[Pharo-project] Fuel or image segments (project files)

Since I was constrained to use an oldish 3.9 image, I had to find what worked through some experiments. What I use now (maybe that looks ugly these days, but works the way I need): To save the current status of the application: "---------------------------------------------------------------------------------------------------------------------" Project current storeOnServerInnards. "---------------------------------------------------------------------------------------------------------------------" This bypasses the dialog that asks for saved project file name and location, and just saves a new version of project file in the directory of the image file, and in the Squeaklets directory underneath. Versioning is important for me because if something goes wrong during the saving of a project I can simply load a previous version manually. To load the last saved version of the project with given name: "---------------------------------------------------------------------------------------------------------------------" loadProject: aString "load a project from a file whose name is like XXX.nnn.pr from the default directory where XXX are letters, and nnn are numbers. A project with the highest version will be loaded" | files dir | dir := FileDirectory default. files := (dir fileNames select: [ :fn | | prts | prts := fn findBetweenSubStrs: '.'. ((prts size = 3) and: [(prts at: 1) = aString & (prts at: 3) = 'pr'] ). ]) asOrderedCollection sort: [ :e1 :e2 | | en1 en2 | en1 := (e1 findBetweenSubStrs: '.') at: 2. en2 := (e2 findBetweenSubStrs: '.') at: 2. (en1 asInteger) > (en2 asInteger). ]. ^files ifNotEmpty: [ ProjectLoading openFromDirectory: dir andFileName: (files at: 1). Smalltalk garbageCollect. ] ifEmpty: [ nil ]. "---------------------------------------------------------------------------------------------------------------------" so that's ProjectLoading openFromDirectory:andFileName: I am not saving any code, only data. But if Fuel provided a way to overlay application-specific code over the generic image, this way of binary deployment would be very convenient. Especially given the tablet's CPU is very slow, loading large mcz's from Monticello repos and compiling them may take terrible time. Thanks. PS Saving methods did not work in the old Squeak image anyway... Even on a PC. -- Dimitry Golubovsky Anywhere on the Web

[Pharo-project] anyone have a more up-to-date MethodWrappers for Squeak than MethodWrappers3.9-pmm.10?
by Eliot Miranda Sept. 16, 2011

Sept. 16, 2011

Hi All, the most up-to-date MethodWrappers I can find is for Squeak 3.9, pre-closures. Anyone have anything compatible with Squeak 4.1/4.2/Pharo 1.1/1.2/1.3? -- best, Eliot

[Pharo-project] Minimal buildable Pharo image with GUI?
by Dimitry Golubovsky Sept. 16, 2011

Sept. 16, 2011

Hi, I feel a need in as small as possible Pharo image (ideally script-buildable from e. g. PharoKernel) to use on Android as a setup/administration tool (I might just bundle it with CogDroid). I need basic Morphic (maybe even w/o PolyMorph) and network, perhaps that's it. Has anybody done anything similar? Any ideas? Thanks. -- Dimitry Golubovsky Anywhere on the Web

Hi this is early (at least to me) and I was asking myself a probably stupid question. But I would like to get your smart answers :) does a smalltalk like language really need explicit return in []? Q1 When are they absolutely required? Q2 What replacing mechanisms would be needed? Q3 What would we gain from an implementation stand point? It seems that in resilience lars removed them and more. Stef for Q1 I see foo x isZero ifTrue: [^ 33]. self continue
