Say I have these two:

Code:

define(returnA,CryingSuns.Navigation:NavigationSystem:IsConnectedTo+5)
define(returnB,"CryingSuns.Navigation:NavigationSystem:IsConnectedTo"+5)
define(returnC,"CryingSuns.Navigation:NavigationSystem:IsConnectedTo+5")

B is the only one that works in autoassembler. I've written a lua function to safely handle addresses like these I think, I just wanted to make sure I wasn't missing something that already exists or an easier way...

Code:

function util.safeAddress(s)
local tbl = {}
for a in string.gmatch(s, "([^+]+)[+]?") do table.insert(tbl, a) end
local result = '"'..tbl[1]..'"'
if #tbl > 1 then result = result..'+'..tbl[2] end
return result
end

Just throwing it out there, would it be better if AA could accept addresses like this without quotes, or should the symbol handler return addresses like this surrounded by quotes by default?

i'm not sure why A wouldn't work , OpenProcess+8 works fine, and

Code:

define(bla,Bob:BobGetAxe+8)

bla:
nop
nop
nop

also works fine (mono symbol). Check out the mono symbolhandler override, perhaps your implementation is missing something

but yeah, the fully quoted line doesn't work, but quotes are really to distinguish symbols from offsets anyhow
example:

Code:

tutorial-i386.exe+13

this would be interpreted as the symbol tutorial minus the symbol i386.exe and add 13 to that (ok, it automatically tries "tutorial-i386.exe"+13 after figuring out tutorial doesn't exist, but that works by adding quotes itself, not removing)

Code:

"tutorial-i386.exe"+13

this will be interpreted as the symbol tutorial-i386.exe and add 13 to that

but

Code:

"tutorial-i386.exe+13"

would be interpreted as the symbol named "tutorial-i386.exe+13"

and that one doesn't exist
