AWK 从结果创建内部变量数组并在 END 块中打印

Question

我有以下variables.tf 文件：

variable "ARM_CLIENT_ID" {
  description = "Client ID for Service Principal"
}

variable "ARM_CLIENT_SECRET" {
  description = "Client Secret for Service Principal"
}

variable "ARM_ENVIRONMENT" {
  description = "The deployment environment acronym to which the resources are being deployed"
}

variable "ARM_LOCATION" {
  description = "The geo location to which the resources are being deployed"
}

variable "ARM_SUBSCRIPTION_ID" {
  description = "Azure Subscription for deployment"
}

variable "ARM_TENANT_ID" {
  description = "Azure AD tenant identifier for Service Principal"
}

variable "expressroute_settings" {
  description = "(Required) ExpressRoute Gateway and Public IP settings"
}

variable "firewall_settings" {
  description = "(Required) ExpressRoute Gateway and Public IP settings"
}

variable "global_settings" {
  description = "Global settings for subscription"
}

variable "peering_settings" {
  description = "(Required) vNet Peering configuration for shared services vnets"
}

variable "vnet_transit_object" {
  description = "(Required) configuration object describing the transit networking configuration, as described in README"
}

variable "vnet_shared_services_object" {
  description = "(Required) configuration object describing the shared services networking configuration, as described in README"
}

variable "route_tables" {
  description = "Routes for subnets declared in tfvars"
}

variable "logging_settings" {
  description = "Logging settings from TFVARs"
}

variable "azure_firewall_nat_rule_collections" {
  default = {}
}

variable "azure_firewall_network_rule_collections" {
  default = {}
}

variable "azure_firewall_application_rule_collections" {
  default = {}
}

在AWK print block that does NOT contain specific text 的帮助下，我能够提出以下 AWK 程序，只要结果块中不包含单词 default，它就可以帮助我打印出结果。

BEGIN   {
    string = "route_tables,global_settings"
    regex = "[,]"
    n = split ( string, arr, regex )
}
{ gsub("\"", "") }
/^variable/     {   varname = $2
                    printme = 1
                }
                {
                    for ( i=1; i<=n; i++ )
                        if ( $2 ~ arr[i] )
                            printme = 0
                            myarr[i] = $2
                }
/variable/,/^}/ {   if ( $0 ~ "default" )
                        printme = 0
                    next
                }
printme         {   printf varname " = \"\"\n"
                    printme = 0
                }
END {
    for ( x=1; x<=n; x++ )
        print myarr[x]
}

结果如下：

ARM_CLIENT_ID = ""
ARM_CLIENT_SECRET = ""
ARM_ENVIRONMENT = ""
ARM_LOCATION = ""
ARM_SUBSCRIPTION_ID = ""
ARM_TENANT_ID = ""
expressroute_settings = ""
firewall_settings = ""
peering_settings = ""
vnet_transit_object = ""
vnet_shared_services_object = ""
logging_settings = ""

注意；最后的两个额外的空白行，这是由于我无法正常工作的新变量数组引起的。

（我知道我在上面链接中的原始问题中确实说过我不想包含ARM_，但情况仍然如此，但为了进行有效测试，我没有将其包含在我当前的 AWK 程序中)

我正在尝试扩展这个想法，以便创建一个名为myarr 的变量数组，并添加来自变量string 的值（如果它们在文件中找到）。然后在END 块中，我可以将它们打印为列表。

为什么要打印出来？所以我可以在上面附加一些文本，就像我对varname 打印所做的那样。

编辑：为了阐明我希望它如何输出，我创建了这个虚拟文本文件。我想将字符串中的值输出到 END 块（在处理完所有内容之后），希望通过变量数组（如果这是正确的做法？）

您遇到的问题是if 语句和for 循环周围缺少{ 和}：

BEGIN {
  string = "route_tables,global_settings"
  regex = "[,]"
  n = split ( string, arr, regex )
}
{ 
  gsub("\"", "")
}
/^variable/ {
  varname = $2
  printme = 1
}
{
  for ( i=1; i<=n; i++ ) {
    if ( $2 ~ arr[i] ) {
      printme = 0
      myarr[i] = $2
    }
  }
}
/variable/,/^}/ {
  if ( $0 ~ "default" )
     printme = 0
     next
}
printme {
  printf varname " = \"\"\n"
  printme = 0
}
END        {
  for ( x=1; x<=n; x++ ) {
    print myarr[x]
  }
}

ARM_CLIENT_ID = ""
ARM_CLIENT_SECRET = ""
ARM_ENVIRONMENT = ""
ARM_LOCATION = ""
ARM_SUBSCRIPTION_ID = ""
ARM_TENANT_ID = ""
expressroute_settings = ""
firewall_settings = ""
peering_settings = ""
vnet_transit_object = ""
vnet_shared_services_object = ""
logging_settings = ""
route_tables
global_settings
