Hi Werner, Aha. So, you want to compare multiple runs of the same code? Do you use the print-it for anything else?

one thing, i guess it could eventually be preferable if the comment would go on the next line so that one can repeatedly evaluate or print that line. this is at least a common use case for me. werner On 01/19/2015 10:01 AM, Werner Kassens wrote: > Hi Doru, > works nicely and makes the playground for the first time actually usable > for me. i like the way it works: the automatic commenting and that i > only need to press enter. > werner > > >

Re: [Pharo-users] NBSQLite3 on OS X - Pharo 3

by Guillermo Polito

Hi Mircea, - About the library: You can either install the sqlite library close to the VM or, as mac is a unix, in /usr/lib. I have for example mine in here: /usr/lib/libsqlite3.dylib The VM loads the libraries dinamically, so putting the library in one of those locations should IIRC by default look at those places. - about the db file: do you already have a db file you want to open? Usually the db file is next to the image again IIRC ^^. What you can actually try is opening an unexistent database, what will create a new file for you. That will give you an idea of where the database file should be placed. Hope that helps, Guille El Mon Jan 19 2015 at 9:54:56 AM, Mircea S. <mircea(a)unom.ro> escribiÃ³: > Forgot to mention I want to use a *relative path* if at all possible. > > > > Pe 19 ian. 2015, la 00:46, Mircea S. <mircea(a)unom.ro> a scris: > > Hello everyone, > > I was looking into NBSQLite3 using the guide on smalltalkhub, pasted it > below. > > 1.

Thanks for the feedback. I am still looking for concrete use cases why people need to see the printout in the editor. Could you provide an example of when you need it?

improving print-it in playground

by Tudor Girba

Hi, I worked with Andrei to find a solution for improving the print-it support. You can take a look here: http://www.humane-assessment.com/blog/improving-print-it-support-in-gtplayg… The current solution can be found in the latest Pharo image.
