Package: cloudpathlib
Our goal is to be the meringue of file management libraries: the subtle sweetness ofpathlibworking in harmony with the ethereal lightness of the cloud.A Python library with classes that mimicpathlib.Path's interface for URIs from different cloud storage services.withCloudPath("s3://bucket/filename.txt").open("w+")asf:f.write("Send my changes to the cloud!")Why use cloudpathlib?Familiar: If you know how to interact withPath, you know how to interact withCloudPath. All of the cloud-relevantPathmethods are implemented.Supported clouds: AWS S3, Google Cloud Storage, and Azure Blob Storage are implemented. FTP is on the way.Extensible: The base classes do most of the work generically, so implementing two small classesMyPathandMyClientis all you need to add support for a new cloud storage service.Read/write support: Reading just works. Using thewrite_text,write_bytesor.open('w')methods will all upload your changes to cloud storage without any additional file management as a developer.Seamless caching: Files are downloaded locally only when necessary. You can also easily pass a persistent cache folder so that across processes and sessions you only re-download what is necessary.Tested: Comprehensive test suite and code coverage.Testability: Local filesystem implementations that can be used to easily mock cloud storage in your unit tests.Installationcloudpathlibdepends on the cloud services' SDKs (e.g.,boto3,google-cloud-storage,azure-storage-blob) to communicate with their respective storage service. If you try to use cloud paths for a cloud service for which you don't have dependencies installed,cloudpathlibwill error and let you know what you need to install.To install a cloud service's SDK dependency when installingcloudpathlib, you need to specify it using pip's"extras"specification. For example:pipinstallcloudpathlib[s3,gs,azure]With some shells, you may need to use quotes:pipinstall"cloudpathlib[s3,gs,azure]"Currently supported cloud storage services are:azure,gs,s3. You can also useallto install all available services' dependencies.If you do not specify any extras or separately install any cloud SDKs, you will only be able to develop with the base classes for rolling your own cloud path class.condacloudpathlibis also available usingcondafrom conda-forge. Note that to install the necessary cloud service SDK dependency, you should include the appropriate suffix in the package name. For example:condainstallcloudpathlib-s3-cconda-forgeIf no suffix is used, only the base classes will be usable. See theconda-forge/cloudpathlib-feedstockfor all installation options.Development versionYou can get latest development version from GitHub:pipinstallhttps://github.com/drivendataorg/cloudpathlib.git#egg=cloudpathlib[all]Note that you similarly need to specify cloud service dependencies, such asallin the above example command.Quick usageHere's an example to get the gist of using the package. By default,cloudpathlibauthenticates with the environment variables supported by each respective cloud service SDK.
