Numbers in Tables
by Bart Wise 30 Jan '08

30 Jan '08

The code below defines a number and then on each row, displays then increments the number. The number is defined and reset to 0 before the table is declared. However, when the number is displayed in the table, it's not zero as expected, but some other number (usually between 3 and 9). The reset at reset point #1 does reset the number to 0, but it doesn't stay that way when the table is declared. The only thing I have found to work, is to define a row and column and put the reset there (see reset point #2). I would like to declare and reset the number outside of the table definition, but it doesn't seem to work. What am I doing wrong? \definenumber[MyNum] \starttext \resetnumber[MyNum] % reset point #1 \bTABLE % \bTR\bTD \resetnumber[MyNum] \eTD\eTR % reset point #2 \bTR\bTD \getnumber[MyNum]\incrementnumber[MyNum] \eTD\eTR \bTR\bTD \getnumber[MyNum]\incrementnumber[MyNum] \eTD\eTR \bTR\bTD \getnumber[MyNum]\incrementnumber[MyNum] \eTD\eTR \bTR\bTD \getnumber[MyNum]\incrementnumber[MyNum] \eTD\eTR \eTABLE \stoptext

Hi, i uploaded a fix for the reported problems; the uploaded version also uses lua for locating files that have to be included; this should work with the mkiv xml too (i forgot who asked for that but i needed it myself too) -- ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

MKIV Chinese typesetting
by Yue Wang 29 Jan '08

29 Jan '08

Dear Hans and other friends: I play a little bit on MKIV's Chinese support and find it is incomplete. It has some serious problems, and lack important features as well. Well, I know it from mk.pdf that Chinese support is under construction, so in this email I just want to give some Chinese horizontal typesetting suggestions for development (vertical typesetting are more frequently used in Hongkong, Taiwan and Japan, so maybe people from there are eager to help): first, a features many Chinese people like: a lot of Chinese users write essays using full-width punct (that is, a punct mark is as the same size as the Chinese characters) and I found that the puncts are compressed well in context with good penalty settings(although there are minor problems in the pdf). however, sometimes it is up to the publisher which kind of punct marks are to be used, and usually many scientific books and papers use half-width puncts. so I think a new feature should be added to map all the Chinese puncts into english while at the same time, a space should be added after the English punct marks. that is, changing 中文，中文 into 中文, 中文 notice the space in the second example there is an opentype feature called hwid, but it should not be used because: - it changes the English alphabets as well - most of the time the function in most Chinese fonts is missing or buggy - it does not automatically add the space These are the minor problems in the mk.pdf: - pp118, penultimate example, box 2, line1, the ' punct mark should not appear at the end of the line - pp118, ultimate example, box 2, line2, in fact, if you want do perfect Chinese typesetting, all the puncts which begin a line or end a line should be closed to the margin line which makes the type block look good (especially when watch the right or left edge of the type block closely) while this ' has many space before it. In English, it is quite easy and the good old tex does a good job because all the letters and puncts are designed carefully, but in Chinese things are much difficult because all the glyphs including the puncts in all the Chinese fonts have the same width, and which makes the problem worse is that different Chinese fonts have different positions for these puncts. So a dynamic way which calculates the most left edge and most right edge of a punct glyph should be used, and it is not available in luatex:( will it be added later? second, and the most important, on the bilingual typesetting: nowadays English words are frequently used in Chinese, so great care must be taken to handle it. many Chinese users write their manuscript in one of the two ways: 中文 English 中文 or 中文English中文 The first way looks good when using a editor with mono space font and the second way is convenient for one to type. So both users will happy if both ways get the same result in context. in MKII, users are forced to use such kind of expression which drives them crazy and should be avoided: 中文English\ 中文 A small skip should be left between Chinese and English which makes the result much better. usually the space is a quarter of a chinese character width. A TeX expression should like: \hspace{0.25em plus 0.125em minus 0.08em} but I think it is better to introduce a \setupxxxwidth for the user. The last important thing for English and Chinese bi-lingual typesetting is that: do not use English glyphs in Chinese fonts because: - recently English glyphs in most of the Chinese fonts are ugly - users have no right to modify the Chinese fonts - many other reasons so when set up a Chinese typeface, it is better to leave a feature for the user to choose the accompany english typeface. while typesetting, Chinese typography rules do not interfere with the english one, that is, chinese part and english part use their own line break model. here are two bugs in recent context: - 中文 English English English 中文will produce 中文EnglishEnglishEnglish中文, the spaces between english words are all missing. - the following script produce an error: Invalid field id penalty for node type glyph (1). Here is a sample: \definefontfeature[chinese][mode=node,script=hang,lang=zht,script=hani,lang=dlft] \definefontsynonym[songti][name:AdobeSongStd-Light][features=Chinese] \definefontsynonym[Serif][songti] definetypeface[song][rm][serif][songti] \setupbodyfont[song,12pt,rm] \starttext 中文 English: 中文 \stoptext third, indenting: Chinese paragraphs are indented with two Chinese characters, and we also indent the first paragraph. context is so powerful that it is easy to do these kind of things, thank you:) and i think it is better to write it into the Chinese typesetting module? Urgency: bi-lingual typesetting > fix the wrong panelty > map the english punct maps as an alternative > indenting > puncts should be close to margin lines. I am eager to see full support for chinese and other Asian languages (and I am eager to help too), and i hope my suggestions here are helpful to the developers. I am grateful to Hans, Taco and and many other guys (eg. Zhichu Chen) that did a very good job in recent MKIV Chinese support. Thank you for your time and effort for continuous contributions!

the new minimal is broken
by Yue Wang 28 Jan '08

28 Jan '08

Hi, I see the Jan 26 version of context so I just want to upgrade my system. As what I did before, go to http://minimals.contextgarden.net/ and download the file, unzip it and run. after rsync, it cannot generate the mkiv format (other formats are fine) I run Debian on x86 intel machine. I had done this several times in the past month and everything is fine. btw, why is download speed so slow these days? after hours of rsync it finally began to generate the format.... here is the message. yulewang@yulewang-laptop:~$ luatools --generate LuaTools | skipping /home/yulewang/tex/texmf-local/web2c/texmf.cnf LuaTools | skipping /home/yulewang/tex/texmfcontext/web2c/texmf.cnf LuaTools | loading /home/yulewang/tex/texmf/web2c/texmf.cnf LuaTools | preparing configuration in ///home/yulewang/tex/texmf-cache/luatex-cache/context/63cdb1aecb6460757eca78b5141d56c4/trees/f11a54178c00c3cdaccd8417314427ac.tma LuaTools | saving configuration in ///home/yulewang/tex/texmf-cache/luatex-cache/context/63cdb1aecb6460757eca78b5141d56c4/trees/f11a54178c00c3cdaccd8417314427ac.tma LuaTools | compiling configuration to ///home/yulewang/tex/texmf-cache/luatex-cache/context/63cdb1aecb6460757eca78b5141d56c4/trees/f11a54178c00c3cdaccd8417314427ac.tmc LuaTools | locating list of /home/yulewang/tex/texmf-local LuaTools | locating list of /home/yulewang/tex/texmf-linux LuaTools | locating list of /home/yulewang/tex/texmf-project LuaTools | locating list of /home/yulewang/tex/texmf-fonts LuaTools | locating list of /home/yulewang/tex/texmf-context LuaTools | locating list of /home/yulewang/tex/texmf-extra LuaTools | locating list of /home/yulewang/tex/texmf LuaTools | scanning path /home/yulewang/tex/texmf-linux LuaTools | 91 files found on 9 directories with 0 uppercase remappings LuaTools | scanning path /home/yulewang/tex/texmf-context LuaTools | 1310 files found on 125 directories with 0 uppercase remappings LuaTools | scanning path /home/yulewang/tex/texmf LuaTools | 2381 files found on 71 directories with 60 uppercase remappings LuaTools | preparing files in ///home/yulewang/tex/texmf-cache/luatex-cache/context/63cdb1aecb6460757eca78b5141d56c4/trees/5ff63bc52b0899f5d4695d75d1c8514d.tma LuaTools | saving files in ///home/yulewang/tex/texmf-cache/luatex-cache/context/63cdb1aecb6460757eca78b5141d56c4/trees/5ff63bc52b0899f5d4695d75d1c8514d.tma LuaTools | compiling files to ///home/yulewang/tex/texmf-cache/luatex-cache/context/63cdb1aecb6460757eca78b5141d56c4/trees/5ff63bc52b0899f5d4695d75d1c8514d.tmc LuaTools | preparing files in ///home/yulewang/tex/texmf-cache/luatex-cache/context/63cdb1aecb6460757eca78b5141d56c4/trees/6e2168099f58cbef07851e598e514561.tma LuaTools | saving files in ///home/yulewang/tex/texmf-cache/luatex-cache/context/63cdb1aecb6460757eca78b5141d56c4/trees/6e2168099f58cbef07851e598e514561.tma LuaTools | compiling files to ///home/yulewang/tex/texmf-cache/luatex-cache/context/63cdb1aecb6460757eca78b5141d56c4/trees/6e2168099f58cbef07851e598e514561.tmc LuaTools | preparing files in ///home/yulewang/tex/texmf-cache/luatex-cache/context/63cdb1aecb6460757eca78b5141d56c4/trees/23216e94fb804835110a994ec20c8ebd.tma LuaTools | saving files in ///home/yulewang/tex/texmf-cache/luatex-cache/context/63cdb1aecb6460757eca78b5141d56c4/trees/23216e94fb804835110a994ec20c8ebd.tma LuaTools | compiling files to ///home/yulewang/tex/texmf-cache/luatex-cache/context/63cdb1aecb6460757eca78b5141d56c4/trees/23216e94fb804835110a994ec20c8ebd.tmc LuaTools | LuaTools | runtime: 0.118 seconds yulewang@yulewang-laptop:~$ luatools --ini --compile --verbose cont-en LuaTools | version 1.1.1 -

mktexlsr in minimals
by Jean Magnan de Bornier 27 Jan '08

27 Jan '08

Hi all, Having installed the minimal distro from http://minimals.contextgarden.net/ on my linux box (in my home directory) I added some own modules in /home/jean/lua/context/tex/texmf-context/tex/context/extra an tried various texhash and mktexlsr: mktexlsr lua/context/tex/texmf-context/tex/context/ texhash lua/context/tex/texmf-context/tex/context/ But these are still not found and I had to specify the complete path of the modules! This seems specific to the minimals -- Jean

t-lilypond, placement of oversized lines.
by David Wooten 27 Jan '08

27 Jan '08

Greetings all, In tinkering around with the lilypond module, oversized lines of notation do not get adjusted into the left margin as this bit of code seems to be trying to achieve: ---> %D %D TODO: Get the relevant dimension directly from lilypond, %D to place the instrument name into the left margin for %D short snippets as well. %D If we are not in the middle of some text, we have to check %D whether lilypond created an image that is wider than requested: %D It places the instrument names in the left margin. %D \ifvmode \getfiguredimensions[\lily!filename.pdf]% \leavevmode% \newdimen\FigWidth \FigWidth=\figurewidth \ifdim\FigWidth>\localhsize \!!dimena=\localhsize \advance\!!dimena by-\FigWidth \noindent\hskip\!!dimena \fi \fi \externalfigure[\lily!img]% \egroup% }% <--- This includes lines which have an instrument name, as mentioned in the comments, and also includes piano notation, which has a special bracket on the left joining the two staffs. Can anyone help me out here? Best, David

Hi, in the garden I read that editsnc in 2003 was regarded the successor of pdfsync. Anybody has experience with one of them? Or the other way round: I am interested in pdf/source sync. Any recommendations? Thanks, Steffen

shading in metapost
by Thomas A. Schmitz 24 Jan '08

24 Jan '08

Hi all, I have a somewhat silly question about metapost/metafun. To emphasize parts of a picture, I place a bright red arrow or circle/ellipse on top of the picture. I would like to make this arrow more visible by putting a shade beneath it (I attach a jpg that will hopefully show the desired effect). Right now, I simply draw the arrow twice with a transparent black color, once with a smaller pencircle, so the effect is like a shadow that is darker in the center than at the edges. However, I think the effect would be more dramatic if I could have a transparent area with a smooth grading. Is this possible at all in metapost? filling a path with a transparent AND shaded color? All best Thomas
