🛑 TuskLang Ruby Error Handling Guide

"We don't bow to any king" - Ruby Edition

Build robust Ruby applications with TuskLang's advanced error handling. Validate configs, catch runtime errors, and enforce best practices for reliability.

🚦 Config Validation Errors

1. Syntax Errors

config/bad.tsk
$app_name: "MyApp"
$version: 1.0.0  # Missing quotes (should be string)
[database]
host: "localhost"
port: 5432

test/validate_config.rb
require 'tusklang'
parser = TuskLang.new
begin
  parser.parse_file('config/bad.tsk')
rescue TuskLang::ParseError => e
  puts "❌ Parse error: #{e.message}"
end

2. Schema Validation Errors

config/schema.tsk
[database]
host: string
port: integer

test/schema_validation.rb
require 'tusklang'
parser = TuskLang.new
parser.schema_file = 'config/schema.tsk'
begin
  parser.parse_file('config/app.tsk')
rescue TuskLang::SchemaError => e
  puts "❌ Schema error: #{e.message}"
end

🛠️ Runtime Error Handling

1. Rescue in Ruby Code

app/services/config_loader.rb
require 'tusklang'
class ConfigLoader
  def self.load(file)
    parser = TuskLang.new
    parser.parse_file(file)
  rescue TuskLang::ParseError, TuskLang::SchemaError => e
    Rails.logger.error("Config error: #{e.message}")
    nil
  end
end

2. Fallback Defaults

app/services/config_loader.rb
class ConfigLoader
  def self.load_with_fallback(file, fallback = {})
    parser = TuskLang.new
    parser.parse_file(file)
  rescue
    fallback
  end
end

🛡️ Best Practices

- Always validate configs before loading. - Rescue and log all config-related errors. - Provide sensible defaults for critical settings. - Monitor error logs and set up alerts for failures.
