How to put a ___ before enumerations in ConTeXt?
by Joel 26 Nov '24

26 Nov '24

\starttext \defineitemgroup[numberunderlinelist] \setupitemgroup[numberunderlinelist][symbol=n, stopper={.~\blackrule[width=2em, height=0pt, depth=0.5pt]}, width=4em] \startnumberunderlinelist \dorecurse{100}{\startitem hello \stopitem} \stopnumberunderlinelist \stoptext I have used the above code to make enumerations looking like this: 1. ___ this is some text 2. ___ this is some text 3. ___ this is some text 4. ___ this is some text The underline is there for students to enter an answer, like a-d. The problem I find it is looks really messy putting the ___ between the numbering and text, such when you get to numbers that are wider, like 10., the ___ doesn't line up right. I also think its too confusing this way for students to know what to write. Is there a way to move the ___ bit out front of the number? It would look like this: ____ 1. this is some text ____ 2. this is some text --Joel

Zigzag left margin with italics
by Rik Kabel 25 Nov '24

25 Nov '24

In a paper I recently wrote I noticed some ugly zigzag alignment on the left margin of one paragraph (set with Libertinus) where a couple of book titles appeared at the start of the second and fourth lines. The following example demonstrates the issue. \definefontfeature [default] [default] [protrusion=quality,expansion=quality] \setupalign [hz,hanging] \startbuffer Here is a line of text, the first sentence in the demonstration.\\ {\em Then} the next sentence in the paragraph follows.\\ You can see that the italic {\em T} appears to be a bit indented.\\ {\em There } might be a way to shift it to the left that little bit.\\ Perhaps a protrusion setting.\\ {\em This} does appear to depend to on the font used. With Modern and\\ Libertinus it is worse, with Times a bit better. \blank \stopbuffer \starttext Modern\\ \getbuffer Times\\ \setupbodyfont[times] \getbuffer Libertinus\\ \setupbodyfont[libertinus] \getbuffer \stoptext How can one set a small left-margin protrusion for the italic T and possibly other characters? I know it is a small issue, but once seen it is hard to un-see. -- Rik

A few question about defining symbols and creating downarrow to illustrate function rules
by Jethro Djan 25 Nov '24

25 Nov '24

Hello, I have a few questions. 1. What is the best way to get a symbol from a font you are not using as your main? %% start MWE \starttext \definesymbol[cedis][\utfchar{“20B5}] \def\cedis{ \switchtobodyfont[dejavu]\tf\symbol[cedis] } I have GH\cedis 10.00 in my pocket \stoptext %% end MWE I tried to use \getglyph because I saw it being used in a similar way (but not with unicode characters) like this: \definesymbol[cedis][\getglyph{dejavu}{\utfchar{"20B5}}] It didn't work. 2. I would like a more robust method to create a diagram (ie., a series of input and outputs where you are then required to tell the rule of the mapping). The inputs will be up with the outputs below and a downward pointing arrow between them. %% start MWE \starttext \define[2]\xdownarrow{ \startframed[frame=off,offset=0pt,width=0.8cm] \startMPcode numeric u, w; u := .3cm; w := 2pt; pair pointX, pointY; path pointXY; pointX := origin; pointY := pointX shifted (0,-3u); draw pointX -- pointY withpen pencircle scaled .6w; drawarrow pointX -- pointY withpen pencircle scaled .6w; labeloffset := u; label.top (textext("\dm{#1}"), pointX); label.bot (textext("\dm{ #2 }"), pointY); \stopMPcode \stopframed } \startitemize[n] \item Find the rule of the mapping: \startplacefigure[location=none] \startframed[frame=off,offset=0pt,] \xdownarrow{x}{y} \hspace[big] \xdownarrow{1}{3} \hspace[big] \xdownarrow{2}{1} \hspace[big] \xdownarrow{3}{-1} \hspace[big] \xdownarrow{4}{-3} \hspace[big] \xdownarrow{5}{-5} \stopframed \stopplacefigure \startitemize[a] \item \im{y = 2x + 2} \item \im{y = -2x + 2} \item \im{y = 4x} \item \im{y = -2x + 5} \stopitemize \stopitemize %% stop MWR How can I achieve this more elegantly with better spacing and the arrow pointing to the number instead (-) for negative numbers? Regards, Jethro

Arranging sometimes adds a zero
by Max Chernoff 25 Nov '24

25 Nov '24

Hi Hans, The recent discussion of imposition reminded me of an arranging bug that I found a little while ago. MWE: \setuppapersize[A5,landscape][A4] \setuparranging[2TOPSIDE] %% Uncomment to "fix" the bug % \protected\expandafter\def\expandafter\fixedspace\expandafter{% % \fixedspace% % \setbox\scratchbox\emptybox% % } \starttext \dorecurse{4}{\samplefile{knuth}} \stoptext With this example, there is an extra page on page 2 that contains nothing but a "0" in the bottom left corner. Clearing \scratchbox before the imposition code runs seems to fix this, but I wasn't able to trace it any further. Thanks, -- Max

Due to the sheer amount of possibilities combined with my current lack of full understanding how parameters work, what would be the (simple) way to layout an existing pdf containing A5 pages in to groups of booklets different from all or 4 A4 sheets each (32 pages of the pdf) e.g. the 2*2*4 does generate a booklets containing 4 sheets with 16 pages. Is there a way to change the number of sheets to bundles of 5 or 8 ? .F

Metafun : reuse a static picture
by Fabrice L 24 Nov '24

24 Nov '24

Dear list, I have some difficulty to reuse a static picture in a multipage MetaFun document. I wish to define a complex image, with graphic and texts, and manipulate this image at each page. As the minimal working example shows, if I define a particular picture in the variable « AnImage » and a random text in another picture called « AnotherImage », I can use these two pictures in the first page of the document, but only one of them appears in the second page of the document (with the same code). I know that if I replace startMPinclusions/stopMPinclusions by startMPinitializations/stopMPinitializations, this works, but the image is recalculated (a different number is drawn), and I do not want this since the image is complex and takes time to make. So the question : how to make the two pictures « AnImage » and « AnotherImage » appears in the both page ? Thanks for any help ! Fabrice, % MWE : % 8< --------------------------------------- \starttext \startMPinclusions picture AnImage , AnotherImage; AnImage := image ( draw fullcircle scaled 40; ); AnotherImage := image ( arandomnumber := uniformdeviate(1); draw textext(decimal(arandomnumber)) scaled 0.5; ); \stopMPinclusions \startMPpage draw AnImage ; draw AnotherImage ; \stopMPpage \startMPpage draw AnImage ; draw AnotherImage ; \stopMPpage \stoptext % 8< ---------------------------------------

\shiftdown
by Thomas Meyer 24 Nov '24

24 Nov '24

Hi guys, I would like to move the first capital letter of a term down so that the rest of the term ends up approximately in the centre of the capital letter. The capital letter should be larger than the rest and is not a problem in itself. However, I can't manage this with \shiftdown. It always shifts down at a fixed distance. And I can't work with \setupshift. The inputs of unit=pt, dy=5 etc. don't seem to do anything, at least nothing happens with \shiftdown. Any help would be appreciated Greetings Thomas

Remove umlauts etc. from input
by Wolfgang Schuster 24 Nov '24

24 Nov '24

Hi, is there an already existing option to reduce umlauts etc. to ascii counterparts, e.g. \starttext Füße \stoptext results in Fusse The fonts manual gives an example for a font feature with the desired output but it's possible I missed something or there is a better solution. \startluacode local shapedcodes = { } for k, v in next, characters.data do local s = v.shcode if s then if type(s) == "number" then shapedcodes[utf.char(k)] = { utf.char(s) } elseif #s == 2 then shapedcodes[utf.char(k)] = { utf.char(s[1]), utf.char(s[2]) } end end end fonts.handlers.otf.addfeature { name = "simplify", type = "multiple", data = shapedcodes, } \stopluacode \definefontfeature [simplify] [simplify=yes] \starttext Füße \feature[+][simplify]Füße \stoptext Wolfgang
