# rem2html -- convert the output of "remind -pp" or "remind -ppp" to HTML
=head1 NAME
rem2html - Convert the output of "remind -pp" or "remind -ppp" to HTML
=head1 SYNOPSIS
remind -ppp [remind_options] file | rem2html [options]
remind -pp [remind_options] file | rem2html [options]
You can also use the old interchange format as below, but the -pp
or -ppp versions are preferred.
remind -p [remind_options] file | rem2html [options]
=head1 OPTIONS
=over 4
=item --help, -h
Print usage information
=item --version
Print version
=item --utf8
Assume standard input is encoded in UTF-8; write UTF-8 data to standard
output.
=item --backurl I<url>
When producing the small calendar for the previous month, make the
month name a link to I<url>.
=item --forwurl I<url>
When producing the small calendar for the next month, make the
month name a link to I<url>.
=item --imgbase I<url>
When creating URLs for the stylesheet or external images, use I<url>
as the base URL.
=item --pngs
Normally, rem2html uses inline "data:" URLs for the moon phase images,
yielding a standalone HTML file. The C<--pngs> option makes it use
external images named firstquarter.png, fullmoon.png, lastquarter.png
and newmoon.png, which are expected to live in C<--imgbase>.
=item --stylesheet I<url.css>
Use I<url.css> as the stylesheet. If this option is used,
I<url.css> is interpreted relative to B<imgbase> I<unless> it starts
with a "/".
=item --nostyle
Produce basic HTML that does not use a CSS stylesheet.
=item --tableonly
Output results as a E<lt>tableE<gt> ... E<lt>/tableE<gt> sequence only
without any E<lt>htmlE<gt> or E<lt>bodyE<gt> tags.
=item --title I<title>
Use I<title> as the content between E<lt>titleE<gt> and E<lt>/titleE<gt>
tags.
=item --yaag
Instead of making 7-column tables for each month, show each month
as a I<single> table row of 38 columns. This is the so-called
"year-at-a-glance" format. You must use the "-ppp" option to
C<remind> or the --yaag option will be ignored. And this format
works best if you create a calendar for an entire year (so, starting
in January and using "-ppp12" to get 12 months' worth of reminders.)
=item --prologue I<html_text>
Insert I<html_text> right after the E<lt>bodyE<gt> tag.
=item --epilogue I<html_text>
Insert I<html_text> right before the E<lt>/bodyE<gt> tag.
=back
=head1 SPECIALS SUPPORTED
The rem2html back-end supports the following SPECIAL reminders:
=over
=item HTML
Add an HTML reminder to the calendar. All HTML tags are available.
=item HTMLCLASS
Add a CSS class to the box representing the trigger date. See
"HIGHLIGHTING TODAY" for an example
=item WEEK, MOON, SHADE, COLOR
The standard SPECIALs supported by all back-ends
=back
=head1 INFO STRINGS SUPPORTED
Rem2html supports one INFO string, namely C<Url>. Its value
should be a URL. If the C<Url> INFO string is supplied for
a normal reminder, a COLOR special, a MOON special or a WEEK
special, the corresponding output is turned into a hyperlink.
=head1 HIGHLIGHTING TODAY
Older versions of rem2html used to highlight today's date with a red outline.
The current version does not do that by default. If you wish to highlight
today's date, add the following reminder to your reminders file:
REM [realtoday()] SPECIAL HTMLCLASS rem-today
=head1 AUTHOR
rem2html was written by Dianne Skoll with much inspiration from an
earlier version by Don Schwarz.
