An initial byte \xFF will ask for 7 continuation bytes, and then the
shift by (count * 5) will try to shift 35 bits.
Correction in utf8.offset2025-07-18T19:10:28+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-07-18T19:10:28+00:00urn:sha1:ccb8b307f11c7497e61f617b12f3a7f0a697256c
Wrong utf-8 character may have no continuation bytes.
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".
Collective declaration for globals ('global *')2025-05-13T14:43:10+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-05-13T14:43:10+00:00urn:sha1:3b9dd52be02fd43c598f4adb6fa7844e6a573923Details (typos in comments)2025-04-23T14:36:09+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-04-23T14:36:09+00:00urn:sha1:9b014d4bcd4ebadb523f1c1a1d38148d8526e5edRemoved copyright notice from 'testes/all.lua'2025-03-12T17:00:58+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-03-12T17:00:58+00:00urn:sha1:ab66652b3270b95222dea134b5e47bb3afc434cc
All test files refer to the main copyright notice in 'lua.h'.
utf8.offset returns also final position of character2024-05-27T14:29:39+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2024-05-27T14:29:39+00:00urn:sha1:814213b65fa4ab2b1a7216d06f68a6f3df89efcd
'utf8.offset' returns two values: the initial and the final position
of the given character.
More control over encoding of test files2023-08-17T13:42:56+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2023-08-17T13:42:56+00:00urn:sha1:f4211a5ea4e235ccfa8b8dfa46031c23e9e839e2
The few UTF-8 test files are commented as such, and there is only one
non UTF-8 test file (to test non UTF-8 sources).
Avoid excessive name pollution in test files2022-12-28T21:34:11+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2022-12-28T21:34:11+00:00urn:sha1:314745ed8438d1276c6c928d5f9d4be018dfadb6
Test files are more polite regarding the use of globals when locals
would do, and when globals are necessary deleting them after use.
