Moose demo: building a simple code browser

In this demo we exercise Glamour, the Moose engine for building browsers, to build a simple code browser consisting of three columns on top for navigation showing namespaces, classes and methods, and a pane below displaying the source text of the selected method.

The browser supports basic navigation, but it is suitable for an introduction to Glamour because it covers a significant part of its mechanisms, and shows what is accomplishable in a short amount of time.

The code for building the browser is:

composer tabulator with: [:t | 
  t 
    row: [:r | r column: #namespaces; column: #classes; column: #methods];
    row: #details.
  t transmit to: #namespaces; andShow: [:a | 
    a tree 
      title: 'Namespaces';
      display: [:mooseModel | mooseModel allNamespaces select: #isRoot];
      children: #childScopes;
      format: #name ].
  t transmit from: #namespaces; to: #classes; andShow: [:a |
    a list 
      title: 'Classes';
      display: #classes;
      format: #name ].
  t transmit from: #classes; to: #methods; andShow: [:a |
    a list 
      title: 'Methods';
      display: #methods;
      format: #name ].
  t transmit from: #methods; to: #details; andShow: [:a |
    a text 
      title: 'Source';
      display: #formattedSourceText ].
  ].
composer startOn: model.

You can give it a try in the latest Moose.
