How to make startalignment middle not change the linewidth
by Aditya Mahajan 16 Aug '06

16 Aug '06

Hi, It seems that startalignment[middle] does not like long lines. Consider the following example (not strictly minimal, but I can not get such a marginal case with default setup). \setuppapersize[letter][letter] \setuplayout[ width=middle, height=middle, location=middle, topspace=.75in, bottomspace=0.75in, backspace=0.75in, cutspace=0.75in, leftmargin=0in, rightmargin=0in, leftmargindistance=0in, rightmargindistance=0in, header=0in, footer=0in, headerdistace=0in, footerdistance=0in, ] \definetypeface[ieee] [rm] [serif] [times] [texansi] \definetypeface[ieee] [mm] [maths] [modern] [texansi] \setupbodyfont[ieee,10pt] \definefont[TitleFont] [Regular at 24pt] \setvariables[paper] [ title={Optimal Performance of Feedback Control Systems with Limited Communication over Noisy Channels}] \starttext {\TitleFont\setupinterlinespace \getvariable{paper}{title} \blank[1.0em]\endgraf} \startalignment[middle] {\TitleFont\setupinterlinespace \getvariable{paper}{title} \blank[1.0em]\endgraf} \stopalignment \stoptext How can I get the same linebreaking as the first case, but with each line middle aligned?

nonbreakablespace

Hi, Suddenly nonbreakablespace stopped working for me :-( It works in the garden so I guess that something is wrong in my setup. Can someone test whether this compiles fine at their end? \starttext A~B \stoptext For me, this makes context hang!! Aditya

Extra vertical space in intertext
by Aditya Mahajan 16 Aug '06

16 Aug '06

Hi, There is an extra vertical space in the first set of formulas, while the vertical spacing in the second set appears to be fine. I can not figure out why this should happen. Even if you comment the setupformulas line, the first set of formulas seem to allocate more space for the intertext. \setupformulas[align=right,spacebefore=none,spaceafter=none] % There appears to be extra space, even if I put % spacebefore=spaceafter=big % align = right is for visualization purpose only \starttext \startTEXpage \startformula \startalign \NC A \NC B \NR \intertext{test} \NC C \NC D \NR \stopalign \stopformula test outside formula \startformula \startalign \NC A \NC B \NR \intertext{test} \NC C \NC D \NR \stopalign \stopformula \blank[big] \startformula \startalign \NC \int_0^1 \NC B \NR \intertext{test} \NC \int_0^1 \NC D \NR \stopalign \stopformula test outside formula \startformula \startalign \NC \int_0^1 \NC B \NR \intertext{test} \NC \int_0^1 \NC D \NR \stopalign \stopformula \stopTEXpage \stoptext And what is happening with the start stop TEX page here. Why is the last line cut off! Thanks, Aditya

figure directory is sort of searched
by Sanjoy Mahajan 16 Aug '06

16 Aug '06

I still can't figure this problem one out, from a few months ago, and it happens with a recent ConTeXt (2006.08.08 21:51). The figure searching code gets confused if a file of the same basename (but in a different directory) has already been loaded. Here is a minimal min.tex to show what I mean: \starttext \setupexternalfigures[directory={1}] \placefigure[here][ch1fig]{should be 1/fig-1.pdf}{\externalfigure[fig-1.pdf]} \setupexternalfigures[directory={2}] \placefigure[here][ch2fig1]{should be 2/fig-1.pdf}{\externalfigure[fig-1.pdf]} \placefigure[here][ch2fig2]{should be 2/fig-2.pdf}{\externalfigure[fig-2.pdf]} \stoptext Probably it's a silly idea to use \setupexternalfigures within the body, but the same problem happens when using components (where each component's preamble has a similar line), where it makes more sense. Here is the directory structure, and all the files are attached as a small (15KB) .tgz: min.tex 1/fig-1.pdf 2/fig-1.pdf 2/fig-2.pdf The final (third) figure is correctly found as 2/fig-2.pdf. But the second figure is reused from 1/fig-1.pdf because another fig-1.pdf has already been found: as 1/fig-1.pdf. Here is the relevant bit from the texexec output: <./1/fig-1.pdf> figures : dimensions of 1/fig-1.pdf loaded from figurefile itself (./min.tuo) (/home/sanjoy/texmf/tex/context/base/pdfr-ec.tex) floatblocks : 1 placed figures : figureobject fig-1.pdf is reused floatblocks : 2 placed <./2/fig-2.pdf> figures : dimensions of 2/fig-2.pdf loaded from figurefile itself floatblocks : 3 placed One part of ConTeXt does know the right figure path. A \getfiguredimensions[fig-1.pdf] after the second \placefigure will trigger a kpathsea search for 2/fig-1.pdf, which it finds. But it still loads 1/fig-1.pdf, which is why I've said 'sort of searched' in the subject line. It seems that the decision about whether a figure is already loaded is made in core-fig.tex, in \def\calculateexternalfigure[#1][#2][#3][#4][#5][#6]% ... \ifcase\figurestatus \let\@@efframe\v!on \let\@@efobject\v!no \showmessage\m!figures1\@@effilename \or \showmessage\m!figures2\@@effullname \or \showmessage\m!figures3{\@@effullname,\@@eflenttype}% \or \showmessage\m!figures4\@@effullname \or \showmessage\m!figures5{\@@effullname,\@@efloadname}% \or % no message \doifnot\@@efsymbol\v!yes{\showmessage\m!figures8\@@effullname}% \fi ... The "no message" comment suggests that when \figurestatus isn't set, the message shown is figures8, which is 8: figureobject -- is reused But I couldn't figure out who sets \figurestatus and where the judgement of 'already loaded' is made. The comment at the beginning of the above \def ("this whole mess needs a clean up anyway") scared me off :-) -Sanjoy `A society of sheep must in time beget a government of wolves.' - Bertrand de Jouvenal

This was brought in the diskussion by mistake. In section 1.8 grid=line was introduced as a shortcut for grid={broad,high,depth}. But these two options are differing. Wolfgang

table questions
by wwl＠musensturm.de 15 Aug '06

15 Aug '06

Hallo! I have studied the table examples at contextgarden and have some questions. ---------------------- \|10 as a relacement for \VL gives me thicker vert. lines in that position only. How can I define a thicker vert. Line for the whole column? My attempts in \starttable[..\|10..] doesn't work. ---------------------- Why is there so little space between the two rows of the table below? \starttable[|l|p(.7\textwidth)|] \HL \NC bla1 \VL Eins \type{zwei} drei. Eins zwei drei. Eins zwei drei \type{vier} oder \type{sechs}l. Das ist der Leerraum zwischen den Spalten \type{n}. \FR \NC bla2 \VL Eins, zwei \type{drei} \LR \HL \stoptable ---------------------- The two tables in the example below are differing and show, that \SetTableToWidth{0pt} doesn't reset the situation. What is the defaultvalue/resetvalue for \SetTableToWidth{}? \starttable[|l|l|] \VL 11 \VL 12 \VL\FR \VL 21 \VL 22 \VL\LR \stoptable \SetTableToWidth{\textwidth} % some other table stuff \SetTableToWidth{0pt} \starttable[|l|l|] \VL 11 \VL 12 \VL\FR \VL 21 \VL 22 \VL\LR \stoptable ---------------------- Look at the example below: Without any \SetTableToWidth{} this table has neither hor. Lines nor green color. The gray is there. Why? Variant 1: This is an combination of two wiki-examples. The first column of the table is about \textwidth (a little bit smaller). Why? Between the gray and the second hor. Line there is a small white area. Same between green and fourth hor. Line. Hmm! Variant 2: Hor. Line and green area are .2\textwidth as expected. But gray area is about .6\textwidth and so is the column as a whole. Why that? Variant 3: All ok now. Even the spacing between coloured areas and lines is ok. \setupcolors[state=start] \starttext %\SetTableToWidth{.2\textwidth} % Variant 2 \SetTableToWidth{\textwidth} % Variant 1 \starttable[|lp(.45\textwidth)|lp(.45\textwidth)|] \HL \BL[1]\SR %\VL Command \VL Meaning \VL\SR % Variant 3 \NC Command \NC Meaning \SR \HL \NC \tex{NC} \NC next column \FR \NC \tex{NR} \NC next row \LR \HL \CL[green]\SR \NC \tex{AR} \NC automatic row \SR \HL \stoptable \stoptext ---------------------- Wolfgang

Apparently > the grid option for sectioning commands is handled differently. In my version of 'In the Details', dated 2002 chapter 1 deals with 'Snapping section heads' and section 1.8 is titled 'Snapping around (broad,high,depth).' Is there a newer variant of that manual?
