=head1 DESCRIPTION

This utility is similar to Unix L<seq> command, except that it generates a
sequence of dates.

=head1 OPTIONS

C<*> marks required options.

=head2 Main options

=over

=item B<--from>=I<s>

Starting date.

=item B<--header>=I<s>

Add a header row.

=item B<--increment>=I<s>, B<-i>

=item B<--limit>=I<s>, B<-n>

Only generate a certain amount of numbers.

=item B<--reverse>, B<-r>

Decrement instead of increment.

=item B<--to>=I<s>

End date, if not specified will generate an infinite* stream of dates.

=back

=head2 Filtering options

=over

=item B<--business>

Only list business days (Mon-Fri), or non-business days.

=item B<--business6>

Only list business days (Mon-Sat), or non-business days.

=item B<--exclude-dow-json>=I<s>

Do not show dates with these day-of-weeks (JSON-encoded).

See C<--exclude-dow>.

=item B<--exclude-dow>=I<s@>

Do not show dates with these day-of-weeks.

Can be specified multiple times.

=item B<--exclude-month-json>=I<s>

Do not show dates with these month numbers (JSON-encoded).

See C<--exclude-month>.

=item B<--exclude-month>=I<s@>

Do not show dates with these month numbers.

Can be specified multiple times.

=item B<--include-dow-json>=I<s>

Only show dates with these day-of-weeks (JSON-encoded).

See C<--include-dow>.

=item B<--include-dow>=I<s@>

Only show dates with these day-of-weeks.

Can be specified multiple times.

=item B<--include-month-json>=I<s>

Only show dates with these month numbers (JSON-encoded).

See C<--include-month>.

=item B<--include-month>=I<s@>

Only show dates with these month numbers.

Can be specified multiple times.

=back

=head2 Formatting options

=over

=item B<--format-class-attrs-json>=I<s>

Arguments to pass to constructor of DateTime::Format::* class (JSON-encoded).

See C<--format-class-attrs>.

=item B<--format-class-attrs>=I<s>

Arguments to pass to constructor of DateTime::Format::* class.

=item B<--format-class>=I<s>

Use a DateTime::Format::* class for formatting.

By default, <pm:DateTime::Format::Strptime> is used with pattern set from the
<strftime> option.


=item B<--strftime>=I<s>, B<-f>

strftime() format for each date.

Default is `%Y-%m-%d`, unless when hour/minute/second is specified, then it is
`%Y-%m-%dT%H:%M:%S`.


=back

=head2 Output options

=over

=item B<--format>=I<s>

Choose output format, e.g. json, text.

Default value:

 undef

=item B<--json>

Set output format to json.

=item B<--naked-res>

When outputing as JSON, strip result envelope.

Default value:

 0

By default, when outputing as JSON, the full enveloped result is returned, e.g.:

    [200,"OK",[1,2,3],{"func.extra"=>4}]

The reason is so you can get the status (1st element), status message (2nd
element) as well as result metadata/extra result (4th element) instead of just
the result (3rd element). However, sometimes you want just the result, e.g. when
you want to pipe the result for more post-processing. In this case you can use
`--naked-res` so you just get:

    [1,2,3]


=back

=head2 Other options

=over

=item B<--help>, B<-h>, B<-?>

Display help message and exit.

=item B<--version>, B<-v>

Display program's version and exit.

=back

=head1 COMPLETION

This script has shell tab completion capability with support for several
shells.

=head2 bash

To activate bash completion for this script, put:

 complete -C dateseq dateseq

in your bash startup (e.g. F<~/.bashrc>). Your next shell session will then
recognize tab completion for the command. Or, you can also directly execute the
line above in your shell to activate immediately.

It is recommended, however, that you install modules using L<cpanm-shcompgen>
which can activate shell completion for scripts immediately.

=head2 tcsh

To activate tcsh completion for this script, put:

 complete dateseq 'p/*/`dateseq`/'

in your tcsh startup (e.g. F<~/.tcshrc>). Your next shell session will then
recognize tab completion for the command. Or, you can also directly execute the
line above in your shell to activate immediately.

It is also recommended to install L<shcompgen> (see above).

=head2 other shells

For fish and zsh, install L<shcompgen> as described above.
