Jade 中的 doctype 声明

Question

我正在尝试在 Jade 中重新复制以下输出代码（包括回车），但没有成功：

尝试输出以下内容：

<?xml version="1.0"?>
<!DOCTYPE j:jelly 
[
  <!ENTITY aacute "&#x000E1;">
  <!ENTITY Aacute "&#x000C1;">
  <!ENTITY ordm "&#x000BA;">
  <!ENTITY euro "&#x020AC;">
  <!ENTITY amp  "&#x00026;">
  <!ENTITY iquest  "&#x000BF;">
  <!ENTITY iexcl  "&#x000A1;">
  <!ENTITY copy  "&#x000A9;">
]>

在玉码我有：

<?xml version="1.0"?>
doctype j:jelly[<!ENTITY aacute "&#x000E1;"><!ENTITY Aacute "&#x000C1;"><!ENTITY eacute "&#x000E9;"><!ENTITY ordm "&#x000BA;"><!ENTITY euro "&#x020AC;"><!ENTITY amp  "&#x00026;"><!ENTITY iquest  "&#x000BF;"><!ENTITY iexcl  "&#x000A1;"><!ENTITY copy  "&#x000A9;"> ]

只输出一行（工作但混乱，没有回车）：

<?xml version="1.0"?>
<!DOCTYPE j:jelly [<!ENTITY aacute "&#x000E1;"><!ENTITY Aacute "&#x000C1;"><!ENTITY ordm "&#x000BA;"><!ENTITY euro "&#x020AC;"><!ENTITY amp  "&#x00026;"><!ENTITY iquest  "&#x000BF;"><!ENTITY iexcl  "&#x000A1;"><!ENTITY copy  "&#x000A9;">]>

Answer 1

所以只需在原始文本中添加换行符：

<?xml version="1.0"?> 
| < doctype j:jelly
| [
|  <!ENTITY aacute "&#x000E1;">
|  <!ENTITY Aacute "&#x000C1;">
|  <!ENTITY eacute "&#x000E9;">
|  <!ENTITY ordm "&#x000BA;">
|  <!ENTITY euro "&#x020AC;">
|  <!ENTITY amp  "&#x00026;">
|  <!ENTITY iquest  "&#x000BF;">
|  <!ENTITY iexcl  "&#x000A1;">
|  <!ENTITY copy  "&#x000A9;">
| ]>

得到

<?xml version="1.0"?> 
< doctype j:jelly
[
 <!ENTITY aacute "&#x000E1;">
 <!ENTITY Aacute "&#x000C1;">
 <!ENTITY eacute "&#x000E9;">
 <!ENTITY ordm "&#x000BA;">
 <!ENTITY euro "&#x020AC;">
 <!ENTITY amp  "&#x00026;">
 <!ENTITY iquest  "&#x000BF;">
 <!ENTITY iexcl  "&#x000A1;">
 <!ENTITY copy  "&#x000A9;">
]>

因为这仅使用原始文本，您可以考虑使用 include 语句。

与

start.jade：

include ./other.jade

和

other.jade：

<?xml version="1.0"?> 
< doctype j:jelly
[
 <!ENTITY aacute "&#x000E1;">
 <!ENTITY Aacute "&#x000C1;">
 <!ENTITY eacute "&#x000E9;">
 <!ENTITY ordm "&#x000BA;">
 <!ENTITY euro "&#x020AC;">
 <!ENTITY amp  "&#x00026;">
 <!ENTITY iquest  "&#x000BF;">
 <!ENTITY iexcl  "&#x000A1;">
 <!ENTITY copy  "&#x000A9;">
]>

你会得到

/usr/lib/node_modules/jade/lib/runtime.js:240
  throw err;
        ^
Error: other.jade:3
    1| <?xml version="1.0"?> 
    2| < doctype j:jelly
  > 3| [
    4|  <!ENTITY aacute "&#x000E1;">
    5|  <!ENTITY Aacute "&#x000C1;">
    6|  <!ENTITY eacute "&#x000E9;">

unexpected text [

    at parse (/usr/lib/node_modules/jade/lib/index.js:104:21)

因为要包含的文件被解释为玉模板。重命名就好了。

与

start.jade：

include ./other.inc

和

other.inc：

<?xml version="1.0"?> 
< doctype j:jelly
[
 <!ENTITY aacute "&#x000E1;">
 <!ENTITY Aacute "&#x000C1;">
 <!ENTITY eacute "&#x000E9;">
 <!ENTITY ordm "&#x000BA;">
 <!ENTITY euro "&#x020AC;">
 <!ENTITY amp  "&#x00026;">
 <!ENTITY iquest  "&#x000BF;">
 <!ENTITY iexcl  "&#x000A1;">
 <!ENTITY copy  "&#x000A9;">
]>

你会得到预期的

<?xml version="1.0"?> 
< doctype j:jelly
[
 <!ENTITY aacute "&#x000E1;">
 <!ENTITY Aacute "&#x000C1;">
 <!ENTITY eacute "&#x000E9;">
 <!ENTITY ordm "&#x000BA;">
 <!ENTITY euro "&#x020AC;">
 <!ENTITY amp  "&#x00026;">
 <!ENTITY iquest  "&#x000BF;">
 <!ENTITY iexcl  "&#x000A1;">
 <!ENTITY copy  "&#x000A9;">
]>
