 Posted: Sun Oct 25, 2015 11:01 am Post subject: Redo ver. 1.05 (ALT+Backspace known from OllyDbg) |
 |
|
Lua script version 1.05
history: public release (1.02), increased number of "next lines" (1.03), deal with unreadable addresses (1.04), do not use "disassemblerview_onSelectionChange" (1.05)
CE will remember the original instruction, altered line will be moved to the right.
You can restore the old one with ALT+R.
After AA injection:
Manually altered line:
New menu entry:
| Code: | function restoreOrigBytes(sender)
selectedAddress_redo = disassemblerview_getSelectedAddress(redo_dv)
if origBytesTable[selectedAddress_redo]==nil then return end
local bytes={}
local start=origBytesTable[selectedAddress_redo].startaddress
local size=origBytesTable[selectedAddress_redo].size
--prepare subset
for i=1,size do bytes[#bytes+1]=origBytesTable[start+i-1].byte end
local script=string.format('%X',start)..':\r\n'..'db '..'#'..(table.concat(bytes,' #'))
skip_myAssemblerWithRedo=true
if not autoAssemble(script) then return nil end
skip_myAssemblerWithRedo=false
end
skip_myAssemblerWithRedo=false
function myAssemblerWithRedo(addr,inst)
if skip_myAssemblerWithRedo -- forced skip?
or
origBytesTable[addr]~=nil -- we already have collected orig bytes
then return nil end
local origsize=getInstructionSize(addr)
local sizes={}
local tmpVar=0
-- get sizes of those next lines
for i=1,20 do
sizes[i]=getInstructionSize(addr+tmpVar)
tmpVar=tmpVar+sizes[i]
end
--get bytes of those next lines
local originalbytes=readBytes(addr,tmpVar,true)
if originalbytes==nil then return nil end
-- save original bytes if not already saved
tmpVar=1
for i=1,20 do
for j=1,sizes[i] do
local tmp={startaddress=addr, byte=originalbytes[tmpVar], size=sizes[i]}
if not origBytesTable[addr+j-1] then origBytesTable[addr+j-1]=tmp end
tmpVar=tmpVar+1
end
addr=addr+sizes[i]
end
return nil
end
getVisibleDisassembler().OnDisassembleOverride =
function (vd, a, ldd)
if origBytesTable[a]==nil then return nil,nil end -- 100% not changed
disAsm_redo.syntaxhighlighting=vd.syntaxhighlighting
disAsm_redo.disassemble(a)
local modified=false
local startbyte=origBytesTable[a].startaddress
local endbyte=startbyte+origBytesTable[a].size-1
-- search for differences
for i=startbyte,endbyte do
if disAsm_redo.LastDisassembleData.bytes[i-origBytesTable[a].startaddress+1]~=
origBytesTable[i].byte
then modified=true break end
end
if not modified then return nil,nil end -- bytes the same, not modified
for k,v in pairs(disAsm_redo.LastDisassembleData) do ldd[k]=v end
ldd.opcode=' '..ldd.opcode -- add few spaces at the beginning
return ldd.opcode,ldd.description
end
function addRedoMenuItem()
redo_dv=getMemoryViewForm().DisassemblerView
if redoMenuItem==nil then
local pmenu=redo_dv.PopupMenu
redoMenuItem=createMenuItem(pmenu)
pmenu.Items.add(redoMenuItem)
end
redoMenuItem.Caption='Restore Original Bytes'
redoMenuItem.Shortcut='Alt+R'
redoMenuItem.OnClick=restoreOrigBytes
end
if myAssemblerWithRedo_ID==nil then myAssemblerWithRedo_ID=registerAssembler(myAssemblerWithRedo) end
if disAsm_redo==nil then disAsm_redo=createDisassembler() end
if origBytesTable==nil then origBytesTable={} end
addRedoMenuItem() |

It is more like CE plug-in, written in Lua.
It is an autorun Lua script.
Copy and paste above script into any/new lua file inside autorun folder.

| Should this script work when you manually change a bunch of bytes in the bottom half of the viewer? I would like to change a float in hex and then be able to undo it.
