Let me translate: Hi all, I am reading lein-ring's source code, and I find that the many functions(defn) uses the syntax quote(`), e.g.
> (defn load-namespaces > [& syms] > `(require > ~@(for [s syms :when s] > `'~(if-let [ns (namespace s)] > (symbol ns) > s)))) My intuition is that syntax quote better be used in macros which is invoke during compiling. What's reason/benefit to use syntax quote in functions which will are invoked at runtime? -- xumingmingv Github: https://github.com/xumingming Weibo: http://weibo.com/64398966 Sent with Sparrow (http://www.sparrowmailapp.com/?sig) On 2013年6月13日Thursday at 下午12:39, stream wrote: > 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。 > > 用在运行期的的函数里是什么意思呢， 比较愚笨，希望高手解答。谢谢 > > -- > -- > You received this message because you are subscribed to the Google > Groups "Clojure" group. > To post to this group, send email to clojure@googlegroups.com > (mailto:clojure@googlegroups.com) > Note that posts from new members are moderated - please be patient with your > first post. > To unsubscribe from this group, send email to > clojure+unsubscr...@googlegroups.com > (mailto:clojure+unsubscr...@googlegroups.com) > For more options, visit this group at > http://groups.google.com/group/clojure?hl=en > --- > You received this message because you are subscribed to the Google Groups > "Clojure" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to clojure+unsubscr...@googlegroups.com > (mailto:clojure+unsubscr...@googlegroups.com). > For more options, visit https://groups.google.com/groups/opt_out. > > -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
