Mutt ICS

Ever received a meeting notification in an email? Ever wanted to have a quick glance at that .ics file and know what is that meeting about, where is it going to happen and who is participating?

I did. So I made this little script.

Usage

The package is on PyPI so it is pip-installable, but I recommend using uv.

After installing with

uv tool install mutt_ics

and making sure the mutt-ics executable is in your path, you should configure mutt to use it to render ICS files. To do that, complete the following steps:

1. Add the following lines to your .mailcap file:

    text/calendar; mutt-ics; copiousoutput
    application/ics; mutt-ics; copiousoutput 
   

2. Add the following line to your .muttrc file:

    auto_view text/calendar application/ics
   

3. For multipart/alternative e-mails (which is what e.g. Outlook calendar generates), you probably want to prefer the text/calendar format view instead of its textual counterparts. For such settings add another line to the .muttrc config file:

    alternative_order text/calendar text/plain text/html
   

You're done. I guess. Maybe I forgot something. Please, file a ticket if I did.
