Trying to find out why my handler doesn’t add “Header-Blank” to the text string
set mySectionHeaderPref to "all blank"
set myBigOrderList to "a
b
c
d
"
--
--
addHeader(mySectionHeaderPref, myBigOrderList)
--
--
set myBigOrderList to myBigOrderList & "End"
--
--
on addHeader(mySectionHeaderPref, myBigOrderList)
local mySectionHeaderPref, myBigOrderList
--
if mySectionHeaderPref is equal to "all blank" then
set myBigOrderList to myBigOrderList & "Header-Blank" & linefeed
end if
end addHeader
It a scope question and the answer is actually in your code.
Explicit
local mySectionHeaderPref, myBigOrderList
– which is redundant by the way – declares myBigOrderList as (new) local variable in the scope of the handler which is different from the variable myBigOrderList in the implicit run handler.
You have a few options:
Remove the second parameter and declare myBigOrderList in the handler as global.
on addHeader(sectionHeaderPref)
global myBigOrderList
if sectionHeaderPref is equal to "all blank" then
set myBigOrderList to myBigOrderList & "Header-Blank" & linefeed
end if
end addHeader
Declare the outer myBigOrderList as property
property myBigOrderList : "a
b
c
d
"
...
on addHeader(sectionHeaderPref)
if sectionHeaderPref is equal to "all blank" then
set myBigOrderList to myBigOrderList & "Header-Blank" & linefeed
end if
end addHeader
Return the value and assign it back.
set myBigOrderList to addHeader(mySectionHeaderPref, myBigOrderList)
...
on addHeader(mySectionHeaderPref, myBigOrderList)
-- in the handler myBigOrderList is a local variable, it's a different object as the variable in the run handler
if mySectionHeaderPref is equal to "all blank" then
set myBigOrderList to myBigOrderList & "Header-Blank" & linefeed
end if
return myBigOrderList
end addHeader
