Re: [Pharo-users] Custom DND Drop Action?

by Sean P. DeNigris

Never mind. I found #handleDropMorph:, which I missed the first time because it is not in the dropping/grabbing protocol, but is instead in events-processing. Maybe it should be moved? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Custom-DND-Drop-Action-tp4803667p4803668.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Custom DND Drop Action?

by Sean P. DeNigris

How do I accept a dropped Morph, but do something other than the default add-as-submorph? I want to drop a Morph into a TextMorph and have it be automatically converted into a TextAnchor, but instead it becomes a submorph and takes over all available space so the contents of the TextMorph can not be changed. Thanks. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Custom-DND-Drop-Action-tp4803667.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Using SmaCC to transform AST?

by Thierry Goubier

Hi Jean-Christophe, Yes, SmaCC has the infrastructure for doing that, in text form (match an ast subtree, produce a string) and linked to SmaCC produced ASTs (I believe by using a GLR parser to generate multiple matches on an input pattern). Using text is a deliberate design decision [1], as far as I know, and I can understand why ;) But under some conditions, you can easily move from text replacement to AST subtrees injection; ask me for more details. For a system that transform ASTs, you want want to look at DMS [2]. Just significantly more expensive. Another idea would be a derivative of the RB engine you have in Pharo (after all, RB is from the same guys as SmaCC). At the moment, the rewritting part of SmaCC is not that tested (or not working, for the master/slave client/serveur rewritting engine part), so I'd be really interested to have some feedback if you decide to use it.

Using SmaCC to transform AST?

by Jean-Christophe Bach

Hi, We are trying to transform programs (from Delphi to Java). We already have source and target ASTs and we would like to write the transformation itself. We are wondering if we could use SmaCC to do that but we are not able to figure out how. The documentation is not clear on the fact that it is possible or not to use any AST as input. Does anyone know if it is possible? Then, in the tutorial, the example seems to be a string-based transformation while we would like to transform ASTs. Are we wrong? What have we missed? In Python tests, there are ASTs but we did not find any transformation. Has someone a clear and concise example to help us to start? Thank you in advance, Jean-Christophe

Re: [Pharo-users] [Pharo-dev] spotter preview

by Tudor Girba

Hi, Hmm. I cannot reproduce your problem. I do this: - Shift+Enter - Spotter is opened without preview - Cmd+P - preview is opened - Esc - Shift+Enter - Spotter is opened with preview - Cmd+P - preview is closed - Shift+Enter - Spotter is opened without preview Does this not work for you in this way?
