Time resolution: which class should I use for millisecond resolution?

by Alex Schenkman

Hi list: Looking at the implementation of Time and DateAndTime it seems to me that the the resolution for this classes is one second. Which class would be best suited for a more precise time stamp? Thank in advance!

Mariano, I can download the mcz's using a web browser, but not from the Pharo Image. This has nothing to do with Pharo, but with the way the web proxy is set up here - it's a policy of the company. The same problem applies to any other application that's not accepted by the Proxy. I don't have the proxy settings due to the company's policy, so I cannot tell if I have a Pharo problem. Let's assume my machine is offline or I have too little bandwidth to download packages, but I can get them on a CD or USB stick, and I'd have the very same situation. BTW: I am using 1.2.1 at the moment Joachim

Why #fetch: cannot work behind a proxy? I didn't understand when he said "I can, however, download packages using the Browser" which browser? firefox or monticello browser? Why you #fetch: cannot go behind proxy if the proxy settings are defined in the image? There was a bug with Pharo 1.3 about this but it was fixed in latest version. Which pharo version are you using? did you try to specify proxy settings? cheers On Wed, Jul 20, 2011 at 7:52 PM, Dale Henrichs <dhenrich(a)vmware.com> wrote: > Joachim, > > You are on the right track with using fetch in an image that is outside the > firewall ... zip up the directory of mcz files and you are off to the races. > > BTW, you don't need an "empty" image if you set ignoreImage to true before > doing the fetch: > > version ignoreImage: true. > > Dale > > > ----- Original Message ----- > | From: "jtuchel" <jtuchel(a)objektfabrik.de> > | To: metacello(a)googlegroups.com > | Cc: "A friendly place where any question about pharo is welcome" < > pharo-users(a)lists.gforge.inria.fr> > | Sent: Wednesday, July 20, 2011 10:44:46 AM > | Subject: [Metacello] Aw: Re: [Pharo-users] Using SqueakSource / Metacello > "offline" > | > | Hi Norbert, > | > | > | thank you for the links. > | > | > | One question remains unanswered: is there a way to determine which > | .mcz files are needed without using #fetch (because fetch doesn't > | work behind the proxy)?

Re: [Pharo-users] Recover lost changes

by StÃ©phane Ducasse

because the changes formats does not support a declarative format (I'm dreaming of and that could be based on ring). So the current implementation fits everything in doit so the tools would have to scan expressions to identify the corresponding actions... I hope that one day we will be able to fix that.

Joachim, You are on the right track with using fetch in an image that is outside the firewall ... zip up the directory of mcz files and you are off to the races. BTW, you don't need an "empty" image if you set ignoreImage to true before doing the fetch: version ignoreImage: true.

Hi Norbert, thank you for the links. One question remains unanswered: is there a way to determine which .mcz files are needed without using #fetch (because fetch doesn't work behind the proxy)? I guess the answer is no, because I have no way of looking into the required Configurations that are unfetched. So I need to use a local directory and try step by step and download the mcz that is currently missing... oh my. Or can I use a fresh image on a machine in another network to fetch all and copy the contents of my package cache onto the target machine??? Joachim

Using SqueakSource / Metacello "offline"

by jtuchel

Hi there, I need to load packages from SqueakSource into an image that sits on a machine behind a proxy that won't let me download from Squeaksource. I can, however, download packages using the Browser. The problem for me is that ConfigurationOfSeaside30, for example, requires a lot of packages to be loaded first. So I know I can donload all the .mcz files from Squeaksource and copy them to my local PackageCache, but I am looking for a way to find out which ones I need. Is manually extracting the info from the ConfigurationOfSeaside30 class the only way to do that? And how would I go about using ConfigurationOfSeaside30 to use my package cache instead of the online repositories? Any ideas?

Re: [Pharo-users] install system fonts on linux

I did as suggested and downloaded latest cog.zip from https://pharo-ic.lille.inria.fr/hudson/job/Cog%20Unix/ I stubbled about the PharoOneClick1.3.app directory structure. This I also retrieved from Hudson build: https://pharo-ic.lille.inria.fr/hudson/view/Pharo/job/Pharo%201.3/lastSucce…. I'm assuming this is cog based. But how do I tell which VM it is as I see the executable in all one-click download scripts such as PharoOneClick1.3.sh referencing squeak or squeakvm, yet the cog.zip file names the executable 'CogVM'?? So I see under Contents/Linux a few .so files that are also in the cog.zip I download. I see that libFT2Plugin.so is in cog.zip but not in PharoOneClick1.3.app/Contents/Linux. So I try copying this over in the hopes that the FT in the file name alludes to FreeType. But no luck. Any more ideas? Some pointers on docs or discussion thread on how plugins work, how to tell which vm is in use, why the FreeType plugin is no longer included in the one-click builds, etc may be useful. thanks, Jon On 07/19/2011 02:30 PM, Igor Stasenko wrote: > On 19 July 2011 18:26, Jon Hancock<jhancock(a)shellshadow.com> wrote: >> In pharo 1.1, in the settings manager, I can "Update fonts from system" and >> have access to all/most ubuntu fonts.
