Yes we would love to have the same facilities. This is why we worked on Fuel because we would like to have a better deployement (but this is orthogonal to deliver dll). We would love people to work on that. > My password manager PasswordsPro is still in Dolphin and will stay there for > some time yet ... >

Re: [Pharo-users] How not to serve an AngularJs application from Pharo

by stepharo

I'm really interested to see how we could develop amber inside pharo and generate JS/amber code. May be you should look at spec instead of OB.

Re: [Pharo-users] Memoization Question

by Norbert Hartl

Ghost won't be a big help here. Slots would be a good solution but not if it needs to be removable on runtime. So it seems MethodWrappers is your best bet. I'd try create a caching MethodWrapper, mark all the needed methods with a pragma and then install the MethodWrapper on these. Could be a package wide install/uninstall if you need that.

Aspects would solve this but we do not have that. Also I need the mechanism to be removable. So, I read something about MethodWrapper, ghost, slots... Can't one use any of these things to do this memoization cleanly?

Re: [Pharo-users] OSProcess command never ends

by Offray Vladimir Luna CÃ¡rdenas

Hi, Thanks Dave. Your detailed explanation helped me to understand what was going in. The problem was that I don't use /bin/sh as my default shell, so there was no process associated to it (/bin/zsh was the parent of all shell process including launching Pharo). Now I have changed the way I use to launch pharo from my zsh shell. It goes something like this: /bin/sh ~/Programas/Pharo/pharo-ui ~/Programas/Moose/5.0/moose-5.0.image Now is working well. The only thing is that the last process is always running, so I put an 'echo "something"' as the last argument of the OSProcess command: to get all previous commands working instead of making all but the last one (which waits forever and exec doesn't work).

Memoization Question

by phil＠highoctane.be

How can I do memoization in Pharo? I mean, a generic mechanism that will help me wrap the caching around the method invocations / messages. I have expensive calls that do not have to refresh their results as often as they are called. TIA Phil

Re: [Pharo-users] Zoomable & Infinitely scrollable PasteupMorph

by kilon alios

Yes I understand this already, but I assume you mean something that already works with morphs which something I did not realise when I first replied.Dont know if Roassal offers something similar for mophs, but since none said so already I will assume it does not. In any case moving Morphic to Athens will need quite an effort since there are so many morphs to port. I dont think your request is unreasonable. On Mon, Nov 3, 2014 at 4:29 AM, Sean P.
