How to deploy headless app without changes and source files?
by Andreas Sunardi Nov. 19, 2017

Nov. 19, 2017

I found this StackOverflow question: https://stackoverflow.com/questions/14737695/is-it-possible-to-deploy-a-pha… and this older forum thread: https://www.mail-archive.com/pharo-project@lists.gforge.inria.fr/msg21170.h… I'm using Pharo5.0 and neither of these options is available anymore. What is the new way to do this? -- Andreas Sunardi

X11 options on Ubuntu VM / Athens rendering problems
by J.F. Rick Nov. 18, 2017

Nov. 18, 2017

I'm running a fullscreen Pharo application on Ubuntu and I've noticed that Athens rendering gets way worse (maybe 10 updates per second) when I switch to fullscreen mode from inside Pharo. Ideally, I'd love for that to be fixed. In lieu of that, it would be cool if I could just maximize Pharo to the size of the screen to achieve good performance. Two things stop that: the Unity application bar and the title-bar. For the former, I can configure Unity to hide it. I noticed a '-notitle' X11 option when I execute pharo -help. I've tried using these X11 options and neither -notitle or -fullscreen seem to have any effect. Here's the command I run: ./bin/pharo --encoding utf8 -vm-display-X11 -fullscreen PATH_TO_IMAGE & Pharo starts fine but neither option seems to have any effect. I've also tried this in GNOME, thinking that Unity was the problem. Again, no effect. Any suggestions? Jeff

Teapot and Websockets
by Georges Nov. 18, 2017

Nov. 18, 2017

Hello, Is it somehow possible to have a Teapot server running within there a WebsocketHandler (for instance ZnWebSocketChatroomHandler). Something like: Teapot on WS: '/ws-chatroom' -> [: aWebSocket | self registerWebSocket: aWebSocket ]; start. Or is this totally wrong?

by Prof. Andrew P. Black Nov. 17, 2017

Nov. 17, 2017

Is there a way, in SmaCC, or either - writing a grammar production that involves EOF (end of file) - or, writing a scanner action that is executed when EOF is read. Andrew

Network data exchange - Basys and Seamless usage questioning
by CÃ©drick BÃ©ler Nov. 17, 2017

Nov. 17, 2017

Hi all and Denis, Iâve played a bit with Basys and Seamless. Basys is the low level P2P connection framework used by Seamless. First, thanks for such works. Heavily documented and tested. Thatâs super cool. My objective is to have several images running (one representing one app belonging to one or more singular entity realm). Lets say image A1, A2, A3 belongs to Alice. And image B1, B2, â¦ to Bob. They exchange messages conveying information. So the aim of the network layer is for me to keep messages synchronized betweens A(s) and B(s). I have inbox and outbox for that. This is actually quite close to the basys abstractions on LocalPeer and RemotePeer (active and passive). So I played a bit with basys and can declare a network between A1 and B1 for instance. I wonder if I need as much network as possible connection (A1B1 A1B2 â¦ but also A1A2, A1A3, A2A3, â¦). Not sure how to declare network with more than 2 nodesâ¦ I can send string message, and eventually binary. I think I may implemented proper message send. Then, there is seamless that is based on basys and that is far more complete. Several transport and message send possibilities, distributed object with proxy remote delegation, etc. I could use seamless but I find it goes too far for my purpose (it can actually execute code in the remote image - I donât want that, at least by default). At first I don't want to execute code on the peer, only send message to it and received message form it (some of this message could be code invocation but actually more in a business process manner, meaning I activate an activity, but code run locally). This being said, do you think 1) itâs better to use Basys and subclass BasysNetwork (I used BasisNetworkStub) ? I just send message serialization ? 2) or may I use Seamless straight with restrictions (I wonder if limiting the classes that can be executed would suffice - proxies should only be on the peer inbox and outbox I think) ? 3) or maybe I should do a lighter version of seamless ? If so where should I look at/change ? TIA, CÃ©drick

Using PharoCloud: 500 Internal Server Error (nginx)
by Juraj Kubelka Nov. 17, 2017

Nov. 17, 2017

Hi! I am playing for the first time with PharoCloud. I do the following steps: - download Pharo 6 image - open the image and execute `ZnServer startDefaultOn: 8080` - tests http://localhost:8080 <http://localhost:8080/> (I see Zinc welcome message) - save and quit the image and compress the image and changes - login to PharoCloud using Pharo Association account https://www.pharocloud.com/manager/connect <https://www.pharocloud.com/manager/connect> - upload the ZIP archive with Pharo image and changes using PharoCloud Ephemeric Manager v3.0 web interface - set expose ports to 8080 and submit the configuration - activate the image, it asks me to login again (and I login with Pharo Association account) - the image is active (green circle) - click on its hostname and I see 500 Internal Server Error (nginx) instead of the welcome message Is it suppose to work? Do I miss something? Thanks, Juraj

Pharo 6.1-64 on Ubuntu 17.10 (Artful Aardvark)
by Richard A. O'Keefe Nov. 17, 2017

Nov. 17, 2017

The "Welcome to Pharo6.1" window has a navbar on the left starting with "Welcome to Pharo 6.1" and ending with "Getting Help". 3rd to last is "Using Eternal Packages", which should read "External".

Nov. 17, 2017

Hi all, I just wanders if there are pharoers, or more generally smalltalkers located in the south west of France ? If yes, Iâd like to meet from time to time to hack some stuffs or just discuss around a beer. Meeting every 2 or 3 months could be nice. The area is quite large (from toulouse to Pau, Biarritz up to Mont-de-Marsan, eventually Bordeaux and also Spain border). I live between Tarbes and Saint-Gaudens. I work in a mechanical engineering school and there, I try to push Pharo and get some students into it (not easy as they are not computer scientists). In Pau UPPA (University), there are computer science students, but I donât know them really. Cheers, CÃ©drick

FFI 64 bit libClang issue on Sierra.
by Todd Blanchard Nov. 17, 2017

Nov. 17, 2017

I've got it loaded, have fixed up the library path and fixed the test for version (built in lib returns very different version string). I have many tests green. However, as before, tests involving CXSourceRange that return CXSourceLocations return all zero'd data. The CXSourceRange struct looks sane. The calls to CXSourceLocation clang_getRangeStart(CXSourceRange range); and its twin RangeEnd result in zero'd structs. Any idea on where I can look to try to figure out where this is going wrong? I have compiled little C programs and verified that both struct sizes agree in FFI and native code (24 bytes each). Not sure what to try next. -Todd Blanchard
