Problem 7: Self-replication

[ghost]

The classic coding golf problem: the quine. Write a program that produces itself as output!

Not very clever (except for the raw string trickery), but it works.

main(){char c[99]=R"(printf("main(){char c[99]=R\"("),printf("%s)\";",c),printf("%s",c);})";printf("main(){char c[99]=R\"("),printf("%s)\";",c),printf("%s",c);}

[ghost]

A slightly more clever Bash script:

for f in *;do if [ -f "$f" ]&&[[ -n $(sed -n '/^for f in/p;q' "$f") ]];then cat "$f";fi;done

"Optimized" for size of source. Not optimized for anything else… including cleaning up after itself or basic error handling.

package main
import _ "embed"
import "os"
//go:embed main.go
var q []byte
func main(){f,_:=os.Open("main.go");f.Write(q)}
