Next revision of my previous script adds support for those:
- [sym1+100]+[sym2]*[sym3]
- [sym1+sym4*10]+[sym2]*[sym3]
and nested pointers, i.e. pointer used as offset (or base) for another pointer:
- [sym1+[sym4]*10]+[sym2]*[sym3]
- [[sym1+[sym4]*10]+[sym2]*[sym3]]
revision 2:
| Code: | skipMoreAdvancedLookup=false
function moreAdvancedLookup(s)
if skipMoreAdvancedLookup then return nil end
if s=='' then return end
local copyofs,result=s
for out in s:gmatch('%b[]') do
local address = string.format('%x',(readPointer(out:sub(2,-2)) or 0))
local out2=out:gsub('[.*+%%[-]','%%%1') -- escape more chars, forgot about it in rev1
copyofs=copyofs:gsub(out2,address)
end
skipMoreAdvancedLookup=true
local errorOnLookupFailureOldState=errorOnLookupFailure(false)
result=getAddress(copyofs)
errorOnLookupFailure(errorOnLookupFailureOldState)
skipMoreAdvancedLookup=false
return result
end
if moreAdvancedLookupID~=nil then unregisterSymbolLookupCallback(moreAdvancedLookupID) end
moreAdvancedLookupID = registerSymbolLookupCallback(moreAdvancedLookup, slNotInt) |
Because it allows nested pointers it is much slower.
If you don't need nested pointers support, use this instead:
| Code: | skipMoreAdvancedLookup=false
function moreAdvancedLookup(s)
if skipMoreAdvancedLookup then return nil end
if s=='' then return end
local copyofs,result=s
skipMoreAdvancedLookup=true
for out in s:gmatch('%b[]') do
local address = string.format('%x',(readPointer(out:sub(2,-2)) or 0))
local out2=out:gsub('[.*+%%[-]','%%%1') -- escape more chars, forgot about it in rev1
copyofs=copyofs:gsub(out2,address)
end
--skipMoreAdvancedLookup=true
local errorOnLookupFailureOldState=errorOnLookupFailure(false)
result=getAddress(copyofs)
errorOnLookupFailure(errorOnLookupFailureOldState)
skipMoreAdvancedLookup=false
return result
end
if moreAdvancedLookupID~=nil then unregisterSymbolLookupCallback(moreAdvancedLookupID) end
moreAdvancedLookupID = registerSymbolLookupCallback(moreAdvancedLookup, slNotInt) |
Edit:
forgot local for errorOnLookupFailureOldState variable
Edit2:
readPointer instead of readInteger
