That looks like the best option alternatively you can use JNIPort that allows to run Java libraries from Pharo. There is also redline smalltalk that is a Smalltalk that runs on top of the JVM. Python also has a very good implementation running on JVM called Jython it can not only use Java libraries but even regular Python libraries .

pondering Smalltalk scripting in Minecraft

by Ben Coman

Minecraft is immensely popular. For teaching programming (to kids) via Minecraft, the first option is Java, but that might be a bit heavy for a pre-teen. A few lighter options are Lua via Computercraft [1] and Javascript via Scriptcraft [2]. I've tried Computercraft and its quite interesting the way it simulates real-life computers and drones, but the drone works slowly so my kids end up doing things faster themselves. I am in the initial stages of trying Scriptcraft (with Spigot server) and making walls, buildings etc is fast, so hopefully my kids will see value in using these superpowers. But then I wondered whether it might be possible for SqueakJS and PharoJS to interface with Minecraft via the Javascript engine. I was interested to discover that the JVM comes with a Javascript engine built in [3], "Rhino" [4] for JVM7 and faster "Nashorn" for JVM8 [5]. So I thought I would just seed the idea in the community to see if anyone might be interested to pursue this. It really would be fantastic to use our environment to make mods for Minecraft. (The actual plan for world domination is to build some assets and experience with minecraft, and then migrate to a pure Smalltalk 3D client and server with GPU backends when that becomes available -gnomes) Or maybe it would be better to use JNIPort[6] or JavaConnect[7] or something else. cheers -ben [1] http://www.computercraft.info/2016/04/01/computercraft-and-computercraftedu… [2] http://scriptcraftjs.org/ [3] https://github.com/walterhiggins/ScriptCraft/blob/master/docs/Using-Java-AP… [4] https://jaxenter.com/scriptcraft-hacking-minecraft-for-kids-105467.html [5] https://www.infoq.com/articles/nashorn [6] http://smalltalkhub.com/#!/~JNIPort/JNIPort/ [7] http://www.squeaksource.com/JavaConnect

Brisbane meet up

by Jeff Gray

I was poking around the internet wondering if there are many smalltalkers in Brisbane (where I live) and came across a group in Meetup.com. There's a monthly meeting and I've signed up. I'm looking forward to seeing what goes on. Turns out there's 36 in the group. I don't know if they all meet but good to know there are more of us out there :-) -- View this message in context: http://forum.world.st/Brisbane-meet-up-tp4925969.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] GitFileTree on Pharo 5.0

by Dimitris Chloupis

you dont need gitfiletree to use git with pharo, I use just filetreee and gitup which an excellent git client for macos You can find the cause of the problem but it wont be simple. This is a C problem not a pharo problem, meaning something is wrong with that library. To really find out what you will need to load the library from C and use the error detection functions to find what is wrong, you could use them from pharo too but you will still need to understand C to make use of the FFI. Unfortunately I cannot help much in this case because its more or less a continuous testing process. This is how I learned to do shared memory via the FFI. Made the code in C first and then ported to Pharo. I had to perform dozens of test to get it right and had to battle with dozens of errors. I have both Pharo 6 and Pharo 5 working fine on my macos sierra , so it must be something wrong with your system.
