| They've actually open sourced almost everything you need. It includes the cli, the virtual filesystem, and the backend. From github: Sapling SCM is comprised of three main components: The Sapling client: The client-side sl command line and web interface for users to interact with Sapling SCM. Mononoke: A highly scalable distributed source control server. (Not yet supported publicly.) EdenFS: A virtual filesystem for efficiently checking out large repositories. (Not yet supported publicly.) And from the mononoke page: Mononoke is still in development. We are making it available now because we plan to start making references to it from our other open source projects. The version that we provide on GitHub is omitting some functions. This is because the code is exported verbatim from an internal repository at Facebook, and not all of the scaffolding from our internal repository can be easily extracted. The key areas where we need to shore things up are: Support for running thrift based apis. Production metadata SQL support (e.g. something like a MySQL backend). We provide sqlite in OSS for now. Production blobstore storage backends (e.g. something like S3). We provide SQL (on sqlite) and File System backends currently in OSS. Linux is Mononoke's primary target plaform with OSS CI also running on MacOS. Other Unix-like OSes may be supported in the future. |
I'm not holding my breath either; EdenFS was open-sourced many years ago with broken-for-OSS builds IIRC; it doesn't seem like there's much urgency in getting it buildable using tools available to non-Meta-employees.
