Matthias' reply is better for your situation, but for curiosity's sake, here is what actually happens: - MetaPost is happily reading MetaPost commands when suddenly it sees a btex command. - Now it will throw away everything upto the next etex, and it will run the external command makempx with the current filename as argument. * makempx's goal is to create a file with the same name as it's argument, but with the extension replaced with .mpx. That file will contain a series of low-level MetaPost commands for each label in the source file, and those lists of commands are separated by the MetaPost command mpxbreak. * nothing is done by makempx if the mpx file exists and is newer than the source file. ** otherwise, the source file is scanned for verbatimtex ... etex and btex ... etex blocks. These are wrapped in very simple TeX macros and written to a TeX input file. ** TeX is run, to produce a DVI file from these commands (each dvi page representing a label) ** The entire DVI file is then converted into the .mpx file in a single action. - MetaPost will now open the .mpx file as a concurrent source of commands linked to the current source file, and read commands from it up to the first mpxbreak. - The location pointer in the .mpx file is saved for subsequent labels.

[NTG-context] Referencing eqalignno-formulas, and some more
Hello,
I started using context recently and have encountered
some difficulties where I need some help to get over.
(1) References in math formulas:
\placeformula [Ref]
\startformula
\eqalignno {
...
}
\stopformula
It seems that referencing to '\eqalignno'-formulas
needs some tricks. Is there any (non-)documented way
to attach a reference to a line inside '\eqalignno'
multiline formula? E.g. a mechanism like \xxx[Ref]
\eqalignno {
...
f(x) = x^n - 1\xxx[Ref] \cr
...
}
so one can point to \in{formula}[Ref] and get the
correct reference number subsituted?
(2) Left/right margins of different width in doublesided
layout: I invented my favorite layout as in
\setuplayout [location={doublesided,duplex}, marking=off,
top=6mm, topdistance=6mm, bottom=6mm, bottomdistance=18mm,
topspace=18mm,
height=243mm,
header=6mm, headerdistance=6mm,
footer=6mm, footerdistance=18mm,
backspace=46mm,
width=124mm,
leftmargin=12mm, leftmargindistance=4mm,
leftedge=2mm, leftedgedistance=2mm,
rightmargin=28mm, rightmargindistance=4mm,
rightedge=6mm, rightedgedistance=2mm
]
\setuppapersize [A4][A4]
\setuppagenumbering [style=normal, alternative=doublesided,
location={footer,middle}]
\showframe
and if '\showframe' is active I can verify by ruler that
all distances and measures etc. are drawn correctly
according to both sides of the printed sheet.
(Though it remains to be investigated why only
'backspace=46mm' gives 26mm whitespace at the left paper
edge, i.e. the distance from the left paper edge to the
left edge of the 'leftedge'.) :-)
Putting \inmargin{Some text} on evennumbered
pages (in a doublesided setup) shows margin area width as
in 'leftmargin' in '\setuplayout'; shouldn't it adapt
itself according to doublesided layout as the margin
frame does in '\showframe'?
(3) Math formulas in footnotes result in
Math formula deleted: Insufficient symbol fonts.
I have the same style for margins and footnotes
(I hope the following setup does this as was my
intention),
\setupfootnotes [style=\tfx\setupinterlinespace]
\setupinmargin [style=\tfx\setupinterlinespace, align=right]
and in typesetting formulas in margins this error doesn't
occur, i.e. there are sufficient symbol fonts available
(whatever it means) :-)
I am using Adobe Utopia text with Palatino math fonts.
(4) HZ-algorithm. This, as well as metafun positional graphics
and metapost color transparency, was the reason I started
trying out context. My understanding is, HZ gets activated
not with
\font\tenrm=cmr10 at 10pt stretch 30 shrink 20 step 10
as documented in 'pre-hz.pdf' at PRAGMA-ADE but using
\pdffontexpand\tenrm 30 20 10 1000
as I noticed somewhere. The question is, are *.tfm files
like
cmr10-20.tfm
cmr10-10.tfm
cmr10+10.tfm
cmr10+20.tfm
cmr10+30.tfm
enough to get it going, and can be generated manually
from *.afm files using 'afm2tfm'?
Though, '\pdffontexpand\tenrm 30 20 10 1000' results in
Missing font identifier. in context... :-)
I am using Context 2003.1.31 with pdfetex 1.10a-2.1 as
in tetex 2.0.1 distributed in SuSE Linux 8.2.
Thanks in advance for any help, item (1) is most
critical, though.

This should work ok. Try
\placeformula[ref]
\startformula\eqalignno{
a = b \formulanumber[refa]{a}\cr
b =c \subformulanumber[refb]{b}\cr
}\stopformula
\in[ref], \in[refa], \in[refb]
or
\placeformula
\startformula\eqalignno{
a = b \formulanumber[ref1]\cr
b =c \formulanumber[ref2]\cr
}\stopformula
\in[ref1], \in[ref2]

On Mon, Aug 23, 2004 at 01:26:06AM +0200, Hans Hagen Outside wrote: ok; btw, also take a look at sieps afm2pl since it has some other nice features Hans My belated three cents on some of the things which were discussed in this thread: As to texnansi: this is supported in Latex by texnansi.sty. For Western European languages, it seems to cover pretty much everything, so there is no need for text companion fonts or virtual fonts. Basic support (without artificial smallcaps) for a font family with non-virtual texnansi fonts consists of just four tfms, a mapfile fragment and, for Latex, an fd file. As to fontinst: doing it the easy way, using just the latinfamily command, you get dozens of files, in 8R, T1, OT1 and TS1 encoding. You have to be pretty expert if you want more fine-grained control and a more economical set of support files. I don't even know whether Fontinst can generate non-virtual texnansi fonts which are suitable for regular typesetting. Besides, I believe that nowadays fontinst depends on Latex. Sorry about just mentioning Latex here: I am only an occasional Context user, and don't use typescripts or texfont at all. As to afm2pl: the latest version available from tex.aanhet.net is 0.6; later versions are written to be part of TeX Live 2004 which is currently under development. Because of changes in the TDS, these may not work correctly in an older TeX installation. Version 0.7.02 with afm2tfm compatibility is not yet in the TeX Live source tree, last time I checked. -- Siep Kroonenberg ___ ntg-context mailing list [EMAIL PROTECTED] http://www.ntg.nl/mailman/listinfo/ntg-context

[NTG-context] Footnotes in margin (again)
Hi,
as the dust has settled over the ancient greeks I would like to re-ask a posting that
is about another quite crucial question: How to place footnotes in the margin?
Every time I turn on \showframe I think that the margin is such a beautiful place for
placing footnotes (per page, flushbottom). There must be a way!
Isn't there a way, Hans?

Hi,
does ConTeXt provide a way to place footnote (not margin notes!) per page - but not
below the body text?
A suitable place could be the margin. But there is no
\setupfootnotes[location=inmargin]
and somthing like \inmargin{\footnote{}The footnote's text.} doesn't flow.
Does anybody know a working solution?
Thank you,
Steffen Wolfrum
