# Cyberbrain: Python debugging, **redefined**.

Cyberbrain[1](#footnote1)(电子脑) aims to free programmers from debugging. It lets you:
- **Backtrace variable changes**.
- See **every state** of program execution, including **variables' values**
- **Debug loops** with confidence.
Never spend hours stepping through a program, let Cyberbrain tell you what happened.
[Read more](docs/Features.md) about existing features, and [roadmaps](#roadmaps) for features to come.
I gave a talk at PyCascades 2021 about Cyberbrain, **[watch it here](https://www.youtube.com/watch?v=eXlTVrNZ67Q)**.
## Install
Cyberbrain consists of a Python library and various editor/IDE integrations. Currently it supports **[VS Code](https://code.visualstudio.com/)** and **[Gitpod](https://www.gitpod.io/)**. See our [plan](https://github.com/laike9m/Cyberbrain/issues/24) on expanding the support.
To install Cyberbrain:
```
pip install cyberbrain
code --install-extension laike9m.cyberbrain
```
You can also install from [PyPI](https://pypi.org/project/cyberbrain/) , [VS Code marketplace](https://marketplace.visualstudio.com/items?itemName=laike9m.cyberbrain) or [Open VSX](https://open-vsx.org/extension/laike9m/cyberbrain) .
**Or, you can try Cyberbrain online:** [](https://gitpod.io/#snapshot/f19f41cd-08ce-40be-a668-f7d61b7083da)
## How to Use
Suppose you want to trace a function `foo`, just decorate it with `@trace`:
```python
from cyberbrain import trace
# As of now, you can only have one @trace decorator in the whole program.
# We may change this in version 2.0, see https://github.com/laike9m/Cyberbrain/discussions/73
@trace # Disable tracing with `@trace(disabled=True)`
def foo():
...
```
Cyberbrain keeps your workflow unchanged. You run a program (from vscode or command line, both work), and a new panel will be opened to visualize how your program executed.
The following gif demonstrates the workflow (click to view the full size image):
Read our **[documentation](docs/Features.md)** to learn more about Cyberbrain's features and limitations.
❗Note on use❗
- Cyberbrain may conflict with other debuggers. If you set breakpoints and use VSC's debugger, Cyberbrain may not function normally. Generally speaking, **prefer "Run Without Debugging"** (like shown in the gif).
- If you have multiple VS Code window opened, the trace graph will always be created in the first one. [#72](https://github.com/laike9m/Cyberbrain/discussions/72) is tracking this issue.
- When having multiple decorators, you should put `@trace` as the innermost one.
```python
@app.route("/")
@trace
def hello_world():
x = [1, 2, 3]
return "Hello, World!"
```
## Roadmaps
*Updated 2020.11*
Cyberbrain is new and under active development, bugs are expected. If you met any, please [create an issue](https://github.com/laike9m/Cyberbrain/issues/new). At this point, you should **NOT** use Cyberbrain in production. We'll release 1.0 when it's ready for production.
Major features planned for future versions are listed below. It may change over time.
| Version | Features |
|:-------:|---------------------------------|
| 1.0 | Code & trace interaction ([#7][m1]), API specification |
| 2.0 | Multi-frame tracing (👉 [I need your feedback for this feature](https://github.com/laike9m/Cyberbrain/discussions/73)) |
| 3.0 | `async` support, remote debugging |
| 4.0 | Fine-grained symbol tracing |
| 5.0 | Multi-threading support |

## How does it compare to other tools?
PySnooper
PySnooper and Cyberbrain share the same goal of reducing programmers' work while debugging, with a fundamental difference: Cyberbrain traces and shows the sources of each variable change, while PySnooper only logs them. The differences should be pretty obvious after you tried both.
Debug Visualizer
Debug visualizer and Cyberbrain have different goals. Debug visualizer visualizes data structures, while Cyberbrain visualizes program execution (but also lets you inspect values).
Python Tutor
Python Tutor is for education purposes, you can't use it to debug your own programs. It's a brilliant tool for its purpose and I do it like it very much.
Static analysis
Cyberbrain is *NOT* static analyis. It's runtime tracing. Static analysis can't provide enough information for debugging.

## Support
Cyberbrain is a huge and complicated project that will last for years, but once finished, it will reshape how people think and do debugging. Your support can help sustain it. Let's make it the best Python debugging tool 🤟!
