.Sh NAME
.Nm got
.Nd version control system
.Sh SYNOPSIS
.Nm
.Ar command
.Op Fl h
.Op Ar arg ...
.Sh DESCRIPTION
.Nm
is a version control system which prioritizes ease of use and simplicity
over flexibility.
.Pp
.Nm
stores the history of tracked files in a repository which uses
the same on-disk format as
.Dq bare
repositories used by the Git version control system.
This repository format is described in
.Xr git-repository 5 .
.Pp
.Nm
is a
.Em distributed
version control system because every copy of a repository is writeable.
Modifications made to files can be synchronized between repositories
at any time.
.Pp
Files managed by
.Nm
must be checked out from the repository for modification.
Checked out files are stored in a
.Em work tree
which can be placed at an arbitrary directory in the filesystem hierarchy.
The on-disk format of a
.Nm
work tree is described in
.Xr got-worktree 5 .
.Pp
.Nm
provides global and command-specific options.
Global options must preceed the command name, and are as follows:
.Bl -tag -width tenletters
.It Fl h
Display usage information.
.El
.Pp
The commands for
.Nm
are as follows:
.Bl -tag -width checkout
.It Cm checkout [ Fl c Ar commit ] [ Fl p Ar path-prefix ] repository-path [ work-tree-path ]
Copy files from a repository into a new work tree.
If the
.Ar work tree path
is not specified, either use the base name of the
.Ar repository path ,
or if a
.Ar path prefix
was specified use the base name of the
.Ar path prefix .
.Pp
The options for
.Cm got checkout
are as follows:
.Bl -tag -width Ds
.It Fl c Ar commit
Check out files from the specified
.Ar commit .
By default, the HEAD commit is used.
.It Fl p Ar path-prefix
Restrict the work tree to a subset of the repository's tree hierarchy.
Only files beneath the specified
.Ar path-prefix
will be checked out.
.El
.It Cm update [ Fl c Ar commit ] [ work-tree-path ]
Update an existing work tree to another commit on the current branch.
By default, the latest commit on the current branch is assumed.
If the
.Ar work tree path
is omitted, use the current working directory.
.Pp
The options for
.Cm got update
are as follows:
.Bl -tag -width Ds
.It Fl c Ar commit
Update the work tree to the specified
.Ar commit .
The expected argument is a SHA1 hash which corresponds to a commit object.
.El
.\".It Cm status
.\"Show current status of files.
.It Cm log [ Fl c Ar commit ] [ Fl C Ar number ] [ Fl f ] [ Fl l Ar N ] [ Fl p ] [ Fl r Ar repository-path ] [ path ]
Display history of a repository.
If a
.Ar path
is specified, show only commits which modified this path.
.Pp
The options for
.Cm got log
are as follows:
.Bl -tag -width Ds
.It Fl c Ar commit
Start traversing history at the specified
.Ar commit .
The expected argument is the name of a branch or a SHA1 hash which corresponds
to a commit object.
.It Fl C Ar number
Set the number of context lines shown in diffs with
.Fl p .
By default, 3 lines of context are shown.
.It Fl f
Restrict history traversal to the first parent of each commit.
This shows the linear history of the current branch only.
Merge commits which affected the current branch will be shown but
individual commits which originated on other branches will be omitted.
.It Fl l Ar N
Limit history traversal to a given number of commits.
.It Fl p
Display the patch of modifications made in each commit.
.It Fl r Ar repository-path
Use the repository at the specified path.
If not specified, assume the repository is located at or above the current
working directory.
.El
.It Cm diff [ Fl C Ar number ] [ Ar repository-path ] Ar object1 Ar object2
Display the differences between two objects in the repository.
Each
.Ar object
argument is a SHA1 hash which corresponds to the object.
Both objects must be of the same type (blobs, trees, or commits).
If the
.Ar repository path
is omitted, use the current working directory.
.Pp
The options for
.Cm got diff
are as follows:
.Bl -tag -width Ds
.It Fl C Ar number
Set the number of context lines shown in the diff.
By default, 3 lines of context are shown.
.El
.It Cm blame [ Fl c Ar commit ] [ Fl r Ar repository-path ] Ar path
Display line-by-line history of a file at the specified path.
.Pp
The options for
.Cm got blame
are as follows:
.Bl -tag -width Ds
.It Fl c Ar commit
Start traversing history at the specified
.Ar commit .
The expected argument is the name of a branch or a SHA1 hash which corresponds
to a commit object.
.It Fl r Ar repository-path
Use the repository at the specified path.
If not specified, assume the repository is located at or above the current
working directory.
.El
.It Cm tree [ Fl c Ar commit ] [ Fl r Ar repository-path ] [ Fl i ] [ Fl R] [ Ar path ]
Display a listing of files and directories at the specified
directory path in the repository.
If no path is specified, the root directory is listed.
.Pp
The options for
.Cm got tree
are as follows:
.Bl -tag -width Ds
.It Fl c Ar commit
List files and directories as they appear in the specified
.Ar commit .
The expected argument is the name of a branch or a SHA1 hash which corresponds
to a commit object.
.It Fl r Ar repository-path
Use the repository at the specified path.
If not specified, assume the repository is located at or above the current
working directory.
.It Fl i
Show object IDs of files (blob objects) and directories (tree objects).
.It Fl R
Recurse into sub-directories.
.El

Check out a work tree of
.Ox
kernel sources from a Git repository at /var/repo/openbsd-src to ~/sys:
