Simple extended attribute support for Go

This afternoon I sat down and polished up the extended attribute library I have been working on for
a while. You can find the code and readme on github.

This has been tested on linux (should work under 5g, 6g and 8g) and darwin (tested under Snow Leopard).






A example program is provided with the source. The simplest way to compile and install it is

make -C $GOROOT/src/pkg/ clean install

This will install it to your $GOBIN directory. If you have trouble running this example, make sure there isn’t another xattr somewhere higher in your $PATH.

Before you start

All extended attributes need a file to be associated with. In this example I’m going to create an empty file in my home directory.

touch ~/testfile

Setting an attribute

% $GOBIN/xattr -w username dave ~/testfile

Listing known attributes

% $GOBIN/xattr ~/testfile

Printing attribute values

% $GOBIN/xattr -p username ~/testfile

Listing names and values

% $GOBIN/xattr -l ~/testfile
 username: dave
