[9fans] xz compression?

Anyone ported the xz compressor/decompressor which
is gaining traction these days?

Have you checked the Go packages?  Something tells me you may find a
portable version there.

found this... looks interesting but not ready yet according to the description
https://github.com/uli-go/xz

the most recent suggestion of "using xz from go" was basically to call the xz
binary from the go code:

Even though at the back of my mind there is a nagging desire to
implement gccgo in a Plan 9 fashion (for OpenLDAP, if anyone cares), I
think the bccgo approach, useful as it is, should be limited to
obsolete software.  But that's philosophy, rather than pragmatism.

gccgo, not bccge, Apologies.

There is a new-ish GCC port (4.8.3) to Plan9 made by Alvaro
http://marcus.biz.tm/jail/comment?threadid=62&title=GNU+port+for+Plan9+upgraded
http://marcus.biz.tm/jail/comment?threadid=64&title=GCC+4.8.3+and+Lighttpd+in+Plan9

I mirrored one older (gcc 4.5) version at
http://plan9.bell-labs.com/sources/contrib/staal1978/gcc/

Basically it is the APE libs built with GCC. It should apparently support many
languages (it does not mention which ones). It might be possible to use to
rebuild GCC that supports go (if it is not included by default). The new
version uses another directory structure, but similar to regular APE it
basically is a sepparate environment from the typical Plan9 (probably to treat
more like linuxemu rather than as APE since GCC-compiled libraries can not be
mixed with the native system libraries).

I have personally looked at kerberos/heimdall + ldap before... do not remember
for what and then I tried building in "vanilla" APE (I think it was for
quagga). I have also had thoughts about a Tor client (needs libevent) and/or
one of the distributed DNS things. Right now no time to play however :(

Now that I saw this updated 4.8 port of GCC I am  eager to play around with it
again some time...

Have you considered MiniLZO [1]?
I think it *can* do the format, and it should be much easier to
port than xz(1) itself.

I have not done much testing of it however...
Would be cool to hear if it works for you.
