How does Pharo execute classes from the command line?

You can pass the filename of a .cs/.st file to the VM that gets
filed-in on startup.

Is there a way to specify the class and the method to be called?

Not directly.

Are command line arguments available?

$ squeak --help
Usage: squeak [<option>...] [<imageName> [<argument>...]]
      squeak [<option>...] -- [<argument>...]


BTW, dunno if it's a crossplatform Cog issue ( haven't checked others) but in John's new OSX Cog-based VMs (last tested 5.8b9), it doesn't look like the arguments are present in systemAttributes at position 2 onwards.
Thus, ProjectLauncher will fail to execute scripts at all.


In -help:
 -encoding <enc>       set the internal character encoding (default: MacRoman)

Sounds strangel, should probably be updated to Latin1/ removed (depending on how it's actually used)?


I bet less than 1 out of 1000 machines running squeak shall use this
MacRoman thing nowadays.

Just ran -help on 5.2.5 and 5.8b9, the -encoding option is not mentioned in any of those.

The only current use case I could think of would be Cuis, who might want to set it to Latin15 in order to interpret � correctly.
Sure, the StrikeFonts (taken from Cuis) included in Pharo/Squeak actually cover Latin15 as well, but everywhere else, encoding of ByteStrings is assumed to be Latin1... 
So better with some visual discrepancies, namely displaying � as �, � as ?, etc. than reading/writing the wrong characters to/from external sources
