new beta
by Hans Hagen 11 Oct '19

11 Oct '19

Hi, I uploaded a new beta. Some might have noticed that stepwise some font support has been redone. We're talking of lmtx only here. For instance low level handling of color fonts as used for emoji but there are also other (often incomplete) fonts out there (overlay, png, svg) has become (on the average) a bit more efficient. It's somewhat tricky to satisfy viewers but at my end things work ok. It should also work in a cmyk only mode. As usual it's work in progress (and in this case very likely lmtx only). Also some first (runtime) metafun (2) font creation support has been added (was always possible but it's a bit more convenient now). An example can be found in: meta-imp-gamesymbols.mkxl (the file can be processed with the 'context' command and will produce an example). As usual imagination determines the limits of what context provides, so feel free to suggest more (examples). Again this is lmtx specific.

Documentation of change / Evolving documents
by Axel Kielhorn 11 Oct '19

11 Oct '19

Hi, I often have documents that are not finished but need to change over time. A client changes their mind, laws are changed, … While working with the document, I want to see the changes. When the document is finally finished, I only want to see the change history. I came up with the following. When the mode is „change“ the date (or version) is shown in the margin and the change is printed in red. Without mode „change“ only the change history is printed. What I want now is to change the layout of the register. Adding some vspace around the date and printing the date in bold. Is there a way to achieve this or am I on the wrong way? (Should the date be the indicator, thus giving me the layout I want?) \enablemode[change] \setuppapersize [A4][A4] \setuplayout [width=middle, backspace=1.5in, cutspace=1.5in, height=middle, topspace=0.75in, bottomspace=0.75in] \setupbodyfont[11pt] \defineregister [change] \setupregister [change] [ indicator=no %% no letter style=sansbold, %% headings textstyle=slanted, %% entries pagestyle=bolditalic, %% page refs n=1, %% columns ] \def\ChangeV#1#2{\change{#1+#2}\doifmode{change}{\inmargin{\tx #1}{\red #2\par}}} \def\ChangeD#1#2{\change{#1+#2}\doifmode{change}{\inmargin{\tx #1}{\red #2\par}}} \starttext \ChangeV{V. 1.0}{Fertig!} \input knuth \ChangeD{2018-12-22}{Fertig!} \ChangeD{2018-12-23}{Letzter Fehler beseitigt.} \input knuth \ChangeD{2018-12-23}{Allerletzter Fehler beseitigt.} Ende \startsection[title={History}] \placechange \stopsection \stoptext

\startitemize + "joinedup" ("nowhite") not working in footnotes?
by context＠vivaldi.net 10 Oct '19

10 Oct '19

Hello, in the following sample there is unwanted vertical gap between text "Foo" and the first item "- bar" in the footnote 1 (and also between "Bar" and "- bar") - see red arrows. The same code used outside the footnote behaves as expected - there is no vertical space. Is there anything special about handling itemization inside footnotes? My code: ---- \def\T{% \startitemize[joinedup,nowhite] \item bar \item baz \stopitemize } \def\U{% Foo \T Bar \T } \starttext \U \startitemize \item Item\footnote{\U} \stopitemize \stoptext ---- Best regards, Lukas

Problem inserting image within MP
by context＠vivaldi.net 10 Oct '19

10 Oct '19

Hello, this is a probably basic question, but the following code doesn't compile: ---- \setupbackgrounds[page][background={Bkg}] \defineoverlay[Bkg][\useMPgraphic{Bkg}] \startuseMPgraphic{Bkg} externalfigure "hacker.png"; \stopuseMPgraphic \starttext Ahoj \stoptext ---- with: " >> picture ! Isolated expression. <to be read again> ; <*> externalfigure "hacker.png"; ; I couldn't find an `=' or `:=' after the expression that is shown above this error message, so I guess I'll just ignore it and carry on. " I just want to insert a picture from within MP code. What am I doing wrong? Best regards, Lukas

Re: [NTG-context] OpenBSD install broken
by Damien Thiriet 08 Oct '19

08 Oct '19

Hi Mojca, Hi Robert I tried to install standalone according to your instructions, but I failed one more time. I did the following steps: mkdir context && cd context rsync -ptv rsync://contextgarden.net/standalone/setup/first-setup.sh . ./first-setup.sh Then I changed the line 4049 of bin/mtxrun to local platform="openbsd6.5-amd64" but I obviously did not understand what to do next: calling env PATH="$PWD/bin:$CONTEXTROOT/texmf-$platform/bin:$PATH" MTX_PLATFORM="$platform" \ ./bin/mtxrun --script ./bin/mtx-update.lua --force --update --make --engine=luatex --platform="$platform" --texroot="$CONTEXTROOT" $@ ends quite quickly, with this output mtx-update | available platforms: freebsd freebsd-amd64 linux linux-64 linux-armhf linuxmusl-64 mswin openbsd6.5 openbsd6.5-amd64 osx-64 solaris-intel solaris-sparc win64 resolvers | tds | no 'texmf-openbsd6.5-6.4' under tree '/home/<name>/context/' which is the same output as ./first-setup.sh before the change. (changed my home name to <name>) What did I do wrong? Greetings, Damien Thiriet

Dear list, I have the following sample: \setupinteraction[state=start, focus=standard] \starttext a\footnote{b} \stoptext Using latest beta from MkXL (2019.10.05 14:56), link form footnote to main text body doesn’t work. Latest beta from MkIV (2019.10.05 14:45) has no issue and the footnote link works perfectly fine. Could anyone confirm this issue with links in footnotes for LMTX? Many thanks for your help, Pablo -- http://www.ousia.tk

passing variables/data between context and lua
by Martin Althoff 08 Oct '19

08 Oct '19

Hi, I am trying to pass variables/data between context and lua. Lua would be used for calculations on data coming from context. Unfortunately I can't figure out what to do. The code below doesn't work, but is there to illustrate my idea. Any help would be much appreciated. Thanks, Martin \define\question{44} \starttext \startluacode local points = \question * 92 -- do some calculations with points and return to to context answer=42 \stopluacode % lots of Text in between The answer is \answer \stoptext

issue with JavaScript in Acrobat
by Pablo Rodriguez 08 Oct '19

08 Oct '19

Dear list, I have this minimal sample: \setupinteraction[state=start] \setupinteractionscreen[option=max] \startJSpreamble {varia} used now var transitions = [1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000]; var msecs = 0; function step_clock() { try { ++msecs ; if ((msecs >= (transitions[this.pageNum]/10)) && ( this.pageNum < this.numPages )) { ++this.pageNum; }; } catch (e) {} } advance = app.setInterval ("step_clock()", 1); advance.count = 0; \stopJSpreamble \starttext \dorecurse{10}{\startTEXpage[pagestate=start, offset=1em] \pagenumber \stopTEXpage} \stoptext Acrobat is required. And I have an issue with it Each slide takes a full second (1000 milliseconds). But the conditional in step_clock() needs to divide the elements from transitions array by ten. Otherwise it is ten times slower. Am I missing something here? Or why is "step_clock()" ten times slower than it should be? Many thanks for your help, Pablo -- http://www.ousia.tk

Printing catchword or kustode
by Jan Ulrich Hasecke 08 Oct '19

08 Oct '19

Hi all, Visiting a museum in Straßburg I saw an old book from Gutenbergs times where the first word of the next page was printed below the last line of the current page. The word, sometimes only a syllable of the first word from the next page, is called catchword or Kustode. They used it to ensure that they bind the pages in the right order. I think that it can also be of help if you read a book. Is this possible with ConTeXt? I could not find the word catchword, reclamans or kustode on the wiki.
