Terraform Resource Block Header in GO
Match the opening line of a Terraform `resource "type" "name" {` block, capturing the resource type and local name.
Try it in the GO tester →Pattern
regexGO
resource\s+"([\w\-]+)"\s+"([\w\-]+)"\s*\{ (flags: g)Go (RE2) code
goGo
package main
import (
"fmt"
"regexp"
)
func main() {
re := regexp.MustCompile(`resource\s+"([\w\-]+)"\s+"([\w\-]+)"\s*\{`)
input := `resource "aws_s3_bucket" "main" { bucket = "my-app" }`
for _, match := range re.FindAllString(input, -1) {
fmt.Println(match)
}
}Uses `regexp.MustCompile` (panics on bad patterns at startup) and `FindAllString` for all matches.
How the pattern works
resource\s+ matches the keyword and required whitespace. "([\w\-]+)" captures the resource type (e.g. `aws_instance`). "([\w\-]+)" captures the local name. The trailing `\s*\{` confirms a block opener (so we don't match string-literal `resource "x" "y"` in a comment).
Examples
Input
resource "aws_s3_bucket" "main" { bucket = "my-app" }Matches
resource "aws_s3_bucket" "main" {
Input
resource "google_storage_bucket" "backups" {Matches
resource "google_storage_bucket" "backups" {
Input
data "aws_caller_identity" "current" {}No match
