The Mac vm does it (haven't checked the unix vm, it might too), so if you're able to use that, you can swap out the InputEventPollingFetcher with InputEventFetcher to test how it works. Searching the list should give an example of how to do it properly, transfering existing handlers etc. With that, you should also be able to rewrite the polling Morphic loop to redraw as response to input handling that causes display invalidation, rather than process the available events as part of each draw step.

There are two classes for input event handling in Pharo 1.1: InputEventFetcher and InputEventPollingFetcher. You should be safe to use InputEventFetcher (which doesn't poll for events) on non-windows VMs, but the default is InputEventPollingFetcher. Levente > > tnx, regards > > Guido Stepken > > >

[Pharo-project] Net::Telnet equivalent

by Elliot Finley

Hello, In the past when I've wanted to automate some telnet interaction (provisioning devices from database) I've used Perl and its Net::Telnet module or Ruby and its Net::Telnet module. Is there an equivalent for Pharo? Thanks, Elliot

How is it compared to Mocketry (http://www.squeaksource.com/Mocketry.html)? SMock? BTW, isn't TDD without mocks a bit incomplete?

Create a squeakvm directory somewhere on your server. Download the coglinux.tgz file from the link above, to the squeakvm directory. Un-tar and un-gzip it using: tar -ztvf coglinux.tgz Create a shell script to start your image. The shell script should contain something like (adjust the directory to be where you created your squeakvm directory): ========== #!/bin/bash # vm configuration if [ `uname` = "Linux" ] then PHARO_VM="/home/yanni/apps/squeakvm/coglinux/bin/squeak" PHARO_PARAM="-mmap 100m -vm-sound-null -vm-display-X11 -headless" elif [ `uname` = "Darwin" ] then PHARO_VM="/Users/yanni/apps/squeakvm/Cog.app/Contents/MacOS/Croquet" PHARO_PARAM="-headless" else echo "Unsupported OS: `uname`" exit 1 fi # start the vm "$PHARO_VM" $PHARO_PARAM "$IMAGE" "$SCRIPT" ==========

[Pharo-project] installing a cog image to deploy pier

by sergio_101

i have my pier site ready to deploy on my server. unfortunately, i don't have a cog vm installed on my server.. it's just an old squeak vm i had from the past.. i know i can either use the vm that came with my one click image, or i can use one from here: http://www.mirandabanda.org/files/Cog/VM/ but i am not sure how to install it. i have tried a few different things that i thought made sense, but they didn't work.. anyone have any ideas? thanks! -- ---- peace, sergio photographer, journalist, visionary http://www.CodingForHire.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

Re: [Pharo-project] New macintosh vm builder & maintainer: Esteban Lorenzano

by Esteban Lorenzano

Hi, Thank you all for all your best wishes... I know, John work will be really hard to match, but he wants to pass the responsibility, and I accepted because he promise to guide me for awhile, until I can build the mac vm's... Of course, I have A LOT of things to learn, before been a good builder, but I'll do my best, so, please, be kind... it will take time, until the role is fullfilled in a satisfactory way :) Now, for the coming work, I thought on what would be the first steps... these are my ideas: 1) Create a hudson configuration for the vms, so it can be built automatically. Of course, there are two problems here: a) we need a good test batery, and the vm has not. To solve this, I think the pharo tests will ne a good "starting vm suite": If the tests succed, we can hope the vm "more or less" works. b) we need a mac hudson server. Maybe pharo guys can help here, but I dunno... 1.1) Infraestructure: we need a place were publish new built vms (John's place does not have sense any more)... do you know a place. I suppose squeakvm.org is a good place, but maybe not. Any idea? 2) 4.x series are obsolete, I will focus my work on keep up-to-date 5.x series. Merge with cog is very important here :) Also, I want to work with Eliot on his vmmaker code generation changes, but this will take more time as the code generation insights are triky. 3) Keep the vm working with new changes introduced by apple. Next year will be Lion, and before that, the new app. store... So, I think I have a lot of work to begin... please let me know if there are important things I'm missing. NOTE: As I'm learning, please, when you commit something in VMMaker who needs a special mac treatment, make a comment so I can know it... otherwise the change can be lost in the limbo... And, finally, I want to say we are all going to miss you John, and I more than anybody! Cheers, Esteban pd: btw... I will need write permission on squeakvm.org... do you know who I need to ask for?

Re: [Pharo-project] Renaming a Monticello package

by Max Leske

+1 I asked a similar question just recently: Hi This is probably known but I figured I'd report it. Just in case. First of all, I couldn't figure out how to actually remove a package from Monticello. Unloading it simply emptied it but it would still show up in the list. Would be nice to have that. Now to the actual problem: suppose I have a package named 'FooBar'. Now I want to rename that package to 'Foobar'. I encountered the following things while trying to do this: creating a new package 'Foobar' does nothing. The old package stays in the list but I get no notification about what went wrong. trying to load the old package with the new name from Sqeuaksource through Gofer fails: Gofer new squeaksource: 'TheFoo'; package: 'Foobar'. I think this is the correct behaviour. creating a new package named 'Foobar' in a fresh image (so that the old package is not loaded in Monticello) and trying to save it to Squeaksource results in a notification telling me that the package I want to create already exists (it's messing it up with the old package).
