OK, here is the latest revision of Pcal. There are some new flags, but the
most significant change is the addition of elementary cpp-like functionality
to the date file. The date file directory and program defaults may be
overridden via environment variables (or their equivalents on VMS) - see
the ReadMe file for more details.
Thanks to Mark Kantrowitz, Joe Brownlee, and Eric Hammond for their
contributions and suggestions.

This is still another new and improved release (2.1) of the infamous Pcal
program. The changes this time are:
1) Elementary cpp-like functionality has been added; the date file
now supports define|undef, if{n}def ... { else ... } endif, and
include:
ifdef meetings
include meetings.dat
undef meetings
endif
Symbols may be {un}defined on the command line via the new -D
and -U options described below; symbol names are treated in a
case-insensitive manner. "define" alone deletes all symbol
definitions; "ifdef" alone is always false; "ifndef" alone is
always true.
The names of files to be included may be optionally surrounded
by "" or <>; non-absolute path names are taken to be relative
to the directory where the file containing the include directive
exists. The Un*x flavor is smart enough to translate file names
starting with "~/".
2) Pcal now looks for environment variable (global symbol on VMS)
PCAL_OPTS, which is parsed for command line options; flags set
there override the program defaults but are overridden by values
set in the date file or explicitly on the command line:
setenv PCAL_OPTS "-t Times-Bold" (Un*x)
$ PCAL_OPTS == "-t Times-Bold" (VMS)
3) Pcal also looks for environment variable (logical name on VMS)
PCAL_DIR which points to the default directory for the calendar/
CALENDAR.DAT file.
setenv PCAL_DIR "/u4/users/awr/pcal" (Un*x)
$ define PCAL_DIR "DISK11:[AWR.PCAL]" (VMS)
In response to many requests, Un*x pcal looks for .calendar; if
that does not exist, it looks for calendar as before.
4) The -D and -U flags have been added to define or undefine symbols
for the preprocessor; if these are specified on the command line,
they take effect prior to reading the date file. -D alone clears
all previously-defined symbols.
pcal -D meetings (Un*x)
$ pcal -"D" meetings (VMS)
5) The -L, -C, and -R flags have been added to specify left, center,
and right foot strings. Foot strings consisting of multiple words
should be specified in single or double quotes:
opt -C "Languages and Tools Group"
6) The '-' (also '--') dummy flag has been added to disambiguate
cases such as the following:
pcal -t 9 90
which may now be specified as
pcal -t - 9 90 or pcal -t -- 9 90
7) As many have noticed, Pcal used to overstrike multiple text lines
for the same date if the lines were not contiguous in the date
file; this has been fixed. Also, the text accompanying holidays
is written in the otherwise-unused space adjacent to the date.
The accompanying file called "ReadMe.orig" came with the original distribution
as README and states this program is copyrighted but with permission to modify
and redistribute.

Additional note: This distribution includes a VMS HELP file written by
Richard Dyson. Countless other people worked on pcal long before me; see
the ReadMe.orig file and topline comments in pcal.c; special thanks to
Mark Kantrowitz, Joe Brownlee, and Eric Hammond for their contributions
and suggestions which I have incorporated into release 2.1.

"Pcal" is a program to print PostScript calendars for any month and year.
By default, it looks for a file in the home directory named "calendar"
for entries with leading dates matching dates on the calendar, and prints
any following text under the appropriate day.
The program may be a little System V flavored (getopt, time routines)
but should be easily portable to other vintages of UNIX.
Pcal is the combined effort of several people, most notably Patrick Wood
of Pipeline Associates, Inc. for the original PostScript code and Bill
Vogel of AT&T for the calendar file mechanism. My part was simple
translation to a "C" program, the addition of a couple options and a more
generalized date searching routine (oh yes, and a manual page :-).
The original calendar PostScript was Copyright (c) 1987 by Patrick Wood
and Pipeline Associates, Inc. with permission to modify and redistribute.
Please retain this README file with the package.

# Sample calendar file for pcal
#
# This should be ~/calendar on Unix, SYS$LOGIN:CALENDAR.DAT on VMS
#
# Valid entries are of the following forms:
#
# opt <options>
# year <year>
# <month_name> <day>{*} {<text>}
# <month><sep><day>{<sep><year>}{*} {<text>}
#
# where:
# <options> := one or more valid command-line options (except -e and -f)
# <month_name> := first 3+ characters of name of month (in English)
# <sep> := one or more non-numeric, non-space, non-'*' characters
# <text> is the text to be printed in the calendar box
# <day>, <month>, and <year> are appropriate integers
#
# whitespace is to be used/avoided as implied by the above productions
# '*' flags the date as a holiday (to be printed in gray)
# comments run from '#' through end-of-line
# A sample "opt" line to change the fonts and output file names and to print
# only Sundays in gray:
#
#opt -d Helvetica-Bold -t Helvetica-Bold -o myfile.ps -b all -g sun
year 1990 # set year explicitly
5/28* Memorial Day (observed) # '*' prints holiday in gray
5/31 Memorial Day
7/4/90* Independence Day # full date format
Sep 3* Labor Day # month written out
10/8* Columbus Day (observed)
10/12 Columbus Day
11/22* Thanksgiving
11/23* # holiday without text
12/24* # Christmas Eve
12/25* Christmas

/*
* pcal.c - generate PostScript file to print calendar for any month and year
*
* The original PostScript code to generate the calendars was written by
* Patrick Wood (Copyright (c) 1987 by Patrick Wood of Pipeline Associates,
* Inc.), and authorized for modification and redistribution. The calendar
* file inclusion code was originally written in "bs(1)" by Bill Vogel of
* AT&T. Patrick's original PostScript was modified and enhanced several
* times by others whose names have regrettably been lost. This C version
* was originally created by Ken Keirnan of Pacific Bell; additional
* enhancements by Joseph P. Larson, Ed Hand, and Andrew Rogers (who also
* did the VMS port), and Mark Kantrowitz. Many thanks also to Joe Brownlee
* and Eric Hammond for their suggestions.
*
* Revision history:
*
* 2.1 MK/AWR 08/27/90 support -L, -C, -R, -n options;
* print holiday text next to date
*
* AWR 08/24/90 incorporate cpp-like functionality;
* add -D and -U options; save date file
* information in internal data structure;
* look for PCAL_OPTS and PCAL_DIR; look
* for ~/.calendar and ~/calendar
*
* 2.0 AWR 08/08/90 included revision history; replaced -r
* flag with -l and -p; replaced -s and -S
* flags with -b and -g; recognize flags
* set in date file; translate ( and ) in
* text to octal escape sequence; usage()
* message condensed to fit 24x80 screen
*
* Parameters:
*
* pcal [opts] generate calendar for current month/year
*
* pcal [opts] yy generate calendar for entire year yy
*
* pcal [opts] mm yy generate calendar for month mm
* (Jan = 1), year yy (19yy if yy < 100)
*
* pcal [opts] mm yy n as above, for n consecutive months
*
* Output:
*
* PostScript file to print calendars for all selected months.
*
* Options:
*
* -b <DAY> print specified weekday in black
* -g <DAY> print specified weekday in gray
* (default: print Saturdays and Sundays in gray)
*
* -d <FONT> specify alternate font for day names
* (default: Times-Bold)
*
* -n <FONT> specify alternate font for notes in boxes
* (default: Helvetica-Narrow)
*
* -t <FONT> specify alternate font for titles
* (default: Times-Bold)
*
* -D <SYM> define preprocessor symbol
* -U <SYM> un-define preprocessor symbol
*
* -e generate empty calendar (ignore date file)
*
* -f <FILE> specify alternate date file (default:
* ~/.calendar on Un*x, SYS$LOGIN:CALENDAR.DAT
* on VMS; if environment variable [logical
* name on VMS] PCAL_DIR exists, looks there
* instead)
*
* -o <FILE> specify alternate output file (default:
* stdout on Un*x, CALENDAR.PS on VMS)
*
* -L <STRING> specify left foot string (default: "")
* -C <STRING> specify center foot string (default: "")
* -R <STRING> specify right foot string (default: "")
*
* -l generate landscape-mode calendars
* -p generate portrait-mode calendars
* (default: landscape-mode)
*
* There are many ways to specify these options in addition to using the
* command line; this facilitates customization to the user's needs.
*
* If the environment variable (global symbol on VMS) PCAL_OPTS is
* present, its value will be parsed as if it were a command line.
* Any options specified will override the program defaults.
*
* All but the -e, -f, -D, and -U options may be specified in the date
* file by the inclusion of one or more lines of the form "opt <options>".
* Any such options override any previous values set either as program
* defaults, via PCAL_OPTS, or in previous "opt" lines.
*
* Options explicitly specified on the command line in turn override all
* of the above.
*
* The -b, -d, -g, -n, -o, -t, -C, -L, and -R flags may be specified at
* any point to reset the corresponding option to its default. -D may
* be specified without an argument in order to un-define all symbols.
*
* Parameters and flags may be mixed on the command line. In some cases
* (e.g., when a parameter follows a flag without its optional argument)
* this may lead to ambiguity; the dummy flag '-' (or '--') may be used
* to separate them, i.e. "pcal -t - 9 90".
*
* Simple cpp-like functionality is provided. The date file may include
* the following commands, which work like their cpp counterparts:
*
* define <sym>
* undef <sym>
*
* if{n}def <sym>
* ...
* { else
* ... }
* endif
*
* include <file>
*
* Note that these do not start with '#', which is reserved as a comment
* character.
*
* "define" alone deletes all the current definitions; "ifdef" alone is
* always false; "ifndef" alone is always true. All defined symbols are
* treated in a case-insensitive manner.
*
* The file name in the "include" directive may optionally be surrounded
* by "" or <>.

1 PCAL
Pcal generates PostScript to produce landscape or portrait
orientated calendars for any month and year. The defaults for
month and year are the current month and year.
VMS Version
Execution format:
pcal [options] [mm yy] [n]
If a file named CALENDAR.DAT resides in the caller's home
directory (or in a directory defined by the logical name PCAL_DIR,
if it exists), it will be searched for lines with leading dates
matching the requested month and year (current by default). Any
text following the date will be printed on the calendar under the
appropriate day of the month. Dates in the CALENDAR.DAT file may
consist of a numeric or alpha month (at least the first 3
characters for month names) followed by a numeric day and
optionally followed by a year. Any non-numeric character may
separate numeric dates. Holidays may be flagged by following the
date immediately with '*'; this will cause the date to be printed
in gray. Lines in the CALENDAR.DAT file consisting of "year xxxx"
(where xxxx is a numeric year) can be used to set the year for
following entries. This assumes that the following entries do not
contain a year; any date entries containing year information will
set the remembered year to that year. Lines consisting of
"opt <options>" can be used to override defaults for all command-
line flags except -e, -f, -D, and -U; any flags set in this manner
are themselves overridden by flags specified explicitly on the
command line. Comments ('#' through end-of-line) are permitted.
Example:
# sample CALENDAR.DAT file - Raytheon holidays and exempt paydays, 1990
opt -t Helvetica-Bold -d Helvetica-Bold # override default fonts
year 1990 # set default year
7/4* Independence Day # '*' flags 7/4 as holiday
7/12/90 Exempt payday # full numeric date
Aug 16 Exempt payday # alternate date format
9/3* Labor Day
9/20 Exempt payday
10/8* Columbus Day (observed)
10/25 Exempt payday
11/20 Exempt payday
11/22* Thanksgiving
11/23*
12/13 Exempt payday
12/24*
12/25* Christmas
Release 2.1 of pcal adds rudimentary cpp-like functionality to the
date file, supporting define|undef, if{n}def ... {else ...} endif,
and include:
define meetings
ifdef meetings
include meetings.dat
undef meetings
endif
Symbol names are case-insensitive. It is not an error to "undef"
an undefined symbol, nor to "define" a previously-defined one.
"ifdef" alone is always false; "ifndef" alone is always true.
The name of the file in the "include" directive may optionally be
surrounded by either "" or <>, both of which are ignored. If the
name is not an absolute path, it is taken to be relative to the
directory where the file containing the directive is located.
Release 2.1 also looks for global symbol PCAL_OPTS; if defined,
its contents are parsed as command-line flags. These override the
program defaults, but are overridden by any specified via "opt"
lines in the date file or on the command line. Example:
$ define PCAL_OPTS "-n Helvetica -D meetings" ! login.com
$ pcal -"U" meetings 9 90 ! un-define symbol at runtime
2 parameters
mm yy n
"mm" and "yy" are numeric values of the month (1-12) and year
(0-99) (i.e., July 1990 would be 7 90). If you just include the
"yy" option, an entire 12 months of calendars will be generated.
A specific month can be produced by including the "mm" parameter.
The "n" parameter will produce the "n" consecutive months of
calendars starting with the requested month.
The following flags may be specified (in increasing order of
precedence) in global symbol PCAL_OPTS, in "opt" lines in the date
file (all but -e, -f, -D, -U), or on the command line. Any flag
which normally takes an argument may be specified without the
argument; this resets its value to the program default. (-D
alone thus clears all defined symbols; -U alone has no effect.)
The '-' flag has been added to disambiguate cases where an
argument-less flag has been specified immediately before a numeric
parameter:
$ pcal -t - 9 90
2 -e
Print an empty calendar (i.e., do not print entries from a
CALENDAR.DAT file.)
2 -f <FILE>
Directs pcal to use the file name <FILE> as the input file in
place of the default CALENDAR.DAT file in the callers home
directory or in the directory specified by logical name PCAL_DIR.
2 -o <FILE>
Directs pcal to write the PostScript calendar into FILE
(default: CALENDAR.PS in the current directory.)
2 -l
This will cause the output to come out in landscape mode
(default).
2 -p
This will cause the output to come out in portrait mode
instead of landscape mode.
2 -b <DAY> | all
This will cause all dates on weekday DAY to be printed in
black; "-b all" causes all dates to be printed in black unless
explicitly flagged as a holiday.
2 -g <DAY> | all
This will cause all dates on weekday DAY to be printed in
gray; "-g all" causes all dates to be printed in gray. Default is
to print Saturdays and Sundays in gray and other dates in black.
2 -t <FONT>
This option can be used to change the font used to print the
title (i.e. $ pcal -t "Times-Roman"). The default is Times-Bold.
2 -d <FONT>
This option is the same as -t except that the font used to
print the day numbers is changed. The default is Times-Bold.
2 -n <FONT>
This option is the same as -n except that the font used to
print the notes in the calendar boxes is changed. The default is
Helvetica-Narrow.
2 -"L" <STRING>
This will cause STRING to be printed as a left footer.
2 -"C" <STRING>
This will cause STRING to be printed as a center footer.
2 -"R" <STRING>
This will cause STRING to be printed as a right footer.
2 -"D" <SYM>
This will define symbol SYM prior to reading the date file;
-D alone clears all defined symbols.
2 -"U" <SYM>
This will undefine symbol SYM prior to reading the date file.

.SH DESCRIPTION
.I Pcal
generates PostScript to produce landscape or portrait calendars for any
month and year. The arguments
.BR month ,
.BR year ,
and
.BR nmonths ,
if provided, should be numeric. The month should be in the range 1 - 12,
and year should be specified as 1 or 2 digits or as the full 4 digit year.
.P
If no numeric arguments are provided, the current month and year will be
generated.
.P
If one numeric argument is provided, it is interpreted as the year; the
entire year will be generated. Otherwise,
.I nmonth
months, starting with
.I month
and
.I year,
will be generated.
.PP
If a file named
.I \.calendar
or
.I calendar
(for compatibility with older versions)
exists in the caller's home directory (or in the directory pointed to by
environment variable PCAL_DIR), it will be searched for lines with
leading dates matching the requested month and year (current by default).
Any text following the date will be printed on the calendar under the
appropriate day of the month. Dates in the
.I \.calendar
file may consist of a numeric or alpha month (at least the first 3 characters
for month names) followed by a numeric day and optionally followed by a
year. Any non-numeric character may separate numeric dates. Holidays may
be flagged by following the date immediately with '*'; this will cause the
date to be printed in gray.
.PP
Lines in the
.I \.calendar
file consisting of "year xxxx" (where xxxx is a numeric year) can be used
to set the year for following entries. This assumes that the following
entries do not contain a year; any date entries containing year information
will set the remembered year to that year.
.PP
Lines in the
.I \.calendar
file consisting of "opt <options>" can be used to override the defaults for
any command-line flags except -e, -f, -D, and -U. Any flags specified in this
manner
are, in turn, overridden by those specified explicitly on the command line.
.PP
Comments ('#' through end-of-line) are supported.
.PP
Release 2.1 of pcal adds rudimentary cpp-like functionality to the
date file, supporting
.BR define |
.BR undef ,
.B if{n}def ... {else ...} endif,
and
.BR include.
Note that these are not preceded by '#' as they are in C.
.PP
Symbol names are case-insensitive. It is not an error to "undef"
an undefined symbol, nor to "define" a previously-defined one.
.PP
"ifdef" alone is always false; "ifndef" alone is always true.
.PP
The name of the file in the "include" directive may optionally be
surrounded by either "" or <>, both of which are ignored. If the
name is not an absolute path, it is taken to be relative to the
directory where the file containing the directive is located.
.I Pcal
is smart enough to translate "~/" to the user's home directory.
.PP
.I Pcal
has many options:
.P
.TP
.B \-e
Print an empty calendar. Do not print entries from a calendar file.
.TP
.B \-f <cal>
Directs
.I pcal
to use the file name <cal> as the input file in place of the default
.I \.calendar
file in the callers home directory (or directory pointed to
by PCAL_DIR).
.TP
.B \-o <file>
Directs
.I pcal
to write the output to <file> instead of to stdout.
.TP
.B \-l
This will cause the output to come out in landscape mode (default).
.TP
.B \-p
This will cause the output to come out in portrait mode.
.TP
.B \-b <day> | all
This will cause all dates falling on weekday <day> to be printed in black;
"-b all" causes all weekdays to be printed in black.
.TP
.B \-g <day> | all
This will cause all dates falling on weekday <day> to be printed in gray;
"-g all" causes all weekdays to be printed in gray.
.IP
(The default for the -b and -g flags is to print Saturdays and Sundays in
gray and other days - unless flagged as holidays - in black.)
.TP
.B \-t <titlefont name>
This option can be used to change the font the title
is printed in. (ie. pcal -t Times-Roman).
.TP
.B \-d <dayfont name>
This option is the same as -t except that the font used
to print the day numbers is changed.
.TP
.B \-n <notesfont name>
This option is the same as -n except that the font used
to print the notes in the calendar boxes is changed.
.TP
.B \-D <symbol>
This option defines the named symbol prior to reading the date file.
.TP
.B \-U <symbol>
This option un-defines the named symbol prior to reading the date file.
.TP
.B \-L <string>
This option causes the accompanying string to be printed as a left footer.
.TP
.B \-C <string>
This option causes the accompanying string to be printed as a center footer.
.TP
.B \-R <string>
This option causes the accompanying string to be printed as a right footer.
.IP
Any option which normally takes an argument may be specified without
the argument in order to reset the value to the program default.
.B \-D
alone clears all the defined symbols;
.B \-U
alone has no effect. The
.B \-
(or
.BR \-\- ,
System V people)
flag may be used to disambiguate cases such as "pcal -t 9 90"; this
could be written instead as "pcal -t - 9 90" or "pcal -t -- 9 90".
.IP
If the environment variable PCAL_OPTS is defined, its contents are
parsed as a command line. Flags set via PCAL_OPTS override the
program defaults, but are overridden by flags set via "opt" lines
in the date file or explicitly on the command line.
