func ExtendedStringToName

func ExtendedStringToName(s string) (val uint64, err error)

ExtendedStringToName acts similar to StringToName with the big differences that it will automtically try to infer from which format to convert to a name. Current rules are: - If the `s` contains a `,` character, assumes it's a `Symbol` - If the `s` contains only upper-case characters and length is <= 7, assumes it's a `SymbolCode` - Otherwise, forwards `s` to `StringToName` directly

	}

	content, err := json.MarshalIndent(signedTx, "", "  ")
	if err != nil {
		panic(fmt.Errorf("json marshalling transaction: %s", err))
	}

	fmt.Println(string(content))
	fmt.Println()

	response, err := api.PushTransaction(packedTx)
	if err != nil {
		panic(fmt.Errorf("push transaction: %s", err))
	}

	fmt.Printf("Transaction [%s] submitted to the network succesfully.\n", hex.EncodeToString(response.Processed.ID))

	// In a real-world scenario, would you probably integrate with a real wallet or something similar
	envName := "EOS_GO_PRIVATE_KEY"
	privateKey := os.Getenv(envName)

func (*API) SignTransaction

func (api *API) SignTransaction(tx *Transaction, chainID Checksum256, compression CompressionType) (*SignedTransaction, *PackedTransaction, error)

SignTransaction will sign and pack a transaction, but not submit to the chain. It lives on the `api` object because it might query the blockchain to learn which keys are required to sign this particular transaction.

You can override the way we request keys (which defaults to `api.GetRequiredKeys()`) with SetCustomGetRequiredKeys().

To sign a transaction, you need a Signer defined on the `API` object. See SetSigner.

type APIError

type APIError struct {

	ErrorStruct struct {
		Code    int              `json:"code"` // https://docs.google.com/spreadsheets/d/1uHeNDLnCVygqYK-V01CFANuxUwgRkNkrmeLm9MLqu9c/edit#gid=0
		Name    string           `json:"name"`

	} `json:"error"`
}

func (APIError) Error

func (e APIError) Error() string

func (APIError) IsUnknownKeyError

func (e APIError) IsUnknownKeyError() bool

IsUnknowKeyError determines if the APIError is a 500 error with an `unknown key` message in at least one of the detail element. Some endpoint like `/v1/chain/get_account` returns a body in the form:

```

 {
 	"code": 500,
 	"message": "Internal Service Error",
 	"error": {
 		"code": 0,
 		"name": "exception",
 		"what": "unspecified",
 		"details": [
		 		{
		 			"message": "unknown key (<... redacted ...>): (0 eos.rex)",
		 			"file": "http_plugin.cpp",
		 			"line_number": 589,
		 			"method": "handle_exception"
		 		}
 		]
 	}
 }

```

This will check if root code is a 500, that inner error code is 0 and there is a detail message starting with prefix `"unknown key"`.

	// contains filtered or unexported fields
}

`eosiowd` wallet-based signer

func NewWalletSigner

func NewWalletSigner(api *API, walletName string) *WalletSigner

NewWalletSigner takes an `api`, because often the wallet will be a second endpoint, and not the server node with whom you're pushing transactions to.
