fastest way to bring up a shell function for editing?

fastest way to bring up a shell function for editing?

[Jean-Rene David]

Say I define a short function on the command line
and then want to bring it up again for editing.
What's the fastest way to do it?

vared is neat. Is there a "funced" of some sort?

Try this:

% foo(){ echo "this is a function" }
% foo
this is a function
% vared foo()
function> echo "vared works... sort of"
% foo
vared works... sort of

If you hack something into zle to print the contents of the function
at the prompt...  maybe... 

Sorry this reply wasn't a real answer to your question! :)

Err, actually what you're doing there is defining two functions, one
called vared and one called foo, with the same body.  The function>
prompt is the usual continuation prompt.  You'd get it just the same if
the first line were:
% foo() {

Of course, in a case like this you can simply up-arrow and edit the
foo()... a few lines before.

Clint's answer is the most useful... the function zed supplied with the
shell does this.  Remember to autoload it.  Pedantically,

autoload -Uz zed
zed -f foo

Hit ^J when you're finished (or ^X^W if your terminal is weird).

I knew if I said something silly like that, that I'd end up learning
something in the end :)

I have these two aliases in use:

aliased() { vared   aliases[$1]; }
funced()  { vared functions[$1]; }

Which means you keep all your aliases and
functions in arrays?

zsh does it automatically (see the description of the zsh/parameter
module).
