◆ 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.

◆ 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

◆ HelpMessageOpt()

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

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

◆ InterpretOption()

util::SettingsValue InterpretOption	(	std::string &	section,
		std::string &	key,
		const std::string &	value
	)

Interpret -nofoo as if the user supplied -foo=0.

This method also tracks when the -no form was supplied, and if so, checks whether there was a double-negative (-nofoo=0 -> -foo=1).

If there was not a double negative, it removes the "no" from the key and returns false.

If there was a double negative, it removes "no" from the key, and returns true.

If there was no "no", it returns the string value untouched.

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).
