Constant Summary collapse

DEFAULT_ENV =

NOTE: TINA4_SECRET is deliberately ABSENT here. The default signing secret must never become a guessable built-in. A blank secret is the signal for Auth.ensure_dev_secret to mint a per-machine random dev secret (saved to gitignored .env.local) in dev, or to emit the actionable “set TINA4_SECRET” warning in CI/prod. Parity with the Python master.

}.freeze
TRUTHY =

Typed env-var coercion — parity with tina4_python’s Env class, tina4-php’s Tina4Env, and tina4-nodejs’s Env. Truthy values (case-insensitive after strip): “1”, “true”, “on”, “yes”, “y”, “t”. Falsy: “0”, “false”, “off”, “no”, “n”, “f”, empty string. Anything else falls through to default.

.all_env ⇒ Object

Return all current ENV vars as a hash

# File 'lib/tina4/env.rb', line 196

def all_env
  ENV.to_h
end

.bool(name, default: false) ⇒ Object

Read an env var and coerce to Boolean. Returns default when the var is unset or holds a value outside the TRUTHY/FALSY tables. Never raises — bad input falls through to default.

  raw = ENV[name.to_s]
  return default if raw.nil?
  token = raw.strip.downcase
  return true  if TRUTHY.include?(token)
  return false if FALSY.include?(token) || token.empty?
  default
end

.float(name, default: 0.0) ⇒ Object

Read an env var and coerce to Float. Logs a warning via Tina4::Log (if loaded) and returns default on parse failure. Never raises.

  Float(raw.strip)
rescue ArgumentError, TypeError
  log_warning("Env.float(#{name.inspect}): could not parse #{raw.inspect} as Float — using default #{default.inspect}")
  default
end

.get_env(key, default = nil) ⇒ Object

Get an env var value, with optional default

# File 'lib/tina4/env.rb', line 186

def get_env(key, default = nil)
  ENV[key.to_s] || default
end

.has_env?(key) ⇒ Boolean

Check if an env var exists

Returns:

  • (Boolean)

# File 'lib/tina4/env.rb', line 191

def has_env?(key)
  ENV.key?(key.to_s)
end

.int(name, default: 0) ⇒ Object

Read an env var and coerce to Integer. Logs a warning via Tina4::Log (if loaded) and returns default on parse failure. Never raises.

  Integer(raw.strip)
rescue ArgumentError, TypeError
  log_warning("Env.int(#{name.inspect}): could not parse #{raw.inspect} as Integer — using default #{default.inspect}")
  default
end

.is_truthy(val) ⇒ Object

Check if a value is truthy for env boolean checks.

Accepts: “true”, “True”, “TRUE”, “1”, “yes”, “Yes”, “YES”, “on”, “On”, “ON”. Everything else is falsy (including empty string, nil, not set).

def load_env(root_dir = Dir.pwd)
  env_file = resolve_env_file(root_dir)
  unless File.exist?(env_file)
    create_default_env(env_file)
  end
  # Precedence: real-env > .env.local > .env. Both loads are first-wins
  # (override=false / `ENV[key] ||= value`), so a key already present in
  # the real process environment is NEVER clobbered. .env.local loads
  # FIRST so its values beat .env, but a real env var set before boot
  # still wins over both. This is the security-correct ordering: a stray
  # gitignored .env.local (e.g. a stale auto-generated dev secret) must
  # not override an explicitly-set real TINA4_SECRET. The ensure-dev-secret
  # bootstrap runs AFTER this (only mints a secret if still unset in dev).
  load_local_env(root_dir)
  parse_env_file(env_file)
end

.load_local_env(root_dir = Dir.pwd) ⇒ Object

Load .env.local with first-wins semantics (override=false). A real process env var already present wins; this only fills keys not already set. Loaded BEFORE .env so .env.local beats .env (real-env > .env.local > .env). No-op when the file is absent (common for fresh checkouts).

  missing = keys.map(&:to_s).reject { |k| ENV.key?(k) }
  unless missing.empty?
    raise KeyError, "Missing required env vars: #{missing.join(', ')}"
  end
end

.reset_env ⇒ Object

Reset: clear all env vars that were loaded (restore to process defaults)



209
210
211
212
 
# File 'lib/tina4/env.rb', line 209

def reset_env
  @loaded_keys&.each { |k| ENV.delete(k) }
  @loaded_keys = []
end

.str(name, default: "") ⇒ Object

Read an env var as a String. Returns default when unset. Whitespace is preserved — this is a pass-through for the raw env value, matching Python’s Env.str semantics.
