Hi all 我在看 lein-ring插件源码时，发现很多 语法引用符号 ` 都用在defn里。 `(do ~(start-nrepl-expr project) ~(start-server-expr project)) (defn load-namespaces [& syms] `(require ~@(for [s syms :when s] `'~(if-let [ns (namespace s)] (symbol ns) s 我的直觉是这些最好是用在编译期的宏里。

Re: Local database recommendation?

No. We have done nothing with laziness. If your graph doesn't change much, you could probably roll your own. If it is changing often, I'm not sure laziness would be such a good thing. One way of rolling your own could be going through and getting all the ids of the elements you want and then ma

Re: Local database recommendation?

I have some additional questions about Titanium, as the documentation did not make these particular matters sufficiently clear: 1. Can query results take the form of a lazy sequence, one which will not result in an OOME if it's too large so long as the head is not held onto while it is consumed? E

There's been some discussion about how nesting should work. It should probably be part of the spec, in a flexible and non-intrusive way. Then we would consider a flat suite of tests to be just nested suite that's only a 1-level deep. The two things we want nesting for are defining fixture-like beh

I was messing around recently with creating a Builder class using gen-class and ran into the same issue since each set* method returns this. I'm pretty sure it's a chicken and egg issue: the class doesn't exist yet but you need to specify it in the gen-class ... I reworked your example a little

The license of the JavaScript generated by the ClojureScript compiler is the license of the source code that was compiled. And that license may be "my company owns it and it's proprietary and we're not licensing it to anyone else." Even the FSF does not assert a GPL over code compiled by GCC even

There are two things that I've notice about your code that could probably be the cause. In the :constructors section of :gen-class, you're refering to test-gen.Tata although it doesn't exist yet. The -pre-init function also tries to call a class that doesn't exist yet. 12.06.2013, 16:39, "Armel Esn
