[NTG-context] Linebreak in Metapost/Metafun Label

Thanks Aditya. Sorry but that does not work. The text line just starts shifting
to the left for me. It spills outside the frame.
I tried with both MKIV and MKII. The MKIV version I tried with is
ConTeXt ver: 2009.03.18 21:58 MKIV
Any ideas why it may not be working for me?
Thanks.

Awesome! That works great. Before asking I tried searching a lot in metafun
manual and on the web but could not find anything. I am not yet clear about the
logic. When I saw that I could color labels using the \color[red]{red} command
by putting it between btex...etex, it seemed to me that any context command
would work if put in there. So I tried \crlf to get a linebreak and that did not
work. So I thought maybe only very few specific commands work. Now after seeing
your solution, again I am wondering, what determines which commands work and
which do not. Anyhow, I am not asking for an explanation, because it will most
probably beyond me and may be a long one for someone to explain. But I
appreciate the solution.
Thanks again.

Here is a simplified picture. Basically, anything inside btex ... etex (or
textext(...) or \sometxt{...}) is in what is known as TeX's horizontal
mode. Think of this as what you will get if you put the same argument in a
\hbox (see the TeXbook or TeX for the impatient for details). To get
multiple lines you need tex to be in the vertical mode, a \vbox. A vanilla
\framed is like a \hbox. Framed with align=normal is like a \vbox. So, for
most purposes you can you \framed. There are some commands that need to
know the width of the box (like \start stop formula). In those cases you
need to specify width=something to \framed.
Of course, certain objects like floats, footnotes, marginpars, will never
work inside metapost. (I think you can get floats and footnotes to work,
but that will require some hackery)

Thanks very much for the explanation. Now I understand much better. I remember
reading about the importance of horizontal mode and vertical mode in the Seroul
and Levy's book I think.

[NTG-context] mplib/metafun broken in latest beta
Hi Hans and Taco,
it looks like mplib is broken in the latest beta. Simple file:
\starttext
\startuseMPgraphic{test}
draw fullcircle scaled 5cm ;
\stopuseMPgraphic
\useMPgraphic{test}
\stoptext
produces no output. I tested on several different computers, so it
doesn't look like a misconfiguration. My Macbook compiled the file
fine with a context version from last week; after updating, a get an
empty pdf.
All best
Thomas

could you wrap this into a macro to define different commands
for marginstuff, could be usefull to write margintexts for more

Pretty cool! I knew ConTeXt can do it and thank you Hans

Hi Arthur, I'm suffering a network problem so sometimes

[NTG-context] Weird behavior about metafun
Hi Hans and Wolfgang, I'm just trying to make some illustrations about the Chinese typesetting features. So I choose the way which is described in Chapter 5 of the metafun manual. And I wanna draw a line from the text I wanna comment on to the marginal notes which my comments lay on. To highlight them, I drew an underline below the contexts which is to be commented and put a square around the comments. Everything is under control except I put \fpos and \tpos around the comments, the framed box is not exactly what I want. It seems that metafun still thought it's in the main text so it drew the bounding around the body. I found the mpos:par was defined in core-pgr.tex and it used show_par or draw_par which are defined in mp-core.mp. I don't think it's a good way to define another MPpositiongraphic called like mpos:marginpar to match my case. Do you think it's possible to change some of the core codes to make metafun recognize where she is. -- Best Regards Chen Zhi-chu Chen | Shanghai Synchrotron Radiation Facility No. 2019 | Jialuo Rd. | Jiading | Shanghai | P.R.

no, that could happen in the macro that uses \fpos, not in \fpos itself

Or, I could imagine that you should be able to defne some commant, so that
\sometxt[mathml]{..mathml stuff/..} could work out of the box.
See
http://dl.contextgarden.net/myway/sometxt.pdf
However, I have never played with mathml, so you should try it out and
report if there will be any problems.

Hi Oliver,
see
http://wiki.contextgarden.net/Mpgraphic#.5CstartMPenvironment
You can use one of the options [global|+|reset].
'global' and '+' are also setting the env in the main doc (one font def
for all), 'reset' brings the environment back to it's defaults (s.
meta-ini.tex).
Best wishes, Peter

the boundingbox sets the final size of the gfx. if your gfx is larger

There's one solutions which is far better faster more efficient

[NTG-context] frames in ConTeXt and metafun
This is a very small cosmetic problem, but it bugs me: I'm preparing
a background for a presentation, and I want a frame with a
transparent color to appear on every slide, so I define an overlay
and use metapost. I also want to frame some text elements, so I use a
\framed. The problem is that in the \framed, the lines of the frame
overlap at the edges, so with a transparent color, the corners are
slightly darker. The minimal example below shows the problem. Any
solution? Is it possible to have the frame around \framed drawn by
metapost?
Thanks!

Hi,
right, the object=no value is the problem. You can solve your problem
by inserting the following macro somewhere before starttext in your
document:

{\ifx\undefined\externalfigure
\message{[insert file #1 here]}%
\else
\externalfigure

\protect
I changed only the no value from object to yes.

[NTG-context] Fonts, nice looking headers, MetaFun and CV module
Hi.
I'm been huffing and puffing the last few days trying to do my CV in
ConTeXt. My previous version used the LaTeX Curve package and I was
pretty happy with that.
I'm learning alot by doing this myself but some things have been pretty
hard. The hardest: trying to some kind of fancy section headers. I'm
pretty sure I should have been able to do this with the available
documentation but I've read and read and not been able to find a
solution.
Here's some of the things that my little brain can't comprehend:
1. I'm thoroughly confused about how fonts work. From various
documents I found some that worked, for example:
\definetypeface [zapf] [cg] [calligraphy] [chancery]
\switchtotypeface [zapf] [12pt,cg]
or
\setupbodyfont[ber,pos]
But I can't seem to find any place that lists the fonts I can use or
how this actually works. Is there any standardized way, for example,
to change font in headers or definitions of commands to affect only
text in those definitions?
2. Fancy header with half of the text in background color (see headers
in my former pdf at http://www.vitum.net/gjk/cv.pdf).
I tried various things here. Using \framed, MetaFun and \setupbackground.
For example:
\setupbackground
[leftoffset=0.3cm,
rightoffset=0.3cm
topoffset=-0.5cm,
bottomoffset=0.3cm,
background=color,
backgroundcolor=red]
I guess I'm misunderstanding the offset parameters.
3. Framed texts with titles:
As explained in the MetaFun manual (Section 4.6, page 236) I tried
using the code in that section...
\FrameTitle{Zapf (1)}
\StartFrame
Coming back to the use of typefaces in electronic
publishing: many of the new typographers receive their
knowledge and information about the rules of typography from
books, from computer magazines or the instruction manuals
which they get with the purchase of a PC or software.
\StopFrame
\startuseMPgraphic{FunnyFrame}
picture p ; numeric w, h, o ;
p := textext.rt(\MPstring{FunnyFrame}) ;
w := OverlayWidth ; h := OverlayHeight ; o := BodyFontSize ;
p := p shifted (2o,h-ypart center p) ; draw p ;
drawoptions (withpen pencircle scaled 1pt withcolor .625red) ;
draw (2o,h)--(0,h)--(0,0)--(w,0)--(w,h)--(xpart urcorner p,h) ;
draw boundingbox p ;
setbounds currentpicture to unitsquare xyscaled(w,h) ;
\stopuseMPgraphic
defineoverlay[FunnyFrame][\useMPgraphic{FunnyFrame}]
defineframedtext[FunnyText][frame=off,background=FunnyFrame]
\def\StartFrame{\startFunnyText}
\def\StopFrame {\stopFunnyText }
\def\FrameTitle#1%
{\setMPtext{FunnyFrame}{\hbox spread 1em{\hss\strut#1\hss}}}
\setMPtext{FunnyFrame}{} % initialize the text variable
...and I have the following problems:
- The framing of the text is limited to a too narrow textwidth. I can't
seem to find where I change that in the code.
- Icelandic letters don't seem to work in titles or the text in the
frames. They do work in other places in the document, though.
Phew, that's enough for now. If any of you guys/gals have other ideas on
how to do nice looking headers I'm open to everything.
Btw, I love using ConTeXt and really appreciate all your hard work.
P.S. Is there any CV package for ConTeXt out there? If not I could post
my work (if people like what I did) to the ConTeXt wiki for others to use.

[NTG-context] metafun: verbatimtex coming too late?
In this file, I intended that all labels would come out in 7pt:
=== cut here
\starttext
\startMPenvironment
\setupbodyfont[7pt]
\stopMPenvironment
\startMPinclusions
def drawtext =
label(btex In drawtext() macro. etex, origin);
enddef;
\stopMPinclusions
\startstaticMPfigure{fig}
drawtext;
label(btex Inline in the figure. etex, (2in,0));
\stopstaticMPfigure
hello, in 12pt, for comparison.
\placefigure[force,none]{}{\usestaticMPfigure[fig]}
\stoptext
=== cut here
However, only the label that is directly in the figure (Inline in the
figure.) comes out in 7pt. The other one, produced by the drawtext
macro, comes out in 12pt. The resulting metapost file is file-fig.mp
and the key portions are (with spacing adjusted a bit):
def drawtext =
label(btex In drawtext() macro. etex, origin);
enddef;
beginfig(1);
verbatimtex \global \loadfontfileoncetrue \setupbodyfont [7pt] etex;
drawtext;
label(btex Inline in the figure. etex, (2in,0));
endfig;
The verbatimtex..etex block inside the beginfig..endfig doesn't affect
the btex..etex in the drawtext macro, I guess because drawtext is
defined outside of the beginfig..endfig.
This is all with context 2006.08.08. I tested it on the live context,
but the transcript says figure texweb-fig.pdf can not be found.
A possible solution is to put the verbatimtex at the beginning of the mp
file or after the input mp-grph, making it like this:
verbatimtex \global \loadfontfileoncetrue \setupbodyfont [7pt] etex;
def drawtext =
label(btex In drawtext() macro. etex, origin);
enddef;
beginfig(1);
drawtext;
label(btex Inline in the figure. etex, (2in,0));
endfig;
but does that break other assumptions?
Another solution is textext instead of btex..etex, though I don't
understand the differences between the two. The main one: textext
expands the tex commands in its argument whereas btex..etex does not.
But in regular metapost btex..etex does expand, so I'm confused a bit.
For example, you can do mpost file.mp with file.mp being
verbatimtex \def\M{{\rm M}} etex
beginfig(1)
label (btex mass $\M$ etex, origin);
endfig;
end

[Hans: Feature suggestion for figure inclusion at the end...]
I wrote:
So, is --final a requirement when using metafun, or am I hacking

An answer is that I should set \runMPgraphicstrue. I thought it was
automatically set, half-remembering what Aditya said in the previous
thread on metafun. So the following works (changing the r changes the
result right away without requiring --final or requiring two texexec
runs):

To see where and when \runMPgraphicstrue was done, I looked into the
metafun interface code, and asked grep for help:
$ grep '\\runMPgraphicstrue' *.tex

supp-mps.tex:1653:%D \global\runMPgraphicstrue
supp-mps.tex:1991: \runMPgraphicstrue
So it's commented-in only at line 1991, which is part of a new (to me)
method of figure inclusion: \startstaticMPgraphic, which says
Dedicated to Aditya Mahajan. See meta-ini for usage, so I see how
Aditya would conclude that \runMPgraphicstrue is always true :-)
The following therefore also works to get instant updating, and is
more efficient than reusable MP graphics in that it reruns metapost on
included figures only when they change:

Which I just now see is on the Wiki page about metafun (I'd been
working from the excellent metafun manual).
It's doubly smart in that changing the papersize (which changes the
layout parameters, which are included in the metapost file) will rerun
the graphic, even if r stays the same. So the graphic can base itself
on those parameters and be updated when needed.
Thanks, Hans and Aditya!
While experimenting with the methods of figure inclusion, I've been
changing among \reuseMPgraphic, \usestaticMPfigure, \useMPgraphic, and
\externalfigure to call up the figure. Do all the figure labels live
in the same namespace? In which case (warning: feature suggestion!)
when they are defined, e.g. with \useexternalfigure,
\startstaticMPfigure, ..., could the label have associated with it the
command that calls it up? So one could do for all types:
\usefigure[thelabel]
and ConTeXt would figure out what kind of figure it is and turn
\usefigure into the appropriate one (\reuseMPgraphic, ...).
Then speaking purely hypothetically of course: If, after learning
metafun, one decides to turn many external metapost figures into
metafun figures (and then static figures instead of reusable figures),
the figure placement commands don't have change.

[NTG-context] transparent metafun colors turn nearly black
Just for (meta)fun, I tried a few experiments with transparent colors.
The example below gives a black circle instead of a red one. Is it that
transparent colors aren't part of metafun -- which I can easily live
with since color printing is too expensive still, alas -- or have I
omitted an essential command?
cut here
\runMPgraphicstrue
\setupcolors[state=start]
\starttext
\startreusableMPgraphic{a}
% _inline_specials_ := true; % had hopes for this line, but no luck
% next line taken as an example from mp-spec.mp
fill fullcircle scaled 10cm withcolor transparent(8,.3,red);
\stopreusableMPgraphic
\placefigure[force,none]{}{\reuseMPgraphic{a}}
\stoptext
cut here
The metapost output (testfile-mpgraph.1) always contains the following
color setting, no matter what arguments I pass to transparent() :
0.123 0.003 0.001 setrgbcolor
Which is close to black.
(This is all with ConTeXt 2006.08.08. The live ConTeXt gives a square
saying undefined.)

I also tried the old perl texexec in case that helped but no luck.
The texexec log on contextgarden looks okay. It generates
texexec-mpgraph.1 and embeds one figure, so I'm guessing the figure is
generated and inserted. So I don't understand why the generated PDF
file is not right. To make sure it wasn't a caching problem, I added
a bit of text to the end, to see whether the new PDF file had it (it
did).

Hi, This all sounds like the 'missing specials' problem that is caused by conflicting -progname= arguments when using the web2c version of metapost. Make sure you do not have conflicting memory settings for both main_memory.mpost as well as main_memory.metafun The best is to remove all trace of '.mpost' and '.metafun' memory settings from your texmf.cnf, but at least make sure all the '.mpost' and 'metafun' values are the same . Then regenerate metafun using texexec --make, and all should be well again. Cheers, Taco ___ ntg-context mailing list ntg-context@ntg.nl http://www.ntg.nl/mailman/listinfo/ntg-context
Re: [NTG-context] transparent metafun colors turn nearly black
These were the memory setting in the /etc/texmf/texmf.d/95NonPath.cnf configlet that is part of Debian and Ubuntu: main_memory = 100 % words of inimemory available; also applies to inimfmp main_memory.context = 150 main_memory.mpost = 150 I commented out the .mpost line (there was no separate metafun line, which I guess was getting the main_memory value of 100), regenerated the texmf.cnf with update-texmf, then regenerated metafun with texexec --make metafun and transparency worked. So thanks for the magic! Have wikified the above in case anyone else runs into it http://wiki.contextgarden.net/Mpgraphic.

[NTG-context] does metafun require texexec --final?
I was trying experiments with the file below, changing r from 1cm to
10cm or vice versa, then rerunning texexec and looking at the pdf. But
the pdf changes only the second time that I run texexec (and each time,
texexec runs metafun for the embedded graphic). However, the pdf
changes right away if I give --final to texexec.
So, is --final a requirement when using metafun, or am I hacking around
a problem I've caused by leaving something out?
Oh, having heeded Aditya's earlier advice on the list: \write18 is
enabled.

Ok, I looked into this again, and I was definately wrong.
The actual problem appears to be that metapost does not write a
color switch for 'black' when it appears at the start of a file,
it simply assumes the start color is black. This could be
considered a bug in MetaPost or a missing feature in ConTeXt
(i have not decided yet :-)).
Quick fix: You can start your MP code with an explicit color
initialization.
\startMPcode
special 0 setgray;
..
\stopMPcode
A hack, I know. MetaPost should be able to distinguish between
draw p
and
draw p withcolor (0,0,0)
but currently it can't (because the structure is initialized
as (0,0,0)). It is not quite a bug either, because there may
well be MP code out there that depends on this.
In fact, probably code by Knuth, Hobby, Jacko, and Hans ;-)
in meta-pdf.tex:
\chardef\blackoutMPgraphic\plusone
\def\finishMPgraphic
{\stopMPresources
\egroup
\setbox\scratchbox\vbox
{\forgetall
\hbox
{\PDFcode{q \MPxscale\space 0 0 \MPyscale\space \MPxoffset\space
\MPyoffset\space cm}%
\ifcase\blackoutMPgraphic\or\PDFcode{0 g 0 G}\fi
\lower\MPyshift\box\scratchbox % unscaled shift
\PDFcode{Q}}}%
\ht\scratchbox\MPheight
\wd\scratchbox\MPwidth
\dp\scratchbox\zeropoint\relax
\dopackageMPgraphic\scratchbox
\egroup
\endinput}
\starttext
\color[red]{\startMPcode
draw fullcircle scaled 5cm ;
draw btex test etex ;
\stopMPcode red}
\startreusableMPgraphic{test}
draw fullcircle scaled 5cm ;
draw btex test etex ;
\stopreusableMPgraphic
\color[red]{red \reuseMPgraphic{test} red}
\stoptext
Thanks! This indeed solves the problem. However, I'm not sure any more
whether blackoutMPgraphic should be true or false by default.
One of my old files (when I was learning metapost from the manual):
def star (expr size, n, pos) =
for a=0 step 360/n until round(360*(1-1/n)) :
draw (origin -- (size/2,0))
rotatedaround (origin,a) shifted pos ;
endfor ;
enddef ;
beginfig(803) ;
pickup pencircle scaled 2mm ; star(2cm,5,origin) ;
endfig ;
\useexternalfigure[pentastar][star.803][height=4cm]
\starttext
\placefigure
{A five||point star drawn by \METAPOST.}
{\color[green]{\externalfigure[pentastar]}} % I wanted it to be green
\stoptext
I tried that one once more because I remember that I was very happy to
be able to color the star from outside without modifying the figure
itself (I didn't use any explicit color to make it black though).
I don't mind it either way (now that I know how to switch it on or
off), but I'm not sure if there are not other people using the same
trick as well.
The real problem appears in the following figure where the first
black is ignored and the second one is not, so it's rather
inconsistent:
\setupcolors
[state=start,textcolor=blue]
\chardef\blackoutMPgraphic 0
\starttext
\startMPcode
draw \sometxt{blue} withcolor black;
draw \sometxt{red} shifted (1.5cm,0) withcolor red;
draw \sometxt{black} shifted (3cm,0) withcolor black;
\stopMPcode
\stoptext
I can image a fair solution to draw withcolor black in black and
to let the parts with no explicit color and an empty drawoptions()
string to use the default color (perhaps with gsave/grestore). But
I'm not entitled to judge about it.
In any case I'll have to use a solution which will not depend on this
behaviour. Is there any chance to get withcolor somecolor, where
somecolor is the color set with textcolor=somecolor?
Thanks a lot,
Mojca

It is not really inconsistent, the rule is very simple:
all use of withcolor black upto the first non-zero color
is ignored by metapost.
OK, I give up. I just have to reimplement the terminal to fist store
everything and then write out the black stuff before anything else ;)

Yes, that's what I thought. But I need to patch metapost for
that, so that solution won't be available in a reliable way
for quite some time yet.
I realise that and I'll try to implement in an independant way.

Maybe withcolor \MPcolor{textcolor} ? (I am guessing)
Something that seems to work after some trial-and-error:
\definecolor[textcolor][\@@cltextcolor]
But I'm guessing as well. Let's wait for the next bug in the module then ;)
I now used
\definecolor[textcolor][\@@cltextcolor]
% \MPextensions, should be specific to \startGNUPLOTgraphic
\startMPextensions
if unknown context_gplot: input mp-gnuplot.mp ; fi;
% overloading
gp_color_foreground := \MPcolor{textcolor};
gp_color_lt[-2] := gp_color_foreground;
\stopMPextensions
(because there's probably no way to put \MPcolor{textcolor} to *.mp file)
But now there's a minor problem. I have to initialize
\setupcolors[textcolor=blue] *before* loading the gnuplot module,
otherwise it's all black.
In contrast, if I use
\setupcolors[state=start,textcolor=blue]
\usemodule[gnuplot]
a graphic here will be blue
\setupcolors[textcolor=red]
a graphic here will be red, but text will still be blue
And
\usemodule[gnuplot]
\setupcolors[state=start,textcolor=blue]
a graphic here will be black
\setupcolors[textcolor=red]
a graphic here will be black, but text will still be blue
I suspect what's going on: as long as textcolor= is undefined,
\@@cltextcolor will expand to black and remain black even if I set
textcolor=something later. If it's initialised before loading the
module, it will expand to some color and if I change
textcolor=someothercolor later, the color will follow the new
definition.
What's the best remedy for it? (And sorry for way too many questions.)
Thanks,
Mojca
