Hi Pierce, I'm not sure if I am understanding your question, but please have a look at PipeableOSProcess class>>tkExample. This is an example of having your image talking to a REPL shell, /usr/bin/wish in this case, but probably similar to a sqlite3 shell. The wish shell is a tclsh interpreter with Tk gui, so I expect that is close to what you are trying to do. If you are interested in having your squeak/pharo image be the REPL server, then class ExternalCommmandShell may be closer to what you want. Dave

Re: [Pharo-users] Reading rows in a database table (select * from ...)

[ resultSet := db execute: 'select * from posts limit 10'. [ (row := resultSet next) notNil ] whileTrue: [ coll add: row ] ] ensure: [ db close ]. coll inspect. Each row is an NBSQLite3Row instance. Use #at: with the column name as key to get at the data. coll fifth at: 'Title' ==> 'How do I calculate someone''s age in C#?' With the collection you still have to loop through them, no? I am using NBSQLite3 to play with existing data, and I haven't worked with enough different types of data to attempt to generalize a looping construct. So I've always done by-row processing. Another reason is that, while my data sets aren't "Big Data", I am aesthetically inclined against reading everything into RAM. :-) Above example uses the Sep 2011 StackOverflow data dump. The SQLite datafile created from the dump, with full text indexing, is 16GB and the table posts has ~6.5 million rows. HTH. Pierce

Esteban, Imagine I do have already the ConfigurationOfMyApp (with everything already setup). I want to commit multiple packages together. By that I mean: 1) Wanna see a "Changes" from all dirty packages of my Configuration 2) I want to write same commit message for all 3) Commit all packages to the correct repository But...I do not want to create a new version in the ConfigurationOfMyApp nor commit it. Can I do that? Thanks in advance, On Thu, Apr 30, 2015 at 7:43 PM, Pablo R. Digonzelli <pdigonzelli(a)gmail.com> wrote: > Esteban, Versionner menu options in Monticello does not work in pharo > 4.0.

Truth is because I don't know how. I could look, but I know myself, and I'll type "Workspace open" a thousand times before doing it. There are 978 to go... :P However now it is confirmed that this omission was "by design", I think it was a bad decision, whatever is the rationale behind it. I'll get used to it, but I can bet really hard that newcomers won't. Regards! Esteban A. Maringolo
