我是Clojure和Compojure web开发的新手。在我正在构建的玩具示例中,我注意到的第一个问题是HTML模板。我希望能够支持像Rails中的partials,或者Django使用的模板框架。
目前我有:
(defn index-page []
(html5
[:head
[:title "Home | Compojure Docs"]
(include-css "/css/bootstrap.min.css")
(include-css "/css/bootstrap-responsive.min.css")]
[:body
[:div {:class "container-fluid"}
[:div {:class "row-fluid"}
[:div {:class "span2 menu"}]
[:div {:class "span10 content"}
[:h1 "Compojure Docs"]
[:ul
[:li
[:a {:href "/getting-started"} "Getting Started"]]
[:li
[:a {:href "/routes-in-detail"} "Routes in Detail"]]
[:li
[:a {:href "/destructuring-syntax"} "Destructuring Syntax"]]
[:li
[:a {:href "/nesting-routes"} "Nesting Routes"]]
[:li
[:a {:href "/api-documentation"} "API Documentation"]]
[:li
[:a {:href "/paas-platforms"} "PaaS Platforms"]]
[:li
[:a {:href "/example-project"} "Example Project"]]
[:li
[:a {:href "/example-project-on-cloudbees"} "Example Project on CloudBees"]]
[:li
[:a {:href "/interactive-development-with-ring"} "Interactive Development with Ring"]]
[:li
[:a {:href "/emacs-indentation"} "Emacs Indentation"]]
[:li
[:a {:href "/sessions"} "Sessions"]]
[:li
[:a {:href "/common-problems"} "Common Problems"]]]
(include-js "/js/jquery-1.9.1.min.js")
(include-js "/js/bootstrap.min.js")]]]]))
(defn routes-in-detail []
(html5
[:head
[:title "Routes in Detail | Compojure Docs"]
(include-css "/css/style.css")]
[:body
[:h1 "Routes in Detail"]]))有没有不重复代码的好方法?我希望HEAD标签中的东西在它自己的模板文件或函数中,然后能够在我走的时候包括它。例如,我想把它包含在'routes- in -detail‘函数中。我看过Enlive,但我不确定如何将其用于Hiccup。任何关于最佳实践的想法都将不胜感激。

您可以将部分标记拉出到单独的var中:
(def head
[:head
[:title "Home | Compojure Docs"]
(include-css "/css/bootstrap.min.css")
... ])
(defn routes-in-detail []
(html5
head
[:body
... ]))如果你需要你的代码段/部分代码带参数,你可以把它变成一个函数,例如:
(defn head [title]
[:head
[:title title]
(include-css "/css/bootstrap.min.css")
... ])
(defn routes-in-detail []
(html5
(head "Routes in detail")
... ))有时,您可能希望您的“代码片段”包含多个顶级元素,而不是单个元素。在这种情况下,你可以将它们包装在一个列表中-- hiccup会将其内联展开:
(defn head-contents [title]
(list [:title title]
(include-css "/css/bootstrap.min.css")
... )))
(defn routes-in-detail []
(html5
[:head (head-contents "Routes in detail")]
[:body ... ]))一旦您意识到hiccup标记是由普通的clojure数据结构构成的,您就会发现使用函数操作/构建它是简单而灵活的。

有一个名为clabango的新模板库,它模仿了Django模板库,它可能就是您正在寻找的模板库:https://github.com/danlarkin/clabango
