connection string etc
by Jeff Gray Nov. 18, 2016

Nov. 18, 2016

I'm playing around with Garage. Initially it was easy to get a connection to MySQL and return some rows, so I'm looking forward to using it. Where would you typically keep a connection string, considering it also includes a password? An ini file? That seems rather old school :-) Or is there a better way than just storing a string? -- View this message in context: http://forum.world.st/connection-string-etc-tp4923518.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

I've never used magritte or QC magritte and was wondering whether with the momento it qas also possible to get multi step undo cheaply if it didn't already exist. Thanks Paul

Is it possible to file out a class hierarchy ?

>From a playground or nautilus is is possible to file out a class and all of its subclasses into one file out? The subclasses are in different packages, which I think is a confounding factor. Thanks Paul

I'm not sure what you mean with initialize. If you think about creating the collections in mongo then you have to do nothing. Collections are created automatically as soon as you access them the first time.

Hello. I'am using pharo 4.0 with external mongo database (mongolab.com) I have like 7 classes which are voyageRoot. I want to know if I will initialize mongo in each class or in which class I can implement it. Thanks

Re: [Pharo-users] Pier3 with latest Pillar?

For me, Pillar was a package in Pier, and Pier was a tool that I used for all my presentations, prototyping, and small or short-lived community and not-for-profit projects. I do not get why you cannot use Pharo for that. Le 17/11/16 Ã 02:04, Jupiter Jones a Ã©crit : > Hey Stephane, > >>> It would be nice to see Pillar return to being a cross platform project as well.

Which packages? > I also feel my smalltalk-ability isnât up to the standard of so many of the amazing people contributing, which makes me a little reticent to get involved in the more complex projects. You see fixing a comment or adding a test should be possible. Don't hide yourself behind this argument. >> I will see if the trait usage make sense and can be removed.

Their constraints are even greater since they have a large commercial install base supporting many platforms. Come on. Pharo too and we have far less ressources!!! > We should be able to be more flexible and dynamic > >> Because you see Pharo will use more and more slots because they are really really cool and powerful. >> What do you do with Pillar?

Ok then you can still use an old version of Pier and hope that others will do what you want. >>> Iâd like to see Pier get some love - itâs an awesome tool.

Is there any chance that the Smalltalk project could also move there? It would make it easier to fork and hack and make versions available to test before deciding what might be valuable pushed back to the core project. Why easier? You cannot produce a slice? Seriously I will not move pillar to github before Pharo has a fully working solution. And I will maintain pillar but I need time. > > Thanks for all your excellent work with Pillar - not to mention everything else! > > Have fun! > > Jupiter > >
