Functions

func CheckTendermintError 

func CheckTendermintError(err error, tx tmtypes.Tx) *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 GetFromFields 

func GetFromFields(kr keyring.Keyring, from string, genOnly bool) (sdk.AccAddress, string, keyring.KeyType, error)

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

func NewClientFromNode 

func NewClientFromNode(nodeURI string) (*rpchttp.HTTP, error)

NewClientFromNode sets up Client implementation that communicates with a Tendermint node over JSON RPC and WebSockets TODO: We might not need to manually append `/websocket`: https://github.com/cosmos/cosmos-sdk/issues/8986

func NewKeyringFromBackend 

func NewKeyringFromBackend(ctx Context, backend string) (keyring.Keyring, error)

NewKeyringFromBackend gets a Keyring object from a backend

func Paginate 

func Paginate(numObjs, page, limit, defLimit int) (start, end int)

Paginate returns the correct starting and ending index for a paginated query, given that client provides a desired page and limit of objects and the handler provides the total number of objects. The start page is assumed to be 1-indexed. If the start page is invalid, non-positive values are returned signaling the request is invalid; it returns non-positive values if limit is non-positive and defLimit is negative.

func ReadPageRequest 

func ReadPageRequest(flagSet *pflag.FlagSet) (*query.PageRequest, error)

ReadPageRequest reads and builds the necessary page request flags for pagination.

func SetCmdClientContext 

func SetCmdClientContext(cmd *cobra.Command, clientCtx Context) error

SetCmdClientContext sets a command's Context value to the provided argument.

func SetCmdClientContextHandler 

func SetCmdClientContextHandler(clientCtx Context, cmd *cobra.Command) (err error)

SetCmdClientContextHandler is to be used in a command pre-hook execution to read flags that populate a Context and sets that to the command's Context.

func TxServiceBroadcast 

func TxServiceBroadcast(grpcCtx context.Context, clientCtx Context, req *tx.BroadcastTxRequest) (*tx.BroadcastTxResponse, error)

TxServiceBroadcast is a helper function to broadcast a Tx with the correct gRPC types from the tx service. Calls `clientCtx.BroadcastTx` under the hood.

func ValidateCmd 

func ValidateCmd(cmd *cobra.Command, args []string) error

ValidateCmd returns unknown command error or Help display if help flag set
