expand date from CSV file
by Pablo Rodriguez 20 Dec '14

20 Dec '14

Dear list, I have the following sample: \usemodule[scancsv] \unexpanded\def\lineaction{ \Name\ arrived on \Date\\ } \setheader \setsep{;} \setfiletoscan{mail.csv} \starttext \filelineaction \stoptext that reads data from mail.csv: Name;Date ME;11/10/14 You;05/02/14 He;15/02/2014 She;03/03/12 It;03/03/14 My question is simple (and not related to CSV data import): how can I define a command (ConTeXt or Lua) that changes date format from DD/MM/YY to DD/MM/YYYY when required? Many thanks for your help, Pablo -- http://www.ousia.tk

Hi Luigi, > The example works if one copies colo-rgb.mkii as colo-rgb.tex in the same > folder of the example ... It is OK by changing line 46 in m-pstricks.mkii: \loadpstrickscolors{colo-rgb}} to \loadpstrickscolors{colo-rgb.mkii}} as Herbert said. In the recent beta's, the change was already done. Best, Akira

\startitem [reference=xxx]
by Alan BRASLAU 17 Dec '14

17 Dec '14

Hello, An item in an itemized list can have a reference: \startitemize [n] \item[first] This is a first item; \item[second] This is a second item. \stopitemize \in{item}[first] appears before \in{item}[second]. How does this work with \startitem\stopitem? I tried, of course: \startitem[reference=first] This is a first item. \stopitem Thanks. Alan

problem with \processaction
by Pablo Rodriguez 17 Dec '14

17 Dec '14

Dear list, I have the following sample: \def\SystemUser{whoami} \def\CheckUser{\processaction[\SystemUser][whoami=>whm]} \starttext \doifelse{\CheckUser}{whm}{This is the right user.} {This is the wrong user.} \doifelse{\SystemUser}{whoami}{This is the right user.} {This is the wrong user.} \SystemUser\ is \CheckUser \stoptext Why doesn’t the first \doifelse work? What am I missing there? Many thanks for your help, Pablo -- http://www.ousia.tk

command to get the text value?
by Pablo Rodriguez 16 Dec '14

16 Dec '14

Dear list, sorry for writing again on the same topic. The issue is important and I don’t know how to solve it. I have a different sample: \def\firstcommand{AAA} \def\secondcommand{aaa} \starttext \doifelse{\word{\firstcommand}} {\secondcommand}{Equal}{Not equal}. \stoptext I understand that A and a are different characters. Is there no command to get the pure text from another command? Or how could I get equal values in the sample above? Many thanks for your help, Pablo -- http://www.ousia.tk

[fontloader] positioning of diacritics
by Philipp Gesang 15 Dec '14

15 Dec '14

Good morning! This report by Github user SverreStausland has been lingering on the Luaotfload tracker for a while: There appears to be a difference between how certain faces of the Libertine family handle the placement of diacritics. With Version 5.1.2 of the family [0], the "RZI" version (fullname: “Linux Libertine O Semibold Italic”) shows a different behavior than its “RZ” companion (“Linux Libertine O Semibold”). Short demonstration in Context: \definefontfeature [ourfeats] [default] [mode=node] \starttext \start \definedfont [file:LinLibertine_RI.otf*ourfeats] V\char"0306 \stop \start \definedfont [file:LinLibertine_RZI.otf*ourfeats] V\char"0306 \stop \stoptext Note the misaligned combining breve above the latter. An equivalent test for Plain [1] shows that the correct position information is there somewhere in the font, since the Xetex engine typesets it correctly. Best regards, Philipp [0] MD5 hashes of the files: 4bfd3481c1486f5d1ea13304981df7a6 LinLibertine_RZI.otf 153765bd2b29d6026fb2fa0b198a4995 LinLibertine_RZ.otf [1] https://bitbucket.org/phg/lua-la-tex-tests/src/tip/pln-diacritics-1.tex

[fontloader] node injector / december 3 sync
by Philipp Gesang 15 Dec '14

15 Dec '14

Hi Hans, from the huge changeset two weeks ago: +texio.write_nl("The font code has been brought in sync with the context version of 2014.12.01 so") +texio.write_nl("if things don't work out as expected the interfacing needs to be checked. When") -- Message received ;) First off, thanks for bringing the fontloader into sync again. So far I haven’t noticed any obviously broken features. However, something is off with the node injector. We have a bug reported by Hironori Kitagawa that occurs with the ``palt`` feature in node mode: http://tug.org/pipermail/luatex/2014-November/004976.html Importing the shiny new font injector into the merged fontloader fixes the issue. FWIW here are test files https://bitbucket.org/phg/lua-la-tex-tests/src/tip/cnt-features-12-palt.tex https://bitbucket.org/phg/lua-la-tex-tests/src/tip/pln-features-12-palt.tex The Context version runs fine whereas the plain one does so only after my “fix”. The same is true for Context itself: replace font-inj.lua with node-inj.lua in the format to reproduce the issue. Is there a fix to the fontloader, perhaps only temporarily until the revised injector becomes ready? Best, Philipp

xtables in setups
by Andreas Schneider 15 Dec '14

15 Dec '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, I'm currently setting up a xml -> pdf template for some technical documentation and wanted to use xtables. However they don't seem to work when within a setup/xmlsetup. Small example (without XML, for the sake of simplicity): ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ \starttext \startsetups test \startxtable \startxrow \startxcell Foo \stopxcell \startxcell Bar \stopxcell \stopxrow \stopxtable \stopsetups \setups[test] \stoptext ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Causes: * tex error > error on line 0 in file : ! Emergency stop Is there anything I'm doing wrong here or did I stumble upon a bug? (If there is no easy fix here, I'm probably going to use LUA to parse the XML and write the TeX part from there which means I could circumvent the need for setups.) Best regards, Andreas -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iF4EAREIAAYFAlSPKQwACgkQIxziJkiYZxFTYAEAxsgkiYolYatIyoCPQNDlmp0f pmSdU5HtzfCw2V2ZKs4BAK5E6Qu/ZrE5mIRD2qupwAffokpkIefMlLhzLPYuCTx7 =QetB -----END PGP SIGNATURE-----

PSTricks in Context

> Anyway, the version in TeX Live now runs, but creates wrong results > (it prints out "(0,0)(3,3)" instead of drawing the line for example). In the case of mtx-context | current version: 2014.12.11 12:02 The following is OK. % % context test.tex % \usemodule[pstricks] \starttext \startmidaligned \startPSTRICKS \pspicture(0mm,0mm)(30mm,30mm) \psline(0,0)(3,3) \endpspicture \stopPSTRICKS \stopmidaligned \stoptext Of course there are examples that don't match ConTeXt. Best, Akira

help with command definition
by Pablo Rodriguez 14 Dec '14

14 Dec '14

Dear list, I have the following sample: \setuppapersize[A7,landscape] \def\slide#1{\startstandardmakeup#1\stopstandardmakeup} \def\codeslide#1{\startstandardmakeup \starttyping#1\stoptyping\stopstandardmakeup} \starttext \startstandardmakeup \ConTeXt \stopstandardmakeup \slide{\ConTeXt} \slide{\starttyping\ConTeXt\stoptyping} \codeslide{\ConTeXt} \startstandardmakeup \starttyping \ConTeXt \stoptyping \stopstandardmakeup \stoptext And two questions: Why the third makeup gives such verbose output? Why does \codeslide not work? I guess this may be related to expansion, but I must confess that I don’t know what expansion really is. Many thanks for your help, Pablo -- http://www.ousia.tk
