..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
..BR month
value should be in the range 1 \- 12, and the
..BR year
value should be specified as 1 or 2 digits or as the full 4 digit year.
If no numeric arguments are provided, the calendar for the current month
and year will be generated.
..PP
If one numeric argument is provided, it is interpreted as the
..BR year
value, and calendars for the entire year will be generated. Otherwise,
..BR nmonth
months, starting with
..BR month
and
..BR year ,
will be generated.
..PP
For whole-year calendars (i.e. the
..B \-w
option is given), the command line arguments are interpreted somewhat
differently. By default, all months in the current year are printed, starting
with January. If the
..B month
argument alone is given, it is expected to be the desired
..B year
to print, and prints all of the months in the given year. If both
..BR month " and " year
are given, then 12 consecutive months are printed starting at the given
month and year. If the
..BR month ", " year ", and " nmonths
arguments are all present, printing begins with the given month and year and
..B nmonths
months are printed, rounded up to the nearest multiple of 12.
..PP
..B The Date File
..PP
By default,
..I pcal
simply prints an empty calendar. Its real power is in its ability to place
``events'' in appropriate days on the calendar, thus allowing the user to
create personalized calendars. This is achieved through the use of the
``date file''.
..PP
The date file is named
..IR \.calendar " (" pcal.dat
under MS-DOS),
or
..I calendar
for compatibility with older versions.
..I Pcal
will look in several places for such a file. First, if a file called
..I \.calendar
exists in the caller's home directory, it is used. Next, if such a file exists
in the directory indicated by
environment variable
..BR PCAL_DIR
(or the current directory if no such variable is defined), it is used.
Finally, the directory where the
..I pcal
executable resides will be checked. If no date file is found, an empty
calendar is printed.
..PP
If a date file is found, it will be searched for lines with
leading dates matching the requested month and year.
Any text following the dates found will be printed on the calendar under the
appropriate day of the month. Dates in the
..I \.calendar
file may be expressed in any of several formats:
..PP
..ft CW
..nf
X <ordinal> <day_spec> in <month_spec>{*} {<text>}
X <day_spec> <prep> <date_spec>{*} {<text>}
X <date_spec>{*} {<text>}
..fi
..ft
..PP
Where:
..PP
..nf
X <month_name> := first 3+ characters of name of month, or ``all''
X <month_spec> := <month_name>, or ``year''
X <day_spec> := first 3+ characters of name of weekday, ``day'',
X ``weekday'', ``workday'', ``holiday'', ``nonweekday'',
X ``nonworkday'', or ``nonholiday''
X <ordinal> := any ordinal number (``1st'', ``2nd'', etc.), ``first'' ... ``fifth'',
X ``last'', ``odd'', ``even'', or ``all''
X <prep> := ``before'', ``preceding'', ``after'', ``following'',
X ``on_or_before'' (``oob''), or ``on_or_after'' (``ooa'')
X <sep> := one or more non-numeric, non-space, non-'*' characters
X <month> := a numeric month (1-12)
X <day> := day of month (1-31)
X <year> := a numeric year
..fi
..ft
..PP
If the
..B \-A
option (American date formats, the default) is given:
..PP
..nf
X <date_spec> := [ <month_name> <day> | <month><sep><day>{<sep><year>} ]
..fi
..PP
If the
..B \-E
option (European date formats) is given:
..PP
..nf
X <date_spec> := [ <day> <month_name> | <day><sep><month>{<sep><year>} ]
..fi
..PP
..I Pcal
also allows format specifiers in both the text and foot strings (see the
..BR \-L ,
..BR \-C ,
and
..B \-R
options below); each will be replaced by a corresponding
string as outlined in the table below. Most of these are derived from the
..ft CW
strftime()
..ft
function; the
..BR %l " and " %[o0+\-]
format specifiers are specific to
..IR pcal :
..PP
..nf
X %a abbreviated weekday
X %A full weekday
X %b abbreviated month name
X %B full month name
X %d day of month (1-31)
X %j day of year (1-366)
X %l days left in year (0-365)
X %m month (1-12)
X %U week number (0-53)
X %W week number (0-53)
X %y year w/o century (00-99)
X %Y year w/century
X %% `%' character
X
X %o print number as ordinal
X %0 print number with leading zeroes
X %+ use following month or year
X %\- use previous month or year
..fi
..PP
The
..B %U
format specifier considers the first logical Sunday (the first day
of the week as printed; see the
..B \-F
option below) of the year as the first day of week number 1; the
..B %W
specifier uses the first logical Monday instead. This is an
extension of the behavior of the
..ft CW
strftime()
..ft
function.
..PP
The
..B %o
format specifier prints a number as an ordinal, with the appropriate
suffix (``st'', ``nd'', ``rd'', or ``th'' in English) appended; for example,
..B %od
prints the day of the month as ``1st'', ``2nd'', ``3rd'', etc.
..PP
Unlike
..ft CW
strftime(),
..ft
..IR pcal 's
default is to print numbers (except
..BR %y )
without leading zeroes. If leading zeroes are desired, the `0'
prefix may be used; for example,
..B %0j
prints the day of year as 001-365.
..PP
The
..BR %+ " and " %\-
format specifiers direct
..I pcal
to substitute the following or previous month or year for the following
..B [bBmyY]
specifier; for example,
..B %+B
prints the name of the following month.
..PP
Examples:
..PP
..ft CW
..nf
X last Monday in May* Memorial Day Holiday
..sp
X all Fridays in Oct Status Meeting, 11 AM
X first workday in all %-B progress report due
X all Fri in all Time card due, 3 PM
X all Monday in all Fiscal week %0W
X -2nd workday in all Schedule for %+B due
X Fri on_or_before all 15 Pay Day
X even Fridays in year Pay Day
X 183rd day of year mid-year (%l days left)
..sp
X Tue after first Mon in Nov Election Day (USA)
..sp
X 4th Thu in Nov* Thanksgiving
X Fri after 4th Thu in Nov* Day after Thanksgiving
..sp
X 12/25/90* Christmas # American
X 25.12.90* Christmas # European
..sp
X Dec 25* Christmas # American
X 25 Dec* Christmas # European
..fi
..ft
..PP
Any non-numeric character may separate numeric dates. Holidays may
be flagged by following the date immediately with `*'
as in the examples above; this will cause the
date to be printed in gray.
``Each'' and ``every'' are accepted as synonyms for ``all'', and any word may
be used in place of ``in''. The abbreviations ``oob'' and ``ooa'' may be used
in place of the keywords ``on_or_before'' and ``on_or_after'', respectively.
..PP
Wildcard day names are also provided. The keyword ``weekday'' applies to any
days which are normally printed in black on the calendar. The keyword
``workday'' is the same, but does not include any holidays. The keyword
``holiday'' includes only those days flagged as holidays. The keywords
``nonweekday'', ``nonworkday'', and ``nonholiday'' are also recognized as
negations of the above. See the
..B CAVEATS
below for important notes on using these keywords.
..PP
Ordinal day numbers may be used to specify dates, either relative to the
month or to the year. Either words or numeric abbreviations may be used for
``first'' through ``fifth''; higher numbers must be given using the
numeric equivalent (e.g. 100th). Negative ordinal numbers may even be used.
For example, ``\-2nd'' means ``next to last''.
..PP
``Odd'' and ``even'' do not refer to the actual date; instead, ``odd''
means ``alternate, starting with the first'', and ``even'' means ``alternate,
starting with the second''. Thus, ``odd Fridays in March'' refers to
the first, third, and (if present) fifth Fridays in March - not to
those Fridays falling on odd dates.
..PP
``All'' refers to each individual month; ``year'' refers to the year
as an entity. Thus ``odd Fridays in all'' refers to the first, third, and fifth
Friday of each month, while ``odd Fridays in year'' refers to
the first Friday of January and every other Friday thereafter.
..PP
Text in the date file may use C-like escape sequences (i.e. a `\\' followed by
a character, 1 \- 3 octal digits, or `x' followed by 1 \- 2 hexadecimal digits).
Escaped whitespace (including
..B newline
) and the standard ANSI character escapes (`\\a', `\\b', `\\f', `\\n', `\\r',
`\\t', `\\v') are all replaced by a single blank.
..PP
Lines in the
..I \.calendar
file consisting of
..B year ####
(where
..B ####
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
..B opt <options>
can be used to override the defaults for
any command-line options except
..BR \-e ,
..BR \-f ,
..BR \-h ,
..BR \-v ,
..BR \-D ", and"
..BR \-U .
Any options specified in this manner
are, in turn, overridden by those specified explicitly on the command line.
..PP
Lines in the
..I \.calendar
file consisting of
..B note <month>
can be used to place notes regarding the
entire month is one of the unused blocks of the calendar. The
..B <month>
indicator may be either a number 1 through 12 or an alphabetic month name
as described above; ``note all'' will place the associated text in the
notes block for each month in the current year.
..PP
Comments are supported in the
..I \.calendar
file. Any characters following a `#' character through the end of the
line are ignored.
..PP
..I Pcal
supports rudimentary
..IR cpp -like
functionality in the
date file, allowing the following constructs:
..BR "define | undef" ,
..B if{n}def ... {else ...} endif,
and
..BR include .
Note that these are not preceded by `#' as they are in C.
Symbol names defined using these keywords (or via the
..B -D
option) are case-insensitive.
It is not an error to
..BR undef
an undefined symbol, nor to
..BR define
a previously-defined one. An
..BR ifdef
alone is always
..BR false "; an"
..BR ifndef
alone is always
..BR true .
..PP
The name of the file in the
..BR 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
..B ~/
to the user's home directory.
..PP
In addition to pre-processing keywords,
..I pcal
also accepts boolean expressions in
..B if{n}def
directives. These expressions consist of symbol names joined by the boolean
operators
..BR ! ", " & ", " ^ ", and "
..BR | ,
in order of precedence, high to low. Parentheses may be used to alter the
precedence. The synonyms
..BR && " and " ||
are accepted for
..BR & " and " | .
A symbol name evaluates to
..B true
if currently defined,
..B false
if not; thus:
..PP
..ft CW
..nf
X ifdef A | B | C
..fi
..ft
..PP
\&...is
..B true
if any of the symbols A, B, and C is defined, and:
..PP
..ft CW
..nf
X ifdef A & B & C
..fi
..ft
..PP
\&...is
..B true
if they all are. Note that
..B ifndef <expr>
is equivalent to
..B ifdef !( <expr> ).
..PP
..B The Moon File
..PP
If a file of the name
..IR .moon## " (" moon##.dat
under MS-DOS),
where
..B ##
is the last two digits of the calendar year, exists in the same directory
as the date file,
..I pcal
uses the information contained within to calculate the phase of the
moon. If no such file exists,
..I pcal
uses an approximate algorithm.
..PP
Entries in the moon file must conform to the following syntax:
..PP
If the
..B \-A
option (American date formats, the default) is given:
..PP
..ft CW
..nf
X <quarter> <month><sep><day> {<hour><sep><min>}
..fi
..ft
..PP
If the
..B \-E
option (European date formats) is given:
..PP
..ft CW
..nf
X <quarter> <day><sep><month> {<hour><sep><min>}
..fi
..ft
..PP
Where:
..PP
..nf
X <quarter> := ``nm'', ``fq'' or ``1q'', ``fm'', ``3q'' or ``lq'' (new moon,
X first quarter, full moon, last quarter)
X <hour> := number 0-23 (24-hour clock)
X <min> := number 0-59
..fi
..PP
This file must contain entries for all quarter moons in the year,
in chronological order; if any errors are encountered,
..I pcal
will revert to using its default algorithm.
..PP
As in the date file, comments start with `#' and run through the
end of the given line.
..PP
..B Options
..PP
..I Pcal
has many options:
..P
..TP 12
..B \-e
Prints an empty calendar. Do not print entries from a
..I \.calendar
file.
..TP
..BI \-f " cal"
Directs
..I pcal
to use the file name
..I cal
as the input file in place of the default
..I \.calendar
file in the user's home directory (or the directory pointed to by
..BR PCAL_DIR ).
..TP
..BI \-o " file"
Directs
..I pcal
to write the output to
..I file
instead of to stdout.
..TP
..B \-l
Causes the output to be in landscape mode (default). This also resets the
x- and y-axis scaling and translation factors to the defaults for
landscape mode.
..TP
..B \-p
Causes the output to be in portrait mode. This also resets the
x- and y-axis scaling and translation factors to the defaults for portrait
mode.
..TP
..B \-j
Causes the Julian date (day of year) to be printed in each calendar box.
..TP
..B \-J
Causes the Julian date and the number of days remaining in the year to
be printed in each calendar box.
..TP
..B \-m
Causes moon icons to be printed on dates corresponding to
new, half, and full moons (the default is that no moons are printed).
..TP
..B \-M
Causes moon icons to be printed on all dates (the default is
that no moons are printed).
..TP
..BI \-b " day" " | all"
Causes all dates falling on weekday
..I day
to be printed in black;
..B \-b all
causes all weekdays to be printed in black.
..TP
..BI \-g " day" " | all"
Causes all dates falling on weekday
..I day
to be printed in gray;
..B \-g all
causes all weekdays to be printed in gray.
..IP
The default for the
..BR \-b " and " \-g
options is to print Saturdays and Sundays in gray and other days, unless
flagged as holidays, in black.
..TP
..BI \-O
Causes ``gray'' dates to be printed as outlined characters.
..TP
..BI \-G
Causes ``gray'' dates to be printed as outlined characters filled with gray.
..TP
..BI \-F " day"
Selects weekday
..I day
as the first day of the week. The given day will appear in the left-most
column of the calendar.
..TP
..B \-A
Directs
..I pcal
to use American date conventions
..B mm/dd{/yy}
and
..B month dd
) when parsing the date file (default).
..TP
..B \-E
Directs
..I pcal
to use European date conventions
..B dd/mm{/yy}
and
..B dd month
) when parsing the date file.
..TP
..BI \-X " xtrans"
Specifies the x-axis translation value for positioning the output on the page.
..TP
..BI \-Y " ytrans"
Specifies the y-axis translation value for positioning the output on the page.
..TP
..BI \-x " xscale"
Specifies the x-axis scaling factor for the calendar size.
..TP
..BI \-y " yscale"
Specifies the y-axis scaling factor for the calendar size.
..TP
..BI \-t " title_font"
Specifies the name of a font to use to print the
month name and year at the top of the calendar. For example,
..BR "pcal \-t Times-Roman" .
..TP
..BI \-d " day_font"
Similar to the
..B \-t
option, but selects the font used to print the day numbers.
..TP
..BI \-n " text_font"
Similar to the
..B \-t
option, but selects the font used to print the text inside each day and in
the notes block.
..TP
..BI \-D " symbol"
Defines the named symbol prior to reading the date file.
..TP
..BI \-U " symbol"
Un-defines the named symbol prior to reading the date file.
..TP
..BI \-L " string"
Causes the accompanying string to be printed as a left-justified footer.
Format specifiers denoting the month and/or year may appear in the string;
the appropriate values will be substituted upon printing.
..TP
..BI \-C " string"
Causes the accompanying string to be printed as a centered footer.
Format specifiers denoting the month and/or year may appear in the string;
the appropriate values will be substituted upon printing.
..TP
..BI \-R " string"
Causes the accompanying string to be printed as a right-justified footer.
Format specifiers denoting the month and/or year may appear in the string;
the appropriate values will be substituted upon printing.
..TP
..BI \-B
Causes
..I pcal
to leave unused calendar boxes blank (default is gray).
..TP
..BI \-w
Causes
..I pcal
to print a calendar for 12 consecutive months: 3 rows / 4
columns in landscape mode, 4 rows / 3 columns in portrait mode. See the
..B CAVEATS
section for details on the use of this option with other options.
..TP
..B \-I
Resets all parameters to the program defaults.
..TP
..B \-h
Causes
..I pcal
to write version information, usage message, and full explanation of options
and file formats (to
..IR stdout )
and terminate.
..TP
..B \-v
Causes
..I pcal
to write version information only (to
..IR stdout )
and terminate.
..PP
Any option which normally takes an argument may be specified without
the argument in order to reset the value to the program default. Note that
while the
..B \-D
option alone clears all the defined symbols, the
..B \-U
option alone has no effect. The
..B \-
(or
..BR "\-\|\-" " as per"
System V) argument may be used to disambiguate command lines such as:
..IP
..B pcal \-t 9 90
..PP
This could be written instead as one of the following:
..IP
..B pcal \-t \- 9 90
..br
..B pcal \-t \-\|\- 9 90
..PP
If the environment variable
..BR PCAL_OPTS
is defined, its contents are parsed as a command line. Flags set via
..BR PCAL_OPTS
override the program defaults, but are overridden by options set via
..B opt
lines in the
..I \.calendar
file or explicitly on the command line.
..SH CAVEATS
The ``workday'' and ``holiday'' keywords are aware of only those holidays
which have already been flagged at the point where they appear. For example,
consider January 1990:
..PP
..ft CW
..nf
..ne 7
X January 1990
X S M Tu W Th F S
X 1 2 3 4 5 6
X 7 8 9 10 11 12 13
X 14 15 16 17 18 19 20
X 21 22 23 24 25 26 27
X 28 29 30 31
..fi
..ft
..PP
If the
..I \.calendar
file looked like this:
..PP
..ft CW
..nf
X workday on_or_before all 15 payday
X 3rd Mon in Jan* MLK day
..fi
..ft
..PP
\&\.\.\. then
..I pcal
would mark the 15th as ``payday'' since at that point in the
..I \.calendar
file it has no way of knowing that January 15th will later be flagged as a
holiday. If the two lines were reversed, such that the holiday preceded the
``workday'' wildcard, then
..I pcal
would work as intended, marking instead the 12th as ``payday''. Also, beware
of year boundaries which affect the handling of all of the day wildcard
keywords. In general, it is best to place monthly wildcards such as the
example above at the end of each year to achieve the desired effect.
..PP
When the
..B \-w
and
..B \-p
options are used together,
..I pcal
revises the y-scale factor in order to use the entire portrait page; therefore,
the user should avoid using use the
..B \-y
option when using both the
..B \-w
and
..B \-p
options. Use of the
..B \-w
option in any case effectively disables the
..BR \-m ", " \-M ", " \-j ", and "
..B \-J
options.

%
% 4.1 modified by Andrew Rogers:
%
% support -G option (cf. prtday) to print "gray" dates as filled
% outlines
%
% 4.0 modified by Andrew Rogers:
%
% support -w ("whole year") option - cf. printmonth_[pl], startpage
% moved all the calendar calculations to pcal.c and moonphas.c (q.v.)
%
% support -B option (leave unused boxes blank)
%
% support -O option (print "gray" numbers as outlines)
%
% revised several of the basic routines and added some others; dates,
% moons, text, Julian days are now relative to upper-left corner of box
%
% enlarged title and dates in small calendars
%
% 3.0 modified by Andrew Rogers:
%
% added xsval, ysval, xtval, ytval for scaling and translation
% as per Ed Hand
%
% added day-of-year support (-j, -J flags)
%
% 2.6 * no modifications *
%
% 2.5 modified by Joe Brownlee:
%
% made day numbers smaller, providing more room for event text
% repositioned event text and moons accordingly
% added support for variable first day of week
%
% 2.4 * no modifications *
%
% 2.3 modified by Jamie Zawinski <jwz@lucid.com>:
%
% merged in moon routines (originally by Mark Hanson)
%
% 2.2 modified by Joe Brownlee:
%
% add "notetext" to print notes in unused calendar box
%
% 2.1 modified by Mark Kantrowitz:
%
% use symbolic names instead of magic numbers throughout
% support -L, -C, -R, -n options (all new)
% print holiday text in otherwise-wasted space next to date
% use larger text for dates in large calendars
%
% 2.0 modified by Andrew W. Rogers:
%
% skip printing days of week on small calendars
% center month and year at top of calendar
% use correct algorithm for leap year calculation
% get month and day names from main program
% use table to determine color (black/gray) of weekdays and holidays
% use hanging indent to print continued text lines
