November 2017 - Pharo-users

Re: [Pharo-users] tonel how to

by Juraj Kubelka

Hi Hilaire, I have been playing with it recently. There is my exercise: myClass := MyDemo. myClassName := MyDemo name. snapshot := (MCPackage new name: myClass package name) snapshot. memory := FileSystem memory. writer := TonelWriter on: memory root. writer writeSnapshot: snapshot. "Remove package" myClass package removeFromSystem. "Find myClass file" classDefinition := snapshot definitions detect: [ :e | e isClassDefinition and: [ e className = myClassName ] ]. dir := writer packageDir. fileName := writer fileNameFor: classDefinition. (dir / fileName) contents. "Read and Install definitions" reader := writer class readerClass on: memory root. reader packageDirectory: dir basename. reader loadDefinitions. reader snapshot install. Maybe it is what you are asking for.

The terminal part is actually CommandShell: http://www.squeaksource.com/CommandShell.html At the moment it is tied to OSProcess - which I haven't been able to get working in Pharo for a while, so it may need to be decoupled. Also, don't forget that OSProcess and OSSubprocess can't be loaded at the same time.

The Advent Of Code 2017

by Julien

Hello, Tomorrow starts the Advent Of Code 2017 [1] which consists in 2x programming puzzles per day from the 1st December to the 25th. I created a GitHub repository [2] to collect code snippets around the solutions of the Pharo community (more details in the README). I think these programming puzzles are good to: * Promote Pharo by showing solutions collected in the GitHub repository via your pull requests * Show how cool is the Pharoâs Collection API (last year most of the puzzles required heavy usage of data-structures) * Get a feedback of what could be enhanced in Pharo packages (e.g. if when you solve a puzzle you feel like a message is missing in a class or a message has a bad name which makes finding it difficult, it could be discussed and a case on fog buzz could be opened to solve this during a sprint). To participate, you just need to follow the READMEâs instructions (which basically says that you have to fork the repository, create a directory to store your solutions and create pull requests each time you solved a puzzle). There is a specific channel on the discord [3] that has been created to chat around these puzzles and their solutions. I hope to see a lot of people playing with us at solving these puzzles. :-) Cheers, Julien Links: [1]: http://adventofcode.com <http://adventofcode.com/> [2]: https://github.com/juliendelplanque/AdventOfCode2017WithPharo <https://github.com/juliendelplanque/AdventOfCode2017WithPharo> [3]: https://discord.gg/3QG4YcH <https://discord.gg/3QG4YcH> PS: There is no obligation to solve 2 puzzles per day. I know everyone is busy doing its work but please if you solve these puzzles using Pharo, propose pull requests! :-) --- Julien Delplanque Doctorant Ã lâUniversitÃ© de Lille 1 http://juliendelplanque.be/phd.html Equipe Rmod, Inria BÃ¢timent B 40, avenue Halley 59650 Villeneuve d'Ascq NumÃ©ro de tÃ©lÃ©phone: +333 59 35 86 40

Re: [Pharo-users] I love the launcher!!!!

by Dimitris Chloupis

Unless we talk about a diffident launcher I am not aware of. Pharo launcher is both a GUI last time I checked and loadable inside any image. So technically speaking you donât need neither the GUI nor the command line. You can fully integrate it and automate it with your own project and then publish that project to Package Browser so that downloads and installs from inside the image with a single click. Itâs just regular Pharo code like anything else. On Wed, 29 Nov 2017 at 12:41, Prof. Andrew P.
