Pattern

regexJS
resource\s+"([\w\-]+)"\s+"([\w\-]+)"\s*\{   (flags: g)

JavaScript / ECMAScript code

jsJavaScript
const re = new RegExp("resource\\s+\"([\\w\\-]+)\"\\s+\"([\\w\\-]+)\"\\s*\\{", "g");
const input = "resource \"aws_s3_bucket\" \"main\" { bucket = \"my-app\" }";
const matches = [...input.matchAll(re)];
console.log(matches.map(m => m[0]));

Uses `String.prototype.matchAll` for global iteration (Node 12+ / all modern browsers).

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
