Info about OMeta/2

Hi,

I’ve been experimenting with OMeta/2. It’s a lot of fun, but there is a reference to the undefined method OMeta2Compiler>>from:class:context:notifying. I implemented this as an empty method and things appear to be working. Could anyone enlighten me as to the intention of this message and why the reference to it exists in the code base?

I suggest you look in Cuis list archives
http://cuis-smalltalk.org/mailman/listinfo/cuis-dev_cuis-smalltalk.org

Look all Phil say and do.
By the way, what Squeak version use you ?
Must made time for re take Ometa, could share any are you doing ?

I like Cuis very much. I’ll check that out.
At the moment, I am using Squeak 5.1 and evaluating OMeta for use in my Principles of Programming Languages class. Nothing of particular interest to share yet.

Thanks Hans-Martin and Bert. As I said, I am just exploring for the time being and I have a hacked a version suitable for those purposes. 

Hi John,

regarding defining new languages in the Smalltalk image, you might also be interested in Ohm/S and Gramada. Ohm/S is the Squeak/Smalltalk implementation of the successor of OMeta/2, which is called Ohm. It is somewhat different than OMeta as it separates a language definition into a syntax definition (a grammar) and several semantics defined in relation to the grammar rules.

You can get Ohm/S at: https://github.com/hpi-swa/Ohm-S

Additionally, I have developed a development environment for Ohm language definitions called Gramada. It includes tooling to see live results of parses on examples and editors with syntax highlighting and tools to navigate between rules via senders and implementors Further, it includes a parsing debugger and SUnit extensions for grammars. You can see a demo here: https://vimeo.com/180190846

A demo version of the environment can be downloaded here: https://patrickrein.de/gramadaDemo/gramadaDemo.zip .

I am also currently working on creating a stable release which will be linked from https://github.com/HPI-SWA-Lab/Gramada.

Bests
Patrick

Thanks. That was the old URL.

For now it resides at: https://www.patrickrein.de/gramada/gramadaDemo.zip
