A Rust CLI tool that converts escaped strings embedded in YAML ConfigMaps into properly formatted multi-line strings using YAML's pipe (|) syntax.

Install directly from crates.io using cargo:

cargo install rsp-cli

1. Clone the repository:

git clone <repository-url>
cd rsp

2. Build the project:

# Install from source
cargo install --path .

3. The binary will be available at target/release/rsp

• Rust 1.70+ (uses Rust 2024 edition)
• Cargo package manager

Process a YAML ConfigMap file and output to stdout:

rsp peel input.yaml

Process a file and save to output file:

rsp peel input.yaml -o output.yaml

Process a file from pipe:

cat input.yaml |rsp peel

RSP transforms hard-to-read escaped strings in Kubernetes ConfigMaps into human-readable format:

Before:

apiVersion: v1
kind: ConfigMap
metadata:
  name: example-config
data:
  config.json: "{\"hello\":\"test\",\n  \"foo\":\"bar\"\n}"

After:

apiVersion: v1
kind: ConfigMap
metadata:
  name: example-config
data:
  config.json: |
    {"hello":"test",
      "foo":"bar"
    }

RSP automatically processes string values for keys ending with:

• .yaml or .yml
• .json
• .toml

Run the comprehensive test suite:

# Run all tests
cargo test

# Run specific test categories
cargo test --test peeler_tests     # Core functionality
cargo test --test cli_tests        # CLI integration  
cargo test --test edge_cases_tests # Edge cases and error handling

The project uses GitHub Actions for continuous integration:

• Build: Compiles the project
• Test: Runs all test suites
• Lint: Checks formatting (rustfmt) and code quality (clippy)
• Audit: Scans for security vulnerabilities

This project is open source. Please check the repository for license information.

We welcome contributions! Please follow these guidelines:

1. Testing: Run the full test suite before submitting changes:

   cargo test --all --verbose

2. Code Quality: Ensure your code passes all checks:

   cargo check
   cargo clippy

3. Documentation: Update documentation for any new features or changes

4. Commit Messages: Use clear, descriptive commit messages

5. Pull Requests:

   • Create feature branches from the main branch
   • Include tests for new functionality
   • Ensure all CI checks pass

• src/main.rs - Main CLI entry point
• src/cli.rs - Command-line interface
• src/peeler.rs - Core YAML processing logic
• src/error.rs - Error handling
• tests/ - Comprehensive test suite
