mkiv and MetaPost
by Otared Kavian 14 Jan '09

14 Jan '09

Hi all, I have a file which contains the lines below: I can typeset it and obtain a correct result with mkii, but not with mkiv (the second buffer named "axes-1" does not result in a MetaPost graphic when one says \processMPbuffer[axes-1]). The file and the resulting PDF can be found on http://www.kavian.fr/tex/bug-mkiv Thanks in advance for any help. Best regards: OK %%%%%% begin bug-metapost.tex \setupcolors[state=start] \starttext \startbuffer[axes-1] textextoffset := ExHeight ; numeric u ; u := .5cm ; vardef arrowheadonpath (expr p, s) = save autoarrows ; boolean autoarrows ; autoarrows := true ; set_ahlength(scaled ahfactor) ; % arrowhead p if s<1 : cutafter (point (s*arclength(p)+.5ahlength) on p) fi enddef ; path xox ; xox := (-u,0)--(8u,0) ; path yoy ; yoy := (0,-u)--(0,7u) ; draw xox withcolor blue ; draw yoy withcolor blue ; ahfactor := 4 ; % default is 2.5 fill arrowheadonpath(xox,1) withcolor .625blue ; % try .25 fill arrowheadonpath(yoy,1) withcolor .625blue ; % try .25 \stopbuffer \startbuffer[chemin-1] textextoffset := ExHeight ; numeric u ; u := .5cm ; z1 = (5u,0) ; z2 = z1 rotated 60 ; z11 = z1 rotated 15 ; z12 = z1 rotated 30 ; z13 = z1 rotated 45 ; z0 = (2u,0) rotated 30 ; path gamma ; gamma := (0,0)--(5u,0) ; draw gamma withpen pencircle scaled .4mm withcolor .625yellow ; path gammaR ; gammaR := z1..z11..z12..z13..z2 ; draw gammaR withpen pencircle scaled .4mm withcolor .625yellow ; dotlabel.bot (btex \switchtobodyfont[10pt] \strut $R$ etex, z1) ; path gammaRR ; gammaRR := z2--(0,0) ; draw gammaRR withpen pencircle scaled .4mm withcolor .625yellow ; dotlabel.top (btex \switchtobodyfont[10pt] \strut $R{\rm e}^{2{\rm i} \pi/n}$ etex , z2) ; dotlabel.rt (btex \switchtobodyfont[10pt] \strut ${\rm e}^{{\rm i}\pi/ n}$ etex , z0) ; label.rt (btex \switchtobodyfont[10pt] \strut $\Gamma_{R}$ etex , z11) ; fill arrowheadonpath(gamma,.4) withcolor .625yellow ; fill arrowheadonpath(gammaR,.4) withcolor .625yellow ; fill arrowheadonpath(gammaRR,.4) withcolor .625yellow ; \stopbuffer This file has been typeset on \currentdate{} at \currenttime, with \doifmodeelse{mkiv} {mkiv, LuaTeX revision \luatexrevision, (LuaTeX date stamp \luatexdatestamp)} {mkii, using the command: \type{texexec basic-test.tex}}, ConTeXt version \contextversion. % LuaTeX version \luatexversion, This MetaPost graphic is shown with mkiv: \placefigure[middle][-]{}{\processMPbuffer[chemin-1]} {} \blank but not this one \placefigure[middle][-]{}{\processMPbuffer[axes-1]} {} \blank nor this one \placefigure[middle][-]{}{\processMPbuffer[axes-1,chemin-1]} {} \stoptext

Fonts readily available in Context
by Curious 13 Jan '09

13 Jan '09

Hello All: There are quite a few fonts available in Latex with matching math fonts. The way a user like me who understands nothing about fonts can use them is to simply load a package. For example, for charter I can simply use the command \usepackage[charter]{mathdesign} Or, to use Palatino for text and some maching math fonts, I can use the command \usepackage{mathpazo} Are there fonts in Context with matching Math fonts other than Computer modern that can be used in an as simple manner,i.e., by just issuing few commands. If yes, can you please guide me to a resource which lists at least some of these fonts (again they should have matching math fonts) and the simple commands necessary to load them. I would find that really helpful Thanks very much.

Change the font to Charter
by Curious 13 Jan '09

13 Jan '09

Hello All, I have been using Latex for sometime and am thinking of switching to Context for at least some types of documents and hence have been trying it out. I love the charter font and tried to use the following commands to use the Charter font \definetypeface [charter] [rm] [serif] [charter] [default] [encoding=ec] \switchtotypeface [charter] [12pt,rm] However, when I compile the file with texexec I get the following warning: pdfTeX warning: pdftex (file ec-bitstrea-charter.map): cannot open font map file Can someone please help me fix this problem? I get the charter font output, however, the results are different from what I get with Latex. The letters seem more spread out and there seems to be more spacing between the words in the Context output. Could this be because of the above warning?

Catcode tables
by Wolfgang Schuster 13 Jan '09

13 Jan '09

Hi, can you fix the catcode related macros in syst-cat.mkiv, the macros did not work because a few macros are not define like \savecatcodetable and a few other are only defined in the MkII part like \catcodetable. Wolfgang

Undefined control sequence: \_

Hello, With the following test file, I get an "undefined control sequence" error: \starttext cc\_KNX \starttable[|c|] \NC cc\_KNX \NC\AR % here is the error \stoptable \stoptext But only with MKIV, no problem with MKII. Cheers, Peter -- http://pmrb.free.fr/contact/

beta
by Hans Hagen 13 Jan '09

13 Jan '09

Hi, Taco and I have decided to release a beta now. Officially there should have been a current end of december but there were too many things going on at the mkiv/luatex end to make that happen. Most changes concern mkiv anyway as we've kind of frozen mkii. Also, due to the number of changes in the lua code making a diff now would take too much time and not gain much. The next current will be in the second half of februari. Before that we will have a series of alphas that use the new structure related code. They're alpha because for a while there might be some compatibility issues (solving them depends in testers noticing them). This is also the first big deviation between mkii and mkiv, since it opens up the way to new functionality.

Check your posts

Hi all, Since yesterday evening localtime the ntg mail server switched to an external service for spam filtering. It is already clear that the mail server indeed handles much less spam now, so it looks like a great success. Still, it is a rigorous change, and for the new few days I want to ask everybody to keep an eye out for disappearing posts. This message is crossposted. If you want to reply, please do so to me personally, not to the lists. Best wishes, Taco

Hi, seems that color support is also broken in case of interaction. I get no red frame for the attached example.
