Re: [Pharo-users] Iceberg Branching
Hi evan can you describe what you are doing because branching normally works? I know that esteban was working on support to be able load submitted pull requests directly from the branch history. Guillermo and Pablo are making progress on refactoring the core of iceberg. They are arriving to the point where they will start rethinking the UI.

Re: [Pharo-users] Pharo 7 image cannot write changes message on startup
Sanjay I don't know how to identify the VM version - it is the one which was current when I downloaded my current image in July 2017; the .exe has a creation date of 31 May 2017. The point of my comment was that this message does not only come from a conflict of access permissions. In my situation, it arises because the program knows that another program has exclusive write access to the changes file. In your situation, could it be that the program is wrongly coming to the same conclusion? I don't know how Pharo reaches that conclusion; I just thought that it might give a clue to anyone trying to locate the bug. Best wishes Peter Kenny PS.

Thanks ronie. You can ask guille or damien because they gained experience in Travis. S.

[Pharo-users] bloc next experiments
Hi, Happy New Year! We were asked about the roadmap of Bloc several times. It is a perfectly reasonable request given that Bloc is supposed to offer the UI infrastructure for the future of Pharo. However, I was reluctant to provide one because we do not really have a classic roadmap. When we develop Bloc and GT we think in terms of experiments and examples that we want to play with to get us to our goal. Features are a consequence of that. This approach allowed us on multiple occasions to stumble across functional possibilities that we would have not been able to think about before seeing the experiments. It also works the other way around: as we move ahead, we sometime discover modeling problems and we sometimes chase them all the way down. Having said that, we can specify the next examples and experiments that we consider for the next months. Here they are: • Drag and drop that can be customized on an instance basis. In the process, revisit event management and explore making it use Announcements. Use this for the diagramming engine. • Scrollbar for infinite list and the scalable element. • Apply layout once. For example, this would allow us to apply a layout but still be able to drag elements in custom positions without disturbing the others. The first application is in the context of creating diagrams and visualizations. • Apply layout with animation. For example, in Connector, a new example should be spawned and moved to its position through a smooth animation. This will also allow us to play with the concept of animation and MVVM. • Introduce the concept of elevation. This is important for scenes in which we have overlapping elements that are not part of the composition tree. For example, in Connector, the lines connect inner elements inside the text, but they belong to the root. such as a visualization (but not only). For this to work, we need a better element traversing structure. • Experiment with theming. The theming mechanism should be instance specific with per-widget defaults, and the theme values should ideally be injected in the widgets. The CSS implementation from Glenn is one direction. As developing and maintaining themes can be a nightmare in the long run, the theming mechanism to provide debugging tools. • Experiment with delegating animations through the model. Typical MVVM or MVC focus on the behavior of an interaction. We want to get smooth live interfaces and the animation logic should be influence-able by the model. For example, hovering over a button, enlarges the button with extra details about the action. • Basic widgets: list, input box, button, radio button, checkbox, menu, dropdown menu, toggling button, tabs, toolbar. • Table and tree widgets. • Pager interface (similar to the one in the current inspector) with resizable panes.

Re: [Pharo-users] [ANN] Bittrex API
Hi Ben, Thank you for sharing this, looks really cool. I have some issues installing the library. In the "Clone repository" dialog I had to use https://github.com/Traadh/bittrex.git The install procedure did not downloaded the libsodium library. I had to install it from loading Nacl. Any particular difference with Nacl? From the dll in Nacl I can see Bittrex functions are supported but appending a "256" in the function prototype, i.e.: crypto_auth_hmacsha512256_keybytes , maybe you can add the functions to the Nacl repository? http://www.smalltalkhub.com/#!/~tonyg/Crypto-Nacl Or you can use the URL's in ConfigurationOfNacl>>platformLibraryUrl to download the library for each platform, or integrate the download procedure in https://github.com/hernanmd/MetacelloFileDownload Cheers, Hernán 2018-01-13 16:07 GMT-03:00 Ben Coman : > Thanks everyone who advised on Zinc, REST, NeoJSON, HMAC & Libsodium > to help me on my way to implement an interface to the Bittrex bitcoin > exchange.

This was my first time using Libsodium and it was difficult to find examples directly on the HMAC512 function I needed. The sample C code I compiled as a test didn't match the function names exported from Crypto-Nacl so this confounded my trials. It was simple to FFI wrap the one Libsodium function I needed, so thats what I did. The Configuration of Crypto-Nacl downloads a pre-compiled libsodium that exports different symbols to the system libsodium. So IIUC its not a matter of just adding extra Smalltalk methods to the Crypto-Nacl. I don't know enough about Libsodium to understand the difference in function naming and I guess replacing it might break existing users ?? > Or you can use the URL's in ConfigurationOfNacl>>platformLibraryUrl to > download the library for each platform, > or integrate the download procedure in > https://github.com/hernanmd/MetacelloFileDownload good idea. thx for the tip. cheers -ben > > Cheers, > > Hernán > > > > > > > 2018-01-13 16:07 GMT-03:00 Ben Coman : >> Thanks everyone who advised on Zinc, REST, NeoJSON, HMAC & Libsodium >> to help me on my way to implement an interface to the Bittrex bitcoin >> exchange.
