Obtuse, maybe, then again many people say the same of Lisps (and pretty much
any Functional language, and APL...). it depends on the objectives of the
author and familiarity of the reader.
IMHO The Forth sweet spot has always been near or on the metal; it has an
extremely small footprint in those
Liking it so far. Can you get jline style functionality into the REPL, I
really miss it.

Hi David,
I think part of the problem is that you missed the name space from the data

You probably don't want to be doing this. Your function looks like it could
use a lazy sequency and a filter.
e.g. (doseq [e (filter odd? [1 2 3 4 5 6 7])] (prn e))
You can get a long way with partition, for, filter and reduce; It is a pain
to get your head around it at first if your are not us

If so, can anyone play?
If not, would anyone be interested?

I think you have to decide what you are aiming for. Is this a "solution" or
another tool in the toolkit. I think Rich noted a while back that Clojure

now you can wrap one of those up and off you go.

I used a couple of watchers to push model updates onto the EDT in a Swing
app; it 'just worked'. I haven't pushed the envelope on it but the
abstraction is clear and clean IMHO.

Sadly, it would not install for me. I am running 3.4.1 and I do Java dev so

Hi Mark,
I don't think this approach works in Clojure / Swing, but I may be
mistaken, I often am.
The issue is the event thread. In Abhishek's original and it's derivatives
the Swing event thread is used and the timer pushes events into it so key
press events and the game timer run in the same
Honestly? The second one, but I did say I didn't like the 'big let' style,
maybe that is why.

Hi Mark,
I think the def inside a defn has to go, it looks like an accident in
waiting.
I think you are replacing globals with a "god" structure (game) which passed
to every function, I think you need to abstract more.
I'm afraid I don't like the "big let" style and I found it hard to follow

Hi,
How do I read and print a text file? I can read it, its the printing that
is the problem, I feel it should be obvious but I keep tripping myself up.
(The context is I need to extract data line by line, translate the line
format and save it for a legacy app)
Thanks

What is interesting to me (and as it should be, I guess) is that as the code
gets more 'functional', it gets easier to work with, which is nice.

Hi Stuart,
There is a bug in end-game? which means it never ends. I'm not sure if this
is the most idiomatic way to fix it but it seems to work.

Hi,
I hope you don't mind, rather than comment on the code I made some changes
(many lifted from Abhishek and Mark's implementation):
add-points only creates one point and it doesn't move anything so name
should change, suggest new-point (maybe new-head as it is always used by the
snake?)
def
I tidied up a couple of things:
Changed function name 'verify-direction' to 'new-direction' (it is more than
a simple verification)
Passed 'direction' and 'snake-head' to 'new-direction' to avoid accessing
global state from inside the function
Used destructuring to simplify let statement in new-hea
Also; I think the 'get' is necessary on the get-snake-head and
get-snake-body.

That def inside a function doesn't look right but I'm a noob at this too. I
managed to run the snake off the board which suggests the concurrency is not
quite right.
I would use 'cell' instead of 'grid'.

Redundant comments are... redundant (hence the name), and a support overhead

cod
