Parameters
None
Returns
the storeObject
Methods
​computerName​
Signature
hs.network.configuration:computerName() -> name, encoding
Type
Method
Description
Returns the name of the computeras specified in the Sharing Preferences, and its string encoding
Parameters
None
Returns
name - the computer name
encoding - the encoding type
Notes
You can also retrieve this information as key-value pairs with hs.network.configuration:contents("Setup:/System")
​consoleUser​
Signature
hs.network.configuration:consoleUser() -> name, uid, gid
Type
Method
Description
Returns the name of the user currently logged into the system, including the users id and primary group id
Parameters
None
Returns
name - the user name
uid - the user ID for the user
gid - the user's primary group ID
Notes
You can also retrieve this information as key-value pairs with hs.network.configuration:contents("State:/Users/ConsoleUser")
​contents​
Signature
hs.network.configuration:contents([keys], [pattern]) -> table
Type
Method
Description
Return the contents of the store for the specified keys or keys matching the specified pattern(s)
Parameters
keys - a string or table of strings containing the keys or patterns of keys, if pattern is true. Defaults to all keys.
pattern - a boolean indicating wether or not the string(s) provided are to be considered regular expression patterns (true) or literal strings to match (false). Defaults to false.
Returns
a table of key-value pairs from the dynamic store which match the specified keys or key patterns.
Notes
if no parameters are provided, then all key-value pairs in the dynamic store are returned.
​dhcpInfo​
Signature
hs.network.configuration:dhcpInfo([serviceID]) -> table
Type
Method
Description
Return the DHCP information for the specified service or the primary service if no parameter is specified.
Parameters
serviceID - an optional string contining the service ID of the interface for which to return DHCP info. If this parameter is not provided, then the default (primary) service is queried.
Returns
a table containing DHCP information including lease time and DHCP options
Notes
a list of possible Service ID's can be retrieved with hs.network.configuration:contents("Setup:/Network/Global/IPv4")
generates an error if the service ID is invalid or was not assigned an IP address via DHCP.
​hostname​
Signature
hs.network.configuration:hostname() -> name
Type
Method
Description
Returns the current local host name for the computer
Parameters
None
Returns
name - the local host name
Notes
You can also retrieve this information as key-value pairs with hs.network.configuration:contents("Setup:/System")
​keys​
Signature
hs.network.configuration:keys([keypattern]) -> table
Type
Method
Description
Return the keys in the dynamic store which match the specified pattern
Parameters
keypattern - a regular expression specifying which keys to return (defaults to ".*", or all keys)
Returns
a table of keys from the dynamic store.
​location​
Signature
hs.network.configuration:location() -> location
Type
Method
Description
Returns the current location identifier
Parameters
None
Returns
location - the UUID for the currently active network location
Notes
You can also retrieve this information as key-value pairs with hs.network.configuration:contents("Setup:")
If you have different locations defined in the Network preferences panel, this can be used to determine the currently active location.
​locations​
Signature
hs.network.configuration:locations() -> table
Type
Method
Description
Returns all configured locations
Parameters
None
Returns
a table of key-value pairs mapping location UUIDs to their names
​monitorKeys​
Signature
hs.network.configuration:monitorKeys([keys], [pattern]) -> storeObject
Type
Method
Description
Specify the key(s) or key pattern(s) to monitor for changes.
Parameters
keys - a string or table of strings containing the keys or patterns of keys, if pattern is true. Defaults to all keys.
pattern - a boolean indicating wether or not the string(s) provided are to be considered regular expression patterns (true) or literal strings to match (false). Defaults to false.
Returns
the store Object
Notes
if no parameters are provided, then all key-value pairs in the dynamic store are monitored for changes.
​proxies​
Signature
hs.network.configuration:proxies() -> table
Type
Method
Description
Returns information about the currently active proxies, if any
Parameters
None
Returns
a table of key-value pairs describing the current proxies in effect, both globally, and scoped to specific interfaces.
Notes
You can also retrieve this information as key-value pairs with hs.network.configuration:contents("State:/Network/Global/Proxies")
​setCallback​

Type
Method
Description
Set or remove the callback function for a store object
Parameters
a function or nil to set or remove the store object callback function
Returns
the store object
Notes
The callback function will be invoked each time a monitored key changes value and the callback function should accept two parameters: the storeObject itself, and an array of the keys which contain values that have changed.
This method just sets the callback function. You specify which keys to watch with hs.network.configuration:monitorKeys and start or stop the watcher with hs.network.configuration:start or hs.network.configuartion:stop​
