7 mr - a Multiple Repository management tool
11 B<mr> [options] checkout
13 B<mr> [options] update
15 B<mr> [options] status
17 B<mr> [options] commit [-m "message"]
23 B<mr> [options] register [repository]
25 B<mr> [options] config section [parameter=[value] ...]
27 B<mr> [options] action [params ...]
31 B<mr> is a Multiple Repository management tool. It
32 can checkout, update, or perform other actions on
33 a set of repositories as if they were one combined respository. It
34 supports any combination of subversion, git, cvs, and bzr repositories,
35 and support for other revision control systems can easily be added.
37 B<mr> cds into and operates on all registered repositories at or below your
38 working directory. Or, if you are in a subdirectory of a repository that
39 contains no other registered repositories, it will stay in that directory,
40 and work on only that repository,
42 These predefined commands should be fairly familiar to users of any revision
47 =item checkout (or co)
49 Checks out any repositories that are not already checked out.
53 Updates each repository from its configured remote repository.
55 If a repository isn't checked out yet, it will first check it out.
59 Displays a status report for each repository, showing what
60 uncommitted changes are present in the repository.
64 Commits changes to each repository. (By default, changes are pushed to the
65 remote repository too, when using distributed systems like git.)
67 The optional -m parameter allows specifying a commit message.
71 Show a diff of uncommitted changes.
79 These commands are also available:
85 List the repositories that mr will act on.
89 Register an existing repository in the mrconfig file. By default, the
90 repository in the current directory is registered, or you can specify a
91 directory to register.
93 By default it registers it to the ~/.mrconfig file. To make it write to a
94 different file, use the -c option.
98 Adds, modifies, removes, or prints a value from the mrconfig file. The next
99 parameter is the name of the section the value is in. To add or modify
100 values, use one or more instances of "parameter=value". Use "parameter=" to
101 remove a parameter. Use just "parameter" to get the value of a parameter.
103 For example, to add (or edit) a repository in src/foo:
105 mr config src/foo checkout="svn co svn://example.com/foo/trunk foo"
107 To show the command that mr uses to update the repository in src/foo:
109 mr config src/foo update
117 Actions can be abbreviated to any unambiguous subsctring, so
118 "mr st" is equivilant to "mr status", and "mr up" is equivilant to "mr
121 Additional parameters can be passed to most commands, and are passed on
122 unchanged to the underlying revision control system. This is mostly useful
123 if the repositories mr will act on all use the same revision control
132 Specifies the topmost directory that B<mr> should work in. The default is
133 the current working directory.
137 Use the specified mrconfig file, instead of looking for one in your home
146 Expand the statistics line displayed at the end to include information
147 about exactly which repositories failed and were skipped, if any.
153 B<mr> is configured by .mrconfig files. It starts by reading the .mrconfig
154 file in your home directory, and this can in turn chain load .mrconfig files
157 Here is an example .mrconfig file:
160 checkout = svn co svn://svn.example.com/src/trunk src
164 checkout = git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git &&
166 git checkout -b mybranch origin/master
168 The .mrconfig file uses a variant of the INI file format. Lines starting with
169 "#" are comments. Values can be continued to the following line by
170 indenting the line with whitespace.
172 The "DEFAULT" section allows setting default values for the sections that
175 The "ALIAS" section allows adding aliases for actions. Each parameter
176 is an alias, and its value is the action to use.
178 All other sections add repositories. The section header specifies the
179 directory where the repository is located. This is relative to the directory
180 that contains the mrconfig file, but you can also choose to use absolute
183 Within a section, each parameter defines a shell command to run to handle a
184 given action. mr contains default handlers for the "update", "status", and
185 "commit" actions, so normally you only need to specify what to do for
188 Note that these shell commands are run in a "set -e" shell
189 environment, where any additional parameters you pass are available in
190 "$@". The "checkout" command is run in the parent of the repository
191 directory, since the repository isn't checked out yet. All other commands
192 are run inside the repository, though not necessarily at the top of it.
193 The "MR_REPO" environment variable is set to the path to the top of the
194 repository, and "MR_CONFIG" is set to the topmost .mrconfig file used.
196 A few parameters have special meanings:
202 If the "skip" parameter is set and its command returns nonzero, then B<mr>
203 will skip acting on that repository. The command is passed the action
206 Here are two examples. The first skips the repo unless
207 mr is run by joey. The second uses the hours_since function
208 (included in mr's built-in library) to skip updating the repo unless it's
209 been at least 12 hours since the last update.
211 skip = test $(whoami) != joey
212 skip = [ "$1" = update ] && [ $(hours_since "$1") -lt 12 ]
216 If the "chain" parameter is set and its command returns nonzero, then B<mr>
217 will try to load a .mrconfig file from the root of the repository. (You
218 should avoid chaining from repositories with untrusted committers.)
222 If the "deleted" parameter is set and its command returns nonzero, then
223 B<mr> will treat the repository as deleted. It won't ever actually delete
224 the repository, but it will warn if it sees the repository's directory.
225 This is useful when one mrconfig file is shared amoung multiple machines,
226 to keep track of and remember to delete old repositories.
230 The "lib" parameter can specify some shell code that will be run before each
231 command, this can be a useful way to define shell functions for other commands
