[squeak-dev] How to ask Squeak to save the image from outside

Damien Cassou-3
Hi,

I would like to be able to make Squeak save the image from a Windows
.bat script. Is it possible to control the VM and the image once
launched?

Thank you

fork a process that sleeps maybe 10 seconds and on wake up, checks for
a file named, for example,
SHUTDOWN.txt in a given folder. If found then snapshot the image and quit.

Then in the script create and remove the folder on demand.

Something like this:

[
  [
    [ 60 seconds asDelay wait.
      (FileDirectory default fileOrDirectoryExists: '/var/squeak/save.squeak')
        ifTrue: [ SmalltalkImage current snapshot: true andQuit: false ]
    ] on: Error do: [ :error | error asDebugEmail ]
  ] repeat
] forkAt: Processor systemBackgroundPriority.
Project uiProcess suspend.

Based on a script from Ramon Leon.

Or use one of the many networking services Squeak supports and
establish a client/server connection, for example with http.

Does that image have Seaside? If so, you can have a particular URL does that the save. So, then, from .bat you can do something like wget to that URL

cheers,
