如果被字符包围，则嵌入式表达式不会被替换 [英] Embedded expressions not replaced if surrounded by characters

问题描述

在以下简化且非常基本的情况下，嵌入的表达式在用字符附加，前置或包围时不会被替换:

The embedded expressions are not replaced when appended, prepended or surrounded by characters in the following simplified and very basic scenario:

* def jobId = '0001'
* def out = 
        """
        {
            "jobId": "#(jobId)",
            "outputMetadata": {
                "fileName_OK": "#(jobId)",
                "fileName_Fail_1": "some_text_#(jobId)",
                "fileName_Fail_2": "#(jobId)-and-some-more-text",
                "fileName_Fail_3": "prepend #(jobId) and append"
            }
        }
        """
* print out

执行该方案将返回:

{
  "jobId": "0001",
  "outputMetadata": {
    "fileName_OK": "0001",
    "fileName_Fail_1": "some_text_#(jobId)",
    "fileName_Fail_2": "#(jobId)-and-some-more-text",
    "fileName_Fail_3": "prepend #(jobId) and append"
  }
}

是功能，限制还是错误?或者，我错过了什么吗?

Is it a feature, a limitation, or a bug? Or, did I miss something?

推荐答案

这是设计好的！您可以这样做:

This is as designed ! You can do this:

"fileName_Fail_2": "#(jobId + '-and-some-more-text')"

任何有效的JS表达式都可以填充到嵌入式表达式中，因此这不是一个限制.而且这仅在JSON字符串值内或整个RHS是带引号的字符串时起作用，并且使解析变得简单.希望能有所帮助！

Any valid JS expression can be stuffed into an embedded expression, so this is not a limitation. And this works only within JSON string values or when the entire RHS is a string within quotes and keeps the parsing simple. Hope that helps !
