Re: [Pharo-project] Something is messing with the method's timestamps

Re: [Pharo-project] Polymorph layout: images in a column

by Schwab,Wilhelm K

Gary, You're good :) That might be exactly what I need. I just need to figure out how to make it optional. My MVP framework is reducing to presenters being factories for morph/model pairs, and I am pretty much resigning to creating rows and columns using your Polymorph methods. It is different from Dolphin's approach, but seeing what I have been able to do and (even more) looking at what you have produced, it is looking like a good compromise. My big mission is to "say it once." Hopefully my humble framework will enable that while playing nicely with Polymorph. It has various obsolete categories to retain things that I might want to resurrect, but it is becoming usable. Thanks!

[Pharo-project] Something is messing with the method's timestamps

by Ricardo Moran

Hi, I just noticed when I load a project with a metacello configuration, all the method's timestamps are lost. I tried with this configuration: Gofer it > squeaksource: 'MetacelloRepository'; > package: 'ConfigurationOfCTranslator'; > load. > (Smalltalk at: #ConfigurationOfCTranslator) load. If then I load the project by hand (i.e. going through the Monticello browser), the timestamps are back. Also, when I add a new method to a class it gets added without a timestamp, just after I modify it the timestamp is added correctly.
