Hi all,
This is to announce that the latest beta supports creating virtual math
fonts with fallback. The main test case is to use Euler font with missing
characters taken from Pagella but the mechanism is general and can be used
to replace a specific set of math glyphs from a font.
This feature is not extensively tested. As such it will be useful if
everyone interested in math fallback mechanism could test this out and
report any bugs or inconsistencies.
To use this feature you have to use `pagellaovereuler` as your math font.
For example, to use Euler with DejaVu fonts, use:
\usetypescriptfile[euler]
\starttypescript[mainface]
\definetypeface[mainface][rm][serif][dejavu] [default]
\definetypeface[mainface][ss][sans] [dejavu] [default]
\definetypeface[mainface][tt][mono] [dejavu] [default]
\definetypeface[mainface][mm][math] [pagellaovereuler][default]
\stoptypescript
\setupbodyfont[mainface]
\appendtoks \rm \to \everymathematics
\setupmathematics
[lcgreek=normal, ucgreek=normal]
There is a built-in typescript `euler-with-pagella` to use
`pagellaovereuler` as the math font and `pagella` as the text font.
If you are interested in implementing similar fallback mechanisms for
other fonts, see type-imp-euler.mkiv and euler-math.lfg for details.
Aditya

I would like to test and hopefully use this setup for _Street-Fighting Science and Engineering_. It should also give the setup a thorough workout. But I can't quite get the preamble right. The test file below typesets text and math in palatino. \usetypescriptfile[euler-with-pagella] \definebodyfontenvironment[10.5pt] \setupbodyfont[palatino,10.5pt] \starttext \input knuth \placeformula\startformula a^2 + b^2 = c^2. \stopformula \stoptext If I add \appendtoks \rm \to \everymathematics \setupmathematics[lcgreek=normal, ucgreek=normal] just before \starttext, the math is typeset in roman pagella. What am I doing silly? Also, one of my reservations about using Euler for math, which readers complained about in _Street-Fighting Mathematics_, is that v and \nu (kinematic viscosity) look so similar. Do you know any way to make them more distinguishable, e.g. by substituting a different character? -Sanjoy > To use this feature you have to use `pagellaovereuler` as your math font. > For example, to use Euler with DejaVu fonts, use: > > > \usetypescriptfile[euler] > \starttypescript[mainface] > \definetypeface[mainface][rm][serif][dejavu] [default] > \definetypeface[mainface][ss][sans] [dejavu] [default] > \definetypeface[mainface][tt][mono] [dejavu] [default] > \definetypeface[mainface][mm][math] [pagellaovereuler][default] > \stoptypescript > > \setupbodyfont[mainface] > > \appendtoks \rm \to \everymathematics > \setupmathematics > [lcgreek=normal, ucgreek=normal] > > > There is a built-in typescript `euler-with-pagella` to use > `pagellaovereuler` as the math font and `pagella` as the text font. ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 15+ messages in thread

You are right. I am not sure what I had done, but it works as you say. I also put the font setup in an environment file that is loaded by testproject.tex, and that also works. \project testproject \startcomponent test \input knuth \stopcomponent Because of font loading, is this recommended way to use components (rather than the old way of the \project line after \startcomponent)? If so, I'll make a note on the wiki. -Sanjoy ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 15+ messages in thread

Yes. This is one of the changes from MkII to MkIV. I think that Hans had a This Way document on this.

This does not only apply to component etc. but also to normal files because context sets and resets some values with \starttext etc. and to avoid some problems it’s better to put all setup commands before it.

Agreed. The wiki page for "Project Structure" has always shown setups (via \project ... ) going after the \startcomponent or \startproduct. I've edited the examples to have setups before the \start(product|component). If I did it wrong, let me know. -Sanjoy ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 15+ messages in thread

My change doesn't work, because of how components handle project files (which also turns out to explain why I was seeing the Euler font when you didn't). The problem is that context doesn't generate a pdf file if the \project line comes before the \startcomponent. Thus, I was seeing a pdf file from a previous version of the test file (where the font setup came after the \startcomponent). Here are the two test files (testproject2.tex and test6.tex): ==== testproject2.tex ============ \startproject testproject \stopproject ================================== (If testproject2.tex is empty, then the problem does not occur.) ========== test6.tex ============= \project testproject2 \startcomponent test \input knuth \placeformula\startformula a^2 + b^2 = c^2 \stopformula \stopcomponent ================================== Here is the log file. It says 'result saved in test6.pdf' but no pdf file is actually saved.

One inconsistency or maybe bug is that text subscripts come out in Euler instead of Palatino. Here's an example (using 2014.02.14 beta). The "Sun" subscript using _{\tf Sun} or _{\rm Sun} was in Palatino in the corresponding MkII setup, but is in Euler now. The workaround of an hbox with \tfxx or \tfx doesn't get quite the right size. \usetypescriptfile[euler] \definetypeface [mainface] [rm] [serif] [pagella] [default] \definetypeface [mainface] [tt] [mono] [dejavu] [default] [rscale=0.9] \definetypeface [mainface] [mm] [math] [pagellaovereuler] [default] \setupbodyfont[mainface] \appendtoks \rm \to \everymathematics \setupmathematics[lcgreek=normal, ucgreek=normal] \starttext \placeformula\startformula M_{\rm Sun}\quad M_{\hbox{\tfx Sun}} \quad M_{\hbox{\tfxx Sun}} \quad M_{\tf Sun} \stopformula \stoptext ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 15+ messages in thread

I agree about \rm. However, _{\tf blah} once (in MkII) selected the text font. e.g. \starttext \placeformula\startformula M_{\tf Sun} \stopformula \stoptext Is the II->IV change in \tf semantics intended? It's not hard to adjust for by using 'sed'. I raise the issue only in case the change is not intended. Actually, the example just as above (i.e. using modern fonts) works fine works in MkII and MkIV. It also works if "\setupbodyfont[palatino]" is inserted as the first line. It's fails only when using Palatino with Euler (at least, in the way that I did it). That data doesn't say what the right behavior is. But it may help you decide. -Sanjoy ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 15+ messages in thread
