HCL parser fails on multi-line boolean expressions with && operator

[mmclane]

Problem

Terravision's HCL parser (lark-based) fails to parse valid Terraform HCL when using the && operator in multi-line boolean expressions.

Error Message

Unexpected token Token('__ANON_8', '&&') at line 42, column 5

Followed by a secondary IndexError in graphmaker.py:1457 when splitting resource names (likely due to corrupted parser state).

Sample Code That Fails

locals {
  create_monitoring_role = (
    var.create_monitoring_role
    && local.db_config.monitoring_role_arn == null
    && local.db_config.monitoring_interval > 0
  )
}

This is valid Terraform HCL syntax (terraform validate passes), but terravision cannot parse it.

Environment

• Running via Docker image patrickchugh/terravision
• Terraform source with Aurora database modules

Workaround

Rewriting the expression as a single line works:

locals {
  create_monitoring_role = var.create_monitoring_role && local.db_config.monitoring_role_arn == null && local.db_config.monitoring_interval > 0
}

Expected Behavior

Terravision should parse valid Terraform HCL that uses && operators across multiple lines within parentheses.

I have worked around this issue for now by converting it to a single line string.
