       Zwgc is the main zephyr(1) client.  It is responsible  for
       receiving  selected  zephyr notices on behalf of the user,
       formatting them, and displaying them using one or more  of
       the output devices.

   Selection of Zephyr Notices
       Zwgc subscribes to various notice classes and instances on
       behalf of the user.  Only notices in the subscription list
       will  be  received.   The subscription list is composed of
       the default subscriptions  (stored  on  the  server),  the
       user's  subscriptions  file,  and  any  subscriptions made
       using zctl(1).  The user's subscription file  defaults  to
       $HOME/.zephyr.subs,  or it can be specified with the -sub-
       file option.  If "-"  is  specified  as  the  subscription
       filename,  the  subscriptions  will  be read from standard

       The zctl command is used to  manipulate  and  change  sub-
       scriptions.  See the zctl(1) man page for details.

   Zephyr Description Files
       Zwgc formats its output messages according to the commands
       in its description  file.   The  user's  description  file
       ($HOME/.zwgc.desc  by default, or whatever is specified by
       -f) is read, or the system file is read if the user's does
       not exist.

       Every  time  a  notice  is received, zwgc runs through the
       description file, and executes the appropriate commands.

   Zephyr Description File Syntax
       A description file is simply a list of commands.   Whites-
       pace  (spaces,  tabs, and line breaks) is used to separate
       tokens.  The type  and  amount  of  whitespace  separating
       tokens  is irrelevant.  Comments can be delimited by # and
       newline (for line-oriented comments, e.g.  "#  this  is  a
       comment"  on  a  line by itself) or by /* and */ (e.g. "/*
       this is a comment */").

       Expressions are used by certain commands.  They  are  com-
       posed  from string literals, variable references, function
       calls, and operators.  Parentheses can be used anywhere in
       an  expression  to group expressions or increase readabil-

       String literals are specified by putting the  contents  in
       "double quotes".

       Variables  are  set using the set command (see "COMMANDS",
       below).  They are referenced in an expression by using the
       form $varname.  Some variables are set by default for each
       notice.  All other variables retain their  values  between
       notice  interpretations, so that if you set a variable, it
       retains that value until later modified.

       Functions   are   called   using    a    C-like    syntax,
       fname(expr1,expr2),  where  fname is the function name and
       exprn are the arguments.

       Binary operators use infix notation, such as "a == b".

       Some commands use an expression list (exprlist), which  is
       simply  a set of expressions separated by whitespace (e.g.
       $var1 "lit1" $var2).

   Default variables
       The following variables are always available:

       1, ...
            Numeric variables are assigned  values  corresponding
            to  that field in the notice (the body of each notice
            is conceptually an array of fields,  each  terminated
            with  a  null  character).   If the number is greater
            than the number of fields actually in the notice, the
            value  is  "".  For example, the standard zwrite mes-
            sages have two fields: $1 is the signature, and $2 is
            the text of the message.

       auth An  indication  of  the  authenticity  of the notice.
            ``yes'' means the notice is authentic,  ``no''  means
            it  is  not,  and  ``forged''  means that the message
            claimed to be authentic but the verification  of  the
            claim  failed.   The  ``forged''  indication  usually
            appears when a user has changed his Kerberos  tickets
            with  kinit(1) but has not run ``zctl sub'' to regis-
            ter this change with the Zephyr servers.

            The class of the current notice.

ZWGC(1)                                                   ZWGC(1)

       date The date on which the notice was sent.

            The default output format for the current notice

            An error message from the port read/write commands.

            The full name of  the  host  from  which  the  notice
            appears  to  have been sent.  This is not fully reli-
            able, as the information used to determine this host-
            name  is  not  guaranteed  to  be  correct  (even for
            authentic messages).

            The notice sender's name, including the zephyr  realm

            The instance of the current notice.

       kind The kind of notice.

            The full text of the message, with nulls converted to

            The number of fields in the message (a string  repre-
            sentation of a decimal number).

            The opcode of the current notice.

            The name of the output driver in use.

       port The port from which the notice was sent.

            The local zephyr realm.

            The  recipient for the current notice.  If the notice
            is a multicast (sent to several people), the  recipi-
            ent is set to ``*''.

            Usually  a  shortened  version of fullsender.  If the
            realm of the sender is equal  to  the  realm  of  the
            recipient, sender omits the realm name.

       user The    full   zephyr   name   of   the   user   (e.g.

            The current version of zwgc.

            The protocol version of the notice.

       All of these variables (except for  error,  output_driver,
       and version) are re-set before each notice is processed.

       Following  is a list of functions available for use in the
       description file.

            The contents of the current output buffer.

            Returns the value of expr, converted to lower case.

            Returns a line from the port named expr.  If there is
            no  text  waiting  on the port (e.g. the program con-
            nected to the port has not printed any output),  this
            function  will  wait until it can read a line of text
            from the port.

            Returns the value of the environment  variable  expr,
            or the empty string if it does not exist.

       lany(expr1, expr2), rany(expr1, expr2)
            Return  a number of characters equal to the length of
            expr2 from the beginning  (lany)  or  end  (rany)  of
            expr1  (e.g.  lany("1234567890","foo")  would  return
            "123").  If expr1 is a variable reference, the  vari-
            able  is  modified to remove the characters returned.
            If expr2 is longer than expr1, the value of expr1  is
            returned (and expr1 is set to "", if a variable).

       lbreak(expr1, expr2), rbreak(expr1, expr2)
            Expr2  defines  a  set  of  characters.  The function
            returns  the  longest  initial  (lbreak)   or   final
            (rbreak) string from expr1 composed of characters not
            in this set (e.g. lbreak("characters",  "tuv")  would
            return  "charac").  If expr1 is a variable reference,
            the variable is modified  to  remove  the  characters
            returned.   If  no  characters in expr2 are in expr1,
            then expr1 is returned (and expr1 is set to "", if  a

ZWGC(1)                                                   ZWGC(1)

       lspan(expr1, expr2), rspan(expr1, expr2)
            These  functions  are the negation of the break func-
            tions; the returned string consists of characters  in
            the set defined by expr2

            Returns  a string which will be evaluated identically
            to expr, but will not affect any surrounding environ-
            ments.   That  is,  any  characters which could close
            outside environments are quoted, and any environments
            in expr which are not closed at the end are closed.

            Evaluates  variable  references of the form $variable
            in expr and converts $$ to $.

            Returns the value of expr, converted to upper case.

            Returns a string that will be  displayed  exactly  as
            expr  looks.  Anything which could be mistaken for an
            environment is quoted.

            Returns expr with all environments stripped out.

            Returns the value of the zephyr variable expr, or the
            empty string if it does not exist.  [Zephyr variables
            can be set and examined with zctl(1).]

       Following is a list of operators which can be used in  the
       description file to compose expressions:

       expr1 + expr2
              String concatenation of expr1 and expr2

       expr1 == expr2
              True if the two expressions are equal, false other-

       expr1 =~ expr2
              True  if  the  regular  expression  pattern   expr2
              matches expr1.

       expr1 !~ expr2
              Negation of "=~".

       expr1 != expr2
              Negation of "=="

ZWGC(1)                                                   ZWGC(1)

       expr1 and expr2, expr1 & expr2
              True if expr1 and expr2 are both true.

       expr1 or expr2, expr1 | expr2
              True if either of expr1 or expr2 are true.

       ! expr1, not expr1
              The logical negation of expr1.

       Following is a list of the commands usable in the descrip-
       tion language:

       appendport expr1 expr2
            Creates a port called expr1.  All output to the  port
            will  be  appended  to  the  file expr2.  There is no
            input.  If the file is created, its mode  is  set  to
            read-write, owner only (no access for others).

            Exits the innermost if, case, or while block.

       case expr1 [ ((match expr [,expr ...]) | default) commands ] ... endcase
            Evaluates  expr1.   Then,  each  of the match expressions is evaluated in
            order.  The first time an expression matches expr1, then the body of com-
            mands  under  it  is  executed,  and  the  rest  of the case statement is
            skipped.  This compare is case-insensitive.  default always  matches,  so
            it  should  always  appear  as the last set of commands.  See the default
            description file for an example of use.

            Clears the output buffer (see below for details on buffering).

       closeinput expr
            Closes the file associated with expr.

       closeoutput expr
            Sends an EOF (end-of-file) to the process if expr was a port  created  by
            execport,  or  closes the file if it was created by outputport or append-

       closeport expr
            Closes both input and output of expr as defined above.

       fields variable1 ...
            sets the list of variables to be equal to the fields in the  notice.   If
            there are more variables than fields, the extra variables are left empty.

       exec exprlist
            Executes a program without any input  or  output.   A  command  named  by
            exprlist is executed.  Each expression is used as an argument to the pro-
            gram; the first expression names the program (it may be either  an  abso-

ZWGC(1)                                                   ZWGC(1)

            simple program names).

       execport expr1 exprlist
            Creates a port called expr1.  A command named by exprlist is executed, as
            described above for exec.  All output to the port is sent to the standard
            input of the process.  Reading from the port  will  return  the  standard
            output of the process.

       exit Completes  processing  of  the  current  notice.   The  remainder  of the
            description file is ignored after execution of this command.

       if expr1 then commands1 [elseif expr2 then commands2] ... [else commandsn] endif
            If expr1 evaluates to true, execute commands1, etc. [A conditional construct, similar to  the
            constructs in the C shell (csh).]

       inputport expr1 expr2
            Creates a port called expr1.  All input from the port comes from the file expr2.  There is no

       noop does nothing

       outputport expr1 expr2
            Creates a port called expr1.  The file expr2 will be truncated, or created  if  it  does  not
            exist.   All  output  to the port will be appended to the file expr2.  There is no input.  If
            the file is created, its mode is set to read-write, owner only (no access for others).

       print expr1 ...
            adds the values of the expressions to the current output buffer.  The values of  the  expres-
            sions are separated by spaces in the output.

       put [expr [exprlist]]
            Sends  data  to a port.  If expr is provided, then it is used as the port, otherwise the port
            used is the port corresponding to the default output device.  If exprlist  is  provided,  the
            expressions  in  the  list are sent to the port, separated by spaces.  If it is omitted, then
            the contents of the output buffer are sent as the data.

       set variable = expr
            sets variable equal to expr.  Variable can later be referenced by $variable.

       show text endshow
            Appends text to the output buffer.  This command is special, because the string does not need
            to  be quoted.  Whitespace at the beginning or end of the lines of text is ignored.  The end-
            show must appear as the first token on a line (it may  only  be  preceded  on  that  line  by
            whitespace).   Variable  substitutions  and formatting commands (but not expressions or func-
            tions) are processed in the text.  Example:
               this is some text
               from: $sender

       while expr do statements endwhile
            Executes statements until expr is false.

       Ports are an abstraction encompassing all I/O forms of which zwgc  is  capable.   There  are  pre-
       existing  output  ports corresponding to each of the output devices, and more ports can be created
       with the port commands described above.


       The output is usually collected in the output buffer and saved until a put command sends the  out-
       put  to  an  output  device (such as an X display or a terminal).  The output buffer is implicitly
       cleared after each notice is completely processed.

       Output devices are implemented as output ports.  A message is displayed in a device-dependent man-
       ner  when  a string is output to the port corresponding to the output device.  Formatting commands
       are embedded in the text as @ commands of the form @command(text).  Command names are  case-insen-
       sitive  and  consist  of alphanumeric characters and underscores.  Valid brackets are () [] {} and
       <>.  If the command name is empty (such as in ``@(foo)''), then a new environment with no  changes
       is  created (This is useful to temporarily change some parameter of the output, such as the font).

       The following output devices are supported:

            Sends the string to standard output exactly as is.

            Sends the string to standard error exactly as is.

            Sends the string with all formatting environments removed to standard output.

       tty  Does formatting on the message according to @ commands embedded in  the  text.   The  output,
            with  appropriate  mode-changing  sequences, is sent to the standard output.  The appropriate
            characteristics of the display are taken from the TERMCAP entry (see termcap(5)) for the ter-
            minal named by the TERM environment variable.  Supported @ commands are:
       @roman         Roman  (plain)  letters (turns off all spe-
                      cial modes).
       @b or @bold    Bold letters.  If  not  available,  reverse
                      video, else underline.
       @i or @italic  Italic letters (underlining, if available).
       @beep          "bl" termcap entry,  else  "^G"  (beep  the
                      terminal); limited to once per message.
       @l or @left    left aligned
       @c or @center  center aligned
       @r or @right   right aligned

            Other @-commands are silently ignored.

       X    Displays  one  window  per string output to the port.
            The output  is  formatted  according  to  @  commands
            embedded in the string.  Supported @ commands are:
       @roman         turns off @italic and @bold
       @b or @bold    turns on boldface
       @i or @italic  turns on italics

            context of the current style and substyle.

            The style is specific to each window.  Its  name  has
            three  dot  (``.'')  separated  fields,  which are by
            default the values of the class, instance, and recip-
            ient  variables, with all dots changed to underscores
            (``_'') and all letters converted to lowercase.   The
            style  can  be altered by setting the style variable.
            Note that it  must  always  have  exactly  two  ``.''
            characters in it.

            The  substyle is determined by @ commands in the mes-
            sage text.

            The expected geometry values are described below.

            The  fonts  and  color for a piece of text are deter-
            mined by the styles defined in the X resources  file.
            The  following  resources  relating to text style are
            used by zwgc:

                           geometry for messages of the specified

                           background  color  for messages of the
                           specified style

                           fontfamily   name  for  the  specified
                           style and substyle

                           foreground  color  for  the  specified
                           style and substyle

                           specifies the fonts for a given  font-
                           family.  size is one of small, medium,
                           or large, and face is  one  of  roman,
                           bold, italic, or bolditalic.

            The   best  way  to  get  started  in  customizing  X
            resources for zwgc is to examine the default applica-
            tion  resources  and other users' resources to under-
            stand how they specify the default appearance.


       Other X resources used by zwgc are listed below.   Entries

            zwgc*option: value
            Zwgc*option: value
            zwgc.option: value
            *option: value

       will work.

       An  entry  labeled  with zwgc*option in any of the sources
       takes precedence over Zwgc*option, which takes  precedence

       geometry       Primary POSITION (not size) geometry speci-
                      fier.   The  geometry should be of the form
                      "{+|-}x{+|-}y", specifying an (x,y) coordi-
                      nate  for a corner of the window displaying
                      the notice.  The interpretation of positive
                      and  negative  location specifications fol-
                      lows the X conventions.  A special location
                      of `c' for either x or y indicates that the
                      window should be centered along that  axis.
                      Example: a geometry of "+0+c" specifies the
                      window should be at the top of the  screen,
                      centered horizontally.

                      default if neither is set.]

       resetSaver     (logical) Primary value to force screen  to
                      unsave when a message first appears.

       ResetSaver     (logical)  Secondary  value to force screen
                      to unsave. [default True]

       reverseStack   (logical) Primary  value  to  specify  that
                      zwgc  should  attempt  to  stack WindowGram
                      windows such that the oldest messages  nor-
                      mally  show on top.  Some X window managers
                      may  silently  ignore  zwgc's  attempts  to
                      restack its windows.  This option can cause
                      some unusual interactions with  other  win-
                      dows  if  the user manually restacks either
                      the other windows or  the  WindowGram  win-

       ReverseStack   Secondary value to enable reverse stacking.
                      [default False]

       title          (string) Primary window title

       Title          Secondary window  title  [defaults  to  the
                      last  pathname  component  of  the  program
                      name, usually "zwgc"]

       transient      (logical) Primary value which determines if
                      zephyrgram windows will be created with the
                      WM_TRANSIENT_FOR  property  set.   If  this
                      resource is true, the property will be set,
                      telling  certain  windowmanagers  to  treat
                      zephyrgram    windows    specially.     For
                      instance, twm will not put  decorations  on
                      transient  windows,  mwm  will  not let you
                      iconify them, and uwm ignores the  resource

ZWGC(1)                                                   ZWGC(1)

                      [default False]

       enableDelete   (logical) If true, zwgc creates a WM_PROTO-
                      COLS   property   on   all   zgrams,   with
                      WM_DELETE_WINDOW as contents.

       EnableDelete   Secondary value to enable  WM_DELETE_WINDOW
                      protocol on zgrams [default False]

       minTimeToLive  Primary  value  which specifies the minimum
                      amount of time (``minimum time to live'') a
                      WindowGram  must be on-screen (in millisec-
                      onds) until it can be destroyed.  This fea-
                      ture is useful to avoid accidentally click-
                      ing  on  new  WindowGrams  when  trying  to
                      delete old ones.

       MinTimeToLive  Secondary   value   of  ``minimum  time  to

       iconName       (string) Primary icon name

       IconName       Secondary icon name [defaults to  the  last
                      pathname  component  of  the  program name,
                      usually "zwgc"]

       name           (string) Primary window class name

       name           Secondary window class  name  [defaults  to
                      the  last pathname component of the program
                      name, usually "zwgc"]

       synchronous    (logical) Primary X synchronous mode speci-
                      fier.   On  means to put the X library into
                      synchronous mode.

       Synchronous    Secondary  X  synchronous  mode  specifier.
                      [default is `off']

       The window class is always "Zwgc".


       Clicking  and  releasing  any button without the shift key
       depressed while the pointer remains  inside  a  WindowGram
       window  will  cause it to disappear. If the pointer leaves
       the window while the button is depressed, the window  does
       not  disappear;  this provides a way to avoid accidentally
       losing messages.

       If the control button is held down  while  clicking  on  a
       WindowGram, then that WindowGram and all windowgrams under
       the point where the button is released will be erased.

ZWGC(1)                                                   ZWGC(1)

       the  mouse,  it  is  possible for your subscriptions to be
       lost.  If zctl retrieve returns nothing, then issue a zctl
       load  command  to re-subscribe to your default set of sub-
       scriptions.  If you use znol, then znol -q & will  restore
       the subscriptions you need for znol.

       Portions  of  the  text  of  a message may be selected for
       "pasting" into other X applications by using the shift key
       in  cooperation  with  the  pointer  buttons.  Holding the
       Shift key while depressing Button1 (usually the left  but-
       ton)  will  set  a  marker  at the text under the pointer.
       Dragging the pointer with  Shift-Button1  still  depressed
       extends the selection from the start point, until the but-
       ton is released.  The end of the  selection  may  also  be
       indicated  by  releasing  Button1,  holding down the Shift
       key, and pressing Button3 (usually the  right  button)  at
       the desired endpoint of the selection.  The selection will
       appear with the text and background colors reversed.


       If zwgc  receives  a  WM_DELETE_WINDOW,  it  destroys  the
       zephyrgram as if it were clicked on.

       If a zephyrgram is unmapped, it is removed from the stack-
       ing order used by reverseStack.


       zwgc is normally invoked from  /usr/athena/lib/init/login,
       $HOME/.xsession,  or  /usr/athena/lib/init/xsession in the
       foreground and with no arguments. When it has successfully
       set  your location, it will put itself into the background
       (unless the -nofork option has been  specified).  At  this
       point  it  is  safe  to invoke additional zephyr commands,
       such as znol(1).  (You can also put these commands in  the
       initprogs  Zephyr  variable; the value of this variable is
       passed as the argument to the system(3) library call  dur-
       ing  initialization.)   zwgc will exit with an exit status
       of 0 if it was able to open the X display successfully  or
       1  if it couldn't open the display and the Zephyr variable
       fallback was set to  ``false''.  If  fallback  is  set  to
       ``true'',  zwgc  will fall back to ``ttymode'' (making the
       tty driver the default output device) if it can't open the
       X  display.  If fallback is not set and the display cannot
       be opened, zwgc prints an explanatory  message  and  exits
       with a status of 1.

       If  the -ttymode option is specified, zwgc will ignore any
       X display and use  the  terminal  as  its  primary  output
       device.   This  flag overrides any setting of the fallback

       previous version of zwgc.

       zwgc  will  exit  cleanly  (unset location and cancel sub-
       scriptions) on:
            XIOError (with a message to stderr)
       SIGHUP is what it expects to get upon logout.   Also,  the
       signals  SIGINT,  SIGQUIT, and SIGTSTP are ignored because
       they can be sent inadvertently, and  bizarre  side-effects
       can  result.   If  you  want them to be acted on, then run
       zwgc -nofork &


       In order to allow some  special  user  controls  over  the
       behavior  of  zwgc,  certain Zephyr control notices can be
       sent directly to zwgc using the zctl(1) program. Currently
       implemented controls are

       wg_read        tell  zwgc  to re-read the current descrip-
                      tion file.

       wg_shutdown    tell zwgc to cancel all  subscriptions  and
                      stop  acting  on  incoming  notices.   zwgc
                      saves the subscriptions that were in effect
                      at  the time of the shutdown so that it can
                      restore them later if needed.

       wg_startup     tell zwgc to restart  from  being  shutdown
                      and reinstall the saved subscriptions.

       Other control messages may be implemented in the future.


       For    an    example    of   a   description   file,   see
       /usr/athena/lib/zephyr/zwgc.desc.  For  an  example  of  X
       resources, see /usr/athena/lib/zephyr/zwgc_resources.


       The  X  selection code can highlight the wrong portions of
       messages containing formatted text placed with  the  @cen-
       ter() or @right() directives.

       If  you  are  using  Kerberos  support and get new tickets
       (using ``kinit''), you must send a subscription notice  to
       the   server   (using   a  command  such  as  ``zctl  load
       /dev/null'') or all received Zephyr notices will appear to
       be unauthentic.  (If all received Zephyr notices appear to
       be forged, your tickets have probably  expired,  in  which
       case  you  must  get  new tickets and then run ``zctl load
