Is this the good way to write get-percentage

I needed a function to get the percentage as an int. Input is place and total-count. I want the normal definition (which is the default) and a high and low variant. I came up with the following code: (defn get-percentage ([place total-count] (get-percentage :normal place total-count))

That's really great! I can vouch for the stability of beta1. Been running for a small app in production, handling filtered twitter stream data. Never have looked at it since it was started some months ago (except for a VM restart once). To be fair, there's no high load on this app, but it handles

[ANN] Immutant 2.0.0-beta2

Hi all, We released Beta 2 of "The Deuce" today: http://immutant.org/news/2015/02/09/announcing-2-beta2/ We introduced some breaking changes, specifically around WebSockets, but we like the new API, as it now directly supports HTTP streams, including Server-Sent Events. See the "Asynchrony" se

Re: Extending the LispReader with "embeded language lorms"

For a competent English speaker/reader, Infinite Jest is "hard to read" because it's dense and elliptical &c. &c. For that same reader, Tintin in the original French is "hard to read" because it's in French. I think that's a relevant distinction to make in this context. Extensibility is nice, b

Re: Serving files from outside a ring uberjar

If you're using Compojure, you can use compjure.route/files for that (as opposed to compojure.route/resources which looks inside the jar). As Moritz said, you still have to be a bit wary about the file path, as it will be relative to the current directory of the JVM, not relative to the JAR file lo

Re: Extending the LispReader with "embeded language lorms"

I *think* Alex means "read" in the very specific and technical sense of a Lisp reader, i.e. a piece of program that turns a stream of characters into data structures in memory, and then I guess the other "users" are all of the other programs, beside the Clojure compiler itself, that may want to ana

Re: Extending the LispReader with "embeded language lorms"

For the sake of completeness, in this context "other users" is not limited to humans: what about IDE support? Refactoring tools? Code analysis? You have to balance the potential extra complexities with the benefit, which to me seems to be very sparse: how often do you actually need to embed large

Re: Extending the LispReader with "embeded language lorms"

Hi Henrik, There is a long-standing philosophical position in Clojure that it should not be possible to write programs that cannot be read by other users. Because of this position, I do not believe there is any chance of this moving forward in Clojure itself. Tagged literals allow creating new

Re: How to profile a clojure program?

I would think you could just use a normal profiler with some mental translations. The translations between Clojure vars/namespaces and Java classes are in most cases pretty straightforward. A function "foo" in namespace "core" becomes class "core$foo", function bar becomes "core$bar", etc. Then

Why STM read are not cached?

Serving files from outside a ring uberjar

I would like to be able to serve up files from a folder after the jar has been built. Ideally I could take a parameter in to the jar with the target directory, but I could also settle for putting the jar in the directory with the files or hardcoding a target directory near the jar. This is so t

Re: Help needed with Component library

Hi, I've been messing around with the component library too recently, It's probably worth printing out the defrecord (the Ring one) to see if the values are being populated by the start function. You could just do this in the repl using clojure/pprint.pprint. I also do (assoc this :jetty nil)

In main.clj, it looks like you aren't keeping a reference to the started app. So when you call stop, you are actually stopping the version of the system which doesn't have the jetty server set. Try changing this: (defn -main [& args] (component/start app) (component/stop app)) to this: (de

I get the same error because the key :jetty-server = nil so, (:jetty-server this) will return nil what turns into (.stop nil) note that if I print 'this' after assoc'ing :jetty-server in the start lifecycle I see the jetty server associated with the key :jetty-server for some reason I'm loosing t

What happens if you try: (.stop (:jetty-server this)) instead of: (.stop jetty-server) I'm not at a repl right now, but maybe your stop method is closing over the value of jetty-server that's passed in when the record was constructed? On 10 February 2015 at 22:58, Gilberto Garcia wrote: > He
