Looks like this calls for a class variable to hold the library location that can be (re)set by the user / application programmer? In NBSQLite3 I have integrated SQLcipher which provides transparent full database encryption for SQLite. I keep libsqlcipher.so separate from libsqlite.so. To switch between SQLite and SQLcipher for the unit tests I remember using a class variable, in what may be called a 'doubleton' pattern. :-) The SQLcipher bits aren't in UDBCSQLite3 yet. I'm also working on using Ansible to deploy VM and images programmatically. Using this mechanism I deploy both libsqlite.so and libsqlcipher.so into the VM directory, so the situation where Pharo cannot find the shared library does not arise. Pierce

Re: [Pharo-users] Use of -> in Pharo Code

Hi Stef, Thanks for the welcome back. I always have fun with Smalltalk in the Winter but each year Summer seems to get in the way. I appreciate your reminiscences, but I still don't understand what the right aero (->) does.
