<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph">
<p>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.</p>
</div>
<div class="paragraph">
<p>An important Scalar concept is the enlistment: this is the top-level directory
of the project. It usually contains the subdirectory <code>src/</code> which is a Git
worktree. This encourages the separation between tracked files (inside <code>src/</code>)
and untracked files, such as build artifacts (outside <code>src/</code>). When registering
an existing Git worktree with Scalar whose name is not <code>src</code>, the enlistment
will be identical to the worktree.</p>
</div>
<div class="paragraph">
<p>The <code>scalar</code> command implements various subcommands, and different options
depending on the subcommand. With the exception of <code>clone</code>, <code>list</code> and
<code>reconfigure</code> <code>--all</code>, all subcommands expect to be run in an enlistment.</p>
</div>
<div class="paragraph">
<p>The following options can be specified <em>before</em> the subcommand:</p>
</div>
<div class="dlist">
<dl>
<dt class="hdlist1">-C &lt;directory&gt;</dt>
<dd>
<p>Before running the subcommand, change the working directory. This
option imitates the same option of <a href="git.html">git(1)</a>.</p>
</dd>
<dt class="hdlist1">-c &lt;key&gt;=&lt;value&gt;</dt>
<dd>
<p>For the duration of running the specified subcommand, configure this
setting. This option imitates the same option of <a href="git.html">git(1)</a>.</p>
</dd>
</dl>
</div>
</div>
</div>
<div class="sect1">
<h2 id="_commands">COMMANDS</h2>
<div class="sectionbody">
<div class="sect2">
<h3 id="_clone">Clone</h3>
<div class="dlist">
<dl>
<dt class="hdlist1">clone [&lt;options&gt;] &lt;url&gt; [&lt;enlistment&gt;]</dt>
<dd>
<p>Clones the specified repository, similar to <a href="git-clone.html">git-clone(1)</a>. By
default, only commit and tree objects are cloned. Once finished, the
worktree is located at <em>&lt;enlistment&gt;</em><code>/src</code>.</p>
<div class="paragraph">
<p>The sparse-checkout feature is enabled (except when run with <code>--full-clone</code>)
and the only files present are those in the top-level directory. Use
<code>git</code> <code>sparse-checkout</code> <code>set</code> to expand the set of directories you want to see,
or <code>git</code> <code>sparse-checkout</code> <code>disable</code> to expand to all files (see
<a href="git-sparse-checkout.html">git-sparse-checkout(1)</a> for more details). You can explore the
subdirectories outside your sparse-checkout by using <code>git</code> <code>ls-tree</code>
<code>HEAD</code>[<code>:</code><em>&lt;directory&gt;</em>].</p>
</div>
</dd>
<dt class="hdlist1">-b &lt;name&gt;</dt>
<dt class="hdlist1">--branch &lt;name&gt;</dt>
<dd>
<p>Instead of checking out the branch pointed to by the cloned
repository&#8217;s HEAD, check out the <em>&lt;name&gt;</em> branch instead.</p>
</dd>
<dt class="hdlist1">--[no-]single-branch</dt>
<dd>
<p>Clone only the history leading to the tip of a single branch, either
specified by the <code>--branch</code> option or the primary branch remote&#8217;s
<code>HEAD</code> points at.</p>
<div class="paragraph">
<p>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
<code>--single-branch</code> clone was made, no remote-tracking branch is created.</p>
</div>
</dd>
<dt class="hdlist1">--[no-]src</dt>
<dd>
<p>By default, <code>scalar</code> <code>clone</code> places the cloned repository within a
<em>&lt;entlistment&gt;</em><code>/src</code> directory. Use <code>--no-src</code> to place the cloned
repository directly in the <em>&lt;enlistment&gt;</em> directory.</p>
</dd>
<dt class="hdlist1">--[no-]tags</dt>
<dd>
<p>By default, <code>scalar</code> <code>clone</code> will fetch the tag objects advertised by
the remote and future <code>git</code> <code>fetch</code> commands will do the same. Use
<code>--no-tags</code> to avoid fetching tags in <code>scalar</code> <code>clone</code> and to configure
the repository to avoid fetching tags in the future. To fetch tags after
cloning with <code>--no-tags</code>, run <code>git</code> <code>fetch</code> <code>--tags</code>.</p>
</dd>
<dt class="hdlist1">--[no-]full-clone</dt>
<dd>
<p>A sparse-checkout is initialized by default. This behavior can be
turned off via <code>--full-clone</code>.</p>
</dd>
</dl>
</div>
</div>
<div class="sect2">
<h3 id="_list">List</h3>
<div class="dlist">
<dl>
<dt class="hdlist1">list</dt>
<dd>
<p>List enlistments that are currently registered by Scalar. This
subcommand does not need to be run inside an enlistment.</p>
</dd>
</dl>
</div>
</div>
<div class="sect2">
<h3 id="_register">Register</h3>
<div class="dlist">
<dl>
<dt class="hdlist1">register [&lt;enlistment&gt;]</dt>
<dd>
<p>Adds the enlistment&#8217;s repository to the list of registered repositories
and starts background maintenance. If <em>&lt;enlistment&gt;</em> is not provided,
then the enlistment associated with the current working directory is
registered.</p>
<div class="paragraph">
<p>Note: when this subcommand is called in a worktree that is called <code>src/</code>, its
parent directory is considered to be the Scalar enlistment. If the worktree is
<em>not</em> called <code>src/</code>, it itself will be considered to be the Scalar enlistment.</p>
</div>
</dd>
</dl>
</div>
</div>
<div class="sect2">
<h3 id="_unregister">Unregister</h3>
<div class="dlist">
<dl>
<dt class="hdlist1">unregister [&lt;enlistment&gt;]</dt>
<dd>
<p>Remove the specified repository from the list of repositories
registered with Scalar and stop the scheduled background maintenance.</p>
</dd>
</dl>
</div>
</div>
<div class="sect2">
<h3 id="_run">Run</h3>
<div class="dlist">
<dl>
<dt class="hdlist1">scalar run ( all | config | commit-graph | fetch | loose-objects | pack-files ) [&lt;enlistment&gt;]</dt>
<dd>
<p>Run the given maintenance task (or all tasks, if <code>all</code> was specified).
Except for <code>all</code> and <code>config</code>, this subcommand simply hands off to
<a href="git-maintenance.html">git-maintenance(1)</a> (mapping <code>fetch</code> to <code>prefetch</code> and
<code>pack-files</code> to <code>incremental-repack</code>).</p>
<div class="paragraph">
<p>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.</p>
</div>
<div class="paragraph">
<p>The <code>config</code> 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 <code>scalar</code> <code>clone</code>
automatically, explicit invocations of this task are rarely needed.</p>
</div>
</dd>
</dl>
</div>
</div>
<div class="sect2">
<h3 id="_reconfigure">Reconfigure</h3>
<div class="paragraph">
<p>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.</p>
</div>
<div class="paragraph">
<p>With the <code>--all</code> option, all enlistments currently registered with Scalar
will be reconfigured. Use this option after each Scalar upgrade.</p>
</div>
</div>
<div class="sect2">
<h3 id="_diagnose">Diagnose</h3>
<div class="dlist">
<dl>
<dt class="hdlist1">diagnose [&lt;enlistment&gt;]</dt>
<dd>
<p>When reporting issues with Scalar, it is often helpful to provide the
information gathered by this command, including logs and certain
statistics describing the data shape of the current enlistment.</p>
<div class="paragraph">
<p>The output of this command is a .<code>zip</code> file that is written into
a directory adjacent to the worktree in the <code>src</code> directory.</p>
</div>

<div class="sect2">
<h3 id="_delete">Delete</h3>
<div class="dlist">

<p>This subcommand lets you delete an existing Scalar enlistment from your
local file system, unregistering the repository.</p>
