node-rdiff v0.0.6

rdiff simple binding in node.js

http://linux.die.net/man/1/rdiff

pre

install librsync ~0.9.7 or >=1.0.0.

example

the sync api

// a new file contains "hello"
var a = "a.txt";

// a file contains "hello world"
var b = "b.txt";

// `a` wants to be `b`

rdiff.signatureSync (a, a + ".sig");
rdiff.deltaSync (a + ".sig", b, a + ".delta");

// the `a.patched` contains "hello world"
rdiff.patchSync (a, a + ".delta", a + ".patched");

do the same with async api

rdiff.signature(a, a + ".sig", function (err){
  rdiff.delta(a + ".sig", b, a + ".delta", function(err){
    rdiff.patch (a, a + ".delta", a + ".patched", function(err) {
      // yeah! contents of `a` should equal contents of `a.patched`
    });
  })
});

warning

it doesn't do file existence checking yet.
