Functions

func CheckTendermintError

func CheckTendermintError(err error, txBytes []byte) *sdk.TxResponse

CheckTendermintError checks if the error returned from BroadcastTx is a Tendermint error that is returned before the tx is submitted due to precondition checks that failed. If an Tendermint error is detected, this function returns the correct code back in TxResponse.

TODO: Avoid brittle string matching in favor of error matching. This requires a change to Tendermint's RPCError type to allow retrieval or matching against a concrete error type.

func CreateVerifier

func CreateVerifier(ctx CLIContext, cacheSize int) (tmlite.Verifier, error)

CreateVerifier returns a Tendermint verifier from a CLIContext object and cache size. An error is returned if the CLIContext is missing required values or if the verifier could not be created. A CLIContext must at the very least have the chain ID and home directory set. If the CLIContext has TrustNode enabled, no verifier will be created.

func ErrInvalidAccount

func ErrInvalidAccount(addr sdk.AccAddress) error

ErrInvalidAccount returns a standardized error reflecting that a given account address does not exist.

func ErrVerifyCommit

func ErrVerifyCommit(height int64) error

ErrVerifyCommit returns a common error reflecting that the blockchain commit at a given height can't be verified. The reason is that the base checkpoint of the certifier is newer than the given height

func GetFromFields

func GetFromFields(input io.Reader, from string, genOnly bool) (sdk.AccAddress, string, error)

GetFromFields returns a from account address and Keybase name given either an address or key name. If genOnly is true, only a valid Bech32 cosmos address is returned.

}

CLIContext implements a typical CLI context created in SDK modules for transaction handling and queries.

func NewCLIContext

func NewCLIContext() CLIContext

NewCLIContext returns a new initialized CLIContext with parameters from the command line using Viper.

func NewCLIContextWithFrom

func NewCLIContextWithFrom(from string) CLIContext

NewCLIContextWithFrom returns a new initialized CLIContext with parameters from the command line using Viper. It takes a key name or address and populates the FromName and FromAddress field accordingly. It will also create Tendermint verifier using the chain ID, home directory and RPC URI provided by the command line. If using a CLIContext in tests or any non CLI-based environment, the verifier will not be created and will be set as nil because FlagTrustNode must be set.

func NewCLIContextWithInput

func NewCLIContextWithInput(input io.Reader) CLIContext

NewCLIContextWithInput returns a new initialized CLIContext with a io.Reader and parameters from the command line using Viper.

func NewCLIContextWithInputAndFrom

func NewCLIContextWithInputAndFrom(input io.Reader, from string) CLIContext

NewCLIContextWithInputAndFrom returns a new initialized CLIContext with parameters from the command line using Viper. It takes a io.Reader and and key name or address and populates the FromName and FromAddress field accordingly. It will also create Tendermint verifier using the chain ID, home directory and RPC URI provided by the command line. If using a CLIContext in tests or any non CLI-based environment, the verifier will not be created and will be set as nil because FlagTrustNode must be set.

func (CLIContext) BroadcastTx

func (ctx CLIContext) BroadcastTx(txBytes []byte) (res sdk.TxResponse, err error)

BroadcastTx broadcasts a transactions either synchronously or asynchronously based on the context parameters. The result of the broadcast is parsed into an intermediate structure which is logged if the context has a logger defined.

func (CLIContext) BroadcastTxAsync

func (ctx CLIContext) BroadcastTxAsync(txBytes []byte) (sdk.TxResponse, error)

BroadcastTxAsync broadcasts transaction bytes to a Tendermint node asynchronously (i.e. returns immediately).

func (CLIContext) BroadcastTxCommit

func (ctx CLIContext) BroadcastTxCommit(txBytes []byte) (sdk.TxResponse, error)

BroadcastTxCommit broadcasts transaction bytes to a Tendermint node and waits for a commit. An error is only returned if there is no RPC node connection or if broadcasting fails.

NOTE: This should ideally not be used as the request may timeout but the tx may still be included in a block. Use BroadcastTxAsync or BroadcastTxSync instead.

func (CLIContext) BroadcastTxSync

func (ctx CLIContext) BroadcastTxSync(txBytes []byte) (sdk.TxResponse, error)

BroadcastTxSync broadcasts transaction bytes to a Tendermint node synchronously (i.e. returns after CheckTx execution).

func (CLIContext) GetFromAddress

func (ctx CLIContext) GetFromAddress() sdk.AccAddress

GetFromAddress returns the from address from the context's name.

func (CLIContext) GetFromName

func (ctx CLIContext) GetFromName() string

GetFromName returns the key name for the current context.

func (CLIContext) GetNode

func (ctx CLIContext) GetNode() (rpcclient.Client, error)

GetNode returns an RPC client. If the context's client is not defined, an error is returned.

func (CLIContext) PrintOutput

func (ctx CLIContext) PrintOutput(toPrint interface{}) error

PrintOutput prints output while respecting output and indent flags NOTE: pass in marshalled structs that have been unmarshaled because this function will panic on marshaling errors
