hi there,

a funny thing:

--------------------------------
$ cat rgcc
#!/bin/sh
cf=$@
mycf=__`echo $cf|xargs basename`
cat $cf | sed '1d'  > ${mycf}
gcc ${mycf} -o a.out
rm ${mycf}
./a.out

$ cat test.c
#!/home/user/rgcc
#include <stdio.h>
int main()
{
    printf("hello\n");
}
--------------------------------

And then,

----------------
chmod +x test.c
./test.c
----------------

output hello.

is rdmd implemented similarly?

thanks!

Basically, yeah.

rdmd adds a few different features as well, but the bigger thing it does is cache the results in a global temporary directory.  So If you run rdmd on the same file with the same options twice, the second time it won't compile anything, it will detect that it was already compiled and just run it.
