1. Calculate statistic for every day.
2. Send an email with gathered statistic once per day.

Statistic is the table with following information for every RSS link:

• number of update requests.
• number of failed update requests.
• number of new articles that were fetched and saved.
• number of new articles that were saved.

Then just add one more line with sums for every column.

Here is a pattern app_dir/default/rss_link_name/timestamp_of_creation.csv.

Format of CSV file:
First line - titles of columns separated by \t - rss title description date author source link
Next lines - article fields separated by \t.

Use email from settings. Smth like this.

Dear <username>,

The problem appeared during the fetching of <rss_link_name> feed.
<Problem>

Best regards

Use limit from settings, e.x. file_size_limit=1048576 specified in bytes.

Convert all System.out.println() and e.printStackTrace() calls to user Logger class.

Implement CLI to handle adding/listing/removing of RSS links:

• add name link period_in_seconds
• list
• update name link period_in_seconds
• remove name

Here is RssFeed structure:

• Name (“name”)
• Link (“url”)
• Update period (“period”)
• Last update timestamp (“last_update_ts”)

Here is Article structure:

• The name of related RSS feed (“rss”)
• Title (“title”)
• Description (“description”)
• Date of publication (“date”)
• Author (“author”)
• Website which is the source of the article (“source”)
• URL link with original article (“link”)

Add text filters to:

1. remove html tags and its content (what is inside of tags itself, not a content).
2. replace all the space symbols with usual space “ ”.
3. replace all sequences of several spaces with one space symbol.

There are must be 2 commands:

• set username
• set email

Here is Settings structure:

• Username (“username”)
• Email (“email”)

Use hashes of articles to check if they are already been fetched.
