func GetIntFromEnv ¶

func GetIntFromEnv(envVar string, defaultValue, minValue, maxValue int, log *logger.Logger) int

GetIntFromEnv is a generic helper that reads an integer value from an environment variable, validates it against min/max bounds, and returns a default value if invalid. This follows the configuration helper pattern from pkg/workflow/config_helpers.go.

Parameters:

• envVar: The environment variable name (e.g., "GH_AW_MAX_CONCURRENT_DOWNLOADS")
• defaultValue: The default value to return if env var is not set or invalid
• minValue: Minimum allowed value (inclusive)
• maxValue: Maximum allowed value (inclusive)
• log: Optional logger for debug output

Returns the parsed integer value, or defaultValue if:

• Environment variable is not set
• Value cannot be parsed as an integer
• Value is outside the [minValue, maxValue] range

Invalid values trigger warning messages to stderr.
