* DetailsRoberto Ierusalimschy2019-08-011-7/+13
| | | | | - removed rule about RCS from makefile - comments and nitpicking in 'llex.c'
* DetailsRoberto Ierusalimschy2019-06-031-2/+2
| | | | | Several small changes from feedback on 5.4 alhpa rc1 (warnings, typos in the manual, and the like)
* A few more improvements in 'luaO_pushvfstring'Roberto Ierusalimschy2019-05-031-1/+4
| | | | | | | | - '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
* Syntax should not allow numbers touching identifiersRoberto Ierusalimschy2019-04-091-0/+2
| | | | Code like 'a = 1print()' should not be accepted.
* Fixed small bugs/issuesRoberto Ierusalimschy2019-03-251-1/+1
| | | | | | | | | | | | | - In 'readutf8esc' (llex.c), the overflow check must be done before shifting the accumulator. It was working because tests were using 64-bit longs. Failed with 32-bit longs. - In OP_FORPREP (lvm.c), avoid negating an unsigned value. Visual Studio gives a warning for that operation, despite being well defined in ISO C. - In 'luaV_execute' (lvm.c), 'cond' can be defined only when needed, like all other variables.
* Changes in the validation of UTF-8Roberto Ierusalimschy2019-03-151-1/+1
| | | | | | | | | | | 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.
* Bug: Long brackets with a huge number of '=' causes overflowRoberto Ierusalimschy2018-12-141-14/+16
| | | | | | | A long bracket with too many equal signs can overflow the 'int' used for the counting and some arithmetic done on the value. Changing the counter to 'size_t' avoids that. (Because what is counted goes to a buffer, an overflow in the counter will first raise a buffer-overflow error.)
* 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 nil-in-tableRoberto Ierusalimschy2018-04-041-2/+2
|
* new experimental syntax using reserved word 'undef'Roberto Ierusalimschy2018-03-071-2/+2
|
* first version of empty entries in tablesRoberto Ierusalimschy2018-02-231-2/+2
| | | | (so that, in the future, tables can contain regular nil entries)

|
* new type 'StackValue' for stack elementsRoberto Ierusalimschy2017-06-291-2/+2

* in hash nodes, keys are stored in separate pieces to avoid wastingRoberto Ierusalimschy2017-06-091-3/+3
| | | | space with alignments
* now that 'luaO_str2num' always accepts a dot as a radix character,Roberto Ierusalimschy2016-05-021-33/+2
| | | | the lexer does not need to bother with this issue.
* details (typos in comments)Roberto Ierusalimschy2015-11-191-2/+2

* type 'TString' refers directly to the structure inside the unionRoberto Ierusalimschy2014-07-181-6/+6

* 'luaO_str2d' + 'luaO_str2int' replaced by 'luaO_str2num' (which convertsRoberto Ierusalimschy2014-04-301-27/+25
