parsing "arguments" in C++

Question

I am implementing a game in console.

I need to parse strings with escaping, I just cannot split string by space to get parameters. if one of arguments is "Hello my name is \"someone\"" then i should get string >Hello my name is "someone"<

example:

move_player "La la" 10.0 20.0 10.0

this should give me 4 parameters, where I don't count command name.

setplayerid "La la" 24442
rename_player "La la" parameterwithoutquotes

Is there any library for such thing?

Take a look at boost::tokenizer

Use escaped_list_separator, which separates a string using given character preserving text in quotes.

couldn't you just use the spaces as a delimter to extract all info from the string?

sorry: mist the part about not using space.

Spaces are usually used to separate arguments. If you'd like to provide ability to enter argument with spaces inside you have to escape them somehow.
