Scalar is a repository management tool that optimizes Git for use in large repositories. Scalar improves performance by configuring advanced Git settings, maintaining repositories in the background, and helping to reduce data sent across the network.
An important Scalar concept is the enlistment: this is the top-level directory of the project. It usually contains the subdirectory src/ which is a Git worktree. This encourages the separation between tracked files (inside src/) and untracked files, such as build artifacts (outside src/). When registering an existing Git worktree with Scalar whose name is not src, the enlistment will be identical to the worktree.
The scalar command implements various subcommands, and different options depending on the subcommand. With the exception of clone, list and reconfigure --all, all subcommands expect to be run in an enlistment.
The following options can be specified before the subcommand:
-C <directory>
-c <key>=<value>
COMMANDS
Clone
clone [<options>] <url> [<enlistment>]
The sparse-checkout feature is enabled (except when run with --full-clone) and the only files present are those in the top-level directory. Use git sparse-checkout set to expand the set of directories you want to see, or git sparse-checkout disable to expand to all files (see git-sparse-checkout(1) for more details). You can explore the subdirectories outside your sparse-checkout by using git ls-tree HEAD[:<directory>].
-b <name>, --branch <name>
--[no-]single-branch
Further fetches into the resulting repository will only update the remote-tracking branch for the branch this option was used for the initial cloning. If the HEAD at the remote did not point at any branch when --single-branch clone was made, no remote-tracking branch is created.
--[no-]src
--[no-]tags
--[no-]full-clone
List
list
Register
register [<enlistment>]
Note: when this subcommand is called in a worktree that is called src/, its parent directory is considered to be the Scalar enlistment. If the worktree is not called src/, it itself will be considered to be the Scalar enlistment.
Unregister
unregister [<enlistment>]
Run
scalar run ( all | config | commit-graph | fetch | loose-objects | pack-files ) [<enlistment>]
These tasks are run automatically as part of the scheduled maintenance, as soon as the repository is registered with Scalar. It should therefore not be necessary to run this subcommand manually.
The config task is specific to Scalar and configures all those opinionated default settings that make Git work more efficiently with large repositories. As this task is run as part of scalar clone automatically, explicit invocations of this task are rarely needed.
Reconfigure
After a Scalar upgrade, or when the configuration of a Scalar enlistment was somehow corrupted or changed by mistake, this subcommand allows to reconfigure the enlistment.
With the --all option, all enlistments currently registered with Scalar will be reconfigured. Use this option after each Scalar upgrade.
Diagnose
diagnose [<enlistment>]
The output of this command is a .zip file that is written into a directory adjacent to the worktree in the src directory.
Delete
delete <enlistment>
