I come primarily from a perl programming background, but am trying
to learn Clojure.
I'm looking for a clojure equivalent to the following.
Perl:
my $nestedDS = [ "foo", { hi => there, hello => ["buddy"] }, "hi"]
my $foo = $nestedDS->[0];
my $there = $nestedDS->[1]->{hi};
my $hello = $nestedDS->[1]->{hello};
my $hi = $nestedDS->[2];
print "$foo $there $buddy $hi";
I'm not sure if it exists or not, but hopefully if it doesn't it
can be created with a macro.
To clarify, I'm looking for a function/macro that makes use of a
small DSL for accessing fields within the basic Clojure data
structures.
The best I can come up with in Clojure for a DS equivalent to the
above is:
(let [nestedDS ["foo", {"hi" "there", "hello", ["buddy"]}, "hi"]
foo (nth nestedDS 0)
there (get (nth nestedDS 1) "hi")
buddy (first (get (nth nestedDS 1) "hello"))
hi (nth nestedDS 2)]
(print foo there buddy hi)
)
Its not that much longer, but if the fields were more deeply nested,
it would become a bit pretty annoying.
Does any kind of DS access macro exist? If not, how hard do you
think it would be to write?
Something like
buddy (get-it nestedDS "[1]-{hello}-[0]")
Or perhaps an even shorter syntax is possible?
