Functions

func CloseAction

func CloseAction(fn func(ctx context.Context, shutdown <-chan struct{}) error) error

CloseAction runs the function in the background, until it finishes or until it is closed by the user with an interrupt.

func FindMonorepoRoot

func FindMonorepoRoot(startDir string) (string, error)

FindMonorepoRoot will recursively search upwards for a go.mod file. This depends on the structure of the monorepo having a go.mod file at the root.

func FlagNameToEnvVarName

func FlagNameToEnvVarName(f string, prefix string) string

func FormatVersion

func FormatVersion(version string, gitCommit string, gitDate string, meta string) string

func ParseAddress

func ParseAddress(address string) (common.Address, error)

ParseAddress parses an ETH address from a hex string. This method will fail if the address is not a valid hexadecimal address.

func PrefixEnvVar

func PrefixEnvVar(prefix, suffix string) []string

PrefixEnvVar adds a prefix to the environment variable, and returns the env-var wrapped in a slice for usage with urfave CLI v2.

func ValidateEnvVars

func ValidateEnvVars(prefix string, flags []cli.Flag, log log.Logger)

ValidateEnvVars logs all env vars that are found where the env var is prefixed with the supplied prefix (like OP_BATCHER) but there is no actual env var with that name. It helps validate that the supplied env vars are in fact valid.

func WarnOnDeprecatedFlags

func WarnOnDeprecatedFlags(ctx *cli.Context, deprecatedFlags []cli.Flag, log log.Logger)

WarnOnDeprecatedFlags iterates through the provided deprecatedFlags and logs a warning for each that is set.
