In a headless image, I'd like to do the following: if there's any error, arrange to have a debugger open on the next (headful) launch, and then save and quit.
I'm drawing a blank - how would I do that?
I explored various dead ends, the culmination of which was the image-breaking: actualWorkBlock on: Error do: [ [ Smalltalk snapshot: true andQuit: true ] fork. Halt now ]
Thanks!
Sorry not a solution, but you sparked a side-thought... To avoid sometimes being swamped by Pre-Debug windows. Instead of an error bringing up an individual Pre-Debug window, we could have error go into a queue which a singleton Pre-Debug window could have a view into. This "Error Queue Viewer" would have on row per error, and you click on a row to open a normal debugger, much like you click <Debug> button in the existing Pre-Debug window. In a headless image, the Error Queue Viewer would not appear, but the error would keep being queued until the next time the Error Queue Viewer is manually opened. The same error-queue might provide a similar interface point for Pharo Remote Tools, so you can see errors that occurred while you were not connected. cheers -ben
