Configuration language designed specifically for AI systems
Documentation

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.

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 &&

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

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

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"

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

From YAML

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