libQasm Python Package

Project description

libQASM: Library to parse cQASM v3.0 files

CI PyPI

File organization

For development, see:

  • include: public headers.
  • src: source files.
  • test: test files.
  • python: SWIG interface.
  • res: resource files, for testing.

For build process, continuous integration, and documentation:

  • conan: Conan profiles.
  • emscripten: bindings and test for the emscripten binaries.
  • scripts: helper scripts used during the build process.
  • .github: GitHub Actions configuration files.
  • doc: documentation.

Build outputs may go into:

  • build/<build type>: the C++ library output files generated by Conan.
  • pybuild: the Python library output files generated by setup.py.

Dependencies

  • C++ compiler with C++20 support (gcc 11, clang 14, msvc 17)
  • CMake >= 3.12
  • git
  • Python 3.x plus pip, with the following package:
    • conan >= 2.0

ARM specific dependencies

We are having problems when using the zulu-opendjk Conan package on an ARMv8 architecture. zulu-openjdk provides the Java JRE required by the ANTLR generator. So, for the time being, we are installing Java manually for this platform.

  • Java JRE >= 11

Build

This version of libqasm can only be compiled via the Conan package manager. You'll need to create a default profile before using it for the first time.

The installation of dependencies, as well as the compilation, can be done in one go.

git clone https://github.com/QuTech-Delft/libqasm.git
cd libqasm
conan profile detect
conan build . -pr:a=conan/profiles/tests-debug -b missing

Notice:

  • the conan profile command only has to be run only once, and not before every build.
  • the conan build command is building libqasm in Debug mode with tests using the tests-debug profile.
  • the -b missing parameter asks conan to build packages from sources in case it cannot find the binary packages for the current configuration (platform, OS, compiler, build type...).

Build profiles

A group of predefined profiles is provided under the conan/profiles folder. They follow the [tests-](debug|release)[-compat] naming convention. For example:

  • release is a Release build without tests and compatibility with the original API.
  • tests-debug-compat is a Debug build with tests and compatibility enabled.

All the profiles set the C++ standard to 20. All the tests profiles enable Address Sanitizer.

Build options

Profiles are a shorthand for command line options. The command above could be written as well as:

conan build . -s:h compiler.cppstd=20 -s:h libqasm/*:build_type=Debug -o libqasm/*:build_tests=True -o libqasm/*:asan_enabled=True -b missing

These are the list of options that could be specified whether in a profile or in the command line:

  • libqasm/*:asan_enabled={True,False}: enables Address Sanitizer.
  • libqasm/*:build_tests={True,False}: builds tests or not.
  • libqasm/*:build_type={Debug,Release}: builds in debug or release mode.
  • libqasm/*:shared={True,False}: builds a shared object library instead of a static library, if applicable.

Install

From Python

Install from the project root directory as follows:

python3 -m pip install --verbose .

You can test if it works by running:

python3 -m pytest

From C++

The CMakeLists.txt file in the root directory includes install targets:

conan create --version 0.5.2 . -pr=tests-debug -b missing

You can test if it works by doing:

cd test/Debug
ctest -C Debug --output-on-failure

Use from another project

From Python

After installation, you should be able to use the bindings for the original API by just import libQasm. The new API doesn't have Python bindings yet.

From C++

The easiest way to use libqasm in a CMake project is to fetch the library and then link against it.

include(FetchContent)
FetchContent_Declare(cqasm
    GIT_REPOSITORY https://github.com/QuTech-Delft/libqasm.git
    GIT_TAG "<a given cqasm git tag>"
)
FetchContent_MakeAvailable(cqasm)
target_include_directories(<your target> SYSTEM PRIVATE "${cqasm_SOURCE_DIR}/include")
target_link_libraries(<your target> PUBLIC cqasm)

Note that the following dependency is required for libqasm to build:

  • Java JRE >= 11

The original API headers are not included by default. To enable those, pass -o libqasm/*:compat=True as a build option to Conan.

Docker

This tests the library in a container with the bare minimum requirements for libqasm.

docker build .

Note for Windows users: The above might fail on Windows to the autocrlf transformation that git does. If you are having trouble with this just create new clone of this repository using:

git clone --config core.autocrlf=input git@github.com:QuTech-Delft/libqasm.git

Emscripten

The generation of emscripten binaries has been tested as a cross-compilation from an ubuntu/x64 platform.

conan build . -pr=conan/profiles/emscripten -pr:b=conan/profiles/release -b missing

The output of this build lives in build/Release/emscripten:

  • cqasm_emscripten.js.
  • cqasm_emscripten.wasm.
