Re: [Pharo-users] Regarding Raven: DOCap System

by aglynn42＠gmail.com

One thing that occurred to me is that the whenResolved etc. handlers only need to be customized to the degree that you want to interop with Java types that are not self-describing, such as the faked primitives and interfaces. Smalltalk types are uniformly self describing, allowing you to implement a single handler for all types, whereas only certain kinds of Java types are self-describing. If you think about it in terms of RMI, which is not really much different other than the metaphor not taking time and frequency of non-response into account, the promises and futures are much like stubs and skeletons, proxies for the remote message send and resulting method invocations/responses. A Smalltalk to Smalltalk interop such as SST, which is very similar to RMI, only needs one proxy for all objects, which makes abstracting it from the transport (and whether the transport is continuous etc.) much easier. i.e. in RMI you need pools of constant TCP connections, while in SST the transport needenât be a continuous connection, it could be entirely discrete such as http, and only one abstract connection between âspacesâ or ânodesâ is required. If you avoid the nasties in Java and only support interop for self-describing types, you shouldnât need to write so much custom but rote code. If you do need to support non self-describing types, only on those do you need the custom rote code in the handlers. Further if you use only one set of proxies, i.e. one future/promise/handler set, it will be much easier to keep Raven clean and separated from the transport implementation. If you keep in mind that although itâs a useful and powerful metaphor, the notion of futures, promises and the like is only a metaphor for invoking remote methods, which in turn is only a more mentally adhesive manner of describing remote procedure calls, with self-describing objects one handler can invoke the appropriate methods on the object by delegating the responsibility to the object itself.

Hi holger we are planning to work again on Module once we release Pillar 70 and Iceberg v2.0. We did not want to let Pillar die so we had to do something to put it in the rails for the future.

But that's one of the main ideas behind PI https://github.com/hernanmd/pi So tomorrow there could be a Donatello tool and the pi command will be the same for dev and stable.

SDL2SpecialCharacterMapping problem

by alvaro piorno

Hi, Iam having a problem handling some OSKeywordEvents. These events should have character associated. The mapping is resolved by SDL2SpecialCharacterMapping using a dictionary(Mappings), it has the mapping, for example, for left arrow and right arrow. It resolve correctly for "left arrow" with key: 1073741904(Integer) , but it does not found "right arrow" with key: 1073741903(Integer). Both keys are present. Any idea?

Something similar to > "git pull" when you know the repository. Hello! Gofer is the old buggy way to load a project. The current way is to use Metacello. Here is the script: Metacello new smalltalkhubUser: 'ObjectProfile' project: 'Roassal2'; configuration: 'Roassal2'; version: version; load Note that "version" can be: - #stable : It will take the current stable release for your pharo version - #development : It will load the latest version of the packages declared in the current development version (generally the latest baseline) for your pharo version - #bleedingEdge : A symbolic version that specifies the latest mcz files and project versions - A specific version or baseline name - A release name In your case you probably want the bleedingEdge version. But be aware: since it's a bleeding edge version there is no guarantee it will load and work. Metacello new smalltalkhubUser: 'ObjectProfile' project: 'Roassal2'; configuration: 'Roassal2'; version: #bleedingEdge; load For more informations about Metacello you car read this chapter of Deep Into Pharo: http://pharobooks.gforge.inria.fr/PharoByExampleTwo-Eng/latest/Metacello.pdf -- Cyril Ferlicot https://ferlicot.fr

[ANN] MaterialDesignLite for Seaside v1.2.0

by Cyril Ferlicot D.

Hello everyone, Today I released the version v1.2.0 of MaterialDesignLite for Seaside. (https://github.com/DuneSt/MaterialDesignLite) The main changes are: - There is a brand new demo with more examples and documentation. You can find it here: https://mdl.ferlicot.fr - There is a new concepts: The extensions. Extensions are not describe by Material Design but are meant to help developers while building web application. This release contains 3. A way to simplify the use of dialogs, called "root dialog", a resizeable left panel and a resizeable right panel with tabs. - There is a new widget: the progress widget - New brushes to use premade typography and typogaphy styles This release is tagged with v1.2.0 and I also introduced tags v1.2.x and v1.x.x which are moving tags following patch and minor versions. Here is the full changelog of the release: https://github.com/DuneSt/MaterialDesignLite/blob/b5ef0dcbcb9b84aeea774db38… If you have issues, need a new feature or have a comment on the project feel free to open a issue: https://github.com/DuneSt/MaterialDesignLite/issues Have a nice day! -- Cyril Ferlicot https://ferlicot.fr
