[Pharo-project] Logging into squeaksource(3)

by Sean P. DeNigris

This snippet is very useful, but it would have to be reapplied when new repos are added: repos := (MCWorkingCopy allManagers gather: [:e | e repositoryGroup repositories]) asSet. squeaksourceRepos := repos select: [:each | (each isKindOf: MCHttpRepository) and: [ each locationWithTrailingSlash beginsWith: 'http://www.squeaksource.com'] ]. squeaksourceRepos do: [:each | each user: 'user'; password: 'password']. I'm imagining an in-image mechanism to provide credentials to various online repos and then new http repos should automatically be fed those credentials. anObject forReposAt: 'http://www.squeaksource.com' loginAs: 'user' withPassword: 'password'. And then automatically add this info to new repos at that host.

The export to RTF is done and used for ExtendedClipboard (currently only supported on the 4 series Mac VM). It would be trivial to add support for saving RTF files, but RTF can not hold all the features StyledTextEditor supports, so it is better to use own format.

[Pharo-project] old version of ProfStef in latest pharo1.4?

by Guillermo Polito

Pharo1.4 Latest update: #14438 - If I tried to open ProfStef --> DNU. - Then I looked ProfStef packages and they are oldish. - Open Configuration browser, select ConfigurationOfProfStef, load stable - open ProfStef -> all ok :) http://code.google.com/p/pharo/issues/detail?id=5705&thanks=5705&ts=1335465… Guille

[Pharo-project] What about making the configuration browser more visible?

by Guillermo Polito

What about naming it "Package Loader" or "Package center" or something like that? And putting it in the main menu instead of inside of Tools? I want people who open pharo for the first time to say "Hey, here I can download stuff!!!" Guille

Re: [Pharo-project] Editor focus & hotkeys

by blake

> Most of Pharo's focus problems can be solved by simply flipping two preferences: > > Â Â Keyboard focus on mouse down Â ::: Â set it false Â (instead of true) > Â Â Lose keyboard focus when mouse leave Â ::: Â set it true Â (instead of false) Well, the problem I have with that is that my mouse is on a slippery, uneven surface. Heh. So I only want mousing to mean something when I want it to. Heh. Figure THAT one out. No, with the hot keys I'm doing okay, except it'd be easier to have some kind of indication of focus. ===Blake===

The other is kind of experimental yet, and is on another repository...

Re: [Pharo-project] OSProcess - is process done?

by DeNigris Sean

> Hi Sean, > > An fread() call will block when reading from a unix pipe unless the pipe > end has been set to nonblocking mode (see #primSQFileSetNonBlocking:). So the #upToEnd problem was solved by sending #setNonBlockingOutput. So the following simple in-image ssh client works: p := PipeableOSProcess command: '/usr/bin/expect /path/to/expect_file.exp ', password, ' ', ipAddress. p setNonBlockingOutput. "This was added. Otherwise, #upToEnd hangs the image" p nextPutAll: 'ls', Character cr asString. p upToEnd. p nextPutAll: 'pwd', Character cr asString. p upToEnd. The reason that I didn't think to do this before is that I thought the whole point of #upToEnd was that it was *inherently* non-blocking... > - Open a test runner and run CommandShellTestCase... Yes, they all passed except the PipeableOSProcessTestCase ones... The other problem ("p := PipeableOSProcess waitForCommand: 'ps -ax -o pid,command'" hangs forever) is not happening right now. It's returning as soon as the process is finished, so I'll have to get back to you if it pops up again... Thanks for all the help! And is a fix required for #upToEnd based on the above? Sean
