lightning-setconfig -- Dynamically change some config options

SYNOPSIS

setconfig config [val]

DESCRIPTION

The setconfig RPC command allows you set the (dynamic) configuration option named by config: options which take a value (as separate from simple flag options) also need a val parameter.

This new value will also be written at the end of the config file, for persistence across restarts (and any old value commented out).

You can see what options are dynamically adjustable using lightning-listconfigs(7). Note that you can also adjust existing options for stopped plugins; they will have an effect when the plugin is restarted.

RETURN VALUE

On success, an object containing config is returned. It is an object containing:

config (string): name of the config variable which was set
source (string): source of configuration setting (file:linenum)
dynamic (boolean): whether this option is settable via setconfig (always true)
plugin (string, optional): the plugin this configuration setting is for
set (boolean, optional): for simple flag options
value_str (string, optional): for string options
value_msat (msat, optional): for msat options
value_int (integer, optional): for integer options
value_bool (boolean, optional): for boolean options

ERRORS

The following error codes may occur:

-32602: JSONRPC2_INVALID_PARAMS, i.e. the parameter is not dynamic, or the val was invalid.
