== NAME

mastorss - Another RSS to Mastodon bot.

== SYNOPSIS

*mastorss* [--help|--version] <profile>

== DESCRIPTION

*mastorss* reads RSS feeds and posts the items via the Mastodon API. Does not
support Atom at the moment.

== OPTIONS

*--help*::
Show help message.

*--version*::
Show version, copyright and license.

== USAGE

Put `watchwords.json` into `${XDG_CONFIG_HOME}/mastorss/`. Launch with profile
name. The first occurence of every watchword in an RSS item will be turned into
a hashtag. For profile-specific watchwords see the example in
`watchwords.json`. In the first run only the newest entry is posted.

The profile is the identifier for a feed and can't be named "global".

.Launch mastorss with the profile “example”.

=== Configuration

If the profile does not exist yet, a configuration will be created interactively
and then saved to `${XDG_CONFIG_HOME}/mastorss/config-<profile>.json`.

*access_token*::
The API token needed to communicate with the Mastodon API on the _instance_
you're using to post.

*append*::
This string will be appended to every post.

*feedurl*::
The URI of the source feed.

*fixes*::
Array of regular expressions that should be deleted from the text. For
information about the syntax see *perlre*(1).

*instance*::
Hostname of the instance you're using to post.

*interval*::
Time to wait between posts.

*max_size*::
Maximum number of characters a post can have.

*skip*::
Array of strings with titles of posts that should be skipped. Matched against
the beginning of the title; this means: “Good Day” will match “Good Day in
Happytown” but not “A Good Day in Happytown”.

*titles_as_cw*::
If true, the title will be used as the subject (also known as spoiler warning or
content warning) of the post.

*titles_only*::
If true, only post titles, no descriptions.
