No, I don't think so, it has a function. Some people like to configure Pharo images so that they have a running server inside them. In that case, starting your app is a simple as starting the image, but you would probably need the --no-quit to prevent it from exiting immediately. (I personally don't like and never use that approach, but I know some people like it). The confusing aspect is that the same option is used in two places and the first one annihilates the second. But that is documented: prometheus:pharo5 sven$ ./pharo Pharo.image --help Usage: [--no-preferences|--preference-file=<FILE>][<subcommand>] [--help] [--copyright] [--version] [--list] [ --no-quit ] --help print this help message --copyright print the copyrights --version print the version for the image and the vm --list list a description of all active command line handlers --no-quit keep the image running without activating any other command line handler <subcommand> a valid subcommand in --list Documentation: A BasicCommandLineHandler handles default command line arguments and options. It clearly says "without activating any other command line handler". So using --no-quit BEFORE the subcommand annihilates the subcommand (AFAIU).

So --no-quit should be removed from the default line handler?

But you cannot use it as a general command. If you use a subcommand (most likely) then you do not have it unless the subcommand defines it.

Indeed, it works. Thanks!
But the command line usage is not clear : ./pharo Pharo.image Usage: [--no-preferences|--preference-file=<FILE>][<subcommand>] [--help] [--copyright] [--version] [--list] [ --no-quit ]
Maybe, it can be : Usage: [--no-preferences|--preference-file=<FILE>][<subcommand>] [--help] [--copyright] [--version] [--list] [ --no-quit ] [<subcommand args>]
Moreover, an option can usually be placed anywhere on the command line, shouldn't it? Or at least it should raise an error?
Yes it is a bit confusion (but you could try to read/understand the Pharo code, it is not very difficult ;-)
But the idea is that the sub-command controls its own options (like passing linker options via the compiler to the linker - git also has global and per sub command options, no ?)
--no-quit probably also works for the default command ... (I haven't looked), so at that point, the option is consumed already.
No, it doesn't :)
prometheus:pharo5 sven$ ./pharo Pharo.image printVersion [version] 5.0 #50510 prometheus:pharo5 sven$ ./pharo Pharo.image --no-quit ^C
The last command 'hangs' (i.e. the image keeps running, just as advertised). So the default (Pharo, subclass of BasicCommandHandler) interpreted the -- no-quit and acted upon it. No ?
Yes! See: BasicCommandLineHandler>>handleArgument:
