DQCsim, short for Delft Quantum & Classical simulator, is a *framework* that
can be used to tie *components* of quantum computer simulators together in a
*standardized* yet *flexible*, *developer-friendly*, and *reproducible* way.
Click [here](https://qe-lab.github.io/dqcsim/) for more information!

## Install

The recommended method to install DQCsim is through Python's package manager:

```bash
sudo pip3 install dqcsim

## Build and test from source

**Setup**

The core of DQCsim is written in Rust. The crate defines a set of C-bindings to
support plugin development in other languages. DQCsim is distributed as a
*batteries included* Python package that includes the shared library and
headers for C and C++ plugin development.

**Requirements**

- [Rust](https://rustup.rs/) (stable)

Python support:

- [Python](https://www.python.org/downloads/) (3.5+)
- [Swig](https://github.com/swig/swig/)

C/C++ tests:

- [CMake](https://github.com/Kitware/CMake) (3.14+)

Documentation:

- [mdbook](https://github.com/rust-lang/mdBook)
- [pdoc](https://pypi.org/project/pdoc/)
- [Doxygen](https://github.com/doxygen/doxygen)

### Python

To build the `dqcsim` Python package:

```bash
python3 setup.py bdist_wheel
```

This builds a release wheel to `target/python/dist/`. For debug builds set the
`DQCSIM_DEBUG` environment variable.

### C/C++

To build the C and C++ headers build the `dqcsim` Rust crate with the
`bindings` feature enabled:

```bash
cargo build --manifest-path=rust/Cargo.toml --features=bindings
```

The generated headers are stored in `target/include`.

### Rust

The `dqcsim` crate can be built with the following (non-default) features:

- `cli`:  the command-line interface binary
- `null-plugins`: the null (no-op) plugin binaries
- `bindings`: genertion of headers required for C, C++ and Python plugin
  development

To build all targets and features:

```bash
cargo build --all-targets --all-features
```

Add `--release` for release builds.

### Documentation

To build the documentation use the [Makefile](./doc/Makefile) in the
[doc](./doc) directory directly from the root of the repository:

```bash
make -C doc
```

Documentation output is stored in `target/book`.

### Test

#### Rust

To test all targets and features:

```bash
cargo test --all-targets --all-features
```

#### C/C++

To test the C-bindings and C++ wrapper:

```bash
mkdir build
cd build
cmake .. -DBUILD_TESTS=ON
make
CTEST_OUTPUT_ON_FAILURE=1 make test
```

Add `-DCMAKE_BUILD_TYPE=DEBUG` to CMake for debug builds.

#### Python

To test the Python package:

```bash
python3 setup.py build test
```
