Hi everybody,
I was just trying to implement a simple length of a list in core.logic
(basically solving the 99-problems-in-prolog). I am not able to find a way
to increment values.. Can somebody help me with this... I would like some
thing like the following to work..
(defnu lengtho [l n]
([[]
Please replace rst with ?rst ..
Sunil.

Here is my solution...
(defnu succ [n n+1]
([0 1])
([1 2])
([2 3])
([3 4])
([4 5])
([5 6])
([6 7])
([7 8])
([8 9])
([9 10]))
(defn pred [n n-1]
(succ n-1 n))
(defnu lengtho [l n]
([[] 0])
([[_ . ?rst] _] (fresh [n1]
(lengtho ?rst n1)
Hi Everyone,
I'm interested in seeing if there are enough people in Oxford, United
Kingdom to start an Oxford Clojure group. I'm willing to run the group in my
spare time, but it would be useful to see if there are people here who would
be interested in joining.
I don't know if this is the rig
Hi Sunil,
Use the non-relational goal "project" to get the value of a lvar.
The "is" operator in Prolog does similar things AFAIK.
Untested:
(defnu lengtho [l n]
([[] 0])
([[_ . rst] _] (fresh [n1]
(lengtho rst n1)
(project [n n1]
Thanks Ambrose. that fixed it .. I tried the following along the same lines
but didn't work.. can you suggest as to how I can do it?
(defn nlasto [l last-val]
(project [l last-val]
(== last-val (last l
(run* [q] (nlasto [1 2 3 4 5] q))
I do know how to do it in pure relational t
Your projecting last-val which is unbound. Once projected you have a value
not a logic var.

oh I see. I removed last-val from project and it worked fine..
Thanks,
Sunil.

If you're interested in relational arithmetic you might enjoy hacking away

Hi everyone- I've spent a couple of hours now trying to create a macro
that will work in ClojureScript and keep hitting a wall- Any pointers
would be greatly appreciated!
OK, so I'm running Ubuntu and have clojurescript installed at "~/
clojurescript". I have a clojurescript file "bar.cljs" in dir
Hi,
I use the following layout for my Clojure + ClojureScript coding:
project-directory/src/clj -- Clojure source
project-directory/src/cljs -- ClojureScript source
(I seem to recall that putting the directory with your cljs source on
the classpath causes weird problems when trying to compile, h
Just to highlight the key point: with the above setup, custom macros
defined in files under src/clj/ are available to cljs code under
src/cljs/ because src/clj/ is included on the classpath in the above
-cp command (so the cljs compiler can find them).
Sincerely,
Michał

Thanks Michal!
That worked like a charm :-)

Why not use this group directly?? I personally think separating people
in different groups will disperse people's attention only.what is
the benefit?

So it sounds like you intend for module writers to be writing Clojure,
but wan
He is talking about going to a location in the real world. I'm sure
you would be welcome at the Oxford group next time you are in Oxford.

Hi all,
I have a PostgreSQL database, which I am using via ClojureQL, and
whilst basic relational operations are going smoothly, I'm wondering
how to best tackle the "n+1 selects" issue and more generally how to
construct a graph of maps and arrays from the relational data.
As a specific example,
I finally came up with a simple example which shows the broken
exception handling behavior I described in my earlier post on this
thread.
(defn broken-catch [filename]
(try (java.io.FileReader. filename)
(catch java.io.FileNotFoundException fnfe
"FileNotFoundException caught")
19 matches
