NAME

       pdmenurc - menu definitions file for pdmenu

SYNOPSIS

       /etc/pdmenurc

       ~/.pdmenurc

DESCRIPTION

       The pdmenurc file defines menus for pdmenu(1) to display. Each menu consists of one or more menu entries.
       The first menu to appear in the file is displayed by pdmenu(1) when it  starts  up,  and  can  have  menu
       entries that call up submenus.

EXAMPLES

       Here is a sample pdmenurc file:

        #Set a pleasing color scheme.
        color:desktop:blue:blue
        color:title:blue:white
        color:base:blue:white

        #this is a comment
        menu:main:Main Menu:Things to do at foobar
             show:_Games..::games
             exec:_Mail::pine
             exec:_News::slrn -C
             exec:_WWW::lynx
             exec:_Irc::irc
             exec:_Directory _Listing:display:ls -l
             exec:_Who's online?:truncate:w
             exec:_Finger:edit,truncate:finger ~finger who?:~
             nop
             exit:E_xit

        menu:games:Games:Some text-based games
            exec:_Tetris for Terminals::/usr/games/tt
            exec:_Adventure:pause:/usr/games/adventure
            exec:_Zork:pause:/usr/games/zork
            nop
            exit:_Back to main menu..

       This will display a menu, with a submenu for games.

FORMAT

       pdmenu(1)  doesn't  care  how the pdmenurc is indented; all whitespace is ignored.  However, each command
       must be on its own line. The commands are grouped into two classes: those that appear only in menus,  and
       those that can appear anywhere in the file.

   COMMANDS THAT MAY BE USED ANYWHERE
       These  commands  may  appear  in a menu, or outside of a menu. They take effect as soon as pdmenu(1) sees
       them.

       menu   This starts a menu. All items between this menu command and the next will comprise one menu. If  a
              menu  with  the same id has already been defined earlier, then all items between this menu command
              and the next will be added to the menu.  The syntax is:

              menu:menuid:title[:helptext]

              menuid The id of the menu (each menu must have a unique id).

              title  The title of the menu.

              helptext
                     Text to be displayed at the bottom of the screen when the menu is active.

       title  This overrides the default title at the top of the screen. The syntax is:

              title:text

       color  This changes the color of a part of the display.  Later  color  commands  override  earlier  color
              commands that would affect the same part of the display. The syntax is:

              color:screenpart:foreground[:background]

              screenpart
                     The  area of the screen which takes on the selected color scheme.  Areas of the screen that
                     can be set are:

                     desktop
                            The space over which the menus appear.

                     title  The line at the top of the screen.

                     base   The line at the bottom of the screen.

                     menu   The normal color of text in a menu.

                     selbar The selection bar in the menu, when over normal text.

                     shadow The shadow of a window

                     menuhot
                            The color of text in a menu that is a hotkey.

                     selbarhot
                            The color of a hotkey when the selection bar is over it.

                     unselmenu
                            The color of a menu window that is not currently active.

              foreground
                     The color to use in the foreground. Valid colors are:
                      black           gray
                      red             brightred
                      green           brightgreen
                      brown           yellow
                      blue            brightblue
                      magenta         brightmagenta
                      cyan            brightcyan
                      lightgray       white

              background
                     The color to use in the background.  On most terminals, the background color  can  only  be
                     one of the colors listed in the first column above.

       read   This  causes  another  menu  definitions file to be read in and replace the read command.  This is
              quite similar to #include in a c program. The syntax is:

              read:rcfile

              Note that no checking is done to prevent recursive  read  commands,  and  that  such  a  recursive
              command can crash pdmenu.

       preproc
              This  runs  a  command,  and uses its output as a pdmenurc file, which is read in and replaces the
              preproc command. Typically a preprocessor such as m4 or cpp will be used. The syntax is:

              preproc:command [args]

              Note that no checking is done to prevent recursive preproc commands, and  that  such  a  recursive
              command can crash pdmenu.

   COMMANDS THAT MUST APPEAR INSIDE MENUS
       These commands must always appear within a menu. They are only executed if the user selects them from the
       menu.

       show   This displays a submenu. The syntax is:

              show:desc:flags:menuid

              menuid The id of the menu to show, corresponding to the menuid given in the menu's definition.

              desc   The description of the submenu to appear in the parent window.

                     To place a hotkey in the description, put a '_' before the character you want to become the
                     hotkey.  It  is  a  good  idea  to  differentiate  submenus from commands in a menu by, for
                     example, appending ".." to their descriptions.

              flags  Currently ignored.

       nop    This does nothing but place a blank line in the menu. Nop commands may not  appear  as  the  first
              command in a menu.  Syntax:

              nop[:text]

              text   If  this is present, it will appear in the menu where the nop is. Otherwise, the nop in the
                     menu will be a blank line.

       helptext
              This changes the helptext of the currently displayed menu. The syntax is:

              helptext:desc:flags:help text

              desc   The text to appear on the menu.

              flags  Currently the only available flag is "command", which makes the help text be read in from a
                     command  in the help text field, instead of using the literal value of the field. The first
                     line the command outputs becomes the new help text.

       exit   If only one menu is on the screen when this is selected, then pdmenu(1) will quit. Otherwise, this
              will  take  the  user back to the parent menu of the menu they are currently in. Selecting an exit
              command in a menu is equivalent to pressing 'q', unless you have ran pdmenu(1) with the -q switch.
              The syntax is:

              exit:desc

              desc   The description of the menu item.

                     To place a hotkey in the description, put a '_' before the character you want to become the
                     hotkey.

       group  This creates a menu entry that can run multiple  commands  at  the  same  time.  After  the  group
              command,  list  the  commands  that make up the group.  Close the group with the endgroup command.
              When the group is selected from the menu, each command in the group will be  run,  in  turn.  Note
              that  if  a  group  caintains  an  exit command, processing will stop there even if there are more
              commands in the group. Group commands may not be nested. The syntax is:

              group:desc

              desc   The description of the menu item.

                     To place a hotkey in the description, put a '_' before the character you want to become the
                     hotkey.

       endgroup
              This  closes  a  group  command.  Every command between the opening group command and the endgroup
              comprises a group of commands.

       exec   This runs a command. The syntax is:

              exec:desc:flags:command

              command
                     The actual command to run when this item is selected.

                     Normally, pdmenu(1) passes the command to system(3) for exacution.  However, if  the  first
                     token  of  the  command is "exec", then the command is executed directly with the execvp(3)
                     system call.  As such, the pdmenu(1) process is wholly replaced by the command.

              desc   The description of the command that appears in the menu.

                     To place a hotkey in the description, put a '_' before the character you want to become the
                     hotkey.

              flags  How  to run this command, and what to do with its output. Any number of the following flags
                     can be specified, in any order, separated by commas.  (for example, "display,edit")

                     Some of the flags conflict with each over, for example, 'display' and 'pause'  cannot  both
                     be  used at the same time. If conflicting flags are specified, Pdmenu will just pick one of
                     them and use it.

                     Note that to maintain backward compatability with old versions of Pdmenu, the flags can  be
                     formatted differently: as a sequence of characters, each character a flag and corrisponding
                     to the first character of the long  flag  name,  and  nothing  separating  the  characters.
                     However, this format is obsolete and hard to understand, and should no longer be used.

                     noclear
                            By  default  the  screen  is  cleared  and  the  terminal  is reset to normal before
                            pdmenu(1) runs a command from the menu, and after the command exits, the  screen  is
                            redrawn.  If  this  flag is set, the screen is not cleared or redrawn. Use it if you
                            have a command on the  menu  that  does  not  produce  any  output  to  the  screen.
                            (Conflicts with: 'pause')

                     pause  Pause  after  the  command  exits.  Use  this  if  you need to see the output of the
                            command.  (Conflicts  with:  'noclear',  'display',  'truncate',   'makemenu',   and
                            'setenv')

                     display
                            Display the output of the command in a window. If this flag is set, the 'pause' flag
                            is disabled, and the 'noclear' flag is automatically set.  If  the  command  outputs
                            lines  that  are  too long, they will be wrapped inside the window. (Conflicts with:
                            'pause', 'truncate', 'makemenu', 'setenv')

                     truncate
                            Like 'display', except the output of the command is truncated to fit in the  window,
                            not wrapped.  (Conflicts with: 'pause', 'display', 'mmakemenu', 'setenv')

                     edit   Edit the command interactively.

                            When  this  flag is set, the command to be run is scanned for any tags of the format
                            ~title:default~. For each that is found, a text entry window is displayed, with  the
                            title  equal  to  the contents of the title field, and the default text equal to the
                            contents of the default field.

                            To use the '~' or ':' characters in the command without having them  interpreted  as
                            tag delimiters, escape them with a '\' character.  (Ie, '\~' and '\:')

                            Security  warning!  Any  exec  command  that uses the 'edit' flag will be a security
                            hole. The user need only to enter text with a  ';'  in  it,  and  they  can  run  an
                            arbitrary command after the semicolon!

                            There  is  no  fix  for  this  security  problem  at  this time. If the user running
                            pdmenu(1) is not a trusted user (if they are a guest user, say), do not  allow  them
                            access to any exec commands that have the 'edit' flag set.

                     makemenu
                            This  flag  lets  you generate menus on the fly as pdmenu(1) is running. It runs the
                            command, then processes the output of the command as if it were a pdmenurc file.

                            Here is a sample use of this flag. It creates a menu of people who  are  logged  on,
                            and  lets  you talk to one of them. Notice the use of remove to clear the menu after
                            we use it.

                              group:_Talk
                                exec::makemenu: \
                                  echo "menu:talk:Talk"; \
                                  for u in `users`; do \
                                    echo "exec:$u::talk $u"; \
                                  done
                                show:::talk
                                remove:::talk
                              endgroup

                            (Conflicts with: 'display', 'truncate', 'pause', 'display', 'setenv')

                     setenv Set an environment variable.

                            This flag causes pdmenu(1) to set a variable in its own environment.  pdmenu(1) runs
                            the exec command, and looks at the command's output. The first line should be in the
                            format
                                   VAR=value
                            Where VAR is the environment variable to set, and value is the  new  value  for  the
                            variable.

                            For  example,  use  "echo  PWD=/tmp"  to  set the current working directory to /tmp.
                            (Conflicts with: 'makemenu', 'display', 'truncate', and 'pause')

       remove This removes a menu from Pdmenu's list of menus. You should never attempt to remove a menu that is
              currently being displayed on screen. The syntax is:

              remove:desc:flags:menuid

              desc   The description of the command that appears in the menu.

                     To place a hotkey in the description, put a '_' before the character you want to become the
                     hotkey.

              flags  Currently ignored.

              menuid The id of the menu to remove. If the menu wih  id  menuid  does  not  exist,  no  error  is
                     reported.

              This command is typically used after creating and using a new menu via the
               'makemenu' flag to exec, to remove a menu that is no longer needed.  For example, if you have the
              followng pdmenurc:

               menu:main:Main Menu
                 group:_Test
                   exec::makemenu: \
                     echo menu:sample:Dir; \
                     echo exec:_Directory:pause:ls
                   show:::sample
                 endgroup

              Each time the user selects "Test" from the Main Menu, the menu that appears has another  Directory
              command  on it. If you don't want this to happen, and you want only one Directory command to be on
              the menu, add a command to remove the menu after it is used, like this:

               menu:main:Main Menu
                 group:_Test
                   exec::makemenu: \
                     echo menu:sample:Dir; \
                     echo exec:_Directory:pause:ls
                   show:::sample
                   remove:::sample
                 endgroup

NOTES

       If a line ends with '\', pdmenu(1) will read in the next line as part of the same logical line.

       If you want the ':' character to appear in a field, you may escape out the ':' character by  placing  '\'
       before it. You don't need to do this if the field is the last field in a line.

FILES

       /etc/pdmenurc
