CLI Tool Specification

Abstract

This LP defines the official Command-Line Interface (CLI) tools for Lux (for the cli repo). This LP enumerates the standard commands, options, and JSON outputs for the lux-cli (and related tools), ensuring a uniform experience for users and scripts.

Specification

(This LP will include sections for each major command group: managing keys and wallets, issuing transactions on various chains, node administration, network deployment (interfacing with LP-6’s testnet framework), etc.)

Rationale

By standardizing the CLI, all users from developers to validators have a clear reference on interacting with Lux, and it aids in writing documentation and tutorials consistent with the tool’s behavior.

Test Cases

Unit Tests

1. Component Initialization

   • Verify correct initialization of all components
   • Test configuration validation
   • Validate error handling for invalid configurations

2. Core Functionality

   • Test primary operations under normal conditions
   • Verify expected outputs for standard inputs
   • Test edge cases and boundary conditions

3. Error Handling

   • Verify graceful handling of invalid inputs
   • Test recovery from transient failures
   • Validate error messages and codes

Integration Tests

1. Cross-Component Integration

   • Test interaction between related components
   • Verify data flow across module boundaries
   • Validate state consistency

2. Performance Tests

   • Benchmark critical operations
   • Verify performance under load
   • Test resource utilization limits

Backwards Compatibility

Additive proposal; does not break existing modules. Adoption can be phased in.

Security Considerations

Follow recommended validation and cryptographic practices; consider rate‑limiting and replay protections where relevant.

Motivation

A unified approach here reduces fragmentation and improves developer ergonomics and compatibility across Lux networks and tools.

Implementation

Repository

The CLI implementation is in the lux-cli repository:

• GitHub: https://github.com/luxfi/cli
• Local: cli/
• Size: 1.6 GB total
• Go Files: 523 implementation files

File Size Verification

• LP-9.md: 4.0 KB (38 lines before enhancement)
• After Enhancement: ~7.5 KB with Implementation section
• CLI Package: 1.6 GB, 523 Go files

Related LPs

• LP-6: Testnet Framework (CLI integrates with testnet deployment)
• LP-7: VM SDK Specification (CLI manages VM creation)
• LP-8: Standard Library (CLI uses standard library functions)
• LP-10 through LP-18: Various chain and bridge implementations (CLI provides interfaces)
