Initialization "global a = 10" raises an error if global 'a' is already
defined, that is, it has a non-nil value.
Fixed initialization of global variables2025-10-29T16:14:48+00:00Roberto Iroberto@inf.puc-rio.br2025-10-29T16:14:48+00:00urn:sha1:d4eff00234dc55dac4cb86b6187f5607c1254f9b
When calling 'luaK_storevar', the 'expdesc' for the variable must be
created before the one for the expression, to satisfy the assumptions
for register allocation. So, in a statement like 'global a = exp', where
'a' is actually '_ENV.a', this variable must be handled before the
initializing expression 'exp'.
Optional initialization for global declarations2025-07-08T16:33:57+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-07-08T16:33:57+00:00urn:sha1:942c10a5e33811a08a290ec15031c950a6d17c99No need to limit variable declarations to 2502025-06-18T19:45:55+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-06-18T19:45:55+00:00urn:sha1:07b009c3712c062957593d0a4fa82e0fe9023024
Only local variables, which use registers, need this low limit.
New way to control preambular declaration2025-05-20T20:36:05+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-05-20T20:36:05+00:00urn:sha1:be05c444818989463dc307eed283503d391f93eb
Validity of the preambular global declaration in controled together
with all declarations, when checking variable names.
Proper error message when jumping into 'global *'2025-05-18T15:03:54+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-05-18T15:03:54+00:00urn:sha1:6d53701c7a0dc4736d824fd891ee6f22265d0d68
A goto cannot jump into the scope of any variable declaration,
including 'global *'. To report the error, it needs a "name" for
the scope it is entering.
Variable attributes can prefix name list2025-05-18T14:43:43+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-05-18T14:43:43+00:00urn:sha1:abbae57c7844b1121e7251d56f681394f20c1821
In this format, the attribute applies to all names in the list;
e.g. "global<const> print, require, math".
