* Set of extra helpers (stack visualization, blockchain context mocking)
#### Michelson Jupyter kernel
* Custom interpreter with runtime type checker
* Syntax highlighting, autocomplete with `Tab`
* In-place docstrings with `Shift+Tab`
* Macros support
* Verbose execution logging

#### Michelson integration testing framework
* Writing integration tests using `unittest` package
* Simulating contract execution using remote intepreter (via RPC) or builtin one
## Installation
Make sure you have Python 3.8 to 3.12 installed and set as default in the system.
You also need to install cryptographic packages before installing the library/building the project:
### Linux
#### Ubuntu, Debian and other apt-based distributions
```shell
$ sudo apt install libsodium-dev libgmp-dev pkg-config
```
#### Arch Linux
```shell
$ sudo pacman -Syu --needed libsodium gmp
```
### MacOS
[Homebrew](https://brew.sh/) needs to be installed.
```shell
$ brew install libsodium gmp pkg-config
```
#### M1 (ARM)
In case `libsodium` or `gmp` cannot find either include or lib paths, try explicitly set environment vars:
```shell
export CFLAGS="-I/opt/homebrew/Cellar/gmp/6.2.1_1/include/ -L/opt/homebrew/Cellar/gmp/6.2.1_1/lib/"
export DYLD_LIBRARY_PATH=/opt/homebrew/lib/
pip3 install --user pytezos
```
For running tests you might also need to export `LD_LIBRARY_PATH`:
```shell
export LD_LIBRARY_PATH=/opt/homebrew/lib/
```
### Windows
The recommended way is to use WSL and then follow the instructions for Linux,
but if you feel lucky you can try to install natively:
1. Install MinGW from [https://osdn.net/projects/mingw/](https://osdn.net/projects/mingw/)
2. Make sure `C:\MinGW\bin` is added to your `PATH`
3. Download the latest libsodium-X.Y.Z-msvc.zip from [https://download.libsodium.org/libsodium/releases/](https://download.libsodium.org/libsodium/releases/).
4. Extract the Win64/Release/v143/dynamic/libsodium.dll from the zip file
5. Copy libsodium.dll to C:\Windows\System32\libsodium.dll
### From PyPi
```shell
$ pip install wheel setuptools pkginfo cryptography
$ pip install pytezos
```
### [Google Colab](https://colab.research.google.com)
`````python
>>> !apt install libsodium-dev libgmp-dev
>>> !pip install pytezos
`````
### Docker container
Verified & minified images for CI/CD https://hub.docker.com/r/bakingbad/pytezos/tags
```shell
$ # 1. Use image from registry
$ docker pull bakingbad/pytezos
$ # or build it yourself
$ docker build . -t pytezos
$ # 2. Use included docker-compose.yml
$ docker-compose up -d notebook
```
### Building from sources
Requirements:
* Python 3.8 to 3.12
* libsodium, coincurve, gmp
* make
```shell
$ # prepare environment
$ make install
# # run full CI with tests
$ make all
```
## Quick start
Read [quick start guide](https://pytezos.org/quick_start.html)
Learn how to [enable Jupyter with Michelson](./src/michelson_kernel/README.md)
## API reference

### Inline documentation
If you are working in Jupyter/Google Colab or any other interactive console, you can display documentation for a particular class/method:
```python
>>> from pytezos import pytezos
>>> pytezos
```
