I want to implement code migration where a user just will be able to call migrate(RemoteNode, Fun) and that local fun will end up on the RemoteNode. <div>Thus this needs to be generic. I cannot assume that:</div><div>1) All functions within the module are going to be used - transferring code which will not be used will result in useless bandwidth costs.</div>
<div>2) All functions required are within a single module </div><div><br></div><div>I was going to perform a static analysis of the function to be migrated and transfer only the functions it depends on. <br><br><div class="gmail_quote">

Why do you want to do this, instead of, for example, just sending
the module to the other node?<br>
<br>
<tt>{Mod, Bin, File} = code:get_object_code(Mod),<br>
rpc:call(Node, code, load_binary, [Mod, File, Bin]).</tt><br>
<br>
or alternatively use rpc:multicall(Nodes) for many nodes and doing
the same.<div><div class="h5"><br>

Hey Jesse
<div> I need something stronger than just import. I need to put
a bunch of functions from different modules into a single one
and transfer this to a remote node. Then I want to be able to
use these functions from the remote node. </div>
<div>If I simply use import, I will not be able to use them on the
remote node without explicitly transferring all the modules to
which the functions belong to.</div>

Hey all,
<div> Is there any mechanism in Erlang which I
can use to copy functions from one module to
another? So, if I have module <b>A</b> containing
functions <b>a</b>, <b>b</b> and <b>c</b>, is
there any way in which I can copy <b>a</b> to
module B?<br clear="all">

<div>Thanks </div>
