Dear list, I'm using an updated Context minimals beta, and can't get autohang to work (in Mark IV). "autohang=yes" seems to be ignored.

invoices: make module or wikify
by Peter Münster 14 Jan '14

14 Jan '14

Hi, I'm writing my invoices like this: \environment e-invoice \beginInvoice \startInvItem[amount=123] bla bla 1 \stopInvItem \startInvItem[amount=456] bla bla 2 \stopInvItem \endInvoice If anybody is interested (e.g. for using it, making a module or wikifying), then I can send my files (no time to do it myself...) There are also calculations: \environment e-calculation \beginCalculation \startCalcItem[title=Title 1][hours=123] Do this and that, bla bla bla. \stopCalcItem \startCalcItem[title=Title 2][hours=456] Do something else, a lot of work. \stopCalcItem \endCalculation -- Peter

[***SPAM***] Invoice Example
by hwitloc＠gmail.com 14 Jan '14

14 Jan '14

I copied the three files required for the invoice example on the wiki garden. invoice.tex, invoicefunctions.tex, adn invoicesetup.tex $ context invoice.tex The above compiles without error, but the resulting pdf doesn't give me what I would expect. There is a " Regression in latest release of iT E X " In the main body of the document, which I don't think should be there. My setup: mtx-context | current version: 2013.09.03 16:23 Is the source out of date with the context version I am using or am I missing something? Thanks

\defineframedtext take precedence over \defineframed and add "extra padding"
by Elspeth McGullicuddy 13 Jan '14

13 Jan '14

In the following example \defineframedtext take precedence over \defineframed, and also I don't know how I can get rid of the "extra padding" (looks like a good \baselineskip before the text). (What I want is the first output, but with the readability of \startXY \stopXY) As for the "take precedence", I can change the name; But for the extra padding I don't know how to remove it. I could add a \vskip-\baselineskip at the beginning, but there is probably a better solution. (By the way, the construction \blueframed{\startformula hello\stopformula \input knuth} behave badly.) %%%%%%%%%%%%%%%%% \starttext \setupcolor[x11] \defineframed [blueframed] [width=local,frame=off,rulethickness=2mm,backgroundoffset=1mm,% align=yes,background=color,backgroundcolor=lightblue,% corner=round,radius=1.5mm] \blueframed{\input{knuth}} \defineframedtext [blueframed] [width=local,frame=on,%rulethickness=2mm,backgroundoffset=1mm,% margin=no, align=yes,background=color,backgroundcolor=lightblue,% corner=round,radius=1.5mm] \blueframed{\input{knuth}} \startblueframed \input{knuth} \stopblueframed \stoptext %%%%%%%%%%%%% Regards, Chris

Include PDF Fails

Hi, I am trying to include a single test page in my document. The following code fails to set the PDF as the background layer for the cover page.

Bug in \placefigure[right]?
by Mari Voipio 13 Jan '14

13 Jan '14

Hello! For a while I've been baffled by a weird bug where sometimes I get overset text when using \placefigure[right]. The problem appeared sometime this autumn in places where everything has worked before. This far I've (reluctantly) worked my way around the bug by using hard line breaks where needed, but the current project has so many of those spots that a more flexible solution would be nice. On the other hand, just because I have so many of them and some appeared today, I realized that the problem can be related to {\tfx } in the beginning of the line. Here's a minimal example: ============ \starttext \placefigure [right][cow] {A cow} {\externalfigure[cow]} {\tfx SET TIME/DATE} allows you to (re)set the instrument date and time. Time is set by inputting a certain amount of digits. Possible inputs are 4, 6, 8 and 12 digits. To set hours and minutes, input 4 digits. To set day of month and time input 6 digits. To set month, day and time input 8 digits. To set year, month, day and time input 12 digits. In all cases seconds can be set by separating them with a dot. The format can be seen below. \input tufte \stoptext =============== I know it is not beautiful, but I'm doing something very specific where this is needed. In a real pinch I can probably rewrite every problem sentence to put the \tfx in the middle instead of the beginning, but this still doesn't make the original problem go away. (Although I may be the only one bothered by it...) Mari PS. Hmm... Same thing if I use {\sc blabla} so while I reallly should switch to small caps, that is not the solution. PS2. I just tried with \placefigure[left] and I get overset text with it, too.

Re: [NTG-context] setuphead for in-paragraph head ?
by Jean-Guillaume 13 Jan '14

13 Jan '14

But this: \definehead [Exercise] [subsection] [after=] \starttext \startExercise [title=This is the exercise's title] The exercise's content. \stopExercise \stoptext results to: 1 This is the exercise's title The exercise's content. and I would like it to be: 1 This is the exercise's title The exercise's content. (When I can typeset that, I will see about formatting the number and so on.) I'm sorry it wasn't very clear. Now I understand that I misunderstood \startExercise{...} for \startExercise[title=...] and that's why I was confused about which newline I want to get rid of. Jean-Guillaume

kpfonts, math, type 1 font
by Elspeth McGullicuddy 11 Jan '14

11 Jan '14

Hi everybody, (best wishes for this new year by the way). There is this font: http://www.ctan.org/pkg/kpfonts Which is a postscript type 1 font, text and math. I've copied the files in the right places in the ${HOME}/texmf tree. And a call to: mtxrun --script fonts --list --all --pattern=*kp*, after a mtxrun --script fonts --reload seems to indicate that it is found by context all right. But now I haven't got the faintest idea on how to use it in a ConTEXt document -- text + math. My ConTEXt is beta not older than a fortnight. All examples I've found that could possibly apply were at least far too complicate for my understanding, also likely outdated. Regards, Chris

server downtime on Monday 2013-01-13

Hi, on Monday (13th January) afternoon (European time) there might be shorter black-outs on one of the contextgarden.net servers and the ctan.ijs.si mirror. In particular this could effect the "minimals" (the standalone ConTeXt distribution) which you can also find on the mirror rsync://metatex.org/minimals and other less critical sites (subversion - only used for developers, meeting pages, ConTeXt Group, ...). The wiki won't be affected. Mojca

Multipage xtables starts at the wrong page

Hello everyone, I'm using ConTeXt to write a technical manual and I'm facing with some strange behavior I don't know how to overcome. I need a multipage table and I'm using the xtables. This is a (stripped down) version of a part of my document: \mainlanguage [en] \setupxtable [externaldocs] [split=repeat, header=repeat, bodyfont=8pt, foregroundstyle=\ss, option=stretch, align=middle, frame=off, bottomframe=on, framecolor=elitalblue] \setupxtable [externaldocsheader] [background=color, backgroundcolor=black, foregroundcolor=white, foregroundstyle=\ss\bf] \starttext \chapter{Introduction} \startxtable [externaldocs] \startxtablehead \startxrow [externaldocsheader] \startxcell AD No. \stopxcell \startxcell Title \stopxcell \startxcell Doc No. \stopxcell \startxcell Issue \stopxcell \startxcell Date \stopxcell \startxcell Applicability \stopxcell \stopxrow \stopxtablehead \startxtablebody \dorecurse{60}{ \startxrow \startxcell AD No. \stopxcell \startxcell Title \stopxcell \startxcell Doc No. \stopxcell \startxcell Issue \stopxcell \startxcell Date \stopxcell \startxcell Applicability \stopxcell \stopxrow } \stopxtablebody \stopxtable \stoptext What I get, however, is a table that starts at page 2 and not just after the chapter head. If the number of rows is smaller and the table fit the first page, then it starts at the right place. What I'm doing wrong? Thank you very much, Marco

Mixing math and text font

Fallback for mathematical lowercase h and hyphen

Malayalam shaping with mkiv/LuaTeX
by Rajeesh K Nambiar 09 Jan '14

09 Jan '14

Hello, especially Hans and Kai, I have succeeded to an extent in adding Malayalam shaping to the existing Devanagari shaping. Being a complete novice in Lua and mkiv, I'm at a point where your expertise is needed to proceed further. Please find the attached patch, test case listed below and expected rendering for comparison. Additionally needed to support: 1. Decomposing 2 part Matras (dependent vowels) - 0D4A, 0D4B, 0D4C for Malayalam [Test cases 2 & 4]. This is needed (at least) for Tamil also. I guess it is as simple as replacing one code point with 2 others - example: replace 0D4A with 0D46, 0D3E. See page 3 of this Unicode standard: http://www.unicode.org/charts/PDF/U0D00.pdf 2. Handling "pref" opentype feature for v2 opentype spec (script tag "mlm2"). This is required for Malayalam Ra ligature, the glyph is formed correctly but it needs to be reordered as pre-base to the base syllable [Test case 1]. (Note that the old spec "mlym" handles "Ra form" as "pstf" and no reordering required). You can observe the difference in Test case 5 - Ra form should be attached to first consonant instead of second one ("mlm2" needs glyph formed by Virama+Ra to be reordered as pre-base to first consonant, while "mlym" doesn't need to). 3. Handling "pstf" opentype feature. It works mostly [Test case 8], except when a post-base Matra follows [Test case 9]. 4. Test cases 6 & 7 shows an example where glyph formation fails when a "pstf" Ya follows. This works correctly with some other conjuncts, though. 4. font-odv.lua hard coded Devanagari Virama (094D) and Ra (0930) in certain places, which needs to use table values to handle other scripts. 5. I had to change "methods.deva" to "methods.mlym" and "methods.dev2" to "methods.mlm2" to get this working, not sure how best to handle multiple scripts. 6. There are other cases like Dot-reph (0D4E) which uses GPOS table and requires reordering as post-base to the syllable follows it, but I haven't looked into them yet. i) The font used is Rachana, which supports both "mlm2" and "mlym" specs, can be downloaded from here: http://download.savannah.gnu.org/releases/smc/fonts/malayalam-fonts-6.0/Rac… You can switch to "mlm2" and "mlym" in test case. ii) Expected rendering of this test case: http://rajeeshknambiar.fedorapeople.org/ConTeXt/context-test.png iii) Test case: ----------- 8< --------- \usemodule[font-odv] \definefontfeature[malayalam][mode=node,language=dflt,script=mlm2,akhn=yes,blwf=yes,half=yes,pres=yes,blws=yes,psts=yes,haln=no] %\definefontfeature[malayalam][mode=node,language=dflt,script=mlym,akhn=yes,blwf=yes,half=yes,pres=yes,blws=yes,psts=yes,haln=no] \starttypescript [serif] [rachana] [name] \definefontsynonym[Serif] [file:rachana][features={malayalam}] \stoptypescript \starttypescript [rachana] \definetypeface[rachana][rm][serif][rachana][default] \definetypeface[rachana][mm][math] [modern][default] \stoptypescript \setupbodyfont[rachana] \starttext 1. \char"0D15 \char"0D4D \char"0D24 \char"0D4D \char"0D30 \\ % ക്ത്ര 2. \char"0D15 \char"0D4D \char"0D24 \char"0D4D \char"0D30 \char"0D4B \\ % ക്ത്രോ 3. \char"0D38 \char"0D4D \char"0D2A \char"0D4D \char"0D30 \\ % സ്പ്ര 4. \char"0D38 \char"0D4D \char"0D2A \char"0D4D \char"0D30 \char"0D4C \\ % സ്പ്രൌ 5. \char"0D24 \char"0D4D \char"0D30 \char"0D2A \\ % ത്രപ 6. \char"0D24 \char"0D4D \char"0D38 \\ % ത്സ 7. \char"0D24 \char"0D4D \char"0D38 \char"0D4D \char"0D2F \\ % ത്സ്യ 8. \char"0D15 \char"0D4D \char"0D2F \\ % ക്യ 9. \char"0D15 \char"0D4D \char"0D2F \char"0D42 \\ % ക്യൂ \stoptext ----------- >8 --------- Let me know if you need additional information or clarifications on test cases.

betas
by Hans Hagen 09 Jan '14

Hi, As some of you might have noticed, we're in transition to luatex 0.80 (currently 0.78.1). This binary is somewhat faster with respect to nodes without modification of Lua code, but it also provides an additional node field access mechanism. Luigi and I spent quite some time on getting that done and in the process some 70 context files were adapted (as we needed to test). However, it's likely that I have missed some needed changes. As both access mechanisms cannot be mixed, one has to be consistent in usage. Also, the somewhat faster (new) usage is more sensitive for errors so it has to be used with robust (proven) code (read: pluggable code can best use the traditional node field accessors which also have been sped up). And of course it only makes sense for very demanding cases (as stock luatex is already rather efficient now), think of devanagari (where we can get 50% faster) and complex arabic (some 25%). As ConTeXt spends > 50% of its time in Lua it might make a difference in other places too. Anyway, for instance the 175 fonts-mkiv manual processes 10% faster due to this and sometimes more can be achieved (it really depends on how much Lua enhanced mechanisms are used). Roughly I get on my win 8.1 64 bit laptop for the font manual: 10 sec luatex 0.77 with previous context code base 10.25 sec luatex 0.77 with current context code base 9.00 sec luatex 0.78 with current context code base 7.50 sec luajittex 0.78 with current context code base (This manual loads quite some fonts in the process.) In case you wonder why speed is an issue: it really matters when tex is used as a service, and I like fast edit-test cycles too. The target is to get 20 pps or more even for complex documents. It's not that hard to get 550 pps for simple 1000 page one-word-per page documents but when much more kicks in we quickly drop to 15-20 pps. Also, Luigi and I also want to reach reasonable speeds on android phones (triggered by Harald's experiments at the context meeting) but that's another topic.

\setcharactercasing misbehaviour
by Marco Patzer 09 Jan '14

09 Jan '14

Hi, \setcharactercasing requires a new paragraph to work. Seems like a bug to me. \starttext \setcharactercasing[Word]foo %% Uppercase \setcharactercasing[Word]bar %% lowercase \setcharactercasing[Word]bar %% Uppercase \stoptext Marco

Hi, the following example exceeds TeX's capacity: \mainlanguage [deo] \starttext \unit{10 square metre} \stoptext Marco
