calendar - Add links for the current month's, current year's, and older archived postings
|
||||
|

|
||||
|
||||
=head1 SYNOPSIS
|
||||
|
||||
To invoke the calendar, just use the preprocessor directive (options
|
||||
and variations are detailed below):
|
||||
|
||||
[[calendar ]]
|
||||
|
||||
or
|
||||
|
||||
[[calendar type="month" pages="blog/* and !*/Discussion"]]
|
||||
|
||||
or
|
||||
|
||||
[[calendar type="year" year="2005" pages="blog/* and !*/Discussion"]]
|
||||
|
||||
=cut
|
||||
|
||||
|
||||
=head1 DESCRIPTION
|
||||
|
||||
This plugin is inspired by the calendar plugin for Blosxom, but
|
||||
derives no code from it. This plugin is essentially a fancy front end
|
||||
to archives of previous pages, usually used for blogs. It can produce
|
||||
a calendar for a given month, or a list of months for a given year.
|
||||
|
||||
The year and month entities in the out put have links to archive index
|
||||
pages, which are supposed to exist already. The idea is to create an
|
||||
archives hierarchy, rooted in the subdirectory specified in the
|
||||
site wide customization variable, I<archivebase>. I<archivebase>
|
||||
defaults to C<archives>. Links are created to pages
|
||||
C<$archivebase/$year> and C<$archivebase/$year/$month>. If one creates
|
||||
annual and monthly indices, for example, by using something like this
|
||||
sample from my I<archives/2006/01.mdwn> (warning: line split for
|
||||
readability):
|
||||
|
||||
\[[meta title="Archives for 2006/01"]]
|
||||
\[[inline rootpage="blog" atom="no" rss="no" show="0"
|
||||
pages="blog/* and !*/Discussion and creation_year(2006)
|
||||
and creation_month(01)"
|
||||
]]

||||
|
||||
=item B<type>

|
||||
|
||||
=item B<pages>
|
||||
|
||||
Specifies the C<pagespec> used to get pages to match for

|
||||
Defaults to C<*>.

||||
=item B<week_start_day>
|
||||
|
||||
A number, in the range 0..6, which represents the day of the week that

||||

on. Defaults to 0, which is Sunday.

|
||||
respectively (today).
|
||||
|
||||

=head1 CAVEATS
|
||||
|
||||
In the month calendar, for days in which there is more than one
|
||||
posting, the link created randomly selects one of them. Since there is
|
||||
no easy way in B<IkiWiki> to automatically generate index pages, and
|
||||
pregenerating daily index pages seems too much of an overhead, we have
|
||||
to live with this. All postings can still be viewed in the monthly or
|
||||
annual indices, of course. This can be an issue for very prolific
|
||||
scriveners.

|
||||
|
||||
=head1 BUGS
|
||||
|
||||
Since B<IkiWiki> eval's the configuration file, the values have to all
|
||||
on a single physical line. This is the reason we need to use strings
|
||||
and eval, instead of just passing in real anonymous sub references,
|
||||
since the eval pass converts the coderef into a string of the form
|
||||
"(CODE 12de345657)" which can't be dereferenced.

No, you did not. But I am back to hacking on this, and I think I have discovered a major problem with my approach. One of the problems with the current plugin is that the goal of a calendar is to create a calendar, either a month or year based on, that provides links to blogs for all the days in (for the month calendar), and all the months (in a year calendar) in which there have been blog postings. For the monthly calendar, it needs to know the previous and next months where there is a posting, and for the year calendar, it needs to know which of the previous (next) years had entries.

Now, this means that it needs to know about at _all_ pages that meet the pagespec, and stash that information, before it begins generating the calandar in question, in order to calculate how to create the symlinks. And, of course, all pages that have calendars on them might need to change anytime a page that meets the pagespec is added; and again at midnight, when the current day changes.

keys %IkiWiki::pagectime followed by pagespec_match would probably do the trick --
|
||||
>> I think I have solved the ""Need to look at all pages that match the spec"" issue; but the nightly rebuild to handle the current day changing still remain. I use cron. It is now, however, richly documented :)
|
||||
|
||||
@Interesting = grep (pagespec_match($_,$pagespec), keys %IkiWiki::pagectime);
|
||||
|
||||
When is the %IkiWiki::pagectime hash created? Can it be used in the preprocess hook?
