As Sebastian said, #-> is a message that creates an Association, with the receiver as the key and the argument as the value of the Association. This has actually been around a very long time, though perhaps it's getting more widely used these days. It doesn't appear to be in the Blue Book, but I think it was probably actually in the Smalltalk-80 image 1 release. I'm not *quite* curious enough to verify that by rooting around in my basement for the machine that actually runs that version and seeing if it will still power up after all these years. :-) Regards, -Martin

Hi Bruce, good to see you around, again! The arrow is an Association in short... Sebastian Am 29.11.2016 um 18:48 schrieb Bruce Prior: > I have been away from smalltalk coding for a while.

Use of -> in Pharo Code

by Bruce Prior

I have been away from smalltalk coding for a while. On returning to the fold, I often see the use of a right arrow in code. Is this something new? Today in a Teapot app example, I saw, Teapot on GET: '/welcome' -> 'Hello World!'; start. What is the arrow for?

Tobias Pape wrote some vm changes that solved the problem this summer, and they somehow interfered, so were reverted. I posted some pictures on twitter 10/11-7 of it working with both Pharo & Squeak.

Maringolo Yes, I do the same, but that's precisely what I want to avoid. Having a setter for the sqlite binary makes it friendlier for new comers, by having the setup done in the image side, instead of the OS side, so you don't need to locate your VM (I don't know where it is in the case of Pharo Launcher) and even making it available if you have several VM and images without symlinking each time. Cheers, Offray

In Unix you can create a symlink at the vm directory pointing at the location of the shared object. That's what I do. Regards! Esteban A.

UDBCSQLite and the location of the sqlite3 binary

by Offray Vladimir Luna CÃ¡rdenas

Hi, From time to time, we use UDBCSQLite for our workshops and interactive documentation examples and is a pretty good project for bridging the Smalltalk world and the relational database world. A common glitch is locating the binary of sqlite3 for 32 bits and putting it in a place that is available for the VM. I just make this small hack: === UDBCSQLite3Library>>#library Smalltalk os isMacOS ifTrue: [ ^ #sqlite3 ]. Smalltalk os isUnix ifTrue: [ ^ '/usr/lib32/libsqlite3.so']. ^'sqlite3' === and now is working pretty well on my machine. Of course, this only works on Arch 64 bits and its derivates and could change in other Gnu/Linux variants. So, I'm wondering for a better way to make the path to the sqlite binary not hard coded into UDBCSQLite3 and creating some #library: setter that lets the user to setup the sqlite3 location if the file on UDBCSQLite3Library>>#library is non-existent or wrong. I'm sending this to the list, because AFAIK there is no ticketing on STHub to discuss code issues. Cheers, Offray
