Re: is org.clojure/java.jdbc part of the official clojure

emacs - how to wean me off the family of Java IDEs
Hi all, After 15 off years of using IDEs I am making the jump into Emacs. I have read http://dev.clojure.org/display/doc/Getting+Started+with+Emacs and https://github.com/technomancy/emacs-starter-kit and I am just at the point where I have stopped yelling at paredit and starting to appreciate its point. My current major stumbling block though is navigating my project. Whilst (I expect) the density and sane namespacing capabilities of Clojure to significantly reduce the number of files, that isn't true of everything. In particular, ExtJS encourages you to follow the one file per class. You don't have to but eventually you will have more than a handful of files regardless. So my questions: - is there a decent project explorer. I really miss the tree on the left, editor on the right layout - is there a decent JS and clojure autocompletion aware plugin - other than paredit, nrepl and clojure-mode (and the excellent coffee-mode for coffeescript), what other plugins should I install Thanks all.

I had been putting off using Emacs until I felt I was ready, but then came to realize that the choice to use Emacs is like the choice to have kids. If you wait until you're ready, you'll never do it. This is week 2 and it's definitely getting better, altho truth be told it wasn't nearly as bad last week as I expected it would be. Been working on the desktop with a cheat sheet constantly open on my laptop next to me. I also miss the project explorer. I'm used to working with multiple files at once, having them open in tabs, and being able to easily switch back and forth between any of them. I've definitely found that to be a bit jarring in Emacs, but trust that at some point I'll get used to the Emacs way versus trying to find a plugin to provide a project explorer. I have to remind myself that all of the files that I'm working with are there, they're just not immediately visible. M-x B will let me go thru the list of files open in buffers, even if those buffers aren't visible. It's different, but that's where the trust comes in :) The biggest issue I find with the lack of a project explorer is when I don't know what directory a particular file is in. Emacs provides great autocompletion when you're navigating to a particular file in the minibuffer, but that presumes you know exactly where the file is. I suppose there's always the option of opening a dired buffer (M-x dired) or even a shell (M-x shell). That's still not as easy or visual as a directory tree, but I think the big issue is that Emacs is really all about keeping your hands on the (proper) keys. A shell at least lets you continue to type your way around your directory structure to locate a file. A directory tree/project explorer would likely require grabbing the mouse and clicking down into various directories. It's what we're used to, yes… but it's not really, um… idiomatic Emacs :D -- Charlie Griefer http://charlie.griefer.com Give light, and the darkness will disappear of itself. -- Desiderius Erasmus -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: [ANN] Formative - render, parse, and validate web forms
Hi Bob, Thanks for sharing your use case. One possible approach to fieldsets (among others) is to have the renderer split fields on e.g. :heading and put each group into a fieldset. Another would be to create a :fieldset field type that itself contains other fields. I've created a GitHub issue for this - https://github.com/jkk/formative/issues/4 - and plan on addressing it in the near future. Separating the form buttons should be relatively easy with CSS - the default renderer spits out tons of classes for every piece of the form. You could also use :submit-label nil to turn off the submit button altogether and include your own as an :html type. There are various possibilities.

How to (easily) show the advantages of Clojure
Hi All, Something that came up last night in the blank? thread. What is a good way to show someone the advantages of Clojure.

Re: How to (easily) show the advantages of Clojure
Hi, I based a recent presentation in a local user group on the bank account example: two accounts, deposit, withdrawal, transfer. Starting with maps. Building the code. Noticing that no locks are required. Replacing maps with records w/o changes to underlying code. Easily testing pure functions. c. c. There was a lot of positive feedback. (Although I don't know how far things will get.) It was a two hours live session with many questions from the auditorium and ad hoc examples. The advantage of the bank account kata is that chances are that people know this already in other (maybe OO) languages. So they can easily compare with their experiences. (In fact the same kata was discussed for OO languages in December in our user group.) Meikel -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: emacs - how to wean me off the family of Java IDEs
emacs-live is a pretty great starting point.

Re: How to (easily) show the advantages of Clojure
How about something from the world of concurrency? It is not as easy to demonstrate, though. Many true advantages are too subtle for elevatorspeak, though. For example, people used to pitch *pmap* that way: instantly turn a sequence transformation into a multicore-saturating performance king. The reality is that there are increased constant-time-and-space costs involved and there are major issues with chunked seqs. Another similar thought is transforming an arbitrary calculation into a * future*. When I pitch Clojure, I use as much emotional arguments as rational ones, and I see many others feel the same way: the *joy of Clojure* is something many people feel. Sharing your enthusiasm works quite well in the field :) On Wednesday, January 16, 2013 4:08:41 PM UTC+1, Thomas wrote: Hi All, Something that came up last night in the blank? thread.

Re: How to (easily) show the advantages of Clojure
How about Clojure's web 1. Plain Clojure function as handler, request and response are just maps, they are printable. 2. Easy testable: handler is a function, pass a request, get the response, assert the response is wanted. 3. Easy mockable: use bindings to mock centain functions.

Re: How to (easily) show the advantages of Clojure
I have trouble finding a simple example, but I know I have written a lot of apps that have less than 200 lines of code, but if I had written them in PHP, they would have been a mess. And consider this: I worked at WineSpectator.com for awhile, and they had me writing big import scripts for the database. These projects usually started off sounding small: Can you write a quick PHP script to pull all the user subscriptions and update the user history table? and then they ballooned in scope, with more tables being added, and with more transformations of the data being added. A simple PHP script is good for a simple import of database data, but once you get to complicated transformations, which can be broken into pieces, then you need a multi-threaded app. I wrote one PHP script which took data from one table (that had 100 million rows) and had to combine it with data from 3 other tables (one of which had 70 millions rows). The PHP script took 3 days to run. At that point I made the argument to management We can not handle this with PHP scripts, we need something more sophisticated, and it needs to be multi-threaded. When they heard multi-threaded they thought of Java, but they were afraid of Java, because they felt it was verbose. Clojure is ideal for those situations: concise, small, fast, multi-threaded.

Re: emacs - how to wean me off the family of Java IDEs
Regarding the explorer, I keep several frames open (a frame is the word that Emacs uses for window -- I keep several windows open) and in one of those windows I'll keep my bookmarks (a bookmark is an alias you can use in Emacs to jump to any location in any file). But I also feel that Emacs is old. I donated to LightTable on Kickstarter and I have high hopes for it. Hopefully by the end of this year LightTable will be strong enough that I can make the switch.

Re: Error on redirect when attempting unauthorized entry to Friend route
I realize this is name space qualified:

::user
I'm actually referencing these in my core namespace, though the user
info is defined in (def fake-data ;; big map of fake data) which is in
a different name space. I am not sure how that would effect the way
Friend interprets the data.

Re: Error on redirect when attempting unauthorized entry to Friend route
Oh, I think I figured this out. I re-read this:
https://github.com/cemerick/friend/#authentication
And I see the keys here are strings:
(def users {root {:username root
:password (creds/hash-bcrypt admin_password)
:roles #{::admin}}
jane {:username jane
:password (creds/hash-bcrypt user_password)
:roles #{::user}}})
I switched to keywords when I implemented this in my own code. When I
copy and paste this map (above) into my code, and use root and
admin_password to login, it seems to work.

Thanks. I changed the routes so I now have:
(def app
(- app-routes
(friend/authenticate {:credential-fn (partial creds/bcrypt-
credential-fn (:users @interactions))
:workflows [(workflows/interactive-
form)]})
(wrap-resource public)
(wrap-session {:cookie-name discovery-session :cookie-attrs
{:max-age 1 }})
(wrap-cookies)
(wrap-keyword-params)
(wrap-nested-params)
(wrap-params)))
Then I go here with my browser:
localhost:4/login
and I copy and paste the username and password from the :users map
inside of @interactions. Then I hit the submit button. I get
redirected back to the login page. The URL is now:
http://localhost:4/login?login_failed=Yusername=lawrence
I am trying to think of what I can change so I can see some of the
intermediate steps. How do I debug this and find out what the point of
failure is? Part of me is thinking that I could clone Friend from
github and build my own custom version of it, with debugging code
throughout it. But most of me thinks that is stupid, since it works
for others, so the problem can not be in Friend, it must be something
that I am doing.

Re: [ANN] Formative - render, parse, and validate web forms
So I went ahead and implemented the first solution I mentioned: the default renderer now groups fields into fieldsets, split by :heading and :submit fields. Each fieldset has a class that you can target with css/js. You can see the result in the demo - http://formative-demo.herokuapp.com/.

I'll have a look at this more closely over the next couple of days, but, really, the timing could not be better… you might have just tipped a project I'm working on over to Clojure :-) It looks as though you've not put any kind of 'structure' on the fields… they are 'flat'. For example, I don't see fieldsets. One of my projects has its forms in two parts, the input fields which scroll (and have fieldsets) and a second part that consists of things like the submit and cancel buttons. The second part is pulled into a sidebar and fixed on the page (doesn't scroll with the rest of the fields). These forms can be a bit long (but they are a lot more usable than you'd think), so there's also an index in the sidebar that on click moves the scrollable part to make the corresponding fields come into view. In my current project these indexed things aren't fieldsets but they could be. Alternatively, some other kind of grouping structure could be used. Or possibly just a new field type that created an index entry… I'll have a muck about and see what I can come up with.

Re: emacs - how to wean me off the family of Java IDEs
I'm starting off with 24, so not sure what was default in 23… but C-x C-f in 24 lets you fuzzy match to a particular directory, then type a file name. The minibuffer alerts you to the fact that there's no match, but you simply hit return, then return again to confirm, and the new file is created. Trouble begins when it *does* fuzzy-match your new file name :) I ran into this when working on a Ruby project, might be less of an issue with Clojure. -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: emacs - how to wean me off the family of Java IDEs
Thanks all. LightTable does look awesome and I haven't invested enough time to fully get to grips with it yet, but I am not sure it would be an upgrade for me (wow - I am really going with the flame bait today!). Coming from IntelliJ, which is a pretty fantastic general (i.e. Java, scala, clojure, Javascript) editor to Emacs (which is an even better general purpose editor) to a Clojure specific editor is a step backwards. To be explicit, I marvel at the engineering behind LightTable, my concern is it might be too focused and not general enough. On 16 January 2013 16:09, larry google groups lawrencecloj...@gmail.comwrote: Regarding the explorer, I keep several frames open (a frame is the word that Emacs uses for window -- I keep several windows open) and in one of those windows I'll keep my bookmarks (a bookmark is an alias you can use in Emacs to jump to any location in any file). But I also feel that Emacs is old. I donated to LightTable on Kickstarter and I have high hopes for it. Hopefully by the end of this year LightTable will be strong enough that I can make the switch.

For example, I don't see fieldsets. One of my projects has its forms in two parts, the input fields which scroll (and have fieldsets) and a second part that consists of things like the submit and cancel buttons. The second part is pulled into a sidebar and fixed on the page (doesn't scroll with the rest of the fields). These forms can be a bit long (but they are a lot more usable than you'd think), so there's also an index in the sidebar that on click moves the scrollable part to make the corresponding fields come into view. In my current project these indexed things aren't fieldsets but they could be. Alternatively, some other kind of grouping structure could be used. Or possibly just a new field type that created an index entry… I'll have a muck about and see what I can come up with.

Re: Error on redirect when attempting unauthorized entry to Friend route
I am ignorant about the implications of using :: to namespace vars.
The fact that I have ::admin in one namespace:
:users {root{:username lawrence
:password (creds/hash-bcrypt admin_password)
:roles #{::admin}
:created_at 2013-01-08 14:00:00
:telephone-numbers [{:country USA :number 434 825
7694}
{:country USA :number 732 364
3640}]}
jane {:username jane
:password (creds/hash-bcrypt user_password)
:roles #{::user}
:created_at 2013-01-10 16:40:34
:telephone-numbers []}}
but then in the core name space I have:
(derive ::admin ::user)
and:
(GET /account request (friend/authorize #{::user} {} (account
request)))
(GET /admin request (friend/authorize #{::admin} {} (admin
request)))
I assume I need to change this. What are the implications? These
declarations of roles all need to reference the same namespace, yes?

Then I go here with my browser:

and I copy and paste the username and password from the :users map
inside of @interactions. Then I hit the submit button. I get
redirected back to the login page. The URL is now:
http://localhost:4/login?login_failed=Yusername=lawrence
I am trying to think of what I can change so I can see some of the
intermediate steps. How do I debug this and find out what the point of
failure is? Part of me is thinking that I could clone Friend from
github and build my own custom version of it, with debugging code
throughout it. But most of me thinks that is stupid, since it works
for others, so the problem can not be in Friend, it must be something
that I am doing.

Is keyword-params middleware safe?
From what I have read about keywords in Clojure, it does not seem like they are garbage collected. The keyword params middleware seems to convert user input into keywords. Putting two and two together, it seems like you could DoS any server using this middleware by sending large amounts of random strings as params. Eventually exhausting the memory of the JVM. This is a common security vulnerability in the Ruby world with converting user input strings to symbols. Am I missing something here?

Thanks for the confirmation.

resolving a var when AOT-ed returns nil?
Hi everyone,
Does anyone have a clue why this would perfectly run on the repl but
will throw NPE when run from the jar or via lein2 run (aot-ed)?
;;there exist global vars of the form 'xxx-NER-tags'
;;first the repl everything works as expected...I get the map back
PAnnotator.core= (var-get (resolve (symbol (str (:for-lib opts) -tags
{:middle , :closing END, :opening START:, :order [:entity
:token]}
Where (:for-lib opts) returns custom-NER ...
Now when this is aot-ed and run either via the cmd or the jar it fails
with NPE at var-get which is called with nil! For some reason resolving
a symbol brings back nil and then of course (var-get nil) will throw...
any ideas...It's been 2 hours since I did anything useful due to this...
btw I am on Clojure 1.5-RC1...
as always, thanks a lot...
Jim

I don't suppose you've thought much about this situation: I've got a couple of standard (what I'll call) mixin-forms that have fields and validations that I 'mixin' to a form (once or not at all). They aren't forms on their own, just a bunch of fields and validation rules. For example, I have a standard way of describing an entity (name, title, abbreviated description, full description, and a few other things). It's possible to think of tabs this way as well. Dropdowns in a nav bar is similar too, maybe. It's pretty clear how to get started on implementing something like this, but I'm wondering if you've considered anything in this regard. I've also got groups of several controls that operate together. The bootstrap prepended and appended inputs are simple examples. These are to some degree like the 'mixin' things I mentioned, but there can be more than one of them and they need to be distinguished, and the validation might be different for each or need to be extended for each instance. It looks to be easy enough to do this by adding new field types (extending the render-field and parse-input multimethods). Is that how you'd approach the problem? While I think of it, do you provide a way to validate that a value corresponds to one of the :options?

Re: emacs - how to wean me off the family of Java IDEs
- is there a decent project explorer. I really miss the tree on the left, editor on the right layout Emacs is my favorite editor. But it is not perfect. My thoughts from my 8 years of using it are: 1. It is very customizable, as it builds on Elisp. After you learned some Elisp programming (should not be a problem if you are doing Clojure), you can almost customize anything, either by setting config variables, adding advices (which can also replace the whole stock function with your own), or writing your own function/packages. The fact that you can easily see the source code and debug it (with edebug), make it easy to understand what is going on and the customization. Everybody can has his own Emacs. 2. The point 1 is also a disadvantage sometimes, because Emacs sometimes requires you to do a lot of customization. Sometimes it is because the package itself is low-quality, sometimes it is because you already have some heavy customization so when a new package is integrated into your Emacs, you need to customize it to fit your own already customized Emacs environment. 3. At this point, because my Emacs is so heavily customized, I can not even use a standard Emacs without my own customization. Because my heavy investment on it, even though I feel quite happy with my Emacs, I also feel like I am somehow trapped into it. Maybe not be a bad thing to be trapped with a good editor, just a reminder what may happen down the road. 4. Emacs is far from being perfect. Project management is a pretty weak spot. I use a combination of Emacs and other tools for my daily work. My thinking is: if you can make 80% of your work time more efficient (which in my case is editing code) by using Emacs, then overall you are more efficient even though you do need spend 20% time on other tools. If you go with an IDE with a lousy editor, you may need to reverse the 80% and 20% time and hence lose overall. -- You received this message because you are subscribed to the Google Groups Clojure group.

;;first the repl everything works as expected...I get the map back
PAnnotator.core= (var-get (resolve (symbol (str (:for-lib opts)
-tags
{:middle , :closing END, :opening START:, :order [:entity
:token]}
Where (:for-lib opts) returns custom-NER ...
Now when this is aot-ed and run either via the cmd or the jar it fails
with NPE at var-get which is called with nil! For some reason resolving a
symbol brings back nil and then of course (var-get nil) will throw...
any ideas...It's been 2 hours since I did anything useful due to this...
btw I am on Clojure 1.5-RC1...
as always, thanks a lot...

Re: emacs - how to wean me off the family of Java IDEs
ECB is another option.

[core.logic] Performance question
Hi I have been able to improve the performance of the core.logic based type inference in symbol quite a lot based on David's suggestions https://github.com/timowest/symbol/blob/master/src/symbol/types.clj The biggest change was to use maps for the type environment I wonder if it is possible to optimize / customize how the final map is generated defn new-env [env form] (first (run 1 [q] (fresh [type] (typedo env form type q) q will be a map in this case.

(derive ::admin ::user)
and:
(GET /account request (friend/authorize #{::user} {} (account
request)))
(GET /admin request (friend/authorize #{::admin} {} (admin
request)))
I assume I need to change this. What are the implications? These
declarations of roles all need to reference the same namespace, yes?
::foo is unrelated to vars; that's just a keyword that happens to have a
namespace component of *ns*. If you use `::foo` in namespace A, that is
namespaced as `:A/foo`, whereas the same `::foo` in B is equivalent to
`:B/foo`. For further understanding, I suggest taking a look at
http://clojure.org/multimethods, or the hierarchy/multimethod/namespaced
keyword section of your local Clojure book.
The roles you use don't all have to be identically namespaced; that would
defeat the point of using hierarchies to model relationships among independent
sets of roles. However, if you want to refer to a given namespace's ::user,
then you do need to refer to it that way, e.g. :ns-alias/user or
:full.ns.name/user.

Re: [core.logic] Performance question
Ok. But at that point can't you just process the type environment with
Clojure code? Or would you like those fresh vars to reify differently, as
in you want something other than _N?

Re: Is keyword-params middleware safe?
Keywords are garbage-collected if no references to them exist. I think this is as of Clojure 1.3, but I'm not sure exactly; perhaps it's always been true. You can see it easily enough at https://github.com/clojure/clojure/blob/master/src/jvm/clojure/lang/Keyword.java#L32 - there's a map from symbols to *references* to keywords, not keywords themselves. Those (weak) references make the keywords themselves eligible for GC. On Wednesday, January 16, 2013 9:51:59 AM UTC-8, Tony Pitluga wrote: From what I have read about keywords in Clojure, it does not seem like they are garbage collected. The keyword params middleware seems to convert user input into keywords. Putting two and two together, it seems like you could DoS any server using this middleware by sending large amounts of random strings as params. Eventually exhausting the memory of the JVM. This is a common security vulnerability in the Ruby world with converting user input strings to symbols. Am I missing something here?

Re: [core.logic] Performance question
You can prevent logic var reification by binding *reify-vars* to false. run
is lazy so you need to wrap your run in a doall as well.

This is what I was asking. You want them reify differently. In this case
you want the lvars left alone and not converted into symbols right?
Yes, you are right. At least I want to try what the performance impact

Re: [ANN] Formative - render, parse, and validate web forms
Bob, 1) Because form specifications are data, it's pretty easy to build one up at runtime. One tool for mixins -- which I just noticed isn't documented in the readme -- is *formative.core/merge-fields*. It makes it easy to tweaks fields, or insert new fields before or after existing fields. 2) Your approach sounds reasonable. Note that you can create your own :type with render-field and still use an existing :datatype; you don't necessarily have to implement parse-input. If the prepending/appending Bootstrap stuff is generalizable, it might be worth adding it to the default renderer. I don't actually use Bootstrap much myself so I'm open to improvements. 3) Right now only by using the :in validator. I've added an issue for that - https://github.com/jkk/formative/issues/6 Let me know how it goes. Feel free to add issues if you find any.

Each fieldset has a class that you can target with css/js. You can see the result in the demo - http://formative-demo.herokuapp.com/. Heh, that was quick :-) Thanks! I don't suppose you've thought much about this situation: I've got a couple of standard (what I'll call) mixin-forms that have fields and validations that I 'mixin' to a form (once or not at all). They aren't forms on their own, just a bunch of fields and validation rules. For example, I have a standard way of describing an entity (name, title, abbreviated description, full description, and a few other things). It's possible to think of tabs this way as well. Dropdowns in a nav bar is similar too, maybe. It's pretty clear how to get started on implementing something like this, but I'm wondering if you've considered anything in this regard. I've also got groups of several controls that operate together. The bootstrap prepended and appended inputs are simple examples. These are to some degree like the 'mixin' things I mentioned, but there can be more than one of them and they need to be distinguished, and the validation might be different for each or need to be extended for each instance. It looks to be easy enough to do this by adding new field types (extending the render-field and parse-input multimethods). Is that how you'd approach the problem? While I think of it, do you provide a way to validate that a value corresponds to one of the :options?

I'll have a look at this more closely over the next couple of days, but, really, the timing could not be better… you might have just tipped a project I'm working on over to Clojure :-) It looks as though you've not put any kind of 'structure' on the fields… they are 'flat'. For example, I don't see fieldsets. One of my projects has its forms in two parts, the input fields which scroll (and have fieldsets) and a second part that consists of things like the submit and cancel buttons. The second part is pulled into a sidebar and fixed on the page (doesn't scroll with the rest of the fields). These forms can be a bit long (but they are a lot more usable than you'd think), so there's also an index in the sidebar that on click moves the scrollable part to make the corresponding fields come into view. In my current project these indexed things aren't fieldsets but they could be. Alternatively, some other kind of grouping structure could be used. Or possibly just a new field type that created an index entry… I'll have a muck about and see what I can come up with.

2 issues (with workarounds) running ClojureCLR in ASP.NET
(This is my first post. Please let me know if I've got the protocol wrong.)
First, I don't know that anyone else is even trying to run ClojureCLR in
ASP.NET. All I've seen is this
posthttps://groups.google.com/d/topic/clojure/np3sRVTMrS4/discussionfrom
March 2010. It looks like the recommended patch (to RT.cs) was
eventually incorporated.
But I found that two other modifications were needed to use the current
version (1.4):
(Note that these only came up when loading Clojure in ASP.NET. I had no
problems with console programs.)
1) *Can't locate assemblies in bin*. RT.load only looks for assemblies
in AppDomain.CurrentDomain.BaseDirectory. For ASP.NET applications, this
is the root of the site, and assemblies are located under bin. I did the
following in RT.cs to get around this:
@@ -3122,6 +3122,14 @@ namespace clojure.lang
bool loaded = false;
+// Look for assembly alongside this one
+if (assyInfo == null cljInfo == null) {
+Uri codeBase;
+
+if
(Uri.TryCreate(Assembly.GetExecutingAssembly().CodeBase, UriKind.Absolute,
out codeBase)
+ codeBase.IsFile)
+assyInfo =
FindFile(Path.GetDirectoryName(codeBase.LocalPath), assemblyname);
+}
+
if ((assyInfo != null
(cljInfo == null || assyInfo.LastWriteTime
cljInfo.LastWriteTime)))
Assembly location was changed in changeset 02607349 to use a non-probing
path (although the paths returned by GetFindFilePaths() wouldn't locate in
bin, either). ASP.NET includes bin in the standard probing path, but I
think you have to actually load it for that to work.
2) *Static initialization error*. After that, loading the assembly
results in the following error
System.Reflection.TargetInvocationException: Exception has been thrown by
the target of an invocation. --- System.TypeInitializationException: The
type initializer for '__Init__' threw an exception. ---
System.NullReferenceException: Object reference not set to an instance of
an object.

Without getting too deep into the
codehttp://clojure.org/patches?responseToken=172419b0a608c93e78a91b42fd5283b5,
this is apparently due to the lexical order of the static initializers. It
goes away if you move the following line in Compiler.cs to the top of the
class:
static DictionaryString, Type _duplicateTypeMap = new
Dictionarystring, Type();
Presumably, FindDuplicateType is in the call chain of a static
initializer that appears above it — at least when running in ASP.NET.
So I'm up and running now, but I'd like to help out if possible.
Thanks,
Gavin

Another thing, that I want to mention, that some work for support of Clojure in CEDET already started: - there is lein project type for EDE, that automatically recognizes lein projects, and uses lein to fetch classpath information, that can be used for name completion (after parser will be ready).
