What about the class definition format change described by Camillo? Thierry

Other MenuMorph facts

(MenuMorph selectors select: [ :each | 'add*' match: each ]) size 42 number of isKindOf: 11 for a single class I imagine that this is the top. Stef

Re: [Pharo-dev] Returning the source of a class as a string

by kilon alios

Oh yes yes thank you, thank you both, this is exactly what I wanted. No need to send me your code ,I can parse this with regex I am already parsing pharo code with regex and it has been easy enough. It worked for messages like unary and keywords but I wanted to do more complex pharo syntax parsing to python. But if your code follows a better approach is more than welcomed. This is the first time I actually try to parse full syntax of a language. Basically what you gave me looks good enough to do what I want, I will also look at the classes themselves, I am surprised how small package AST is. I guess that the beauty of the smalltalk syntax. :) On Fri, Jul 25, 2014 at 10:51 PM, Thierry Goubier <thierry.goubier(a)gmail.com > wrote: > Le 25/07/2014 21:42, kilon alios a Ã©crit : > > ok we are getting somewhere, the problem is that if I do > > (SomeClass compiledMethodAt: #nameOfMethod it will look only in the > instance side for method, how I look also for class methods ?

About deprecating UpdatingMenuMorph

by stepharo

Hi guys I would like to simplify the Menu logic and I would like to remove the UpdatingMenuItemMorph. So far it is only use in Spec with autoRefresh. I really think that if we want to give a chance to Morphic and its future incarnation we should rationalize what we have. Stef

Thanks. But when you start to use the ast, you'd better have a look into the RBParser / RBAST stuff, no? Thierry
