## install

### install via pip
> Note: To use GPGPU algorithms, please follow the section [`install via pip from source codes`](#install-via-pip-from-source-codes) below.
> GPGPU algorithms are automatically enabled once CMake finds CUDA frameworks during installation.
```
# Binary
$ pip install openjij 
# From Source (CUDA)
$ pip install --no-binary=openjij,jij-cimod  openjij
```

### install via pip from source codes
To install OpenJij from source codes, please install CMake first then install OpenJij.

#### cmake setup
If you want to use setup.py instead of PIP, You will need to install CMake\>\=3.22.  
We are Highly recommended install CMake via PYPI.
```
$ pip install -U cmake
```

Make sure the enviroment path for CMake is set correctly.

#### install OpenJij

```
$ pip install --no-binary=openjij,jij-cimod openjij
```

### install from github repository
```
$ git clone git@github.com:OpenJij/OpenJij.git
$ cd openjij
$ python -m pip install -vvv .
```
## For Contributor 
Use `pre-commit` for auto chech before git commit.
`.pre-commit-config.yaml`
``` 
# pipx install pre-commit 
# or 
# pip install pre-commit
pre-commit install
```

## Test 

### Python 
```sh
$ python -m venv .venv
$ pip install pip-tools 
$ pip-compile
$ pip-compile dev-requirements.in
$ pip-sync requirements.txt dev-requirements.txt
$ source .venv/bin/activate
$ export CMAKE_BUILD_TYPE=Debug
$ python setup.py --force-cmake install --build-type Debug -G Ninja
$ python setup.py --build-type Debug test 
$ python -m coverage html
```

### C++ 
```sh
$ mkdir build 
$ cmake -DCMAKE_BUILD_TYPE=Debug -S . -B build
$ cmake --build build --parallel
$ cd build
$ ./tests/cxxjij_test
# Alternatively  Use CTest 
$ ctest --extra-verbose --parallel --schedule-random
```

Needs: CMake > 3.22, C++17

- Format 
``` sh
$ python -m isort 
$ python -m black 
```

- Aggressive Format
```sh 
$ python -m isort --force-single-line-imports --verbose ./openjij
$ python -m autoflake --in-place --recursive --remove-all-unused-imports --ignore-init-module-imports --remove-unused-variables ./openjij
$ python -m autopep8 --in-place --aggressive --aggressive  --recursive ./openjij
$ python -m isort ./openjij
$ python -m black ./openjij
```

- Lint
``` sh 
$ python -m flake8
$ python -m mypy
$ python -m pyright
```


## How to use

### Python example

```python
import openjij as oj
sampler = oj.SASampler()
response = sampler.sample_ising(h={0: -1}, J={(0,1): -1})
response.states
# [[1,1]]

# with indices
response = sampler.sample_ising(h={'a': -1}, J={('a','b'): 1})
[{index: s for index, s in zip(response.indices, state)} for state in response.states]
# [{'b': -1, 'a': 1}]
```

### C++ example

```
$ source ./build_gcc.sh
$ cd ./project_template
$ make
$ ./tutorial
The result spins are [1 1 1 1 1 ]
```
