nameSpace copy
Namespace commands
Synopsis
nameSpace copy {filter} {from | to} {local | global} {namespace name}
Description
(Added in 1.40) The Namespace copy command allows to copy all or part of variables within a Namespace into another. The {filter} parameter is use to specify which variables should be copied and accepts two special characters "?" and "*".
The "?" character matches any single character and can be use multiple times within one {filter} expression. I.e. "return?" will match any variable whose name start with "return" and has one additional character.
The "*" character matches zero or more unspecified character. It can only appear but once within a {filter} expression. I.e. "return*" will match any variable whose name start with "return".
The {from | to} parameter defines the direction for the copy, while the {local | global} {namespace name} parameters define the name and scope of the Namespace to be used.
From: copies variables from the specified Namespace into the current Namespace.
To: copies variables from the current Namespace into the specified Namespace. If the specified Namespace doesn't exist at this time, it will be created.
The default Namespace is local and named STD. This setting is restored when the script is stopped.
Note: Currently only Local scope is available. Global scope is to be introduced in a future version of EasyUO.
Example
set !return ; make sure !return is empty gosub test display ok !return halt sub test nameSpace Push ; saves current namespace nameSpace Local Test ; create a new temporary namespace to work with set !return this_is_a_test nameSpace Pop ; restore previous namespace nameSpace Copy ret* From Local Test ; copy variables to the original namespace nameSpace Push ; saves current namespace nameSpace Local Test nameSpace Clear ; free memory used by temporary namespace nameSpace Pop ; restore previous namespace return
