Re: [Compiler] Variables in DoIts

Wow, I think thatâs super cool!! And a worthy direction to explore.

Re: [Compiler] Variables in DoIts

by Marcus Denker

The next steo of this has been merged: we now evaluate DoIt methods in a way that we do not - need a method header - need to transfrom the AST for adding a return See the (now merged) PR of Denis here: https://github.com/pharo-project/pharo/pull/11463 This means that DoiT evaluation does not rely on the parse tree rewriter and does not need to be pretty-printed anymore. (which dies speed up #evaluate:, too). The screenshot shows code from a Playground, setting a playground binding a to 1, then a temp b to 2, then it enters the debugger due to the #halt. In the debugger we can read a and b, and we can eval âb haltâ to see that what used to be a âDoItIn:â accessing b via the context now looks just like the code that we executed from the first debugger: > On 24 Jun 2022, at 13:51, Marcus Denker <marcus.denker(a)inria.fr> wrote: > > Hi, > > We finally merged a PR form Denis (Sorry for taking too longâ¦) that enables the use of DoitVariable in DoItIn: methods: > > > <Dionisiydk_2022-Jun-23.jpeg> > Denis: #pharo has finally transparent variables in the debugger doIts.

Iâd be interested to be on the committee. Any date is okay, since Iâm local to Toronto. It would be good to have a real âCamp Smalltalkâ where we could have a time and place to code together. There hasnât been a big Smalltalk event in Toronto since the 1990âs, IIRC. Itâd be great if Richard has actually sparked a âSmalltalk Renaissanceâ (a least in Toronto).

Yes, Iâm interested but would prefer the second half of June (our school is on the quarter system) and would prefer weekdays rather than weekends.
