.Sh NAME
.Nm got
.Nd game of trees
.Sh SYNOPSIS
.Nm
.Ar command
.Op Fl h
.Op Ar arg ...
.Sh DESCRIPTION
.Nm
is a version control system which stores the history of tracked files
in a Git repository, as used by the Git version control system.
This repository format is described in
.Xr git-repository 5 .
.Pp
.Nm
is a
.Dq 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 this 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 last component of
.Ar repository path ,
or if a
.Ar path prefix
was specified use the last component of
.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 .
If this option is not specified, a commit resolved via the repository's HEAD
reference will be 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 ] [ Ar path ]
Update an existing work tree to another commit on the current branch.
By default, the latest commit on the current branch is assumed.
Show the status of each affected file, using the following status codes:
.Bl -column YXZ description
.It U Ta file was updated and contained no local changes
.It G Ta file was updated and local changes were merged cleanly
.It C Ta file was updated and conflicts occurred during merge
.It D Ta file was deleted
.It A Ta new file was added
.It ~ Ta versioned file is obstructed by a non-regular file
.It ! Ta a missing versioned file was restored
.El
.Pp
If a
.Ar path
is specified, restrict the update operation to files at or within this path.
The path is required to exist in the update operation's target commit.
Files in the work tree outside this path will remain unchanged and will
retain their previously recorded base commit.
Some
.Nm
commands may refuse to run while the work tree contains files from
multiple base commits.
The base commit of such a work tree can be made consistent by running
another update operation across the entire work tree.
.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 [ Ar path ]
Show the current modification status of files in a work tree,
using the following status codes:
.Bl -column YXZ description
.It M Ta modified file
.It A Ta file scheduled for addition in next commit
.It D Ta file scheduled for deletion in next commit
.It C Ta modified or added file which contains merge conflicts
.It ! Ta versioned file was expected on disk but is missing
.It ~ Ta versioned file is obstructed by a non-regular file
.It ? Ta unversioned item not tracked by
.Nm
.El
.Pp
If a
.Ar path
is specified, only show modifications within this path.
.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.
If this directory is a
.Nm
work tree, use the repository path associated with this work tree.
.El
.It Cm diff [ Fl C Ar number ] [ Fl r Ar repository-path ] [ Ar object1 Ar object2 | Ar path ]
When invoked within a work tree with less than two arguments, display
uncommitted changes in the work tree.
If a
.Ar path
is specified, only show changes within this path.
.Pp
If two arguments are provided, treat each argument as a SHA1 hash which
corresponds to an object in the repository, and display differences
between these objects.
Both objects must be of the same type (blobs, trees, or commits).
.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.
.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.
If this directory is a
.Nm
work tree, use the repository path associated with this work tree.
.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.
If this directory is a
.Nm
work tree, use the repository path associated with this work tree.
.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.
Entries shown in this listing may carry one of the following trailing
annotations:
.Bl -column YXZ description
.It / Ta entry is a directory
.It * Ta entry is an executable file
.El
.Pp
If no
.Ar path
is specified, list the repository path corresponding to the current
directory of the work tree, or the root directory of the repository
if there is no work tree.
.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 .

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.
If this directory is a
.Nm
work tree, use the repository path associated with this work tree.
.It Fl i
Show object IDs of files (blob objects) and directories (tree objects).
.It Fl R
Recurse into sub-directories in the repository.
.El
.It Cm ref [ Fl r Ar repository-path ] [ Fl l ] [ Fl d Ar name ] [ Ar name Ar object ]

.El
.It Cm add Ar file-path
Schedule an unversioned file in a work tree for addition to the
repository in the next commit.

changes back after
.Cm got revert !
.Pp
If the file was added with
.Cm got add
