Re: [Pharo-project] OSProcess under Pharo

by Bill Schwab

Bryce, Thanks for your reply. Actually, I mentioned FFI etc. because that appeared to be a way to get what OSProcess wanted in terms of dependencies; using Universes should handle that part for me. FFI would be of interest on its own, but appears to make people nervous. Is that for good reason? Put another way, if I want to make some calls into a dll/so, do I really need to mess around with creating/compiling/distributing a plugin? It seems like a lot of overhead, especially since Dolphin does such a nice job based on a mechanism very similar (in apperance at least) to FFI. That said, I am interested in candid opinions; maybe things really are different in Squeak/Pharo. Thanks! Bill Wilhelm K.

I load OSProcess and FFI from universes, it works loading into a recent pharo-dev image. There's an issue with CommandShell as it subclasses off some MVC classes, I think it's safe to ignore. I'd load VMMaker from SqueakSource directly, but it depends on what you want to do. I've merged the FreeType changes into the Exupery VM's and will add closure support in the next few days. Loading Exupery-dev from the universes will load all the packages you listed. (Though, there's an incompatibility between Exupery and the stricter instance variable checks in Pharo, will be fixed in the next release.)

Any down arrow means that at least one subclass is implementing a method with the same name. Orange down arrow means just that, a cyan down arrow additionally means that the method you are looking at is abstract, but subclasses do implement the method. David

Hi keith Since I'm more in doing than talking.... I read the code of Installer I reformatted the code and publish it. I did not change anything so far.

[Pharo-project] SIF working - needs a small fix

by Bill Schwab

Hello, I would like to tell you all the incredible things I did to get SIF going - truth is, it loaded and just worked. The only gripe I have is that the Pharo browsers are displaying a large number of LF or other non-printable characters as boxes in the Pharo browsers. I have seen Squeak do this many times, and either just ignored it or deleted them, as my need to view the code and tolerance level allowed. It will get old with the amount of code I plan to move. How would YOU fix this? Is it a SIF problem (dumping out things it should not from Dolphin), a SIF problem (not supressing characters as they are loaded in Pharo), or something missing in the browsers that is expected to be fixed in Pharo?

Before doing something I might regret, I wanted to check with you about installing OSProcess, VMMaker(?), FFI, etc. Do you have anything to say "try it and report any problems?" Bill Wilhelm K.

Re: [Pharo-project] Fwd: Strange bug

by StÃ©phane Ducasse

Yes I can believe you. The mechanism in fact hijack the organisation field to put the method dict and the method dict field is nilled. Then the idea is that the virtual machine when it gets nil in the method dictionary will not crash but it will restore the method dict this way you can see how much classes a certain function uses. Now what we saw with mathieu is that when a browser is open all the classes are used: it means that all the methoddict are accessed somehow and we wanted to know why this was like that but we could not find it. And we found this bug that fucked up the image of mathieu.

I have subclass implementing it (when the arrow is orange). Am I correct? I'm confused with a down up inconsistency.

[Pharo-project] Senders and implementors list with package

by StÃ©phane Ducasse

Hi david in the latest version of pharo when you browse the senders of a message you get the usual list but the items show in addition the package in the item after the category (which is useless to my eye). Could you add that to OB senders and implementors? Stef
