It's handled in the beta math module. There is also some info in
the chapter about fonts: \bf \mf etc try: 

$test \sin(x) \bf test \sin(x)$

The beta math module is also at 

	 http://www.cybercomm.nl/~bittext/temp

and it's called m-math.zip. But I'm afraid it still has a lot of bugs, 
and needs some support in the context core that is not there yet. 

As for the \ss stuff, this will have to wait until we can set up a new 
distribution when Hans is back.

bold math

[Mojca Miklavec]

Hello Hans,

I wanted to use

\definetypeface [boldmath] [mm] [boldmath] [latin-modern] [default]
\starttext
$\boldsymbol θ$
\stoptext

but it seems to fail in mkii and has no influence in mkiv. (The
workaround in mkii is to use \theta instead of θ, in mkiv it makes no
difference.)

1. Is there any simple patch that could make θ work in mkii? (I'm
working with mkii at the moment)
2. I have no idea what to do in mkiv case. Some of symbols (including
bold greek) exist is the same font, some don't and might require
another ("bolder") font. Maybe fixing the behaviour of \boldsymbol and
a few mappings for greek could be enogh to start with.

I have tried to enter "MATHEMATICAL BOLD ITALIC SMALL THETA" directly
with LM, but it didn't work (probably there are some mappings still
missing, but it's a bit uncomfortable to type proper mathematical
symbols anyway as editor is somehow lacking the characters and
keyboard would have to be reconfigured heavily).

Sorry, I take my word back. It works OK with \boldsymbol{θ}. However
the functionality in mkiv still needs to be fixed.

in mkiv (unicode) we need complete bold fonts .. (or make additional 
vectors); bold alphabets are part of math in unicode and should work ok 
but symbols is a 'whole font' issue

I agree ... there are lots of other symbols.

I noticed the "tex-bi" in math-vfu (I'm still looking into beta
version). There's no mapping for it, but I guess that it's probably
exactly the same as "math-bi".

Do you plan to misuse "tex-bi" or to to define mathematics.make_font (
"lmroman10-boldmath" ... ) for bold math then?

currently only math tf is defined (fam 0) and we will also have math bf 
(fam 1); mostly a matter of definitions but i was not in the mood to 
figure out all the bold fonts involved/needed

sure, which is why most symbols have names too; i expect lm typewriter

For MKII, define

\definetypeface [boldmath] [mm] [boldmath] [latin-modern] [default]

and then use \boldsymbol around symbol that you want in bold.

For MKIV, bold math isn't handled yet.

I do not know of fonts that provide calligraphic and doublestroke symbols. 
Calligraphic uppercase letters, and doublestroke letters are provided by 
ams fonts, and can be used using

{\cal ABC} {\Bbd ABC}

without requiring any extra setup.

I don't know how to get them in the standard cmr fonts, but I have the 
lucida fonts installed and realised these bold characters as follows:

\definetypeface [mainface] [rm] [serif]       [lucida] [default] 
[encoding=texnansi]
\definetypeface [mainface] [tt] [mono]        [lucida] [default]

\definetypeface [mainface] [mm] [math,bfmath] [lucida] [default] 
[encoding=texnansi]
\setupformulas [method=bold]
\usetypescript [lucida] [texnansi]
\switchtotypeface  [lucida] [12pt]

bold math

[Adam Lindsay]

[-- Attachment #1: Type: text/plain, Size: 1452 bytes --]

Hi all.

I've revisited the euler support scripts with an eye towards bold math. I
think I have it right now.

I tried applying the same techniques to computer-modern math in order to
get bold math going for the TeX default font, and it seems not to switch
back to the right font after a grouped \bfm font switch. The minimum case
for this is $x{\bfm x}x$, which gives an italic x, a bold x, and then a
roman x.

Hans (others with full Lucida math?), what does the test case look like?

If you want to try the attached typescript, the following should work well:
\definetypeface[mainface][mm][math][euler][euler]
\definetypeface[mainface][mm][bfmath][euler][euler]
\definetypeface [boldmath][mm][boldmath][euler][euler]
\definetypeface [boldmath][mm][bfmath][euler][euler]

The following fails on cases like the one I described, but is reasonable
otherwise:
\definetypeface[mainface][mm][math][computer-modern][computer-modern]
\definetypeface[mainface][mm][bfmath][computer-modern][computer-modern]
\definetypeface [boldmath][mm][boldmath][computer-modern][computer-modern]
\definetypeface [boldmath][mm][bfmath][computer-modern][computer-modern]

bold math

[Sytse Knypstra]

Ahoj,

On November 11 I asked the list how I could generate bold greek math 
symbols (I have the lucida family installed).
Until now I didn't get a response, so maybe I should be more specific.

Let me put it this way:
On page 12 of the `Fonts in ConTeXt' manual I find the footnote:
`Bold math is already prepared in the core modules, so normally one can do 
with less code.'

Can anybody tell me what code I have to add and where?
I would like to get the following line
$\theta = {\bfmath \alpha' x}$
with \theta in normal math and \alpha and x in math boldface?

First of all, the definition of \bfmath is broken (i probably never really 
tested it)

\def\bfmath{\bf\mf\synchronizesymb\mf}

i'll come back to more advanced mixed normal/bold switching later (playing 
a bit with that now);

a main switch to bold math is best done with a new typeface:

bold math

[Sytse Knypstra]

Hi all,

I would like to use bold greek math symbols (I have the lucida family 
installed).
In the `Fonts in ConTeXt' manual I concluded from page 12 that this should 
be relatively simple.
However all my attempts failed: either I got the normal math symbols or I 
got all (roman and greek) symbols bold,
whereas I want to use them alternately.
I tried the description on the pages 13 and 14, but I couldn't get it working.
I simply inserted `,boldmath' in the lucida typescript in the file type-exa 
and it gave me all symbols bold.
I must admit that I don't understand much of what is written in the `Fonts 
in ConTeXt' manual.

Can anybody give me a solution of how to achieve this?

BTW. Shouldn't this feature be a standard one in ConTeXt?

Thanks
Sytse

    ConTeXt  ver: 2000.5.29  fmt: 2000.9.5  int: english  mes: english
and it doesn't work yet.
It is very important feature for me.

Many thanks

Probably not. \boldsymbol (as well as \boldmath) depend on font mapping 
definitions of the five extra fonts, as in this example for Lucida:

\definefontsynonym [ExtraMathRoman]          [LucidaBright-Demi]
\definefontsynonym [ExtraMathExtension]      [LucidaNewMath-Extension]
\definefontsynonym [ExtraMathItalic]        
[LucidaNewMath-AltDemiItalic]
\definefontsynonym [ExtraMathSymbol]         [LucidaNewMath-Symbol-Demi]
\definefontsynonym [ExtraMathAlpha]          [LucidaNewMath-Arrows-Demi]

For Computer Modern, it would be something like this (untested):

\definefontsynonym [ExtraMathRoman]          [cmbx10]
\definefontsynonym [ExtraMathExtension]      [cmex10]
\definefontsynonym [ExtraMathItalic]         [cmmib10]
\definefontsynonym [ExtraMathSymbol]         [cmbsy10]
\definefontsynonym [ExtraMathAlpha]          [msam10]

If you add these commands to the top of your input file, \boldsymbol
*should* work

Taco is the expert here, but did you load the math fonts that
are needed?

Hans is right. Look into the source of m-math, and search for
"boldmath".  This part really needs core context support to work,
which will be added after the merge of the module.

[Matthew Baker]

Hi all,

Just received my shiny new Lucida Bright & Lucida Math font CD yesterday.
How do I do bold in math mode?  I want the bold math font, ie
LucidaNewMath-Demi or whatever it's called.  If I do \bf in math mode I
get bold roman.  If I do \bi I get regular bold italic, not bold math (so
$\bi ff$ gives the wrong thing, for example.  In Latex I have a macro

\newcommand{\mbf}[1]{\mbox{\boldmath $#1$}}

Is there already a switch in Context to activate the correct font?  If
not, how do I set one up?

Thanks.

- Matthew

Matthew,

You need to read the manual ;-(

Search for the meaning of \mf

I couldn't find any mention in either of the manuals but my Dutch isn't
good so maybe I missed it.  In any case, $\mi\mf$ seems to be what I'm
after.  Thanks.  I figured there must be a command like that somewhere.

There are some examples in the big dutch beta one? Do you have that one?
I'll send you a typeset docu file of font-ini. Tells it in english.

Ah, the beta version.  I read the older (even bigger) version.  The
typeset font-ini makes it clearer though, thank you.  However I still have
some difficulties.  To get something in bold math font, I do
something like

$ ... {\bi\mf x} ... $

Is this correct?  For x that works fine.  However,

$ ... {\bi\mf ff} ... $

gives the wrong thing.  In cmr, the spacing between the fs is simply too
small.  In lbr I get something very strange indeed (a ligature that isn't
in the font?).  Also I'm guessing

$ ... {\bi\mf\sigma} ... $

should give me a bold italic sigma in lbr.  It's just a regular (unbold)
sigma though.  This works correctly in pdflatex so the character is
definately there and pdftex can find the font ok.

Actually these bold greek letters are one of the major reasons I bought
the Lucida font set.  I keep having to typeset variance vectors :)

Spacing in math is different. Just put a \hbox around it.

Ah, but i'm not sure if they are already defined in context. I'll see if
I can find myself the fonts (must be somewhere on my computer I think). 

Math is a bit problematic anyway, due to the lack of families in tex and
the fact that the last font switch dominates all, a (mis)feature of tex
(sideeffect actually).
