"Simple scripts" (e.g. block as the target)
Last updated at 5:47 am UTC on 4 March 2018
Simple scripting is done in a Workspace.

You can write "fake scripts" for some kinds of objects, avoiding the need for Players, by setting blocks as the target for pluggable morphs. For example, let's say you want to load a remote piece of code from a project:

 | b |
 btn := SimpleButtonMorph new.
 btn label: 'Load updates'.
 btn target: [HTTPSocket httpFileIn: 'http://example.com/squeak-updates.st'].
 btn actionSelector: #value.
 btn openInWorld.

You can have a lot of fun with this. In this way, you can create "scripts" behind buttons and other pluggable morphs that do just about anything. The blocks that are attached to the buttons will be saved and loaded with your project, just like any other object.

A simple script with a class as target

 | btn |
 btn := SimpleButtonMorph new.
 btn target: Project.
 btn label: 'up'.
 btn position: 20 @ (Display height - 40).
 btn actionSelector: #returnToParentProject.
 btn openInWorld.

A script where a block is used two times to create a morph: 500 calculi

Have a script which writes content to a stream and then use Open a Workspace with content.
Create a button for that script with by selecting it and choosing the menu 'button' for it.
The result is a button which creates a report.

Project current world goBack -- button for it

Another idea is to construct a button which opens a window with a graphical display of the thumbnails of all projects.
This is explained in Recipe: Graphical display of all projects.
