[Pharo-users] Re: Error in Pharo 9 under Windows 10

[Markus Wedel]

Dear Nacho,

I think you could press the gears icon in the top right corner of the Pharo 
launcher window, then mark the desired virtual machine, then update the 
installed vm via right-click.
Or you could delete the existing virtual machine and it should automatically 
install a new one when launching a Pharo Image.

Best regards
Markus

[Pharo-users] Re: Sharing classes between packages

Hi David,

Indeed, you should move it to another package.
However, this package should either:
    be in its own repository
    load it with the initial project
        In this case, you'd have to clone the whole initial project and 
load only the package that you want to share, which can be quite big.


Either way, you'll have to tweak the baseline, as you can read about 
here: 
https://github.com/pharo-open-documentation/pharo-wiki/blob/master/General/Baselines.md


Hope this helps.
Pierre

I have a small Key/Value database that I have written for my
Seaside apps. I have one Package - Family-Accounts which defines
the classes for this database. I am now writing a new Seaside app
(IPMSClacton) that will also need to use the database. How do I
share the code between the two packages?

Thanks, will try to do that. I know how to do it by downloading everything
by myself.
But how do I do that with Pharo Launcher?
Cheers,
Nacho

[Pharo-users] Re: Strings in Playground are read only in Pharo 9

[Richard O'Keefe]

For what it's worth, the ANSI Smalltalk standard says
"The protocols specified for literals do not include any messages
 that modify the state of the literal objects.
 The effect of sending a message to an object that is the value
 of a literal that modifies the state of the literal is undefined."
This also includes trying to modify an array literal, and fiddling
with the bits of a large integer.

That is, according to the ANSI standard, 'abc' is a string but not
necessarily a String.  I hope that is clear (:-).
