Refactoring API and the AST Nodes
by Gisela Decuzzi May 15, 2013

May 15, 2013

I've been thinking about this... because the refactoring api can be a pain to handle (at least for me) in some cases, specially when I'm working with an AST node... because in the node it's all (or almost all) the information needed for the api and I started to ask me... why I'm always opening the node to extract all the strings just to use the Refactorings? I don't like to do that, and I think that time to time we have that problem and ended repeating code... I was thinking in change the refactoring API to accept an AST node, but it's not true that we have the node in the hand all the time we want to use it, and adding more entry points could complex the api. Also if we convert a node in a model for the refactors there are some cases where the information isn't complete in the node, by example to rename a variable you need the new name... and that is not present in the node but needed for the refactor... so is not that simple to make them an inocent model... Then I thought that I can use a new object that takes the node, and creates the refactors needed (similar to NautilusRefactoring using an ast node), but in this model I think that we are doing yet another work around and not a real solution... The other day Guille points me that maybe I should think that the refactoring API is kind of ok... and maybe the nodes could give me the refactors or an almost configured refactor... since they have (almost all) the information. So... I was thinking in this approach, it could be a solution to all the strings handling, and it kind of make sense that the node knows the refactors that apllies and how to construct it with the information needed. A number of ideas... and I would like to discuss about them, maybe here is someone who has the same problem and arrived to a different solution, so I would like to exchange opinions and improve that part that I think we are working around but not solving :(

AsmJit refactoring
by Camillo Bruni May 15, 2013

May 15, 2013

I started to work on a basic ARM model for AsmJit with Damien Pollet and on the fly we continue the refactoring I started last week: - no more PoolDictionaries - no more global registers - reducing the number of class variables - more specific register classes for x86 to avoid nasty bit masking/checking operations on an integer All in all this makes the code much more accessible and you can be sure that changing a register (aka renaming it) is a local cation. What do you think?

success story: NTed
by Norbert Hartl May 15, 2013

May 15, 2013

I think my last post of this message fell into the time the old mailing list dies. So here it is again --- We (@2denker in cooperation with a local university) built a monitoring tool for disaster scenario recovery rehearsals. Several times a year universities, red cross, THW und hospitals are planning a rehearsal together. For this an environment is prepared for a simulated disaster (car accidents, explosions in civil areas, â¦). The local environment is prepared to look real as well as film make-up artist prepare people for injuries (broken legs, open head, â¦). The rehearsal should improve the coordination of several hospitals, firemenâ¦as well as the quickest possible treatment for the injured. One important part of the rehearsal is monitoring of what happens. This is achieved by installing a local position system and using our tool. Every injured person gets a wireless tablet. On the tablet there are UI elements that indicate treatment done to them. Whenever a doctor comes visiting the injured person activates the corresponding UI button. The events are transmitted to a server and are prepared for another analysis software. The tablet enables the HQ to make contact to individual persons or groups. The tablet measures times of needed treatments and instructs the injured to be dead if measurements weren't taken in time. Technically it is done in smalltalk solo. The server is a pharo image. It has - web admin interface with complex forms for managing injuries, injured, groups, etc. For this we used seaside because it is best suited for this job. Forms are done with magritte, magritte-bootstrap. The interface also displays the live incoming events and other data - a static file server that delivers static resources to client tablets - a websocket connector that is used by the clients to connect to the server - a http handler to export data to other analysis tools The client is done with amber smalltalk. It - loads the web page containing amber from the server - connects back to the server - downloads a UI spec for the injured using the tablet to display personalized UI elements - stores events on the tablet in case the injured is offline - measures times to instruct the injured If you have any questions please don't hesitate to ask.

Doubt about RING
by Sebastian Tleye May 15, 2013

May 15, 2013

Hello I am making some modifications in the smalltalk meta-model and i need to replace classes with Ring classes (it is supposed to be possible since they are polymorphic) But i am having a little problem, all the classes know how to answer the message "isObsolete" but Ring classes doesn't, to solve this i have defined the method "isObsolete" in RGBehaviorDefinition but i am not sure which code does it need - if i copy and paste the code from Behavior, then i obtain more "doesNotUnderstand" messages since the code from Behavior>>isObsolete is "self instanceCount = 0" but Ring classes doesn't know how to answer "instanceCount" neither so i suspect this is not the right way to do it. - if i copy the code from Class, then it seems it works, but the result from for example "Array isObsolete" is different of the result from "Array asRingDefinition isObsolete" consequently next messages obtain different results and finally a a "doesNotUnderstand" message again. Am i doing something wrong? Any suggestion?
