Author	SHA1	Message	Date
Roberto Ierusalimschy	fb172d0a92	No need for 'volatile' in string.pack/unpack Type punning an address to 'char *' should be always safe.	4 years ago
Roberto Ierusalimschy	f83de8e34e	Wrong cast in 'str_unpack'	4 years ago
Roberto Ierusalimschy	513559cc47	Fixed bug in 'string.format("%p")' The string "(null)" used for non-collectable values must be printed as a string, not as a pointer. (Bug introduced in commit `e0cbaa50fa`).	5 years ago
Roberto Ierusalimschy	92594f0939	Corrected direct use of 'snprintf' in 'lstrlib.c'	5 years ago
Roberto Ierusalimschy	e0cbaa50fa	Added test for NULL in string.format("%p") ISO C states that standard library functions should not be called with NULL arguments, unless stated otherwise. 'sprintf' does not state otherwise, and it doesn't hurt to be on the safe side.	5 years ago
Roberto Ierusalimschy	2d92102dee	'l_mathlim' renamed to 'l_floatatt' That macro is applied to float attributes, not to limits.	5 years ago
Roberto Ierusalimschy	6e285e5392	More pious implementation of 'string.dump' In 'str__dump', the call to 'lua_dump' assumes the function is on the top of the stack, but the manual allows 'luaL_buffinit' to push stuff on the stack (although the current implementation does not). So, the call to 'luaL_buffinit' must come after the call to 'lua_dump'.	5 years ago
Roberto Ierusalimschy	6055a039b5	Easy redefinition of valid flags for 'string.format'	5 years ago
Roberto Ierusalimschy	6a84c32900	No coercion string->number in arithmetic with LUA_NOCVTS2N	5 years ago
Roberto Ierusalimschy	b96b0b5abb	Added macro 'luaL_pushfail' The macro 'luaL_pushfail' documents all places in the standard libraries that return nil to signal some kind of failure. It is defined as 'lua_pushnil'. The manual also got a notation (@fail) to document those returns. The tests were changed to be agnostic regarding whether 'fail' is 'nil' or 'false'.	5 years ago
Roberto Ierusalimschy	7f5c31cdca	Fixed bug in 'string.format' with option '%f' As an example, 'print(string.format("%.99f", 1e70))' may have a lot of garbage after the number. The old test to ensure that 'string.format("%.99f", n)' was not too large, 'fabs(n) < 1e100', assumes that the number will fit in the 99 bytes; but the 99 is not the space for the number, it is the added extra zeros. The option worked for smaller numbers because of the extra space added to MAX_ITEM.	5 years ago
Roberto Ierusalimschy	2d3f095448	Avoid using large buffers in 'string.format' The result of "string.format("%.99f", -1e308) is 410 characters long, but all other formats have much smaller limits (at most 99 plus a fex extras). This commit avoids 'string.format' asking for a buffer ~400 chars large when ~100 will do.	6 years ago
Roberto Ierusalimschy	b0810c51c3	Small optimizations in 'string.gsub' Avoid creating extra strings when possible: - avoid creating new resulting string when subject was not modified (instead, return the subject itself); - avoid creating strings representing the captured substrings when handling replacements like '%1' (instead, add the substring directly to the buffer).	6 years ago
Roberto Ierusalimschy	dfebe439db	New conversion specifier '%p' for 'string.format' The call 'string.format("%p", val)' gives a Lua equivalent to the C API function 'lua_topointer'.	6 years ago
Roberto Ierusalimschy	cf71a5ddc7	Details Several small improvements (code style, warnings, comments, more tests), in particular: - 'lua_topointer' extended to handle strings - raises an error in 'string.format("%10q")' ('%q' with modifiers) - in the manual for 'string.format', the term "option" replaced by "conversion specifier" (the term used by the C standard)	6 years ago
Roberto Ierusalimschy	264659bd53	Optional 'init' argument to 'string.gmatch' The function 'string.gmatch' now has an optional 'init' argument, similar to 'string.find' and 'string.match'. Moreover, there was some reorganization in the manipulation of indices in the string library. This commit also includes small janitorial work in the manual and in comments in the interpreter loop.	6 years ago
Roberto Ierusalimschy	da37ac9c78	Detail Slightly better error message for invalid conversions in 'string.format'.	6 years ago
Roberto Ierusalimschy	46beca5bed	Better error messages for some polymorphic functions New auxiliary functions/macros 'luaL_argexpected'/'luaL_typeerror' ease the creation of error messages such as bad argument #2 to 'setmetatable' (nil or table expected, got boolean) (The novelty being the "got boolean" part...)	6 years ago
Roberto Ierusalimschy	f99509581e	Removed extra information from RCS keyword strings Version numbers and dates (mostly wrong) from RCS keyword strings removed from all source files; only the file name are kept.	6 years ago
