flags

func BindEnv ¶ added in v1.3.1

func BindEnv(fs *pflag.FlagSet, flagName string)

BindEnv wires the canonical DEVSY_* env var into a cobra flag. Call it immediately after the flag's *Var registration. If the env var is set, the value is applied to the flag (Changed=true, satisfying MarkFlagRequired) and the usage string advertises the env var.

Failure modes are loud by design:

• panics if the flag is not registered (programmer bug at startup);
• log.Fatalf if the env value is rejected by the flag's type (operator bug; e.g. DEVSY_DEBUG=garbage on a bool flag). This matches the contract of the prior inheritFlagsFromEnvironment loop so misconfigured env vars are never silently ignored.

func EnvName ¶ added in v1.3.1

func EnvName(flagName string) string

EnvName returns the canonical env var name for a flag under the uniform rule:

config.EnvPrefix + uppercase(flagName) with "-" replaced by "_"

Example: "agent-url" -> "DEVSY_AGENT_URL".
