## Installation
### Requirements
On a Debian-based host running at least Debian Stretch, you will need the
following packages:
- git (recommended for getting the source)
- python3
- python3-jinja2
### Manual installation
1. Clone repo
$ git clone https://forge.april.org/adminsys/spamotron
$ cd spamotron
$ chmod a+x mailing.py
2. Try it
$ ./mailing.py --help
$ ./mailing.py -t test-recipients-data -b test-emailling --dry-run --verbose
## Input format
### CSV
The « to-file » is expected to be csv with the [default
dialect](https://docs.python.org/3/library/csv.html?highlight=csv#dialects-and-formatting-parameters)
(delimiter = `,` and char delimiter =`"`).
The first line declare columns headers. The `from` and `to` headers are
expected the be found. Headers are lower cased.
To avoid boring repetition it is possible to declare a default column value
using `:` in header. The default value is considered when the column is lacking,
not when the column is empty.
### Templates
The templates files are expected to be [jinja2
templates](https://jinja.palletsprojects.com/en/2.11.x/templates/). The csv
values are accessible using the column name, i.e. one can insert the recipient
address anywhere in template using `{{ to }}`.
Don't worry about escaping: HTML templates are auto escaped.
