Launcher does not properly pass through -X properties on Windows

[headius]

This could be some oddity in how powershell passes arguments through to our launcher:

PS C:\dev\jruby> jruby -Xbacktrace.style=raw -e 1
jruby: warning: unknown property jruby.backtrace
Error opening script file: C:/dev/jruby/.style=raw (The system cannot find the file specified)

The . is improperly being treated as the end of our argument. PowerShell appears to be splitting incoming arguments at .. I'm not sure how to fix this in the launcher other than detecting we're on PowerShell and de-mangling those arguments :-(

This is running from a self-built clone, rather than using installer.

As expected, it does work with cmd.exe. So this is specific to PowerShell.

The stop-parsing symbol can be used: jruby --% -Xbacktrace.style=raw -e 1

Or just quote any arguments which contain a dot (or any other special characters): jruby "-Xbacktrace.style=raw" -e 1

Quoting the dot should actually be enough, but it looks weird.

@cremno Ahh thank you, that's a neat workaround.

@cremno Do you know what we should be doing differently in the launcher (C++)? It's incredibly inconvenient that PowerShell processes arguments differently than cmd.exe :-(

[cremno]

@headius: I think you can't do much (non-hacky) in this case. The command line is always “mangled” since PowerShell does its job before creating the process and passing it.

PowerShell should be considered for the in-progress rewrite of this launcher.
