TL;DR: Learning Smalltalk
- Run Pharo http://pharo.org/
- Use Moose http://www.moosetechnology.org/
- Try SmaCC https://github.com/ThierryGoubier/SmaCC

Extract the data, build model
wget .../jdt2famix-bin-1.0.3.zip unzip jdt2famix-bin-1.0.3.zip git clone --depth 1 git@github.com:rastaman/argouml-maven.git cd argouml-maven mvn dependency:copy-dependencies -DoutputDirectory=dependencies -DoverWriteSnapshots=true -DoverWriteReleases=false ../jdt2famix-1.0.3/jdt2famix.sh -
Open Moose: World (click anywhere) -> Moose
-
Load the model: MSE (right corner) -> coose "argouml-maven.mse"
-
Select just loaded "argouml-maven" model
-
Select "All methods"
-
Visualize all/@Deprecated methods
view := RTMondrian new. view shape circle if: [ :each | each isAnnotatedWith: 'Deprecated' ] color: Color red. dep := (self, ( self flatCollect: #clientTypes ) ) asSet. view nodes: dep. view layout grid. view
- World (click anywhere) -> Tools -> SmartCC Parser Generator
- Simple grammar
<number> : [0-9]+; <whitespace> : \s+; Expression : Expression "+" Number | Number ; Number : <number> ; - add Scanner/parser names
Options -> Scanner Class
Options -> Parser Class
- File -> Save
- Test tab

+ image-based approach to programming (Docker/VirtualBox)
+ everything is an _object_ (blocks, control structures, etc) that sends _messages_
+ Less is more: No type declarations, no primitive objects,
no generic types, no modifiers, no operators, no inner classes,
no constructors, and no static methods
+ Awesome tooling: System Browser, Spotter
+ at least single VM tree: https://github.com/OpenSmalltalk/opensmalltalk-vm
+ Existing grammars in SmaCC: JS, Java, C/C#, etc
- fragmentation of the world: VisualWorks, Dolphine, Squeak, Pharo, GemTalk, ...
- external Pharo-launcher to manage VMs/Images that the OS app loads
- no propper default keybidings support for editors :/
