RAD type hints

[Sophie]

How do I type-hint to get a Ruby function

def show(s)

...

end

to become something close to

void show(const char* s) { ... }

By default it becomes:

void show(void* s)

I tried

def show(s)

"" + s  ## or  s + ""

...

end

With no success. 

Should I be avoiding passing params around? 

Thanks!

try a @s = "c" and use in def show(@s) . as a hinting to the
translator ...

Tried it, but def show(@s) won't compile as it sees @s as instance
variable.

i declare a
@s = 'c'
gets to a
char* __s = "c"; in .cpp

use that in def show <do whatever with @s> end

is it the programming style you are after ?

Not quite, though it is good to know it will work as a backup.

I was hoping to get the method input parameter to type as a char*,
rather than use @instance / global variables for all information
passing.
