Hi All,
Stout is a porter stemmer implemention using a snowball-like syntax for

(use 'stout.porter-stemmer)

Re: update xml attribute value
Thanks Allen, it works, I did not know the loc can be treated like a hash. 'loc itself isn't a map even though zip/edit makes it seem that way. Behind the scenes zip/edit calls (zip/node loc) which will return a map, at least in the case of this xml example. zip/edit then applies the function you provided (assoc-in) to this map plus any supplied args.

Re: Best/Idiomatic way of managing data that changes
Hmm, I posted replies to the previous posters but I might have sent
them directly. Apologies. Thanks everyone for the replies, in terms
of the game loop itself, it is more or less dictated by using
processing, so basically there're callbacks for mouse events and for
re-drawing the screen so that's taken care of.
In terms of the data itself, I was a bit wary of using the ID approach
instead of a big massive data structure with everything in it. I
somehow felt this was making things mutable in a way, but I am
convinced by the replies. In terms of code elegance, I overlooked how
elegant update-in can be, as opposed to assoc-in, and using a set in
conjunction with judicious structuring of the data, as Meikel and Jeff
suggested, will definitely make things far far more elegant.
Thanks for the replies, this is a great group!

I think the type of data structures you use will depend on how you
need to access the data. For a GUI it's nice to be able to lookup a
unit by ID, for example when it's clicked on, so I would probably
store all units in a map by ID, and then have a separate location to
ID map as you described. They could be together in an atom, or
separate in refs if you want more concurrency. Using immutable data
structures you just have to get used to creating new versions every
time you modify data, but using functions like update-in and assoc-in
you can probably get at your data pretty easily. Create a couple
functions to handle moving location, updating properties, etc., and
you might find that it isn't ugliness that you are hiding :-)

Hi,
I am writing a little board game in clojure, mostly to educate myself
about how to organise and implement a larger-scale program than my
usual tiny little snippets. The program has a central data structure
of units which are placed on a map. Each unit has some information
like a name, movement points left, strength, and it's current location
on a 2D hex-map. Units are implemented as maps, so a unit can look
like
{:name Fighter 1 :movement [3 12] :strength [4 4] :location [1 2]}.
I hold the units in a map from locations to the sequence of units on
that location. There is an atom that holds this map, so any change to
the data means basically creating a new map and resetting the atom.
So, when a unit moves, for example, I need to remove it from the
sequence at it's old location, and add it to the sequence in the new
location, and change it's location value and it's movement points
value. In Java, this would be pretty straightforward. But with
immutable data structures, it is quite clunky. I have thought of some
alternatives:
1. Continue doing what I already am, perhaps write some functions that
hide the ugliness and get on with it.
2. Give each unit object an ID and hold a map from location to unit
IDs and from ID to the actual unit object, but that is kinda like
making immutable objects all over again.
3. Using mutable data, like Java's lists, maps, etc. This is of
course extremely ugly and I would have to be strongly persuaded to go
down this route.
So, does anyone have any better ideas or is this type of program
always going to have some impedance with FP and immutable data?
Thanks

Re: Announcement: stockings clojure library for easy access to financial data
Not exactly. It is more a client API that exposes data from different web services in a consistent way. It takes care of all the tedious stuff: figuring out the right URL and query parameters, parsing the JSON, XML, or CSV responses, handling errors, fixing quirks (e.g. inconsistent time zones in date and time fields or stock symbols that do not allow for a stock exchange prefix); that kind of stuff. Try it out; the README.rst file is full of examples. fxt On Jun 2, 2:30 am, MohanR radhakrishnan.mo...@gmail.com wrote: Is that something like a mashup ?

another question on macros defining functions
Hi Here's another macro-noob question. (Thanks for the help on the previous question and please do let me know if stackoverflow is a more appropriate place to ask noob questions.) I'm trying to write a macro (or a function) that defines/declares specifically named functions. In (let [eff gee] (foo eff)) I want the macro foo to define/declare a function called foo-gee, not foo- eff. What should I do differently? First attempt: (defmacro foo [x] (let [name# (symbol (str foo- x))] `(defn ~name# [] ( (let [eff gee] (foo eff)) = #'user/foo-eff Second attempt: (defmacro foo [x] `(let [name# (symbol (str foo- ~x))] (defn name# [] ( (let [eff gee] (foo eff)) = #'user/name__4807__auto__ Third attempt: (defmacro foo [x] `(let [name# (symbol (str foo- ~x))] (defn ~name# [] ( (let [eff gee] (foo eff)) = First argument to def must be a Symbol [Thrown class java.lang.Exception] -- You received this message because you are subscribed to the Google Groups Clojure group.

The problem here is that macros run at compile time, but let bindings exist at run time. If you need the name to be determined at run time you will need to use eval. If you don't need the name at run time, why are you using (let [eff gee] (foo eff)) and not simply (foo gee)?

Re: another question on macros defining functions
You don't need to use eval to create a function dynamically in a macro. For an example, take a look at: https://github.com/duck1123/ciste/blob/master/src/main/clojure/ciste/sections.clj#L34 On Thu, Jun 2, 2011 at 10:34 PM, Ken Wesson kwess...@gmail.com wrote: On Thu, Jun 2, 2011 at 10:06 PM, nil ache...@gmail.com wrote: Hi Here's another macro-noob question.

Re: Help with primer on maps, lists or vectors
Atlas is a really useful way to look up information. It even shows the source !! Thanks, Mohan On Jun 1, 4:44 pm, Ambrose Bonnaire-Sergeant abonnaireserge...@gmail.com wrote: Hi Mohan, If you are exploring the Clojure landscape may I recommend Clojure Atlas. http://www.clojureatlas.com/org.clojure:clojure:1.2.0?guest=t#ds/maps The core functions provided with Clojure are grouped by concept. Just type a new subject into the search box. If you are trying to find a particular functionality, the Atlas is usually pretty helpful in pointing you in the right direction. Of course for further details feel free to post on the group as you already have done! Thanks, Ambrose -- You received this message because you are subscribed to the Google Groups Clojure group.
