Re: [Pharo-project] Open a view to compare two metods

by Benjamin

I guess you can do something like (DiffMorph from: (MyClass>>#myFirstMethod) sourceCode to: (MyClass>>#mySecondMethod) sourceCode) openInWindow (I tried it in 2.0). Otherwise, I do no think that such a tool exists in 1.4 (in 2.0, you can do it with Nautilus).

[Pharo-project] Open a view to compare two metods

by Dario Trussardi

Hi, i work with Pharo 1.4. I have a class with some methods. Now i'm interested to open a view to compare and see the difference relative two methods of a class. I see into method version the Compare to current buttons. It display the change. I can create this view relative to two methods of one class ? Thanks, Dario

this is why we should migrate from SS And check the configurationOf in the metacelloRepository.

What persistence option do we currently have I like to add plain fuel. I store e.g. configurations with it as these change rarely. For reliability I applied a sequence file to it. Meaning I write files with .fl.1, .fl.2, etc. and a file seq containing the last written number extension. The mechanic is to first write the fuel file and then overwrite the seq file with the actual sequence number (if a write fails the seq file isn't changed). Reads are reading first the seq file and then the fuel file. > 2. What persistence is used in your Pharo application today GemStone, MongoTalk (maybe soon it will be voyage, too), Fuel, Sixx.

[Pharo-project] Small mini howto on moving a project to SmalltalkHub

by GÃ¶ran Krampe

Hey! I just moved one of my projects from Squeaksource.com to SmalltalkHub.com and realized others may want to know how to do this: 1. Create new corresponding Project on Smalltalkhub. Using the same name and tags is probably smart. Also, I added a BOLD little remark with a date claiming this is now the PRIMARY repository for Phriak, if people wonder. I also added the following on top of the project on Squeaksource (you can still edit stuff): NOTE: This project has been moved to <a href="http://smalltalkhub.com/#!/~gokr/Phriak">http://smalltalkhub.com/#!/~gokr/Phriak</a>!!! 2. Add contributors (I just looked through my commits to figure out who they all are) by going to "Settings" (or press "Edit info" button) on the Project. World writeable is not available. I also sent an email to my contributors mentioning this move :) 3. Copy over all old snapshots, using code like this (thanks Nicolas, although it should be "fetch" not "pull" and one needs "/main" at end of hub URL): Gofer it squeaksource: 'Phriak'; package: 'Phriak'; package: 'ConfigurationOfPhriak'; fetch. Gofer it url: 'http://smalltalkhub.com/mc/gokr/Phriak/main' username: 'gokr' password: 'secret'; package: 'Phriak'; package: 'ConfigurationOfPhriak'; push. ...and that's it I think! regards, GÃ¶ran

Fuel is well known, very good serialization library basically.

The auto faulting is done using Ghost proxies (so parts of your domain model are loaded "on demand" when you send messages to them). Oak is not super automagic like Magma - it doesn't do GC for example. But it is quite fast, small codebase and since it has a very simple model you can use other aspects of Riak through Phriak on the side. > > Oak is live and kicking and we are improving it by the day.
