Re: [Pharo-users] Simple math editor/typesetter

by Nick Chen

Thanks for pointing out Google infographics; didn't know that it could also display equations. Preferably, I would like it to display using Morphs so that I can have more options for interactivity e.g. editing and drag-and-drop. I already have a parser implemented; this whole thing is part of a bigger project and I'm working on the display part currently. What happens in Pier-Math? I only know that Pier is a CMS on Seaside so I'm not too familiar with the internal details. I assume that Pier-Math has some parser and renders to HTML (perhaps using MathML or something). Does it render to Morphic? Are there any existing things that can render using Morphic directly in the Smalltalk image? Thanks. -- Nick Lukas Renggli wrote: > > On 11 September 2011 18:51, Lukas Renggli <renggli(a)gmail.com> wrote: >> The Google infographic web service is probably the simplest one to use >> (there are many others): http://code.google.com/apis/chart/infographics/ >> You post a formula and get back a PNG that you display as a morph.

Re: [Pharo-users] Simple math editor/typesetter

The Google infographic web service is probably the simplest one to use (there are many others): http://code.google.com/apis/chart/infographics/ You post a formula and get back a PNG that you display as a morph. Should be doable in 1 line of Smalltalk code. Of course you can do the processing also yourself, but this is more complicated. Pier-Math does that for example.

Simple math editor/typesetter

by Nick Chen

Hi I'm working with some simple math equations and am looking for a nicer way to display them. Is there any existing work that I might be able to re-use/build upon? For instance, given this equation, (1+2/3)*4 I would like to see it displayed like the Equation Editor in Microsoft Word or the equations in a Mathematica notebook. See attached screenshots: http://forum.world.st/file/n3805250/word.png http://forum.world.st/file/n3805250/mathematica.png I'm not looking for anything fancy. Something simple to get me started would be helpful as well. I looked briefly at Dr. Geo but I don't think it support displaying equations in that manner. Thanks! -- Nick -- View this message in context: http://forum.world.st/Simple-math-editor-typesetter-tp3805250p3805250.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

New version of Little Number Chapter

by StÃ©phane Ducasse

Hi guys I took into account the remarks of mariano and I imagine that the chapter improved. It can be obvious for some people but I like to make sure that we all find this obvious. Because it is not difficult once you spend a little time on it. Now if somebody wants to extend and improve, he/she welcome. I will continue to work on the others chapters. Stef A guy that truly believe that software is only done when the documentation is packed too.
