DESCRIPTION

       mr is a tool to manage all your version control repos. It can checkout, update, or perform
       other actions on a set of repositories as if they were one combined repository. It
       supports any combination of subversion, git, cvs, mercurial, bzr, darcs, fossil and
       veracity repositories, and support for other version control systems can easily be added.

       mr cds into and operates on all registered repositories at or below your working
       directory. Or, if you are in a subdirectory of a repository that contains no other
       registered repositories, it will stay in that directory, and work on only that repository,

       mr is configured by .mrconfig files, which list the repositories. It starts by reading the
       .mrconfig file in your home directory, and this can in turn chain load .mrconfig files
       from repositories. It also automatically looks for a .mrconfig file in the current
       directory, or in one of its parent directories.

       These predefined commands should be fairly familiar to users of any version control
       system:

       checkout (or co)
           Checks out any repositories that are not already checked out.

       update
           Updates each repository from its configured remote repository.

           If a repository isn't checked out yet, it will first check it out.

       status
           Displays a status report for each repository, showing what uncommitted changes are
           present in the repository. For distributed version control systems, also shows
           unpushed local branches.

       commit (or ci)
           Commits changes to each repository. (By default, changes are pushed to the remote
           repository too, when using distributed systems like git. If you don't like this
           default, you can change it in your .mrconfig, or use record instead.)

           The optional -m parameter allows specifying a commit message.

       record
           Records changes to the local repository, but does not push them to the remote
           repository. Only supported for distributed version control systems.

           The optional -m parameter allows specifying a commit message.

       fetch
           Fetches from each repository's remote repository, but does not update the working
           copy. Only supported for some distributed version control systems.

       push
           Pushes committed local changes to the remote repository. A no-op for centralized
           version control systems.

       diff
           Show a diff of uncommitted changes.

       log Show the commit log.

       grep pattern
           Searches for a pattern in each repository using the grep subcommand. Uses ack-grep on
           VCS that do not have their own.

       run command [param ...]
           Runs the specified command in each repository.

       These commands are also available:

       bootstrap url [directory]
           Causes mr to download the url, and use it as a .mrconfig file to checkout the
           repositories listed in it, into the specified directory.

           To use scp to download, the url may have the form ssh://[user@]host:file

           The directory will be created if it does not exist. If no directory is specified, the
           current directory will be used.

           If the .mrconfig file includes a repository named ".", that is checked out into the
           top of the specified directory.

       list (or ls)
           List the repositories that mr will act on.

       register
           Register an existing repository in a mrconfig file. By default, the repository in the
           current directory is registered, or you can specify a directory to register.

           The mrconfig file that is modified is chosen by either the -c option, or by looking
           for the closest known one at or in a parent of the current directory.

       config
           Adds, modifies, removes, or prints a value from a mrconfig file. The next parameter is
           the name of the section the value is in. To add or modify values, use one or more
           instances of "parameter=value". Use "parameter=" to remove a parameter. Use just
           "parameter" to get the value of a parameter.

           For example, to add (or edit) a repository in src/foo:

             mr config src/foo checkout="svn co svn://example.com/foo/trunk foo"

           To show the command that mr uses to update the repository in src/foo:

             mr config src/foo update

           To see the built-in library of shell functions contained in mr:

             mr config DEFAULT lib

           The mrconfig file that is used is chosen by either the -c option, or by looking for
           the closest known one at or in a parent of the current directory.

       offline
           Advises mr that it is in offline mode. Any commands that fail in offline mode will be
           remembered, and retried when mr is told it's online.

       online
           Advices mr that it is in online mode again. Commands that failed while in offline mode
           will be re-run.

       remember
           Remember a command, to be run later when mr re-enters online mode. This implicitly
           puts mr into offline mode. The command can be any regular mr command. This is useful
           when you know that a command will fail due to being offline, and so don't want to run
           it right now at all, but just remember to run it when you go back online.

       help
           Displays this help.

       Actions can be abbreviated to any unambiguous substring, so "mr st" is equivalent to "mr
       status", and "mr up" is equivalent to "mr update"

       Additional parameters can be passed to most commands, and are passed on unchanged to the
       underlying version control system. This is mostly useful if the repositories mr will act
       on all use the same version control system.

OPTIONS

       -d directory
       --directory directory
           Specifies the topmost directory that mr should work in. The default is the current
           working directory.

       -c mrconfig
       --config mrconfig
           Use the specified mrconfig file. The default is to use both ~/.mrconfig as well as
           look for a .mrconfig file in the current directory, or in one of its parent
           directories.

       -f
       --force
           Force mr to act on repositories that would normally be skipped due to their
           configuration.

       -v
       --verbose
           Be verbose.

       -q
       --quiet
           Be quiet. This suppresses mr's usual output, as well as any output from commands that
           are run (including stderr output). If a command fails, the output will be shown.

       -k
       --insecure
           Accept untrusted SSL certificates when bootstrapping.

       -s
       --stats
           Expand the statistics line displayed at the end to include information about exactly
           which repositories failed and were skipped, if any.

       -i
       --interactive
           Interactive mode. If a repository fails to be processed, a subshell will be started
           which you can use to resolve or investigate the problem. Exit the subshell to continue
           the mr run.

       -n [number]
       --no-recurse [number]
           If no number if specified, just operate on the repository for the current directory,
           do not recurse into deeper repositories.

           If a number is specified, will recurse into repositories at most that many
           subdirectories deep. For example, with -n 2 it would recurse into ./src/foo, but not
           ./src/packages/bar.

       -j [number]
       --jobs [number]
           Run the specified number of jobs in parallel, or an unlimited number of jobs with no
           number specified. This can greatly speed up operations such as updates.  It is not
           recommended for interactive operations.

           Note that running more than 10 jobs at a time is likely to run afoul of ssh connection
           limits. Running between 3 and 5 jobs at a time will yield a good speedup in updates
           without loading the machine too much.

       -t
       --trust-all
           Trust all mrconfig files even if they are not listed in ~/.mrtrust.  Use with caution.

       -p
       --path
           This obsolete flag is ignored.

MRCONFIG FILES

       Here is an example .mrconfig file:

         [src]
         checkout = svn checkout svn://svn.example.com/src/trunk src
         chain = true

         [src/linux-2.6]
         checkout = git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git &&
               cd linux-2.6 &&
               git checkout -b mybranch origin/master

       The .mrconfig file uses a variant of the INI file format. Lines starting with "#" are
       comments. Values can be continued to the following line by indenting the line with
       whitespace.

       The "DEFAULT" section allows setting default values for the sections that come after it.

       The "ALIAS" section allows adding aliases for actions. Each parameter is an alias, and its
       value is the action to use.

       All other sections add repositories. The section header specifies the directory where the
       repository is located. This is relative to the directory that contains the mrconfig file,
       but you can also choose to use absolute paths. (Note that you can use environment
       variables in section names; they will be passed through the shell for expansion. For
       example, "[$HOSTNAME]", or "[${HOSTNAME}foo]").

       Within a section, each parameter defines a shell command to run to handle a given action.
       mr contains default handlers for "update", "status", "commit", and other standard actions.

       Normally you only need to specify what to do for "checkout". Here you specify the command
       to run in order to create a checkout of the repository.  The command will be run in the
       parent directory, and must create the repository's directory. So use "git clone", "svn
       checkout", "bzr branch" or "bzr checkout" (for a bound branch), etc.

       Note that these shell commands are run in a "set -e" shell environment, where any
       additional parameters you pass are available in $@. All commands other than "checkout" are
       run inside the repository, though not necessarily at the top of it.

       The "MR_REPO" environment variable is set to the path to the top of the repository. (For
       the "register" action, "MR_REPO" is instead set to the basename of the directory that
       should be created when checking the repository out.)

       The "MR_CONFIG" environment variable is set to the .mrconfig file that defines the repo
       being acted on, or, if the repo is not yet in a config file, the .mrconfig file that
       should be modified to register the repo.

       The "MR_ACTION" environment variable is set to the command being run (update, checkout,
       etc).

       A few parameters have special meanings:

       skip
           If the "skip" parameter is set and its command returns true, then mr will skip acting
           on that repository. The command is passed the action name in $1.

           Here are two examples. The first skips the repo unless mr is run by joey. The second
           uses the hours_since function (included in mr's built-in library) to skip updating the
           repo unless it's been at least 12 hours since the last update.

             [mystuff]
             checkout = ...
             skip = test `whoami` != joey

             [linux]
             checkout = ...
             skip = [ "$1" = update ] && ! hours_since "$1" 12

           Another way to use skip is for a lazy checkout. This makes mr skip operating on a repo
           unless it already exists. To enable the repo, you have to explicitly check it out
           (using "mr --force -d foo checkout").

             [foo]
             checkout = ...
             skip = lazy

       order
           The "order" parameter can be used to override the default ordering of repositories.
           The default order value is 10. Use smaller values to make repositories be processed
           earlier, and larger values to make repositories be processed later.

           Note that if a repository is located in a subdirectory of another repository, ordering
           it to be processed earlier is not recommended.

       chain
           If the "chain" parameter is set and its command returns true, then mr will try to load
           a .mrconfig file from the root of the repository.

       include
           If the "include" parameter is set, its command is ran, and should output additional
           mrconfig file content. The content is included as if it were part of the including
           file.

           Unlike all other parameters, this parameter does not need to be placed within a
           section.

           mr ships several libraries that can be included to add support for additional version
           control type things (unison, git-svn, git-fake-bare, git-subtree). To include them
           all, you could use:

             include = cat /usr/share/mr/*

           See the individual files for details.

       deleted
           If the "deleted" parameter is set and its command returns true, then mr will treat the
           repository as deleted. It won't ever actually delete the repository, but it will warn
           if it sees the repository's directory.  This is useful when one mrconfig file is
           shared among multiple machines, to keep track of and remember to delete old
           repositories.

       lib The "lib" parameter can specify some shell code that will be run before each command,
           this can be a useful way to define shell functions for other commands to use.

           Unlike most other parameters, this can be specified multiple times, in which case the
           chunks of shell code are accumulatively concatenated together.

       fixups
           If the "fixups" parameter is set, its command is run whenever a repository is checked
           out, or updated. This provides an easy way to do things like permissions fixups, or
           other tweaks to the repository content, whenever the repository is changed.

       VCS_action
           When looking for a command to run for a given action, mr first looks for a parameter
           with the same name as the action. If that is not found, it looks for a parameter named
           "VCS_action" (substituting in the name of the version control system and the action).

           Internally, mr has settings for "git_update", "svn_update", etc. To change the action
           that is performed for a given version control system, you can override these VCS
           specific actions. To add a new version control system, you can just add VCS specific
           actions for it.

       pre_ and post_
           If a "pre_action" parameter is set, its command is run before mr performs the
           specified action. Similarly, "post_action" parameters are run after mr successfully
           performs the specified action. For example, "pre_commit" is run before committing;
           "post_update" is run after updating.

       _append
           Any parameter can be suffixed with "_append", to add an additional value to the
           existing value of the parameter. In this way, actions can be constructed
           accumulatively.

       VCS_test
           The name of the version control system is itself determined by running each defined
           "VCS_test" action, until one succeeds.

UNTRUSTED MRCONFIG FILES

       Since mrconfig files can contain arbitrary shell commands, they can do anything. This
       flexibility is good, but it also allows a malicious mrconfig file to delete your whole
       home directory. Such a file might be contained inside a repository that your main
       ~/.mrconfig checks out. To avoid worries about evil commands in a mrconfig file, mr
       defaults to reading all mrconfig files other than the main ~/.mrconfig in untrusted mode.
       In untrusted mode, mrconfig files are limited to running only known safe commands (like
       "git clone") in a carefully checked manner.

       To configure mr to trust other mrconfig files, list them in ~/.mrtrust.  One mrconfig file
       should be listed per line. Either the full pathname should be listed, or the pathname can
       start with ~/ to specify a file relative to your home directory.

OFFLINE LOG FILE

       The ~/.mrlog file contains commands that mr has remembered to run later, due to being
       offline. You can delete or edit this file to remove commands, or even to add other
       commands for 'mr online' to run. If the file is present, mr assumes it is in offline mode.

EXTENSIONS

       mr can be extended to support things such as unison and git-svn. Some files providing such
       extensions are available in /usr/share/mr/. See the documentation in the files for details
       about using them.

EXIT STATUS

       mr returns nonzero if a command failed in any of the repositories.
