[squeak-dev] Greek letters and math equation displays

Looking around for this on the swiki, but couldn't find exactly how I
could display greek letters easily in squeak (that is for a
presentation). Also, would like to display math equations as well.

thanks much.

I guess we need a bit more information on your constraints. There are  
various ways, as you probably found out already. For example, one very  
easy way would be to make a screenshot of the equation you want to  
display, and drop it into Squeak ;)

E.g. does it need to work on all platforms? Does the font have to be  
in the image? Do you just want to display, or type, too? Which image  
are you using? Which VM? Etc. pp.

Until we have proper font and input support in a release it is  
somewhat complicated. Then of course it becomes easy.

One way I like particularly is this:

http://tracker.squeakland.org/browse/SQ-283

It's the result of a recent discussion on the etoys-dev list:

Note that the squeakland list you cc'ed is for Etoys users. To reach

that would be preferable since I'm creating at home and using the
school's computers for display

Yes, I'd like to be able to easily write it out in a text box, unless
there is an easier way.

>Which image are you using?

3.10, but I'll switch to whatever is best.

The one that comes with 3.10 on windows and mac (from the squeak.org site)

Ah.. thanks!


Any ideas on math equations?

In that case, see if this still works:

The above "hack" should allow this.

Hi Brad,

I wrote a LatexMorph a while back, to do exactly this.  It grabs the
output of Latex and displays it in a morph.  K K Subramaniam ("Subbu")
made extensive improvements, among others making it behave like a
proper EToy (which my version never did.)

I had a screenshot up at
http://www.tesujimath.org/squeak/LatexMorph

but you really should use Subbu's much improved version, at
http://www.squeaksource.com/LatexMorph/

Enjoy!

cheers,
Simon

THANKS!
