I'm struggling with how to gzip/gunzip byte arrays from clojure. I
don't really get how clojure.java.io streams supposed to be used.
This appears to gzip a string:
(let [baos (java.io.ByteArrayOutputStream.)
gzos (java.util.zip.GZIPOutputStream. baos)]
(.write gzos (.getBytes "foo"))
(.finish gzos)
(.toByteArray baos))
and I can expand on this to gunzip the string afterwards:
(let [baos (java.io.ByteArrayOutputStream.)
gzos (java.util.zip.GZIPOutputStream. baos)]
(.write gzos (.getBytes "foo"))
(.finish gzos)
(let [gzbytes (.toByteArray baos)
bais (java.io.ByteArrayInputStream. gzbytes)
gzis (java.util.zip.GZIPInputStream. bais)]
(slurp gzis)))
But slurp builds strings. I need to do this with byte arrays. Do I
have to rewrite slurp to build a byte array? Is there any simpler way
to do this?
Zach Tellman's byte-streams library is very handy for these kinds of
conversions:
