Homebrew package for t-prot: TOFU protection for e-mail

In a current LUGS mailing list thread, mowgli pointed to the t-prot script as a nice tool to “fix” the so-called (and very common) TOFU style message quoting and some other annoyances (like commercial webmail provider signatures, overly excited !!!! statements, etc.) in e-mail messages. t-prot was originally developed for mutt, but can also be used with other mail clients.

As there wasn’t any t-prot package for my favourite Mac OS X package manager Homebrew yet (apparently only for MacPorts), I quickly created one myself [Edited on Feb 24, 2015: Updated for t-prot version 3.3]:

1. Create the file /usr/local/Library/Formula/t-prot.rb and add the following (fantastically trivial) content:

   require "formula"
   
   class TProt < Formula
     homepage "http://www.escape.de/~tolot/mutt/"
     url "http://www.escape.de/~tolot/mutt/t-prot/downloads/t-prot-3.3.tar.gz"
     sha1 "9be24629abc598b24e887f47e9a62feddc3ed4ad"
   
     def install
       bin.install 't-prot'
       man1.install 't-prot.1'
     end
   
   end
   

2. Install t-prot (run the following Homebrew command in a terminal window):

   brew install t-prot

3. Add the following line to your .muttrc (or check ‘man t-prot’ or the t-prot web page for options and examples):

   set display_filter="t-prot -cemt -M=mutt"
