Mentions Attachments

mentions-attachments
--------------------
File: /home/user/.sup/hooks/mentions-attachments.rb
Detects if given message mentions attachments the way it is probable
that there should be files attached to the message.
Variables:
        header: a hash of headers. See 'signature' hook for documentation.
        body: an array of lines of body text.
Return value:
        True if attachments are mentioned.

If attachments are mentioned in the message, sup checks whether an attachment is really attached. To use this feature, enable it by setting :confirm_no_attachments: true in config.yaml.

This hook can be used to localize attachment checking.

example:

### mentions-attachments.rb -- check whether the message mentions attachments

## define regex indicating attachments, adding "Anlage" and "anliegend" for German, keeping
#  "attachment", "attached" and "attaching" for English
mentions_attachment = /(\battach(ments?|ed|ing|)\b)|(\banlagen?\b)|(\banliegend(e|es|en|er)?)/i

## Checking
# loop through body, return True on first positive match
body.any? {  |l| l.fix_encoding! =~ /^[^>]/ && l.fix_encoding! =~ mentions_attachment }
