How to make a block of text narrower?
by Joel 15 Nov '22

15 Nov '22

I need to make a section of text in my document narrower, about .6666\textwidth. Basically the text has normal alignment and everything, just instead of filling \textwidth, its compressed so there is a larger white space to the right. I've tried dozens of things, but cannot get a good solution, every solution has strange other effects. The best thing that has worked so far is \setuplayout[width=3in] But the problem with this solution is then I cannot get it to return to the original settings afterward. --Joel

new upload
by Hans Hagen 15 Nov '22

Hi, I uploaded a new version. New is that we can apply hz to math, although currently we have configured it as experiment. \setupbodyfont[pagella] % \startluacode % fonts.expansions.vectors.math = { % [0x002B] = { 4, 0 }, -- + % [0x2212] = { 4, 0 }, -- - % [0x003C] = { 8, 0 }, -- < % [0x003D] = { 8, 0 }, -- = % [0x003E] = { 8, 0 }, -- > % [0x002F] = { 2, 0 }, -- / % [0x0028] = { 2, 0 }, -- ( % [0x0029] = { 2, 0 }, -- ) % [0x005B] = { 2, 0 }, -- [ % [0x005D] = { 2, 0 }, -- ] % } % \stopluacode \setupmathematics[hz=yes] \startbuffer \showglyphs \dorecurse{20}{\strut test $x + y/2 - w = 10$ }\unskip \stopbuffer \definecolor[tgreen][g=1,t=.5,a=1] \definecolor[tred] [r=1,t=.5,a=1] \startTEXpage[offset=5dk] \startoverlay {\ruledvbox to 5cm{\setupalign [tolerant,stretch]\tgreen\getbuffer\vss}} {\ruledvbox to 5cm{\setupalign[hz,tolerant,stretch]\tred\getbuffer\vss}} \stopoverlay \stopTEXpage \stoptext Normally an expansion factor is small and used for both stretch and shrink, but we can have them independendent. So, here we stretch rather extreme but don't shrink. \setupmathematics[hz=yes] only kicks in when we have hz enabled as alignment option. We can of course configure more 'stretchable symbols' but first we want to know if it makes sense at all. We can also imagine to disable it in specific cases.

\xmldocument vs #1 in \xmlsetsetup
by denis.maier＠unibe.ch 14 Nov '22

14 Nov '22

Hi, most examples in the mkiv-xml manual use #1 with \xmlsetsetup, e.g. \startxmlsetups xml:demo:base \xmlsetsetup{#1}{document|section|p}{xml:demo:*} \stopxmlsetups However, in quite a few occasions I've noticed the usage of \xmldocument instead of #1. What exactly is the difference ? When should you prefer one over the other? Best, Denis

\definemeasure / \dimexpr
by Henning Hraban Ramm 13 Nov '22

13 Nov '22

I’m constantly struggling with dimension calculations. Is there anything I can read about the possibilities and limitations? e.g. with \definemeasure[PageWidth][132mm] none of the following works: \definemeasure[FlapWidth][0.8 * \measure{PageWidth}] \definemeasure[FlapWidth][.8\measure{PageWidth}] \definemeasure[FlapWidth][\measure{PageWidth} * 0.8] \definemeasure[FlapWidth][\measure{PageWidth}*8/10] \definemeasure[FlapWidth][8\measure{PageWidth}/10] Hraban

How to stop enumerated tabulate environments from shifting to the right?
by Joel 12 Nov '22

12 Nov '22

When I place a tabulate environment inside itemize, it indents and the entire table is shifted to the right about 1/2". \starttext \input knuth \startitemize[n] \item x \stopitemize \startitemize[n] \starttabulate[|lp(.1\textwidth)|cp(.35\textwidth)|cp(.2\textwidth)|cp(.35\textwidth)|] \NI \NC \NC \NC\NR \NC \NC \NC \NC\NR \stoptabulate \stopitemize \input knuth\stoptext See this code which when compiled, the first itemize numbers line up with the left edge of text, but the one with tables indents. It also seems to spill into the right margin. How can I stop enumerated table environments from indenting? --Joel

LMTX: reimplementing texquotes as OTF feature
by Leah Neukirchen 12 Nov '22

12 Nov '22

Hi, as Hans recommended in the last video meeting, I tried to implement the texquotes feature using OTF features, and hit two problems: 1) To support German quotes as well, I have two ligatures that end up as the same glyph: `` -> “ "' -> “ This can't be in the same ligature feature, as it will overwrite the table entry with a duplicate key. After some fiddling, I decided to map "' to a Unicode PUA symbol and then add a second feature that maps this symbol to “ using the substitute feature. This works for TeX Gyre Schola. But perhaps someone knows a nicer way. 2) This approach doesn't work for lmodern or palatino, I still get "' as inch-sign/quote there... anything else I need to tweak for these fonts? \startluacode fonts.handlers.otf.addfeature { name = "texlig", type = "ligature", data = { ['“'] = { "`", "`" }, ['”'] = { "'", "'" }, ['„'] = { '"', "`" }, [''] = { '"', "'" }, ['‘'] = { "`" }, ['’'] = { "'" } } } fonts.handlers.otf.addfeature { name = "texsub", type = "substitute", data = { [''] = '“', } } \stopluacode % with lmodern or palatino it breaks \setupbodyfont[schola] \definefontfeature[ltest][texlig=yes,texsub=yes,trep=no] \addff{ltest} \starttext ``foo'' `foo' "`foo"' 19" rack \stoptext Thanks, -- Leah Neukirchen <leah(a)vuxu.org> https://leahneukirchen.org/

how to simulate \hss in luametatex?
by 黄复雄 11 Nov '22

11 Nov '22

Hi list, I want to simulate \hss in lua end in ConTeXt/luametatex environment. For example, ```ConTeXt a{\raise 1.5ex\hbox to 0pt{\hss b}}c ``` should get 'b' on top of 'a', as follows: ```pdf b ac ``` and in lua, I see a <glue userskip> before "b" node, width width:0, stretch:65536, shrink:65536, stretchorder:2, shrinkorder:2 And in lua, I do as follows(part of my app seen in attachment): ```lua local hss = node_new(glue_id) hss.stretch = 65536 hss.stretchorder = 2 hss.shrink = 65536 hss.shrinkorder = 2 hss.width = 0 list,_ = node_insertbefore(list, list, hss) -- b is in the list -- I got a <glue userskip> with width:0, stretch:65536, shrink:65536, stretchorder:2, shrinkorder:2 local box = node_new(hlist_id, "box") box.head = list box.width = 0 box.shift = -tex_sp("1ex") -- I got <hlist box> width:0 height:0 deep:0 shift: -503424 head, current = node_insertbefore(head,current, box) -- current is 'c' node ``` And got 'b' on top of 'c' in pdf as follows: ```pdf b ac ``` How can I get 'b' on top of 'a' as \hss do? ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context(a)ntg.nl / https://www.ntg.nl/mailman/listinfo/ntg-context webpage : https://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : https://contextgarden.net ___________________________________________________________________________________

Page break with placement of a figure at the bottom of the page
by Fabrice Couvreur 10 Nov '22

10 Nov '22

Hi, I find that for some time (but maybe the problem comes from me !), the placement of a figure at the bottom of the page causes a page break when it seems to me that there is enough space, which poses some problems in the pagination of my documents. Thanks. Fabrice \useMPlibrary[dum] \definelayout [1] [topspace=10mm, header=15mm, headerdistance=10mm, height=middle, width=middle, location=middle] \setuplayout [topspace=10mm, header=0pt, headerdistance=0pt, height=middle, width=middle, location=middle] \definefloat [recipe] [figure] \setupfloat [recipe] [default={right,none}] \showframe \starttext \dorecurse{11}{\input ward} \placerecipe{}{\externalfigure[dum]} \stoptext
