Want to test a few lines of C ?

Normally you'd have to :

• create test.c
• write headers #include <stdfoo.h> #include <stdbar.h>...
• write entry-point int main (int argc ...) {}
• write your code
• save
• finally run gcc test.c -Wall -Wbar && ./a.out

Forgot a header ? To link math (-lm) ?
Bad luck... Now you have to edit test.c...

No such hassle with lacy :

$ lacy  
int i = pow(2,8);  
printf ("%d\n", i);  
[CTRL+D]  
256

lacy can also run files.
$ lacy hello.c

If your code has no main(), lacy adds classic headers and puts your statements into main().

$ lacy hello.c  
Hello!

$ lacy hello.c Bob    
Hello Bob!

$ cat hello.c | lacy  
Hello!

$ lacy  
printf ("%s\n", "Hello!");  
[CTRL+D]  
Hello!

$ lacy 'printf ("%s\n", "Hello!");'  
Hello!
