Module example Test

[Frank Brübach]

hello charles, can you check this module example, if that's running for you with latest update?

module

namespace cons
uses console
end namespace
end module

  % vcprint  ..cons..output
  % vcwait   ..cons..getkey

vcprint 12345678 vtab "hello steve jobs" vtab
vcprint "thank you for apple computers"
vcwait

Hi Frank,

OxygenBasic now reverts to using double colons again, since it is the standard for C languages, FreeBasic etc.

But invoking macros from outside the namespace is going to cause problems. So I suggest reopening the namespace.

module
======
namespace con
uses console
end namespace
end module

con::output "hello steve jobs" tab
con::output "thank you for apple computers" cr
con::getkey

'reopen namespace to use the macros:
namespace con
print "hello steve jobs" tab
print "thank you for apple computers" cr
wait
end namespace

hello charles, so far I have understood.. prefixes aren't working in old ways anymore?
for example: $ client ... and % vcprint  ..con..output

' doesnt work anymore this way
' % vcprint  ..con..output
' % vtab     ..con..tab
' vcprint 12345678 vtab "hello steve jobs" vtab
' vcprint "hello franko"
' doesnt work anymore

solution: con::output "hello steve jobs" tab

'reopen namespace to use the macros:
namespace con
print "hello steve jobs" tab 12345678 cr
print "thank you for apple computers" cr
wait
end namespace

ok here I have noticed... thanks

question: how looks the new structure for namespace in general?
but that's not so clever to use print messages at the end again?

module
namespace x
uses console ' (for example)
end namespace
end module

x:: output "hello steve" tab

namespace x
print "hello steve" tab 123456 cr ' again, why?
wait
end namespace


2) next example how to make prefixes now run with $ client ... ?

Code Select Expand

'with macro prefixes
'Accessing parent / client symbols
'
$ client ... ' prefixes arent running ok
int x=0
print client.x '0
namespace aa
  int x=2
  print client.x '0
  namespace bb
    int x=4
    print client.x '2
    namespace cc
      int x=6
      print client.x '4
    end namespace
    'print ..cc..x '6
  end namespace
end namespace

print "ok"


thanks, frank

That won't work any more, but nested namespaces are still supported:

Code Select Expand

int i=0
namespace  aa
  int i=1
  namespace bb
    int i=2
  end namespace 'bb
end namespace 'aa

print i '0
print aa::i '1
print aa::bb::i '2

Another feature of the new nested namespaces is automatic access to the parent namespace, without using a prefix.

Code Select Expand

namespace  aa
  int k=10
  namespace bb
    int i=1
    print k+i '11
  end namespace 'bb
end namespace 'aa
