Typedef Documentation

◆ ExecuteCommand

using nfd::tools::nfdc::ExecuteCommand = typedef std::function<void(ExecuteContext&)>

A function to execute a command.

Definition at line 91 of file execute-command.hpp.

Enumeration Type Documentation

◆ ArgValueType

enum nfd::tools::nfdc::ArgValueType

strong

Indicates argument value type.

Enumerator
NONE	Boolean argument without value. The argument appears in CommandArguments as bool value `true`. It must not be declared as positional.
ANY	Any arguments. The argument appears in CommandArguments as std::vector<std::string>. It must be declared as positional, and will consume all subsequent tokens.
BOOLEAN	Boolean. The argument appears in CommandArguments as bool.
UNSIGNED	Non-negative integer. The argument appears in CommandArguments as uint64_t. Acceptable input range is [0, std::numeric_limits<int64_t>::max()].
STRING	Arbitrary string. The argument appears in CommandArguments as std::string.
REPORT_FORMAT	Report format 'xml' or 'text'. The argument appears in CommandArguments as nfd::tools::nfdc::ReportFormat.
NAME	Name prefix. The argument appears in CommandArguments as ndn::Name.
FACE_URI	FaceUri. The argument appears in CommandArguments as ndn::FaceUri.
FACE_ID_OR_URI	FaceId or FaceUri. The argument appears in CommandArguments as either uint64_t or ndn::FaceUri.
FACE_PERSISTENCY	Face persistency 'persistent' or 'permanent'. The argument appears in CommandArguments as ndn::nfd::FacePersistency.
ROUTE_ORIGIN	Route origin. The argument appears in CommandArguments as ndn::nfd::RouteOrigin.

Definition at line 48 of file forwarder-general-module.cpp.

◆ canonize()

std::pair< std::optional< FaceUri >, std::string > nfd::tools::nfdc::canonize	(	ExecuteContext &	ctx,
		const FaceUri &	uri
	)

Canonize a FaceUri.

Returns: canonical FaceUri (nullopt on failure) and error string

Definition at line 181 of file face-helpers.cpp.

◆ canonizeErrorHelper()

std::pair< FindFace::Code, std::string > nfd::tools::nfdc::canonizeErrorHelper	(	const FaceUri &	uri,
		const std::string &	error,
		const std::string &	field = `""`
	)

Helper to generate exit code and error message for face canonization failures.

Parameters

uri	The FaceUri
error	The error string returned by the canonization process
field	An optional field identifier to include with the message

Returns: exit code and error message

◆ help()

int nfd::tools::nfdc::help	(	std::ostream &	os,
		const CommandParser &	parser,
		std::vector< std::string >	args
	)

Tries to help the user, if requested on the command line.

Depending on the provided command line arguments args, this function can either open the man page for a specific command, or list all commands available in parser. In the former case, this function never returns if successful.

Return values

0	a list of available commands was successfully written to `os`
1	help was requested, but an error was encountered while exec'ing the `man` binary
2	help was not provided because `args` did not contain any help-related options

Writes the list of available commands to a stream.

Parameters

os	the output stream to write the list to
parser	instance of CommandParser containing the commands to list
mode	only the commands available in this mode are listed
noun	if not empty, only the commands starting with this noun are listed
