# Examples

## IDAPython examples

This collection of examples organizes all IDAPython sample code into [categories](#example-categories-overview) for easy reference. Each example demonstrates practical implementation for the IDAPython API, complementing the [reference documentation](https://python.docs.hex-rays.com/) with a real-world usage scenario.

### How to run the examples?

#### Load the script via File Loader

1. Navigate to **File -> Script file...**.
2. In the new dialog, select the `.py` script you want to run and click **Open**.

#### Load the script via Script command

1. Navigate to **File -> Script command...**.
2. Paste the code into _Please enter script body_ field and click **Run**.

#### Load the script via output window/console

1. In the output window/IDAPython console, type the following command: `exec(open("path/to/your_script.py").read())` to execute the script.

## Examples list


### Assign a shortcut to a custom function {#add_hotkey}
`ida_kernwin.add_hotkey` is a simpler, but much less flexible
alternative to `ida_kernwin.register_action` (though it does
use the same mechanism under the hood.)

It's particularly useful during prototyping, but note that the
actions that are created cannot be inserted in menus, toolbars
or cannot provide a custom `ida_kernwin.action_handler_t.update`
callback.

**APIs Used:**
* `ida_kernwin.add_hotkey`
* `ida_kernwin.del_hotkey`

***


### Add custom menus to IDA {#add_menus}
It is possible to add custom menus to IDA, either at the
toplevel (i.e., into the menubar), or as submenus of existing
menus.

Notes:

  * the same action can be present in more than 1 menu
  * this example does not deal with context menus

### Assign a background color to an address, function & segment {#colorize_disassembly}
This illustrates the setting/retrieval of background colours
using the IDC wrappers

In order to do so, we'll be assigning colors to specific ranges
(item, function, or segment). Those will be persisted in the
database.

### Create a dockable container, and populate it with Qt widgets {#populate_pluginform_with_pyqt_widgets}
Using `ida_kernwin.PluginForm.FormToPyQtWidget`, this script
converts IDA's own dockable widget into a type that is
recognized by PyQt5, which then enables populating it with
regular Qt widgets.

inserted in menus, toolbars, context menus, ...

Those actions, when triggered, will be passed a 'context'
that contains some of the most frequently needed bits of
information.

In addition, custom actions can determine when they want
to be available (through their
`ida_kernwin.action_handler_t.update` callback)

### Implement a "jump to next comment" action within IDA's listing {#jump_next_comment}
We want our action not only to find the next line containing a comment,
but to also place the cursor at the right horizontal position.

To find that position, we will have to inspect the text that IDA
generates, looking for the start of a comment.
However, we won't be looking for a comment "prefix" (e.g., "; "),
as that would be too fragile.

Instead, we will look for special "tags" that IDA injects into textual
lines, and that bear semantic information.

Those tags are primarily used for rendering (i.e., switching colors),
but can also be very handy for spotting tokens of interest (registers,
addresses, comments, prefixes, instruction mnemonics, ...)

### Dynamically colorize [parts of] lines {#lines_rendering}
Shows how one can dynamically alter the lines background
rendering (as opposed to, say, using ida_nalt.set_item_color()),
and also shows how that rendering can be limited to just a few
glyphs, not the whole line.

### Save, and then restore, positions in a listing {#save_and_restore_listing_pos}
Shows how it is possible re-implement IDA's bookmark capability,
using 2 custom actions: one action saves the current location,
and the other restores it.

Note that, contrary to actual bookmarks, this example:

  * remembers only 1 saved position
  * doesn't save that position in the IDB (and therefore cannot
    be restored if IDA is closed & reopened.)

### Retrieve the selection from the "Strings" window {#show_selected_strings}
In IDA it's possible to write actions that can be applied even to
core (i.e., "standard") widgets. The actions in this example use the
action "context" to know what the current selection is.

This example shows how you can either retrieve string literals data
directly from the chooser (`ida_kernwin.get_chooser_data`), or
by querying the IDB (`ida_bytes.get_strlit_contents`)

### Follow the movements of one graph, in another {#sync_two_graphs}
Since it is possible to be notified of movements that happen
take place in a widget, it's possible to "replay" those
movements in another.

In this case, "IDA View-B" (will be opened if necessary) will
show the same contents as "IDA View-A", slightly zoomed out.

It's possible to invoke any action programmatically, by using
either of those two:

  * ida_kernwin.execute_ui_requests()
  * ida_kernwin.process_ui_action()

Ideally, this script should be run through the "File > Script file..."
menu, so as to keep focus on "IDA View-A" and have the
'ProcessUiActions' part work as intended.

### Restore custom widgets across sessions {#auto_instantiate_widget_plugin}
This is an example demonstrating how one can create widgets from a plugin,
and have them re-created automatically at IDA startup-time or at desktop load-time.

This example should be placed in the 'plugins' directory of the
IDA installation, for it to work.

There are 2 ways to use this example:
1) reloading an IDB, where the widget was opened
   - open the widget ('View > Open subview > ...')
   - save this IDB, and close IDA
   - restart IDA with this IDB
     => the widget will be visible

2) reloading a desktop, where the widget was opened
   - open the widget ('View > Open subview > ...')
   - save the desktop ('Windows > Save desktop...') under, say, the name 'with_auto'
   - start another IDA instance with some IDB, and load that desktop
     => the widget will be visible

### Colorize lines interactively {#colorize_disassembly_on_the_fly}
This builds upon the `ida_kernwin.UI_Hooks.get_lines_rendering_info`
feature, to provide a quick & easy way to colorize disassembly
lines.

Contrary to @colorize_disassembly, the coloring is not persisted in
the database, and will therefore be lost after the session.

By triggering the action multiple times, the user can "carousel"
across 4 predefined colors (and return to the "no color" state.)

widget ("IDA View-A", "Hex View-1", "Pseudocode-A", ...) as
two "cursors", and from there retrieve (in fact, generate)
the corresponding text.

After running this script:

  * select some text in one of the listing widgets (i.e.,
    "IDA View-...", "Local Types", "Pseudocode-...")
  * press Ctrl+Shift+S to dump the selection

### Inject commands in the "Output" window {#inject_command}
This example illustrates how one can execute commands in the
"Output" window, from their own widgets.

A few notes:

* the original, underlying `cli:Execute` action, that has to be
  triggered for the code present in the input field to execute
  and be placed in the history, requires that the input field
  has focus (otherwise it simply won't do anything.)
* this, in turn, forces us to do "delayed" execution of that action,
  hence the need for a `QTimer`
* the IDA/SWiG 'TWidget' type that we retrieve through
  `ida_kernwin.find_widget`, is not the same type as a
  `QtWidgets.QWidget`. We therefore need to convert it using
  `ida_kernwin.PluginForm.TWidgetToPyQtWidget`

### Paint text on graph view edges {#paint_over_graph}
This sample registers an action enabling painting of a recognizable
string of text over horizontal nodes edge sections beyond a
satisfying size threshold.

In a disassembly view, open the context menu and select
"Paint on edges". This should work for both graph disassembly,
and proximity browser.

Using an "event filter", we will intercept paint events
targeted at the disassembly view, let it paint itself, and
then add our own markers along.

### Showcase (some of) the iterators available on a function {#list_function_items}
This demonstrates how to use some of the iterators available on the func_t type.

This example will focus on:

  * `func_t[.__iter__]`: the default iterator; iterates on instructions
  * `func_t.data_items`: iterate on data items contained within a function
  * `func_t.head_items`: iterate on 'heads' (i.e., addresses containing
                         the start of an instruction, or a data item.
  * `func_t.addresses`: iterate on all addresses within function (code
                        and data, beginning of an item or not)

Type `help(ida_funcs.func_t)` for a full list of iterators.

In addition, one can use:

  * `func_tail_iterator_t`: iterate on all the chunks (including
                            the main one) of the function
  * `func_parent_iterator_t`: iterate on all the parent functions,
                              that include this chunk

### Record and replay changes in function prototypes {#replay_prototypes_changes}
This is a sample script, that will record (in memory) all changes in
functions prototypes, in order to re-apply them later.

To use this script:
 - open an IDB (say, "test.idb")
 - modify some functions prototypes (e.g., by triggering the 'Y'
   shortcut when the cursor is placed on the first address of a
   function)
 - reload that IDB, *without saving it first*
 - call rpc.replay(), to re-apply the modifications.

Note: 'ti_changed' is also called for changes to the function
frames, but we'll only record function prototypes changes.

### Add a new member to an existing function frame {#add_frame_member}
The goal of this script is to demonstrate some usage of the type API.
In this script, we show a way to add a new frame member (a pointer to
 an uint64) inside a wide enough gap in the frame:
* Get the function object surrounding cursor location.
* Use this function to retrieve the corresponding frame object.
* Find a wide enough gap to create our new member.
* If found, we use cal_frame_offset() to get the actual
  offset in the frame structure.
* Use the previous result to add the new member.

IDA can be extended to support certain data types that it
does not know about out-of-the-box.

A 'custom data type' provide information about the type &
size of a piece of data, while a 'custom data format' is in
charge of formatting that data (there can be more than
one format for a specific 'custom data type'.)

### List operands representing a "path" to a (possibly nested) structure member {#list_struct_accesses}
It is possible to assign, to instruction operands, the notion of "structure
offset", which really is a pointer to a specific offset in a type, leading
to a possible N-deep path within types.

E.g., assuming the following types

        struct c
        {
            int foo;
            int bar;
            int baz;
            int quux;
            int trail;
        };

        struct b
        {
            int gap;
            c c_instance;
        };

        struct a
        {
            int count;
            b b_instance;
        };

and assuming an instruction that initially looks like this:

        mov eax, 10h

by pressing `t`, the user will be able set the "structure offset"
to either:

  * `c.trail`
  * `b.c_instance.quux`
  * `a.b_inscance.c_instance.baz`

Here's why IDA offers `a.b_inscance.c_instance.baz`:

        0000   struct a
               {
        0000       int count;
        0004       struct b
                   {
        0004           int gap;
        0008           struct c
                       {
        0008               int foo;
        000C               int bar;
        0010               int baz;
        0014               int quux;
        0018               int trail;
                       };
                   };
               };

This sample shows how to programmatically retrieve information about
that "structure member path" that an operand was made pointing to.

### Produce C listing for the entire file {#produce_c_file}
Automate IDA to perform auto-analysis on a file and,
once that is done, produce a .c file containing the
decompilation of all the functions in that file.

Run like so:

      ida -A "-S...path/to/produce_c_file.py" <binary-file>

where:

  * -A instructs IDA to run in non-interactive mode
  * -S holds a path to the script to run (note this is a single token;
       there is no space between '-S' and its path.)

### Dynamically provide a custom call type {#vds21}
This plugin can greatly improve decompilation of indirect calls:

    call    [eax+4]

For them, the decompiler has to guess the prototype of the called function.
This has to be done at a very early phase of decompilation because
the function prototype influences the data flow analysis. On the other
hand, we do not have global data flow analysis results yet because
we haven't analyzed all calls in the function. It is a chicked-and-egg
problem.

The decompiler uses various techniques to guess the called function
prototype. While it works very well, it may fail in some cases.

To fix, the user can specify the call prototype manually, using
"Edit, Operand types, Set operand type" at the call instruction.

This plugin illustrates another approach to the problem:
if you happen to be able to calculate the call prototypes dynamically,
this is how to inform the decompiler about them.

### Dump C-tree graph {#vds5}
Registers an action that can be used to show the graph of the ctree.
The current item will be highlighted in the graph.

The command shortcut is `Ctrl+Shift+G`, and is also added
to the context menu.

To display the graph, we produce a .gdl file, and
request that ida displays that using `ida_gdl.display_gdl`.

### Create a structure with bitfield members {#create_bfstruct}
The goal of this script is to demonstrate some usage of the type API.
In this script, we:
 * Create a bitfield structure. In the present case the bitfield is an int32
made of three 'members' spanning it entirely:
    bit0->bit19: bf1
    bit20->bit25: bf2
    bit26->bit31: bf3
 * For each member create a repeatable comment.

### Get information about the "innermost" member of a structure {#get_innermost_member}
Assuming the 2 following types:

        struct b
        {
            int low;
            int high;
        };

        struct a
        {
            int foo;
            b b_instance;
            int bar;
        };

looking at an offset of 5 bytes inside an `a` instance, might be
interpreted as pointing somewhere inside member `b_instance`, of type `b`.
Alternatively, that same offset might be intprereted as pointing
somewhere inside `low`, of type `int`.

We refer to that latter interpretation as "innermost", and this sample
shows how the API lets us "drill down" to retrieve that innermost member.

### Change the type & name of a function stack frame variable {#change_stkvar_type}
The goal of this script is to demonstrate some usage of the type API.

In this script, we show a way to change the type and the name
of a stack variable. In this case we will take advantage of the
fact that RtlImageNtHeader calls RtlImageNtHeaderEx which takes
a pointer to PIMAGE_NT_HEADERS as its fourth parameter and, for
this, uses a stack variable of its caller.

* Get the function object for RtlImageNtHeader.
* Iterate through the function item to localize the load of the
  stack variable address before the call to RtlImageNtHeaderEx. We
   keep this information.
* Localize the call and take advantage of the previoulsy stored
  instruction to get the stack variable index in the frame.
* Set the type and rename the stack variable.

### Implement merging functionality for custom plugins {#py_mex3}
IDA Teams uses a chooser to display the merge conflicts.
To fill the chooser columns IDA Teams uses the following methods from diff_source_t type:

  * print_diffpos_name()
  * print_diffpos_details()

and UI hints from merge_handler_params_t type:

  * ui_has_details()
  * ui_complex_details()
  * ui_complex_name()

In general, chooser columns are filled as following:

          columns.clear()
          NAME = print_diffpos_name()
          if ui_complex_name()
          then
            columns.add(split NAME by ui_split_char())
          else
            columns[0] = NAME
          if not ui_complex_details()
          then
            columns.add(print_diffpos_details())

Also, see SDK/plugins/mex3 example
