1. structures are possible
------=_NextPart_000_01BE3EE1.5D27B680
I know how to implement structures using Euphoria.
I would like to know others opinion on names for the following routines.
my suggestion: struct()
create_a_struct("customer", {{"name", "age", "sex"},
{"sequence", "integer", "sequence"}})
my suggestion: init_var()
create_a_variable("a_record", "customer")
create_a_variable({"s1", "s2"}, "customer")
my suggestion: assign()
assign_a_value("a_record.name", "Bob Jones")
assign_a_value("a_record.age", 44)
assign_a_value("a_record.sex", "male")
assign_a_value("s1", {"Mary Hyde", 24, "female"})
assign_a_value("s2", {"Sarah Hamill", 36, "female"})
my_suggestion: value_of()
object x, x2
x = get_value_of("s1.age")--x = 24
x2 = get_value_of("s2") --x2 = {"Sarah Hamill", 36, "female"}
my suggestion: del_var()
delete_var("x2")
assign_a_value("x2.name", "Harry")-- an assignment to x2 is now illegal.
--because it has been removed from the variable stack.
--This isn't neccessary for cleanup but it can be used to conserve
--memory when you know that this won't be used again.

2. structures are possible
Also, Type checking will bill possible using the routines that I
create.

Partial structure code already exist.
I have partially created my struct.e library file. It does not as of yet
handle type_checking.
It also has not yet been speed optimized. The speed optimizing will
require some additional
routines. I fully intend to complete this library. The routine names are
subject to change
according to whatever naming suggestions I recieve. I want these routines
to be fully
accepted by all those that are interested in structures in the programming.
I am trying
to make use of the routines as simple as possible and plan to make the
routines as flexible
as I possibly can. Example: You can assign an entire structure a sequence.
It may not
be speed optimized when finished because of the requirement of
type_checking every
element in the sequence. I am still pondering how to detect whether
type_checking is on
or not. If I am unable to detect I will be force to create additional
routines to instruct the
struct.e library to disable or enable it's type_checking. Default will be
SLOW enabled.
Another example of the flexibilty is you can also recieve an entire
structure.
IE: say you have cat subdivided as cat.name, cat.birthyear, cat.sex
you can retrieve either cat.name seperately or part of the entire cat
structure.
Example:
assign("cat.name", "Fluffy")
assign("cat.birthyear", 1998)
assign("cat.sex", "Female")
Assuming that you initialized cat with a structure of {"name", "birthyear",
"sex"}
you will be able to get the value_of cat in either of two ways.
? value_of("cat.birthyear") -- this prints 1998
or
? value_of("cat") -- this prints {{70,117,102,102,121},1998,
{70,101,109,97,108,101}}
BTW, {70,117,102,102,121} = "Fluffy" and {70,101,109,97,108,101} = "Female"
NOTE: value_of() will not be subject to type_check ing. for obvious
reasons. You are only
getting data. However assign() will be subject to type_check ing. In fact
assign() will be the
only routine that does the type_checking.
CODE is attached Below.
