[Pharo-project] image format with shebang

by Camillo Bruni

how hard would it be to change the image file to include a shebang on the first line? for instance: #!/usr/bin/env pharo -headless like that images would serve as "almost" script files? I image something like everything until the first 0 or newline byte is ignored when loading the image...

The tests show how these work from the point of view of expected behavior, so I think they may be easier to understand by starting with the tests. Dave

Frank I was asked to do a keynote to master, phd student and other and I would like to show them that with the right tool we can do some powerful abstractions. I'm thinking showing them thisContext use for haltIf on:fork: example do you have idea? Should I look (I will ;)) look at Control and DynamicVariable? Do you have other idea?

The idea's not terribly complicated - close over a variable and use resumable exceptions to refer to it or change it - but if you don't have that in-a-nutshell idea in your head it can look a bit strange. But the tests in ControlTests' DelimitedDynamicVariableTest show quite clearly how dynamic binding works. (The delimited part probably won't make a lot of sense until one's managed to wrap one's head around control operators - shift, in this case - so the nice interaction between the delimited continuations and the delimited dynamic variables might be lost on a newbie.) frank > -- > Damien Cassou > http://damiencassou.seasidehosting.st > > "Success is the ability to go from one failure to another without > losing enthusiasm." > Winston Churchill >
