Comment on Envy
By Charles Adams

I find the Envy model vastly superior to that of Store. That should tell you all you need to know about bundles.

Comment on Bundles and Packages
By David Buck

Comment by David Buck

Packages can contain classes and namespaces and forms the smallest loadable entity in Store. Bundles can contain packages and bundles.

Packages and Bundles can both be versioned into Store. When they are, the developer can specify a blessing level which indicates what state of maturity this version is at (broken, development, released, etc).

Packages and bundles can both have prerequisites which tell you what other packages or bundles must be loaded before this one. This list optionally allows you type in a version number to load. If none is provided, it will ask the user which one to load (unless you tell it to default to the latest version with a particular blessing level).

Bundles list their contents in a specific order which corresponds to the load order. When loading, it loads a package at a time so it's important to get the order right so that packages that depend on other packages are loaded after the ones they depend on. If you get this wrong, you can publish the bundle but not load it back in. There's a Validate button in the window that checks these constraints and allows you to change the order if necessary by pushing a bundle or package up or down one element at a time.

A Package contains Smalltalk code declarations only - it cannot recursively contain other Packages.

A Bundle contains Packages and Bundles - it cannot hold Smalltalk code directly.

Comparing with filesystems: a Package is like a file holding Smalltalk code where a Bundle would be directory holding files and nested directories. Unlike a file system a Bundle remembers the ordering of its contents.

Can someone define what a package and bundle is in Visualworks and when you would want to use one or the other?

 

For non-visualworks people that is...
