Vararg functions with vararg tables don't use the arguments hidden in
the stack; therfore, it doesn't need to build/keep them.
New conceptual model for vararg2025-11-26T14:18:29+00:00Roberto Iroberto@inf.puc-rio.br2025-11-26T14:18:29+00:00urn:sha1:f33cc4ddec886ea499d7d41dd60cac5ddc5687db
Conceptually, all functions get their vararg arguments in a vararg
table. The storing of vararg arguments in the stack is always treated
as an optimization.

Comments, capitalization in the manual, globals in test 'heady.lua'

Initialization "global a = 10" raises an error if global 'a' is already
defined, that is, it has a non-nil value.
Vertical bar removed from syntax of vararg table2025-10-30T14:07:01+00:00Roberto Iroberto@inf.puc-rio.br2025-10-30T14:07:01+00:00urn:sha1:d342328e5b24c9b3c6c5b33bfcf9f8534210b8e6
The syntax 'function foo (a, b, ...arg)' is already used by JavaScript
for this same semantics, so it seems natural to use the same notation in
Lua.
Standard allocator function added to the API2025-10-17T16:53:35+00:00Roberto Iroberto@inf.puc-rio.br2025-10-17T16:53:35+00:00urn:sha1:b352217b8498a5ed8f6c954b3da365fcbb89751f
That makes easier to redefine luaL_newstate.
Optimization for vararg tables2025-09-24T21:33:08+00:00Roberto Iroberto@inf.puc-rio.br2025-09-24T21:33:08+00:00urn:sha1:25c54fe60e22d05cdfaa48c64372d354efa59547
A vararg table can be virtual. If the vararg table is used only as
a base in indexing expressions, the code does not need to create an
actual table for it. Instead, it compiles the indexing expressions
into direct accesses to the internal vararg data.
Better documentation for LUA_ERRERR2025-08-20T18:29:46+00:00Roberto Iroberto@inf.puc-rio.br2025-08-20T18:29:46+00:00urn:sha1:c345877e4c2588324d9a1e5655e8f48200ba2e5e
Not all errors in a message handler generate a LUA_ERRERR.
Functions 'frexp'-'ldexp' back to the math library2025-08-09T18:15:20+00:00Roberto Iroberto@inf.puc-rio.br2025-08-09T18:15:20+00:00urn:sha1:53dc5a3bbadac166a8b40904790f91b351e55dd9
They are basic for anything that handles the representation of
floating numbers.
