NAME
tog - Git repository browser

SYNOPSIS
tog [-hV] command [arg ...]

tog path

DESCRIPTION
tog is an interactive read-only browser for Git repositories. This repository format is described in git-repository(5).

tog supports several types of views which display repository data:

Log view
    Displays commits in the repository's history. This view is displayed initially if no command is specified, or if just a path is specified.

Diff view
    Displays changes made in a particular commit.

Blame view
    Displays the line-by-line history of a file.

Tree view
    Displays the tree corresponding to a particular commit.

Ref view
    Displays references in the repository.

tog provides global and command-specific key bindings and options. Some command-specific key bindings may be prefixed with an integer, which is denoted by N in the descriptions below, and is used as a modifier to the operation as indicated. tog will echo digits to the screen when count modifiers are entered, and complete the sequence upon input of the first non-numeric character. Count modifiers can be aborted by entering an unmapped key. Once a compound command is executed, the operation can be cancelled with C-g or Backspace.

Global options must precede the command name, and are as follows:

-h  Display usage information.

-V, --version
    Display program version and exit immediately.

The global key bindings are:

H, F1
    Display run-time help. Key bindings for the focussed view will be displayed. Pressing this again inside the help view will toggle the display of key bindings for all tog views.

Q   Quit tog.

q   Quit the view which is in focus.

Tab Switch focus between views.

F   Toggle fullscreen mode for a split-screen view. tog will automatically use vertical split-screen views if the size of the terminal window is sufficiently large.

S   Switch the current split-screen layout, and render all active views in this new layout. The split-screen layout can be either vertical or horizontal. If the terminal is not wide enough when switching to a vertical split, views will render in fullscreen.

-   When in a split-screen view, decrease the size of the focussed split N increments (default: 1).

+   When in a split-screen view, increase the size of the focussed split N increments (default: 1).

G   Go to line N in the view (default: last line).

g   Go to line N in the view (default: first line).

Right-arrow, l
    Scroll view to the right N increments (default: 1).
    Output moves left on the screen.

Left-arrow, h
    Scroll view to the left N increments (default: 1).
    Output moves right on the screen.

$   Scroll view to the rightmost position.

0   Scroll view left to the start of the line.

The commands for tog are as follows:

    log [-b] [-c commit] [-r repository-path] [path] Display history of a repository. If a path is specified, show only commits which modified this path. If invoked in a work tree, the path is interpreted relative to the current working directory, and the work tree's path prefix is implicitly prepended. Otherwise, the path is interpreted relative to the repository root.

    If invoked in a work tree, the log entry of the work tree's base commit will be prefixed with one of the following annotations:
    * | work tree's base commit and the base commit of all tracked files
    matches the branch tip
    ~ | work tree comprises mixed commits or its base commit is out-of-date

    This command is also executed if no explicit command is specified.

    The key bindings for tog log are as follows (N denotes optional prefixed count modifier):

    Down-arrow, j, >, Full stop, Ctrl-n
        Move the selection cursor down N lines (default: 1).

    Up-arrow, k, <, Comma, Ctrl-p
        Move the selection cursor up N lines (default: 1).

    Page-down, Space, Ctrl+f, f
        Move the selection cursor down N pages (default: 1).

    Page-up, Ctrl+b, b
        Move the selection cursor up N pages (default: 1).

    Ctrl+d, d
        Move the selection cursor down N half pages (default: 1).

    Ctrl+u, u
        Move the selection cursor up N half pages (default: 1).

    Home, =
        Move the cursor to the newest commit.

    End, *
        Move the cursor to the oldest commit. This will traverse all commits on the current branch which may take a long time depending on the number of commits in branch history. If needed, this operation can be cancelled with C-g or Backspace.

    g   Move the cursor to commit N (default: 1).

    G   Like g but defaults to the oldest commit.

    Enter
        Open a diff view showing file changes made in the currently selected commit.

    T   Open a tree view showing the tree for the currently selected commit.

    Backspace
        Show log entries for the parent directory of the currently selected path. However when an active search is in progress or when additional commits are loaded, Backspace aborts the running operation.

    /   Prompt for a search pattern and start searching for matching commits. The search pattern is an extended regular expression which is matched against a commit's author name, committer name, log message, and commit ID SHA1 hash. Regular expression syntax is documented in re_format(7).

    &   Prompt for a pattern and limit the log view's list of commits to those which match the pattern. If no pattern is specified, i.e. the & prompt is immediately closed with the Enter key, then the pattern is cleared. Until the pattern is cleared, the limited list of commits replaces the full list of commits for all operations supported by the log view. For example, a search started with / will search the limited list of commits, rather than searching all commits. The pattern is an extended regular expression which is matched against a commit's author name, committer name, log message, and commit ID SHA1 hash. Regular expression syntax is documented in re_format(7).

    n   Find the Nth next commit which matches the current search pattern (default: 1).
        Searching continues until either a match is found or C-g or the Backspace key is pressed.

    N   Find the Nth previous commit which matches the current search pattern (default: 1).
        Searching continues until either a match is found or C-g or the Backspace key is pressed.

    Ctrl+l
        Reload the log view with new commits found in the repository.

    B   Reload the log view and toggle display of merged commits. The -b option determines whether merged commits are displayed initially.

    R   Open a ref view listing all references in the repository. This can then be used to open a new log view for arbitrary branches and tags.

    @   Toggle between showing the committer name and the author name.

    The options for tog log are as follows:

    -b  Display individual commits which were merged into the current branch from other branches. By default, tog log shows the linear history of the current branch only. The B key binding can be used to toggle display of merged commits at run-time.

    -c commit
        Start traversing history at the specified commit. The expected argument is a commit ID SHA1 hash, or a reference name or keyword which will be resolved to a commit ID. An abbreviated hash argument will be expanded to a full SHA1 hash automatically, provided the abbreviation is unique. The keywords ":base" and ":head" resolve to the work tree's base commit and branch head, respectively. The former is only valid if invoked in a work tree, while the latter will resolve to the tip of the work tree's current branch if invoked in a work tree, otherwise it will resolve to the repository's HEAD reference. Keywords and references may be appended with ":+" or ":-" modifiers and an optional integer N to denote the Nth descendant or antecedent by first parent traversal, respectively; for example, :head:-2 denotes the work tree branch head's 2nd generation ancestor, and :base:+4 denotes the 4th generation descendant of the work tree's base commit. Similarly, foobar:+3 will denote the 3rd generation descendant of the commit resolved by the "foobar" reference. A ":+" or ":-" modifier without a trailing integer has an implicit "1" appended (e.g., :base:+ is equivalent to :base:+1).

    -r 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 got(1) work tree, use the repository path associated with this work tree.

    diff [-aw] [-C number] [-r repository-path] object1 object2 Display the differences between two objects in the repository. Treat each of the two arguments as a reference, a tag name, an object ID SHA1 hash, or a keyword and display differences between the corresponding objects. Both objects must be of the same type (blobs, trees, or commits). An abbreviated hash argument will be expanded to a full SHA1 hash automatically, provided the abbreviation is unique. The keywords ":base" and ":head" resolve to the work tree's base commit and branch head, respectively. The former is only valid if invoked in a work tree, while the latter will resolve to the tip of the work tree's current branch if invoked in a work tree, otherwise it will resolve to the repository's HEAD reference. Keywords and references may be appended with ":+" or ":-" modifiers and an optional integer N to denote the Nth descendant or antecedent by first parent traversal, respectively; for example, :head:-2 denotes the work tree branch head's 2nd generation ancestor, and :base:+4 denotes the 4th generation descendant of the work tree's base commit. Similarly, foobar:+3 will denote the 3rd generation descendant of the commit resolved by the "foobar" reference. A ":+" or ":-" modifier without a trailing integer has an implicit "1" appended (e.g., :base:+ is equivalent to :base:+1).

    -C number
        Set the number of context lines shown in the diff. By default, 3 lines of context are shown.

    -r repository-path

    C   Reload the blame view with the previously blamed commit.

    L   Open a log view for the currently selected annotated line.

    /   Prompt for a search pattern and start searching for matching lines. The search pattern is an extended regular expression. Regular expression syntax is documented in re_format(7).

    n   Find the Nth next line which matches the current search pattern (default: 1).

    N   Find the Nth previous line which matches the current search pattern (default: 1).
