Firstly: that is the way it works in mkii. Why does mkiv do it differently? Secondly: You use -in my opinion- next, because the first paragraph is clear that it is a new paragraph. After a bank (or a flowchart) it is clear that there starts a new paragraph.

但有些动物比其他动物更平等。所有动物都生而平等，但有些动物比其他动物更平等。
\stopbuffer
\getbuffer[test-footnote]
\blank
测试\footnote{\getbuffer[test-footnote]}
\stoptext
Just I added \setupfootnotes[style={\setscript[hanzi]}], the line
break can work.
The problem is still in the beta 2011.04.13.

It has to be fixed by Hans. ConTeXt looks only for the label of the current

sectionblock (e.g. “chapter” for the bodypart and “appendix” for the
appendices).

LuaTeX has total unicode representation in terms of content (are unicode characters possible for macro declarations? this is unclear at this point but clearly useful..)

with the current context versions which works fine. However, if I insert the

figure out what causes the problem.
The error comes from the \floatcaptionattribute and \destinationattribute
commands. \destinationattribute expects a number as argument (which is stored
in the \currentfloatattribute macro) but with a split float it gets a empty
argument.
A split float sets \usesamefloatnumber to true and there \currentfloatattribute
is \empty.
\long\def\docompletefloat#1#2#3#4#5% #1:floatclass #2:reference #3:optionlist

Yes but they need catcode 11.

[NTG-context] Displaying text on a page in several steps
I want to have several points on a page, but have them displayed one after the other. For example, the complete page is: MY POINTS 1. The first point 2. The second point 3. The third point 4. The fourth point Initially you see: MY POINTS 1. The first point After giving space you see: MY POINTS 1. The first point 2. The second point When giving again space, you see: MY POINTS 1.

[NTG-context] OT: drawing graphs: Asymptote, Gnuplot, MetaFun, …
Dear ConTeXt folks, I need to plot some random walks similar to [1], but for example I need to emphasize certain sections of the plot and put labels and notes in there. Could you recommend a tool to easily accomplish that goal with easily. I guess it can be done with any of those as seen by the demos [2][3]. I only have little experience using Gnuplot and I have never used Asymptote or MetaFun. These three seem to be well integrated with ConTeXt and I guess in the end I could just create the image files and include these in to my ConTeXt source. The only downside of Asymptote I found so far is, that there is no mailing list.

These three seem to be well integrated with ConTeXt and I guess in the end I could just create the image files and include these in to my ConTeXt source. If you don't mind using external figures, I personally would recommend matplotlib (as used to create the example you linked to) -- in which case you already have an example script for your graph :-). The annotation and labelling facilities are extensive (see http://matplotlib.sourceforge.net/examples/pylab_examples/annotation_demo2.html ) and there is ample documentation. I used to be a happy Gnuplot user, but I find that with matplotlib the easy things are just as easy, the hard things are easier, and some of the impossible things become possible. I did give MetaFun a try before turning to matplotlib, but I found it quite difficult to work with. That's strictly related to my personal requirements and taste though -- there are many satisfied MetaFun users on this list (and thus good support) and of course it is very well integrated with ConTeXt. Asymptote looks nice but I've never tried it. I think there have been some issues with ConTeXt integration in the past (see http://thread.gmane.org/gmane.comp.tex.context/54389 ) but am unsure of the current state.

The only downside of Asymptote I found so far is, that there is no mailing list. Below you have an example done in metapost/metafun (which integrates well with ConTeXt). The downside of metapost is that you have to do all the labels and axis drawing more or less manually, while gnuplot will take care of drawing axes and properly adjusting the range etc. On the other hand metapost might be quite powerful for geometrically complex graphics. If you use gnuplot, you might need to precompute the points for the random walk (it supports random numbers, but I'm not sure if you can calculate sums), while metapost can do some reasonable calculations on the fly. For 2D graphics asymptote doesn't bring you much. Yet another alternative is TikZ and pgfplots (similar to metapost, more library functions ready to draw all kinds of graphics, but less powerful math engine that in metapost). \setupcolors [state=start] \starttext \startMPpage save wx, wy; wx = 15cm; wy = 10cm; draw unitsquare shifted (0,-0.5) xyscaled (wx,wy); save val; numeric val; save tmp; numeric tmp; save p; path p; save c; color c[]; c[1] = red; c[2] = .5[red,yellow]; c[3] = .6green; c[4] = blue; c[5] = .4white; vardef newval = val := val + floor(uniformdeviate(2))*2-1; (val) enddef; for n=1 upto 5: val := 0; draw (0,0) for i=0 upto 100: -- (0.01*i*wx,0.025*newval*wy) endfor withcolor c[n]; endfor for i=0 step 20 until 100: label.bot(decimal(i), (0.01*i*wx,-.5*wy)); endfor; for i=-20 step 5 until 20: label.lft(decimal(i), (0,0.025*i*wy)); endfor; \stopMPpage \stoptext ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

[NTG-context] rules with different thickness
Hi I stumbled upon this while making a table with rules, where I wanted to have a particular row highlighted with a thicker border: http://www.mail-archive.com/ntg-context@ntg.nl/msg33678.html Since this was posted more then two years ago, I just wanted to know if anything changed on this front? Having r|l|t|b-offsets I thought I could use the same for rulethickness, but according to this, not yet. The metapost workaround works still fine, so for now I'm using that, just want to know what's the status on this.

Do you have “\enabledirectives[schemes.cleanmethod=md5]” in your preamble?

No, there is only one value for all four borders.

It’s the same as in the past, use MetaPost but there are better ways to change
values of certain borders:

\setupTABLE
