Hakyll网站的根源是什么？ [英] What's the root of a Hakyll site?

问题描述

  ghciλ> 
我看到create函数需要一个标识符列表。 ：t创建
 create :: [Identifier]  - >规则（） - >规则（）
  

我应该使用哪种标识符来匹配网站的根目录？例如，我只想制作出现在www.example.com上，没有/ posts或/ archives或任何其他域名部分的单个html页面。

我试过几个：

  create/$ do 
 route id路由
编译$ pandocCompiler 
>> = loadAndApplyTemplatetemplates / default.htmldefaultContext 
>>> = relativizeUrls 
  

和

  create/ *$ do 
 route idRoute 
编译$ pandocCompiler 
>> = loadAndApplyTemplatetemplates / default.htmldefaultContext 
>> = relativizeUrls 
  

和

  create。 $ do 
 route idRoute 
 compile $ pandocCompiler 
>>> = loadAndApplyTemplatetemplates / default.htmldefaultContext 
>> = relativizeUrls 
  

和

  create。 /$ do 
 route idRoute 
 compile $ pandocCompiler 
>> = loadAndApplyTemplatetemplates / default.htmldefaultContext 
>> = relativizeUrls 
  

和

 创建/。 $ do 
 route idRoute 
 compile $ pandocCompiler 
>>> = loadAndApplyTemplatetemplates / default.htmldefaultContext 
>> = relativizeUrls 
  

和

 创建 $ do 
 route idRoute 
 compile $ pandocCompiler 
>>> = loadAndApplyTemplatetemplates / default.htmldefaultContext 
>> = relativizeUrls 
  

和

  create Nothing $ do 
 route idRoute 
 compile $ pandocCompiler 
>> = loadAndApplyTemplatetemplates / default.htmldefaultContext 
>> = relativizeUrls 
  
 
 
 
我得到如下错误：
 
 
  site.hs：24：12：error：
•无法匹配类型'标识符'与字符''''
产生的'Char'
•在第一个参数'创造'，即'''
在表达式中：create
在'do'块的标记中：
 create
 $ do {route idRoute; 
编译
 $ pandocCompiler 
>> = loadAndApplyTemplatetemplates / default.htmldefaultContext 
>> = relativizeUrls} 
失败，模块加载：无。 
从/ tmp / ghci29841 / ghci-script加载的GHCi配置
  
我不能说：我标识符或阅读文档或阅读源代码对我来说这更清楚：
  ghciλ> ：i标识符
数据标识符
 = Hakyll.Core.Identifier.Identifier {identifierVersion :: Maybe 
 String，
 Hakyll.Core.Identifier.identifierPath :: String} 
  - 在'Hakyll.Core.Identifier'中定义
实例Eq标识符 - 在'Hakyll.Core.Identifier'中定义
实例Ord标识符 - 在'Hakyll.Core.Identifier'中定义
 instance显示标识符 - 在'Hakyll.Core.Identifier'中定义
  
我应该使用什么魔法咒语用来创建出现/的html，我应该如何更好地调查这个问题才能让它更加神秘？
       create 函数需要列表标识符。对于单个元素的情况，只需用括号括起来（ [] ）。并且标识符是 IsString 类的成员，所以假设您已经启用了 -XOverloadedStrings 你可以用一个普通的带引号的字符串文字（index.html）来构建一个。
 
 
 <所以要创建一个在根目录下提供的文件，你需要写： 
 
 
  create [index.html] $ do 
 route idRoute 
 compile $ pandocCompiler 
>> = loadAndApplyTemplatetemplates / default.htmldefaultContext 
>> = relativizeUrls 
  
 
 
 
 
 
 
当没有显式文件名时请求路径时提醒（例如 http://www.example.com/ ）返回文件 index.html 的内容（除非服务器配置在某些其他方式，但这是标准。）
 
I see the create function takes a list of Identifiers.
ghci    λ> :t create
create :: [Identifier] -> Rules () -> Rules ()
What list of identifier should I use to match the root of the site?  Eg, I just want to make a single html page that appears on "www.example.com" without "/posts" or "/archives" or any other domain parts.

I've tried a few:
create "/" $ do
    route   idRoute
    compile $ pandocCompiler
        >>= loadAndApplyTemplate "templates/default.html" defaultContext
        >>= relativizeUrls
and
create "/*" $ do
    route   idRoute
    compile $ pandocCompiler
        >>= loadAndApplyTemplate "templates/default.html" defaultContext
        >>= relativizeUrls
and
create "." $ do
    route   idRoute
    compile $ pandocCompiler
        >>= loadAndApplyTemplate "templates/default.html" defaultContext
        >>= relativizeUrls
and
create "./" $ do
    route   idRoute
    compile $ pandocCompiler
        >>= loadAndApplyTemplate "templates/default.html" defaultContext
        >>= relativizeUrls
and
create "/." $ do
    route   idRoute
    compile $ pandocCompiler
        >>= loadAndApplyTemplate "templates/default.html" defaultContext
        >>= relativizeUrls
and
create "" $ do
    route   idRoute
    compile $ pandocCompiler
        >>= loadAndApplyTemplate "templates/default.html" defaultContext
        >>= relativizeUrls
and
create Nothing $ do
    route   idRoute
    compile $ pandocCompiler
        >>= loadAndApplyTemplate "templates/default.html" defaultContext
        >>= relativizeUrls
I get errors like:
site.hs:24:12: error:
    • Couldn't match type ‘Identifier’ with ‘Char’
        arising from the literal ‘""’
    • In the first argument of ‘create’, namely ‘""’
      In the expression: create ""
      In a stmt of a 'do' block:
        create ""
        $ do { route idRoute;
               compile
               $ pandocCompiler
                 >>= loadAndApplyTemplate "templates/default.html" defaultContext
                 >>= relativizeUrls }
Failed, modules loaded: none.
Loaded GHCi configuration from /tmp/ghci29841/ghci-script
I can't say :i Identifier or reading documentation or reading the source code makes this any clearer for me:
ghci    λ> :i Identifier
data Identifier
  = Hakyll.Core.Identifier.Identifier {identifierVersion :: Maybe
                                                              String,
                                       Hakyll.Core.Identifier.identifierPath :: String}
    -- Defined in ‘Hakyll.Core.Identifier’
instance Eq Identifier -- Defined in ‘Hakyll.Core.Identifier’
instance Ord Identifier -- Defined in ‘Hakyll.Core.Identifier’
instance Show Identifier -- Defined in ‘Hakyll.Core.Identifier’
What magic incantation should I use to create html that will appear "/", and how should I have investigated this better to make it less mysterious?
解决方案
The create function requires a list of Identifiers.  For the case of a single element, just surround it with brackets ([]). And Identifier is a member of the IsString class so assuming you have enabled -XOverloadedStrings you can build one with just a regular quoted string literal ("index.html").

So to create a file that is served at the root you would write:
create ["index.html"] $ do
route   idRoute
compile $ pandocCompiler
    >>= loadAndApplyTemplate "templates/default.html" defaultContext
    >>= relativizeUrls




Reminder when a path is requested without an explicit file name (e.g. http://www.example.com/) the contents of the file index.html are returned (Unless the server is configured in some other way, but this is the standard.)
