tog — Git repository browser

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


tog path

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:

Display usage information.
, --version
Display program version and exit immediately.

The global key bindings are:

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.
Quit tog.
Quit the view which is in focus.
Switch focus between views.
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.
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).
Go to line N in the view (default: last line).
Go to line N in the view (default: first line).

The commands for tog are as follows:

[-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 (N denotes optional prefixed count modifier):

Move the selection cursor down N lines (default: 1).
Move the selection cursor up N lines (default: 1).
Scroll log message field to the right N increments (default: 1).
Log message moves left on the screen.
Scroll log message field to the left N increments (default: 1).
Log message moves right on the screen.
Scroll log message field to the rightmost position.
Scroll log message field to the leftmost position.
Move the selection cursor down N pages (default: 1).
Move the selection cursor up N pages (default: 1).
Move the selection cursor down N half pages (default: 1).
Move the selection cursor up N half pages (default: 1).
Move the cursor to the newest commit.
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.
Move the cursor to commit N (default: 1).
Like g but defaults to the oldest commit.
Open a diff view showing file changes made in the currently selected commit.
Open a tree view showing the tree for the currently selected commit.
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).
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.
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.
Reload the log view with new commits found in the repository.
Reload the log view and toggle display of merged commits. The -b option determines whether merged commits are displayed initially.
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:

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.
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.
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.
[-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, or an object ID SHA1 hash, 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 key bindings for tog diff are as follows (N denotes optional prefixed count modifier):

Navigate to the Nth next file in the diff (default: 1).
Navigate to the Nth previous hunk in the diff (default: 1).
Navigate to the Nth next hunk in the diff (default: 1).
Reduce diff context by N lines (default: 1).
Increase diff context by N lines (default: 1).
If the diff view was opened via the log view, move to the Nth previous (younger) commit. If the diff was opened via the blame view, move to the Nth previous line and load the corresponding commit (default: 1).
If the diff view was opened via the log view, move to the Nth next (older) commit. If the diff was opened via the blame view, move to the Nth next line and load the corresponding commit (default: 1).

tog shows colorized output if this variable is set to a non-empty value. The default color scheme can be modified by setting the environment variables documented below. The colors available in color schemes are “black”, “red”, “green”, “yellow”, “blue”, “magenta”, “cyan”, and “default” which maps to the terminal's default foreground color.
The color used to mark up author information. If not set, the default value “cyan” is used.
The color used to mark up commit IDs. If not set, the default value “green” is used.
The color used to mark up date information. If not set, the default value “yellow” is used.
The color used to mark up chunk header lines in diffs. If not set, the default value “yellow” is used.
The color used to mark up meta data in diffs. If not set, the default value “green” is used.
The color used to mark up removed lines in diffs. If not set, the default value “magenta” is used.
The color used to mark up added lines in diffs. If not set, the default value “cyan” is used.
The color used to mark up references in the “refs/got/backup/” namespace. If not set, the default value “cyan” is used.
The color used to mark up references in the “refs/heads/” namespace. If not set, the default value “green” is used.
The color used to mark up references in the “refs/remotes/” namespace. If not set, the default value “yellow” is used.

The color used to mark up submodule tree entries. If not set, the default value “magenta” is used.
The color used to mark up symbolic link tree entries. If not set, the default value “magenta” is used.
Determines the default diff algorithm used by tog. Supported diff algorithms are Myers (quick and dirty) and Patience (slow and tidy). Valid values for TOG_DIFF_ALGORITHM are “patience” and “myers”. If unset, the Myers diff algorithm will be used by default.
Determines the default layout of split-screen views. If set to “h” or “H”, tog will use horizontal split by default. Otherwise, vertical split will be used. The S key can be used to switch between vertical and horizontal split layout at run-time.

The tog utility exits 0 on success, and >0 if an error occurs.
