Par Builder Tests
by Keith McKay 05 Aug '23

05 Aug '23

Hi all, At the end of June, Hans uploaded a new lmtx version which included improvements to par building which he and Mikael had been working on in math mode. Hans suggested in the online chat that these improvements may be useful in typesetting novels. I was keen to try these since I have typset novels in the past. I have ran some tests on two novels which I downloaded from the Gutenberg Project site as epubs and extracted them to get the original xhtml files which I then typeset in context. I made very little in the way of changes to the files so that my setup for xml was very simple. Here are my setups for the layout of the novels showing some trackers that were used as well: \definepapersize[pagee][width=5.06in,height=7.81in] \setuppapersize[pagee] % XML setups here \startsetups[grid][mypenalties] \setdefaultpenalties \setpenalties\widowpenalties{1}{150} \setpenalties\clubpenalties {1}{150} \stopsetups \setuplayout[ width=10cm, topspace=0.5in, backspace=2.0cm, header=7.5mm, footer=0.25in, location={middle,middle}, vs=2, grid=yes, setups=mypenalties ] %\enabletrackers[makeup] %\enabletrackers[builders.hpack.quality] \enabletrackers[builders.hpack.overflow] %\enabletrackers[layout.vz] %\enabletrackers[paragraphs.passes] \enabletrackers[paragraphs.passes=summary] %\enabletrackers[paragraphs.passes=details] \setupalign[granular] %\setupalign[nothyphenated,hz,verytolerant] %\setupalign[vertical,height] %\setupalignpass[decent] %\setupalignpass[quality] %\setupalignpass[test1] \setupalignpass[test2] %\setupalignpass[test3] %\setupalignpass[test4] %\setupalignpass[test5] %\setupalignpass[optional1] %\setupalignpass[test2b] \starttext \setuppagenumbering[location={footer,middle},alternative=doublesided,state=start] \setcounter[userpage][1] %\showmakeup[vbox] %\showlayout \dostepwiserecurse{0}{30}{1}{ \xmlprocessfile{mysetups}{/path to xhtml files/4439720318703948998_84-h-\recurselevel.htm.xhtml}{} } \stoptext Below are the result showing the number of overfull boxes for these novels using the setups in the file spac-imp-tests.mkxl . See the manual Low Level - Lines Test Novel1 Novel2 Test1 70 35 Test2 30 8 Test3 62 23 Test4 89 40 Test5 28 9 Optional1 55 19 Quality 74 32 Decent 39 11 From these initial tests one can see that Test2 gave the lowest number of overfull boxes. So I edited test two, ran it, and the results are below. Test Novel1 Novel2 Test2b 11 0 My setup for test 2b is as follows: \startsetups align:pass:test2b \pretolerance 100 \tolerance 200 \parpasses 3 classes \indecentparpassclasses threshold 0.025pt tolerance 800 extrahyphenpenalty 50 next threshold 0.025pt tolerance 900 adjustspacing 3 adjustspacingstep 1 adjustspacingshrink 10 adjustspacingstretch 15 next threshold 0.025pt tolerance 1000 adjustspacing 3 adjustspacingstep 1 adjustspacingshrink 20 adjustspacingstretch 40 emergencystretch .25\bodyfontsize \relax % \linebreakpasses\plusone \stopsetups The only difference between test 2 and 2b are that I increased the tolerance in each of the three passes. In novel 2 this was successful in eliminating the overfull boxes but not in Novel 1 although I noticed that majority of overfull boxes were above 1pt with the largest about 12pt in Novel 1. I am at the stage now where I need some kind of strategy to reduce/eliminate overfull boxes, other than changing the tolerance, and I'm hoping for some advice from the community. Suggestions for further reading particularly on the commands in \setupalignpass and their usage would be appreciated and on the best way to tackle overfull boxes. Best Wishes Keith McKay

\defineactivecharacter in LMTX + composing characters
by Hamid,Idris 02 Aug '23

02 Aug '23

Dear gang, It appears that \defineactivecharacter does not work in lmtx: \starttext \defineactivecharacter Ḥ {\d{H}} \defineactivecharacter ḥ {\d{h}} \defineactivecharacter Ṣ {\d{S}} \defineactivecharacter ṣ {\d{s}} \stoptext This should not produce any typeset output but in lmtx it does. Background: The following characters are essential for Arabic transliteration (assuming your email client has the chars): Ṯṯ Ḥḥ Ḫḫ Ḏḏ Šš Ṣṣ Ḍḍ Ṭṭ Ẓẓ Ġġ Āā Īī Ūū ʿ ʾ But most really good fonts don't have them, so we have to compose them. Now there are other methods, e.g, 1) \definecharacter Hbottomdot {\buildtextbottomdot H} but cannot use it without something like \defineactivecharacter (there's no way we're going back to the bad old days of control sequences for accented chars). That is, we need to be able to say something like \definecharacter Ḥ {\buildtextbottomdot H} But this doesn't work. The other method 2) \definefontfeature[default][default][compose=yes] doesn't appear to work either (at least not with, e.g., Minion Pro Opticals). And even when it used to (somewhat) work (often ugly default results) it did not support utf 02BE and 02BF (ʿ ʾ). So we still need something like \defineactivecharacter ʿ {\high{c}} \defineactivecharacter ʾ {\kern.07 em \high{\rotate[rotation=180,location=high]{c}}} or better \definecharacter ʿ {\high{c}} \definecharacter ʾ {\kern.07 em \high{\rotate[rotation=180,location=high]{c}}} The upshot is that we need a general, configurable solution for this kind of situation. And please don't say, "Use a different font!" -) Thank you in advance for any guidance and assistance in this matter.

I had these lines in my header: ``` \setupcaptions[minwidth=0.95\textwidth, way=bychapter, prefixsegments=chapter] ``` In the new context, this seem to apply to all captions, while in the old context, it seems to apply only to those captions that are not specified otherwise.

OT: funny units

WRT to funny units consider this thread (in German): https://ruhrpott.social/@Matze/110812742577889798 Matze wrote: I read the 'as big as a song thrush' as a size and I find that we should set 'song thrush' as a standard unit for 20-22 cm. Text problem: Calculate how many square song thrush amount to a Saarland. (Saarland is the smallest federal country of Germany that is not only a city and often quoted for size comparison.) Magdalena calculated that with a given song thrush size of 20cm, one square song thrush is 400 cm² and a Saarland is about 64,250,000,000 square song thrush. ;) HR

Hi, here are three presentation styles for your amusement: https://codeberg.org/fiee/context-for-president I combined the code of my TUG, FrOSCon and CCCamp talks into kind-of a module. It’s still preliminary, comments are welcome. Thanks for all the help! Hraban

caption for moved sidefloat in the margin
by Henning Hraban Ramm 30 Jul '23

30 Jul '23

Hi again, I’m reading through the details manual and set up some figures as sidefloats that are offset to the margin. This works well. Now I’d like to have their captions in the margin, below the figure. If I set location=innermargin, then the caption is beside the image, i.e. somewhere at the edge. If I don’t, I can’t get it to move to the left edge of the image. How can I do that? Hraban """ \useMPlibrary[dum] \setuplayout[ backspace=5cm, width=12cm, ] \definefloat[marginfigure] \setupfloat[marginfigure][ leftmargindistance=-\leftmargintotal, rightmargindistance=-\rightmargintotal, default={inner,none,low,high}, ] \setupcaption[marginfigure][ style={\ss\tfx}, align={flushleft}, width=\leftmarginwidth, %location={innermargin,low}, ] \starttext \showframe \startplacemarginfigure[ location={inner,3*hang}, title={My caption should be flushleft and aligned with the image.}, ] \externalfigure[dummy][width=.66\textwidth] \stopplacemarginfigure \samplefile{lorem} \stoptext """

issue with current latest (2023.07.28 20:04)

Dear list, trying to generate the format for current latest (2023.07.28 20:04), I get this error message: tex error > tex error on line 280 in file lang-lab.mkxl: Control sequence expected instead of undefined \lang_labels_define_class_indeed {head}{ <macro> \definelabelclass ...ded {\lang_labels_define_class_indeed {#1}{\ifchknumber #2\or \lastchknumber \else \zerocount \fi }\expandafter \noexpand \csn ... <line 3.280> \definelabelclass [head] [0] % titles <empty file> You injected something that confused the parser, maybe by using some Lua call. LuaMetaTeX is from 20230727 (just in case it might be relevant). Could anyone confirm the issue? Many thanks for your help, Pablo
