TOG(1)

NAME
tog - Git repository browser

SYNOPSIS
tog [command] [-h] [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.

tog provides global and command-specific key bindings and options. The global key bindings are:

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 split-screen views if the size of the terminal window is sufficiently large.

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

-h  Display usage information.

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

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.

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

    The key bindings for tog log are as follows:

    Down-arrow, j, >, Full stop
        Move the selection cursor down.

    Up-arrow, k, <, Comma
        Move the selection cursor up.

    Page-down, Ctrl+f
        Move the selection cursor down one page.

    Page-up, Ctrl+b
        Move the selection cursor up one page.

    Enter, Space
        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, unless an active search is in progress in which case Backspace aborts the search.

    /   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).

    n   Find the next commit which matches the current search pattern. Searching continues until either a match is found or the Backspace key is pressed.

    N   Find the previous commit which matches the current search pattern. Searching continues until either a match is found 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.

    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 the name of a branch or a commit ID SHA1 hash. An abbreviated hash argument will be expanded to a full SHA1 hash automatically, provided the abbreviation is unique. If this option is not specified, default to the work tree's current branch if invoked in a work tree, or to the repository's HEAD reference.

    -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 [-r repository-path] object1 object2
    Display the differences between two objects in the repository. Each object argument is an object ID SHA1 hash. An abbreviated hash argument will be expanded to a full SHA1 hash automatically, provided the abbreviation is unique. Both objects must be of the same type (blobs, trees, or commits).

    The key bindings for tog diff are as follows:

    Down-arrow, j
        Scroll down.

    Up-arrow, k
        Scroll up.

    Page-down, Space, Ctrl+f
        Scroll down one page.

    Page-up, Ctrl+b
        Scroll up one page.

    [   Reduce the amount of diff context lines.

    ]   Increase the amount of diff context lines.

    <, Comma
        If the diff view was opened via the log view, move to the previous (younger) commit.

    >, Full stop
        If the diff view was opened via the log view, move to the next (older) commit.

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

    n   Find the next line which matches the current search pattern.

    N   Find the previous line which matches the current search pattern.

    The options for tog diff are as follows:

    -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.

blame [-c commit] [-r repository-path] path
    Display line-by-line history of a file at the specified path.

    The key bindings for tog blame are as follows:

    Down-arrow, j
        Move the selection cursor down.

    Up-arrow, k
        Move the selection cursor up.

    Page-down, Space, Ctrl+f
        Move the selection cursor down one page.

    Page-up, Ctrl+b
        Move the selection cursor up one page.

    Enter
        Open a diff view for the currently selected line's commit.

    b   Reload the blame view with the version of the file as found in the currently selected line's commit.

    p   Reload the blame view with the version of the file as found in the parent commit of the currently selected line's commit.

    B   Reload the blame view with the previously blamed commit.

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

    n   Find the next line which matches the current search pattern.

    N   Find the previous line which matches the current search pattern.

    The options for tog blame are as follows:

    -c commit
        Start traversing history at the specified commit. The expected argument is the name of a branch or a commit ID SHA1 hash. An abbreviated hash argument will be expanded to a full SHA1 hash automatically, provided the abbreviation is unique.

    -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.

tree [-c commit] [-r repository-path] [path]
    Display the repository tree. If a path is specified, show tree entries at this path.

    Displayed tree entries may carry one of the following trailing annotations:
    @ | entry is a symbolic link
    / | entry is a directory
    * | entry is an executable file
    $ | entry is a Git submodule

    Symbolic link entries are also annotated with the target path of the link.

    The key bindings for tog tree are as follows:

    Down-arrow, j
        Move the selection cursor down.

    Up-arrow, k
        Move the selection cursor up.

    Page-down, Ctrl+f
        Move the selection cursor down one page.

    Page-up, Ctrl+b
        Move the selection cursor up one page.

    Enter
        Enter the currently selected directory, or switch to the blame view for the currently selected file.

    l   Open a log view for the currently selected tree entry.

    Backspace
        Move back to the parent directory.

    i   Show object IDs for all objects displayed in the tree view.

    /   Prompt for a search pattern and start searching for matching tree entries. The search pattern is an extended regular expression which is matched against the tree entry's name. Regular expression syntax is documented in re_format(7).

    n   Find the next tree entry which matches the current search pattern.

    N   Find the previous tree entry which matches the current search pattern.

    The options for tog tree are as follows:

    -c commit
        Start traversing history at the specified commit. The expected argument is the name of a branch or a commit ID SHA1 hash. An abbreviated hash argument will be expanded to a full SHA1 hash automatically, provided the abbreviation is unique.

    -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.
