- LUAMOD_API defined as 'extern "C"' in C++.
- "ANSI C" is in fact "ISO C" (comments)
- Removed option -std from makefile in testes/libs. (Easier to change
to C++ for tests).
Warning in loslib.c (signed-unsigned comparison)2025-06-27T17:47:11+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-06-27T17:47:11+00:00urn:sha1:cfce6f4b20afe85ede2182b3df3ab2bfcdb0e692Added gcc option '-Wconversion'2024-07-27T16:32:59+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2024-07-27T16:32:59+00:00urn:sha1:0acd55898d0aaae8dbc14c8a1bc1e3bdffc8701b
No warnings for standard numerical types. Still pending alternative
numerical types.
llimits.h being used by all Lua code2024-06-20T17:46:06+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2024-06-20T17:46:06+00:00urn:sha1:a08d82eb132bfd9db5b91e0d5ebcb81d7b26dcd0
The definitions in llimits.h are useful not only for the core. That
header only defines types and '#define's, so libs and core still do
not share any real code/data.
More disciplined use of 'errno'2024-06-12T18:50:31+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2024-06-12T18:50:31+00:00urn:sha1:bb7bb5944c9b3c868c6ab9cbe7d11b611251066b
Set errno to zero before calling any function where we may use its
errno, and check errno for zero before using it (as functions may not
set it even in error). The code assumes that no function will put
garbage on errno (although ISO C allows that): If any function during an
operation set errno, and the operation result in an error, assume that
errno has something to say.
Simpler definition for LUA_STRFTIMEOPTIONS2023-02-07T13:48:39+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2023-02-07T13:48:39+00:00urn:sha1:5e08b41567c5723c9f599d02a7511aa398f7c646
There is no need for those intermediate definitions.
New macro LUA_USE_IOS2023-02-02T16:43:41+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2023-02-02T16:43:41+00:00urn:sha1:cf08915d62e338c987b71c078b148490510e9fe7
Do not try to detect automatically whether system is iOS; it is
simpler and more reliable to let the programmer inform that.
Fix absence of 'system' in iOS2023-01-24T18:04:17+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2023-01-24T18:04:17+00:00urn:sha1:d69789da1ccfa4db7c241de6b471d6b729f1561e
Despite claiming to be ISO, the C library in some Apple platforms
does not implement 'system'.
Small simplification in overflow check in 'getfield'2022-09-23T13:57:35+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2022-09-23T13:57:35+00:00urn:sha1:cfbe378f906061ee56f91acfbdf569d0d3fb9556
Subtracting a small non-negative int from a non-negative int cannot
overflow, and adding a non-negative int to INT_MIN cannot overflow.
Broadening the use of branch hints2021-02-24T14:14:44+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2021-02-24T14:14:44+00:00urn:sha1:59c88f846d1dcd901a4420651aedf27816618923
More uses of macros 'likely'/'unlikely' (renamed to
'l_likely'/'l_unlikely'), both in range (extended to the
libraries) and in scope (extended to hooks, stack growth).
