Installation

FAST-Pharo comes with an importer defined with the SmalltalkImporter based on PetitParser moose project parser. To install it, execute the following script:

It can take time

Metacello new
    baseline: 'FASTPharo';
    repository: 'github://moosetechnology/FAST-Pharo:v2/src';
    load: 'importer'.

This script installs the FAST project, the PetitParser project, the FAST-Pharo project, and all the dependencies.

Import

The FAST-Pharo importer allows one to import AST of a method or of a class. To import method, one must use the method runWithSource:.

For example, the following script import the method testVisitInheritance of FamixMMUMLDocumentorVisitorTest

FASTSmalltalkImporterVisitor
  new runWithSource:
    (FamixMMUMLDocumentorVisitorTest >> #testVisitInheritance)
    sourceCode

Tools

One nice way to explore a FAST model is to use the source code and the tree extensions of the inspector. It allows one the navigate in a FAST model and see the code corresponding to each node.

To use it, execute the code to create a model with Ctrl+I. It opens an inspector on the imported model.

Then, select a method entity. On the right-hand pane of the inspector, select the Tree tab, on the left-hand pane, select the source code extension. The source code is highlighted and the area selected corresponds to the entity selected in the right-hand panel.
