## Features
- CLI-friendly: Read HCL from stdin, edit and write to stdout, easily pipe and combine other commands
- Token-based edit: You can update lots of existing HCL files with automation scripts without losing comments.
- Schemaless: No dependency on specific HCL application binary or schema
- Support HCL2 (not HCL1)
- Available operations:
- attribute append/get/rm/set
- block append/get/list/mv/rm
- body get
- fmt
The hcledit focuses on editing HCL with command line, doesn't aim for generic query tools. It was originally born for refactoring Terraform configurations, but it's not limited to specific applications.
The HCL specification is somewhat generic, so usability takes precedence over strictness if there is room for interpreting meanings in the schemaless approach.
