Here's a further method. If you use some internal naming convention for your
global variables, all what you need is:
on clearGlobalsSelective()
repeat with g = 1 to the globals.count()
if not ("u" = chars(string(the globals.getPropAt(g)), 1, 1)) then the globals[g] =
VOID
end repeat
end
The naming convention used here as an example is really simple: you name your
globals at your will, but the ones you want preserved from being cleared are
to be prefixed by a "u", that stands for "unclearable". For example, let's take
these two sets of globals:
global giggle, mumble, titter, roarr, gurgle, gulp, help, swish, slam, gasp, pant
global uGiggle, uMumble, uRoarr, uGulp, uPant, uOffTopic
Some of them are initialized in startMovie, or in whichever else place and time,
while others aren't:
on startMovie
uGiggle = "..gigglin:)..gigglin:).."
uMumble = "mumblemumble..."
uTitter = ":())) :()) ( :)( :)(( :)((( :)()()("
uRoarr = "RRRRRROAR"
uGulp = "GULP!!!"
uPant = 100100100100
mumble = uMumble
roarr = uRoarr
gulp = uGulp
help = "...HHHHHELP!!!"
swish = "((< >))----->======>>>>>>>>"
slam = "[ [ [ [ [[[]~***"
pant = uPant
uOffTopic = [#no: 1, #lions: 2, #herein: 3]
end
Run clearGlobalsSelective()in the message window:
-- Welcome to Director --
showglobals
-- Global Variables --
uGULP = "GULP!!!"
uGiggle = "..gigglin:)..gigglin:).."
uPant = 100100100100
uMumble = "mumblemumble..."
uRoarr = "RRRRRROAR"
uOffTopic = [#no: 1, #lions: 2, #herein: 3]
The unprefixed globals aren't listed because showglobals doesn't show void globals.
There's more. If you wanted to init your globals to a some value of specific intrinsic
type, you could do it by a prefix using two characters or more. For example, with a
two-chars prefix:
on initGlobalsHyperSelective()
repeat with g = 1 to the globals.count()
px = chars(string(the globals.getPropAt(g)), 1, 2) -- px is for prefix
case 1 of
(px = "uI") : the globals[g] = 0 -- integer
(px = "uF") : the globals[g] = 0.0 -- float
(px = "uC") : the globals[g] = EMPTY -- string of characters
(px = "uL") : the globals[g] = list() -- linear list
(px = "uP") : the globals[g] = [:] -- property list
-- and so on..
otherwise
the globals[g] = VOID
end case
end repeat
end
The use of a "u" could seem reduntant in this case. It depends on how things are
organized. Please note I didn't tested this last handler.
Hope this helps,
