Expected Behaviour

Seed command should produce a tfvars file

Current Behavior

Terraspace seed command fails when variables.tf contains a one-line variable declaration

Step-by-step reproduction instructions

1. terraspace new stack bob
2. Edit app/stacks/bob/variables.tf

variable "var_0" {}
variable "var_n" {}

3. TS_ENV=alice terraspace seed bob

Results in error message:

hcl_parser-0.2.1/lib/hcl_parser/loader.rb:56:in `block in rewrite_complex_types': bad value for range (ArgumentError)

Error appears to be the logic that assumes the closing brace of a variable will be the first char on a line, because the following variables.tf results in no error when the seed command is run:

# app/stacks/bob/variables.tf
variable "var_0" {}
variable "var_n" {
}

Solution Suggestion

Modify hcl_parser/loader.rb to match a closing brace anywhere on a line in variables.tf

hi, we are experiencing this issue as well and confirm that the workaround for our variables.tf allows us to generate a tfvars.

Fixed in https://github.com/boltops-tools/hcl_parser/pull/5 To use, update the hcl_parser gem to 0.2.2. In your terraspace project

bundle update hcl_parser

This updates the Gemfile.lock pin of hcl_parser. You'll need at least hcl_parser 0.2.2
