Size of fences, factor key
by Mikael P. Sundqvist 26 Apr '18

26 Apr '18

Dear Hans and others, I'm usually use the \big, \Big, \bigg etc to get the size of parentheses, brackets and braces to be the size I want. I realize that the fences machinery is probably a cleaner way of doing this. I tried it a bit, and it usually gives the result I like. But sometimes not, and it seems that the way to change the size of the parentheses/brackets/braces is to use the factor key. 1) Are the different options none, auto NUMBER explained somehere? 2) Could one have, for exceptional cases where the default is not satisfactory, a keyword like factor=big for example, to get the same size as if one would have used \big? I am a bit confused. See the example below, with output (from latest standalone) attached. /Mikael PS: I would suggest to have italic = { feature = 'ss01', value = 1, comment = "Mathematical Alternative Lowercase Italic" }, set in lucida-opentype-math.lfg. In all books (on math) I have seen, I think this is what is used. %%% Example file: \setupbodyfont[lucidaot] \definemathfence[Set][left="007B,right="007D,command=yes] \startbuffer \startformula \Set{x\in\mathbb R~:~x^2=1} \stopformula \stopbuffer \startTEXpage[offset=3bp] \startformula \{x\in\mathbb R~:~ x^2=1\}%Too small \stopformula \startformula \bigl\{x\in\mathbb R~:~ x^2=1\bigr\}%I like this one \stopformula \startformula \Bigl\{x\in\mathbb R~:~ x^2=1\Bigr\}%Too big \stopformula \getbuffer \setupmathfence[Set][factor=1]%I like this one \getbuffer \setupmathfence[Set][factor=auto]%Too big \getbuffer %\setupmathfence[Set][factor=big]%Perhaps this could work?

path for luatex cache
by Peter Münster 25 Apr '18

Hi, What should I do please, to prevent ConTeXt from creating $HOME/luatex-cache? I tried: - TEXMFCACHE=/opt/context/tex/texmf-cache - TEXMFVAR=/opt/context/tex/texmf-cache - LUATEX_CACHE=/opt/context/tex/texmf-cache/luatex-cache but without success... TIA for any help, -- Peter

doiffile
by Hans van der Meer 25 Apr '18

25 Apr '18

The \doiffile macros recognize the existence of a file but, unless I am mistaken, not the existence of a directory. Is there another macro, whose existence I have nof found yet, that offers this capability? Or should this be a slight encouragement to expand the implementation in that direction? dr.

Question to sectioning
by Tomas Hala 25 Apr '18

25 Apr '18

Hello, I have got a document with e.g. six chapters, numbers are from 1 to 6. At special places I would like put a special page containing a special title. The special page should be without a header and without any number, the title should be put into the contents by the same way as other chapters.. I came across two problems: First, in the minimal example below I get chapter numbers 1, 2, 4, 5, 7, 8 and if I use incrementnumber=no, the "specialpage" is not stored in the contents. Secondly, I do know how to switch off the header only at this special page. I also tried \definehead[specialpage][title] but in this case the "specialpage" is not stored in the contents, too. What I am doing wrong? Thanks for the help in advance, Tomáš % TL2017 \definehead[specialpage][chapter] \definehead[levelA][chapter] \setuphead[specialpage][number=no] %,incrementnumber=no] \starttext \definecombinedlist[mycontent][levelA,specialpage][level=chapter] \completemycontent \levelA{A1} \levelA{A2} \specialpage{Special page 1} \levelA{A3} \levelA{A4} \specialpage{Special page 2} \levelA{A5} \levelA{A6} \stoptext

Dear list members, I do not know when this problem first appeared, I have not used the units package for a while, but merely invoking the package with the latest beta provokes an error. MWE: \usemodule[units] \starttext help \stoptext The attached log says there is a problem on line 42 of m-units.mkiv. Any help would be appreciated. -- With kind regards, Michael Guravage

Installing a specific version of context
by N. Raghavendra 24 Apr '18

24 Apr '18

I would like to install the version of context dated 2017.11.14. How can one do this? I tried sh first-setup.sh --context=2017.11.14 but it produces errors like rsync: change_dir "/current/context/2017.11.14" (in minimals) failed: No such file or directory (2) I'd appreciate suggestions about this. Thanks, Raghu. -- N. Raghavendra <raghu(a)hri.res.in>, http://www.retrotexts.net/ Harish-Chandra Research Institute, http://www.hri.res.in/

xmlpos not enough for me
by Hans van der Meer 24 Apr '18

24 Apr '18

The macro \xmlpos{#1} returns the position number of the current node in its parent. However, I would like to know the position number in its parent for the node with the same tag. An example of what I mean: <parent> <somenode></somenode > <node>inside it \xmlpos{#1} will return 2 but I would like 1> <somenode></somenode > <somenode></somenode > <node>inside it \xmlpos{#1} will return 5 but I would like 2> </parent> Can this be accomplished already or does it require a new API? dr.

Reproducible PDF output not working
by N. Raghavendra 24 Apr '18

24 Apr '18

Sometime ago, I asked here about reproducible PDF output, and was told about the --nodates option of context. It worked then, but doesn't seem to be working now, with a recent version of context. ---------------------------------------------------------------------- $ cat foo.tex \starttext Hello, world! \stoptext $ ( rm -f a b foo.log foo.pdf foo.tuc && \ context --nodates foo.tex && cp foo.pdf a && \ sleep 1 && \ context --nodates foo.tex && cp foo.pdf b ) > /dev/null && \ md5sum a b bdd1911005623a519f5ecb3dbcb8bc7b a 06157e2840c0758ca46d5e7f0be239ef b $ context --version [elided] mtx-context | current version: 2018.04.19 15:53 ---------------------------------------------------------------------- File `a' has the words "<pdfx:ID>foo.2018-04-24T01:49:47-19:00</pdfx:ID>", and file `b' has "<pdfx:ID>foo.2018-04-24T01:49:49-19:00</pdfx:ID>" at the corresponding position. Please tell me how to ensure that the PDF output depends only on the source, and not on the time the output is generated. Thanks, Raghu. -- N.

Question about paragraphs and hanging punctuation
by Tomas Hala 24 Apr '18

24 Apr '18

Hi all, I used together hanging punctuation and define/setup paragraphs (tested on TL2017, current CTX). Unfortunately, inside the paragraph environment the hanging punctuation settings is ignored. Moreover, it seems that attributes inner= and command= works only for the first paragraph (column). The only one way I discovered is to write manually \setupalign[hz,hanging] command at the beginning of each column which is not very comfortable. I would like to ask you whether is here some way to set it generally. Or (better) to inherited it from the outer settings. Thanks in advance, Tomáš ------ Minimal example: \definefontfeature[default][default][protrusion=quality,expansion=quality] \starttext\mainlanguage[cz] \defineparagraphs[pokus][n=2] \setupparagraphs[pokus][1][width=10cc] %\setupparagraphs[pokus][1][width=10cc,inner={\setupalign[hz,hanging]}] % command=... \setupalign[hz,hanging] \setupbodyfont[modern,12dd] text \startsomepars text \nextsomepars text \stopsomepars text \stoptext

Characters allowed in macro names
by N. Raghavendra 22 Apr '18

22 Apr '18

I was wondering if it is alright to use underscores in the names of macros, e.g, as in the following file. It looks like \startsetups, and \def accept names with hyphens, underscores, and numerals, but \starttexdefinition doesn't tolerate any of them. 1. In general, what characters are allowed in macro names? Are Unicode characters admissible? 2. Apart from the fact that one can use whitespace freely in \starttexdefinition, is there any reason to prefer it over \def? Thanks, Raghu. ------------------------------------------------------------ \starttext \startsetups [hello-world_1] Hello, world 1! \stopsetups \setups [hello-world_1] \def\hello-world_2{Hello, world 2!} \hello-world_2 \starttexdefinition helloWorld Hello, world! \stoptexdefinition \helloWorld %% Doesn't work %% \starttexdefinition fooBar1 %% Foo, bar 1! %% \stoptexdefinition %% %% \fooBar1 %% Doesn't work %% \starttexdefinition foo_bar %% Foo, bar! %% \stoptexdefinition %% %% \foo_bar %% Doesn't work %% \starttexdefinition foo-bar %% Foo, bar! %% \stoptexdefinition %% %% \foo-bar \stoptext ------------------------------------------------------------ -- N.
