Stef if you loaded STickySq in Pharo I cannot guarantee to work properly because one difference between the Pharo an Squeak are some removed keyboard hooking methods in HandMorph.

Re: [Pharo-project] [squeak-dev] [ANN] STicky

by HernÃ¡n Morales Durand

That's one idea. Although there are many applications. I'm using it now to test a translator from Smalltalk to PQF (an insane query language), but the course of acquisition of a natural language is a very complex process, so a linguist can write a translator which display dynamically inflectional systems differences between English and Greek or Chinese, or a WordNet application which suggest synonyms to a writer as he writes, or a logician which desires to show his students calculus applied to a "lingua characteristica", i.e. it is not limited to computer or constructed languages. Use your imagination :) For the Smalltalk to Java part, I've just included a translator available in the SqueakSource repository, I'm not so concerned about the correcteness of a translator but if the author wants to include a warning before usage of his tool I will happily include it. One motivation for STicky were the arguments of some Java developers I know, they told me they've felt lost inside Smalltalk (they've never seen a Programming System as an autonomic system with global behavior, etc. but as a process which deals with dead text code) and since language is a means for referring objects rather than the object itself, this tool can show the referent sources of their language, if a translator exists of course.

Hi Stef, STicky is for Pharo and STickySq is for Squeak. I've decided to provide two separate packages because it's easier for me to make changes in each ST separately, without worring about collateral consequences in another.
