Hi all. I was wondering if anyone else was interested in the Euler math font. I was a bit frustrated in its incomplete coverage of certain symbols (e.g. delimiters, radicals), but then I discovered the Virtual Euler Math fonts/eulervm for LaTeX. It yields a set of virtual fonts (zeu*.vf) that make the glyph set look a lot like the default computermodern math fonts. <http://www.ctan.org/texarchive/help/Catalogue/entries/ eulervm.html?action=/texarchive/fonts/> I've come up with a math collection (mathzeu) and a combined typescript file (typezeu) that seem to give good enough results. Does anyone do enough math typesetting to want to test "zeuler" out? I've gotten good enough results this evening, but I don't have a lot of sophisticated formulae lying around to do a full test. Does anyone have some semi demanding (nonAMSterritory) math for me to try?

The continuation method involves taking a small step $\dlambda$ in $\lambda$ and solving for the increment $\dvx$ in $${d\vh\over d\lambda}\,\dlambda + \jac\,\dvx =0,\eqno{(9)}$$ where $J=(d\vh/d\vx)$ is the Jacobian of $\vh$ with respect to $\vx$. The updated solutions $\vx'=\vx+\dvx$ will not be exact if we are taking finite steps, so one needs to use Newton's method to improve their accuracy. \end % It works for me using cm* fonts.

Many thanks, Guy. The accents (e.g., \qtr) are definitely going to take some work, and the BoldMath switching is also going to take a bit of learning, but the file runs very well.

Thanks for reminding me about that. Yes, so as I suspected, the accents presented a problem. The virtual euler didn't include them, and ConTeXt seems to depend on a sensible (math) roman being defined. I brought in Bitstream Charter as my (fake) MathBeta font to help out with those definitions. Charter and Euler seem to be very nicely matched in proportions and stroke weight. You can see the results here: http://homepage.mac.com/atl/tex/eulerism.pdf (81kb) There is no euler varrho or varsigma, so they point to the normal variants. Supporting Guy's test file is still going to be a struggle, since it's mostly Plain TeX (which I'm nearly clueless about), and it uses the quaternion(?) accent (\qtr).

concerning combinations, maybe make typescripts for them, so that we got nicely matching sets for relative scaling parameters, there are test macros like: \showfontstrip \testminimalbaseline \showminimalbaseline Hans  Hans Hagen  PRAGMA ADE  pragma@wxs.nl Ridderstraat 27  8061 GH Hasselt  The Netherlands tel: +31 (0)38 477 53 69  fax: +31 (0)38 477 53 74  www.pragmaade.com  information: http://www.pragmaade.com/roadmap.pdf documentation: http://www.pragmaade.com/showcase.pdf

Gladly. That makes the most sense. I believe Otared's example illustrates that CM is not the best match with Euler. Any suggestions beyond my beloved Charter? However, my use of Charter is before typescripts... it's to bring in accents that have a similar stroke width to Eulereven though CM is used to create the virtual font, CM's accents are far too spindly.
for relative scaling parameters, there are test macros like:
\showfontstrip
Again, thanks for the hint on when to use that command. It's very interesting to compare with my eyedriven guesses. Cheers, adam  ============================== Adam T.

I've had a look at your pdf, chironeu.pdf, and was startled at how informal it looks compared to when it's typeset with mathtimes. In LaTeX, I've seen Euler mixed with Palatino (in the package mathpazo), where Palatino is typeset with an extra 5% leading. I've also seen it typeset with Pandora. I liked the way it mixed with Pandora.

There is no euler varrho or varsigma, so they point to the normal variants.
Supporting Guy's test file is still going to be a struggle, since it's mostly Plain TeX (which I'm nearly clueless about), and it uses the quaternion(?) accent (\qtr). I have no clue where in ConTeXt that's defined. Similarly with the bold mechanism with \vct.
So. More test docs wanted. :)

Hi Adam, I tried your files included in zeuler.zip with ConTeXt on several maths examples, and now all the characters, are present and work fine, including the accents. Many thanks for doing such a useful work! Cheers: OK On mercredi, jan 29, 2003, at 19:39 Europe/Paris, Adam Lindsay wrote:
Hi Otared.
Many thanks for testing that. I noticed the missing varrho & varsigma, and have since replaced the normal variants. I've also updated the accents to pull them from Charter.
You, and others, can pull the latest version of this from: http://homepage.mac.com/atl/tex/zeuler.zip (6KB) Documentation, as always, will come later. ;)
Cheers, adam

in matheul you define a lot, like sin/cos etc this can be left out (saving mem and hash space) since default is the fall back So, the eul math file can be much smaller; i could look into it, but you robably know best what should be left in there typescripts look ok, so when you declare things ok, i can add those snippets to the main type* files; how about using [euler] instead of [zeuler] Hans  Hans Hagen  PRAGMA ADE  pragma@wxs.nl Ridderstraat 27  8061 GH Hasselt  The Netherlands tel: +31 (0)38 477 53 69  fax: +31 (0)38 477 53 74  www.pragmaade.com  information: http://www.pragmaade.com/roadmap.pdf documentation: http://www.pragmaade.com/showcase.pdf

Wasn't sure it worked that way. Over the past few months of experimenting with ConTeXt, I've learned to do things as verbosely as possible, and then reduce as suggested by more knowledgeable sources. I'll experiment on cutting down.

Yup. I'll work on it.
typescripts look ok, so when you declare things ok, i can add those snippets to the main type* files; how about using [euler] instead of [zeuler]
I only did that to avoid clashing with the existing euler. If you're fine with requiring people to load eulervm (which is easy enough to obtain, true), then I'll be happy to prepare it to be a new default. Similarly, is the dependance on Bitstream Charter (for the textlike accents in math mode) desirable as a part of the main type* files? Thanks for the guidanceI'm a bit surprised by the interest! adam  ========================= Adam Lindsay +44(0)1524 594 537 atl@comp.lancs.ac.uk http://www.comp.lancs.ac.uk/computing/users/atl/ =========================

Oh, right, about those functions... I found that euler's characters are best set in isolation, and don't serve math functions very well. In the current document I'm setting, I've redefined mfunction to help relate math with the main text: \def\mfunction#1{{\em#1}} 1) is that the "right" way of doing it? 2) is it desirable to add to the definitions (where?) as a default? (I have \em set to italic, but others might prefer the default slanted.)  ========================= Adam Lindsay +44(0)1524 594 537 atl@comp.lancs.ac.uk http://www.comp.lancs.ac.uk/computing/users/atl/ =========================

since it's default mapping, a simple two entry math collection can solve that (map on placeholders) [off line now so cannot see 'm] Hans  Hans Hagen  PRAGMA ADE  pragma@wxs.nl Ridderstraat 27  8061 GH Hasselt  The Netherlands tel: +31 (0)38 477 53 69  fax: +31 (0)38 477 53 74  www.pragmaade.com  information: http://www.pragmaade.com/roadmap.pdf documentation: http://www.pragmaade.com/showcase.pdf 
Okay, after actually *looking* at the code definitions, I got a bit farther with Guy's test file. I might dabble with making a math bold out of what I have, but it seems to render okay with the vector "accents". I'm still not sure about the matching of the text height, but \showfontstrip definitely helps with that.

I was wondering if anyone else was interested in the Euler math font. I was a bit frustrated in its incomplete coverage of certain symbols (e.g. delimiters, radicals), but then I discovered the Virtual Euler Math fonts/eulervm for LaTeX.
Sounds great.
Does anyone do enough math typesetting to want to test "zeuler" out? I've gotten good enough results this evening, but I don't have a lot of sophisticated formulae lying around to do a full test. Does anyone have some semi demanding (nonAMSterritory) math for me to try?
Here's a script used to test the mathtimes fonts: (courtesy of YandY). I simply commented out the bits that were giving ConTeXt indigestion.
It works for me using cm* fonts.  ============================== Adam T. Lindsay atl@comp.lancs.ac.uk Computing Dept, Lancaster University +44(0)1524/594.537 Lancaster, LA1 4YR, UK Fax:+44(0)1524/593.608 =============================
I am still confused about how to use the typescripts to set up Euler. The file below, when processed, renders the warning 'unknown variant zeuler', and I get the wrong characters in math. That is, the left parenthesis is replaced by rightharpoonup and the right one by rightharpoondown. Could anyone give me guidance on how to use the math fonts?

Hello, Johannes, I think you're using an old version. This (attached) is what's on my machine right hereI think there's a newer version of the typescripts on another machine with Euler bold also enabled. Still planning on cleaning up and releasing a "My Way" on it. Johannes Hüsing said this at Sun, 30 Mar 2003 09:37:30 +0200:

After receiving advice from Hans, I've called the typescript "euler" and "eul" (in the attached). You need to make sure that the old matheul.tex is ignored and that the new one takes precedence.
Could anyone give me guidance on how to use the math fonts?
Using the attached scripts with the notated changes, it seems to work for me...

The more detailed typescripts are more for when you setup a whole typescript combining a roman font with the euler math font.  ============================== Adam T.
