Description: vm 2.0.12
        =========
        
        Updates versions across multiple files.
        
        Install
        -------
        
        .. code:: sh
        
            pip install vm
        
        Usage
        -----
        
        You need a ``versions.json``, or a ``versions.yml`` where you can
        specify for what you're tracking the versions, and what files to be
        updated using glob patterns:
        
        .. code:: yaml
        
            germanium:
              version: 1.10.3
              files:
                README.*: "^(germanium )(.*?)$"
                setup.py: "version='**VERSION**',"
                doc/usage/index.adoc: "^(= Germanium v)(.*?)$"
                germanium/version.py: "current = \"**VERSION**\""
        
        Help:
        
        .. code:: text
        
            usage: vm [-h] [--display NAME] [--all] [--set NAME=VAL [NAME=VAL ...]]
                      [--load FILE] [-t]
        
            Versions processor
        
            optional arguments:
              -h, --help            show this help message and exit
              --display NAME, -d NAME
                                    Display the version of a single tracked version.
              --all, -a, --list     Display all the tracked versions and their values.
              --set NAME=VAL [NAME=VAL ...], -s NAME=VAL [NAME=VAL ...]
                                    Set values overriding what's in the yml files.
              --load FILE, -l FILE  Override versions from the given yml file.
              -t, --tag-name, --tag
                                    Get the current name to use in general tags.
        
        Specifying Versions
        -------------------
        
        The version value will be expanded using the shell if it contains a '$'
        or a '\`', so you can have a version such as:
        
        .. code:: json
        
            "description": {
              "version": "Build at $(date) on $(uname -n)"
            }
        
        Versions can also refer to other version files, and extract properties
        from there, using the ``parent:`` notation in the version:
        
        .. code:: json
        
            "germaniumdrivers": {
              "version": "parent:../germanium/@germaniumdrivers"
            }
        
        The path will point to the ``versions.json/yml`` file, or to the folder
        that contains the ``versions.json/yml`` file, and after that fill will
        be read and interpreted the ``germaniumdrivers`` version will be used.
        
        Versions can be also manually overriden from the command line, using the
        ``--set`` or ``-s`` flag, for example:
        
        .. code:: sh
        
            vm -s germanium=2.0.8
        
        This will ignore the value specified in the versions.yml file, and use
        the specified one.
        
        File Matchers
        -------------
        
        There are currently only four file matchers:
        
        RegExp File Matcher
        ~~~~~~~~~~~~~~~~~~~
        
        It is a RegExp that has two or three groups, and it will have the second
        group replaced to the matched version.
        
        **VERSION** File Matcher
        ~~~~~~~~~~~~~~~~~~~~~~~~
        
        This will construct a RegExp that will match exactly the given text,
        with the ``**VERSION**`` being the second group.
        
        So having a matcher such as:
        
        .. code:: json
        
            "files": {
                "README": "This installs version **VERSION** of the product."
            }
        
        is equivalent with:
        
        .. code:: yaml
        
            files:
                README: "(This installs version )(.+?)( of the product\\.)"
        
        If the ``**``\ s are replaced with ``^^`` at the beginning, or ``$$`` at
        the end, they will act as RegExp anchors, equivalent to ``^`` and ``$``.
        In case in the expression there is content before the ``^^``, or after
        the ``$$``, the content is ignored.
        
        maven: File Matcher
        ~~~~~~~~~~~~~~~~~~~
        
        This will construct a RegExp that will match:
        
        .. code:: text
        
            `(<groupId>${m[1]}</groupId>\\s*` +
            `<artifactId>${m[2]}</artifactId>\\s*` +
            `<version>)(.*?)(</version>)`;
        
        In order to specify the matcher, just use:
        
        .. code:: yaml
        
            germanium:
              version: 2.0.0
              files:
                pom.xml: maven:com.germaniumhq:germanium
        
        Matcher Constraints
        -------------------
        
        In order to make sure that the expressions are not replacing in too many
        places, constraints can be added to limit, or extend the matches.
        
        Matcher constraints are always active, and in case no constraint is
        specified then the maximum replacement count is set to 1.
        
        Match Count
        ~~~~~~~~~~~
        
        .. code:: json
        
            "product" : {
              "version": "1.0",
              "files": {
                "README.md": {
                  "match": "^(= Germanium v)(.*?)$",
                  "count": 1
                }
              }
            }
        
        The count can be also ``0`` for no matches, or negative to indicate any
        number of matches is allowed.
        
        Multiple Matchers
        -----------------
        
        In a single file, we can have multiple matchers as well, for example:
        
        .. code:: json
        
            "product" : {
              "version": "1.0",
              "files": {
                "README.md": [
                  "^(= Germanium v)(.*?)$",
                  "(Germanium )(\\d+\\.\\d+)()"
                ]
              }
            }
        
        For each matcher that is added, if there is no match count specified,
        it's assumed that it will only match once in the file.
        
        Of course, constraints can be applied for both the full set of matchers:
        
        .. code:: json
        
            "product" : {
              "version": "1.0",
              "files": {
                "README.md": {
                  "match": [
                    "^(= Germanium v)(.*?)$",
                    "(Germanium )(\\d+\\.\\d+)()"
                  ],
                  "count": 3
                }
              }
            }
        
        or even individual expressions:
        
        .. code:: json
        
            "product" : {
              "version": "1.0",
              "files": {
                "README.md": {
                  "match": [
                    "^(= Germanium v)(.*?)$",
                    {
                      "match": "(Germanium )(\\d+\\.\\d+)()",
                      "count": 2
                    }
                  ],
                  "count": 3
                }
              }
            }
        
        Notes
        -----
        
        1. Files are actually ``glob`` patterns, so you can match ``**/*.js``
           for example.
        2. The configuration files can be yml.
        3. ``vm`` will output the following error codes: 0 when no files are
           changed, 0 when files are changed successfuly, or a non zero error
           code in case of error.
