[TxMt] Getting one character from the keyboard for use in Commands

Hi all,

I'm new to TM and trying to implement a Command that fills the current selection with a character. Right now I have a simple program that replaces every character in the current selection with a space character (but skips CR/LF), so far so good.

main() { char *x=getenv("TM_SELECTED_TEXT"); char c=32; /* Space character - this is what I'd like to be able to replace at invokation time */ for ( ;x && *x;x++) putchar((*x==10 || *x==13) ? *x:c); }

Now I'd like it to fill the selection not just with a space, but with a user-entered character...

Ideally I'd like to:

1) select an area of text 2) press ^F (or whatever) 3) get a character from the keyboard 4) use that character to fill the selection

How do I accomplish #3 above?

Thanks for any pointers,

Chris
