[jruby-dev] RubyIO 1.9, trying to work with internal encoding.

[David Calavera]

Hi,

I'm working in the issue 3943,
http://jira.codehaus.org/browse/JRUBY-3943,"[1.9] IO objects should
use internal encoding to transcode output strings"
but I think I don't understand the behavior of ByteList class.

Actually, what I'm trying to do is to change the RubyString encoding just
before to show it. I'm using the method RubyString#associateEncoding but I
think when I call ByteList.toString() it's not using the encoding set.

I've found a ByteList implementation in this repository :
    http://github.com/vvs

http://github.com/vvs/bytelist/blob/ad82ffcdc6ee19ff7d0df2b7f615a5cc97222e50/src/org/jruby/util/ByteList.java

I don't know if this is the official one and actually I don't understand why
this class isn't in the jruby repository, but taking a look to this class I
can see this code:

/**
     * Remembers toString value, which is expensive for StringBuffer.

     *
     * @return an ISO-8859-1 representation of the byte list
     */
    public String toString() {
        try {
            if (stringValue == null) stringValue = new String(bytes,
begin, realSize, "ISO-8859-1");

            return stringValue;
        } catch (UnsupportedEncodingException uee) {
            throw new RuntimeException("ISO-8859-1 encoding should
never fail; report this at www.jruby.org");

        }
    }

So, when rather than use its encoding variable ISO-8859-1 is hardocoded. Is
this the right repository and the expected behaviour? can I modify it to use
the ByteList#encoding variable?

suggestions to handle this are welcome :)

Cheers
