I've a new patch for the macro language (yet another). You can find it here:
http://ajbj.free.fr/nedit/nedit5.5dev/patches/MultipleAssignment.diff
I didn't patch the help file yet, but here's the jist (taken from the patch
file):
Assign multiple lvalues in one statement
This patch allows you to assign a set of variables in a lvalue list from
the content of an array. This has the appearance of a tuple. The keys used to
retrieve the values from the array expression on the right are numeric values
starting with 1. If a key is missing, your macro will fail.
Given the following (implemented as new built-in functions in this patch):
define args {
return $args
}
define n_args {
i = 0;
while (i in $1)
++i
return i
}
You can assign a list of symbols to the content of such an array using a
list assign, thus:
(x, y, z) = args(a, b, c)
This is equivalent to
x = a
y = b
z = c
This technique can be useful for retrieving argument values in your
functions:
(str, regex, count) = $args
or for returning "tuples" from them:
define myfunc {
...
return args(isOk, message)
}
...
(success, msg) = myfunc()
If you need to count the number of variables that can be assigned in this way,
use the n_args() function:
...
result = myfunc() # we expect result is an array
if (n_args(result) >= 2)
(success, msg) = result
====
I forgot to mention you can also assign to array members, eg
(a, b, c["hello","there"]) = ("forA", "forB", "forC")
