Re: spec key aliasing or different specs for same keyword
Yes, the namespacing is great, so I have no issue with that. I would just rather use snake-case in Clojure than camel-case. Since the payload has 'resultCount' I'd like to map that to a spec named result-count instead. I think I figured out part of the answer: (s/def :my/result int?) (s/def :your/result pos-int?) (s/def ::test-spec-1 (s/keys :req-un [:my/result])) (s/def ::test-spec-2 (s/keys :req-un [:your/result])) I see here that I can have an unqualified keyword as part of a qualified spec name. I think that's what I want.

Re: Converting json to work with clojure.spec

Protocols for persistence - not sure about a few cases
I'm beginning a foray into protocols after coming from the Common Lisp world of multimethods. I'm using them initially to implement a consistent load/save API over the DB layer. It's pretty simple to have a Saveable protocol to save one object, because the first argument is a Record of the type I am saving. But since protocols dispatch on the first argument, how do you define a Loadable protocol that loads an object or handles a collection of objects? For example, if I want to load an object by idx, the first argument is not a Record, but an integer, or perhaps an arbitrary field to used in a query. -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: Compojure character encoding
Thanks, James.
To clarify, Compojure has no problems serving the JSON content. But the
SBCL common lisp app and a third-party app (Klipfolio) both are choking on
the output. I was able to fix the SBCL app by telling Babel to use latin-1
encoding, but I need another solution for the output to Klipfolio. It's
probably a knowledge gap on my part of correct use of encodings, and I just
haven't found the 'correct' solution yet.

Yes, you can return a full response map with the desired encoding:
(GET / []
{:status 200
:headers {Content-Type text/html; charset=ISO-8859-1}
:body Hello World})
Or use the ring.util.response namespace:
(GET / []
(- (resp/response Hello World)
(resp/charset ISO-8859-1)))
Or write some middleware to change the charset globally:
(defn text-response? [response]
(some- (resp/get-header response Content-Type)
(.startsWith text/)))
(defn wrap-charset [handler charset]
(fn [request]
(let [response (handler request)]
(if (text-response? response)
(resp/charset response ISO-8859-1)
response
However, it's odd that you can't consume UTF-8 encoding. Are you sure
that's the problem?

Re: How to handle refactoring with TDD and mocking/stubbing

that is exactly the kind of problem I'm talking about! Right down to the

Could you give an example? I use mocks fairly heavily, and I don't seem
to have this problem. Perhaps it's because I change the tests before the
code?
Although the subject changed a little bit, I would be still interested
in your approach to refactoring if there is heavy use of mocking. Let me
give you an example:
Let's say I am writing a login form, trying to use the top-down approach
you described. My approach could be the following:
(unfinished check-pw)
(fact login-form succeeds if user enters the correct password
(login-form-success? {:username admin :password secret}) = true
(provided
(db/get-user admin) = (contains (:password my-secret-hash))
(check-pw my-secret-hash secret) = true))
(defn login-form-success? [user-input]
(let [user (db/get-user (:username user-input))]
(check-pw (:password user) (:password user-input
Then I finish the check-pw function and everything works.
Now, later that day I decide that I pass the whole user object to the
check-pw function. Maybe I want to use the user ID as a salt, or maybe I
just want to leave the possibility for checking password expiration,
etc. So I modify the test and the implementation of check-pw so that the
first parameter is the user object, not the password hash.
Suddenly my co-worker comes to me saying hey, I need you on a meeting
right now! I close my laptop, and an hour later I think where were
we?... I run all the tests, and they all pass, so I commit.
Except... I forgot to modify all the invocations of check-pw in both the
test and the implementation. Every test pass, so I have no way of
finding out the problem without careful code review or by examining the
stack traces from the live code.
While this bug is easy to catch, what if my function is mocked in
several places, and I fail to rewrite all of them properly?
Do you have any advice on what you would have done differently here to
avoid this bug?
Regards,
Akos

Re: core.async go-loop questions
Well, my goal is to start a go-loop (if possible) at the root level of the code that simply parks and waits for a group of emails to be sent. When that happens, it would wake up and broadcast the result of the send operation via web socket back to the browser. I'd like to avoid starting that loop every time I send the emails, and I was under the impression that could be done with a go-loop, which would park until the channel had values to consume.

If I wrap ONLY the www-routes in Friend and remove api-routes entirely, it

From https://github.com/cemerick/friend :
The example above defines a single workflow — one supporting the POSTing
of :username and :password parameters to (by default) /login — which
will discover the specified :credential-fn and use it to validate
submitted credentials.

2. Attempts to access the /locked URL throw an exception and a

Compojure routing of www and api content
I'm serving up some html and js content, and using handler/site for that.
I have a separate handler/api group of routes under the /api context.
If I include the api routes before the site routes, the site works fine.
If the www routes come first, the api calls fail, probably because the
(route/resources /) at the end of the site routes catches that call and
returns null.
OTOH, if I try to use friend with the api routes, it breaks the friend
wrapping of the www calls.

One benefit of using korma is that it uses a connection/statement pooling library underneath (in this case c3p0), something that I don't think yesql/honeysql do. -- You received this message because you are subscribed to the Google Groups Clojure group.

I liked the no-fuss integration of relationships for the particular project I'm working on. I could live without it, but it would greatly simplify the code on server side.

Database schema Heroku and Node-Webkit
I'm developing an app that will initially run on Heroku, but will eventually migrate to a Node-Webkit app. What would you suggest is the simplest way to create and maintain a schema that would work well on both a Heroku app (with PostGres) and a Node-Webkit app (perhaps Sqlite or another alternative) ? I considered using raw SQL then using Lobos analyze mode to extract a schema, then use that for multiple back ends, but that might be more work that needed.

Ring mock with GET parameters
I'm using ring.mock.request to test an API. POST parameters work fine, but
for GET requests, the parameters are not where Compojure expects to find
them.
Here is the relevant part of the handler:
(GET /outlines [speaker :as r]
(println (str Request r))
(println (str Param ' speaker '))
)
Here is the test using the mock request:
(let [req (request :get /api/outlines {:speaker Test Speaker 1})]
(is (= expected-outlines (api-routes req
Here is the value of the request and the 'speaker' parameter in the handler:
Request {:remote-addr localhost, :scheme :http, :context /api,
:request-method :get, :query-string speaker=Test+Speaker+1, :route-params
{}, :path-info /outlines, :uri /api/outlines, :server-name localhost,
:params {}, :headers {host localhost}, :server-port 80}
Param ''
The mock library apparently puts the GET params into query-string, so
Compojure does not see them. Is there a way to work around this without
changing ring.mock.request?

I'm starting on a new Clojure app, and have been really intrigued by Pedestal. But it seems to present a new conceptual model to get my head around.

I would really like something that makes the mundane CRUD tasks easier, and a responsive front end with data binding and DOM manipulation.

Re: Breaking out of doseq
To clarify what I'm trying to do, I have a map of regexes, and after iterating them, when one matches (the order of the regexes is significant) I want exactly one result returned by applying the looked up function to the string. After that regex matches, no more matches should be attempted. What is the 'reduced' function?

Re: Heroku Clojure scheduled tasks versus worker threads
You are correct, I meant to say 'worker process type' as opposed to 'web process type'. So, the question then, is what would be the difference between a heroku scheduled command (which I currently am running, wakes up, does some work, etc) and a 'worker process' type? Does the latter need a job queue set up? Does it run constantly, checking that queue and consuming work items from it?

Workers generally consume a queue. I'm not sure what you mean by worker thread though. Workers don't run in a thread, and you can launch plain old threads whenever you want to in your Clojure code.

New Relic installation on Heroku
I followed these directions to install New Relic on my Heroku app: http://www.rafael-chacon.com/post/19069499949/new-relic-clojure-heroku-easy-steps-integration I added my license key to the yml file, and restarted the app. It's a simple app, with an import run from the CLI and an export as JSON web services. I ran a few of both to trigger the New Relic agent. At least I hoped so. Though my New Relic account page located my app, it said no data was being received. I thought this was an out-of-the-box setup. Any ideas on what I can check to see what's going wrong?

That's a good suggestion. I made that change, and there definitely was a different because the heroku log said New Relic agent was already running because it had been specified in the JVM_OPTS.

Re: Test strategy
I guess the challenge is that the parsing and generating of the structures from JSON descends to several layers of functions, and the database object is created and inserted/updated at the lowest level. I've tried a bulk insert after accumulating records into a higher level function, but sometimes I need to query for an item previously inserted, so I'm back to inserting each item as created. The challenge is decoupling object creation from insertion without breaking the nested process approach.

I understand you're trying to test fns that take a map produced by the JSON parser, and extract specific fields. Would it be sufficient to just create literal maps to fake the output of the JSON parser, use those as inputs to your extraction fns, and then just compare the output to what you expected? If the issue is that the extraction isn't done by top-level fns, and thus is hard to test, perhaps you could just make them top-level fns?

I haven't seen such a function yet. -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Looping and accumulation
I have a loop over a function that is accumulating a list of database keys for later use. But it is primarily doing other processing and returning a collection of processed/filtered records. I'd normally just PUSH the ids and records onto a list in Common Lisp, or even LOOP... COLLECT into 2 lists. In the Clojure way, how would I build this auxiliary list without using a mutable collection? Would it make sense to return a map or some other structure from the processing function that would contain both the processed record as well as any id of interest? I could accumulate this result, then filter the map into 2 collections - one of processed records and the other a subset of id's of interest. But that seems kludgy commingling the results like that. -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Understanding sequences
I have 3 arrays, and need to process one element of each array as a triplet. So [1 3 5] [2 4 6] [10 20 30] needs to produce [1 2 10] [3 4 20] [5 6 30] In Common Lisp, I would just use LOOP. What's the correct Clojure way? -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Understanding sequences
Yes, both work. Sorry, I've been staring at non-working code too long tonight. ;-) On Wednesday, February 13, 2013 10:49:58 PM UTC-5, Jonathon McKitrick wrote: I have 3 arrays, and need to process one element of each array as a triplet.
