Re: printing function name in luac/print.c?

[Jeroen Janssen <japj@...>]

btw... looking at the (luac) listing of life.lua I have some question

* is there an opcode list that describes the parameters "passed" to
opcodes? + what each opcode does?

listing
=======
main <@life.lua:0> (146 instructions/584 bytes at 002F3868)
0 params, 26 stack positions, 0 locals, 19 strings, 0 numbers, 7
functions
     1    PUSHSTRING   1	; *
     2    SETGLOBAL    0	; ALIVE
     3    PUSHSTRING   3	; .
     4    SETGLOBAL    2	; DEAD
     5    CLOSURE      0 0	; 002F3A70
     6    SETGLOBAL    4	; delay
     7    CLOSURE      1 0	; 002F3E88
     8    SETGLOBAL    5	; ARRAY2D
     9    CREATETABLE  0
    10    SETGLOBAL    6	; _CELLS
    11    GETGLOBAL    6	; _CELLS
    12    PUSHSTRING   7	; spawn
    13    CLOSURE      2 0	; 002F4430
    14    SETTABLE     3 3
    15    GETGLOBAL    6	; _CELLS
    16    PUSHSTRING   8	; evolve
    17    CLOSURE      3 0	; 002F4148
    18    SETTABLE     3 3
    19    GETGLOBAL    6	; _CELLS
    20    PUSHSTRING   9	; draw
    21    CLOSURE      4 0	; 002F3BD8
    22    SETTABLE     3 3
    23    CLOSURE      5 0	; 002F5410
    24    SETGLOBAL    10	; CELLS

   140    CLOSURE      6 0	; 002F5E98
   141    SETGLOBAL    18	; LIFE
   142    GETGLOBAL    18	; LIFE
   143    PUSHINT      40
   144    PUSHINT      20
   145    CALL         0 0
   146    END          

* The number after CLOSURE tells the function number (local to this
function) in the source file (0 being the first (delay), and 6 being
LIFE)?
* SETTABLE sets an item of a table (_CELLS:spawn , evolve and draw
functions), are those functions "appended" to the list? (thus the order
of SETTABLE determines what should be used with GETDOTTED and
GETINDEXED?)

function <@life.lua:78> (22 instructions/88 bytes at 002F5410)
2 params, 7 stack positions, 3 locals, 5 strings, 0 numbers, 0 functions
     1    GETGLOBAL    0	; ARRAY2D
     2    GETLOCAL     0	; w
     3    GETLOCAL     1	; h
     4    CALL         2 1
     5    GETLOCAL     2	; c
     6    PUSHSTRING   1	; spawn
     7    GETGLOBAL    2	; _CELLS
     8    GETDOTTED    1	; spawn
     9    SETTABLE     3 3
    10    GETLOCAL     2	; c
    11    PUSHSTRING   3	; evolve
    12    GETGLOBAL    2	; _CELLS
    13    GETDOTTED    3	; evolve
    14    SETTABLE     3 3
    15    GETLOCAL     2	; c
    16    PUSHSTRING   4	; draw
    17    GETGLOBAL    2	; _CELLS
    18    GETDOTTED    4	; draw
    19    SETTABLE     3 3
    20    GETLOCAL     2	; c
    21    RETURN       3
    22    END          

* In the main SETGLOBAL 0 sets ALIVE to "*". in CELLS(w,h) - function at
line 78 - GETGLOBAL 0 returns ARRAY2D? This looks wrong (since ARRAY2D
is global 5?)
