columnset - float vertical spacing
by Jan Pohanka 30 Sep '10

30 Sep '10

Hello, I need to reduce vertical spacing around floats in columnset. I have tried \setupfloats command as in example below, but without succes. And what about columns balancing? I have read the columns.pdf manual, but I don't understand it clearly. [balance=yes] does not balance the columns even without the figures. regards Jan \definepapersize[poster][width=73cm,height=73cm] \setuppapersize[poster][oversized] \setuplayout[ header=0cm,footer=0cm, backspace=2.54cm,topspace=1.5cm, width=middle,height=middle, location=middle,marking=on] \setuppagenumbering[location=] \mainlanguage[en] \enableregime[utf8] \usetypescript[helvetica][ec] \setupbodyfont[helvetica,25pt] \setupindenting[always,small] \definecolumnset[cols][n=3,distance=1em,balance=yes] \setupfloats[frame=on,spacebefore=none,spaceafter=none,before=,after=] \starttext \showframe \startcolumnset[cols] \input knuth \input tufte \placefigure[][fig:stereoblock] {AAxxxm} {\externalfigure[xxx][width=0.8\textwidth]} \input knuth \input tufte \input knuth \input tufte \placefigure[][fig:stereoblock] {Axxxm} {\externalfigure[xxx][width=0.8\textwidth]} \input knuth \input tufte \stopcolumnset \stoptext -- Ing.

Lua programming conventions..
by Jaroslav Hajtmar 30 Sep '10

30 Sep '10

Hello, all.. Where can I read something about Lua programming conventions? I mean programming conventions labeling local and global variables, table fields, Lua variables in modules, variables in namespaces etc. etc... When names are written in capital letters, sign reserved for system variables, etc.? Thanx Jarda

Formatting in TOC
by Tomas Bures 29 Sep '10

29 Sep '10

Dear all, I would like to generate a table of contents, where each item should have a number, title and date. I use the user variables this way: \define[1]\ChapterListTextCommand{% #1\hskip 1.5em \hbox{ \doiftextelse{\structurelistuservariable{date}{(\structurelistuservariable{datum})}{} } } But actually I would like to align the date to some fixed horizontal position. Something like this: 1. Title of chapter 1 (9.2.2010) .... 5 2. Title of another chapter (10.3.2010) .. 10 3. A very long title of a chapter (10.5.2010) .. 34 4. Title of fourth chap. (8.4.2010) ... 25 Another complication is that I would like the line to snap to a grid. I tried it with framed, but I'm not good enough in ConTeXt. Please, any idea? Thank you, best regards, Tomas

metapost: unable to make mpx file error
by Alan BRASLAU 29 Sep '10

\startOT Wow! "experimental metapost version two" (does this mean that we get to play with precision?) \stopOT \startQUESTION The following minimal example yields an error: \starttext \startMPcode input circle ; \stopMPcode \stoptext where circle.mp contains a btex...etex sequence: draw fullcircle scaled 1cm ; label (btex 1 cm etex , (0,0)) ; The "input circle ;" will work if I comment-out or remove label ; The minimal example will work, of course, if the mp code is in my tex file. The error message is: mplib : loading 'metafun.mp' (experimental metapost version two) ! mp terminal: (circle.mp >> circle.mp >> circle.mpx !

While looking at Cambria, is there any typescript (or something similar) that defines for example Corbel or Candara as a companion to Cambria? Patrick

Calling Lua function from an external package
by Procházka Lukáš 29 Sep '10

29 Sep '10

Hello, I have the following problem. Let's have T~.lua file which defines a function: --- function F2() context("draw (0,0)--(5cm,0)") end print("T~OK!") --- Let's have MP-02.ctx ConTeXt source file: --- \starttext AAA \startluacode function F() context("draw (0,0)--(2cm,0)") end require("T~") context.startMPcode() F() -- F2() context.stopMPcode() \stopluacode \stoptext --- Such code works OK - produces .pdf with a text "AAA" and a horizontal line. You can find the text "T~OK!" in the compilation log - that means T~.lua was successfully loaded. When I remove comment marks in front of F2() (which is defined in T~.lua), so I get: --- \starttext AAA \startluacode function F() context("draw (0,0)--(2cm,0)") end require("T~") context.startMPcode() F() F2() context.stopMPcode() \stopluacode \stoptext --- the compilation to .pdf fails with the following error message: --- MTXrun | run 1: luatex --fmt="c:/ConTeXt/tex/texmf-cache/luatex-cache/context/f53042fa2e1c106bc7e3383ec8c3a00c/formats/cont-en" --lua="c:/ConTeXt/tex/texmf-cache/luatex-cache/context/f53042fa2e1c106bc7e3383ec8c3a00c/formats/cont-en.lui" --backend=pdf "./MP -02.ctx"This is LuaTeX, Version beta-0.63.0-2010090921 (rev 3873) \write18 enabled.
