Latest beta stops loading some ttc fonts
by Hongwen Qiu 26 Sep '14

26 Sep '14

The following minimal example used to work fine: \starttypescript [serif] [zhfonts] \definefontsynonym [Serif] [name:nsimsun] \stoptypescript \starttypescript [zhfonts] \definetypeface [zhfonts] [rm] [serif] [zhfonts] \stoptypescript \usetypescript [zhfonts] \setupbodyfont [zhfonts, rm, 11pt] \starttext 测试 \stoptext but it's no longer the case. The font used here is 'simsun.ttc' which ships with Chinese edition Windows systems by default. When I require "name:nsimsun" as above, the TTFAddLangStr() function in the luatex code base will have the following information: fontname lang NSimSun 0 NSimSun 1033 新宋体 2052 That is when lang equals 0 or 1033, the fontname will be NSimSun, but when lang equals 2052, the fontname will be 新宋体, the Chinese words for NSimSun. Although the ValidatePostScriptFontName() complains about the Chinese name of this font, and set 'bad_ps_fontname' to true, luatex itself don't stop the font fromgetting the right fontname NSimSun, since it chooses ASCII names when there're multiple fontnames. But actions["check metadata"](font-otf.lua, 1812)，sets the metadata.fontname from the correct "NSimSun" to "bad-fontname-simsun", and this change causes ff_get_ttc_index() to always return -1 as the index, which caused ConTeXt to complain about the following error message before bail out: (bad-fontname-simsun:-1)Invalid TTC index number mtx-context | fatal error: return code: 1 So, maybe font-otf.lua may need not change metadata.fontname and metadata.fullname if these two names are not nil?

Linetables
by Willi Egger 26 Sep '14

26 Sep '14

Good morning! I would like to use the line table environment. - In order to get started I copied the code from the wiki. After it did not work with the dorecurse commands I simplified the code to \starttext \setuplinetable[n=6,lines=40] \setuplinetable[c][1] [width=2cm,background=color,backgroundcolor=red] \setuplinetable[c][4] [width=3cm,background=color,backgroundcolor=yellow] \setuplinetable[c][6] [width=3cm,background=color,backgroundcolor=magenta] \setuplinetable[r][odd] [background=color,backgroundcolor=gray] \setuplinetable[r][even][background=color,backgroundcolor=green] \showframe \showstruts \setupcolors[state=start] \startlinetable \NC aaa\crlf aaa \NC bb \NC c \NC ddddd \NC eeee \NC ff} \NC \NR \stoplinetable \stoptext However with and without the dorecurse commands in it i get the following error: Missing number, treated as zero <to be read again> d \s!depth d-d epth \pack_black_rule_indeed ...\p_height \fi \s!depth \ifx \p_depth \v!max \stru... <argument> ...meter {x\c!depth }, \c!width =\wd \scratchbox ] \hskip -\wd \scratchbox \b... \firstoftwoarguments #1#2c-#1 \stoplinetablecell ...ox }\fi }{\box \scratchbox } \fi \egroup ... l.48 \NC aaa\crlf aaa \NC bb \NC c \NC ddddd \NC eeee \NC ff} \NC \NR 38 \setuplinetable[c][6] [width=3cm,background=color,backgroundcolor=magenta] 39 \setuplinetable[r][odd] [background=color,backgroundcolor=gray] 40 \setuplinetable[r][even][background=color,backgroundcolor=green] 41 42 43 \showframe \showstruts 44 45 \setupcolors[state=start] 46 47 \startlinetable 48 >> \NC aaa\crlf aaa \NC bb \NC c \NC ddddd \NC eeee \NC ff} \NC \NR 49 \stoplinetable 50 51 \stoptext I have no clue why is going wrong here… Thank you and kind regards Willi

new beta
by Hans Hagen 25 Sep '14

25 Sep '14

Hi, the first beta after the meeting: There are some changes to export and epub generation (will be explained in a manual). The most important is that there has been some improvements of the math export (esp fences and stackers). More will follow. The export now happens in a subpath. The epub generation is for 3.0 and has more options (like --purge, --svgmath and --rename). The svg math works quite ok (and is needed because it looks like only firefox will support mathml natively). The grid snapper has a few new methods, min, max and box that can be used in cases like \snaptogrid[min]\hbox{e.g. an image} The external figure mechanism has a new predefined conversion. One cna for instance say: \setupexternalfigures [order={pdf,eps,png,jpg}, conversion=cmyk.pdf, method=auto] We need it for projects where printing houses use over a decade old rips. There are probably some more things done but I already forgot about them.

Instruction required about hyphenation patterns
by Francisco Gracia 25 Sep '14

25 Sep '14

As well the original TeX manual as ConTeXt's one try to dissuade one of enquiring deeper into the subject of hyphenation patterns. For several reasons not to be explained at this moment this is however what I want to do. I have read all that I have found about the subject and think to have got a rather clear idea of the fundamental concepts. But I have been unable to understand how they are applied and can be managed in ConTeXt. So I would eagerly receive instruction about this question from someone who is competent enough in the field. As I understand that this is too involved a subject and of too little general interest for the mailing list, I suggest that any potential teacher sends me a private mail (fgragu023(a)gmail.com) I am ready to consider this as a consultorship or tutorship. Thanks in advance Francisco

parbuilder in lua
by Taco Hoekwater 25 Sep '14

25 Sep '14

Hi Hans, Can you please try the code below? I found three issues with it: 1. node-ltp.lua is not completely ready for nuts mode, e.g. line 3148: elseif order == 0 and hlist.list and last_badness > tex.hbadness then where ‘hlist.list' should be 'getfield(hlist, "list”)’ 2. with tracing on, I always get: Lua linebreak_filter failed, reverting to default on line 1 which makes me nervous. Does that mean it works ok without tracing, or does it just not report that it does not work? 3. with tracing on, there is a double-free of a glyph node (this could be specific to tufte) TIA, Taco Code: \tracingparagraphs=1 \tracingonline=1 \starttext \startparbuilder[basic] \input tufte \stopparbuilder \stoptext

Set: The Card Game
by Thangalin 25 Sep '14

25 Sep '14

Hi, Another ConTeXt example. https://bitbucket.org/djarvis/salish-card-set/src/ Included is a script (svg2mp.sh) that converts SVG files into MetaPost code. This allows for editing the image shapes in Inkscape (or similar) then manipulating them in MetaPost. This example code produces a thematic variation on Set. There are a few unsightly hacks, and some duplicated code that could be eliminated. Improvements and general comments are welcome.

math \prime with subscripts
by Yuri Teixeira 24 Sep '14

24 Sep '14

Hi is there a way for \prime not get smaller when used with sub/superscripts? Or realigned somehow? Without font changes would be nice. \starttext \startformula \frac13T\prime_{rs}T\prime_{st}T\prime_{tr} \stopformula \startformula \frac13T_{rs}\prime T_{st}\prime T_{tr}\prime \stopformula \stoptext Thanks YT

Thanks, Hraban, for your advice. I’ve no idea whether or not the error is connected with “too many open files”. The Project needs some 40 files but its working directory contains some 120 files (most of them only for testing purposes). Moreover, I usually only have the “project-file" open during processing (but I don’t know if that is important here). Surprisingly, as I wrote in my first post on this subject, the error up till now only occurs when I use interaction, and it usually does not occur anymore, at least on the same day, after I processed it once without interaction. But the next day, after sleep (of the Mac), the error may occur again. I did not change the settings but I will in case the problem gets worse. Best regards, Robert

Span all columns in natural tables
by Christoph Reller 23 Sep '14

23 Sep '14

Hi, Is it possible to define a cell that spans all columns without knowing beforehand how many columns there are? Specifically I would like to do something like this: \starttext \bTABLE \bTR \bTD[nc=<all>] I span all the columns \eTD \eTR \bTR \bTD col 1 \eTD \bTD col 2 \eTD <...> \bTD col n \eTD \eTR \eTABLE \stoptext Is there any expression for <all> that yields the total number of columns? I tried to use \tablecellcolumns but it is undefined if used at this location. Thank you for any feedback! Christoph Reller
