Hi,
I'd like to more easily define user symbols.
Currently I have to right click an instruction -> copy to clipboard -> addresses only
then : view -> userdefined symbol or (ctrl+u)
in the dialog, paste the address and write my symbol name
then click the add symbol button.
I'd like the procedure to be easier, something like hitting F2 on the keyboard while the instruction is highlighted, type the symbol name then hit enter
Or a menu under the context menu of an instruction with
a simple dialog box just like (set change comment / header)
doing this will help with debugging and naming of known (reversed functions)

You could write a lua module for the autorun folder that adds to the context menu.
Here's one I use to add a "Copy Address" option.
pluginAddCopyAddressMemoryView.lua:
| Code: |
local t = translate
local format = string.format
if MainForm == nil then
MainForm = getMainForm()
end
if AddressList == nil then
AddressList = getAddressList()
end
local function getPointerSize()
aasStr = [====[
globalAlloc(memPointerTest, 0x8)
memPointerTest:
db FF FF FF FF FF FF FF FF
]====]
local assembled = autoAssemble(aasStr)
if assembled then
local p1 = readQword('memPointerTest')
local p2 = readPointer('memPointerTest')
if p1 == p2 then
return 0x8
else
return 0x4
end
end
return nil
end
local function getPointerSizeStrs()
local pointerSize = getPointerSize()
local pointerSizeStr = format('0x%X', pointerSize or 0x8)
local pointerFtmStr = '%016X'
local pointerWordSize = 'dq'
local pointerDefaultStr = 'dq 0'
if pointerSize == 0x4 then
pointerFtmStr = '%08X'
pointerWordSize = 'dd'
pointerDefaultStr = 'dd 0'
end
return pointerSize, pointerSizeStr, pointerFtmStr, pointerWordSize, pointerDefaultStr
end
local function getModuleFromAddress(address)
if address == 0 then
return nil
end
if type(address) == 'string' then
address = tonumber(address, 16)
end
if address == nil then
return nil
end
local modulesTable = enumModules()
local size = 0
for i, v in pairs(modulesTable) do
size = getModuleSize(v.Name)
if size ~= nil then
if address >= v.Address and address <= v.Address + size then
return v.Name
end
end
end
return nil
end
local function getModuleAndOffsetFromAddress(address)
local pointerSize, pointerSizeStr, pointerFtmStr, pointerWordSize, pointerDefaultStr = getPointerSizeStrs()
if address == 0 then
return format(pointerFtmStr, address)
end
if type(address) == 'string' then
address = tonumber(address, 16)
end
if address == nil then
return address
end
local addModule = getModuleFromAddress()
if addModule then
return format('%s+%X', addModule, (address - v.Address))
end
return getNameFromAddress(address)
end
local function copyAddress()
writeToClipboard(getModuleAndOffsetFromAddress(math.min(dv_address1, dv_address2)))
end
local function copyMemoryRecordAddress()
if AddressList.SelectedRecord ~= nil then
local address = AddressList.SelectedRecord.Address
if AddressList.SelectedRecord.OffsetCount > 0 then
for i = 1, AddressList.SelectedRecord.OffsetCount do
address = readPointer(address + AddressList.SelectedRecord.Offset[i])
end
end
if address ~= nil then
writeToClipboard(getModuleAndOffsetFromAddress(address))
end
end
end
local function OnSelectionTracker(disassemblerviewLine, address, address2)
dv_address1 = address
dv_address2 = address2
end
local function addContextMenuItems()
local frmMemoryView = getMemoryViewForm()
local dv = frmMemoryView.DisassemblerView
disassemblerview_onSelectionChange(dv, OnSelectionTracker)
dv_address1 = dv.SelectedAddress
dv_address2 = dv.SelectedAddress2
popupmenu = dv.PopupMenu
mi = createMenuItem(popupmenu)
mi.Caption = t('Copy Address')
mi.onClick = copyAddress
mi.Shortcut = 'Shift+Ctrl+C'
popupmenu.Items.insert(3, mi)
popupmenu = MainForm.PopupMenu2
mi = createMenuItem(popupmenu)
mi.Caption = t('Copy Address')
mi.onClick = copyMemoryRecordAddress
mi.Shortcut = 'Shift+Ctrl+C'
popupmenu.Items.insert(2, mi)
end
addContextMenuItems()
