Re: [Pharo-users] Roasssal not working on Windows with Pharo 6.1

by Jan BlizniÄenko

I recommend replacing your VM by last stable one from http://files.pharo.org/vm/pharo-spur32/win/stable-20170827.zip and if it does not help, replacing the image by current one from http://files.pharo.org/image/60/60510.zip You probably use older image or VM that either contained some kind of bug that has been already fixed in current version, or something has been changed, Roassal adapted to it, but your older image or VM does not contain that change to which Roassal is adapted now.

Igor I will share the dropbox for you. What would be great is to port the code of clement to Pharo 6.1 or even 70 to check SDL20 Esteban was integrating some of the code of ronie.

This is not all we will do but it is a step making it hard for people who do not know Pharo to access the code. There is no solution that would protect us at 100%, so we want a list of solutions fast to implement and covering a large part of the way to access to the code. -- Cyril Ferlicot https://ferlicot.fr http://www.synectique.eu 2 rue Jacques PrÃ©vert 01, 59650 Villeneuve d'ascq France

Re: [Pharo-users] How to include DeployUtils in a Configuration?

by Thierry Goubier

Hi HernÃ¡n, I think what is happening is you're not including completely the DeployUtils baseline. You need to write something like: spec baseline: 'DeployUtils' with: [ spec repository: 'github://fstephany/DeployUtils/repository']; import: 'DeployUtils'. And have one of the packages (or groups?) of DeployUtils listed as dependency of one of your packages.

Re: [Pharo-users] How to find if a method is being executed in a given process

by Stephane Ducasse

Ah ok.... So you should look at what Pablo did because he is handling this case for code update, the idea is that he will put on the stack a kind of notifier so that you get aware when the m is not on the stack anymore.
