\mainlanguage[pe]
by Mohammad Hossein Bateni 01 Aug '16

01 Aug '16

Hello, This was lost in the other thread, so I'm starting a fresh one dedicated to the question. 1) \showinstalledlanguages does not show pe/persian/fa or anything like that but it has several arabic variants. was this dropped in MkIV or was there never a persian language environment even in MkII? I thought there were translated labels for Farsi somewhere. 2) In the following MWE, ad-hoc hyphenation using \- works and leads to hyphenation. However, specifying the pattern at the beginning does not have any effect. Am I missing something? \usemodule[simplefonts] \setmainfont[dejavusans][features=arabic,range=arabic] \setupalign[r2l] \showframe \hyphenation{سازمان‌-دهی} \starttext %% The above pattern is not used here and the long word moves into the margin. \dorecurse{14}{سلام } سازمان‌دهی مناسب. %% It does work here, though. \dorecurse{14}{سلام } سازمان\-دهی مناسب. \stoptext How can one create a new language? The languages manual <http://www.pragma-ade.nl/general/manuals/languages-mkiv.pdf> suggests that this is possible. Does that mean I need to send the request to Hans/Wolfgang to create the new entry or can one do so dynamically? Beside the issue of sorting in indices, etc.—which I will get to in due time—having an entry for language pe/persian seems to be necessary to *properly* use \setuplabeltext, etc. Is that correct? Thanks a lot! —MHB

Math columns in Natural Tables
by Henri Menke 01 Aug '16

01 Aug '16

Dear list, with the old tabulate macros there was the possibility to format columns as math (m for inline, M for display). Is there any possibility to typeset cells in math mode in Natural Tables? This way, the hyphen would be rendered as minus and spacing around relation and binary operators would be consistent (example below). Cheers, Henri --- \starttext \starttabulate[|m|] \NC -4.11\%<0.02\% \NC\NR \stoptabulate %\setupTABLE[???] \startTABLE \NC -4.11\%<0.02\% \NC\NR \stopTABLE \stoptext

Hyphenation errors (again or still) in recent mkiv
by Robert Blackstone 01 Aug '16

01 Aug '16

Dear all, In the setupfile of my project I have \mainlanguage[en]. The font used is Verdana. With mkiv versions till october 2015 the hyphenation of English words was always correct. The same files compiled with mkiv of july 2016 (version 2016.07.18 16;26) give hyphenations that are definitely wrong. Some examples: begi-nning, pr-ocedure, adequ-ately, st-yle I made some tests with Linux Libertine sans and here also the earlier mkiv's gave correct hyphenations, the july version wrong ones. So it seems that ref. hyphenation something is wrong with this mkiv-version. Or do I now have to use something other than \mainlanguage[en] ? BTW, I found a similar discussion on this list at the beginning of february. Apparently the problem either was not solved or has returned. Thanks in advance for advice. Best regards, Robert Blackstone

Randomize control points in metapost/metafun?
by Mikael P. Sundqvist 01 Aug '16

01 Aug '16

Hi! I look for a way to randomize control points of a path, leaving the coordinates themselves untouched. The reason is the following: I want to draw (for example) a circle with a triangle inside, and I want them to look slightly randomized. If I do (see attached pdf for a typical result of this) \startMPpage draw fullcircle scaled 2cm randomized 0.1cm; draw ((1cm,0)--(0,1cm)--(-1cm,0)--cycle) randomized 0.1cm; \stopMPpage then the corners of the triangle does not stay on the circle (and I want them to). [I dont want the triangle to consist of perfectly straight lines, so I cannot (directly) draw the triangle using different points along the randomized circle] I imagine that one could achieve what I want if one could randomize the control points only. Also, is it possible to randomize a picture (consisting of several paths/points) somehow, without randomizing each part of it manually? /Mikael

Hi Hans, I'm afraid I'm lost here. When I copy what you write you get and paste it into my example I still get, with Verdana 10 pt, no hyphenation errors with mkiv version 2015.10.09 21:28 and some with mkiv version 2016.07.18 16:46: marv-elous and di-scriminate. So doesn't it show that at least the two mkiv-versions differ in this respect and that when using the new version something extra or different has to be done in the setups to get the correct hyphenations? Fortunately I still have kept some of the older ConTeXt-versions, so my project will not suffer from hyphenation error. But I suspect that reliance on older versions should not have to be necessary. Best regards, Robert Blackstone

gmane might go off-line soon
by Schmitz Thomas A. 01 Aug '16

01 Aug '16

Hi all (especially the gardeners), have you seen this post? https://lars.ingebrigtsen.no/2016/07/28/the-end-of-gmane/ Long story short: the sole maintainer of gmane is getting fed up with ddos attacks and is thinking about terminating the service. If I’m not mistaken, for the time being, gmane is the only searchable archive of the context mailing list, so this would be a major setback. On the garden, there has been a note for five or six years (I think) that work is being done on archive.contextgarden.net. Maybe the approaching end of gmane would be a good motivation to really do this work? Thomas

lua tables - how do you cope?
by Schmitz Thomas A. 31 Jul '16

31 Jul '16

This is less a specific question about ConTeXt than a hope for good advice: I’m maltreating my xml files with a mixture of TeX and Lua. I want to extract and typeset information in different forms, so I first collect everything in lua tables, rearrange and order these tables and typeset the results. All fine and dandy. My problem is that I have to have tables within tables within tables… you get the picture. One aspect of Lua that is really bugging me is the fact that associative tables have no order, which can be a pain in the butt for this kind of operation. So I have to be careful that I have to use constructs that will keep the order in which items have been added and loop through them via ipairs() instead of pairs(). I find it difficult to keep track of what’s inside my layers upon layers of tables. So my question is: how do those of you who are more experienced with this kind of question proceed? Do you have any handy tool to visualize a table? Any tips you want to share? Thanks a lot! Thomas

inconsistent math fontsize
by Jan Willem Flamma 30 Jul '16

30 Jul '16

Dear list members Sofar, I’ve been using \qquad to separate two formulas side-by-side on a single line. To ensure consistency with spacing I want to change to using a \startformulas .. \stopformulas construction. See MWE below However, the solution using the \startformulas .. \stopformulas construction gives a noticeably smaller fontsize ! I’m using the latest beta: ConTeXt ver: 2016.07.25; Luatex 0.95 Worth noting that all both fontsizes are identical when using context live via contextgarden. Kind regards, Jan Willem Flamma MWE: \starttext % Printed in normal fontsize \startformula a=\frac{b}{c} \qquad \qquad \qquad a=\frac{b}{c} \stopformula % Printed in smaller fontsize \startformulas \startformula a=\frac{b}{c} \stopformula \startformula a=\frac{b}{c} \stopformula \stopformulas \stoptext

(perhaps benign) difference in ebgaramond12-regular.tma after upgrade to 2016.07.30 00:26 beta
by Joseph Canedo 30 Jul '16

30 Jul '16

Hi Hans, Perhaps completely benign, but a bit strange difference I’ve spotted (because I log the ligatures of the font I use). After upgrade to 2016.07.30 00:26 I notice that 1 entry (only one which is a bit strange, because there are other similar entries in the description table which were not changed at all) in descriptions table in ebgaramond12-regular.tma (in tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/fonts/otl/ directory) has changed from [983766]={ ["boundingbox"]=519, ["index"]=2684, ["name"]="ij.sc", ["unicode"]={ 105, 106 }, ["width"]=570, }, To (latest beta) [983766]={ ["boundingbox"]=519, ["index"]=2684, ["name"]="ij.sc", ["unicode"]=307, -- 307 is ij ligature whose unicode = { 105, 106 } ["width"]=570, }, Is this expected at all ? Thanks a lot Best regards Joseph Canedo
