$ should be drawn by showing its minimum at $x = 1$, and its value at $x = 0$ should be equal to 1. However the graph on the grid does not show this. Moreover the axes do not match the grid. This means that I have not understood how to give the same units and scales in the three instances lmt_axis, lmt_grid and lmt_function. Thanks for any help: Otared K. PS: here is a minimal example % begin grid-axis-function.tex \starttext \startplacefigure \startMPcode{doublefun} draw lmt_grid [ nx = 10, ny = 10, dx = 1, dy = 1 ] xsized 5cm withpen pencircle scaled .1pt withcolor "darkblue" ; draw lmt_axis [ nx = 10, ny = 10, dx = 1, dy = 1, ] xsized 5cm withpen pencircle scaled .5pt withcolor "darkred" ; draw lmt_function [ xmin = 0, xmax = 2, xstep = .05, ymin = 0, ymax = 1.5, code = "(x - 1)*(x - 1)", ] xsized 5cm withpen pencircle scaled .75pt ; \stopMPcode \stopplacefigure \stoptext % end grid-axis-function.tex
