Thanks for the quick answer. I'm not completely sure about the "lua" files for math support that I should use as "template". The Palatino one I haven't found; The Garamond-math one might be that: "mdugm-math.lfg: return { name = "mdugm-math", version = "1.00", comment = "Math fonts that complement URW Garamond.", author = "Hans, Mojca, Aditya", copyright = "ConTeXt development team", mathematics = { mapfiles = { "mdugm.map", "mkiv-base.map", }, virtuals = { ["mdugm-rm"] = { { name = "file:ugmr8a", features = "virtualmath", main = true }, { name = "mdugmr7m", vector = "tex-mr", skewchar=0x7F }, { name = "mdugmri7m", vector = "tex-mi", skewchar=0x7F }, { name = "mdugmri7m", vector = "tex-it", skewchar=0x7F }, { name = "mdugmm7m", vector = "tex-bf", skewchar=0x7F }, { name = "mdugmmi7m", vector = "tex-bi", skewchar=0x7F }, { name = "mdugmr7y", vector = "tex-sy", skewchar=0x30, parameters = true }, { name = "mdugmr7v", vector = "tex-ex", extension = true }, { name = "mdugmrma", vector = "tex-ma" }, { name = "mdugmrmb", vector = "tex-mb" }, }, ["mdugm-bf"] = { { name = "file:ugmm8a", features = "virtualmath", main = true }, { name = "mdugmm7m", vector = "tex-mr", skewchar=0x7F }, { name = "mdugmmi7m", vector = "tex-mi", skewchar=0x7F }, { name = "mdugmmi7m", vector = "tex-it", skewchar=0x7F }, { name = "mdugmm7y", vector = "tex-sy", skewchar=0x30, parameters = true }, { name = "mdugmm7v", vector = "tex-ex", extension = true }, { name = "mdugmmma", vector = "tex-ma" }, { name = "mdugmmmb", vector = "tex-mb" }, } } } } 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. If you have other examples which I could be sure about, I'd be glad to have them. Regards, Chris On Tue, Jan 7, 2014 at 12:09 AM, Wolfgang Schuster wrote:

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.

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)

Hans

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"? Chris

You can also put the goodies files and the typescript file in the same folder as your test files which makes it easier to test them and to make changes. When you’re finished you can let us take a look at them and Hans can add them to the core.

Two files: kpfonts-math.lfg and testfile004.tex. It works rather well with the formulas of that file: https://github.com/khaledhosny/euler-otf/blob/master/tests/test.tex. Main issue: $\bf \Gamma$ produces "medium" \Gamma, though: ["kpfonts-bf"] = {... { name = "jkpbmia", vector = "tex-mr", skewchar=0x7F }, should make it bold. Why is this vector never selected? Other issue: Two consecutive \Gamma, are overlapping a lot. In case I add a vector for a script font which is in jkpsyd.pfb. What font switch would be used to select this vector (vector="tex-md")?

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. Wolfgang

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. Chris On Sat, Jan 11, 2014 at 7:36 PM, Elspeth McGullicuddy wrote:
