Minimum Viable Database Component

Hi All, I'm trying to follow the "component" architecture for an app I'm working on and wondered if I was missing something. In the "Just enough structure" talk, one of the examples Stuart presents is a DB component that contains just a small selection of DB related functions (i.e. insert, and

Re: complex numbers in clojure

Yes, it would be nice to have this available for cljs as well. With the new reader literals though, this doesn't preclude having a native java implementation that gets loaded in the :clj case, and some other implementation that gets loaded in the :cljs case. On Wednesday, April 29, 2015 at 2:06

Re: complex numbers in clojure

Let me first say I would definitely like to see complex arithmetic support in Clojure. Major hole for scientific computing in my opinion. And with the momentum that Clojure has in ML / data science, I think it's one that needs patching. As to you specific point Nik: > For me, having complex nu

Re: wondering the reasons to choose defrecord vs reify in stuartsierra/component

Hi Juan, Components are records in order to support the dependency-injection features of `component/start-system`, which work via `assoc`. There are potentially many other ways to do dependency injection, but I found `assoc` to be practical. If you want to create a component that has a Lifecyc

Re: wondering the reasons to choose defrecord vs reify in stuartsierra/component

Often because components contain some form of data. For instance, a component that handles database connection may have a database connection instance. Reify produces objects that are essentially opaque, which is fine if you just want their behaviour, as in the case of Om, but not so good if you a

wondering the reasons to choose defrecord vs reify in stuartsierra/component

Hi guys, I'm just wondering the pros/contras that justify to choose defrecord vs reify as component fn constructor. in the component README we can read "To create a component, define a Clojure record that implements the Lifecycle protocol." Yes I know that "defrecord creates an immutable pers

Re: complex numbers in clojure

For me, having complex numbers not work seamlessly with other numbers and core arithmetic ops is not viable. Doing arithmetic ops with any kind of number is a real (pardon the pun) use case. If complex numbers are not likely to be supported fully, then maybe it makes sense to have complex numb

Re: complex numbers in clojure

Hi Before we try to guess what Rich will or won't think or want, are you interested in a proof of concept? So we could evaluate performance and complexity issues before the subject is definitively buried. What do you think about it? Plínio On Wed, Apr 29, 2015 at 12:56 AM, Mikera wrote: > You

Thanks for checking into it. Using current master seems to fix it for me as well. I'll use a local copy until the next release. Thanks again! chap On Tuesday, April 28, 2015 at 8:44:59 PM UTC-4, Alex Miller wrote: > > I think this is a bug in the fairly old tools.analyzer version used in the >

Re: How do we use a container class with a proxy?

Hi Elric, Since Clojure is untyped, you can just totally ignore the type parameter: (proxy [FooInitializer] [] (method [...])) Methods which accept or return F in the Java class will accept or return Object in Java, which is what happens under the hood anyway - type erasure means the type para
