在Android的使用大块模板引擎的自定义标签 [英] Using chunk template engine in android with custom tags

问题描述

我想在Android中使用的块。我需要的是这样的：

I am trying to use chunk in android. I need something like this:

假设，

以下是标签。

标签： {世界：世界，C：丹尼斯里奇，苹果：乔布斯}

tags: {"world":"WORLD", "c": "Dennis Ritchie", "apple":"JOBS" }

输入： HELLO {{世界}}，C是写的 {{c}里} ，而Java是由{{java的}}，HOLA写

Input: HELLO {{ world }}, C is written by {{ c }}, while java is written by {{ java }}, hola.

输出： HELLO WORLD，C是由丹尼斯里奇写的，而Java写的按，HOLA

Output: HELLO WORLD, C is written by Dennis Ritchie, while java is written by, hola.

在短期

1. 我需要一个自定义分隔符一样，{{字​​符串}}
   即

1. I need a custom delimiter like, {{ string }} i.e.

DEFAULT_TAG_START ={{;

DEFAULT_TAG_START = "{{";

DEFAULT_TAG_END =}};

DEFAULT_TAG_END ="}}";

而如果输入中包含未指定标签，那么它应该被替换为空。

While if input contains tag which is not specified, then it should be replaced by empty.

我试过放＆;被困在下面，

I tried & stuck at following,

public String process(String msg) {

   Chunk c = new Chunk();               
   c.append(msg);
   c.set("apple", "JOBS");
   c.set("c", "Dennis Ritchie");
   c.set("world", "WORLD");
   return c.toString();

}

有人

可以知道该怎么办呢？

Can anybody knows how to do it?

推荐答案

块模板引擎不支持在目前备用标记语法。此外，标签标志中的空格不会被忽略/丢弃。

The Chunk template engine does not support alternate tag syntax at the moment. Also, whitespace within tag markers is not ignored/discarded.

不过，这里有一个可能的桥接解决方案。未提供该块标签将默认只要变量名后跟一个冒号空。

However, there is a possible bridge solution here. Chunk tags that are not provided will default to empty as long as the tag name is followed by a colon.

所以你的输入必须改变，以有效块语法：

So your input must change to valid Chunk syntax:

HELLO {$world:}, C is written by {$c:}, while java is written by {$java:}, hola.

如果您的模板语法是不灵活（例如，你有pre-现有模板库，或者你只是真的不喜欢原生标记语法），你可以添加一个pre-处理步骤进行改造 {{}这个} 到 {$这样的：} 才追加到块模板

If your template syntax is not flexible (eg, you have a library of pre-existing templates, or you just really dislike the native tag syntax) you could add a pre-processing step to transform {{ this }} into {$this:} before appending it to the Chunk template.

块库甚至还提供了方便的功能会为你做到这一点（虽然你可能需要重新实现它，如果输入的是空格不一致）。

The Chunk library even provides a convenience function that will do this for you (although you may need to reimplement it if the input is inconsistent with whitespace).

import com.x5.template.TemplateSet;

...

Chunk c = new Chunk();

String template = TemplateSet.convertTags(msg, "{{ ", " }}", "{$", ":}");
c.append(template);

c.set("apple", "JOBS");
c.set("c", "Dennis Ritchie");
c.set("world", "WORLD");
return c.toString();
