Re: [NTG-context] beginners manual
Hans, Taco, et al, It's time for me to wax philosophic on the beginner's manual. I've read a few posts to this list, and tried to think back to my experience, and looked at my troubles now, but I haven't reread the beginner's manual as yet. That I will do in the upcoming weeks. My first thought is this: In my opinion, the beginner's manual remains one of very best sources for Context. My second thought is the fact that this is a beginner's manual in every sense of the word. That is, you need to be very careful with what goes into the manual. Truly, a guiding principle should be: What does a beginner need to see? Think of a user who is beginning with a blank slate, or alternatively, think of a user who's been gone for a while (I've qualified for this category on several occasions and revisiting the beginner's manual has always been helpful). What does this user need to see? And what does this user need to be protected from? First and foremost, you've got to make sure that users on different platforms have a good install of Context. This could be a set of appendices: Appendix A -- Installation on Windows, Appendix B -- Installation on Linux, Appendix C -- Installation on Mac OS. Again, users could be very helpful in testing these instructions. This is a beginner's manual, so it would be helpful if these instructions were of the Quick Start variety, as involved instructions will only serve to frustrate the beginner. Of course, these instructions should include a Hello, World! example in order to test for a valid installation. Whenever I teach a new concept in mathematics, I'm faced with a choice of two directions. I can start with the concept, then give examples. Or I can do some examples, then discuss the abstraction at a higher level. I am constantly forgetting that the second method is usually a better choice for my students. For example, suppose that I want to show that any multiple of an eigenvector is again an eigenvector of a given matrix. I can first prove it in the abstract (A (cx)=c(Ax)=c(lx)=l(cx)), then give examples. Alternatively, I can put a little 2x2 matrix on the board, find the eigenvectors, then demonstrate that multiples of the eigenvectors are again eigenvectors. Once the students have the idea, then I can put up the abstraction of the general proof. A reference manual is an example of the first method, a beginner's manual should follow the second method. It's easier, in my opinion, to learn by example, to learn by doing. Topics should be included or excluded based on a guiding principle: What does a beginner need to know to get started? It will be tempting to include using a different font, or talk about interactive documents, etc, but these are advanced topics, which belong in separate manuals where space and time will do them justice. Indeed, what is truly needed is a separate beginner's manual on interactive documents. Layout really threw me for a loss the first time (and times thereafter) I went through the beginner's manual. I was confronted with terms (cutspace, backspace) that might be familiar to typographers, but I had no clue what they meant. I can remember spending countless hours tweaking layout parameters, printing, then measuring with a ruler, only to scratch my head when I did not get predicted results. To this day, I am still not completely sure what I am doing in this area. I think what is needed in the beginner's manual is an image similar to Patrick's \ShowLayout result from his t- layout module. Secondly, it would be time well spent to build an improved \showframe command. Perhaps this even exists, but I am not aware of it. It needs to provide accurate measurements, even when printed and the rulers come out. Perhaps if a user included the \showframe command, a trigger of some sort could change the size of the paper that the document is typeset on, with an outline of the actual paper size, and the edges, margins, headers, etc, all framed and in view, even if they lie outside the actual paper outline. List users can help to make sure that the manual is free of errors. If something doesn't work, this is much more upsetting to a beginner than a seasoned user. A seasoned user might say oh, that's just a typo, do this, but a beginner has an entirely different reaction on an entirely different emotional level. Troubleshooting should get some time in the beginner's manual. People coming from a Word environment are not going to understand what is going on when a compilation halts. Seasoned TeX users know about typing h, x, s, e, etc, but people who've never seen TeX before are going to freak out. So, some time should be spent on troubleshooting. Or, a conscious decision has to be made: Will we assume that all beginners in Context have TeX experience? So, I advise, stick to the basics. Get the user started. Ask yourself

[NTG-context] Moving close to Lucida but still not there
Hans, Taco, Adam et al, I dropped all of my lucida pfb and afm fonts into a temporary directory, ~/tmp/lucida.

Getting texfont to do batch installs on gwTeX (was Re: [NTG-context] Palatino)
David, Sorry I've been quiet on this front. I've been busy with other, non- ConTeXt things for a while, and am in the process of re-engaging with it. In order to run type-tmf.dat, you need a way around the hard-coded -- rootlist=TEXMFMAIN that's in the .dat file. gwTeX keeps the fonts we need in what it calls the TEXMFTE directory. My brutish workaround is as follows: 1) Go to some temp directory. 2) copy type-tmf into that directory: cp /usr/local/teTeX/share/texmf.local/context/data/type-tmf.dat . 3) munge type-tmf to something more gwTeX friendly: sed s/TEXMFMAIN/TEXMFTE/ type-tmf.dat type-tmf-gw.dat (literally: replace every occurrence of TEXMFMAIN with TEXMFTE and put it in type-tmf-gw.dat) 4) run texfont (prepend with sudo if you have errors): texfont type-tmf-gw.dat 5) run it again, if you want the ec encoding: texfont --en=ec type-tmf-gw.dat 6) process one or two test files to see if it really worked: texexec --once --mode=compact texnansi-urw-bookman.tex I hope that works for you. Gerben, Hans, can you think of a way to make this workaround unnecessary? adam David Arnold said this at Tue, 22 Nov 2005 09:08:17 -0800: Hans, When I try: 011-101:/usr/local/teTeX/share/texmf.local/context/data davidarnold$ sudo texfont --encoding=texnansi -batch type-tmf.dat I get a slew of messages similar to this last one: TeXFont 2.2.1 - ConTeXt / PRAGMA ADE 2000-2004 slant factor : 0.167 checking root : TEXMFMAIN processing aborted : unknown subpath ../fonts/afm/urw/ncntrsbk --help : show some more info Some extra information: texexec --verbose reports: applications will use : /usr/local/teTeX/texmf.cnf This last file is attached.

Re: [NTG-context] Mini-survey: What do you do with ConTeXt?
Taco, Hans— One of the key features of ConTeXt for me is its ability to create platform independent output that combines the ancient languages and mathematics in ways typical of publications in the humanities. So, first, my heartiest thanks to you both and also to Thomas Schmitz for his Greek module. I currently use ConTeXt to publish the Institute’s review/journal (which is available online, in print, and on CD), as well as its brochures and announcements. I will also be using it to produce its books too. I have designed a book publication series for my brother using ConTeXt; and I use it to write my own papers, reviews, and books. The main problem that I have is not really with ConTeXt itself. Since few of the history of science journals that I send papers to use ConTeXt, I am often required to I submit an .rtf file along with the .pdf file produced with ConTeXt. So, what I am still contemplating is an efficient, “mechanical” way around this problem.

Re: [NTG-context] ConTeXt to RTF Conversion
Dear gang, I have followed this discussion with interest. I edit a journal myself. Despite announcing loudly that it is TeX-friendly, the only person who writes articles in TeX for it is, you guessed it, myself. I know next-to-nothing about xml, so I apologize if the next question is ignorant: Would it be possible to define an xml format for the journal so that I could more easily process both ConTeXt/LaTeX articles as well as the docs and rtfs I generally receive? Is this more work than it's worth? It's a humanities journal, so little-to-no math.

TeX has simply never been written to be easily parsed. Besides, our actual users are way too much concerned with what their stuff looks like on their screens with their settings to bother about structured information and the like. Believe me, I have almost finished the translation of our highly structured program documentation files to some DocBook-based XML format, and I am very happy that I had decided to make this a one-time conversion with the automated process only trying to get some 95% or so correct. My experience with the new format (which is still limited, I've been working with it the last four months or so) leads me to believe that it is no more difficult to use than some TeX dialect. The only slightly awkward thing is that you have to explicitly mark all paragraphs. I don't mind, but if you do, that sort of thing can be scripted. Short summary: Define an xml format that embeds what you need at the moment. One mistake I made: I didn't go for short names, but used DocBook names. I probably should have started from XHTML, using p, em, a etc. Then use that format as your master and edit in this format. There are magnitudes more decent editors to help you with editing all sorts of xml than you will ever find for any TeX variant. (I know, one is sufficient, but finding one that does exactly what *you* want is much easier with more editors to choose from.) So my question was, is there any exeprience about the use of the ConTeXt module m-tex4ht? I do have experience with using tex4ht in LaTeX, which is its native setting. It is definitely much better than all the alternatives I tried, but it does have problems with formulas, it is rather difficult to teach it your new local commands and the generated HTML code is usable for exactly one thing: Rendering in a graphical browser, for us lucky ones without visual impairments. I would not dream of using this pile of mess for anything else. HTML generated by Word simply can't be worse. regards, Christopher ___ ntg-context mailing list ntg-context@ntg.nl http://www.ntg.nl/mailman/listinfo/ntg-context
[NTG-context] Disappearing characters
Hello all.
I have a file test-fonts.tex which just combines Palatino and Helvetica
into one typescript:
\loadmapfile[context-base]
\usetypescriptfile[type-buy]
\starttypescript [TESTfonts]
\definetypeface [TESTCombo] [rm] [serif] [palatino] [default]
[encoding=texnansi]
\definetypeface [TESTCombo] [ss] [sans] [helvetica] [default]
[encoding=texnansi]
\stoptypescript
And I have a simple test file which tries that typescript out:
\usetypescriptfile[test-fonts.tex]
\usetypescript[TESTfonts][texnansi]
\setupbodyfont[TESTCombo,14pt]
\starttext
Palatino? Normal \Delta, Maths \mathematics\Delta, Greek \greekDelta\par
Palatino? Normal \delta, Maths \mathematics\delta, Greek \greekdelta\par
{\ss Helvetica? Normal \Delta, Maths \mathematics\Delta, Greek
\greekDelta\par
Helvetica? Normal \delta, Maths \mathematics\delta, Greek \greekdelta\par}
\stoptext
With the line
'\setupbodyfont[TESTCombo,14pt]'
everything works well, but when I change it to
'\setupbodyfont[TESTCombo,10pt]'
the Delta signs disappear! (The lowercase deltas remain - weird?)
I am really confused (and it took ages to understand what was happening,
since the disappearing Greek originally occurred in a 700 page book...).
When comparing the log files for each version, the broken one (10pt) has
the line:
Warning: pdfetex.exe (file
c:\tex\texmf/fonts/type1/urw/palatino/uplr8a.pfb): glyph `uni20AC' undefined
whereas the working one (14pt) doesn't, and instead has:
{c:\tex\texmf-local/fonts/enc/dvips/lm/cmrm.enc}c:\tex\texmf/fonts/type1/public/lm/lmr10.pfb
So, it seems to be something to do with a missing switch to the font
which contains the \Delta character, but why should it only happen at
smaller font sizes? Experimentation suggests that 12pt and below has
this problem, and over 12pt the problem disappears.
Thanks to anyone who can explain and help me to fix it.

Re: [NTG-context] footnotes with one *
Thank you for your replies. They helped. I need two more twiks...
Twik 1:
My font is too slanted and the asterisk (*) is printed too close to the
last word in the sentence.
Example:
Charles IV \footnote[]{asdfasdf}
will print an asterisk touching the V letter.
How do I instruct context to give me some room before printing the asterisk?
Second twik:
How to control the distance between the page text and the line that separates
the footnote and the page text?
I tried the distance=, the height= arguments in the
setupfootnotes, but they don't do
what I want.

I think like this:
\defineconversion[starred][*]

Untested, but should work
It doesn't quite work.
If you give a single argument to \defineconversion, it expects the
conversion to be a command that takes an argument. Since you haven't taken
an argument, the number gets typeset after the asterisk. Also, the
asterisk needs to be in math mode to get positioned correctly, I
think. Correcting for both of those gives this, which works:
\def\gobble#1{}
\defineconversion[starred][\mathematics{*}\gobble]
\setupfootnotes[conversion=starred]
However, that's somewhat of a hack; better is to set up the footnotes to
reset the counter on each page, and then use one of ConTeXt's predefined
conversion sets that starts with an asterisk but follows it with other
symbols. That way, if one changes the file so that there end up being two
footnotes on the same page, they won't both get asterisks (which would be
confusing).
That can be done quite simply, like so:
\setupfootnotes[way=bypage,conversion=set 2]
Set 2 uses a \dag and then \ddag as the symbols after *, which is fairly
standard typographic practice. If you prefer to do a sequence of *, **,
***, and instead, try something like this:
\defineconversion
[asterisks]
[\mathematics{*},
\mathematics{**},
\mathematics{***},
\mathematics{},
\mathematics{\dag},
\mathematics{\ddag}]
\setupfootnotes[way=bypage,conversion=asterisks]

I don't think you can, actually. There are no metric files

Pdftex either uses entries from the 'lining' map file, or from
the 'oldstyle' mapfile, but it has no way of distinguising
between the two (the fonts have the same metrics).
The reverse of the old oldstyle trick should work though:

So once a map/encoding is defined for a given font/tfm set it cannot be
changed by declaring another map; interesting.

[NTG-context] Some gardening
Hello, Here's some more work for you Patrick, in case you get bored. (I guess I'll soon be removed from the list as a spammer/abuser if I continue writing mails such as this one :) What do the others think about it? # Source browser Can you escape control characters when searching through the source in ConTeXtgarden? For example, \def\somecommand now has to be written as\\def\\somecommand. And the search field is slightly small (only 20 characters). Well, I admit, these limitations can all be overcome by asking Mr. Google for \def\someveryveryverylongcommand site:contextgarden.net or by grep-ing on my hard disk. Also, after the search the right window is empty and sometimes 20 hits are found on the left. What about adding some context around the search term? For example one line before and one line after each hit (like Google does)? Once you have that, the same could be done for single files (if a specific word appears in one file more than once than you can select a file and see only the hits found + some lines before and after). If you also add a name=linenumber to the web pages with sources, than you can click on a hit and go directly to the line number where the search term occurs. # texshow-web I've just noticed that there's no possibility to describe single options for the commands. Take \setuplayout for example. Describing such huge collection of parameters in plain text is not clear, synoptic any more. It would be great if there would be a possibility to add descriptions for: - the command as such (already there) - every pair of braces (only one for \setuplayout), has to be visible if it is optional or not - every parameter inside a single brace - every single option for that parameter (for example: width=middle means that ...), default has to be marked Some classification/hierarchy/labeling of the commands could also be added, but this has to be thought of well before starting to implement it. For example page layout, floats, mathematics, colors, metapost, language, core functions, ... The top-level classification could probably be taken from prefixes of the source files. Enabling the Wiki functionality (bold, italic, tables ... texcode and context) and linking it to the source browser (to the place where \def\thisspecificcommand is) would also add another dimensionality. It would probably not be 100% compatible with the pretty-much-textbased texshow program, but ... I could imagine that one day something similar as modules.pdf (texshow.pdf) could be made from that page with pretty good documentation of (all ?) ConTeXt commands. The ability to add commands is already there I think (I have never tried it out yet). What about adding commands for (official and third-party) modules? It should be separated from the main page, but still offering the same functionality. I was also thinking about making some interface for translations of commands (for example: when a new third-party module is there, someone could translate it without much effort, some more exotic languages could be translated step-by-step, and new commands in ConTeXt could be found quickly and translated - the dutch interface is probably up-to-date, but I doubt that other translators are constantly checking if anything new appeared). But these things are much more conservative (commands may not change once they are translated) and probably not worth the effort yet. Finally a five-minute-work request after all that philosophizing: can you add link to the .po files under special in texshow-web and a submit new .po version button next to it?

[NTG-context] formatting verse
I've looked on the wiki and in the manuals for an equivalent to
LaTeX's \begin{verse} environment. I found a macro in a file on the
wiki, but the definition of it seems to be obsolete.
What I'm working on is converting a wedding service set using LaTeX
and the booklet package over to ConTeX and its built-in Imposition

Re: [NTG-context] Is there a mathematica typesetting manual for ConTeXt ?
Tobias Burnus said this at Sat, 14 May 2005 07:05:44 +0200:
(I have to admit, I cannot find m-math.tex/t-math.tex anywhere.)
I assumed Hans meant MathML. :)
\usemodule[mathml]
The basic math capabilities within ConTeXt do seem poorly documented,
mostly because they point to different sources, often in books. However,
ConTeXt does use Plain TeX as its model for mathematics.
The basics in ConTeXt are roughly equivalent to those described in:
http://meta.wikimedia.org/wiki/Help:Formula
(I don't know if it will specifically help you, but I note there's a
zh version of that page)
...but it takes some practice to spot the things that don't work directly
in ConTeXt. Some differences are unimplemented features, some are
differing conventions, some are because LaTeX thought they would be
useful, and ConTeXt hasn't (yet).
Some differences from the examples on that page that I notice immediately:
Math is best delimited inline with \formula{ ... }, not $ ... $
Display math is best delimited with \startformula ... \stopformula , not
$$ ... $$
\operatorname = \mfunction
The double-, triple-, and quadruple-integrals (\nt) are undefined in
basic ConTeXt's math.
The \begin{case} environment needs to be simplified into the Plain
\cases{} command.
The AMSmath/LaTeX-like:
$$ \begin{bmatrix} p q \\
r s \end{bmatrix} $$
...can be interpreted as...
\startformula
\left[ \matrix{ p q \cr
r s } \right]
\stopformula
This might not be the best answer to the original poster, but I do hope
it provides a bit of a guide to the general ConTeXt newcomer.

Hello, Xiao.
I'm glad I could help: I'm learning these advanced requirements as I go
along. My personal mathematics needs are much more modest.
I wouldn't give up on ConTeXt just yet. Try:
\loadmapfile[original-ams-base]
\starttext
\showmathcharacters
Note the \formula{\rightleftharpoons} and
\formula{\upharpoonleft\!\downharpoonright}.

Do you know how you would code that cycle in (AMS)LaTeX?

The double-, triple-, and quadruple-integrals (\nt) are undefined in
basic ConTeXt's math.
I must say thank you very very much!
In fact I've been looking for \iint in ConTeXt in the last two days -_-
so i'll try to use \int\!\!\!\int instead of looking for a ConTeXt
implementation :)
I met another problem today. Since there are not as many arrows in
ConTeXt as there
in AMS-LaTeX,I don't konw how to type the formula in the attached picture
which will
be referred in my presentation next Monday.
Hello, Xiao.
I'm glad I could help: I'm learning these advanced requirements as I go
along. My personal mathematics needs are much more modest.
I wouldn't give up on ConTeXt just yet. Try:
\loadmapfile[original-ams-base]
\starttext
\showmathcharacters
Note the \formula{\rightleftharpoons} and
\formula{\upharpoonleft\!\downharpoonright}.
\stoptext
Do you know how you would code that cycle in (AMS)LaTeX?
Hi,
I can code the cycle in ConTeXt,but it's too ugly and I will try to improve it.
here is my code:
\starttext
\placeformula
\startformula
\matrix{A+B{\Delta G_1\atop\rightleftharpoons}AB\cr
\Delta G_3\!\!\upharpoonleft\!\downharpoonright
\upharpoonleft\!\downharpoonright\!\!\Delta G_4\cr
A'+B{\rightleftharpoons\atop\Delta G_2}A'B\cr}
\stopformula
\stoptext
There is a similar example in The TeXbook(example 18.46).
You can try the follow code:
$$\def\normalbaselines{\baselineskip20pt
\lineskip3pt \lineskiplimit3pt }
\def\mapright#1{\smash{
\mathop{\longrightarrow}\limits^{#1}}}
\def\mapdown#1{\Big\downarrow
\rlap{$\vcenter{\hbox{$\scriptstyle#1$}}$}}
\matrix{0\cr
\mapdown{}\cr
0\mapright{}{\cal O}_C\mapright\iota
\cal E\mapright\rho\cal L\mapright{}0\cr
\Big\Vert\mapdown\phi\mapdown\psi\cr
0\mapright{}{\cal O}_C\mapright{}
\pi_*{\cal O}_D\mapright\delta
R^1f_*{\cal O}_V(-D)\mapright{}0\cr
\mapdown{\theta_i\otimes\gamma^{-1}}\cr
\hidewidth R^1f_*\bigl({\cal O}
_V(-iM)\bigr)\otimes\gamma^{-1}\hidewidth\cr
\mapdown{}\cr
0\cr}$$
Since i'm just a newbie of TeX, I don't really understand the first a few lines
of the solution. I still need some learning and practice :)

Re: [NTG-context] Is there a mathematica typesetting manual for ConTeXt ?
Le 13 mai 05 à 05:18, redox a écrit : I mean I want to type some math formulas with ConTeXt. Since i don't know too much about ConTeXt/TeX, i want to find a manual about this subject and to learn by myself. In the ConTeXt an excursion(page 15), it says, We advise you to do some further reading on typesetting formula in TeX. See for example: The TeXBook by D.E. Kunth The Beginners Book of TeX by S. Levy and R.Seroul I know that LaTeX(and AMS-LaTeX) has made some extensions to TeX in math typesetting, so I'm wondering if ConTeXt has also made extensions to TeX, or I can only type math formula in the way of basic TeX ? The first (only) starting point about math and context is http://contextgarden.net/Math The main AMS environnements are available with amsl module (should be in the recent context distribution, but not with the TeXlive-2004) http://contextgarden.net/Math_with_amsl Giuseppe Bilotta has also port the NATH LaTeX package (NAtural maTHematics) : http://contextgarden.net/Math_with_nath There is not yet documentation and sample about using thes module, but the documentation of there LaTeX LaTeX version is very usefull, Cordialement, Maurice Diamantini, ___ ntg-context mailing list ntg-context@ntg.nl http://www.ntg.nl/mailman/listinfo/ntg-context
Re: [NTG-context] Old-style figures throughout the document
Idris asked me about this during the previous thread, before I'd joined this list. Here's a slightly edited version of my reply about osf in documents with math: Well, I did the second-pass macros, and most of the math markup / editing of a recent translation of Thomas Harriot's _Artis Analyticae Praxis_ from 1631 or so, and it (of course) uses old style figures exclusively, pre-dating them, as would any mathematics (or other) text before the latter part of the 19th century. Old-style figures are named thusly since the now standard alternative lining figures are a fairly recent invention --- a Victorian (some would say debased) convention born out of expedience and a desire for better looking tabular material --- many railed against them, Charles Babbage being a notable example of the opposition to them (noting that in tables of logarithms, when used in difficult circumstances (I believe the example was an artillery officer doing ballistic calculations) absolute unambiguous representation could be a matter of life and death and that the extra differentiation provided by ascenders and descenders in numbers was highly desirable --- can't recall if Dr. Asaf Degani revisited this with his NASA reports on typography or no --- if not, he should've). Bringhurst's prescription (in his _Elements of Typographic Style) is perhaps a bit simplistic and doesn't acknowledge the typographical palette which has since become readily available in newer fonts (Hoefler Text in Mac OS X for example affords one proportional lining figures, monospaced lining figures, proportional old-style figures and lining old-style figures --- a text typeface I've been working on goes this even better, adding three-quarter height proportional and monospaced figures, and French versions of the old-style figure versions as well). Bringhurst's rule 3.2.3 would seem a better arbiter, ``Refer typographical disputes to the higher courts of speech and thinking.''. Knuth, in ``Typesetting Concrete Mathematics'' (_Digital Typography_, pg. 369) has a cogent observation when he writes, ``This experience proved to be worthwhile because it taught me that there is a useful and meaningful distinction between text numerals and mathematical numbers.'' There's been some discussion of old-style figures for mathematics on comp.text.tex, but I don't think any absolute statement could reasonably be made. It's certainly valid that using lining figures for mathematics does provide a useful distinction (and it also greatly eases typographic issues such as the placement of super and sub-scripts), but the counter-argument that mathematics is a valid textual discussion form is certainly appropriate as well. Arguably this would be a good place to use Bruce Roger's ``allusive typography'' principle. Anything set in a design more recent than Baskerville should use of lining figures in the absence of a reason not, while older texts could consider the use of old-style figures if concerns such as super and sub script placement can be worked out. But perhaps even that's too simplistic and formulaic. A far more productive thing probably would be to look at actual sample pages to consider things in context (sorry, couldn't resist the pun). Anyway, I hope this helps somewhat and is of use in your consideration.

RE: [NTG-context] oldstyle figures
= Original Message From Eckhart Guthöhrlein [EMAIL PROTECTED] should do everything you need: since u're not mixing text in \digits do you really need a global math font reencoding? In principle yes. For example, $f(x)=3x+7$ should come out with oldstyle figures, if these are used by default, shouldn't it? No, I don't think so (see below) Btw, striving for good typography, in which cases should oldstyle figures *not* be used? I am no typography expert, but I think that old style figures are, generally speaking, inappropriate for math mode. The various heights, etc. make more work for the brain in complicated mathematics expressions. I can't recall ever seeing good mathematics/physics done in old style figures. OS numerals are actually _text_ figures, as Bringhurst points out. In my own academic journal there is little to no math, but when someone mentions, e.g., the version of a computer program, I put the version number in upright figures, thought the rest of the journal is in os figures. That's my two cents, for what it's worth:-) Best Idris Professor Idris Samawi Hamid Department of Philosophy Colorado State University Fort Collins, CO 80523 ___ ntg-context mailing list ntg-context@ntg.nl http://www.ntg.nl/mailman/listinfo/ntg-context

The question is how to elegantly switch from standard (st2) tfm to

preserving \rm, \bf, \it, \bi.
basically, you declare a variant set for a (Serif/Sans/Mono) family:
\definefontvariant [Serif] [exp] [-Expert]
% [fam] [call abbrev] [synonym suffix]
Hallo,
thanks to Adam, it was easy to implement font variants. A little bit
more work was with all Storm glyph deffinition in two (+one) encodings.
Before I will do the support for the rest of my Storm font families I
want to ask audience (and especially Hans, Adam) to have a look into the
files (http://typokvitek.com/tmp/context-storm.zip). Example in
http://typokvitek.com/tmp/test-sdynamo.pdf (generaly interesting for all
\show... font related command usage). Recommendation for the package
improvements are welcomed.
There are:
enco-st1.tex - ec encoding with storm glyph extension
enco-st2.tex - xl2 encoding with storm glyph extension
enco-st3.tex - variants (additional glyph) for enco-st1 and enco-st2
type-sdynamo.tex - typescripts for Storm Dynamo font family
math-sto.tex - simple mathematics present in Storm fonts (in progress)
test-sdynamo.tex - test file
test-storm.tex - support for tests
Questions:
? During encoding deffinition I found some chracter name mess. I solved
it by synonyms:
E.g. \definecharacter textdag{\dagger}
\definecharacter paragraphmark {\paragraph}
\definecharacter textellipsis {\ellipsis}
\definecharacter textminus {\minus}
\definecharacter ostroke{\oslash}
\definecharacter textdollar {\dollar}
Is there some context convention for character names?
? I have a problem to define mathematics chars. I did:
\starttypescript [math] [dynamoRE] [st1]
\definefontsynonym [DynamoRE-Math-Letters][sdgr8te]
[encoding=st1]
\definefontsynonym [DynamoRE-Math-Letters-Italic] [sdgri8te]
[encoding=st1]
\definefontsynonym [DynamoRE-Math-Symbols][sdgr8te]
% \definefontsynonym [DynamoRE-Math-Extension][]
\stoptypescript
\starttypescript [math] [dynamoRE] [name]
\definefontsynonym [MathRoman] [DynamoRE-Math-Letters]
\definefontsynonym [MathItalic][DynamoRE-Math-Letters-Italic]
\definefontsynonym [MathSymbol][DynamoRE-Math-Symbols]
\definefontsynonym [MathExtension] [ComputerModernMath-Extension]
\stoptypescript
\starttypescript [DynamoRE] [st1,st2]
\definetypeface [DynamoRE] [ss] [sans] [dynamoRE] [default]

\startmathcollection[storm]
\definemathcharacter [+] [bin] [sy] [2B]
\definemathcharacter [=] [rel] [sy] [3B]

i prefer a safe copy

This is probably not satisfying, because you probably want to get new
mathematics commands working, but if this is to be used solely in text,
you could use (or expand to):
b\low{off}
\low (and \hi and \lohi) look like they work robustly in both math and

I'm a bit confused by you using \newcommand in your (ConTeXt?) examples,

Help?
This is probably not satisfying, because you probably want to get new
mathematics commands working, but if this is to be used solely in text,
you could use (or expand to):
b\low{off}
\low (and \hi and \lohi) look like they work robustly in both math and
text modes.
I'll see. I wonder if it will look the same. Especially in terms of
font. Do I get the same font in both sides? Do I get the same kerning?
I'm a bit confused by you using \newcommand in your (ConTeXt?)

though...
Yes, strange, isn't it? It just works. I copied one accidentally over
and it worked. So I kept using it.

Or more generally: how can I hardcode some PS/PDF code in .mp, not (yet) supported by metapost(play)?

The sphere graphic at the beginning of that file was done using MetaPost, so the circles could be drawn in color, but I know this isn't what you mean. Well - the main question is how to add the proper (smooth shading) color once I calculate the grid points in one way or another. The glyphs from the globe font (which I plan to improve) could be colored, e.g., by using the macros defined in the `colordvi.tex' file supplied with `dvips'. Of course, a given glyph could only be printed or displayed in a single color. GNU 3DLDF does not yet possess a `sphere' type, but I plan to add one in the not-too-distant future. I also plan to add shading, but that is in the more distant future. The shading methods I'm (vaguely) familiar with operate on raster data and I haven't quite decided how to handle rasterization. I'm leaning toward using the PNG format rather than PostScript for this. I believe PostScript can be used for both vector and raster data, but my memory of the details is hazy. Well, PostScript can be used for raster images, but that doesn't bring anything. The examples on Cass' page are actually done using *vector* graphics (colors are really calculated only in grid points, but then the color is interpolated by postscript interpreter): the perfect sphere coloring is thus really limited to floating point accuracy and printer capabilities. The spheres drawn directly in PostScript as in the examples above still have straight lines (well, I agree that with some mathematics it would be possible to draw them with proper splines as well). If you mean my spheres, that's an artefact of the PNG graphics. The PostScript versions look nicer. I believe that on commonly available devices, curves are ultimately drawn as short straight-line segments, though. In the code in that file, the circles have 64 points, and I thought the results were good enough. Raising it to some value x such that x % 4 == 0 and x 64 might improve them, I haven't tried it. 32 wasn't enough. No, I wasn't talking about the PNGs. I was talking about the PostScript pictures. http://www.math.ubc.ca/~cass/graphics/manual/code/doughnut.eps has a really *perfect* shading, but its edges are drawn using straight segments instead of drawing them with splines which damages slightly the whole impression of its perfectness. Some additional calculation for spline drawing would help, but I still find it easier to calculate the curves in metapost than in PostScript. Those straight-line segments on printers are just as straight as they are on any laser print-out of texts if I'm not wrong - i.e. not worth considering.

[NTG-context] shading in meta[post/play] PDF
There's a wonderful tutorial on drawing 3D graphics in PostScript on http://www.math.ubc.ca/~cass/graphics/manual/, specifically http://www.math.ubc.ca/~cass/graphics/manual/code/doughnut.eps as an example. And there's a detailed description on shading in PostScript in http://partners.adobe.com/public/developer/en/ps/PLRM.pdf, page 259 (I attached an example and have some more on computer if anyone is interested; I downloaded them from Adobe, but don't know the URL any more) or on shading in PDF in http://partners.adobe.com/public/developer/en/pdf/PDFReference16.pdf, page 272. (They're basically the same.) In metapost, perfect spheres can be drawn, like on http://www.gnu.org/software/3dldf/cdsmpls.html. But how can I add colour? Even if it would be too tricky to add colour and proper shading on the sphere - Is there any possibility to use advanced shading techiques described in PLRM inside metapost/metaplay for the most simple cases, say, like in the attached example? Metaplay allows circular and gradient shading and no others. I don't mind if I had to hard-code the shading. PSTricks allows some more advanced shading techniques and even direct PostScript code integration (with \special I think). Is anything similar possible in metapost/play? The spheres drawn directly in PostScript as in the examples above still have straight lines (well, I agree that with some mathematics it would be possible to draw them with proper splines as well).

Re: [NTG-context] At a loss how to proceed
Hans et al, OK, some questions. You say starting with pure tex, does this mean that if you start with Context, then tex4ht is not an option? Secondly, since I teach mathematics, anything I write is going to contain a *lot* of mathematics and a lot of figures (graphs, etc). Is XML and MATHML going to be painful in this case? How can I get started with a small project or example, so I can determine how to proceed? I think I can look at the latex followed by tex4ht direction myself, but I could use some help with the second method, xml to pdf via context and xml to html via xst. I really have no idea how to proceed with this direction. I could use some pointers, or even a small example, with math code and a metapost graph or two. Matthias Weber wrote: I am afraid your question is to vague to be answerable.

If you need formulas, use jpegs/pngs that have as a textual description a text that will be read as you would read the formula (eg: sum of 1 over n square for n from 1 to infinity equals pi squared over 6) it all depends on where one starts: tex or xml; starting with pure tex, tex4ht may be a solution; on the other hand, when one starts with xml, one can use context to produce the pdf's and xst to make html documents. Once you get accurstomed to it, editing in xml is not that bad and for math, there are math(ml) editors to make the complex formulas.

[NTG-context] nath and \mathematics
The following has to be added to nath for spacing to work correctly:

adding it anywhere after
\def$#1${\@@dollar{#1}}
seems to work fine. The problem is that $ is redefined, but
\mathematics doesn't catch on so the spacing gets all messed up.

[NTG-context] column balancing question
Good morning.
One reason for me to switch to ConTeXt were its macros for typesetting
in columns that are highly superior to any such macro I have ever seen.
(I typeset almost all my documnts in two columns.) But I am not able to
supress one strange feature: some pages are one more line longer than
they should be. It happen randomly -- or at least I was not able to find
out when it happens. Therefore I'm not able to prepare an minimal file.
I thougth that setting
\widowpenalty=0
\clubpenalty=0
\brokenpenalty=0
\normalbottom
may help, but it does not.
Can you tell me how to fix this very problem? Well, it does so on all
versions of ConTeXt I have ever tried and both with teTeX and TeXLive
distribution.
Many thanks for your attention and help.

Good evening,
Though Hans has sent already a piece of code ...
I saw that you are using height=fit, and width=fit. Did you ever try to
compile your file without these options? -- Some time ago I experienced
troubles with such options, although my layout was different and the
document was not setup with columns.

Re: [NTG-context] Bug report, \frac as redefined in m-newmat.tex
Hi Brooks,
Then, a couple of lines after that, there's the second definition for
\frac, which is the one that needed patching. This one, unlike the
first definition, is wrapped in \mathematics so that it can work outside
math mode.
So I'm wondering why only \frac has this second definition that allows
it to work outside of math mode. I would think that things should be
consistent -- either that all of the definitions in the first list
should be changed to use \mathematics, or that \frac should be returned
to the simpler version -- so that \tfrac is still simply \frac typeset
in text mode as one would expect it to be.
this has a historical reason; it was added because latex users expect
\frac to be there and to work in text mode as well;
Even if they're all left in the current form, I'd think that the unused
definition of \frac in the first list should be removed.
well, just consider it not to be there; it should definitely not be
mentioned in manuals -)
My argument for simplifying \frac to take the \mathematics out of it is
that it is a math-mode construct that typesets its arguments in math
mode, and allowing it to be used outside of math mode encourages sloppy
TeXing. It also hides the point of transition to math mode, meaning
that x and \frac{1}{x} will typeset x differently, which strikes me as
confusing. I recognize that this is a very debatable position, though,
and that there are at the very least arguments for backwards
compatiblity that contradict it.
if i remember right (maybe tobias burnus remembers more) it was mainly meant to be used in section titles; in such cases, when one sets a font explicitly, math is often not set up accordingly and frac permits one to do at least fractions

They don't need patching in the sense of fixing a bug, no -- it's more a
matter of consistency in behavior.
What I see is that there's a list of definitions for \frac, \dfrac,
\tfrac, and various other similar forms, all of which can be used in
math mode only, and do not use \mathematics.
Then, a couple of lines after that, there's the second definition for

Yes. For displaymath you can use plain TeX's $$\sum$$ or better

I don't make the \Sigma to be under and over characterised by i=1 and n.
In inline math you need \limits\sum if you want to have the i=1 below

Any suggestions on how to go about this? I mean, the obvious solution

Yes, this is generally true. All modules should get loaded

However, the units module still isn't working when nath is
loaded. Is it supposed to?
Well, I had never tested them together, and given the very
extensive changes nath enacts, I'm not surprised it doesn't
work.
Anyway, it looks like the fix is easy: the problem is that
dimension commands are not protected (unexpandable).
In m-units.tex, look for the lines
\def\dimensionprefix#1%

and change each

This should solve the problem.
I'm not 100% sure this is the best solution, though. An
alternative could be to keep those definition as they are and
instead make unexpandable the actual commands (\Micro etc).
Hans, what do you think?

The problem is caused by \frac being defined in the newmat

If you comment that line, it will compile flawlessly.
Hans, why would you want to allow \frac in text mode?
Changing it to \dfrac makes the input compile ok, but
typesets the cases in an ugly manner with really narrow

(Yes.)

Yup, I just changed a couple of things and now we have a

Here is my 10 minute solution ... if i'm in the mood i can make an
option of it
Maybe other people would like some support for this kind of thing.
Certainly I would find it useful if, when I wrote `\inmargin'
somewhere inside a paragraph, I could specify an option to determine
the vertical alignment of the marginal material. Suppose `top' aligned
the top of the marginal material with the top of the paragraph, `mid'
the middle of the marginal material with the midpoint of the paragraph,
and `bot' the bottom of the marginal material with the bottom of the
paragraph. That would be good.

\scratchdimen\MPy{figpar:b:\CurrentFigPar}%
\advance\scratchdimen-\MPy{figpar:e:\CurrentFigPar}%
\advance\scratchdimen-\ht\scratchbox
\advance\scratchdimen\lineheight
\else
\scratchdimen\zeropoint
\fi
\vbox{\vskip.5\scratchdimen\box\scratchbox}}%
\indent\hpos{figpar:b:\CurrentFigPar}{\strut}\ignorespaces}
\def\StopFigPar
{\removeunwantedspaces\hpos{figpar:e:\CurrentFigPar}{\strut}\endgraf}
\starttext
\input tufte
\StartFigPar{\externalfigure[cow.pdf][width=1cm]} \input tufte
\StopFigPar
\input tufte
\stoptext=20
Thank you very much indeed, Hans. This puts cow.pdf in the right place
in the margin. One problem remains. Surrounding a paragraph by
\StartFigPar\StopFigPar often messes up the inter-paragraph vertical
spacing. In particular, surrounding \startformula\stopformula by
\StartFigPar\StopFigPar introduces big spaces above and below the
mathematics.
Is there a simple way to stop this? It would be good if introducing a
few \StartFigPar\StopFigPar pairs to a document had no effect at all
on the main body of the document, and just put figures in the margin.

[NTG-context] alignment of marginal material
I am trying to write a macro which places a picture in the margin. I
would like the centre of the picture to be aligned vertically with the
centre of the paragraph in which I call the macro. The following works
in simple cases:
\def\hazard#1{%The argument is the text of the paragraph
\setbox0=\vbox{#1}% I do this to work out the height of the paragraph
\inleft [low] {%
\framed%
[height=\ht0,% This makes the height of the frame equal to the
height of the paragraph
top=\vss,%
bottom=\vss,% These two lines centre the picture in the frame
frame=off]%
{\externalfigure [sharp turn sign]}%
}%
#1}% It goes wrong if you replace #1 with \box0
If I type something like
\hazard{paragraph text}
this produces what I want. But it breaks down with mathematics.
\hazard{%
\startformula
mathematics
\stopformula
}
produces the picture aligned with the bottom of the mathematics.

[NTG-context] Re: Can I compare with someone?
Staszek, I've recently installed tetex 2.0.2. I am having difficulty with Metapost [...] Now, when I compile, texexec seems to be invoked. Is this what happens on your systems? Is this correct behavior? [EMAIL PROTECTED] darnold]$ mpost junk This is MetaPost, Version 0.641 (Web2C 7.4.5) (junk.mp TeXExec 4.0 - ConTeXt / PRAGMA ADE 1997-2003 It seems that somebody changed texmf.cnf, e.g. declaring here something like: TEX = context Aha! I found this in my texmf.cnf. % What MetaPost runs to make MPX files. This is passed an option -troff % if MP is in troff mode. Set to `0' to disable this feature. MPXCOMMAND = texexec --mptex or, worse, changed makempx script. Anyway, tetex 2.0.2, as it is distributed is OK. I've observed that some Linux distributions provide changed tetex config files, not always in a happy way... I don't know how such situation could be cured, as packages are often not signed. The notable example is still not updated tetex in the _current_ RedHat9.0. It is still tetex 1.0.7, but broken in many parts. -- David Arnold College of the Redwoods.

[NTG-context] columns and alignment at the bottom
Hi,
I am trying to typeset a text which should look roughly like that:
|-| |-| |--|
|text | |text | |text |
| | |-| | |
|-| | |
|-| | |
|-| |text | | |
|text | |-| |--|
| |
| | |-| |--|
| | |text | |text |
|-| |-| |--|
So I have a frames with some text (actually, addresses - Hans, maybe
you remember the address booklet I showed you here in Darmstadt) in
three columns. So I tried something like:
\startcolumns[n=3]
\framed{first address...}
\vskip 0.5cm plus 1fill
\framed{second address...}
\vskip 0.5cm plus 1fill
\framed{third address...}
.
.
.
\stopcolumns
Which (obviously because I use TeX code inside ConTeXt - shame on me)
fails, the frames are not aligned at the bottom.
So I'm looking for a way to typeset them with a distance of at least
0.5cm and align at the bottom - the remaining space should be spread
equally...
I hope the question is understandable and I hope someone has already
done something like this...
Greetings,
ALeX
P.S.: Hans, thanks again for the tutorial in Darmstadt - now I know
about the layer and overlay stuff, I use it extensively :-)

[NTG-context] CJK support in ConTeXt
It's time to discuss the topic CJK support in ConTeXt in a more public place. The current version of ConTeXt supports Chinese only. But the same mechasism enables Korean too. The remaining language is Japanese. In some sense, it is possible to support Japanese in the current subfont mechanism. But several issues (e.g. Japanese kerning system as explained by Okumura) may occur. So, alternative way is to use ASCII pTeX for Japanese. Basically looks no problem but I worry eTeX extension features. Is it possible to run ConTeXt without eTeX extension features, Hans? My suggestion for supporting CJK characters in ConTeXt is to write a new module using e-Omega. Even though e-Omega does not produce PDF format directly, there are not much problem with DVIPDFMx.
