NAME

       signify - Program to generate semi-random signatures

SYNOPSIS

       signify [--fifo=$HOME/.signature] [--input=file] [--debug]

DESCRIPTION

       Signify  will take a signature description file ( ~/.signify or whatever file is specified
       by the --input=<file> option ) and create a random  signature  based  on  the  information
       contained  therein.   This allows the ability to do such things as pick a random quote for
       each message sent.

       Signify, by default, will write the generated signature to standard output from  where  it
       can  be redirected to overwrite the .signature file.  Alternatively, Signify can pipe it's
       output to a given 'fifo'.  Each read from that file will return a different signature.

       To use the FIFO feature, delete the current "$HOME/.signature" file and start  Signify  in
       the  background  like  "signify  --fifo=$HOME/.signature  &".  With this running, try "cat
       $HOME/.signature" a few times.  A different signature will be returned each time.   (Note:
       This feature will probably work only on unix systems.)

       The  --debug  switch  causes  Signify  to generate messages on what it is doing to stderr.
       This switch is only meant to be useful to the program's maintainers.

CONFIGURATION

       The definition for the generated signatures is contained entirely within the .signify file
       contained  in  the  user's  home directory.  Any completely empty lines (lines with even a
       single space are considered part of the signature data) and those lines  starting  with  a
       hash  character  (#) are completely ignored.  Those lines starting with a percent sign (%)
       are considered commands and affect the way Signify behaves.

       Perl Command Substitution

       Signify can execute an arbitrary perl code fragment during  the  initial  reading  of  the
       configuration  file.  This can be used, for example, to choose values or text depending on
       the environment in which Signify is being run.  To use this feature,  simply  enclose  the
       desired  perl  code  in back-tics (i.e. `perl code`).  Whatever the perl code evaluates to
       will be substituted in that spot.  No further  variable  substitutions  are  made  on  the
       resulting  text.  Signify is intelligent enough to recognize two back-tics together (often
       used as a better looking quotation mark) as not being a  code  fragment.   Thus,  writting
       something  like  "``Stop,''  she  said."  will  appear as expected.  Note: The entire code
       fragment must be contained on a single line of the input file.

       Defining Variables

       Signify will substitute variables within each line of the signature in much the  same  way
       as the shell would.  Any sequence of $WORD; will be replaced by the value corresponding to
       the name "WORD".  Case is significant but the trailing semicolon may  be  omitted  if  the
       next character is not a letter, digit, or underscore.  By default, these variables look up
       values inside the environment variables, but can also be defined or redefined  within  the
       .signify file itself with a command such as:

           % $email=myid@mycompany.com

       Everything  after  the  equal  sign (=) is considered part of the value.  Variables can be
       used in the definition of other variables.  As a special  case,  $$  will  evaluate  to  a
       single dollar sign ($).

       The special variable SIGWIDTH can be used to set the desired output width of the generated
       signature.  By default, this variable has the value "79".  There is also a BLANK  variable
       you can place on a line to create a totally empty line when the signature is output.

       Including Other Files

       You  can  tell  Signify  to  read another file in place of the current line with a command
       like:

           % include $HOME/.signify-quotes

       For convienence, you can use a tilde (~) instead of $HOME to read a file relative to  your
       home directory.

       Creating Alternates

       An  unlimited  number  of  "alternates"  can  be  specified by using the "{", "|", and "}"
       commands.  When the signature is generated, only one of all the possible  alternates  will
       be output.  For example:

           % {
           This is the first possibility.
           % |
           This is the second possibility.
           % |
           This is the third (and last) possibility.
           Note that alternatives can span multiple lines.
           % }

       Creating Columns

       Signify  will  automatically  create side-by-side columns with nice, even spacing by using
       the "(", "|", and ")" commands.  When output, everything will be padded out with spaces to
       fit nicely on the line.  For example:

           % (
           This is the
           first column.
           % |
           This is the second.
           % |
           This is the third
           (and last) column.
           % )

       Nesting Sections

       Alternates and columns can be nested to any depth, though this can quickly become unwieldy
       and may not work exactly as expected, especially with columns.  As a  general  rule,  only
       supply  alignment options (eg. "center", "right") at the most outside level to do any text
       formatting.  For example, if supplying multiple "alternates"  within  a  column,  put  the
       alignment options on the column and not on the alternates.

       Section Command Options

       The  "alternates"  and  "columns" commands can take options to alter how they behave.  The
       following is a list of supported options and what they do, though not all have meaning for
       both  types of section.  Multiple options can be specified by separating them with a comma
       (,).

       bottom push the following lines of text to the bottom of a column  should  it  have  fewer
              lines  than  the  longest  column.   This  option  has  no  meaning to "alternates"
              sections.

       center adjust the following lines to be centered on the page or in the column.  When  used
              in  an  "alternates" section, an additional "=<number>" can be used to specify what
              column to center around instead of the middle of the page.

       exec   treat the following lines not as text to be included in the  column  or  alternate,
              but  as  commands  to  be executed by the shell.  For each command executed, if its
              return status is 0 then the output it produced is included at that point, otherwise
              the  output  is discarded.  Any included text is then aligned, etc. as usual.  This
              command is most useful for inserting random quotes generated by  programs  such  as
              fortune(6).

       left   adjust  the  following  lines  so they sit at the left margin.  This is the default
              horizontal alignment and most closely reflects how the lines are entered  into  the
              .signify file itself.  Note that pad spaces will still be placed on both sides of a
              column with this type of alignment unless the minwidth option is also specified.

       minwidth
              do not pad the left and right sides of this  column  when  placing  next  to  other
              columns.   This is useful for building column separator lines and the like that are
              not really part of the  content.   This  option  has  no  meaning  to  "alternates"
              sections.

       repeat output the following lines multiple times to fill all lines in the column.  This is
              useful for building column separator lines and the like that are  just  a  repeated
              sequence.  A multi-line sequence can be specified and only those lines necessary to
              fill the column will be output.  The entire sequence will be output in its entirety
              at least once, however.  This option has no meaning to "alternates" sections.

       right  adjust  the  following lines so they sit at the right margin.  Note that pad spaces
              will still be placed on both sides of a column with this type of  alignment  unless
              the minwidth option is also specified.

       top    push  the following lines of text to the top of a column should it have fewer lines
              than the longest column.  This is the default action if no  vertical  centering  is
              specified.  This option has no meaning to "alternates" sections.

       vcenter
              push  the following lines of text in the vertical center of a column should it have
              fewer lines than the longest column.  This option has no  meaning  to  "alternates"
              sections.

       weight=<number>
              change the likelihood a given alternate will be chosen.  The chance of any specific
              alternate being chosen is the given <number> divided by the total of  all  weights.
              If  not  specified,  the  weight defaults to 1.0.  Decimal numbers and numbers less
              that 1.0 are allowed.  This option has no meaning to "columns" sections.

THE COST OF FREE SOFTWARE

       Let's face it: Somebody has to pay for all software that gets written.  Whether it is  the
       time  donated  by  the programmer or the salary donated by the company, everything has its
       cost.  Signify has been made available to the general public in the hope that it  will  be
       useful  and  thus help raise the visibility of the people that sponsored its creation.  In
       this way, the cost of creating Signify is offset by the publicity gained.  If you use this
       program and would like to further the development of such software, it is asked (but by no
       means required) that you put something like the following in the quotes  section  of  your
       .signify file.

           % | center, weight=0.1
           Generated by $PROGRAM.  For this and more, visit $WEBSITE

       (for single-line quote)  or  (for multi-line in a column)

           % | weight=0.1
           This signature was automatically generated with
           $PROGRAM.  For this and other cool products,
           check out $WEBSITE

       These are weighted very low (though you are more than welcome to increase these weightings
       :-) and will thus show up in your signature only occasionally.  The variables are  defined
       internal  to  Signify  and provide the program name (including version number) and the web
       site where it can be found.  We thank you for your support!
