The characters are squeezed together because the font has wrong metrics.
If the assumption that mdugmr7m.tfm contains the metrics for
md-gmm7m.pfb is correct, then fontforge show it (mdugmr7m), contains
bold characters, which then should show.
When you use a Type 1 math font with ConTeXt MkIV all characters in the
different
files are mapped to the corresponding unicode points but these mappings
aren’t
complete (e.g. bold uppercase greek letters aren’t mapped).
For some fonts you would also need a custom mapping because not all fonts
put the symbols in the same position.

Re: [NTG-context] kpfonts, math, type 1 font
As for the first point: buggy afm files, I've tried generate font
from fontforge interface:
Even though I've let fontforge proceed to many auto-corrections, the
output produced
and then installed seems not to fit the bill: nothing is showing.
I reckon I've learned as much as can be done in one go:
= I temporarily give up.
Nevertheless if one have information about the vector I wrote for bold Greek:
why that didn't work, I'll will gladly have it.

indeed you have to make such a table for any math font combination you
want (when using type 1 fonts)
In this example, I believe the files involved are tfm files
(ugmr8a.tfm, mdugmr7m.vf, in
http://packages.debian.org/squeeze/all/texlive-fonts-extra/filelist)
Note: the afm files of kpfonts are ziped in the doc directory.
And I've got vf files, 688 of them.
normally you don't need more files than the ones you mention in the
table; best prevent too much polution of your tree by tfm/vf files
(if you know exactly what you need you can make a path fonts/data/xxx/
and put all relevant files there so that you keep the overview)

Thanks, I'll experiment in that direction and say when there are results.
The files like tfm, afm, pfb,... seem to be found alright by mtxrun
--script fonts --reload when they are in the ${HOME}/texmf/fonts/
tree, so I think I can leave them there.
So I should make a sort of copy of mdugm-math.lgf and call it
kpfonts-math.lgf, and put it in
${HOME}/context/tex/texmf-context/tex/context/fonts/.
[Do the same with a copy of type-imp-mathdesign.mkiv, which
contains: \loadfontgoodies[mdugm-math].] Or rather put a typescript
in my document file as explained here:
http://wiki.contextgarden.net/Math_fonts, and insert some
\loadfontgoodies[kpfonts-math] in it.
Execute: context --make en. And that should be it.
What is the \s! syntax for, as in \s!Serif?

The Palatino one I haven't found;
The Garamond-math one might be that: mdugm-math.lfg:

{ name = mdugmmi7m, vector = tex-bi, skewchar=0x7F },
{ name = mdugmr7y, vector = tex-sy,
skewchar=0x30, parameters = true },
{ name = mdugmr7v, vector = tex-ex, extension = true },

Hi everybody,
(best wishes for this new year by the way).
There is this font:
http://www.ctan.org/pkg/kpfonts
Which is a postscript type 1 font, text and math.
I've copied the files in the right places in the ${HOME}/texmf tree.
And a call to:
mtxrun --script fonts --list --all --pattern=*kp*, after a
mtxrun --script fonts --reload
seems to indicate that it is found by context all right.
But now I haven't got the faintest idea on how to use it in a ConTEXt
document -- text + math.
My ConTEXt is beta not older than a fortnight.
All examples I've found that could possibly apply were at least far
too complicate for my understanding, also likely outdated.
Using a text font in type1-format is very easy, all you need is the afm and
the pfb-file.
The font files are put in the tex folder and to use them in your document you
have to write a short typescript, below is a example how to use the urn
garamond font.
\starttypescript [serif] [charter]
\setups[font:fallback:serif]
\definefontsynonym [Serif] [file:ugmr8a.afm] [features=complete]
\stoptypescript
\definetypeface [mainface] [rm] [serif] [charter] [default]
\setupbodyfont[mainface]
\starttext
\input knuth
\stoptext
The same has to be done for the kpfont but there is one problem, the archive
on cyan doesn’t provide afm-files and you have to generate them yourself.
Since the font provides only tfm-files it would be also possible to them but
it’s better to work with afm-files.
Adding support for the math font requires more work because you have to write
also a Lua file where you specify which file is used for symbols, operator,
letters etc. This isn’t very complicated (you can just modify the files for
palatino or garamond math), you have to only look which files are used for
the math fonts.

Re: [NTG-context] luatex lunatic
Now that we have double-precision mathematics in MetaPost, you can
easily make calculations directly in MetaPost. You can also make such
calculations directly in lua without relying on libraries as the
functions are rather simple.

Rather than

you can just use:
\definemathframed[graymath]
[

This way, you can even override the options when using \graymath:
\graymath[backgroundcolor=red]{...}

Using context mode=mkiv compiles the coding using MkIV, but
contextgarden uses a rather old version of mkiv, so it is unlikely that a
feature introduced a few months ago will run on the garden.

You need to use another one:
$$\sum\frac{1}{\frac{1}{\frac{1}{\frac{1}{2$$
$$∑\frac{1}{\frac{1}{\frac{1}{\frac{1}{2$$

Hi,
\nabla should be italic if all other math greek symbols, like \Omega, \Gamma,

Re: [NTG-context] upto current
On 19 mars 2013, at 19:47, Aditya Mahajan adit...@umich.edu wrote: […]Although most active users use ConTeXt standalone and are willing to update frequently, TL still plays an important role in introducing new users to ConTeXt. An experienced TeX user who wants to try ConTeXt is more likely to try ConTeXt distributed as part of TL rather than ConTeXt standalone. When there are serious bugs with ConTeXt TL, it gives the impression that ConTeXt is not a mature macro package. Hi, To support what suggests Aditya, I would like to say that the main issue with the current state of ConTeXt in TeXLive (either mkii or mkiv) is that most « lambda » users of TeX whom I know in the mathematics world and in accademia, that is: --- users who are not familiar with what should be changed in TeXLive, --- users who don't even know TeX and LaTeX are not synonyms, --- users who don't know that there exist another environments and macro packages for typesetting tex-files, --- users who don't know that using ConTeXt one can do better typesetting, and that it has better features, all those users are not going to install a stand alone ConTeXt. They would use TeXLive, they would try everything in it, but all they want is to write a paper and typeset it with a TeX package with a single command (or in the case of Mac users, from within TeXShop or another editor). Most of them do not even know where TeXLive sits on their computer, and they don't know how to install something new. Unfortunately, the ConTeXt in TeXLive does not work out of the box: the user has to issue a few commands before he can typeset a file with ConTeXt, either mkii or mkiv (for instance on my installation of TeXLive, after having issued a few commands, which I don't remember right now, I can use ConTeXt with LuaTeX, that is mkiv, but I cannot use mkii). For my part I have been advocating ConTeXt among my colleagues (especially for course materials and books, since submitting a paper to a journal is essentially impossible if it is a ConTeXt file). Most of them agree that ConTeXt gives a much better result, but when it comes to how to use ConTeXt from TeXLive they are afraid and don't go further. For some of them I have installed a stand alone ConTeXt, but most of them do not update their installation, since they would not use the most recent features or improvements (for most of day to day typesettings, when one does not use complexe features, even a beta version is sufficiently stable for such users). So my pledge is this: make any stable version of ConTeXt in TeXLive so that it works and typesets a tex-file « out of the box », without needing to issue any command other than: context myfile.tex This is the case with LaTeX inside TeXLive, and so I cannot see any strong reason for ConTeXt not having the same behavior.

Re: [NTG-context] MetaPost Function Grapher
Hello Troy. Thank you very much for the link. It looks very nice and I'm sure that I will throw into teaching (I teach mathematics at the high school). I'm doing these things through Tikz and Pgfplots. Metapost unfortunately I don't control. Is it possible allowing export to Tikz or Pgfplots? If I would had the opportunity to also download the source Tikz or Pgfplots, it would be absolutely amazing. My point is that I can post the graphs still adapt, modify, describe, and create animations from those exported sources. Anyway, it's very hilarious application and I provide the link my students for their study purposes. Kind regards. Jaroslav Hajtmar Dne 22.2.2013 19:44, Troy Henderson napsal(a): The MetaPost output from my Function Grapher http://www.tlhiv.org/mpgraph/ is now available in ConTeXt format. This can be illustrated by choosing a graph type and selecting an example from one of the Example buttons. Once the graph is drawn, the ConTeXt source can be downloaded using the Download drop-down box. Simply executing `context mpgraph.tex` should produce the same graph viewed on the website in PDF. If you see any bugs, feel free to let me know.

Re: [NTG-context] \| should give two || and not one
Hi All, In a way, it is correct that for compatibility reasons and and convert it is good to keep the old syntax. Yet, ConTeXt is suppose to be more natural. Personally, I find some of the names used in TeX and LaTeX often hard to find. Whenever, I needed a function or symbol I to often go look it up. I mean that \vert and \Vert are still cryptic. They can stand for abs, for all in, etc. .. Me, I prefer names that reflect the their functions, regards Keith. Am 18.02.2013 um 10:51 schrieb Mikael P.

Re: [NTG-context] \startitemize[columns] once again...
Hi Marcin,
I think there is a small bug with itemize and columns: in another thread (with
Subject « vertical alignment problem in column items» ) Dalyoung reported also
an issue, which is related to what you have observed.
Please see my message in a reply to Dalyoung's message, where I reported some
testings but I am not sure when this bug appeared (in mkii, the behaviour is
essentially correct).

[NTG-context] xml cross-references in lua?
Hi all, I have a question about xml processing and I think that what I want/need can best be achieved by using lua code, but so far, I'm not really sure how to proceed, so any help from one of the resident lua gurus would be welcome. So: the question. xml allows to provide elements with unique identifiers so that one can add cross-references within the document structure.

If the number of bib items is not that large hashing does not save much.

I'm sorry, I'm telling you nonsense. There are no Greek letters in
LucidaBrightOT, but they are present in LucidaBrightMathOT. The italic
version starts at 1D6FC and the regural one is in the normal Greek
range.
This is
the case for LM, Lucida and probably a few more fonts. (Another option
would be to define the counter to run through greek letters in math
font.)
Or to leave the counter untouched and wrap it into a substitution
function -- is there a chance you (or anyone else) could supply
me with a mapping of the “real” Greek code point to the “math
Greek” one?
See math-map.lua. If you need any help or explanation, please ask. I
believe that the following part might be relevant (but only if you
need italic):
lcgreek = {
[0x03B1]=0x1D6FC, [0x03B2]=0x1D6FD, [0x03B3]=0x1D6FE,
[0x03B4]=0x1D6FF, [0x03B5]=0x1D700,

[0x03C3]=0x1D70E, [0x03C4]=0x1D70F,
[0x03C5]=0x1D710, [0x03C6]=0x1D711, [0x03C7]=0x1D712,
[0x03C8]=0x1D713, [0x03C9]=0x1D714,
[0x03D1]=0x1D717, [0x03D5]=0x1D719, [0x03D6]=0x1D71B,
[0x03F0]=0x1D718, [0x03F1]=0x1D71A,
[0x03F4]=0x1D6F3, [0x03F5]=0x1D716,
},
Yeah, appears to be the correct range. Couldn’t test with Lucida,
though.
For regular variant of Lucida it should be enough to use Math font
instead of the normal one, but I didn't test or write any code for it.
For LM you would have to use the italic version since upright (without
resorting to cm-unicode) looks horrible anyway.
But if there’s a math font, I’d go with the example that Wolfgang
posted; alternatively just wrap the converter into \mathematics:
\unprotect
\def\math_greek_characters#1{\mathematics{\greeknumerals{#1}}}
\defineconversion [mathgreek] [\math_greek_characters]
\protect
etc. It will depend on your choice of math font whether you get
italics or upright glyphs.

Re: [NTG-context] ConTeXt-- does it make sense for my needs?
Welcome to ConTeXt! I'm a relatively new user so my answers will be brief and partial, but I'm sure others will be able to expand on them. On Tue 13 Dec 2011, Chris Lott wrote: 1) My work is primarily in the humanities and end-user technologies, with small amounts of coding. So mathematics isn't an issue. I do a fair amount of highly academic writing (aka: many sections, citations [handling this in a sensible way is really important], footnotes) with the occasional need for charts, graphs, and photos. In other words, I'm not doing the kind of layout one might associate with InDesign or the like. I also write many paper letters (personal), poetry, fiction, essays, and the like. This looks to me like a good use case for ConTeXt. I've used it for a 380-page dissertation with the full complement of academic paraphernalia: footnotes, appendices, table of figures, citations etc. which all worked well for me. I believe that many others are using it for similar work. 2) That said, I (obviously) have a keen interest in typography, and that includes wanting to use some particular typefaces... I've paid good money for many of them, so why not? I've found ConTeXt to be more pleasant than LaTeX for setting up the layout and typography according to my wishes. (When I used LaTeX I generally just went with the default layout and accepted that things would be a little ugly.) ConTeXt is also good about letting you use your own typefaces -- particularly if they're in OpenType format. 3) PDF is my primary medium of exchange, though I would like to efficiently exchange docs with colleagues, which might mean getting them into something they can open with their beloved Microsoft Word... is there an RTF output for ConTeXt? this isn't super-high on my list, but it would be nice. 4) How about X/HTML? this is my lowest level need but, again, it would be nice. I know that ConTeXt supports direct XHTML output but I'm not sure how mature it is -- I think someone else will be able to provide a more complete answer to this. So, do you think ConTeXt makes more sense than LaTeX? And *what* is the deal with xetex? It seems to be the easiest way for accessing all my fonts, but it also hasn't been updated for years and, since it is tied to an old version of ConTeXt (as far as I can tell) it doesn't seem like much of a winner. In short, there are two versions of ConTeXt: Mk II (stable, and frozen for some time now) and Mk IV (actively developed, new betas more than once a month). Mk II can use pdftex or xetex as the engine; Mk IV uses luatex, which provides the ‘it just works’ font handling of xetex alongside a number of other features (chiefly the integration of the lua scripting language). Despite the worries that may be occasionaed by the word ‘beta’, Mk IV is pretty stable and definitely the recommended option these days. Hope this helps!

[NTG-context] ConTeXt-- does it make sense for my needs?
Many years ago I used LaTeX quite a bit for academic work, including a fair amount of Memoir class. Back then ConTeXt was quite new, so I didn't mess with it much. Now I'm back and sick of Word/etc for the documents I need to produce as print/pdf and for interaction with colleagues. What I can't figure out is if ConTeXt makes the most sense... and if it does, I have a few questions... 1) My work is primarily in the humanities and end-user technologies, with small amounts of coding. So mathematics isn't an issue. I do a fair amount of highly academic writing (aka: many sections, citations [handling this in a sensible way is really important], footnotes) with the occasional need for charts, graphs, and photos. In other words, I'm not doing the kind of layout one might associate with InDesign or the like. I also write many paper letters (personal), poetry, fiction, essays, and the like. 2) That said, I (obviously) have a keen interest in typography, and that includes wanting to use some particular typefaces... I've paid good money for many of them, so why not? 3) PDF is my primary medium of exchange, though I would like to efficiently exchange docs with colleagues, which might mean getting them into something they can open with their beloved Microsoft Word... is there an RTF output for ConTeXt? this isn't super-high on my list, but it would be nice. 4) How about X/HTML? this is my lowest level need but, again, it would be nice. 5) I generally use a Mac for everything, but I am pretty comfortable in the shell. I've done a bit of programming in PHP. I don't mind monkeying around, and I am interested in creating layouts that suit my needs, but digging into internals is not for me. I used Emacs extensively for years, now using mostly Vim (MacVim) and a variety of GUI editors depending on what I had for breakfast that day. So, do you think ConTeXt makes more sense than LaTeX? And *what* is the deal with xetex? It seems to be the easiest way for accessing all my fonts, but it also hasn't been updated for years and, since it is tied to an old version of ConTeXt (as far as I can tell) it doesn't seem like much of a winner. Finally, if ConTeXt is the way to go, are there any fairly comprehensive materials in one place for learning to use it? What I find on the wiki seems to go from basic to advanced without a lot of in between, and what I find on the web seems a bit fragmented. but at this point my head is in a whirl, so I might just be missing some obvious material.

Thank you! I will wikify the examples with an explanation on the

without explanation on their exact syntax and use cases.

Re: [NTG-context] [beta] grid head
Hi Hans,
the new beta appears to modify the behaviour of long headings on
the grid. In the following example the chapter head moves up into
the page header which it did not prior to the update (cf. mkii’s
behaviour):
·
\setuppapersize[A5][A5]
\setuplayout[grid=verystrict]
\setupheadertexts[{Blindtext}][{\tfb\bf \pagenumber}]
\setuphead[chapter][
style=\WORD,
grid=yes,
]
\starttext
\chapter
{This is supposed to mimick a rather long chapter title as is
common in German language environments; shorter titles might not
look as natural as longer ones}
\dorecurse{5}{\input dawkins\par}
\stoptext \endinput
·
Gridless it works ok. I’d just like to know whether this is to be
taken as a bug or as a feature. Thanks a lot,
Philipp

Hi Hans,
my xml files seem to run OK (I just did a few experiments). However,
there is a problem with the new project structure code. My book project
is set up like a proper ConTeXt project, and with the new version,
context has lost the ability to compile single components.
context mycomponent
will compile the entire document, and then append the single mycomponent
at the end of the document. That can't be right...

is there a module or a package people have created for common things

`\set{ a, b, c }` for a set.
`\EV{X}` for the expected value.
`\P{ X = ½ }` for the probability.

If not, maybe a module could be created and maintained together to not

See the mathsets module[1]. The current module does not work with MkIV (I
need to debug that; most likely due to catcode changes for _ and ^. I am
planning to reimplement the module using lpeg but that is on a low

It might be that I am missing something here. But I don not understand why in

\starttext
$\tfd Q,Y,N,P,Y,Z \quad PYR$

I don't know enough about the zillions of math parameters in fonts,
but you will notice exactly the same behaviour in plain TeX.
If you need to have a variable PYR, you should probably do
\def\PYR{PY\kern-2ptR}
$\PYR$
(modify kerning at your own will; you might also want to use em
instead of pt units, or you could use \! if you don't need to be too
accurate)
The extensive original spacing is most probably related to the fact
that in mathematics you usually mean multiplication when you write one
letter after the other. In other cases (for example when you have a
function like sin, cos, lim, ...) the spacing will look better.
Still, the fact that there is such a huge difference between PY and YR
looks more like a tiny font bug to me (but it is already present in
CM, so LM is unlikely to change it, at least until they switch to
OpenType Math).

[NTG-context] defined symbols - question/feature suggestion
Hi Hans, in symb-mis.mkiv you define most symbols with \mathematics. I don't know why you take these symbols from the math font. Just in case the symbol does not exist in the regular font, I would guess. Problem is only, that you will loose most symbols when switching the math font to something else than computer-modern (I tested with euler and cambria). BTW: I wonder how many contexters use modern for math... Anyway it appears most fonts have geometric shapes and common symbols and dingbats. So I end up redefining the symbols: \definesymbol [bullet][\textbullet] \definesymbol [dash] [--] \definesymbol [star] [\char2734] \definesymbol [triangle] [\char25B6] \definesymbol [square][\char25A0] \definesymbol [diamond] [\char25C6] \definesymbol [checkmark] [\char2713] Also it looks nicer when you use item symbols matching the text font. Maybe you would consider this and prefer symbols from the text font rather than those from the math font and keep \mathematics only as fall back should the glyph be unavailable.

Just to be sure I've updated the Minimals, but with
\enablemode[*nofonts]
in cont-new.mkiv it fails.
I don't need a workaround, because I can comment out the *nofonts in the
cont-new.mkiv (which was added by myself). I was just reporting a
problem, as asked (IIRC).

Re: [NTG-context] \qedhere equivalent in ConTeXt
Hi list,
I tried something similar to (Mk IV version 2011.11.18 19:34):

right, as in (consider the extra space, which avoids the hyphenation):

Any help appreciated. Thanks in advance,

[NTG-context] new beta
Hi,
I uploaded a new beta:
The character definitions have been updated (esp math, thanks to Aditya).
After some testing by Wolfgang the decision was made to permit _ in
macronames in modules. So, the following works:
\unprotect
\def\test_test_test#1#2{#1+#2=whatever}
\test_test_test{1}{2}
\protect
In principle we can also support ^. The mkiv code base no longer uses _
and ^ in math in modules and those who write modules should avoid them
as well. So, when writing macros in unprotected mode, one schould use:
$x\normalsuperscript2\normalsubscript n$
Taco and I think that we can safely switch to \nonknuthmode in mkiv so
this might happen soon (which means that _ and ^ become normal
characters in text mode). Actually, being permanently in \nonknuthmode
would permit _ and ^ in modules again.
We could even make _ and ^ always letters outside math in which case
\text_test etc would become possible everywhere but that needs some more
consideration. In that case
\def\make_subscript#1#2{\mathematics{#1_{#2}}}
\make_subscript{x}{2}
becomes valid everywhere. We can discuss this in detail at the dev list.

Re: [NTG-context] Proposal for math mappings
Dear Aditya,
I do think that your proposal would be of great help in writing mathematics.
Indeed the use of different alphabets, or range of characters with different
styles, depend on the fields of mathematics, so having a \setup command like
the one you suggest would be wonderful.
However, IMHO, the new setup command should follow the general rules of ConTeXt
commands for setting up different environments. So maybe the option of having
all the 12 forms, as you suggest,
normal, italic, sans, sansitalic, blackboard, script,
bold, bolditlaic, boldsans, boldsansitalic, boldblackboard, boldscript
would be more homogeneous with the usual style choice.
Best regards: OK

There are five different ranges in mathematics:

Should be: αβγ..ω

Thanks. I need to learn my Greek :)
A user may want to control what each range is mapped to. So, I suggest a
setup
command
\setupmathmappings
[
digits={style,alternative},
lclatin={style,alternative},
uclatin={style,alternative},
lcgreek={style,alternative},
ucgreek={style,alternative},
]
where the options for style are
normal, bold
while the options for alternative are
normal, italic, sans, sansitalic, blackboard, script
This command will the mappings for each range. **NOTE**: All combinations
are not valid.
A companion command
\definemathmappings
[whatever]
[]
can be used to define multiple mappings. These mappings can be used by
\setupmathmappings[whatever]
(An alternative is that these mappings are activated using \whatever ...)
For example, we can define a command to typeset vectors using
\definemathmappings
[vectors]
[ digits={bold,normal},
lclatin={bold,normal},
uclatin={bold,normal},
lcgreek={bold,normal},
ucgreek={bold,normal}]
\def\VEC{\groupedcommand{\setupmathmappings[vector]}{}}
Is it should be
\def\VEC{\groupedcommand{\setupmathmappings[vectors]}{}}
?
Indeed. Thanks.
If later, we want to represent vectors as sans serif, we can use
\definemathmappings
[vectors]
[ digits={normal,sans},
lclatin={normal,sans},
uclatin={normal,sans},
lcgreek={normal,sans},
ucgreek={normal,sans}]
This interface makes it easy to switch math fonts for disiplines that want
different style for different alphabet ranges.
It is relatively easy to implement the above interface. All we need
is some bookkeeping to set the right attributes. The default math
mapping commands can be reimplmeneted using \definemappings. Before
implementing this, I want to ask the opinion of other math users.
Would the above interface take care of different use cases, or is it missing
something?
IMHO, style is already used so it is normal.
Finally, I am not too happy with the syntax. There are only a few ConTeXt
commands in which the keys take a pair of values. Another option is to
allow all
12 valid options
normal, italic, sans, sansitalic, blackboard, script,
bold, bolditlaic, boldsans, boldsansitalic, boldblackboard, boldscript
This very depends on used fonts.
I am assuming a complete opentype math font.
with the variants sansitalic-italicsans, boldsans-sansbold, etc. as
synonmyms.
Which way of specifying the keys do you prefer?
Actually I don't get what you try to do.
I'll try to explain better in a later post.
I thought that 'font
switching' command should take care of font switching either in math or
text modes (if typescript is set properly).
I am proposing to separate out math font switching from text mode font
switching.
Right now the only good
example of usage of proposed mechanism is \VEC command (for vectors and etc).
More on this later.

Re: [NTG-context] Proposal for math mappings
I'll try once more to explain the setup.
If I understand the unicode philosopy correctly, then we do not any font
switching macros in math. If we want math italic A, we can simply type
0x1D434; if we want math bold A, we can type 0x1D400; and so on.
One difficulty with this approach is that it is not easy to type (and see)
these characters in an editor. One way to circumvent this, as is done by
the latex unicode-math package, is to define a macro for each symbol:
\mathitA, \mathbfA, etc.
Even if we define such macros, writing such macros is inconvinient. A more
nature way is to write $A {\bf A}$ rather than $\mathitA \mathbfA$ etc.
Traditionally, commands like \bf, \it, etc are font switches. However, in
unicode math, rather than font switches, these macros are simply input
mapping commands. Thus, by default, 0x0041 (latin A) maps to 0x1D434 (math
italic A), and so on. If \bf is active, 0x0041 (latin A) maps to 0x1D400
(math bold A), and so on.
Roughly speaking, this is how \bf. \it, \bi, \cal, \Bbd, etc work in the
background. However, at present these mappings are unsatisfactory. For
example, by default, 0x03B1 (Greek alpha) maps 0x1D6FC (Math italic small
alpha), while 0xO391 (Greek capital Alpha) maps to itself. What should
these mappings be when \bf is active? Or when \bi is active?
The trouble with the current implementation of \bf, \bi, \cal, etc is that
these mappings are not explicitly specified. My proposal is to allow users
to customize these mappings.
I agree that digits, upper and lower case latin and greek does not capture
all mathematic characters for which such mappings are needed. Similar
mappings might also be needed for some symbols like nabla (are there other
such symbols?). These can also be added as a key like
nabla={normal,italic}
or
nabla={bold,normal}
Hopefully, the above explanation makes more sense.

If later, we want to represent vectors as sans serif, we can use
\definemathmappings
[vectors]
[ digits={normal,sans},
lclatin={normal,sans},
uclatin={normal,sans},
lcgreek={normal,sans},
ucgreek={normal,sans}]
This kind of switching would be great.
This interface makes it easy to switch math fonts for disciplines that want
different style for different alphabet ranges.
It is relatively easy to implement the above interface. All we need is
some bookkeeping to set the right attributes. The default math mapping
commands can be reimplmeneted using \definemappings. Before implementing
this, I want to ask the opinion of other math users.
Would the above interface take care of different use cases, or is it
missing
something?
It looks good. Some examples would be needed, starting at simple ones and
ending with wildly switching math formulas.
Finally, I am not too happy with the syntax. There are only a few ConTeXt
commands in which the keys take a pair of values. Another option is to
allow all
12 valid options
normal, italic, sans, sansitalic, blackboard, script,
bold, bolditlaic, boldsans, boldsansitalic, boldblackboard, boldscript
with the variants sansitalic-italicsans, boldsans-sansbold, etc. as
synonmyms.
Which way of specifying the keys do you prefer?
Personally, no matter. Programming clarity should be kept at most - so it's
up to you. When some samples are provided, someone will follow them.
I will provide a more detailed example.

Re: [NTG-context] Proposal for math mappings

** Aditya Mahajan [2010-12-09 23:49:26 -0500]:
This is a proposal for a new way of selecting math mappings in MkIV. I want
to get input from other math users whether this syntax would take care of all
scenarios or not.
There are five different ranges in mathematics:
- digits (0..9)
- lower case Latin (abc..z)
- upper case Latin (ABC..Z)
- lower case Greek (αβγ..ζ)
- upper case Greek (ΑΒΓ..Z)
Should be: αβγ..ω
and ΑΒΓ..Ω
Thanks. I need to learn my Greek :)
A user may want to control what each range is mapped to. So, I suggest a setup
command
\setupmathmappings
[
digits={style,alternative},
lclatin={style,alternative},
uclatin={style,alternative},
lcgreek={style,alternative},
ucgreek={style,alternative},
]
where the options for style are
normal, bold
while the options for alternative are
normal, italic, sans, sansitalic, blackboard, script
This command will the mappings for each range. **NOTE**: All combinations are
not valid.
A companion command
\definemathmappings
[whatever]
[]
can be used to define multiple mappings. These mappings can be used by
\setupmathmappings[whatever]
(An alternative is that these mappings are activated using \whatever ...)
For example, we can define a command to typeset vectors using
\definemathmappings
[vectors]
[ digits={bold,normal},
lclatin={bold,normal},
uclatin={bold,normal},
lcgreek={bold,normal},
ucgreek={bold,normal}]
\def\VEC{\groupedcommand{\setupmathmappings[vector]}{}}
Is it should be
\def\VEC{\groupedcommand{\setupmathmappings[vectors]}{}}
?
Indeed. Thanks.
If later, we want to represent vectors as sans serif, we can use
\definemathmappings
[vectors]
[ digits={normal,sans},
lclatin={normal,sans},
uclatin={normal,sans},
lcgreek={normal,sans},
ucgreek={normal,sans}]

IMHO, style is already used so it is normal.

12 valid options
normal, italic, sans, sansitalic, blackboard, script,
bold, bolditlaic, boldsans, boldsansitalic, boldblackboard, boldscript
This very depends on used fonts.
I am assuming a complete opentype math font.
with the variants sansitalic-italicsans, boldsans-sansbold, etc. as synonmyms.
Which way of specifying the keys do you prefer?
Actually I don't get what you try to do.
I'll try to explain better in a later post.
I thought that 'font
switching' command should take care of font switching either in math or
text modes (if typescript is set properly).
I am proposing to separate out math font switching from text mode font
switching.
Right now the only good
example of usage of proposed mechanism is \VEC command (for vectors and etc).
More on this later.

Re: [NTG-context] Math and bold font
Hello,
thanks for the explanation -
On Sat, 04 Dec 2010 09:55:25 +0100, Hans Hagen pra...@wxs.nl wrote:
On 3-12-2010 5:00, Procházka Lukáš Ing. - Pontex s. r. o. wrote:

In fact in math these are not font switches, but switches to a different
alphabet. In traditional tex that normally is a font switch so one gets
the other bold or whatever shapes for free, given that they are in that
font (so it's a side effect of the way math alphabets are implemented),
but not so in open type math.
there is no default math font in mkiv: one uses regular math or bold
math (given that there are two font(set)s available which is seldom the
case) and within them gets bold or heavy alphabets (plus a few chars)
- So does it mean that the Vladimir's cambria case is exactly the seldom case
when regular and bold math are available, both defining Greek chars like \alpha as well?
\setupbodyfont[cambria]
\starttext
This is a test.
$a=\alpha$
$\bf a=\alpha$
$\bi a=\alpha$
\stoptext
Please, could you give more examples of normal and bold math fonts of the same
kin (to be used for normal and bold math), both having Greek letters as well?
- Vladimir showed cambria. Unfortunately, his solution changes the entire
document bodyfont (i.e. non-math font as well).
- What is the relationship to AMS fonts
(http://www.ams.org/publications/authors/tex/amsfonts)? Or how to make them
accessible in Ctx document? How to make them work?
- - On the site it's written: ... What is AMSFonts? ... *Subscript sizes of bold
math italic and bold Greek letters* ... Because these fonts are standard TeX fonts, they
may be used with any standard TeX system ...
- - Wouldn't this be exactly what I'm looking for?
Maybe \setupformulas[What to come here?] should do this? And what
\definetypeface[What arguments?] should precede?
best try to convert to the unicode math approach: bold a-z is different
unicode slots than a-z and in context the \bf command does that
transformation on ascii a-z (you can also key in the official unicode
chars); the benefit is that you can cut and paste the bold characters in
pdf files i.e. you retain that property; a bold b is not a bold one in
typographic sense but a special symbol that happens to use a bold
rendering; in for instance a section title, one can have all math bold,
and then this regular bold character will become real bold
Hans
I guess this approach won't be useful in my situation. I need to generate some
math by Lua. There is a function that should generate a context formulas with
mixed case and/or Greek letters, e.g.:
function t(var)
context($ .. var .. \\alpha = {\\bf .. -- Or something else instead of
bf
var \\alpha})
end
t(Abc)
So the variable name a priori cannot have information whether or not to be
printed with regular or bold math - this is up to the function 't()'.
---
Now I'm trying to understand This Way (11/2003, mag-0005.pdf) where the mixed case is investigated. Also
the co-fonts.pdf; but it seems to me that this document is a bit out-of-date and mfonts.pdf
should be used instead. And also Mojca's presentation from Brejlov, the some-thoughts-about-typescripts.pdf.
To be honest, I have a bit mess with fonts: I'm trying to deduce the
relationship between:
font script (text/script/scriptscript?),
font typescript (serif, sans-serif, math, mono, other?),
font size [marking] (xx/x/?/a/b/c/d/e; ?/xsmall/small/?/?...?, 5pt,
6pt... 40pt; ... at 6pt, ... at 20pt...; sixpoint,eightpoint,tenpoint... used in some
commands),
font weight (light? semilight? normal/semibold/bold/extrabold?),
font family,
font typeface
- When I look at the Figure 1 The current bodyfont environment in mfonts.pdf,
I see:
\showbodyfontenvironment % [lbr]
[lucida] [11.0pt]
text script scriptscript x xx small biginterlinespace
20.7pt 14.4pt 12pt 17.3pt 14.4pt 17.3pt 20.7pt not set
17.3pt 12.1pt 8.6pt13.8pt 10.3pt 13.8pt 20.7pt not set
...
So what's the relationship between text, script, scriptscript (and?) x, xx,
small and big?
Why size for the script on the first line is the same for xx, text as for big and
x the same as small?
Why doesn't work the same on the next lines as well?
- The abbreviations for [typefaces?]:
rm = ? RoMan? (means serif) (but also wrong Regular Math comes to
place)
ss = Sans Serif
tt = TeleType (but means Mono as well)
mm = Math what? MatheMatics? (used for typesetting inside $...$)
- When I call \definetypeface[whow][rm][serif][modern][computer-modern][encoding=ec] (mfonts.pdf, pg. 10),
why the arguments are rm and serif, although they mark (?) the same [script/shape]?
- - Why once modern and once computer-modern?
- When I call (mag-0005.pdf, pg. 4):
\definetypeface [mainface] [mm] [bfmath] [lucida] [default]

[NTG-context] Strange behavior of '\setupmathematics' and '\iint'
Hi.
I faced with strange (for me) behavior of combination of
'\setupmathematics' and '\iint'. Consider the following example:
example name=ex1.tex
\setupbodyfont[xits]
\setupmathematics[integral=displaylimits]
\starttext
This is a sample.
\startformula
\exp^{\imath\phi}=\cos\phi+\imath\sin\phi
\stopformula
\startformula
\int_{a}^{b}f(x)\text{d}x=F(x)+C
\stopformula
\startformula
\iint_{D}f(x,y)\text{d}x\text{d}y=\mu(D),\quad\text{here $\mu$ is a measure}
\stopformula
\stoptext
/example
If I comment line with '\etupmathematics' then I could compile the
example without error. The shown example however gives error when
compiled by context (mkiv):
error
! Missing } inserted.
inserted text
}
to be read again
$
\stopdisplaymath -\stopinnermath $
$\par \afterdisplayspace \par \egroup
\dostopformula ...eter \c!alternative \v!formula }
\dostoptagged \dostoptagge...
l.21 \stopformula
?
/error
Does this mean that 1) something wrong with font setup? 2) mathematics setup?
P.S. I took fonts (symlink) from TL2010 installed in parallel.

Re: [NTG-context] Using fourier-GUT as math font

problem as before:-(
It does not work that way in mkiv.
(1) you need a proper serif definition:
\starttypescript [serif] [utopia] [name]
\definefontsynonym [Serif][file:whatever.afm]
\definefontsynonym [SerifItalic] [file:...]
\definefontsynonym [SerifBold][file:...]
\definefontsynonym [SerifBoldItalic] [file:...]
\definefontsynonym [SerifSlanted] [file:...]
\definefontsynonym [SerifBoldSlanted] [file:...]
\stoptypescript
(2) you need a math definition:
\starttypescript [math] [fourier]
\loadfontgoodies[fourier-math]
\definefontsynonym[mathroman][four...@fourier-math]
\stoptypescript
(3) now you can define a typeface:
\definetypeface[whatever][rm][serif][utopia] [default]
\definetypeface[whatever][mm][math] [fourier][default]
\setupbodyfont[whatever]
However, first you need to figure out the right names for the utopia
files. Next you need to make a file fourier-math.lfg, like:
return {
name = fourier-math,
version = 1.00,
comment = Goodies that complement fourier math.,
author = Hans,
copyright = ConTeXt development team,
mathematics = {
mapfiles = {
fourier.map,
},
virtuals = {
[fourier-math] = {
{ name = futmi.tfm, vector = tex-mi },
{ name = futmii.tfm, vector = tex-it },
{ name = futsy.tfm, vector = lbr-sy, skewchar=0x7F,
parameters = true },
{ name = fourier-mex.tfm, vector = tex-ex,
extension = true },
}
}
}
}
This does not work at my end as the names of the files are wrong. Also,
more entries are needed (see for instance lucida-math.lfg). I have no
time to figure out these names.

that are erroneously have similar file names (with different extension)

Re: [NTG-context] A few puzzling problems (bugs?) with enumerations
Ok so after reading the source code of strc-des.mkiv, I found that
contrary to earlier documentation such as
http://www.ntg.nl/maps/36/09.pdf
it is not the 'number' parameter that should be used to share
numbering but the 'counter' parameter. After fixing that in my code,
theorems now have proper numbers and references to theorems work
properly too. However,
\starttheorem[number=no]
blah
\stoptheorem
and
\starttheorem[-]
blih
\stoptheorem
still don't work as expected inside sections, and I still have problem
1 listed in one of my previous emails, namely
Any ideas?
On a sidenote, I would like to contribute to the wiki or whatever is
the main documentation source of the ConTeXt project something to
document those parameters that are specific de \setupenumerations. The
context reference manual and the wiki both just refer to
\setupdescriptions yet there are a number of parameters that don't
exist for \setupdescriptions, such as number, counter, prefix,
prefixcomponents, etc.
Many thanks,
Mathieu

I see five problems :

Judging by Aditya's code in his MyWay on theorems, it used to be that
when there is no title, the parens don't appear. How do I recover this
behaviour?
2. I want the theorem enumeration to share its number with the
definition environment. That doesn't seem to work. Outside of any
section, the theorem just doesn't have any number. Inside a section,
the theorem very oddly displays the section number.
3. I want the proof enumeration to have no number. That doesn't
work inside a section. As for the theorem enumeration, the section
number is printed even though here i requested no number at all!
4. Suppressing the number for a specific enumeration using the [-]
switch doesn't work. As before, inside a section, the section number
appears instead of no number.
5. Citing a specific theorem using \in{theorem}[thm:pnp] doesn't show
the number of a theorem.
I'm guessing the last four points are all related.
