循环遍历awk中的匹配值 [英] Looping through matched values in awk

问题描述

我正在尝试使用bash解析输入文件，并将值从'variable'提取为'}'，但是我不确定如何遍历每个匹配的值并生成预期的输出.任何帮助表示赞赏.

I am trying to parse the input file using bash and extract values from 'variable' to '}' , however I am not sure how to loop over each matched value and generate the expected output. any help is appreciated.

test.sh:

 #!/usr/bin/env bash
        
 file="./test.tf"
 output="$(awk '/variable/,/}/'  $file)"
 echo "$output

test.tf:

 variable "policy_name1" {
      description = "abc xyz"
      type        = string
      default = [
        test1,
        test2,
      ]
    }
    
    variable "policy_name2" {
      description = "aaa xyz"
      type        = bool
      default     = false
    }

预期输出:

"policyname1","abc xyz","test1,test2"
"policy_name2","aaa xyz","false"

推荐答案

Terraform输入文件遵循HCL配置语言形式(请参见

Terraform input files follow the HCL configuration language form (see https://github.com/hashicorp/hcl/blob/hcl2/hclsyntax/spec.md).

该语言支持块，条件等.使用面向行的awk脚本无法正确解析这些文件.通过使用"terraform show -json"输出，您可能会获得更多收益.或者，尝试使用export TF_LOG=trace设置env var TF_LOG，然后查看输出

The language has support for blocks, conditional, etc. It is not possible to parse those files correctly using the line-oriented awk script. You might get more mileage by using the 'terraform show -json' output. Alternatively, trying setting the env var TF_LOG with export TF_LOG=trace, and reviewing the output
