Today we'll take a look at the normal development process in VA Smalltalk using ENVY. The general pattern works as follows:

  • Create a Configuration Map
  • Create your Application(s) and add them to your configuration map
  • Create your classes and extensions with your application(s), versioning and releasing the classes as you develop them
  • Leave the Application(s) and Config Map "open", only versioning them as you reach development checkpoints
  • As you begin work each day, load the latest open edition of the config map

To start, create the config map:

Config Maps

Now create the Applications you need, and write code inside of them:


Version and release the classes in your Applications, leaving the Applications "open":

Code Release

Make sure you add all of your Applications to the config map, in the correct order for loading. Also specify the necessary pre-reqs. If you mess this up (i.e., the map won't load), don't worry - you can edit the config map details without having it loaded:

Config Maps

Now, as you begin each working day, load the latest open edition of the config map, with all developers working within the open edition:

Load Config Map

You only need to version and release the Applications and Config Map as you reach checkpoints. When and how you reach them will depend on your process, of course - but the process we've sketched here is the one you'll want to follow.
