CycloneDX Conan SBOM Generation Tool

Support for Conan v2 and later

CycloneDX support for Conan2 is available as an offical Conan2 extension.
See the conan-extensions sbom commands.

This project provides a tool for generating CycloneDX bill-of-material JSON documents for C/C++ projects using Conan v1.

The BOM will contain an aggregate of all your current project's dependencies, including a full dependency graph.

CycloneDX is a lightweight BOM specification that is easily created, human-readable, and simple to parse.

Please note: This tool has only been tested with Conan v1.14 so far.

Installation

Install this from PyPi.org using your preferred Python package manager.

Example using pip:

pip install cyclonedx-conan

Example using poetry:

poetry add cyclonedx-conan

Usage

Once installed, you can access the full documentation by running --help:

The command line options are aligned to the standard Conan options.

$ cyclonedx-conan --help

                       path_or_reference

CycloneDX SBOM Generator

positional arguments:
  path_or_reference     Path to a folder containing a recipe (conanfile.py or conanfile.txt) or to a recipe file.
                        e.g., ./my_project/conanfile.txt. It could also be a reference

options:
  -h, --help            show this help message and exit
  -if INSTALL_FOLDER, --install-folder INSTALL_FOLDER
                        local folder containing the conaninfo.txt and conanbuildinfo.txt files (from a previous conan install execution).
                        Defaulted to current folder, unless --profile, -s or -o is specified.
                        If you specify both install-folder and any setting/option it will raise an error.
  -db [DRY_BUILD], --dry-build [DRY_BUILD]
                        Apply the --build argument to output the information, as it would be done by the install command
  --output FILE_PATH
                        Output file path for your SBOM (set to '-' to output to STDOUT)
  --exclude-dev         Exclude development dependencies from the BOM
  -b [BUILD], --build [BUILD]
                        Given a build policy, return an ordered list of packages that would be built from sources during the install command
  -r REMOTE, --remote REMOTE
                        Look in the specified remote server
  -u, --update          Will check if updates of the dependencies exist in the remotes 
                        (a new version that satisfies a version range, a new revision or a newer recipe if not using revisions).
  -l LOCKFILE, --lockfile LOCKFILE
                        Path to a lockfile
  --lockfile-out LOCKFILE_OUT
                        Filename of the updated lockfile
  -e ENV_HOST, --env ENV_HOST
                        Environment variables that will be set during the package build (host machine).

  -e:b ENV_BUILD, --env:build ENV_BUILD
                        Environment variables that will be set during the package build (build machine).

Python Support

We endeavour to support all functionality for all current actively supported Python versions. However, some features may not be possible/present in older Python versions due to their lack of support.

Contributing

Pull requests are welcome. But please read the CycloneDX contributing guidelines first.

It is generally expected that pull requests will include relevant tests. Tests are automatically run on Windows, MacOS and Linux for every pull request.

Thanks to Gitpod there are two really easy ways of creating a ready to go development environment with VS Code.

You can open a Gitpod hosted development environment in your browser. Or you can start a local instance of the OpenVSCode Server by running the localdev.sh script (requires Docker).
