Lua & MP

Hello, is it possible that Lua gets value of a MetaPost variable? Let's have MetaPost code: z11=(0,0) z12=(1,1) z21=(0,1) z22=(1,0) aa[z11,z12]=bb[21,z22] So now aa = bb = 0.5. And I'd need to access MetaPost values 'aa' and 'bb' from Lua (e.g. in Lua: "local a = mpost.aa, b = mpost.bb"). Is it possible somehow? Regards, Lukas

composing characters in MKIV
by Mojca Miklavec 30 Sep '10

30 Sep '10

Dear Hans (or anyone else), There are some fonts (including Lucida) that don't have all the needed character. A font feature "compose=yes" has been added to MKIV, but that one doesn't work for Lucida or any other Type1 font. My current fallback is to use: % this doesn't help % \definefontfeature % [compose] % [liga=yes,kern=yes,tlig=yes,compose=yes] \beginNEWTEX \catcode`č=\active \catcode`Č=\active \defč{\buildtextaccent\textcaron c} \defČ{\buildtextaccent\textcaron C} \endNEWTEX But nevertheless a few questions: - Is there some "accessible" method to compose a few characters in the font (not too low-level) as opposed to using active characters? The code must be there already since this is supposed to work for OpenType fonts. - Is there any way to fix horizontal and vertical position of accents (on glyph-per-glyph basis; that one probably needs to be slightly more low-level; maybe using lfg files)? - Do lfg files work for non-opentype (Type1) fonts? Thanks a lot, Mojca

wrong sign or spacing in math/mkiv (at least in Lucida)
by Mojca Miklavec 30 Sep '10

Dear Hans, I'm not sure if the same problem would occur with other fonts as well (it is probably worth trying), but at least it happens with Lucida. Something is wrong with the spacing around the plus sign or maybe the wrong plus sign is taken (I suspect that). In MKII the formula is nicely aligned, while it looks ugly in MKIV. Here's the source: \beginOLDTEX \usetypescript[lucida][ec] \endOLDTEX \setupbodyfont[lucida] \starttext \startformula\startalign[align={left,left}] \NC m_{A_1'} \NC = (3+0+3+3+0+3) = 1 \NR \NC m_{A_2'} \NC = (3+0-3+3+0-3) = 0 \NR \NC m_{E'} \NC = (6+0+0+6+0+0) = 1 \NR \NC m_{A_1''} \NC = (3+0+3-3+0-3) = 0 \NR \NC m_{A_2''} \NC = (3+0-3-3+0+3) = 0 \NR \NC m_{E''} \NC = (6+0+0-6+0+0) = 0 \NR \stopalign\stopformula \stoptext Mojca

Problems with TABLE
by Patrick Gundlach 30 Sep '10

30 Sep '10

Hi, I still have some problems with TABLE: \bTABLE[frame=on] \bTR \bTD abc \eTD \bTD abc \eTD \bTD[frame=off,rightframe=on,rulethickness=1mm] abc \eTD \bTD abc \eTD \eTR \bTR \bTD[background=color, backgroundcolor=yellow] abc \eTD \bTD[nc=2,nr=2,background=color, backgroundcolor=yellow] \externalfigure[cow][width=.2\textwidth] \eTD \bTD abc \eTD \eTR \bTR \bTD abc \eTD \bTD abc \eTD \eTR \bTR \bTD abc \eTD \bTD abc \eTD \bTD abc \eTD \bTD abc \eTD \eTR \eTABLE 1) the cow sticks out of the cell. How can I pen the cow to the cell? 2) the third cell in the first row: when I turn on the right rule, the "abc" goes down. How can I have the abc on the baseline with the other ones in the first row _and_ have a right rule like that? Patrick

Still struggling with TABLE width
by Patrick Gundlach 30 Sep '10

30 Sep '10

Hi, as the subject says: I am still confused about widths of TABLE tables. \bTABLE % [option=stretch] \bTR \bTD A \eTD \bTD A \eTD \eTR \bTR \bTD[nc=2] %\hbox{A very very long text in one line, perhaps more} A very very long text in one line, perhaps more \eTD \eTR \eTABLE what I'd like to get is a table that is as wide as the text in the second row (A very very long text in one line, perhaps more) or at most the line width and the other two cells (the first line) stretched to mach that width (see image). I am pretty sure that this is possible, but how?!? Patrick

Hi List! I'm using TEI for a personal project, and I'd like to set it using ConTeXt. I'm having a bit of trouble getting started, and I was wondering if anyone has an environment file for TEI Lite that they'd like to share. It would be much appreciated! Thanks in advance, Mica

Hello, In Mk II, I need to place figures - with numbers and captions - but \placefigure is for floats and never places the figure [here]. Is there another way? Thanks, -- René Bastian www.pythoneon.org www.musiques-rb.org

poster in context
by Jan Pohanka 30 Sep '10

30 Sep '10

Hello, I wonder how to create a poster presentation using ConTeXt. It should have following layout. _____________________ | title, ... | _____________________ | | | | | text in 3 columns | | with titles etc. | | | _____________________ | acknowledgement | _____________________ Is there any way to fix the height of the depicted areas? Now I use columnset for the main text. Maybe layers can be useful? regards Jan -- Ing.

Problems with x-set-11.mkiv
by Cedric Mauclair 30 Sep '10

30 Sep '10

Hi, For some reason, line 248 of x-set-11.mkiv file (\blank[\v!line]) is not taken into account. As a result, when typesetting the setup-??.pdf files, the line of the first argument being described after a command is be too high and the word "optional" is mixed with it. When we change "\blank[\v!line]" with the low-level "\vskip\lineheight" it works as expected (or it seems). I understand this is not "beautiful", but it is a workaround for now. I am sure a fix will be available shortly. I noticed this when generating the seup file with the command (MkIV): "mtxrun --script context --run --interface=en --global --result=setup-en --purge x-set-12". There is no problem with the MkII equivalent (as it uses x-set-11.mkii instead): "texexec --int=en --pdf --global --result=setup-en --purge x-set-12". Regards. -- Cédric
