print('current program memory blocks:\n')
for block in currentProgram.memory.blocks:
print(block.name)
# many Ghidra functions need a Java-native array to pass or receive values
# JPype provides objects of JByte, JChar, etc. to meet this need
# this example demonstrates how you would create an array of bytes to get
# the first 10 bytes of memory from the .text section
# we need this import to get at the helper classes
import jpype
# get the block we need

# let's have a look at our new object
print(f"array class: {byte_array.__class__}")
# will be <java class 'byte[]'>
print(f"array length: {len(byte_array)}")
# we can now use this array wherever a Java method requires a byte[] type
# the signature of getBytes is getBytes(Address addr, byte[] b)
block.getBytes(block.start, byte_array)
# after the call, we can get the bytes out as desired
# we just put them in a list comprehension here
print(f"first 10 bytes of .text: {['%#x' % ((b+256)%256) for b in byte_array]}")
# if the data isn't being changed, a bytes-like objct may be used
data = b"Hello"

<BODY lang="EN-US">
<H1><A name="Pyhidra"></A>Pyhidra Interpreter</H1>
<P>
The Ghidra <I>Pyhidra Interpreter</I> provides a full general-purpose Python interactive shell
and allows you to interact with your current Ghidra session by exposing Ghidra's powerful Java
API through the magic of Jpype.
</P>
<H2>Environment</H2>
<BLOCKQUOTE>
<P>
The Ghidra <I>Pyhidra Interpreter</I> is configured to run in a similar context as a Ghidra
script. Therefore, you immediately have access to variables such as <TT>currentProgram</TT>,
<TT>currentSelection</TT>, <TT>currentAddress</TT>, etc without needing to import them.
These variables exist as Java objects behind the scenes, but Jpype allows you to interact with
them through a Python interface, which is similar to Java in some ways.
</P>
<P>
As in Java, classes outside of your current package/module need to be explicitly imported.
For example, consider the following code snippet:
</P>
<BR>
<PRE>
<FONT COLOR="GREEN"># Get a data type from the user</FONT>
tool = state.getTool()
dtm = currentProgram.getDataTypeManager()
from ghidra.app.util.datatype import DataTypeSelectionDialog
from ghidra.util.data.DataTypeParser import AllowedDataTypes
selectionDialog = DataTypeSelectionDialog(tool, dtm, -1, AllowedDataTypes.FIXED_LENGTH)
tool.showDialog(selectionDialog)
dataType = selectionDialog.getUserChosenDataType()
if dataType != None: print("Chosen data type: " + str(dataType))
</PRE>
<P>
<TT>currentProgram</TT> and <TT>state</TT> are defined within the Ghidra scripting class
hierarchy, so nothing has to be explicitly imported before they can be used. However, because
the <TT>DataTypeSelectionDialog</TT> class and <TT>AllowedDataType</TT> enum reside in
different packages, they must be explicitly imported. Failure to do so will result in a
Python <TT><FONT COLOR="RED">NameError</FONT></TT>.
</P>
</BLOCKQUOTE>
<H2><A name="Clear_Interpreter"></A>Clear <IMG border="0" src="images/erase16.png"></H2>
<BLOCKQUOTE>
<P>
This command clears the interpreter's display. Its effect is purely visual.
It does not affect the state of the interpreter in any way.
</P>
</BLOCKQUOTE>
<H2><A name="Interrupt_Interpreter"></A>Interrupt <IMG border="0" src="images/dialog-cancel.png"></H2>
<BLOCKQUOTE>
<P>
This command issues a keyboard interrupt to the interpreter, which can be used to interrupt
long running commands or loops.
</P>
</BLOCKQUOTE>
<H2><A name="Reset_Interpreter"></A>Reset <IMG border="0" src="images/reload3.png"></H2>
<BLOCKQUOTE>
<P>
This command resets the interpreter, which clears the display and resets all state.
</P>
</BLOCKQUOTE>
<H2>Keybindings</H2>
<BLOCKQUOTE>
<P>
The Ghidra <I>Pyhidra Interpreter</I> supports the following hard-coded keybindings:
<UL>
<LI><B>(up):</B>&nbsp;&nbsp;Move backward in command stack</LI>
<LI><B>(down):</B>&nbsp;&nbsp;Move forward in command stack</LI>
<LI><B>TAB:</B>&nbsp;&nbsp;Show code completion window</LI>
</UL>
<P>
With the code completion window open:
<UL>
<LI><B>TAB:</B>&nbsp;&nbsp;Insert currently-selected code completion (if no completion selected, select the first available)</LI>
<LI><B>ENTER:</B>&nbsp;&nbsp;Insert selected completion (if any) and close the completion window</LI>
<LI><B>(up):</B>&nbsp;&nbsp;Select previous code completion</LI>
<LI><B>(down):</B>&nbsp;&nbsp;Select next code completion</LI>
<LI><B>ESC:</B>&nbsp;&nbsp;Hide code completion window</LI>
</UL>
</P>
</BLOCKQUOTE>
<H2>Copy/Paste</H2>
<BLOCKQUOTE>
<P>
Copy and paste from within the Ghidra <I>Pyhidra Interpreter</I> should work as expected for
your given environment:
<UL>
<LI><B>Windows:</B>&nbsp;&nbsp;CTRL+C / CTRL+V</LI>
<LI><B>Linux:</B>&nbsp;&nbsp;CTRL+C / CTRL+V</LI>
<LI><B>OS X:</B>&nbsp;&nbsp;COMMAND+C / COMMAND+V</LI>
</UL>
</P>
</BLOCKQUOTE>
<H2>API Documentation</H2>
<BLOCKQUOTE>
<P>
The built-in <TT>help()</TT> Python function has been altered by the Ghidra <I>Pyhidra Interpreter</I>
to add support for displaying Ghidra's Javadoc (where available) for a given Ghidra class, method,
or variable. For example, to see Ghidra's Javadoc on the <TT>state</TT> variable, simply do:
<PRE>
>>> help(state)
#####################################################
class ghidra.app.script.GhidraState
extends java.lang.Object
Represents the current state of a Ghidra tool
#####################################################
PluginTool getTool()
Returns the current tool.
@return ghidra.framework.plugintool.PluginTool: the current tool
-----------------------------------------------------
Project getProject()
Returns the current project.
@return ghidra.framework.model.Project: the current project
-----------------------------------------------------
...
...
...
</PRE>
<P>
Calling help() with no arguments will show the Javadoc for the GhidraScript class.
</P>
</BLOCKQUOTE>
<H2>Additional Help</H2>
<BLOCKQUOTE>
<P>
For more information on the Jpype environment, such as how to interact with Java objects

# pyhidra
Pyhidra is a Python library that provides direct access to the Ghidra API within a native CPython interpreter using [jpype](https://jpype.readthedocs.io/en/latest). As well, Pyhidra contains some conveniences for setting up analysis on a given sample and running a Ghidra script locally. It also contains a Ghidra plugin to allow the use of CPython from the Ghidra user interface.
Pyhidra was initially developed for use with Dragodis and is designed to be installable without requiring Java or Ghidra. This allows other Python projects
have pyhidra as a dependency and provide optional Ghidra functionality without requiring all users to install Java and Ghidra. It is recommended to recommend that users set the `GHIDRA_INSTALL_DIR` environment variable to simplify locating Ghidra.
## Usage
### Raw Connection
To get a raw connection to Ghidra use the `start()` function.
This will setup a Jpype connection and initialize Ghidra in headless mode,
which will allow you to directly import `ghidra` and `java`.
*NOTE: No projects or programs get setup in this mode.*
```python
import pyhidra
pyhidra.start()
import ghidra
from ghidra.app.util.headless import HeadlessAnalyzer
from ghidra.program.flatapi import FlatProgramAPI
from ghidra.base.project import GhidraProject
from java.lang import String
# do things
```
### Customizing Java and Ghidra initialization
JVM configuration for the classpath and vmargs may be done through a `PyhidraLauncher`.
```python
from pyhidra.launcher import HeadlessPyhidraLauncher
launcher = HeadlessPyhidraLauncher()
launcher.add_classpaths("log4j-core-2.17.1.jar", "log4j-api-2.17.1.jar")
launcher.add_vmargs("-Dlog4j2.formatMsgNoLookups=true")
launcher.start()
```
### Registering an Entry Point
The `PyhidraLauncher` can also be configured through the use of a registered entry point on your own python project.
This is useful for installing your own Ghidra plugin which uses pyhidra and self-compiles.
First create an [entry_point](https://setuptools.pypa.io/en/latest/userguide/entry_point.html) for `pyhidra.setup`
pointing to a single argument function which accepts the launcher instance.
```python
# setup.py
from setuptools import setup
setup(
# ...,
entry_points={
'pyhidra.setup': [
'acme_plugin = acme.ghidra_plugin.install:setup',
]
}
)
```
Then we create the target function.
This function will be called every time a user starts a pyhidra launcher.
In the same fashion, another entry point `pyhidra.pre_launch` may be registered and will be called after Ghidra and all
plugins have been loaded.
```python
# acme/ghidra_plugin/install.py
from pathlib import Path
import pyhidra
def setup(launcher):
"""
Run by pyhidra launcher to install our plugin.
"""
launcher.add_classpaths("log4j-core-2.17.1.jar", "log4j-api-2.17.1.jar")
launcher.add_vmargs("-Dlog4j2.formatMsgNoLookups=true")
# Install our plugin.
source_path = Path(__file__).parent / "java" / "plugin" # path to uncompiled .java code
details = pyhidra.ExtensionDetails(
name="acme_plugin",
description="My Cool Plugin",
author="acme",
plugin_version="1.2",
)
launcher.install_plugin(source_path, details) # install plugin (if not already)
```
### Analyze a File
To have pyhidra setup a binary file for you, use the `open_program()` function.
This will setup a Ghidra project and import the given binary file as a program for you.
Again, this will also allow you to import `ghidra` and `java` to perform more advanced processing.
```python
import pyhidra
with pyhidra.open_program("binary_file.exe") as flat_api:
program = flat_api.getCurrentProgram()

By default, pyhidra will run analysis for you. If you would like to do this yourself, set `analyze` to `False`.
```python
import pyhidra
with pyhidra.open_program("binary_file.exe", analyze=False) as flat_api:
from ghidra.program.util import GhidraProgramUtilities
program = flat_api.getCurrentProgram()
if GhidraProgramUtilities.shouldAskToAnalyze(program):
flat_api.analyzeAll(program)
```
The `open_program()` function can also accept optional arguments to control the project name and location that gets created.
(Helpful for opening up a sample in an already existing project.)
```python
import pyhidra
with pyhidra.open_program("binary_file.exe", project_name="EXAM_231", project_location=r"C:\exams\231") as flat_api:
...
```
### Run a Script
Pyhidra can also be used to run an existing Ghidra Python script directly in your native python interpreter
using the `run_script()` command.
However, while you can technically run an existing Ghidra script unmodified, you may
run into issues due to differences between Jython 2 and CPython 3.
Therefore, some modification to the script may be needed.
```python
import pyhidra
pyhidra.run_script(r"C:\input.exe", r"C:\some_ghidra_script.py")
```
This can also be done on the command line using `pyhidra`.
```console
> pyhidra C:\input.exe C:\some_ghidra_script.py <CLI ARGS PASSED TO SCRIPT>
```
### Handling Package Name Conflicts
There may be some Python modules and Java packages with the same import path. When this occurs the Python module takes precedence.
While jpype has its own mechanism for handling this situation, pyhidra automatically makes the Java package accessible by allowing
it to be imported with an underscore appended to the package name.
```python
import pdb # imports Python's pdb
import pdb_ # imports Ghidra's pdb
```

<p>Normally, Ghidra is installed as an entire directory structure that allows modular inclusion or
removal of feature sets and also provides many files that can be extended or configured. However,
there are times when it would be useful to have all or some subset of Ghidra compressed into a
single jar file at the expense of configuration options. This makes Ghidra easier to run from the
single jar file at the expense of configuration options. This makes Ghidra easier to run from the
command line for headless operation or to use as a library of reverse engineering capabilities for
another Java application.</p>
<p>A single ghidra.jar file can be created using the
<i>&lt;GhidraInstallDir&gt;</i>/support/buildGhidraJar script.</p>
<h3><a name="RunPyhidra"></a>Pyhidra Mode</h3>
<p>Ghidra has integrated the the popular Pyhidra extension to enable native CPython 3 support out of
the box. To enable this support, Ghidra must be launched from a Python environment using special
launch scripts.</p>
<ol>
<li>
Navigate to <i>&lt;GhidraInstallDir&gt;</i>/support/
</li>
<li>
<p>Run <i>pyhidraRun.bat</i> (Windows) or <i>pyhidraRun</i> (Linux or macOS)</p>
<p>If the <b>pyhidra</b> Python module has not yet been installed, the script will offer to
install it for you, along with its dependencies. If you prefer to install it manually, execute:
<pre>python3 -m pip install --no-index -f <i>&lt;GhidraInstallDir&gt;</i>/Ghidra/Features/Pyhidra/pypkg/dist pyhidra</pre>
<b>NOTE: </b>You may also install and run Pyhidra from within a
<a href="https://docs.python.org/3/tutorial/venv.html">virtual environment</a> if you desire.
<p>If Ghidra failed to launch, see the <a href="#Troubleshooting">Troubleshooting</a> section.
</p>
</li>
</ol>
<p>Once Pyhidra has been installed, you are free to use it like any other Python module. You may
import it from other Python scripts, or launch Pyhidra using the <i>pyhidra</i> or <i>pyhidraw</i>
commands. For more information on using Pyhidra, see the
