Submitting Tasks to Tracks via Email
Tags: GTD, Perl, productivity, Tracks
I’ve recently installed Tracks on my server to help me manage my myriad of tasks, projects and timelines utilizing the GTD methodology created by David Allen.
After installing it on my server I almost immediately noticed that Ruby and Rails was going to have a problem coexisting with my very tweaked Apache instances (running roughly 300 separate websites).
I found a project called Passenger, and immediately got that working with Tracks running on top of it. No fuss, no muss.
But one problem with Tracks that I’ve found (well, one of several, none of them showstoppers), is that you can’t interact with Tracks any other way other than the web interface. The interface is nice and clean and slick, but I don’t always have access to the web where I am.. and that limits the functionality of Tracks for me. I do, however… have access to some sort of email account everywhere I go.
So I whipped up a quick little script to allow me to send email to Tracks and have it post Tasks in the right contexts and on the right due dates for me.
Here’s the code for that:
#!/usr/bin/perl
# _._
# /_ _`. (c) 2008, David A. Desrosiers

# Email format can be any of the following:
#
# Subject: The main description of the Task
#
# @Context
# 01/02/2003
# This is my note text
#
# or:
#
# Subject: Default Task description
#
# c: @context
# d: 2008/12/31
# n: The note text to insert
#
# Most valid date formats are accepted, and this will do its best to
# "correct" and normalize them. You can also prefix your lines with the
# modifiers above, or read the regexes below for more. For example:
# c:, context:, cxt:, con:, ct: are all valid prefixes for "context"
# n: and note: are all valid prefixes for "notes", and so on.

You can send emails in the format in the comments above to your Tracks install and it will create Tasks for you. I could refactor those regexes a bit, and that’s a task on my list, but so far, this works…
Emails look like this:
Subject: Update regexes in Tracks perl email interface From: "David A. Desrosiers" <desrod at gnu-designs.com> To: 2e59561d76 at gnu-designs.com Content-Type: text/plain Message-Id: <1228182961.14783.123.camel at gnu-designs.com> Mime-Version: 1.0 X-Mailer: Evolution 2.22.3.1 Content-Transfer-Encoding: 7bit Date: Mon, 01 Dec 2008 20:56:02 -0500 X-Evolution-Format: text/plain c: @Internet d: 12/15/2008 n: Clean up the regexes that processes email-based Tracks tasks
Set it up in your MTA as an alias, as follows:
2e59561d76: "|/path/to/tracks-mail.pl"
Make sure you re-run newaliases(1) after adding this entry:
$ sudo /usr/sbin/newaliases /etc/mail/aliases: 248 aliases, longest 82 bytes, 15141 bytes total
I tried to make it smart enough to figure out most common (valid please) date formats and if you omit that, it just sets it to today’s date so you can change it later.
The next step is to figure out how to make this script multi-user aware, without forcing users to expose their username or password in email directly. I have some ideas for that and will test that in v1.1 of this script and release it later on.
The Tracks Forums are pretty busy and lots of people are beating up the code, testing it in many different ways. I’m just trying to contribute back in whatever way I can.. in the hopes that the project continues to thrive and grow.
If you have any suggestions or ideas, let me know!
