Deployment pharo with multiple instances and voyage
by Alejandro Infante Jan. 26, 2017

Jan. 26, 2017

Hi! Iâm close to deploy a web service using Pharo with Voyage and MongoDB. I have been playing with it and everything works ok with a single Pharo image. Couple of days ago I started questioning myself about how voyage behaves when you have multiple pharo images using the same mongo database (horizontal scaling). I want to know how the cache of voyage behaves in a scenario with object updates. Example: ââââââââââââââ Imagine I have two images A and B. - Image A query for object o and voyage put it in the cache. - Image B query for object o and voyage put it in the cache. - Image A updates object o and push it into the database calling #save. - Image B query for object o that should be already in the cache. In this case, does Image B see the changes performed by image A? ââââââââââââââ All ideas are welcome :) Thanks and cheers! Alejandro

Code loading/unloading order
by webwarrior Jan. 26, 2017

Jan. 26, 2017

It is not documented. What happens when I load a package? Are all classes created first, and then methods are added, or classes are loaded one-by-one with all their methods? What about Slots? Are they added to classes after all classes are loaded? Do they have their methods by that time? What is order of loading of classes? Alphabetical, or using some resolution mechanism, or is it implementation detail? What happens when I unload the package? Is it inverse of loading so order is reversed? -- View this message in context: http://forum.world.st/Code-loading-unloading-order-tp4930611.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

PharoLauncher preSpur images
by Ben Coman Jan. 23, 2017

Jan. 23, 2017

Pre-Spur images were not available in my PharoLauncher. I thought they used to be. Were they removed on purpose? Anyway, for other's reference here is the required hack... Add method... PhLHTTPListingTemplateGroup class >> pharo50preSpur ^ self name: 'Pharo 5.0 (preSpur)' url: ' http://files.pharo.org/image/50-preSpur/' asZnUrl Insert into... PhLTemplateGroupRepository class >> groups .... Groups at: PhLHTTPListingTemplateGroup pharo50preSpur put: true. Evaluate "PhLTemplateGroupRepository resetGroups" cheers -ben

Difficulties updating a file directory
by Offray Vladimir Luna CÃ¡rdenas Jan. 23, 2017

Jan. 23, 2017

Hi, I'm having problems understanding how #chooseDirectory: works. When I run this code: GrafoscopioDocumentation current localPlace: (UIManager default chooseDirectory: 'Path to the documents Folder') from a playground and choose a folder in my home directory, results in localPlace containing a FileReference to '/home/offray/Documents/Grafoscopio', which is what I expect. But if I put a similar code here: """ GrafoscopioDocumentation >> updateDocsPlace self current localPlace: (UIManager default chooseDirectory: 'Path to the documentation folder') """ and choose the same folder, I got a relative FileReference to 'Grafoscopio', instead of the one to the full path, that doesn't point to anything existing in my system. What I'm missing here? Thanks, Offray

DNU on materializing a fueled out exception
by Holger Freyther Jan. 22, 2017

Jan. 22, 2017

Hi, I showed Pharo to a friend and wanted to show the nice feature of fueling out an exception and then using FLMaterializer class>>#materializeFromFileNamed: to load it back and get a debugger up. In Pharo5 I am presented a DNU instead. The DNU is on GTGenericStackDebugger as it doesn't understand the message Fuel is sending. What to fix, Fuel to use the new protocol or GTGenericStackDebugger to honor the old protocol? FueldOutStackDebugAction>>#serializeTestFailureContext: aContext toFileNamed: aFilename | serializer | serializer := FLSerializer newDefault. self encodeDebugInformationOn: serializer. serializer addPostMaterializationAction: [ :materialization | Smalltalk tools debugger openOn: Processor activeProcess context: materialization root label: 'External stack' contents: nil fullView: false ]. So it looks like now it should create a debug session first and then pass it to the debugger? I think loading new fuel in Pharo3.x is still possible so maybe it is best to re-add that protocol? comments? holger

Tools for easy subtext extraction from text
by Peter Uhnak Jan. 22, 2017

Jan. 22, 2017

Hi, what are the tools available from easier text extraction? The input is unstructured text, but I want to extract portion from it. I am not looking for an engineered approach (writing a parser or something), but something that can be done quickly by hand (i.e. interactively). For example I have string str = ' Temperature 0 37C (98F) [0x25] (TMPIN0)' Now I want to extract '0x25' from it and convert it into integer In Ruby it is dead simple: str[/\[(.*)\]/,1].hex # "=> 37" , or .to_i(16) In Pharo I have to break my fingers first: rx := '.*\[0x(.*)\].*' asRegex. rx matches: str. Integer readFrom: (rx subexpression: 2) base: 16 "=>37". * I have to know that to get subexpression I have to match first to manipulate the internal state * I have to store the matcher to access the subexpression * I need to explicitly use some global variable Integer as a conversion utility to convert hex to dec * I have to manually remove the 0x, even though it is a very common way of expressing hex numbers So the question is: do we have a better way to do these things? And as I've mentioned - the use case is interactive coding where you often throw the code away when you are done; so dead easy to write and use. Thanks, Peter
