◆ AbsPathForConfigVal()

fs::path AbsPathForConfigVal	(	const ArgsManager &	args,
		const fs::path &	path,
		bool	net_specific = true )

Most paths passed as configuration arguments are treated as relative to the datadir if they are not absolute.

Parameters

args	Parsed arguments and settings.
path	The path to be conditionally prefixed with datadir.
net_specific	Use network specific datadir variant

Returns: The normalized path.

Here is the caller graph for this function:

◆ HasTestOption()

bool HasTestOption	(	const ArgsManager &	args,
		const std::string &	test_option )

Checks if a particular test option is present in -test command-line arg options.

Definition at line 749 of file args.cpp.

Here is the caller graph for this function:

◆ HelpMessageGroup()

std::string HelpMessageGroup ( const std::string & message )

Format a string to be used as group of options in help messages.

Parameters

message Group name (e.g. "RPC server options:")

Returns: the formatted string

Definition at line 732 of file args.cpp.

Here is the caller graph for this function:

◆ HelpMessageOpt()

std::string HelpMessageOpt	(	const std::string &	option,
		const std::string &	message )

Format a string to be used as option description in help messages.

Parameters

option	Option message (e.g. "-rpcuser=<user>")
message	Option description (e.g. "Username for JSON-RPC connections")

Returns: the formatted string

◆ HelpRequested()

bool HelpRequested ( const ArgsManager & args )

Returns: true if help has been requested via a command-line arg

Definition at line 717 of file args.cpp.

Here is the caller graph for this function:

◆ InterpretKey()

KeyInfo InterpretKey ( std::string key )

Parse "name", "section.name", "noname", "section.noname" settings keys.

Note: Where an option was negated can be later checked using the IsArgNegated() method. One use case for this is to have a way to disable options that are not normally boolean (e.g. using -nodebuglogfile to request that debug log output is not sent to any file at all).

Definition at line 77 of file args.cpp.

Here is the caller graph for this function:

◆ InterpretValue()

std::optional< common::SettingsValue > InterpretValue	(	const KeyInfo &	key,
		const std::string *	value,
		unsigned int	flags,
		std::string &	error )

Interpret settings value based on registered flags.

Parameters

[in]	key	key information to know if key was negated
[in]	value	string value of setting to be parsed
[in]	flags	ArgsManager registered argument flags
[out]	error	Error description if settings value is not valid

Returns: parsed settings value if it is valid, otherwise nullopt accompanied by a descriptive error string
