want the command line arguments to be non-quoted?

Example:
spawnProcess(["SomePath\\Test.exe"], ["-silent"]);
and the command line becomes: "SomePath\Test.exe" "-silent" (with 
the quotes exaclt like shown).

Unfortunately (for some strange reason), the spawned process only 
responds to non-quoted arguments passed through the command line. 
So the command line should be exactly: "SomePath\Test.exe" -silent

Is there any way to achieve this?

I can't reproduce this on OS X with 2.066rc1 (args are unquoted).

Can someone else check Windows? Sounds like a bug to me.

Arguments on POSIX systems are passed to programs in a different 
way than on Windows. On POSIX, the arguments are passed as an 
array of zero-terminated strings (when a command is given as a 
string, a shell breaks it up into an argument array before 
running the program). On Windows, the arguments are passed as a 
string, and are parsed into an array by the executed program (or 
its language runtime). Although generally Windows programs use 
the OS function CommandLineToArgvW, they have no obligation to do 
so, and may implement their own algorithm.

I assume you mean:

No, there currently is no way to achieve this using spawnProcess. 
You could have better luck using spawnShell instead.

I would consider such behavior a bug in the application you're 
trying to run, as it does not perform command-line parsing 
according to convention (CommandLineToArgvW).

It would be possible to enhance spawnProcess and family to only 
quote arguments which need to be quoted, which would fix this 
particular case, however of course that can't address every 
program which parses its command line in a non-standard way.
