Load SSO and WebSocket from Metacello Configuration?
by HernÃ¡n Morales Durand Feb. 16, 2016

Feb. 16, 2016

Hello, I want to load SSO and WebSocket packages from ZincHTTPComponents in my Metacello Configurations. Unfortunately there is no ConfigurationOfSSO or ConfigurationOfWebSocket I am aware of. I am loading currently in a #postLoad method this way: #('SSO' 'WebSocket') do: [ :each | #ConfigurationOfZincHTTPComponents asClass project bleedingEdge load: each ]. But a load exception is thrown because I have subclassed some classes from such packages. Can anyone help me by commenting or sending a code snippet of what could be the right solution for such situation? Thanks HernÃ¡n

Bloc Space within a Space
by Sean P. DeNigris Feb. 16, 2016

Feb. 16, 2016

I always wanted to do this in Morphic, but it made too many assumptions about the World's environment e.g. use of globals like ActiveHand and World. I gave it a shot (see below). The new space did appear in the current world, but the rectangle seemed to open in the container world, not in the new world because when I closed the new space via the halo the rectangle remained. For me, it is very important to have a space easily create-able and drivable. This makes real testing possible, prevents another global mess, and makes other /really/ exciting possibilities within reach. Can it be done in Bloc? If not, what would it take? s := BlBlocSpace new. root := s rootElement. root extent: 500 @ 500. root openInWorld; yourself. rect := BlElement exampleRectangle. rect openInWorld: root world. s redraw. root updateDrawing. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Bloc-Space-within-a-Space-tp4877474.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Is there any documentation for the Pharo AST and any ways to affect Pharo syntax ? -- View this message in context: http://forum.world.st/AST-documentation-tp4877909.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Compiling Pharo to C++
by kilon.alios Feb. 16, 2016

Feb. 16, 2016

So doing further research into Unreal , I have reached the conclusion that the best way to integrate Pharo is make a compiler that takes Pharo code and compiles it to C++. I have barely scratch such area when I was playing around with Pharo AST nodes. Any advice / ideas how to accomplish this ? Currently my goal is to start super simple, with compiling small pharo code fragments to C++ code and then much later on even introduce extensions to the pharo language to accommodate for C++ features like templates , pointers (FFI probably already cover this) , static types etc. Obviously if I can keep the pharo syntax intact would be the ideal option. -- View this message in context: http://forum.world.st/Compiling-Pharo-to-C-tp4877775.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

I've had an idea for years which I'm very excited about that requires this functionality, and I've been waiting for a tool powerful and flexible enough to implement it! It looks like Bloc will be that tool and I'm happy to help and wait a bit longer... ----- Cheers, Sean -- View this message in context: http://forum.world.st/Bloc-Space-within-a-Space-tp4877474p4877878.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

That was always a wish of mine in Morphic, however in Bloc, the equivalent is a space, not a Bloc world. A Bloc world only holds the objects on the desktop, not the halos or hand. Pharo Smalltalk Users mailing list wrote > one should be able to script a space, > thus, one should be able to write a test with a local BlocSpace, adding > elements into it and so on But how to drive it? e.g. simulate events Pharo Smalltalk Users mailing list wrote > but your code does not make sense regarding how Bloc is designed > you can have one and only one **active** BlocSpace at a time. I understand from a Pharo perspective that one is only expected to have one *real* space at a time which is receiving hardware events and such, but what prevents us from simulating Spaces?! If there is a SpaceElement, and Elements can be placed in the World, the principle of uniformity encourages that a SpaceElement can be placed there like any other.

Exactly, like the VM simulator! Sign me up! This was the level of uniformity and explorability that I always wished in Morphic ----- Cheers, Sean -- View this message in context: http://forum.world.st/Bloc-Space-within-a-Space-tp4877474p4877733.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Monticello reverse project dependency
by Peter UhnÃ¡k Feb. 15, 2016

Feb. 15, 2016

Hi, I have the following situation: I have ProjectMain, and ProjectPlugin, now normally the Plugin depends on Main, however I would like to load Plugin as part of Main. The problem is that I can't specify to load Plugin after Main has been already fully loaded, if I do something like this BaselineOfMain>>baseline: spec <baseline> spec for: #common do: [ spec baseline: 'Plugin' with: [ spec repository: '...'; loads: #('default' OR 'plugin') ]. spec package: 'Main' with: [ spec requires: #(more stuff) ]; spec group: 'default' with: #('Main'). spec group: 'complete' with: #('default' 'Plugin') ] The BaselineOfPlugin has two groupsâ¦ "default", which loads also "Main", and "plugin", which doesn't. Now the problem is that there is no guaranteed way that Plugin will load after Main (in fact the should happen). If I load the plugin's #default, then Metacello ends up in an endless loop for some reason, and if I load #plugin, then it will load it before the Main which will break it (because Plugin has dependencies on main). So my question is: is it possible to reverse it somehow? Maybe add at the end `spec postLoadDoIt: #postLoadPlugins`, and then in that method manually load the plugins with Metacello/Gofer? Or is there a better way? Thanks, Peter
