Since these projects have to be named lein-template, you can actually get the full list via `lein search`, provided you don't need to search non-standard/private repositories. I bumped my :user profile's :search-page-size to 1000, and got this when I ran `lein search lein-template`: https://gis

Seesaw looks nice, but in retrospect I would use explicit maps if I had it to do all over again for exactly the reasons you mention. These days, I always use explicit maps for options. Dave On Fri, Apr 25, 2014 at 3:56 PM, Andrey Antukh wrote: > Hi! > > I have the same doubt! > > However, At t

Kwargs vs explicit parameter map for APIs?

Hi all, I'm working on an API at the moment, and I'm balancing whether to use inline keyword args which I would destructure in the functions, or whether to just pass an explicit params map as the last parameter. Comparison of the two options in case I'm not explaining myself well: Kwargs: (class/

I don't know if this is considered good Clojure, but you could define a print-method within a macro to set up the normal string representation for the partial function: (defmacro partial* [fname arg0 & args] `(let [pf# (partial ~fname ~arg0 ~@args) cpf# (class pf#)] (defmethod pr

I've confirmed this as a bug, it's a problem with functions inside the body of a go when used along with an async op inside the body of a loop. Thanks for the report, I've fixed it in master, and once we get a bit more feedback, I'll create a new release. Should be out sometime in the next few days

You might be interested in this ticket (http://dev.clojure.org/jira/browse/CLJ-1278) of which this is perhaps one special case. I don't know that I necessarily would want the equality semantics; at least in the case of impure functions the equality does not hold. On Friday, April 25, 2014 11:

The most interesting thing I've learned from this release is just how lenient old releases were in the face of erroneous code, of which I appear to have had rather a lot. :) That said, I have found at least one behavior I'm not able to understand. This works perfectly with the new core.async:

I do as Dan does. Sometimes I prefer to use defrecord instead of a regular map, e.g. when there are mutable values involved. In such a case I always define a constructor for the record instances. mimmo On 22 Apr 2014, at 12:06, Colin Yates wrote: > Thanks Dan, > > One benefit is compile tim
