filemetadata module

binaryninja.filemetadata.FileMetadata([...])	class FileMetadata represents the file being analyzed by Binary Ninja.
binaryninja.filemetadata.NavigationHandler()
binaryninja.filemetadata.SaveSettings([handle])	class SaveSettings is used to specify actions and options that apply to saving a database (.bndb).

class FileMetadata(filename: str | None = None, handle: LP_BNFileMetadata | None = None)

Bases: object

class FileMetadata represents the file being analyzed by Binary Ninja. It is responsible for opening, closing, creating the database (.bndb) files, and is used to keep track of undoable actions.

Parameters:

• filename (str | None) –

• handle (LP_BNFileMetadata | None) –

begin_undo_actions(anonymous_allowed: bool = True) → str

begin_undo_actions starts recording actions taken so they can be undone at some point.

Parameters:

anonymous_allowed (bool) – Legacy interop: prevent empty calls to commit_undo_actions` from affecting this undo state. Specifically for undoable_transaction`

Returns:

Id of undo state, for passing to commit_undo_actions` or revert_undo_actions.

Return type:

str

Example:

>>> bv.get_disassembly(0x100012f1)
'xor     eax, eax'
>>> state = bv.begin_undo_actions()
>>> bv.convert_to_nop(0x100012f1)
True
>>> bv.commit_undo_actions(state)
>>> bv.get_disassembly(0x100012f1)
'nop'
>>> bv.undo()
>>> bv.get_disassembly(0x100012f1)
'xor     eax, eax'
>>>

close() → None

Closes the underlying file handle. It is recommended that this is done in a finally clause to avoid handle leaks.

Return type:

None

close_project() → None

Return type:

None

commit_undo_actions(id: str | None = None) → None

commit_undo_actions commits the actions taken since a call to begin_undo_actions Pass as id the value returned by begin_undo_actions. Empty values of id will commit all changes since the last call to begin_undo_actions.

Parameters:

id (Optional[str]) – id of undo state, from begin_undo_actions

Return type:

None

Example:

>>> bv.get_disassembly(0x100012f1)
'xor     eax, eax'
>>> state = bv.begin_undo_actions()
>>> bv.convert_to_nop(0x100012f1)
True
>>> bv.commit_undo_actions(state)
>>> bv.get_disassembly(0x100012f1)
'nop'
>>> bv.undo()
>>> bv.get_disassembly(0x100012f1)
'xor     eax, eax'
>>>

create_database(filename: str, progress_func: Callable[[int, int], bool] | None = None, settings: SaveSettings | None = None) → bool

create_database writes the current database (.bndb) out to the specified file.

Parameters:

• filename (str) – path and filename to write the bndb to, this string should have “.bndb” appended to it.

• progress_func (callback) – optional function to be called with the current progress and total count.

• settings (SaveSettings) – optional argument for special save options.

Returns:

true on success, false on failure

Return type:

bool

Note

The progress_func callback must return True to continue the save operation, False will abort the save operation.

Warning

The calling thread must not hold a lock on the BinaryView instance as this action is run on the main thread which requires the lock.

Example:

>>> settings = SaveSettings()
>>> bv.file.create_database(f"{bv.file.filename}.bndb", None, settings)
True

Parameters:

• filename (str) –

• progress_func (Callable[[int, int], bool] | None) –

• settings (SaveSettings | None) –

Return type:

bool

Parameters:

name (str) –

Return type:

BinaryView | None

is_project_open() → bool

Return type:

bool

navigate(view: str, offset: int) → bool

navigate navigates the UI to the specified virtual address

Note

Despite the confusing name, view in this context is not a BinaryView but rather a string describing the different UI Views. Check view while in different views to see examples such as Linear:ELF, Graph:PE.

Parameters:

• view (str) – view name

• offset (int) – address to navigate to

Returns:

whether or not navigation succeeded

Return type:

bool

Example:

>>> import random

True

redo() → None

redo redo the last committed transaction in the undo database.

Return type:

None

undoable_transaction() → Generator

undoable_transaction gives you a context in which you can make changes to analysis, and creates an Undo state containing those actions. If an exception is thrown, any changes made to the analysis inside the transaction are reverted.

Returns:

Transaction context manager, which will commit/revert actions depending on if an exception is thrown when it goes out of scope.

Return type:

Generator

Example:

>>> bv.get_disassembly(0x100012f1)
'xor     eax, eax'
>>> # Actions inside the transaction will be committed to the undo state upon exit

'nop'
>>> bv.undo()
>>> bv.get_disassembly(0x100012f1)
'xor     eax, eax'
>>> # A thrown exception inside the transaction will undo all changes made inside it
