[Pharo-project] removing versions from configurations

by Tudor Girba

Hi, The Moose build broke because the 'default' version was removed from ConfigurationOfRPackage. I fixed it now by using #stable, but that is not the issue. I understand the need for cleaning, but we should be aware that removing versions from configurations can have far reaching ripple effects. Cheers, Doru -- www.tudorgirba.com "From an abstract enough point of view, any two things are similar."

Hi guys I'm chasing a strange bug since a couple of hours and what I would love to have is the possibility to change an instance variable into an object that says stop each time you are changed from this flow. Stef

Re: [Pharo-project] new template for class empty comments for OB

by laurent laffont

Why not a "Please comment this class. Look at class XXXX for a good example of comment". Replace XXX with a class you like.

Re: [Pharo-project] new template for class empty comments for OB

by Lukas Renggli

Hi Alexandre, > But this is not incompatible. The IVs may still be listed, > the template can be adjusted for that Yes, this is true and the proposed change takes the IVs into account. The only problem is that I have to scroll to the bottom in 90% of the cases as the variables are a couple of pages below the template text. 90% of the time I am looking for information and then something like the variable types is at least useful, a two page template is only "useful" the few times I actually write a comment.
