I am trying to understand the difference between using quit and save/quit. exitSuccess never gets called when both options "--save --quit" are given. Shouldn't the code handle this case as well: > > (self hasOption: 'save') > ifTrue: [ Smalltalk snapshot: true andQuit: false ]. > (self hasOption: 'quit') > ifTrue: [ self exitSuccess ]. Yes, I think so. But you have to be careful there. Imagine that you first save with "Smalltalk snapshot: true andQuit: false" and then you check for 'quit' and send #exitSuccess. What will happen after the next startup is that the execution will arrive at the *same point*. It will check 'quit' and exit as before, you will not be able to get back in to the image. You should definitely try playing around with that, just be sure to make a copy of your image first :) Cheers, Max > > Regards .. Subbu >

I am trying to understand the difference between using quit and save/quit. exitSuccess never gets called when both options "--save --quit" are given. Shouldn't the code handle this case as well: (self hasOption: 'save') ifTrue: [ Smalltalk snapshot: true andQuit: false ]. (self hasOption: 'quit') ifTrue: [ self exitSuccess ]. Regards .. Subbu

Yes. #exitSuccess does a bit more: 1. return an exit code to the command line 2. print a message 3. check if the session has changed 4. allows for overriding and special handling of the Exit exception. You should not assume that nobody needs that :) Cheers, Max > > Regards .. Subbu >

Current working directory

by Rajula Vineet

Hi all, I am working on improving pharo command line as a part of my GSoC project. I have been looking at different current working directory implementations. I have written a blog post <https://vineetreddy.wordpress.com/2017/05/17/pwd-vs-getcwd/> on it. It would be of great help, if you can take a look and give your feedback.

Command line save and quit

by K K Subbu

Hi, STCommandLineHandler>>#end is defined as: --- | quit | quit := self commandLine hasOption: 'quit'. (self commandLine hasOption: 'save') ifTrue: [ Smalltalk snapshot: true andQuit: quit ]. quit ifTrue: [ self exitSuccess ]. --- Can this be simplified to: ^Smalltalk snapshot: (self hasOption: 'save') andQuit: (self hasOption: 'quit') Is it necessary to call exitSuccess when only '--quit' is given? Regards .. Subbu
