Bug in Luatex file handling?
by Hans van der Meer 15 Jun '21

15 Jun '21

This I cannot explain. Opening a file directly from its full name in a string succeeds. But doing the same from a parameter transferred from ConteXt to Lua succeeds if the file is in one directory deeper but fails if the file is two directories deeper. I suspect there is something not ok in LuaTeX. The lines with .... and >>>> directly come from print statements inserted in the Lua code. dr. Hans van der Meer Open file in directory 1 and 2 levels deep - direct call succeeds ..........io.open("events/hga-0372-345-62.xml","r")=>file (0x7fff97415f88) ..........io.open("events/transcripten/hga-0372-345-62.xml","r")=>file (0x7fff97416020) Idem but now from parameter filename transferred from ConTeXt into Lua: Open file one level deeper succeeds (printed filename comes from the call): >>>>>>>>>>io.open(filename,"r") filename=events/hga-0372-1764-63.xml=>file (0x7fff974160b8) Open file two levels deeper fails: >>>>>>>>>>io.open(filename,"r") filename=events/transcripten/hga-0372-1764-63.xml=>nil Caller: \def\FileExist#1{\cldcontext{hvdm.existfile([===[#1]===])}} Lua code: hvdm.existfile = function (filename) -- The test code was inserted here -- local file = io.open(filename, "r") if file then file:close() end return file ~= nil and "true" or "false" end

Trouble with using predefined typescript files
by mastermind_ x 15 Jun '21

15 Jun '21

Hello everyone, I am reading the ConTexT manual’s chapter on Typography. I want to achieve a Palatino-like small font which is bolder than the default provided by ConTeXt like in some math textbooks. So I loaded the typescript files ie type-xxx stated in the chapter in turns no matter the type-xxx I load. I always got this in the log: fonts > typescripts > unknown library 'xtx' fonts > typescripts > unknown library 'gyr' selectfont > the requested font 'palatino' has no files for the 'tf' alternative, Latin Modern is used instead. selectfont > the requested font 'palatino' has no files for the 'tf' alternative, Latin Modern is used instead. selectfont > the requested font 'palatino' has no files for the 'tf' alternative, Latin Modern is used instead. selectfont > the requested font 'palatino' has no files for the 'tf' alternative, Latin Modern is used instead. \usetypescriptfile[type-xtx] \usetypescriptfile[type-gyr] \usetypescript[palatino][ec] \definefontfamily [mainface] [rm] [palatino] \definefontfamily [mainface] [ss] [palatino] \definefontfamily [mainface] [mm] [palatino] \definefontfamily [mainface] [tt] [palatino] \setupbodyfont[mainface,11pt] \starttext Hello world! \stoptext What am I missing? Are these not available right from the box like the book said? These are ‘predefined typescripts’ as the book said after all. Thanks. I use MacOS if that helps current version of ConTeXt: 2021.03.05 19:11 ~Jethro

Hi, A few things (1) Thomas and I picked up the facing floats thread. I will probably remove the experimental code from mkiv and only work on the lmtx implementation. The same can be true for streams. (2) The \limits and \nolimist etc commands are actually modifiers and so are \Umathadapttoright and \Umathadapttoleft. Because we have a couple of 'handy' options in several math constructs in the engine I decided to add a few more modifiers to (ab)use those features too. The next examples are for 'math detail lovers': % \displaylimits % \limits % \nolimits % \ordlimits (maybe replace that one now or maybe no longer needed anyway) % \Umathadapttoleft % \Umathadapttoright % \Umathaxis % \Umathnoaxis % \Umathphantom % \Umathvoid % \Umathopenupheight <dimension> % \Umathopenupdepth <dimension> % \Umathlimits % \Umathnolimits \startTEXpage[offset=5mm] \startformula x = \integral^1_2 \mathinner{\vrule height 10mm depth 10mm width 5mm} = x = \integral^1_2 \mathinner{\vrule height 20mm depth 20mm width 5mm} = x = \integral^1_2 \mathinner{\vrule height 30mm depth 30mm width 5mm} = x = \integral^1_2 \mathinner{x} = x = \integral^1_2 x \stopformula \stopTEXpage \startTEXpage[offset=5mm] $ x = \integral^1_2 \mathinner{\vrule height 10mm depth 10mm width 5mm} = x = \integral^1_2 \mathinner{\vrule height 20mm depth 20mm width 5mm} = x = \integral^1_2 \mathinner{\vrule height 30mm depth 30mm width 5mm} = x = \integral^1_2 x = $ \stopTEXpage \def\rab {\Umathchar"1"00"007C } \def\lrab{\Umathchar"4"00"007C } \def\rrab{\Umathchar"5"00"007C } % \Umathmodifier : plus\minus \definecolor[mtestcolor][a=1,t=.5,s=.5] \startTEXpage[offset=5mm] $ \color[green]{\rab\Umathadapttoright^{\black 1}_{\black 2}^^3__4} \color[blue] {\mathinner{\vrule height 30mm depth 30mm width 5mm}} \color[red] {\rab\Umathadapttoleft ^5_6^^{\black 7}__{\black 8}} $ \quad $ \rab\Umathadapttoright^1_2^^3__4 \mathinner{\vrule height 30mm depth 30mm width 5mm} \rab\Umathadapttoleft^5_6^^7__8 $ \quad $ \showboxes \rab\Umathadapttoright\Umathnoaxis^1_2^^3__4 \mathinner{\vrule height 30mm depth 30mm width 5mm} \rab\Umathadapttoleft\Umathnoaxis^5_6^^7__8 $ \quad $ \showboxes \rab\Umathadapttoright\Umathnoaxis\Umathphantom^1_2^^3__4 \mathinner{\vrule height 30mm depth 30mm width 5mm} \rab\Umathadapttoleft\Umathnoaxis\Umathphantom^5_6^^7__8 $ \quad $ \showboxes \rab\Umathadapttoright\Umathnoaxis\Umathvoid^1_2^^3__4 \mathinner{\vrule height 30mm depth 30mm width 5mm} \rab\Umathadapttoleft\Umathnoaxis\Umathvoid^5_6^^7__8 $ \quad $ \showboxes \rab\Umathadapttoright\Umathnoaxis\Umathvoid\Umathopenupheight5mm^1_2^^3__4 \mathinner{\vrule height 30mm depth 30mm width 5mm} \rab\Umathadapttoleft \Umathnoaxis\Umathvoid\Umathopenupdepth 5mm^5_6^^7__8 $ \stopTEXpage \startTEXpage[offset=5mm] $ \showmakeup[math] \rab\Umathadapttoright\Umathnoaxis\Umathopenupheight 5mm^1_2^^3__4 \mathinner{\mtestcolor\vrule height 10mm depth 10mm width 5mm} \rab\Umathadapttoleft \Umathnoaxis\Umathopenupdepth 5mm^5_6^^7__8 $ \quad $ \showmakeup[math] \openinnerspacing \textstyle 5mu \innerclosespacing\textstyle 5mu \lrab\Umathadapttoright\Umathnoaxis\Umathopenupheight 5mm^1_2^^3__4 \mathinner{\mtestcolor\vrule height 10mm depth 10mm width 5mm} \rrab\Umathadapttoleft \Umathnoaxis\Umathopenupdepth 5mm^5_6^^7__8 $ \quad $ \showmakeup[math] \openinnerspacing \textstyle 5mu \innerclosespacing\textstyle 5mu \lrab\Umathnolimits\Umathadapttoright\Umathnoaxis\Umathopenupheight 5mm^1_2^^3__4 \mathinner{\mtestcolor\vrule height 10mm depth 10mm width 5mm} \rrab\Umathlimits \Umathadapttoleft \Umathnoaxis\Umathopenupdepth 5mm^5_6^^7__8 $ \stopTEXpage \startTEXpage[offset=5mm] $ \showmakeup[math] \frozen\openinnerspacing \textstyle 10mu \frozen\innerclosespacing\textstyle 10mu \lrab\Umathnolimits\Umathadapttoright\Umathnoaxis^1_2^^3__4 \mathinner{\mtestcolor\vrule height 10mm depth 10mm width 5mm} \rrab\Umathlimits \Umathadapttoleft \Umathnoaxis^5_6^^7__8 = \frozen\openinnerspacing \textstyle 2mu \frozen\innerclosespacing\textstyle 2mu \lrab\Umathnolimits\Umathadapttoright\Umathnoaxis^1_2^^3__4 \mathinner{\mtestcolor\vrule height 10mm depth 10mm width 5mm} \rrab\Umathlimits \Umathadapttoleft \Umathnoaxis^5_6^^7__8 $ \stopTEXpage \stoptext I'm still wondering about some interfacing but that depends on it being used (at all) but at least we can finetune a bit more abstract if we want to.

dictionary example
by jbf 13 Jun '21

13 Jun '21

I am wondering if someone has tried a two-column dictionary layout with ConTeXt. What is confounding me at the moment is the gap between entries in the columns. My MWE is below. Try as I may, I seem unable to get rid of those gaps! I obviously want each entry to follow on from the other. I'm obviously not doing things right! If someone has already set up a dictionary and has a model they could share I'd be grateful. I'm attaching a screenshot of the result from the code below.

upload / some new math stuff
by Hans Hagen 11 Jun '21

11 Jun '21

Hi, I played a bit with these newcomputermodern fonts. They are extended versions of latin modern and come in: - 10pt (serif, sane, mono, math) - book (serif, sane, mono, math) - 8pt (partial) I made a typescript for the 10pt regular and book (as I see no reason to configure 8pt). So, assuming that one installs these fonts: \setupbodyfont[newcomputermodern-book] \setupbodyfont[newcomputermodern] should work ok. The book variant is quite nice. I didn't look into the provided math alternates (context supports that but I didn't define them for this font ... input from math lovers is welcome). Now, this font also implements, as cambria does, upright integrals and as that has comes on my radar every year when I ponder these integrals I decided that it was about tiem to deal with it properly. It is no big deal to implement them gropwing (after all one can see them as left delimiter) but the main issue are these super and subscripts. \setupbodyfont[newcomputermodern-book] % \setupbodyfont[cambria] \starttext \startformula x = \integral^1_2 \mathinner{\vrule height 10mm depth 10mm width 5mm} = x = \integral^1_2 \mathinner{\vrule height 20mm depth 20mm width 5mm} = x = \integral^1_2 \mathinner{\vrule height 30mm depth 30mm width 5mm} = x = \integral^1_2 \mathinner{x} = x = \integral^1_2 x \stopformula \startformula x = \int\Umathadaptsize^1_2 \mathinner{\vrule height 10mm depth 10mm width 5mm} = x = \int\Umathadaptsize^1_2 \mathinner{\vrule height 20mm depth 20mm width 5mm} = x = \int\Umathadaptsize^1_2 \mathinner{\vrule height 30mm depth 30mm width 5mm} = x = \int\Umathadaptsize^1_2 \mathinner{x} = x = \int\Umathadaptsize^1_2 x \stopformula \def\rab{\Umathchar"1"00"007C } $ x = \int\Umathadaptsize^1_2 \mathinner{\vrule height 10mm depth 10mm width 5mm} = x = \int\Umathadaptsize^1_2 \mathinner{\vrule height 20mm depth 20mm width 5mm} = x = \int\Umathadaptsize^1_2 \mathinner{\vrule height 30mm depth 30mm width 5mm} = x = \int\Umathadaptsize^1_2 x = x = \rab\Umathadaptsize^1_2^^1__2 \mathinner{\vrule height 30mm depth 30mm width 5mm} $ \stoptext After playing with several solutions (delimiters, fences, radicals etc) I just settled for a few line extension to the engine (there was already plenty in place in luametatex for that anyway) and it seem to work ok. This \Umathadaptsize is a bit like the limits related suffixes (and uses the same scanner logic). It basically flags an operator as something that should grow cf what follows. I can add some fine tuning if needed (can also be dealt with at the macro end, as with other mechanisms, but this is just a first test of useability). (I might also extend another mechanism to deal with it but putting scripts on top or after is already handles pretty well by regular mechanisms, so ...) Of course only a few fonts provide these upright growing integrals (makes me wonder about summation and product). Concerning the newcm fonts: for some reason the book variants (otf files) are about twice as large (in filesize) but what we use (cached) is the same size (only bboxes differ) so there is something fishy in the otf. I can imagine that at some point we add the 10pt/book ones to the standard mkiv distribution and maybe only the subset to the lmtx distribution but for now these book ones are too big for that, but it all depende on them being used. Happy testing (hopefully there are no side effects).

Incorrect sorting in \completelistofabbreviations for numbers

Hi everyone, I think I've found a sorting bug in \completelistofabbreviations in the latest LMTX (and probably also MKIV). When using this minimal example \abbreviation[OTT]{123}{One, Two, and Three} \abbreviation{ABC}{A, B, and C} \abbreviation{ZYX}{Z, Y, and X} \starttext \completelistofabbreviations[criterium=all] \stoptext I get ABC A, B, and C 123 One, Two, and Three ZYX Z, Y, and X Numbers should go before letters. Do you know any workaround/fix for that? Best, Markus
