The equivalent of this in Go would be io.Reader and io.Writer and friends. Transformers in text are lower-level and allow for easier to implement, but above all, more efficient implementations of transforms. For text the latter is often quite important. Once you created a transform using Chain, you can convert it to a Reader or Writer, for instance, using transform.Reader or transform.Writer. BTW, regarding your original problem, it is often more desirable to replace non-ASCII by encoding.ASCIISub (U+001a). This is the default behavior of the charmap.Windows1252 encoder. If you want to use "?" instead, it may be better to replace U+001a with '?' instead of just replacing non-ASCII. > > > Le mardi 28 juin 2016 11:54:25 UTC+2, Tamás Gulácsi a écrit : >> >> I've used bufio.Scanner to implement a custom transforming stream reader. > > -- > You received this message because you are subscribed to the Google Groups > "golang-nuts" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to golang-nuts+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
