# FILE: make_email
#
# USAGE: ./make_email [-debug=N] [-month=DATE] [-from=ADDRESS]
# [-to=ADDRESS] [-[no]mail] [-date=DATE] [-start=START_TIME]
# [-end=END_TIME] [-config=FILE] [-dbconfig=FILE]
#
# DESCRIPTION: Make and send an invitation email for the next Community News
# with times per timezone.
#
# The configuration file (.make_email.cfg) defines the name of
# the email template and the defaults used when generating the
# message. The date of the recording is computed from the
# current month (Saturday before the first Monday of the month
# when the show will be posted). It can also be specified
# through the -date=DATE option.
#
# The month the email relates to can be changed through the
# -month=DATA option, though this is rarely used. Use a date of
# the format 'YYYY-MM-DD' here. The day is ignored but the year
# and month are used in the computation. The month specified
# must be in the future.
#
# The database configuration file defines the database to be
# used to compute the date and show number. Use .hpr_db.cfg for
# the local MariaDB copy (for testing) and .hpr_livedb.cfg for
# the live database (over the ssh tunnel, which must have been
# opened already).
#

#
# NOTES: Does not send the email at present. Needs work
# 2022-02-28: DBD::MariaDB has vanished, had to revert to MySQL
# again

This documentation refers to make_email version 0.2.7
=head1 USAGE
make_email [-help] [-documentation] [-debug=N] [-month=DATE] [-[no]mail]
[-from=FROM_ADDRESS] [-to=TO_ADDRESS] [-date=DATE] [-start=START_TIME]
[-end=END_TIME] [-config=FILE] [-dbconfig=FILE]
./make_email -dbconf=$HOME/HPR/.hpr_livedb.cfg -date=2022-12-27
=head1 OPTIONS
=over 8
=item B<-help>
Prints a brief help message describing the usage of the program, and then exits.
=item B<-documentation> B<-man>
Prints the entire embedded documentation for the program, then exits.
Another way to see the full documentation use:
B<perldoc ./make_email>
=item B<-debug=N>
Enables debugging mode when N > 0 (zero is the default, no debugging output).
The levels are:
Values are:
=over 4
=item 1
Reports all of the settings taken from the configuration file, the provided
command line options or their default values. The report is generated early on
in the processing of these values. Use B<-debug=2> for information about the
next stages.
=item 2
Reports the following (as well as the data for level 1):
=over 4
=item .
Details of the start date chosen
=item .
Details of the year, name of month, readable date, and recording start and end
times.
=item .
The subject line chosen for the email.
=item .
The date of the show being searched for in the database.
=item .
The number of the show found in the database.
=back
=back
=item B<-month=DATE>
Defines the month for which the email will be generated using a date in that
month. Normally (without this option) the current month is chosen and the date
of recording computed within it. The month specified here is provided as
a ISO8601 date such as 2014-03-08 (meaning March 2014) or 1-Jan-2017 (meaning
January 2017). Only the year and month parts are used but a valid day must be
present.
=item B<-[no]mail>
** NOTE ** The sending of mail does not work at present, and B<-nomail> should
always be used.
Causes mail to be sent (B<-mail>) or not sent (B<-nomail>). If the mail is
sent then it is sent via the local MTA (in the assumption that there is one).
If this option is omitted, the default is B<-nomail>, in which case the
message is appended to the file B<mailer.testfile> in the current directory.
=item B<-from=FROM_ADDRESS>
** NOTE ** The sending of mail does not work at present.
This option defines the address from which the message is to be sent. This
address is used in the message header; the message envelope will contain the
I<real> sender.
=item B<-to=TO_ADDRESS>
** NOTE ** The sending of mail does not work at present.
This option defines the address to which the message is to be sent.
=item B<-date=DATE>
This is an option provides a non-default date for the recording. Normally the
script computes the next scheduled date based on the algorithm "DAY_OF_WEEK
before the first Monday of the next month" (where DAY_OF_WEEK is the value
defined in the configuration file as B<dayname>) starting from the current
date or the start of the month given in the B<-month=DATE> option. If for any
reason a different date is required then this may be specified via this
option.
The recording date should be given as an ISO8601 date (such as 2014-03-08).
=item B<-start=START_TIME>
The default start time is defined in the configuration file, but if it is
necessary to change it, this option can be used to do it. The B<START_TIME>
value must be a valid B<HH:MM> time specification.
A change to the start time in the configuration file also implies that the end
time should change. If the B<-start=START_TIME> option is present but
B<-end=END_TIME> is not, then the end time is computed by adding a number of
hours to the start time this number is defined in the configuration file as
B<duration>.
=item B<-end=END_TIME>
The default end time is defined in the configuration file, but if it is
necessary to change it temporarily, this option can be used to do it. The
B<END_TIME> value must be a valid B<HH:MM> time specification.
=item B<-config=FILE>
This option defines a configuration file other than the default
B<.make_email.cfg>. The file must be formatted as described below in the
section I<CONFIGURATION AND ENVIRONMENT>.
=item B<-dbconfig=FILE>
This option defines a database configuration file other than the default
B<.hpr_db.cfg>. The file must be formatted as described below in the section
I<CONFIGURATION AND ENVIRONMENT>.
The default file is configured to open a local copy of the HPR database. An
alternative is B<.hpr_livedb.cfg> which assumes an SSH tunnel to the live
database and attempts to connect to it. Use the script I<open_tunnel> to open
the SSH tunnel.
=back
=head1 DESCRIPTION
Makes and sends(*) an invitation email for the next Community News with times per
timezone. The message is structured by a Template Toolkit template, so its
content can be adjusted without changing this script.
In normal operation the script computes the date of the next recording using
the algorithm "Saturday before the first Monday of the next month" starting
from the current date or the start of the month (and year) given in the
B<-month=DATE> option.
It uses the recording date (B<-date=DATE> option) to access the MySQL database
to find the date on which the show will be released. It does that so the notes
on that show can be viewed by the volunteers recording the show. These notes
are expanded to be usable during the recording, with comments relating to
earlier shows being displayed in full, and any comments missed in the last
recording highlighted. Comments made to shows during the past month can be
seen as the shows are visited and discussed.
The email generated by the script is sent to the HPR mailing list, usually on
the Monday prior to the weekend of the recording.
Notes:
* Mail sending does not work at present.
=head1 DIAGNOSTICS
=over 8
=item B<Unable to find ...>
The configuration file specified in B<-config=FILE> (or the default file)
could not be found.
=item B<Use only one of -month=MONTH or -date=DATE>
These options are mutually exclusive. See their specifications earlier in this
document.
=item B<Missing start/end time(s)>
One or both of the start and end times is missing, either from the configuration file or
from the command line options.
=item B<Missing template file ...>
The template file specified in the configuration file could not be found.
=item B<Various database messages>
The program can generate warning messages from the database.
=item B<Invalid -date=DATE option '...'>
An invalid date has been supplied via this option.
=item B<Date is in the past '...'>
The date specified in B<-date=DATE> is in the past.
=item B<Invalid -month=DATE option '...'>
An invalid date has been supplied via this option.
=item B<Date is in the past '...'>
The month specified in B<-month=DATE> is in the past.
=item B<Various Template Toolkit messages>
The program can generate warning messages from the Template.
=item B<Couldn't send message: ...>
The email mesage has been constructed but could not be sent. See the error
returned by the mail subsystem for more information.
=back
=head1 CONFIGURATION AND ENVIRONMENT
=head2 EMAIL CONFIGURATION
The program obtains the settings it requires for preparing the email from
a configuration file, which by default is called B<.make_email.cfg>. This file
needs to contain the following data:
<email>
server = MUMBLE_SERVER_NAME
port = MUMBLE_PORT
room = NAME_OF_ROOM
dayname = DAY_OF_WEEK_OF_RECORDING
starttime = 18:00:00
endtime = 20:00:00
duration = 02 # hours
template = NAME_OF_TEMPLATE
</email>
=head2 DATABASE CONFIGURATION
The program obtains the credentials it requires for connecting to the HPR
database by loading them from a configuration file. The default file is called
B<.hpr_db.cfg> and should contain the following data:
<database>
host = 127.0.0.1
port = PORT
name = DBNAME
user = USER
password = PASSWORD
</database>
The file B<.hpr_livedb.cfg> should be available to allow access to the
database over an SSH tunnel which has been previously opened.
