oh Sean this so beautiful and elegant, exactly what I was looking for. Thank you very much. The rest of your code is what I was thinking doing with regex instead.

Re: [Pharo-users] Notebook/slideshow morph

by Offray Vladimir Luna CÃ¡rdenas

Hi Blake, One of the first things I did on Squak/Etoys as a presentation... looong time ago[0], but I think it can be opened again in current vms. Now I'm doing some kind of notebook in Moose and scholarly markdown, but they are not for slides, but more related to book alike documents, links about this alternative approach to documentation can be found on [1][2][3][4][5].

Instead of Pillar it uses pandoc's markdown[3][4][5], which I think could have more early adopters, but may be can be helpful in someway for what you're looking for.

Re: [Pharo-users] Pharo / J - Integration

by Martin Saurer

Hi Torsten To re-implement APL or J capabilities in pure smalltalk is an interesting approach. The problem I see currently is the performance when handling large arrays with thousands or millions of rows and/or columns. During some performance tests I saw that for arrays with a few hundred rows/cols, the calculation speed of Pharo and J is nearly the same. When handling arrays with thousands or a few millions of rows/cols, J is 7-10 times faster than Pharo. During the last decades, J has been optimized explicitly to handle (very) large arrays. In my opinion, it would be difficult to get the same processing speed in pure smalltalk. That's not a disadvantage of smalltalk, it's simply the nature of different languages.
