30 .Sh DESCRIPTION
31 .Nm
32 is an interactive read-only browser for Git repositories.
33 This repository format is described in
34 .Xr git-repository 5 .
35 .Pp
36 .Nm
37 supports several types of views which display repository data:
38 .Bl -tag -width Ds
39 .It Log view
40 Displays commits in the repository's history.
41 This view is displayed initially if no
42 .Ar command
43 is specified, or if just a
44 .Ar path
45 is specified.
46 .It Diff view
47 Displays changes made in a particular commit.
48 .It Blame view
49 Displays the line-by-line history of a file.
50 .It Tree view
51 Displays the tree corresponding to a particular commit.
52 .It Ref view
53 Displays references in the repository.
54 .El
55 .Pp
56 .Nm
57 provides global and command-specific key bindings and options.
58 Some command-specific key bindings may be prefixed with an integer, which is
59 denoted by N in the descriptions below, and is used as a modifier to the
60 operation as indicated.
61 .Nm
62 will echo digits to the screen when count modifiers are entered, and complete
63 the sequence upon input of the first non-numeric character.
64 Count modifiers can be aborted by entering an unmapped key.
65 Once a compound command is executed, the operation can be cancelled with
66 .Cm C-g
67 or
68 .Cm Backspace .
69 .Pp
70 Global options must precede the command name, and are as follows:
71 .Bl -tag -width tenletters
72 .It Fl h
73 Display usage information.
74 .It Fl V , -version
75 Display program version and exit immediately.
76 .El
77 .Pp
78 The global key bindings are:
79 .Bl -tag -width Ds
80 .It Cm H, F1
81 Display run-time help.
82 Key bindings for the focussed view will be displayed.
83 Pressing this again inside the help view will toggle the display of
84 key bindings for all
85 .Nm
86 views.
87 .It Cm Q
88 Quit
89 .Nm .
90 .It Cm q
91 Quit the view which is in focus.
92 .It Cm Tab
93 Switch focus between views.
94 .It Cm F
95 Toggle fullscreen mode for a split-screen view.
96 .Nm
97 will automatically use vertical split-screen views if the size of the
98 terminal window is sufficiently large.
99 .It Cm S
100 Switch the current split-screen layout, and render all active views in
101 this new layout.
102 The split-screen layout can be either vertical or horizontal.
103 If the terminal is not wide enough when switching to a vertical split,
104 views will render in fullscreen.
105 .It Cm -
106 When in a split-screen view, decrease the size of the focussed split
107 N increments (default: 1).
108 .It Cm +
109 When in a split-screen view, increase the size of the focussed split
110 N increments (default: 1).
111 .It Cm G
112 Go to line N in the view (default: last line).
113 .It Cm g
114 Go to line N in the view (default: first line).
115 .It Cm Right-arrow, l
116 Scroll view to the right N increments (default: 1).
117 .br
118 Output moves left on the screen.
119 .It Cm Left-arrow, h
120 Scroll view to the left N increments (default: 1).
121 .br
122 Output moves right on the screen.
123 .It Cm $
124 Scroll view to the rightmost position.
125 .It Cm 0

127 .El
128 .Pp
129 The commands for
130 .Nm
131 are as follows:
132 .Bl -tag -width blame
133 .It Xo
134 .Cm log
135 .Op Fl b
136 .Op Fl c Ar commit
137 .Op Fl r Ar repository-path
138 .Op Ar path
139 .Xc
140 Display history of a repository.
141 If a
142 .Ar path
143 is specified, show only commits which modified this path.
144 If invoked in a work tree, the
145 .Ar path
146 is interpreted relative to the current working directory,
147 and the work tree's path prefix is implicitly prepended.
148 Otherwise, the path is interpreted relative to the repository root.
149 .Pp
150 This command is also executed if no explicit command is specified.
151 .Pp
152 The key bindings for
153 .Cm tog log
154 are as follows (N denotes optional prefixed count modifier):
155 .Bl -tag -width Ds
156 .It Cm Down-arrow, j, >, Full stop, Ctrl-n
157 Move the selection cursor down N lines (default: 1).
158 .It Cm Up-arrow, k, <, Comma, Ctrl-p
159 Move the selection cursor up N lines (default: 1).
160 .It Cm Page-down, Space, Ctrl+f, f
161 Move the selection cursor down N pages (default: 1).
162 .It Cm Page-up, Ctrl+b, b
163 Move the selection cursor up N pages (default: 1).
164 .It Cm Ctrl+d, d
165 Move the selection cursor down N half pages (default: 1).
166 .It Cm Ctrl+u, u
167 Move the selection cursor up N half pages (default: 1).
168 .It Cm Home, =
169 Move the cursor to the newest commit.
170 .It Cm End, *
171 Move the cursor to the oldest commit.
172 This will traverse all commits on the current branch which may take
173 a long time depending on the number of commits in branch history.
174 If needed, this operation can be cancelled with
175 .Cm C-g
176 or
177 .Cm Backspace .
178 .It Cm g
179 Move the cursor to commit N (default: 1).
180 .It Cm G
181 Like
182 .Cm g
183 but defaults to the oldest commit.
184 .It Cm Enter
185 Open a
186 .Cm diff
187 view showing file changes made in the currently selected commit.
188 .It Cm T
189 Open a
190 .Cm tree
191 view showing the tree for the currently selected commit.
192 .It Cm Backspace
193 Show log entries for the parent directory of the currently selected path.
194 However when an active search is in progress or when additional commits
195 are loaded,
196 .Cm Backspace
197 aborts the running operation.
198 .It Cm /
199 Prompt for a search pattern and start searching for matching commits.
200 The search pattern is an extended regular expression which is matched
201 against a commit's author name, committer name, log message, and
202 commit ID SHA1 hash.
203 Regular expression syntax is documented in
204 .Xr re_format 7 .
205 .It Cm &
206 Prompt for a pattern and limit the log view's list of commits to those
207 which match the pattern.
208 If no pattern is specified, i.e. the
209 .Cm &
210 prompt is immediately closed with the Enter key, then the pattern is
211 cleared.
212 Until the pattern is cleared, the limited list of commits replaces the
213 full list of commits for all operations supported by the log view.
214 For example, a search started with
215 .Cm /
216 will search the limited list of commits, rather than searching all commits.
217 The pattern is an extended regular expression which is matched
218 against a commit's author name, committer name, log message, and
219 commit ID SHA1 hash.
220 Regular expression syntax is documented in
221 .Xr re_format 7 .
222 .It Cm n
223 Find the Nth next commit which matches the current search pattern (default: 1).
224 .br
225 Searching continues until either a match is found or
226 .Cm C-g
227 or the
228 .Cm Backspace
229 key is pressed.
230 .It Cm N
231 Find the Nth previous commit which matches the current search pattern
232 (default: 1).
233 .br
234 Searching continues until either a match is found or
235 .Cm C-g
236 or the
237 .Cm Backspace
238 key is pressed.
239 .It Cm Ctrl+l
240 Reload the
241 .Cm log
242 view with new commits found in the repository.
243 .It Cm B
244 Reload the
245 .Cm log
246 view and toggle display of merged commits.
247 The
248 .Fl b
249 option determines whether merged commits are displayed initially.
250 .It Cm R
251 Open a
252 .Cm ref
253 view listing all references in the repository.
254 This can then be used to open a new
255 .Cm log
256 view for arbitrary branches and tags.
257 .It Cm @
258 Toggle between showing the committer name and the author name.
259 .El
260 .Pp
261 The options for
262 .Cm tog log
263 are as follows:
264 .Bl -tag -width Ds
265 .It Fl b
266 Display individual commits which were merged into the current branch
267 from other branches.
268 By default,
269 .Cm tog log
270 shows the linear history of the current branch only.
271 The
272 .Cm B
273 key binding can be used to toggle display of merged commits at run-time.
274 .It Fl c Ar commit
275 Start traversing history at the specified
276 .Ar commit .
277 The expected argument is the name of a branch or a commit ID SHA1 hash.
278 An abbreviated hash argument will be expanded to a full SHA1 hash
279 automatically, provided the abbreviation is unique.
280 If this option is not specified, default to the work tree's current branch
281 if invoked in a work tree, or to the repository's HEAD reference.
282 .It Fl r Ar repository-path
283 Use the repository at the specified path.
284 If not specified, assume the repository is located at or above the current
285 working directory.
286 If this directory is a

294 .Op Fl r Ar repository-path
295 .Ar object1
296 .Ar object2
297 .Xc
298 Display the differences between two objects in the repository.
299 Treat each of the two arguments as a reference, a tag name, or an object
300 ID SHA1 hash, and display differences between the corresponding objects.
301 Both objects must be of the same type (blobs, trees, or commits).
302 An abbreviated hash argument will be expanded to a full SHA1 hash
303 automatically, provided the abbreviation is unique.
304 .Pp
305 The key bindings for
