Thanks for your reply Wolfgang. I use the minimals and have some
further questions:

1) Is there any way to use first-setup.sh to install these fonts?

2) The type1 dir is empty. Is that on purpose? Should one download the
pfb files from ctan?

3) Will there be any support of the Fourier fonts? I have asked this
before, sorry about that, but I'm kind of clueless about the present
situation.

Not so far. But you can always ask Mojca to include them in the minimals.

I do not use Fourier. I will check what is do we need to get them to work 
with MkIV. Usually, it is just a matter of creating a virtual font 
mappings in math-vfu.lua. But it is a time consuming and boring process.

At the moment there is a switch
    --extras=t-module1name,t-module2name

the following quick-and dirty patch should enable you to use
    --extras=mathdesign

But then you need to convince Hans to apply the patch (or maybe
improve it before that):

if extras and type(extras) == "table" then
    -- fetch the list of available modules from rsync server
    local available_modules = get_list_of_files_from_rsync({"modules/"})
    local available_fonts   = get_list_of_files_from_rsync({"fonts/extra/"})
    -- hash of requested modules
    -- local h = table.tohash(extras:split(","))
    for _, s in ipairs(available_modules) do
    --  if extras == "all" or h[s] then
        if extras.all or extras[s] then
            scripts.update.modules[#scripts.update.modules+1] = {
format("modules/%s/",s), "texmf-context" }
        end
    end
    for _, s in ipairs(available_fonts) do
        if extras.all or extras[s] then
            scripts.update.modules[#scripts.update.modules+1] = {
format("fonts/extra/%s/",s), "texmf" }
        end
    end
    -- TODO: check if every module from the list has been added and
issue warning otherwise
    -- one idea to do it: remove every value from h once added and
then check if anything is left in h
end

No, it was a mistake. I had a "fonts/*/public/mathdesign" in pattern,
but mathdesign is not under "public" in TeX Live. Either I didn't test
it properly or TeX Live has changed their location, but the first
option is way more probable.

I have a feeling that some other font has been requested recently, but
I don't recall which one/who wrote that (I don't find the mail any
more).

Re: Mathdesign and Fourier fonts (was What do you miss in ConTeXt?)

[Mikael Persson]

Thank you Mojca and Aditya for your answers,

I hope the mathdesign part of mtx-update.lua will end up in the
orignal file. I do not know how to use it now.

If I save this file and update with "sh firstsetup.sh --extras=all"
(or --extras=mathdesign) it seems that the mtx-update.lua is
overwritten with the version from the server. I do not know howto
upgrade with mtx-update.lua without firstsetup.sh.

About the fourier fonts. Is there a lot of work to do in math-vfu.lua
to get it to work? I looked into that file, but it was a bit hard to
understand what is needed...

Maybe it is hard work to get the fonts working, but I really think
that if we have several text+math fonts easily available in the
minimals that will make (new) users very happy.

it depends ... if the font is in tex default encoding then it's only a 
matter of adding a small table

I have now manually downloaded the mathdesign fonts (and the charter
fonts, not available on the server it seems)

The fonts gets used, but I get upright math letters instead of italic
ones. My test file is given by

\definetypeface[charter][rm][serif][charter]     [default]
\definetypeface[charter][mm][math] [charter]     [default]

\setupbodyfont[charter,10pt]

\starttext
We define, for real $x$, the absolute value of $x$ as
\startformula
|x|=
\startcases
\NC \hphantom{-}x \MC x\geq 0,\NR
\NC -x \MC x<0.\NR
\stopcases
\stopformula
Also let $\alpha$, $\beta$ and $\Gamma$ be\dots
\stoptext

The output can be found at

http://home.imf.au.dk/mickep/mdesign.pdf

Typesetting a similar document with LaTeX I get italic math (note also
that the \Gamma is upright, I guess that this is an option that is
turned on by default by LaTeX)

http://home.imf.au.dk/mickep/lmdesign.pdf

I guess this has something to do with the following lines in math-vfu.lua

mathematics.make_font ( "charter-math", {
    { name = "file:bchr8a", features = "virtualmath", main = true },
 -- { name = "md-chr7m.tfm", vector = "tex-mr" },
    { name = "md-chri7m.tfm", vector = "tex-mi", skewchar=0x7F },
    { name = "md-chri7m.tfm", vector = "tex-it", skewchar=0x7F },
    { name = "md-chr7y.tfm", vector = "tex-sy", skewchar=0x30,
parameters = true },
    { name = "md-chr7v.tfm", vector = "tex-ex", extension = true },
    { name = "msam10.tfm", vector = "tex-ma" },
    { name = "msbm10.tfm", vector = "tex-mb" },
} )

However, I am not able guess what to change (I tried different things
available in mdbch.map).

Any help is appreciated.

Mikael

Hans, Mojca, Aditya, Wolfgang and others

1) Can anyone confirm this problem in the previous mail or point out
what might be wrong?
2) The problem Troy had with lucida, is it the same?
3) What is needed to get fourier fonts working? Is it enough adding to
math-vfu.lua an entry like
mathematics.make_font ( "fourier-math", { ...
})
with the right names for fourier? I tried this, but no math fonts is
showing up in the pdf file. In what other file should I add changes.
I'm willing to do some trial and error to get it to work...

Best regards, Mikael

I cannot confirm since I get

Assertion failed: (l_fonts[1] != 0), function read_char_packets, file
../../../source/texk/web2c/luatexdir/font/luafont.c, line 881.
MTXrun | fatal error: no return code, message: luatex: execution interrupted

Might be related, but solving one won't solve the other one.

If the font comes with some weird encoding, then you also need to
write the whole slot-to-unicode mapping.

See for example:

fonts.enc.math["tex-sy"] = {
    [0x0002D] = 0x00, -- -
    [0x02212] = 0x00, -- -
--  [0x02201] = 0x00, -- complement
--  [0x02206] = 0x00, -- increment
--  [0x02204] = 0x00, -- not exists
--~     [0x000B7] = 0x01, -- cdot
    [0x022C5] = 0x01, -- cdot
    [0x000D7] = 0x02, -- times
    [0x0002A] = 0x03, -- *
    [0x02217] = 0x03, -- *
    [0x000F7] = 0x04, -- div
    [0x022C4] = 0x05, -- diamond
    [0x000B1] = 0x06, -- pm
    [0x02213] = 0x07, -- mp


There is

mathematics.make_font ( "charter-math", {
    { name = "file:bchr8a", features = "virtualmath", main = true },
 -- { name = "md-chr7m.tfm", vector = "tex-mr" },
    { name = "md-chri7m.tfm", vector = "tex-mi", skewchar=0x7F },
    { name = "md-chri7m.tfm", vector = "tex-it", skewchar=0x7F },
    { name = "md-chr7y.tfm", vector = "tex-sy", skewchar=0x30,
parameters = true },
    { name = "md-chr7v.tfm", vector = "tex-ex", extension = true },
    { name = "msam10.tfm", vector = "tex-ma" },
    { name = "msbm10.tfm", vector = "tex-mb" },
} )

But I'm not sure if all of the fonts are right (I need to figure out
how to compile the example in the first place). A way to check is to
run the following with MKII and compare both for example:

\showfont[md-chr7m.tfm]
\showfont[rm-lmr10]

Re: Mathdesign and Fourier fonts (was What do you miss in ConTeXt?)

[Mojca Miklavec]

But I realized that there's another problem anyway. At least for MKII
ConTeXt wants to use ec-bchr8a.tfm and that file is not present in the
package.

This means that either:
- one needs to provide new tfm files
- one needs to fix the typescripts
