一个可扩展、用户友好的源代码控制系统。
Sapling SCM is a cross-platform, highly scalable, Git-compatible source control system.
It aims to provide both user-friendly and powerful interfaces for users, as well as extreme scalability to deal with repositories containing many millions of files and many millions of commits.
To start using Sapling, see the Getting Started page for how to clone your existing Git repositories. Checkout the Overview for a peek at the various features. Coming from Git? Checkout the Git Cheat Sheet.
Sapling also comes with an Interactive Smartlog (ISL) web UI for seeing and interacting with your repository, as well as a VS Code integrated Interactive Smartlog.
Sapling SCM is comprised of three main components:
sl command line and web interface for users to interact
with Sapling SCM.Sapling SCM's scalability goals are to ensure that all source control operations scale with the number of files in use by a developer, and not with the size of the repository itself. This enables fast, performant developer experiences even in massive repositories with millions of files and extremely long commit histories.
The Sapling CLI, sl, was originally based on
Mercurial, and shares various aspects of the UI
and features of Mercurial.
The CLI code can be found in the eden/scm subdirectory.
Mononoke is the server-side component of Sapling SCM.
While it is used in production within Meta it is not yet supported for external usage. OSS builds in GitHub Actions are available for unsupported experimentation.
EdenFS is a virtual file system for managing Sapling checkouts.

EdenFS speeds up operations in large repositories by only populating working
directory files on demand, as they are accessed. This makes operations like
checkout much faster, in exchange for a small performance hit when first
accessing new files. This is quite beneficial in large repositories where
developers often only work with a small subset of the repository at a time.
More detailed EdenFS design documentation can be found at eden/fs/docs/Overview.md.
The Sapling CLI currently builds and runs on Linux, Mac, and Windows. It can be
built by running make oss in the eden/scm directory and running the
resulting sl executable.
Building the Sapling CLI requires Python 3.8, Rust, CMake, and OpenSSL for the main cli, and Node and Yarn for the ISL web UI.
