<h2>DESCRIPTION</h2>
<p style="margin-left:11%; margin-top: 1em"><i>Pcal</i>
generates PostScript to produce landscape or portrait
calendars for any month and year. The arguments
<b>month</b>, <b>year</b>, and <b>nmonths</b>, if provided,
should be numeric. The <b>month</b> value should be in the
range 1 − 12, and the <b>year</b> value should be
specified as 1 or 2 digits (in which case it will be
interpreted as that year in the current century) or as the
full 4-digit year. If no numeric arguments are provided, the
calendar for the current month and year will be
generated.</p>
<p style="margin-left:11%; margin-top: 1em">If one numeric
argument is provided, it is interpreted as the <b>year</b>
value, and calendars for the entire year will be generated.
Otherwise, <b>nmonths</b> months, starting with <b>month</b>
and <b>year</b>, will be generated.</p>
<p style="margin-left:11%; margin-top: 1em">For whole-year
calendars (i.e. when the <b>−w</b> 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</b> argument
alone is given, it is expected to be the desired <b>year</b>
to print, and prints all of the months in the given year. If
both <b>month</b> and <b>year</b> are given, then 12
consecutive months are printed starting at the given month
and year. If the <b>month</b>, <b>year</b>, and
<b>nmonths</b> arguments are all present, printing begins
with the given month and year and <b>nmonths</b> months are
printed, rounded up to the nearest multiple of 12.</p>
<p style="margin-left:11%; margin-top: 1em"><b>The Date
File (Configuration File)</b> <br>
By default, <i>pcal</i> simply prints an empty calendar. Its
real power is in its ability to place
‘‘events’’ (and, for monthly-format
PostScript calendars, Encapsulated PostScript images [e.g.
photos and icons]) in appropriate days on the (PostScript or
HTML) calendar, thus allowing the user to create
personalized calendars. This is achieved through the use of
the ‘‘date file’’, also known as the
‘‘configuration file’’.</p>
<p style="margin-left:11%; margin-top: 1em">The default
date/configuration file is expected to be named
<i>.calendar</i> (<i>pcal.dat</i> under MS-DOS), or
<i>calendar</i> for compatibility with older versions.
<i>Pcal</i> will look in several places for such a file.
First, if the environment variable <b>PCAL_DIR</b> is
defined, <i>pcal</i> searches the directory indicated by
that variable. Next, <i>pcal</i> searches the user’s
home directory (as specified by the <b>HOME</b> environment
variable). If neither <b>PCAL_DIR</b> nor <b>HOME</b> is
defined, <i>pcal</i> searches the current directory instead.
Finally, if enabled (via the ‘SEARCH_PCAL_DIR’
flag) when <i>pcal</i> was built, the directory where the
<i>pcal</i> executable resides will be checked. If no date
file is found, an empty calendar is printed; no error is
generated.</p>
<p style="margin-left:11%; margin-top: 1em">Alternatively,
the name of the date file (and, optionally, the path where
it can be found) can be specified using the <b>−f</b>
command-line option. See the <b>OPTIONS</b> section for more
details.</p>
<p style="margin-left:11%; margin-top: 1em">Every
<i>pcal</i> distribution comes with an
’examples’ directory. The
‘pcal-cfg.txt’ file that is located there
contains a myriad of examples of settings that can be used
in your own configuration file. Please check it out for lots
of useful ideas. Furthermore, that directory contains
several language/country-specific examples (including
holiday and other event definitions) in various
‘calendar_xx.txt’ files, where ‘xx’
represents the 2-letter language code (e.g.
’calendar_de.txt’ is the German example
file).</p>
<p style="margin-left:11%; margin-top: 1em">If a date file
is found, it will be searched for lines with leading dates
matching the requested month and year.</p>
<p style="margin-left:11%; margin-top: 1em">Any text
following the dates found will be printed on the calendar
under the appropriate day of the month. Encapsulated
PostScript (EPS) images are handled similarly as described
in a later subsection.</p>
<p style="margin-left:11%; margin-top: 1em"><b>troff</b>-style
escape sequences \fB, \fI, \fP, and \fR may be used to set
the font style to Bold, Italic, the previous font style, or
Roman respectively. For those more familiar with HTML,
<B>, <I>, </B>, and </I> may be used
instead to enable/disable Bold or Italic font styles. The
font style is reset to Roman after each line break.</p>
<p style="margin-left:11%; margin-top: 1em">Using the
‘include’ pre-processor directive (described in
the section entitled ‘Pre-Processor
Functionality’, below), other configuration files can
be processed from within an existing configuration file.
That is, you can ‘nest’ configuration files as
needed.</p>
<p style="margin-left:11%; margin-top: 1em">Dates
(essentially ‘events’) in the configuration
files may be expressed in any of several formats:</p>

month name whose first 3 letters are the same as the first 3
letters of one of the names of the days of the week. Because
of this, the specification in such a language of any month

<p style="margin-left:11%; margin-top: 1em">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 numerics to be printed in the color specified by
the <b>−s</b> option (default = gray) and will cause
the associated text (on monthly-format calendars) to be
placed adjacent to the numeric date in the day box rather
than below the numeric date (as is done for all non-holiday
events). ‘‘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.
‘‘Nearest’’ attempts to match the
specified date; if that fails, it tries the day after, then
the day before, then two days after, two days before, and so
forth until a match occurs.</p>
<p style="margin-left:11%; margin-top: 1em">Wildcard day
names are also provided. The keyword
‘‘weekday’’ applies to any days
which are normally printed in "logical black" -
the predominant day color - 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</b> below for
important notes on using these keywords. Moon phases may
also appear as wildcards; ‘‘nm’’ is
accepted as a synonym for
‘‘new_moon’’,
‘‘1q’’ and
‘‘fq’’ for
‘‘first_quarter’’,
‘‘fm’’ for
‘‘full_moon’’,
‘‘3q’’ for
‘‘third_quarter’’, and
‘‘lq’’ for
‘‘last_quarter’’.</p>
<p style="margin-left:11%; margin-top: 1em">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’’.</p>
<p style="margin-left:11%; margin-top: 1em">‘‘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.</p>
<p style="margin-left:11%; margin-top: 1em">‘‘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.</p>
<p style="margin-left:11%; margin-top: 1em">‘‘Nearest’’,
‘‘nearest_before’’, and
‘‘nearest_after’’ refer to the
nearest weekday or wildcard day with respect to the
specified date. ‘‘Nearest_before’’
and ‘‘nearest_after’’ allow the user
to specify how <i>pcal</i> is to disambiguate between two
dates that are equally near: e.g., ‘‘nonweekday
nearest_before [Wed.] 9/25/96’’ refers to
Sunday, 9/22 while ‘‘nonweekday nearest_after
9/25/96’’ refers to Saturday, 9/28. (Note that
‘‘nearest_before’’ and
‘‘nearest_after’’ are equivalent to
‘‘nearest’’ when no such ambiguity
exists: e.g., ‘‘nonweekday nearest_before [Thu.]
9/26/96’’ refers to Saturday, 9/28.)</p>
<p style="margin-left:11%; margin-top: 1em">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</b> ) and the standard ANSI character escapes
(‘\a’, ‘\b’, ‘\f’,
‘\n’, ‘\r’, ‘\t’,
‘\v’) are all replaced by a single blank.</p>
<p style="margin-left:11%; margin-top: 1em">The HTML
special characters ‘&lt;’
‘&gt;’ ‘&quot;’
‘&amp;’ ‘&nbsp;’ and
‘&#NNN;’ (NNN = any three decimal digits)
are also supported. These will be propagated intact (be sure
to escape the ‘#’ in ‘&#NNN;’)
if the output is specified as HTML (see the <b>−H</b>
flag); otherwise they will be converted to their ASCII
equivalents. This allows a common date file to be used
regardless of whether the desired output format is HTML,
PostScript, or Un*x <i>calendar(1)</i> (see the
<b>−c</b> flag) input.</p>
<p style="margin-left:11%; margin-top: 1em">Lines in the
configuration file consisting of <b>year ####</b> (where
<b>####</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.</p>
<p style="margin-left:11%; margin-top: 1em">Lines in the
configuration file consisting of <b>year all</b> (or,
alternatively, <b>year *</b>) direct <i>pcal</i> to wildcard
following entries against every applicable year. This
assumes that the following entries do not contain a year;
any date entries containing year information (or an explicit
<b>year ####</b> entry) will set the remembered year to that
year.</p>
<p style="margin-left:11%; margin-top: 1em">Lines in the
configuration file consisting of <b>opt <options></b>
can be used to override the defaults for any command-line
options except <b>−c</b>, <b>−e</b>,
<b>−f</b>, <b>−h</b>, <b>−H</b>,
<b>−u</b>, <b>−v</b>, <b>−D</b>, and
<b>−U</b>. Any options specified in this manner are,
in turn, overridden by those specified explicitly on the
command line.</p>
<p style="margin-left:11%; margin-top: 1em">Lines in the
configuration file consisting of <b>note{/<number>}
<month></b> can be used to place notes regarding the
entire month in one of the unused blocks of the calendar.
The <b><month></b> 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. <b><number></b> is an optional positive
or negative number specifying the empty box where the
associated text is to be placed. If positive, <i>pcal</i>
counts forward from the first empty box; if negative,
<i>pcal</i> counts backward from the last empty box. Thus,
<b>‘‘note/1’’</b> places the
associated text in the first empty box; <b>note/-3</b> in
the third-to-last. The default is -1 if no <number> is
given (last empty box, immediately preceding the small
calendars on the bottom row; cf. <b>−S</b>,
<b>−k</b>, and <b>−K</b>, below). You can place
several notes in the same box. You can also use more than 1
box for the various monthly notes.</p>
<p style="margin-left:11%; margin-top: 1em">Lines in the
configuration file consisting of <b>input-language XX</b>
(where <b>XX</b> is the 2-letter specification for any of
the supported languages) can be used to set the language
used for interpretation of the month names and day-of-week
names for the remaining event entries. This option may be
specified more than once, as needed, if the language used to
describe events changes within the file. For backwards
compatibility, the default value for ‘input
language’ if this directive is never used is
’en’ (English). Note that this directive is
distinct from the specification of ’output
language’ as accomplished with the <b>−a</b>
option.</p>
<p style="margin-left:11%; margin-top: 1em">Comments are
supported in the configuration file. Any characters
following a ‘#’ character are ignored, through
the end of that line, unless the ‘#’ character
is escaped by ‘\’.</p>
<p style="margin-left:11%; margin-top: 1em"><b>Deleting
Events</b> <br>
By prepending the <i>‘delete’</i> keyword to an
event specification, one or more events may be deleted from
a set of previously-specified events.</p>
<p style="margin-left:11%; margin-top: 1em">For example,
the following lines might appear in the date file:</p>
<p style="margin-left:22%; margin-top: 1em">all Friday in
all Poker game <br>
delete first Friday in all Poker game</p>
<p style="margin-left:11%; margin-top: 1em">This results in
an event labeled ‘Poker game’ on every Friday
except the first Friday of the month. If you delete an entry
which is marked as a holiday, the ‘holiday’ flag
for that day will be recalculated. Any ‘delete’
entries which don’t match any pre-existing entries are
silently ignored.</p>
<p style="margin-left:11%; margin-top: 1em"><b>Format
Specifiers</b> <i><br>
Pcal</i> allows format specifiers in both the event text and
footer strings (see the <b>−L</b>, <b>−C</b>,
<b>−R</b>, and <b>−N</b> options below). Each
format specifier will be replaced by a corresponding string
as outlined in the following table:</p>

<p style="margin-left:11%; margin-top: 1em">Most of these
are derived from the ANSI C <tt>strftime()</tt> function,
but the <b>%[louwMD]</b> and <b>%[o0+−]</b> format
specifiers are specific to <i>pcal</i>.</p>
<p style="margin-left:11%; margin-top: 1em">The <b>%u</b>
specifier considers the week containing 1/1 (Jan 1st) as
week 1 and the following logical Sunday (the first day of
the week as printed; cf. the <b>−F</b> option below)
as the start of week 2; <b>%U</b> considers the first
logical Sunday as the first day of week 1. <b>%w</b> and
<b>%W</b> behave like <b>%u</b> and <b>%U</b> respectively,
but use the first logical Monday instead. Note that
<b>%w</b> has a different meaning from
<tt>strftime().</tt></p>
<p style="margin-left:11%; margin-top: 1em">The <b>%o</b>
format specifier prints a number as an ordinal, with the
appropriate suffix (‘‘st’’,
‘‘nd’’,
‘‘rd’’, or
‘‘th’’ in English) appended. For
example, <b>%od</b> prints the day of the month as
‘‘1st’’,
‘‘2nd’’,
‘‘3rd’’, etc.</p>
<p style="margin-left:11%; margin-top: 1em">Unlike
<tt>strftime(),</tt> <i>pcal</i> defaults to printing
numbers (except <b>%y</b>) without leading zeroes. If
leading zeroes are desired, the ‘0’ prefix may
be used. For example, <b>%0j</b> prints the first day of
year as ‘‘001’’.</p>
<p style="margin-left:11%; margin-top: 1em">The <b>%+</b>
and <b>%−</b> format specifiers direct <i>pcal</i> to
substitute the following/previous month/year in the
following <b>[bBmyY]</b> specifier. For example, <b>%+B</b>
prints the name of the next month.</p>
<p style="margin-left:11%; margin-top: 1em">The
<b>%{[+−]N}[DWMY]</b> format specifiers do not print
anything, but instead adjust the working date by ±
<b>N</b>days (<b>D</b>), weeks (<b>W</b>), months
(<b>M</b>), or years (<b>Y</b>). Subsequent format
specifiers use the adjusted date instead of the current
date. For example, <b>%+1M %B %Y</b> adjusts the date
forward by one month and then prints the resulting month and
year (‘‘January 1992’’ in December,
1991); <b>%−2W %b %d</b> adjusts the date backward by
two weeks and prints the resulting month and day
(‘‘Jul 26’’ on August 9).</p>
<p style="margin-left:11%; margin-top: 1em">Such date
adjustments are normally cumulative; for example,
<b>%+1Y%−1D</b> adjusts the date forward by one year
and then backward by one day. If <b>%D</b> or <b>%M</b> is
specified alone (or if <b>N</b> is zero), <i>pcal</i>
restores the original date. Note that <b>%M</b> has a
different meaning to the <tt>strftime()</tt> function.</p>
<p style="margin-left:11%; margin-top: 1em">Here’s a
common, useful example of an event entry for the <i>pcal</i>
date file which combines the ability to adjust working dates
and the ability to display ordinals. This particular example
is used to display text on the birthday of a person born in
1991:</p>
<p style="margin-left:22%; margin-top: 1em">May 10
Eric’s %-1991Y%oY Birthday</p>
<p style="margin-left:11%; margin-top: 1em">That entry
would result in the following text being displayed on May
10, 2005:</p>
<p style="margin-left:22%; margin-top: 1em">Eric’s
14th Birthday</p>
<p style="margin-left:11%; margin-top: 1em"><b>Encapsulated
PostScript (EPS) Images</b> <br>
For monthly PostScript calendars only, <i>pcal</i> supports
the embedding of one or more EPS images (photos, icons, etc)
into any given day of the month. (EPS image specifications
in the <i>pcal</i> date file are ignored for yearly
PostScript calendars and for all HTML calendars.)</p>
<p style="margin-left:11%; margin-top: 1em">In order to
associate an image with a given event, you must add one or
more entries to the date file. The event date is specified
exactly as described previously for simple event text
specification lines. However, instead of specifying the text
associated with the event, you instead specify the EPS image
filename and some additional parameters in the following
format:</p>
<pre style="margin-left:11%; margin-top: 1em"> image:<EPS-image-filename> <x-scale> <y-scale> <x-delta> <y-delta></pre>

horizontal dimension. Generally speaking, only positive
values should be used. However, in the rare case that you
find that your EPS image needs to be flipped about the
vertical axis (i.e. left to right), you can use a negative
value to achieve this without having to tweak the actual

<p style="margin-left:11%; margin-top: 1em">Here’s an

<p style="margin-left:11%; margin-top: 1em">You can place
as many images as you want on a single day of the month by
specifying repeated lines in the date file. For example,
these lines put icons of George Washington and Abraham
Lincoln on the day of the U.S.
‘‘Presidents’ Day’’ holiday,
along with the event text:</p>
<pre style="margin-left:11%; margin-top: 1em"> 3rd Monday in Feb* Presidents’ Day
3rd Monday in Feb* image:/eps-path/washington.eps 0.08 0.08 8 0

<p style="margin-left:11%; margin-top: 1em">Note that the
icon for Lincoln is shifted to the right by 48 typographic
points so as not to overlay the first icon.</p>
<p style="margin-left:11%; margin-top: 1em">The <i>pcal</i>
releases come with a single EPS sample file
(’eps/recycle.eps’) of the ubiquitous
’recycle’ icon (3 green arrows in a triangular
shape). Such an image might be used with configuration file
settings like this:</p>
<pre style="margin-left:11%; margin-top: 1em"> second Sat in all RECYCLE!
second Sat in all image:/eps-path/recycle.eps 0.039 0.039 34 -9</pre>
<p style="margin-left:11%; margin-top: 1em">In cases where
you’re displaying non-holiday event text (e.g.
someone’s birthday) and an EPS image, you’ll
often need to use a negative ‘Y-delta’ value on
the EPS image specification line, in order to shift the
image down so that it doesn’t cover the event text,
which appears just below the day’s numerics for
non-holiday events. (Text for holiday events appears higher
up, to the right of the day’s numerics, so
there’s usually no collision with the EPS image.)</p>
<p style="margin-left:11%; margin-top: 1em"><b>Note:</b>
Unfortunately, most EPS images cannot be used directly by
<i>pcal</i>.</p>
<p style="margin-left:22%; margin-top: 1em">Depending on
the EPS image used and how it was created, you may have to
remove or comment out some or all of the PostScript
‘translate’ commands, in order to avoid the use
of illogical X-delta and Y-delta values when specifying the
EPS image in your <i>pcal</i> date file. Most programs that
generate EPS output (either directly or via conversion from
some other graphic format) seem to have these
‘translate’ commands relatively early in the EPS
file.</p>
<p style="margin-left:22%; margin-top: 1em">It may take
some experimentation to get it just right. Preview the
<i>pcal</i> output using a PostScript viewer as you tweak
the PostScript commands in the EPS image file and/or the
event entry in the <i>pcal</i> date file.</p>
<p style="margin-left:32%; margin-top: 1em"><b>Note:</b>
Depending upon what application you use to preview
PostScript content, the monthly calendars may not show any

<p style="margin-left:11%; margin-top: 1em">For converting
non-EPS images (e.g. photos) to EPS format, one can use the
graphical GNU Image Manipulation Program, a.k.a. ‘The

<p style="margin-left:22%; margin-top: 1em"><i>http://www.gimp.org</i></p>
<p style="margin-left:11%; margin-top: 1em">For
icons/images in WMF format (which are popular in various
3rd-party, legacy-OS, commercial calendar programs), the
‘libwmf’/‘wmf2eps’ library/utility
is useful for generating <i>pcal</i>-capable EPS images. It
can be found at this site:</p>
<p style="margin-left:22%; margin-top: 1em"><i>http://wvware.sourceforge.net/libwmf.html</i></p>
<p style="margin-left:11%; margin-top: 1em">For
icons/images in SVG format, the ImageMagick
‘convert’ utility is sometimes useful for
generating <i>pcal</i>-capable EPS images. This suite of
utilities (which includes other useful ImageMagick utilities
like ‘display’ and ‘identify’) may
already be available on your Linux distribution. If not, it
can be found at this site:</p>
<p style="margin-left:22%; margin-top: 1em"><i>http://www.imagemagick.org</i></p>
<p style="margin-left:11%; margin-top: 1em">For cases where
ImageMagick’s ‘convert’ utility fails to
properly convert SVG-format images to EPS format, you can
try the method of converting the SVG image into an
intermediate format (e.g. PNG) using the ‘rsvg’
utility. This utility may already be available on your Linux
distribution. If not, it can be found at this site:</p>
<p style="margin-left:22%; margin-top: 1em"><i>http://librsvg.sourceforge.net/</i></p>

<p style="margin-left:11%; margin-top: 1em"><b>Note:</b>
The EPS image content is not generated in the PostScript
output -- only a reference to the EPS image filename is
generated. From a practical standpoint, this means that
normally you’ll need to print/preview the PostScript
output of <i>pcal</i> from the same computer/setup as that
which was used to run <i>pcal</i> in the first place. If you
want to generate a calendar with embedded EPS images that
will later be printed/viewed on another machine which does
not have access to those EPS images, you’ll need to
run the output through a pre-processor which will put the
EPS image content into the PostScript output file. For
example, assuming your initial calendar output was generated
to a file named ‘pcal.ps’, on most GNU/Linux
systems you could run this command, which uses the popular
‘Ghostscript’ interpreter:</p>
<p style="margin-left:22%; margin-top: 1em">gs -r300x300
-dBATCH -dNOPAUSE -sDEVICE=pswrite -sOutputFile=out.ps
pcal.ps</p>
<p style="margin-left:11%; margin-top: 1em">This would
generate a PostScript file named ‘out.ps’, at
300x300 dpi resolution, which has the actual EPS image
content embedded within, allowing you to transport the
‘out.ps’ file to another computer for
viewing/printing. Of course, the new file is substantially
larger, but it’s portable. Furthermore, the EPS images
will be viewable even in PostScript-viewing applications
(see above) which don’t properly support the display
of embedded (by filename only) EPS images.</p>
<p style="margin-left:11%; margin-top: 1em"><b>Pre-Processor

undefined symbol, nor to <b>define</b> a previously-defined
one.</p>
<p style="margin-left:11%; margin-top: 1em">A symbol can be
defined with just a name (e.g. ‘‘define
MY_SYM’’) or it can take on a value (e.g.
‘‘define MY_SYM SOME_VALUE’’). Use
of symbol values is convenient for defining a starting date
then using that symbol to reference that starting date in
one or more events. For example, these definitions in the
date file might be useful:</p>
<pre style="margin-left:11%; margin-top: 1em"> define semester_start 8/23 # Beginning of semester
semester_start Class Start
7th day after semester_start 1st Quiz
14th day after semester_start 2nd Quiz
undef semester_start</pre>
<p style="margin-left:11%; margin-top: 1em">Be aware that
the substitution of symbol values for symbol names is not
robust, so it’s wise to use a symbol name that’s
unlikely to occur in any of your other event text. In other
words, if you defined the ‘semester_start’
symbol in the example above as merely ‘start’,
then you’d get the undesired effect of having the text
‘Class 8/23’ in your calendar on that day
instead of ‘Class Start’! The use of
‘undef semester_start’ in the above example is
optional and is really only useful to prevent any unwanted
symbol substitutions later on, which probably won’t
happen unless you poorly choose your symbol name to begin
with.</p>
<p style="margin-left:11%; margin-top: 1em">An <b>ifdef</b>

<i>Pcal</i> is smart enough to translate <b>~/</b> to the

<p style="margin-left:11%; margin-top: 1em"><i>Pcal</i>
normally terminates immediately if the file specified in an
<b>include</b> directive does not exist. An alternate form
of the directive, <b>include?</b>, directs <i>pcal</i> to
continue silently if the file does not exist or cannot be
opened.</p>
<p style="margin-left:11%; margin-top: 1em">In addition to
pre-processing keywords, <i>pcal</i> also accepts boolean
expressions in <b>if{{n}def}</b> and <b>elif</b> directives.
These expressions consist of symbol names joined by the

may be used to alter the precedence. The synonyms
<b>&&</b> and <b>||</b> are accepted for

<p style="margin-left:11%; margin-top: 1em"><b>Generating
PostScript Calendars Via A Web Browser Interface</b> <br>
PostScript-format <i>pcal</i> calendars can be generated and
viewed from a web browser interface.</p>
<p style="margin-left:22%; margin-top: 1em"><b>Note:</b>
This is not to be confused with the ability to generate
non-PostScript, HTML-format (using the <b>−H</b>
command-line option) calendars, which is a different
capability entirely.</p>
<p style="margin-left:11%; margin-top: 1em"><i>Pcal</i>
comes with 4 files that provide this ability:
‘pcal.cgi’ (a Bourne shell script),
‘pcal.pl’ (a Perl equivalent of
‘pcal.cgi’), ‘pcal.html’, and
‘pcalw.html’.</p>
<p style="margin-left:11%; margin-top: 1em">The CGI file
(either ‘pcal.cgi’ or ‘pcal.pl’)
must be edited before using it. Change the definition for
<i>‘pcal=’</i> (Bourne shell script) or
<i>‘my $PCAL =’</i> (Perl script) to point to
the location of the <i>pcal</i> executable file. Change the
definition for <i>‘file=’</i> (Bourne shell
script) or <i>‘my $FILE =’</i> (Perl script) to
point to the location of the <i>pcal</i> ‘date
file’ (e.g. ‘.calendar’), which contains
the options for running <i>pcal</i>. Finally, copy the
‘pcal.cgi’ (or ‘pcal.pl’) file to
the location where your web server expects to find such
files (e.g. ‘/var/www/cgi-bin/’).</p>
<p style="margin-left:11%; margin-top: 1em">The
‘pcal.html’ and ‘pcalw.html’ files
must also be edited. Each one has a line like this:</p>
<p style="margin-left:22%; margin-top: 1em"><FORM
ACTION="http://yourpath/cgi-bin/pcal.cgi"
METHOD=GET></p>
<p style="margin-left:11%; margin-top: 1em">That line must
be edited to point to the host and location of your CGI
script file (‘pcal.cgi’ or
‘pcal.pl’).</p>
<p style="margin-left:11%; margin-top: 1em">Once
that’s done, point your web browser to the
‘pcal.html’ or ‘pcalw.html’ file to
generate monthly/yearly PostScript calendars for viewing
within your web browser.</p>
<p style="margin-left:22%; margin-top: 1em"><b>Note:</b>
Depending upon what application your web browser spawns to
preview PostScript content, the monthly calendars generated
via this web browser interface may not show any embedded EPS
images. For a rundown of some popular PostScript-viewing
applications and whether they correctly display the embedded
EPS images, see the section (above) entitled
‘Encapsulated PostScript (EPS) Images’.</p>

details on specifying the ‘input language’.</p>
<p style="margin-left:22%; margin-top: 1em"><b>Note:</b> In
order to display diacritical marks, languages other than
English require that the characters be remapped. Normally,
no action is required since <i>pcal</i> automatically
selects a remapping which is appropriate to the selected
language. However, if you want to override the default
remapping for a given language, you would use the
<b>−r</b> option (e.g. "-r Latin1").</p>
<p style="margin-left:22%; margin-top: 1em">Furthermore, an
appropriate font should be selected as needed using the
<b>−t</b> option (e.g. "-t
some-latin1-font-name"). Any language using the
"Latin1" remapping (e.g. French, German, Italian,
Spanish, etc) requires an ISO 8859-1 (’Latin1’)
font. The Greek language requires an ISO 8859-7 (similar to
ELOT-928) font (available from Angelo Haritsis
<ah@doc.ic.ac.uk>; also see
http://www.hellenic.net/fonts/). Similarly, Russian requires
a KOI8-R font while Ukrainian requires a KOI8-U font.</p>
<p style="margin-left:22%; margin-top: 1em"><i>Pcal</i>
predefines the symbol <b>lang_XX</b>, where <b>XX</b> is the
two-character abbreviation for the selected output

automatically select an appropriate default character
encoding (mapping) for the language for which the calendar
is being generated.</p>
<p style="margin-left:22%; margin-top: 1em">The value
specified for <i>mapping</i> is case-insensitive and may be

<h2>AUTHORS</h2>
<p style="margin-left:11%; margin-top: 1em">The original
PostScript code to generate the calendars was written by
Patrick Wood (Copyright © 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 King Ables, Tim Tessin, Joe
Wood, Jeff Mogul, Mark Hanson, and 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, Andrew Rogers, Mark Kantrowitz,
Joe Brownlee, Andy Fyfe, Steve Grandi, Geoff Kuenning,
Stefan Fronzek (1-column HTML output), Bill Bogstad (event
deletion capability), and Bill Marr (embedded EPS images,
command-line paper size specification, new paper sizes
[legal & tabloid], additional character mappings for new
languages, and various cleanups). The moon routines were
originally written by Jef Poskanzer and Craig Leres, and
were incorporated into <i>pcal</i> by Richard Dyson.
International language support was initially added by Angelo
Haritsis. Additional languages were added by Andrew Rogers
(Esperanto), Lars Wirzenius (Finnish), Pedro Zorzenon Neto
(Portuguese), Joel Fredrikson (Swedish), Volodymyr M.
Lisivka (Ukrainian), Neeme Praks (Estonian, Russian,
Latvian, Lithuanian), Peter Cernoch (Czech), Ferenc
Kruzslicz (Hungarian), Carles Sadurní Anguita
(Catalan), Dominik ’Chiron’ Derlatka (Polish),
Ewald Beekman (Dutch), Claudiu Costin (Romanian), Kenneth
Geisshirt (Danish), Zdenko Podobny (Slovak), and Eric
Nichols (Hawaiian).</p>
