    ## Objective

    1. Run Pharo http://pharo.org/
    2. Use Moose http://www.moosetechnology.org/
    3. Try SmaCC https://github.com/ThierryGoubier/SmaCC

    ### 0. Installing & Launching Pharo VM
    ```
    brew cask install pharo-launcher
    # Chose Moose 6.0
    # follow http://themoosebook.org/book/index.html#h1mooseinanutshell
    Pharo6.0.app/Contents/MacOS/Pharo Pharo6.0.app/Contents/Resources/Pharo6.1.image
    ```


    ### I. Simple Smalltalk program

    World (click) -> Playground

    ```smalltalk
    ProfStef go. (cmd+d to evaulate, using "Do It")
    a := OrderedCollection new
    add: 1;
    add: 2;
    add: 3;
    yourself.
    a. (cmd+p to print)
    Number extend [
    my_factorial [
    (self < 2) ifTrue: [ ^1 ]
    ifFalse: [ |c|
    c := OrderedCollection new.
    2 to: self do: [ :i | c add: i ].
    ^ (c fold: [ :a :b | a * b ] ) ]]].
    7 factorial.
    7 my_factorial.
    a := OrderedCollection new
    add: 1;
    add: 2;
    add: 3.
    Transcript show: a.
    ```

    Built-in tools and commands:
    - **Playground/workspace**: "Do it", "Print it", "Insepct it"
    - **Transcript** as `console.log` or `System.out`
    - **System Browser** message or cmd+b
    - **Spotter** - just Shift+Enter
    - `#class`
    - `#implementor`




    ### II. Code visualization using Moose

    - 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

    ```smalltalk
    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
    ```

    ### II. Code visualization using Moose

    - 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

    ```smalltalk
    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
    ```




    ### III. Simple parser using SmaCC

    - 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
    ```
    3 + 4
    ```
    Validate: (Select text) -> Evaluate
    Inspect AST: (Select text) -> Inspect




    ### IV. add Smalltalk to Excercism.io
