    *pi_spec.txt*   For Vim version 7.2c.  Last change: 2006 Apr 24

    by Gustavo Niemeyer

    This is a filetype plugin to work with rpm spec files.

    Currently, this Vim plugin allows you to easily update the %changelog
    section in RPM spec files.  It will even create a section for you if it
    doesn't exist yet.  If you've already inserted an entry today, it will
    give you the opportunity to just add a new item in today's entry.  If you
    don't provide a format string (|spec_chglog_format|), it'll ask you an
    email address and build a format string by itself.

    1. How to use it	|spec-how-to-use-it|
    2. Customizing		|spec-customizing|

    ==============================================================================

    1. How to use it				*spec-how-to-use-it*

    The spec_chglog plugin provides a map like the following:

    	:map <buffer> <LocalLeader>c <Plug>SpecChangelog

    It means that you may run the plugin inside a spec file by pressing
    your maplocalleader key (default is '\') plus 'c'.  If you do not have
    |spec_chglog_format| set, the plugin will ask you for an email address
    to use in this edit session.

    Every time you run the plugin, it will check to see if the last entry in the
    changelog has been written today and by you.  If the entry matches, it will
    just insert a new changelog item, otherwise it will create a new changelog
    entry.  If you are running with |spec_chglog_release_info| enabled, it will
    also check if the name, version and release matches.  The plugin is smart
    enough to ask you if it should update the package release, if you have not
    done so.

    Setting a map					*spec-setting-a-map*

    As you should know, you can easily set a map to access any Vim command (or
    anything, for that matter).  If you don't like the default map of
    <LocalLeader>c, you may just set up your own key.  The following line
    shows you how you could do this in your .vimrc file, mapping the plugin to
    the <F5> key:

    	au FileType spec map <buffer> <F5> <Plug>SpecChangelog

    Note: the plugin will respect your desire to change the default mapping
          and won't set it.

    This command will add a map only in the spec file buffers.

    ==============================================================================

    2. Customizing					*spec-customizing*

    The format string				*spec_chglog_format*

    You can easily customize how your spec file entry will look like.  To do
    this just set the variable "spec_chglog_format" in your .vimrc file like
    this:

    	let spec_chglog_format = "%a %b %d %Y My Name <my@email.com>"

    Note that "%a %b %d %Y" is the most used time format.  If you don't provide
    a format string, when you run the SpecChangelog command for the first
    time, it will ask you an email address and build the |spec_chglog_format|
    variable for you.  This way, you will only need to provide your email
    address once.

    To discover which format options you can use, take a look at the strftime()
    function man page.

    Where to insert new items			*spec_chglog_prepend*

    The plugin will usually insert new %changelog entry items (note that it's
    not the entry itself) after the existing ones.  If you set the
    spec_chglog_prepend variable

    	let spec_chglog_prepend = 1

    it will insert new items before the existing ones.

    Inserting release info				*spec_chglog_release_info*

    If you want, the plugin may automatically insert release information
    on each changelog entry.  One advantage of turning this feature on is
    that it may control if the release has been updated after the last
    change in the package or not.  If you have not updated the package
    version or release, it will ask you if it should update the package
    release for you.  To turn this feature on, just insert the following
    code in your .vimrc:

    	let spec_chglog_release_info = 1

    Then, the first item in your changelog entry will be something like:

    	+ name-1.0-1cl

    If you don't like the release updating feature and don't want to answer
    "No" each time it detects an old release, you may disable it with

    	let spec_chglog_never_increase_release = 1

    Good luck!!
