Today's Smalltalk Daily looks at adding error handling (for the runtime) via the build script. We're adding the basic stuff from RuntimePackager, but you can customize from there. The build script is just below; You can also just skip to the video
"build a simple app"
"load all my needed parcels - including RTP"
[#( '$(VISUALWORKS)/packaging/RuntimePackager.pcl'
'SampleApp.pcl') do: [:each |
Parcel loadParcelFrom: each]]
on: MissingParcelSource
do: [:ex | ex resume: true].
"turn change log off, so that we can ship patches reasonably"
'ChangeSet.BroadcastChanges' asQualifiedReference
ifDefinedDo: [:flag |
'ChangeSet.BroadcastChanges' asQualifiedReference value: false].
"Set herald string"
ObjectMemory setHeraldString: 'This is an Example Application in VisualWorks'.
"reset parcel path"
Parcel searchPathModel value removeAll.
"set up runtime state"

"set up runtime state (NOTE: This block is commented out

Today's Smalltalk Daily looks at a simple runtime scripting example. I've covered this topic before, but used the (more complex) BottomFeeder application as my example. Here, we take a simple "application" (a class with one method) and a simple subsystem to start it - along with the script to do the build. The script is reproduced below; if you would rather just watch the video, then just go here. I posted all of the code and steps for this yesterday if you would rather take this in textual post form. You can download the example code here.
