Roberto Ierusalimschy 826d70fcba new type lua_Function for activation records 1996-02-08 15:03:20 -02:00
Roberto Ierusalimschy 5a3a1fe458 debug interface functions to manipulated local variables: 
"lua_getlocal" and "lua_setlocal".

Roberto Ierusalimschy f188e1000b useless "#include math.h" 1995-11-16 18:46:24 -02:00
Roberto Ierusalimschy 87fe07c0d4 little improvement 1995-11-10 12:12:02 -02:00
Roberto Ierusalimschy 15d48576ea functions now may be declared with any "var" as a name; 
therefore they do not have a "baptism" name.
Changes in debug API to acomodate that.
 1995-10-26 12:21:56 -02:00
Roberto Ierusalimschy 9efc257d9d new method to keep debug line information: current line is stored on the 
Lua stack, just below (new) base, with tag LUA_T_LINE.
SETLINE opcodes are generated by lex.
 1995-10-25 11:05:51 -02:00
Roberto Ierusalimschy a66404aca6 function "setfallback" now gives an error if called with wrong parameters. 1995-10-17 12:30:05 -02:00
Roberto Ierusalimschy d80659759b new module luadebug.h. 1995-10-17 12:12:45 -02:00
Roberto Ierusalimschy 2cffb08a5c new style for debug information about functions: no more SETFUNCTION 
opcodes. When a function is called, its entry in the stack is marked with
LUA_T_(C)MARK, so function 'luaD_stackedfunction' can find it if
needed.
Functions now have their file names in the headers, so there is no need
of 'addfile' and the like.
 1995-10-17 09:58:41 -02:00
Roberto Ierusalimschy b17c76817d new function "luaI_findconstantbyname". 1995-10-13 12:16:25 -03:00

Roberto Ierusalimschy 7e01348658 "docall" now assumes that called function is always on the stack, just 
below "base". That gives more regularity for the stack shape, and
prevents fallbacks of being garbage collected if they are redefined
during execution.

"lua_reportbug" is only an internal function to build debug information

Roberto Ierusalimschy df3a81ec88 functions that no more return error codes now have return type void 1994-12-28 10:55:47 -02:00
