Defining the UI

The main feature we want for the rewriting tool UI it’s to be example driven. Two very similar examples:

Option 1 – All in the same view

Option 2 – A tabed view

Option 3 – A 3-Column layout

We also want to be possible:

• select a method and drop into the example text editor.
• manipulate the ASTs nodes in the text editor to make simple define transformations and matching.
• highlight the matched parts from the example.
• select scopes to apply the rule.
• preview the changes.
• show the transformation in the example expression.
• modify an expression throw the example or writing the pattern.
• output the smalltalk valid code that produces the effect we see in the example.
