GitHub MarkDown：宏和变量是可能的吗？ [英] GitHub MarkDown: Are Macros and Variables possible?

问题描述

我一直在学习github降价，我有一个关于变量和宏的问题。

可以定义一个变量或宏以防止重复打印文本块？

用例是我有一个表格产生一个超链接的大网格 - 链接如下所示。

  http：//www.a-big-long-big-big-long-hyperlink/more-long-stuff？ id = 1234 
  

如果我可以像下面这样做一次，那会很好：

  $ link = http：//www.a-big-long-big-big-long-hyperlink/more-long-stuff？id 
  

然后在表格中的每个单元格中，我可以说类似于

  $ link = 1234 
  

其他单元

  $ link = 2345 
  

这个想法是：

• 表格（有10列和10行）在正常屏幕上看起来更容易一点，此时链接的前缀太长了，链接换到下一行看起来真的很难看。


• 如果我想要改变根链接，我可以在一个地方改变它（是的，我知道我可以在编辑器中进行搜索和替换！）

干杯。

解决方案

以下是编写Reference-Links的几种方法：

 [我是内联式链接]（https://www.somewebsite.com）
 
 [我是一个带标题的内联式链接] （https://www.somewebsite.comsomewebsite's Homepage）
 
 [我是参考风格的链接] [任意区分大小写的参考文本] 
 
 [我是一个存储库文件的相对引用]（../ blob / master / LICENSE）
 
 [您可以使用数字作为引用样式的链接定义] [1] 
 
或者将其保留为空，并使用[链接文本本身] 
 
某些文本显示引用链接可以稍后进行。 
 
 [不区分大小写的任意参考文本]：https：//www.somewebsite.org 
 [1]：http://somewebsite.org 
 [link text本身] ：http://www.somewebsite.com 
  

I've been learning github markdown, I had a question about variables and macros.

is it possible to define a variable or macro to prevent repeated printing of a block of text?

The use case is that I have a table producing a big grid of hyperlinks - the links look like the below.

http://www.a-big-long-big-big-long-hyperlink/more-long-stuff?id=1234

it would be nice if I could do something like the below once:

$link=http://www.a-big-long-big-big-long-hyperlink/more-long-stuff?id

and then in each cell in the table, I can say something like

$link=1234

Some other cell

$link=2345

the idea being that:

• The table (which has ~10 columns and ~10 rows) is a bit easier to see on a normal screen, at the moment with the prefix to the links being so long, it looks really ugly as the links wrap to the next line
• If I want to change the root link, I can change it in one place (yes, I know I could do search and replace in an editor!)

Cheers.

解决方案

Below are a few ways to write Reference-Links

[I'm an inline-style link](https://www.somewebsite.com)

[I'm an inline-style link with title](https://www.somewebsite.com "somewebsite's Homepage")

[I'm a reference-style link][Arbitrary case-insensitive reference text]

[I'm a relative reference to a repository file](../blob/master/LICENSE)

[You can use numbers for reference-style link definitions][1]

Or leave it empty and use the [link text itself]

Some text to show that the reference links can follow later.

[arbitrary case-insensitive reference text]: https://www.somewebsite.org
[1]: http://somewebsite.org
[link text itself]: http://www.somewebsite.com
