Functions

func AddFlags 

func AddFlags(cmd *cobra.Command, desc FlagDesc)

AddFlags from desc to cmd. Required flags are marked as required.

func FormatLongDesc 

func FormatLongDesc(longString string, meta *LongMetadata) string

func FormatLongDescDirect 

func FormatLongDescDirect(longString, moduleName string) string

func GetParams 

func GetParams[reqP proto.Message, querier any](moduleName string,
	newQueryClientFn func(grpc1.ClientConn) querier,
) *cobra.Command

func IndexCmd 

func IndexCmd(moduleName string) *cobra.Command

Index command, but short is not set. That is left to caller.

func ParseCoin 

func ParseCoin(arg, fieldName string) (sdk.Coin, error)

TODO: Make this able to read from some local alias file for denoms.

func ParseCoins 

func ParseCoins(arg, fieldName string) (sdk.Coins, error)

TODO: Make this able to read from some local alias file for denoms.

func ParseDenom 

func ParseDenom(arg, _ string) (string, error)

func ParseExpectedQueryFnName 

func ParseExpectedQueryFnName[reqP any]() string

func ParseField 

func ParseField(
	v reflect.Value,
	t reflect.Type,
	fieldIndex int,
	arg string,
	flagAdvice FlagAdvice,
	flags *pflag.FlagSet,
) (bool, error)

ParseField parses field #fieldIndex from either an arg or a flag. Returns true if it was parsed from an argument. Returns error if there was an issue in parsing this field.

func ParseFieldFromArg 

func ParseFieldFromArg(fVal reflect.Value, fType reflect.StructField, arg string) error

func ParseFieldFromFlag 

func ParseFieldFromFlag(
	fVal reflect.Value,
	fType reflect.StructField,
	flagAdvice FlagAdvice,
	flags *pflag.FlagSet,
) (bool, error)

ParseFieldFromFlag attempts to parses the value of a field in a struct from a flag. The field is identified by the provided `reflect.StructField`. The flag advice and `pflag.FlagSet` are used to determine the flag to parse the field from. If the field corresponds to a value from a flag, true is returned. Otherwise, `false` is returned. In the true case, the parsed value is set on the provided `reflect.Value`. An error is returned if there is an issue parsing the field from the flag.

func ParseFieldsFromFlagsAndArgs 

func ParseFieldsFromFlagsAndArgs[reqP any](flagAdvice FlagAdvice, flags *pflag.FlagSet, args []string) (reqP, error)

Parses arguments 1-1 from args makes an exception, where it allows Pagination to come from flags.

func ParseFloat 

func ParseFloat(arg, fieldName string) (float64, error)

func ParseHasPagination 

func ParseHasPagination[reqP any]() bool

func ParseInt 

func ParseInt(arg, fieldName string) (int64, error)

func ParseIntMaybeNegative 

func ParseIntMaybeNegative(arg, fieldName string) (int64, error)

func ParseNumFields 

func ParseNumFields[reqP any]() int

func ParseSdkDec 

func ParseSdkDec(arg, fieldName string) (sdk.Dec, error)

func ParseSdkInt 

func ParseSdkInt(arg, fieldName string) (math.Int, error)

TODO: This really shouldn't be getting used in the CLI, its misdesign on the CLI ux

func ParseUint 

func ParseUint(arg, fieldName string) (uint64, error)

func ParseUnixTime 

func ParseUnixTime(arg, fieldName string) (time.Time, error)

func QueryIndexCmd 

func QueryIndexCmd(moduleName string) *cobra.Command

func RunQueryTestCase 

func RunQueryTestCase[Q proto.Message](t *testing.T, desc *QueryDescriptor, tc QueryCliTestCase[Q])

func RunQueryTestCases 

func RunQueryTestCases[Q proto.Message](t *testing.T, desc *QueryDescriptor, testcases map[string]QueryCliTestCase[Q])

func RunTxTestCase 

func RunTxTestCase[M sdk.Msg](t *testing.T, desc *TxCliDesc, tc TxCliTestCase[M])

func RunTxTestCases 

func RunTxTestCases[M sdk.Msg](t *testing.T, desc *TxCliDesc, testcases map[string]TxCliTestCase[M])

func SimpleQueryCmd 

func SimpleQueryCmd[reqP proto.Message, querier any](use, short, long string,
	moduleName string, newQueryClientFn func(grpc1.ClientConn) querier,
) *cobra.Command

SimpleQueryCmd builds a query, for the common, simple case. It detects that the querier function name is the same as the ProtoMessage name, with just the "Query" and "Request" args chopped off. It expects all proto fields to appear as arguments, in order.

func TxIndexCmd 

func TxIndexCmd(moduleName string) *cobra.Command
