DESCRIPTION

      This configurable perl script builds an fvwm menu definition for headlines of popular news web sites: FreshMeat,
      Slashdot, LinuxToday, DaemonNews, GNOME-News, KDE-News, RootPrompt, LinuxFr, ThinkGeek, CNN, BBC and more.
 
      It is possible to specify a customized menu item format, change a command (usually launching a browser) and add
      menu icons (there is a support for the wm-icons package).

OPTIONS

      --help
          show the help and exit
 
      --version
          show the version and exit
 
      --info [site]
          if site name is given print the site specific info, otherwise print all site names
 
      --site site
          defile a web site, headlines of which to show, this option also can be used together with --help to get new
          defaults.  Default site: freshmeat.
 
      --name name
          define menu name (default is "MenuHeadlinesFreshmeat")
 
      --title title
          define menu title (default is "Freshmeat Headlines").
 
      --item label-format
      --exec command-format
          define format for menu item or command (what is shown and what is executed when the item is chosen).  Default
          label is '%h\t%[(%Y-%m-%d %H:%M)]'.  TAB can be specified as '\t', but in .fvwm2rc you should specify a dou-
          ble backslash or a real TAB.
 
          Format specifiers for a headline format:
 
            %h - headline
            %u - url
            %d - date in the native format (that site backend supplied)
            %[strftime-argument-string] - date/time, see strftime(3)
              the date/time is represented accourding to the local time;
              date and/or time fields that can't be guessed are stripped
              Example: %[|%d %B %Y| %H:%M %S]
                If site supplied only date - this becomes %[|%d %B %Y|],
                if site supplied no date - this becomes an empty string.
            %{name} - site specific named value, like %{comments}
            %(text) - arbitrary text, good for escaping or aligning
 
          These specifiers can receive an optional integer size, positive for right adjusted string or negative for
          left adjusted, example: %8x; and optional *num or *-num, which means to leave only the first or last (if
          minus) num of chars, the num must be greater than 3, since the striped part is replaced with "...", example:
          %*30x. Both can be combined: %-10*-20x, this instructs to get only the 20 last characters, but if the length
          is less then 10 - to fill with up to 10 spaces on the right.
 
      --command command-format
          like --exec above, but enables to specify any fvwm command, for example, "Function FuncFvwmShowURL '%u'" not
          only Exec.
 
          In fact, --exec="mozilla '%u'" is equivalent to --command="Exec mozilla '%u'"
 
      --icon-title icon
      --icon-item icon
      --icon-home icon
      --icon-error icon
          define menu icon for title, regular item, frontpage item and error item respectively. Default is no menu
          icons (equivalent to an empty icon argument).
 
      --wm-icons
          define icon names suitable for use with wm-icons package.  Currently this is equivalent to: --icon-title 
          --icon-item menu/information.xpm --icon-home menu/home.xpm --icon-error menu/choice-no.xpm.
 
      --frontpage [where]
          add the site frontpage item to the menu.  Optional value can be used to specify where this item will be
          placed in the menu - 'top' or 't', 'bottom' or 'b'.
 
      --proxy host[:port]
          define a proxy to use.  Example: --proxy proxy.inter.net:3128
 
      --file [file]
          write the menu output to specified file. If no filename is given with this option (or empty filename), the
          default filename WORK_HOME/SITE.menu is used. Without this option or with '-' filename, the menu output is
          written to standard output.
 
      --fake [file]
          don't connect to the host using HTTP protocol, instead, read from WORK_HOME/SITE.in file. The following reads
          input from freshmeat.in (downloaded http://freshmeat.net/backend/recentnews.txt) and saves output to seg-
          fault.menu (both files are in WORK_HOME):
            fvwm-menu-headlines --site freshmeat --fake --file
 
      --timeout seconds
          limit a line reading from a socket to this timeout, the default timeout is 20 seconds.
 
      WORK_HOME of this script is ~/.fvwm/.fvwm-menu-headlines.  It is created if needed.
 
      Option parameters can be specified either using '=' or in the next argument.  Short options are ok if not ambigu-
      ous: "-h", "-t"; but be careful with short options, what is now unambiguous, can become ambiguous in the next
      versions.

USAGE

      1. One of the ways to use this script is to define a crontab entry to run the script every hour or so for every
      monitored site:
 
        0,30 * * * * fvwm-menu-headlines --file --site freshmeat
        1,31 * * * * fvwm-menu-headlines --file --site linuxtoday
        2,32 * * * * fvwm-menu-headlines --file --site slashdot
 
      Then add these lines to your fvwm configuration file:
 
        DestroyFunc FuncFvwmMenuHeadlines
        AddToFunc   FuncFvwmMenuHeadlines
        + I Read "$HOME/.fvwm/.fvwm-menu-headlines/$0.menu"
 
        DestroyMenu MenuHeadlines
        AddToMenu   MenuHeadlines "Headlines" Title
        + MissingSubmenuFunction FuncFvwmMenuHeadlines
        + "FreshMeat"  Popup freshmeat
        + "LinuxToday" Popup linuxtoday
        + "Slashdot"   Popup slashdot
 
      2. Another way to use this script (only if you have fast network/proxy) is to run it every time you want to open
      your Headlines submenus.  (Note, the submenu that is once created is not reloaded, use "Reset all".)
 
      In this case your fvwm configuration lines could be:
 
        DestroyFunc FuncFvwmMenuHeadlines
        AddToFunc   FuncFvwmMenuHeadlines
        + I PipeRead "fvwm-menu-headlines --site $0"
        #+ I Schedule 900000 DestroyMenu $0  # reset generated menu in 15 minutes
 
        DestroyMenu MenuHeadlines
        AddToMenu   MenuHeadlines "Headlines" Title
        + MissingSubmenuFunction FuncFvwmMenuHeadlines
        + "FreshMeat"  Popup freshmeat
        + "Slashdot"   Popup slashdot
        + "LinuxToday" Popup linuxtoday
        + "GNOME News" Popup gnome-news
        + "KDE News"   Popup kde-news
        + "" Nop
        + "Reset all"  FuncResetHeadlines
 
        DestroyFunc FuncResetHeadlines
        AddToFunc   FuncResetHeadlines
        + I DestroyMenu freshmeat
        + I DestroyMenu linuxtoday
        + I DestroyMenu slashdot
        + I DestroyMenu gnome-news
        + I DestroyMenu kde-news
 
      And finally, add "Popup MenuHeadlines" somewhere.
 
      3. Here is a usual usage. Use FvwmConsole or FvwmCommand to run fvwm commands from a shell script. Every time you
      want headlines from some site, execute (give any additional options if you want):
 
        PipeRead "fvwm-menu-headlines --site newsforge --name MenuHeadlinesNewsForge"
        # this may take several seconds, you may use: BusyCursor Read true
        Popup MenuHeadlinesNewsForge

HOW TO ADD SITE HEADLINES

      It is possible to add user defined site headlines without touching the script itself. Put your perl extensions to
      the file WORK_HOME/extension.pl.  For each site add something similar to:
 
        $siteInfo->{'myslashdot'} = {
          'name' => "MySlashdot",
          'host' => "myslashdot.org",
          'path' => "/myslashdot.xml",
          'func' => \&processMySlashdot,
          # the following string is only used in --info
          'flds' => 'time, title, department, topic, author, url',
        };
 
        sub processMySlashdot () {
          return processXml(
            'story',
            # mandatory 'h', 'u' and 'd' aliases or undef
            { 'h' => 'title', 'u' => 'url', 'd' => 'time' },
            sub ($) {  # convert 'd' string to (y, m, d, H, M, S)
              $_[0] =~ /(\d+)-(\d+)-(\d+) (\d+):(\d+):(\d+)/;
              ($1, ($2 || 0) - 1, $3, $4, $5, $6);
            }, +0,  # timezone offset; already in UTC
          );
        }
 
        1;

COPYING

      The script is distributed by the same terms as fvwm itself.  See GNU General Public License for details.

BUGS

      I try to keep all supported site info up to date, but sites often go down, change their backend formats, change
      their httpd responses, just stop to post news and so on; the script in the latest cvs may be more up to date.
 
      The headline times may be off by one hour or more, since the time is displayed for your local time zone, and the
      time zone of the original time in the site backend output is often guessed (sometimes incorrectly); similarly it
      is guessed whether to apply the daylight saving correction.
 
      Report bugs to fvwm-bug@fvwm.org.
