如何用于IntelliJ Live模板内部? [英] How to use for inside IntelliJ Live Template?

问题描述

我正在尝试编写一个连接字符串的简单Groovy脚本.该Groovy脚本旨在用作IntelliJ Live模板中的变量并生成一些代码.

I am trying to write a simple Groovy script which concatenates strings. This Groovy script is intended to be used as a variable inside an IntelliJ Live Template and generate some code.

当我将 $ variableResolvedWithGroovyScript $ 设置为以下值时:

When I set the $variableResolvedWithGroovyScript$ to have the following value:

groovyScript("def elements=[\"firstElem\",\"secondElem\",\"thirdElem\"];  
          String result=\"\";  
          for (String element : elements) {      
              result=result+element;        
          }        
          return result;"
, clipboard())

我遇到以下错误:

startup failed:
Script1.groovy: 1: expecting EOF, found 'return' @ line 1, column 183.
   lt+element;         }         return res
                             ^

1 error

但是，如果我尝试删除括号( { 和 } )，则无需任何操作问题:

However, if I try and remove the for braces({ and }) it works without any problems:

groovyScript("def elements=[\"firstElem\",\"secondElem\",\"thirdElem\"];  
          String result=\"\";  
          for (String element : elements)      
              result=result+element;
          return result;"
, clipboard())

如果我使用上述脚本并在Groovy Console中运行它，则可以正常工作，因此我认为这是Live Template问题.我试图以与引号转义的方式相同的方式来使花括号转义，但是没有任何运气.

If I take above script and run it inside a Groovy Console it works without problems, so I assume this is a Live Template issue. I tried to escape the braces in the same way the quotation marks are escaped, but without any luck.

如何在实时模板中编写for(包含多个指令)?

How can I write a for(containing more than one instruction) inside of a Live Template ?

推荐答案

我设法通过从磁盘加载Groovy脚本来使其工作.因此，不是 $ variableResolvedWithGroovyScript $ 的值，是:

I managed to make it work by loading the Groovy script from the disk. So instead of the $variableResolvedWithGroovyScript$'s value, which was:

groovyScript("def elements=[\"firstElem\",\"secondElem\",\"thirdElem\"];  
      String result=\"\";  
      for (String element : elements) {      
          result=result+element;        
      }        
      return result;"
, clipboard())

我只是简单地使用:

groovyScript("d:\\Some\\Path\\Concatenate.groovy" , clipboard())

d:\ Some \ Path \ Concatenate.groovy使用花括号，我还可以定义新方法，等等.

The d:\Some\Path\Concatenate.groovy worked with braces and I was also able to define new methods and so on.
