Hi Actually I am not using a specifc tool to generate feature models. For the moment, I am using XML Files to express features because tools like SPLOT use such format so it would be easy to export it into Moose. It would be nice to have the Frascati feature model file, just to test some new metrics and visualisations and better understand the code :) Abdelghani Â DeÂ : Alexandre Bergel <alexandre.bergel(a)me.com> ÃÂ : abdelghani ALIDRA <alidrandco(a)yahoo.fr> EnvoyÃ© le : Mercredi 24 juin 2015 17h03 ObjetÂ : Re: [Pharo-users] Moose Hi!

Re: [Pharo-users] RESTful API with Pharo with Gemstones

by itlists＠schrievkrom.de

We go a very similiar way as Sebastian - but with our company need NOT to build a Smalltalk-only system, but also offer support for several other developers/languages. We use * Zinc REST * Gemstone 3.2.6 We generate code to have: * Swagger-UI and Swagger-Core support (currently 1.2) Earlier the swagger stuff was also handled by Gemstone, but now we create Gemstone-Code to write the Swagger-specs into the server filesystem. Practically the swagger-core support has been working with C# (we had to correct/change the template for source code generation). We see now the need to go to Swagger 2.0, to stay near the development master stream. The whole system is working very stable - the only problem I have is a 10 MB limit on the Gemstone socket system - here the Zinc HTTP System subsystem must be changed to get rid of this problem.

Re: [Pharo-users] RESTful API with Pharo with Gemstones

by Sebastian Heidbrink

Hi Sergio, Zinc-REST is part of the Zinc repository and a fork for Gemstone can be found here: https://github.com/GsDevKit/zinc/tree/gs_master/repository/Zinc-REST.package Most part is to implement the code that generates the Swagger specification for your ZnRESTCall subclasses. But it is no vodoo. It becomes more complexe if you would actually like to use the swagger specification on the server site to do request data validation and error handling,.... I currently use Swagger only for documentation purposes. Amber limitations? Not really. It took me some time to figure out how to configure my servers to cope with CORS for the Swagger-UI and my current jsonwebtocken security mechanism is not supported by the SwaggerUI and I had to allow insecure access for the Swagger UI to the Gemstone server. The Amber Swagger-JS integration works quite nicely. I did not publish the code on Github because the integration is so tiny. I can send it to you if you like. Or no,... let me prepare a demo based on the Swagger petshop demo and I will put it online. Might take a day or two until I find some time.

You can build a simple REST service on top of the Zinc HTTP server quite easily and quickly, there is even an example in the EnterprisePharo book The book is a work in progress but you can get this text here: https://ci.inria.fr/pharo-contribution/view/Books/job/EnterprisePharoBook/l… (see Scripting a REST Web Service with Zinc) > On Jun 23, 2015, at 15:40, sergio_101 <sergio.rrd(a)gmail.com> wrote: > > I have been a project coming up that I really onlyneed a restful API on. > > The front end will be first built on a mobile device(iOS )then back on possibly android, with a very stripped down web application. > > i would like to use pharo/gemstones as the database. > > is there a project out there that allows for such restful API development in pharo land?

hey, sebastian.. this looks great! this looks like what i am after.. did you run into any problems or limitations using Amber as a front end? I have not tried Amber yet, so this might be the right time to give it a shot.. where did you find zinc-rest? a quick search turns up references to it.. should i be able to just install it via my image? andrew - i thought about using the seaside rest add on, but seaside seems to be alot of overhead just to run a rest server.. mariano - i am thinking about using api token..

Just curious. How do you implement authorization/authentication? Is there OAuth(2) support? Or you just use api token?

I use pure Zinc-REST on the Gemstone side and the REST API is described in Swagger-Spec from within Gmestone. Clients are VBA, Amber and Pharo and they utilize the Swagger API spec to access the server. Works pretty well and is much more preformant than the intial Pharo MongoDB backend I initially used. Have a look into http://smalltalkhub.com/#!/~HeSe/Swagger-Spec There you can find most of the needed Swagger implementation some minor details like type constants are missing. Once your Gemstoneserver knows how to host his Swagger-Spec you can host it via https://github.com/swagger-api/swagger-ui This saves a lot of explaning time to client developers. Sebastian
