Helix Configuration - Configuration Without the Headaches

Overview

Helix Configuration is a purpose-built configuration language designed for AI systems. No more TOML limitations, JSON verbosity, or environment variable chaos. This is configuration that understands AI workflows, agents, and pipelines natively. Designed and built for Maestro.ps

Current Status: W.I.P. not production-ready with but do have a full compiler, CLI tools, and comprehensive language features.

Why Helix Configuration?

Crates install: cargo build --release --features full && hlx install

The Problems We Solved

TOML Problems:

No native support for complex structures
Arrays of tables are a nightmare
No conditionals or references
Limited type system
Can't express workflows or pipelines

JSON Problems:

Verbose and unreadable
No comments (seriously?)
Everything is a string or number
No duration types (30m → "30m" → parse → pray)
Trailing comma hell

ENV Variables Problems:

Everything is a string
No structure or hierarchy
No validation
Scattered across shell scripts
No version control friendly

YAML Problems:

Whitespace sensitivity disasters
Norway problem (no: false)
Ambiguous types
Anchors and references are cryptic
Multi-line strings are painful

The helix Solution

Built for AI Configuration:

Native AI constructs - agents, workflows, pipelines, crews
Rich type system - durations (30m), references ($VAR), tags (@memory.key)
Hierarchical structure - Clean nesting without the pain
Comments - Because documentation matters
Validation - Catch errors at compile time, not runtime
Binary compilation - Parse once, load instantly

Type System

Primitive Types

string_value = "Hello, World"
number_value = 42
float_value = 3.14
boolean_value = true
null_value = null

Duration Types

# All of these work naturally
timeout = 30s      # 30 seconds
delay = 5m        # 5 minutes  
cache_ttl = 24h   # 24 hours
retention = 7d    # 7 days

References

# Environment variables
api_key = $API_KEY

# Memory references
context = @memory.conversation.latest

# Variable references
base_url = ${config.api.endpoint}

Environment Variables

# Pull from shell environment, .bashrc, or .env files
agent "my-agent" {
    model = $ANTHROPIC_API_KEY
    tools = ["tool1", "tool2"]
}

context "production" {
    secrets {
        # Environment variables
        db_password = $DATABASE_PASSWORD
        api_key = $MY_API_KEY

        # Vault references (for sensitive data)
        cert_path = "vault:ssl/certificate"
        private_key = "vault:ssl/private_key"
    }

    variables {
        # Regular configuration values
        api_endpoint = "https://api.production.com"
        timeout = 30s
        max_retries = 3
    }
}

Setting up Environment Variables:

# In your .bashrc, .zshrc, or .env file
export ANTHROPIC_API_KEY="your-key-here"
export DATABASE_PASSWORD="your-password"
export MY_API_KEY="another-key"

# helix will automatically pick these up

Arrays

# Simple arrays
tags = ["rust", "systems", "performance"]

# Multi-line arrays
capabilities [
    "reasoning"
    "generation"
    "analysis"
]

Objects

# Inline objects
metadata = { version = "1.0", stable = true }

# Nested objects
config {
    api {
        endpoint = "https://api.example.com"
        timeout = 30s
    }
}

Special Constructs

Pipeline Flow:

pipeline {
    fetch -> process -> validate -> store
}

Hierarchical Tags:

tags [
    "capability:reasoning:logical"
    "model:gpt-4"
    "context:conversation"
]

Weighted Values:

priority = "high:0.9"
confidence = "certain:0.95"

Parser Architecture

helix Source Code
      ↓
   [Lexer]  → Tokens
      ↓
   [Parser] → AST
      ↓
  [Validator] → Validated AST
      ↓
  [Compiler] → Binary Format

Lexer

Converts text into tokens:

Keywords (agent, workflow, context, etc.)
Identifiers
Literals (strings, numbers, durations)
Operators (=, ->, [, ], {, })

Parser

Builds Abstract Syntax Tree (AST):

Declarations (agents, workflows, contexts)
Expressions (values, references, arrays)
Statements (assignments, blocks)

Validator

Ensures correctness:

Type checking
Reference validation
Dependency resolution
Constraint verification

Usage

In Rust Code

use helix_config::{parse, helixConfig};

// Parse from string
let config_str = r#"
    agent "assistant" {
        model = "gpt-4"
        temperature = 0.7
    }
"#;

let config = parse(config_str)?;
let agent = config.agents.get("assistant").unwrap();

File Loading

use helix_config::helixLoader;

let mut loader = helixLoader::new();

// Load single file
let config = loader.load_file("config.hlxbb")?;

// Load directory of .hlxbb files
loader.load_directory("./configs")?;

// Access merged configuration
let merged = loader.get_merged_config();

With Validation

use helix_config::{parse_and_validate, ValidationRules};

let rules = ValidationRules {
    require_version: true,
    max_agents: Some(100),
    allowed_models: vec!["gpt-4", "claude-3"],
};

let config = parse_and_validate(source, rules)?;

Best Practices

1. Organization

# Group related configurations
# agents.hlxbb
agent "coder" { ... }
agent "reviewer" { ... }

# workflows.hlxbb  
workflow "ci" { ... }
workflow "cd" { ... }

# config.hlxbb
memory { ... }
context "prod" { ... }

2. Naming Conventions

# Use descriptive names
agent "senior-rust-engineer"  # Good
agent "sre"                   # Too short
agent "a1"                     # Meaningless

# Use consistent separators
workflow "code-review-pipeline"  # kebab-case
context "production_environment"  # snake_case (pick one!)

3. Comments

# Document why, not what
agent "specialist" {
    # Higher temperature for creative problem solving
    temperature = 0.9
    
    # Limit tokens to control costs in development
    max_tokens = 50000
}

4. Reusability

# Define base configurations (future feature)
base_agent {
    temperature = 0.7
    max_tokens = 100000
}

agent "coder" extends base_agent {
    model = "gpt-4"
    role = "Developer"
}

Error Messages

Helix Configuration provides clear, actionable error messages:

Error at line 15, column 8:
    timeout = "30 minutes"
              ^^^^^^^^^^^^
Expected duration type (e.g., 30m, 1h, 5s)

Error at line 23:
    agent = "undefined-agent"
            ^^^^^^^^^^^^^^^^^
Reference to undefined agent. Available agents:
  - senior-rust-engineer
  - code-reviewer
  - test-engineer

Migration Guide

From TOML

# Before (TOML)
[agent.coder]

agent "coder" {
    model = "gpt-4"
    temperature = 0.7
    capabilities ["rust", "python"]
}

From JSON

// Before (JSON)
{
  "workflow": {
    "name": "ci",
    "timeout": "30m",
    "steps": [...]
  }
}

# After (helix)
workflow "ci" {
    timeout = 30m  # Native duration!
    step { ... }
}

From YAML

# Before (YAML)
agent:
  name: coder
  config:
    model: gpt-4
    temperature: 0.7

# After (helix)
agent "coder" {
    model = "gpt-4"
    temperature = 0.7
}
