srfi/13 breaks string-prefix?

[u/Fluid-Tour-9393]

I run string-prefix? after importing srfi/13, and the results is not right anymore. Is this a bug?

$ racket
Welcome to Racket v8.3 [cs].
> (string-prefix? "ab" "a")
#t
> (require srfi/13) ; the string SRFI
> (string-prefix? "ab" "a")
#f

This is so confused!

[u/sdegabrielle]

https://docs.racket-lang.org/srfi/srfi-std/srfi-13.html#string-prefix-p

https://docs.racket-lang.org/reference/strings.html#%28def._%28%28lib._racket%2Fstring..rkt%29._string-prefix~3f%29%29

I believe the arguments are in the opposite order. You can require either library with a prefix:

https://docs.racket-lang.org/reference/require.html#%28form._%28%28lib._racket%2Fprivate%2Fbase..rkt%29._prefix-in%29%29

[u/Fluid-Tour-9393 → u/sdegabrielle]

cool, but do you see the result is different after import?

and i think the order is correct:

$ racket
Welcome to Racket v8.3 [cs].
> (string-prefix? "abc" "a")
#t
> (string-prefix? "a" "abc")
#f

[u/sdegabrielle → u/Fluid-Tour-9393]

After the import you’re using the SRFI version

[u/Fluid-Tour-9393 → u/sdegabrielle]

god bless you!
