* DetailsRoberto Ierusalimschy2019-06-031-9/+9
| | | | | Several small changes from feedback on 5.4 alhpa rc1 (warnings, typos in the manual, and the like)
* DetailsRoberto Ierusalimschy2019-05-281-2/+2
| | | | | | | - new error message for "attempt to assign to const variable" - note in the manual about compatibility options - comments - small changes in 'read_line' and 'pushstr'
* A few more improvements in 'luaO_pushvfstring'Roberto Ierusalimschy2019-05-031-29/+37
| | | | | | | | - 'L' added to the 'BuffFS' structure - '%c' does not handle control characters (it is not its business. This now is done by the lexer, who is the one in charge of that kind of errors.) - avoid the direct use of 'l_sprintf' in the Lua kernel
* Some more small improvements to 'luaO_pushvfstring'Roberto Ierusalimschy2019-04-261-54/+68
| | | | | | | Details: - counter 'pushed' moved to the struct 'BuffFS' - new auxiliar function 'getbuff' to build strings directly on the buffer.
* Revamp of 'lua_pushfstring' / 'luaO_pushvfstring'Roberto Ierusalimschy2019-04-241-37/+107
| | | | | | | | | The function 'luaO_pushvfstring' now uses an internal buffer to concatenate small strings, instead of pushing all pieces on the stack. This avoids the creation of several small Lua strings for each piece of the result. (For instance, a format like "n: '%d'" used to create three intermediate strings: "n: '", the numeral, and "'". Now it creates none.)
* Added field 'srclen' to structure 'lua_Debug'Roberto Ierusalimschy2019-04-041-15/+12
| | | | | | This new field gets the length of 'source' in the same structure. Unlike the other strings in that structure, 'source' can be relatively large, and Lua already has its length readily available.
* Changes in the validation of UTF-8Roberto Ierusalimschy2019-03-151-3/+3
| | | | | | | | | | | All UTF-8 encoding functionality (including the escape sequence '\u') accepts all values from the original UTF-8 specification (with sequences of up to six bytes). By default, the decoding functions in the UTF-8 library do not accept invalid Unicode code points, such as surrogates. A new parameter 'nonstrict' makes them accept all code points up to (2^31)-1, as in the original UTF-8 specification.
* New macros for arithmetic/bitwise operations in 'luaV_execute'Roberto Ierusalimschy2018-11-051-1/+1
| | | | | | | The repetitive code of the arithmetic and bitwise operators in the main iterpreter loop was moved to appropriate macros. (As a detail, the function 'luaV_div' was renamed 'luaV_idiv', as it does an "integer division" (floor division).
* Corrections in the implementation of '%' for floats.Roberto Ierusalimschy2018-08-281-5/+1
| | | | | | | | | The multiplication (m*b) used to test whether 'm' is non-zero and 'm' and 'b' have different signs can underflow for very small numbers, giving a wrong result. The use of explicit comparisons solves this problem. This commit also adds several new tests for '%' (both for floats and for integers) to exercise more corner cases, such as very large and very small values.
* Removed extra information from RCS keyword stringsRoberto Ierusalimschy2018-08-231-1/+1
| | | | | Version numbers and dates (mostly wrong) from RCS keyword strings removed from all source files; only the file name are kept.
* no more 'luaO_nilobject' to avoid comparison of global variable addressesRoberto Ierusalimschy2018-06-011-5/+1
| | | | (now uses static variables)
* 'luaO_pushvfstring' does not need to reallocate stackRoberto Ierusalimschy2018-04-251-10/+12
