namespace - Open a namespace
/name namespace ...your.code... end -> -
/myspace namespace % this opens namespace "myspace"
/var 23 def % this creates the variable "myspace::var"
/func {(This is stupid.) =} def % this creates the function "myspace::func"
end % this closes the namespace "myspace"
/myspace namespace % this re-opens the namespace "myspace"
who % this shows the variables defined in the namespace
end % this closes the namespace "myspace"
myspace /func call % this calls "myspace::func"
"namespace" provides to SLI the concept of namespaces,
as known from C++.
The command changes the current scope to the namespace of the given
name, i.e.,
• all following symbol definitions go to this namespace
• all symbols that were previously defined in this namespace become
known
The namespace must be closed by an "end" statement.
The symbols defined in a namespace persist across closing and
re-opening of the namespace. Namespaces can be nested.
For alternative ways of accessing a namespace,
see "using" and "call".
/name - the namespace to open
If the named object is not a dictionary, TypeMismatchError is raised.
Currently, namespaces are implemented as
dictionaries. Namespaces may become more tightly
integrated with the SLI interpreter in future.
The idea is to define a set of symbols not in the global user
dictionary, but in a separate dictionary that has the name of the
namespace. Thus, symbols in different namespaces can have
identical names, and are effectively disambiguated by the current
dictionary context.
Note that the namespace dictionary is looked up and created in the
current scope. This is to allow for nested namespaces.
