GSUB LookupType 6 in fea file not working
by Paolo Brasolin 10 Jan '16

10 Jan '16

Hello. I am trying to add some custom ligatures to a font using a feature file. Everything works just fine, until I try what is called a chained contextual substitution, i.e. a GSUB lookup of type 6. I am studying the specs from http://www.adobe.com/devnet/opentype/afdko/topic_feature_file_syntax.html#5… A simple example.fea that does not work for me is: languagesystem dflt dflt; lookup FOOBAR { sub B by Q ; } FOOBAR; feature foba { sub [A] B' lookup FOOBAR; } foba ; I'd expect it to replace B with Q only when preceeded by A. The same rule expressed with a lookup of type 8 works just fine: languagesystem dflt dflt; feature foba { sub [A] B' by Q; } foba ; Ultimately I would need to use multiple inline lookups, something like sub [A]' B' lookup FOO C' lookup BAR; Are inline lookups unsupported by the engine? That would seem strange to me. I'm probably missing some point, but I'm unable to find more documentation. Am I using the wrong syntax? Thanks to anyone who can shed some light.

Footnote rules for bidi document
by Mohammad Hossein Bateni 09 Jan '16

09 Jan '16

Hi, This has been previously discussed on the list but I didn't find a resolution to the issue. It might as well be my fault since I didn't go through the entire archive and I am needless to say new to CONTEXT. In a bidi text (Persian/English in my case), I would like the footnote rule to be placed on the right-hand side if and only if the first line of the footnote text is RTL. Is there a way this information can be obtained within a user-defined rulecommand. Ideally I'd like a rule=autodir attribute for notes in addition to the current left & right. Speaking of which, the left & right rules do not seem to work, or I misunderstand their point. When used (either left or right), the footnote rule disappears. \starttext \definenote[afootnote][paragraph=no,rule=right] \startalignment[r2l] righttoleft text\afootnote{\input ward } \input tufte \stopalignment \startalignment[l2r] lefttoright text\afootnote{\input ward} \input tufte \stopalignment \stoptext I see these defined in strc-not.mkvi <http://repo.or.cz/w/context.git/blob/HEAD:/tex/context/base/strc-not.mkvi> and still don't work with "% macros=mkvi" in the first line of the input file and when the file has extension mkvi. Is this some issue of mkiv vs mkvi? For what it's worth, I don't notice a reference to MKVI in the compilation output. Back to the main question, I can define my own rule as follows: \unprotect \def\myfootrule{% \ifvmode \dontleavehmode \hskip.8\hsize\blackrule [\c!color=\noteparameter\c!rulecolor, \c!width=.2\hsize, \c!height=\noteparameter\c!rulethickness, \c!depth=\zeropoint]% \endgraf \kern\strutdepth \fi} \protect Then I can use \definenote[afootnote][paragraph=no,rule=command,rulecommand=\myfootrule] to get a footnote rule on the right-hand side. If I can figure out whether the first line of the footnote text is RTL or LTR, an if-statement can do the trick I want. Somewhat related to this, I was wondering whether it's possible to define two note commands, say \footnote and \afootnote, that use the same counter but are otherwise completely different. I use TeXLive 2015 on Mac OS X, CONTEXT 2015.05.18 12:26, and LuaTeX, Version beta-0.80.0 (TeX Live 2015) (rev 5238). Thanks a lot! —MHB

error in latest beta
by Thomas A. Schmitz 08 Jan '16

08 Jan '16

Hi Hans, with yesterday's beta, I get an error when calling a module: tex error > tex error on line 65 in file /home/tas/texmf/tex/context/third/simpleslides/t-simpleslides.mkiv: ! Undefined control sequence <argument> \syst_modules_setup \syst_helpers_double_empty_one_spaced #1#2->#1 [{#2}][] <to be read again> \par l.65 55 \startmodule[simpleslides] 56 57 \unprotect 58 59 \setupmodule 60 [style=, 61 font=LatinModernSans, 62 size=17pt, 63 color=blue, 64 alternative=square] 65 >> 66 \usemodule 67 [simpleslides-fontsdefault] 68 Our module is trying to load submodules, in this case the file s-simpleslides-fontsdefault.mkiv. We had something similar a while ago, ConTeXt became more strict in the names it expected for modules, but that was resolved. An older beta (2015.11.19 19:13) works; I may have betas between these two on the computer in my office and can test those, if that helps. The definition of \syst_helpers_double_empty_one_spaced hasn't changed, AFAICS, and I couldn't see what caused the error in the changes of file-mod.mkvi. All best Thomas

ConTeXt update issue
by klerer＠sxmail.de 07 Jan '16

07 Jan '16

Dear list,I have experienced a problem updating the ConTeXt version I use on a current Linux operating system flavour beginning ca. two months ago.By that time, as was successfully applied several times before within the past year of me using ConTeXt, I initiated the update process on the bash console via one command recommended on the corresponding ConTeXt page: "sh ./first-setup.sh --context=current".Then, and on two other ocassions very recently, ConTeXt got stuck (after data had indeed been received and some actions concerning the usual update had been executed, too) giving back the following lines in the bash console that puzzled me a lot:"...This is LuaTeX, Version beta-0.87.0 (TeX Live 2016/dev) (INITEX) system commands enabled.(/home/ichhalt/context/tex/texmf-context/tex/context/base/cont-nl.mkiv (/home/ichhalt/context/tex/texmf-context/tex/context/base/context.mkiv (/home/ichhalt/context/tex/texmf-context/tex/context/base/syst-ini.mkiv! Undefined control sequence.l.1020 pdfoutput zerocount" I admit that this code example is quite short, but it is definitely the last that the whole ConTeXt update process returns-otherwise it stood still.What-except for uninstalling and re-installing ConTeXt-could help now? If ever possible, a conservation of my current ConTeXt installation appeared preferable to me.Thank you in advance.Best regards,Markus Hofstetter

Hello Hans, and so on! When there are different headers and footers in a chapter: 1. header: this is me. I write this in left and right pages. Then comes a subsection in this chapter 1.1 header: left side: this is my first chapter, right side : this is the second chapter. What have I to do then Uschi

Problems with TikZ and absolute positioning
by Michał Goliński 05 Jan '16

05 Jan '16

The following code: \usemodule[tikz] \starttext \starttikzpicture[remember picture,overlay] \node [xshift=1cm,yshift=1cm] at (current page.south west) [text width=7cm,fill=red!20,rounded corners,above right] { This is an absolutely positioned text in the lower left corner. No shipout-hackery is used. }; \stoptikzpicture \stoptext gives a blank page with a red box in the lower left corner. At least this is how it works in current TeXLive. When compiling, a temporary .pgf file is created with the following contents: \pgfsyspdfmark {pgfid1}{4661756}{46204089} When compiling with the current beta this doesn't work. If the .pgf file is already present, one gets: tex error > tex error on line 1 in file mwe.pgf: ! Undefined control sequence l.1 \pgfsyspdfmark {pgfid1}{4661756}{46204089} 1 >> \pgfsyspdfmark {pgfid1}{4661756}{46204089} When one removes the .pgf file, the compilation succeeds (with empty .pgf file), but in the PDF there is no red box, and the text is not in the lower left corner (although text is wrapped as if it were in a box). When compiling one gets the warning: Package pgf: Warning! Your graphic driver pgfsys-dvips.def does not support marking the current position. This warning is given only once. Non-PDF special ignored! Non-PDF special ignored! ... Is this a bug or maybe absolute positioning is done differently? Best regards Michal Golinski

When I click the play or forward button, there is no action at all. Is there something more I have to do? Thank you. Best regards, Dalyoung * Here is the version of ConTeXt in my Macbook.

[Bug report] TikZ + makeup + grid = blank page
by Paolo Brasolin 04 Jan '16

04 Jan '16

Hello. Consider the following MWE: \usemodule[tikz] \setuplayout[grid=yes] \starttext \startstandardmakeup Not nothing. \stopstandardmakeup \stoptext The output consists of two pages, the first being an unexpected and undesired blank. Removal of either tikz, grid or makeup is sufficient to make the blank disappear. I am failing to see how these three interact. My versions: This is LuaTeX, Version beta-0.80.0 (TeX Live 2015) (rev 5238) ConTeXt ver: 2015.05.18 12:26 MKIV current fmt: 2015.10.28 int: english/english The bug is reproduced also at live.contextgarden.net too Here is the related SE question: http://tex.stackexchange.com/questions/284972/tikz-causes-blank-page-in-fro… Can anyone explain the interaction or provide a workaround? Thanks. -Paolo
