Re: [Pharo-project] NonInteractiveTranscript holds reference to closed files

by Sven Van Caekenberghe

I am hitting this too now ;-) So what will we do ? The simplest solution seems option 2 with the improved #close behavior. I will make a slice tomorrow.

EvaludateCommandLineHandler>>activate self evaluateStdIn. self evaluateArguments. self quit. always triies to read from stdin, so it needs a crtl-d to end, reading nothing, printing nil, only then will the args be evaluated as you describe. It goes like ubuntu@ip-10-48-234-254:~/pharo2$ ./bin/CogVM -vm-display-null -vm-sound-null Pharo-2.0.image eval 1+2 <CTRL-D> nil 3 ubuntu@ip-10-48-234-254:~/pharo2$ Maybe it also depends on whether the invocation is from an interactive terminal or a shell script..

But I have to do a ctrl-d to end the input and have it evaluated and printed. And then the image quits, no repl loop ? There was an issue with that Guillermo reported, so for now this has been deactivated. You have to explicitly enable the 'eval' handler to read from pipe in. So far it will just try to read from stind unit it #atEnd returns true, I guess that is not fully compliant with the standard behavior of linux scripts :P REPL: I have a multiline history repl in alpha state: http://smalltalkhub.com/#!/~dh83/readline It currently needs some more documentation, but I guess I can make it go into the 2.0 default image next week or so, then people can start to give some feedback. > Also for the eval option, it does not work, unless I do a ctrl-d manually.

Not on purpose, sorry :). I'll provide a slice to reintegrate that.

Igor I rebuild everything based on 1.2.1 and it loads and the example works now as soon as I save the image I cannot open it anymore. So I will work why the image of fernando.

[Pharo-project] New Command Line Behavior

by Sven Van Caekenberghe

Hi (Camillo), Is there some place that describes the new features of the command line ? ;-) I was just trying a bit right now (in Linux, latest VM, latest mage). It seems that just starting an image with no args results in it reading an expression from stdin, right ? But I have to do a ctrl-d to end the input and have it evaluated and printed. And then the image quits, no repl loop ? Also for the eval option, it does not work, unless I do a ctrl-d manually. You once posted this example: ./bin/CogVM -vm-display-null -vm-sound-null Pharo-2.0.image eval '1+2' Should it still work ?

[Pharo-project] SmalltalkImage>>#snapshot:andQuit:

by Sven Van Caekenberghe

Hi (Guillermo), It seems that SmalltalkImage>>#snapshot:andQuit: no longer returns the value of resuming (a Boolean), so that the following in a script to build a new image no longer works: | resuming | resuming := SmalltalkImage current saveAs: 'my-image'. resuming ifFalse: [ Smalltalk snapshot: false andQuit: true ]. Was this intentional ? What is the alternative ? Thx, Sven -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill
