Pharo private develoment

by Esteban A. Maringolo

Pharo as a community has support to use its CI server, among other goodies such as SmalltalkHub. But what if your code is not public and you want to have a central repository and continuous builds? Has anybody ever wrote a guide to develop with Pharo in the context of private development? So far I managed to work with a file based repo and a set of workspaces to create a new working image or to prepare it for deployment. But I want to automate it as much as I can. Regards! Esteban A. Maringolo

Re: [Pharo-users] Fwd: Re: Pharo on Android - is it available?

by PBK Research

Hilaire (and Dmitry) Many thanks for your efforts on my behalf. I have looked at the CogDroid page, but was discouraged by the prominent warning that "This project is currently disabled." I am not an expert in combining VM files and images; if it involves anything more complicated than downloading a one-click image, it is beyond my ability. I think the comments on the SqueakVM-tablet site are unduly optimistic. For the time being I shall follow up the helpful comments from kilon alios and others that Amber Smalltalk may be the way to go.

The source repo is at https://gitorious.org/cogvm/dmg-blessed/ and I haven't done any commits to it recently (the latest was at Thursday October 04 2012). So images at Inria should be fine to start with although build from sources is always preferred. It's worh mentionig that Pharo 1.x may be needed to perform the build, and given that Pharo downloading methods have changed since the last time I was working on this project some extra effort may be needed. Also, if serious development is planned, platform codes in the said gitorious repo need to be merged with the current platform codes in other repos (which?), and the whole build procedure needs more attention. Also worth mentioning that only features of Android up to 2.x are used in this build. I have no idea whether recent NDK is compatible, so if the older versions are no longer available, some more effort may be needed to bring this all up to date. Hope this helps. Happy New Year!

Re: [Pharo-users] Spotlight Demo

by Tudor Girba

I certainly do recommend it. I am using it since 3 months in production, and for my purposes (mainly using Moose for various analyses), it works perfectly. But, even if you would get problems, leaving on the very edge is more productive (but more counter-intuitive) when the community is smaller. Just look at Pharo 2.0. It takes longer to get fixes integrated, and if you depend on them, your life will be harder. On the latest Pharo, you might get some problems at first, but I suspect you can find those problems quite fast and the reaction you would get will more than payoff. And yet another reason is this: if you have serious interests in Pharo, you will sooner or later end up wanting to influence one part or another (for example, extend Collection with flatCollect: :)). In this case, working on the latest version puts you in a better position to influence Pharo in the direction you want it to go. As I said, it is less obvious, but I think in our community, it makes much better sense to live closer to the edge. Cheers, Doru On Wed, Jan 1, 2014 at 12:30 PM, Sean P.

Re: [Pharo-users] Pharo on Android - is it available?

by Hilaire Fernandes

Hi Peter, Within Dr.Geo, Dmitry Golubovsky (in copy) helped me a lot for the Android VM with tuning it and writing the necessary wrapper to the OS. (For example to access the virtual keyboard, network). The Android and iOS VM share some points as the need for an ARM's JIT and small improvement over the Bitblt. Tim wrote Bitblt improvements for the Raspberry PI to make Scratch smoother on this device (Check the VM mailing list at http://forum.world.st) Esteban integrated those ones in the iOS VM. If you check the DrGeo' Smalltalkhub repository, you will see a DrGeoTheme package for tablet. It improves the usability. If you know you want your app on tablet, you can from the start make the right design decisions. As I am concerned, I am working on an application for math learning, and making good design decision help if you know it should be tablet friendly from the beginning. Good work!

Re: [Pharo-users] Zinc as a proxy ?

by itlists＠schrievkrom.de

The main idea was: -> Use Pharo as a headless server -> Pharo serves files for a local user (one person application) -> GUI is written in Sencha (js framework) -> Pharo offers additonal (platform) REST-API's for this application and is able to proxy requests for external services (to get ONE-source targets for browser apps) -> now put all stuff together via an installer and deliver this to customers -> GUI is done via alredy installed browser. The main concept has already be done by me via VASmalltalk (and jQuery apps) - under Linux and windows - and it worked. (As an platform REST-API I created a service for ZeroMQ for service detection and IPC communication). Now I want to switch to Pharo and Zinc (no need for Seaside any more) - and be able to offer solutions for Mac, Linux and Windows. That's were I would like to go ... Thanks for your answer ...

Hi Marten, On 31 Dec 2013, at 13:19, itlists(a)schrievkrom.de wrote: > Can a Zinc http-server be used as a local proxy ? Had anyone done this ? > > > Marten Feldtmann It is not a part of Zinc and I havenât tried it yet, but yes it can be done. Thanks for asking, it is an interesting use case ! A transparant, forwarding HTTP proxy is a server that accepts HTTP requests to be proxied. Since in HTTP 1.1 a request is self-describing with the required host header and independent of the server that receives it, all the server has to do is execute the request itself, take the response and use that as its own request handling response. With Zinc HTTP Components being an framework implementing both client and server functionality, we can express this behaviour very elegantly: (ZnServer defaultOn: 8090) logToTranscript; debugMode: true; onRequestRespond: [ :request | ZnClient new request: request; execute; response ]; start. Configure one of your browsers to use localhost:8090 as HTTP or web proxy and this should work. Now, you will notice some problems. There is a bug with gzip compressed responses. And since Zinc fully parses and interpretes requests and responses into an object mode, some issues can come up. Some of those might be bugs, I still have to investigate. Like I said: this is a very interesting use case that will help in further debugging Zinc. Of course, there is much more to HTTP proxies than this, but basically this is it.
