 1996-02-12 15:32:40 -03:00
Roberto Ierusalimschy 5a3a1fe458 debug interface functions to manipulated local variables: 
"lua_getlocal" and "lua_setlocal".
 1996-02-07 16:10:27 -02:00
Roberto Ierusalimschy 1431b52e76 improve of compiling error messages. 1996-02-05 11:26:01 -02:00
Roberto Ierusalimschy 2998049f51 local variable stack needs only the name of the variable (TreeNode); 
this way is simpler and faster than old way.
 1996-01-23 15:50:29 -02:00
Roberto Ierusalimschy 24ccc7c038 correction of some order dependencies in debug code. 1996-01-22 16:39:37 -02:00
Roberto Ierusalimschy 9d9f9c48ff local variables may appear inside blocks in main code. 1995-10-26 15:02:50 -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 39b071f7b1 new syntax for function declarations: "function a.x () ... " 
new semantics for function declarations: function f () is valid only
at run-time.
 1995-10-25 12:33:25 -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 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.
