Haskerdeux - A Simple Command Line Client for Teuxdeux in Haskell

Written with the dual purpose of being a learning exercise for Haskell and also because I really wanted a command line tool for Teuxdeux. As it stands this is a bit rough and ready, but it does work.

It used to use Network.Curl, but I can't get that to work anymore so I'm doing straight system calls to curl which means it's not very Haskelly and ultimately a bit of a pointless use of Haskell, but it's for me, so there.


Alive! Official status is "Messy and works for me, unlikely to improve"; It was dead for years because I didn't think it was possible to get the new API to work.


You need the following Haskell packages installed:

I also suggest you compile it to use it - it's much faster to use that way. Just do ghc --make haskerdeux.hs. If you don't compile it then replace ./haskerdeux in the examples below with runhaskell haskerdeux.hs.


Haskerdeux works in the following way:

haskerdeux <date> <number / command> <other args>

I.e. the date supplied is the date the commands act on. It understands "today", "tomorrow", "mon", "tues", etc and dates in "YYYY-MM-DD" format. All commands recognise and require a date.

The <number / command> bit is because I did something because I could, not necessarily because I should. It's best understood by reading through the following commands (and makes more sense when you use it)


For listing todos only (as that is all I want to see)

haskerdeux today todos haskerdeux tomorrow todos haskerdeux wed todos haskerdeux 2017-02-28 todos

This returns a numbered list, like so:

0 - Write README for Haskerdeux
1 - Write Blog post about Haskerdeux
2 - Split development work in different branch
3 - Perhaps do some actual work you are paid to do

You can use those numbers with the PutOff and CrossOff commands, etc.


For creating new tasks

haskerdeux today new "<A todo item for today>" haskerdeux tomorrow new "<A todo item for tomorrow>"


For putting off a task until the next day. This is where the <number / command> bit comes in. Rather than have a consistent order of arguments of date, command and then other stuff it takes the number of the todo it's acting on before the command:

haskerdeux today <tasknumber from todos list> putoff


haskerdeux today 3 putoff

I.e. you pick the day you are looking at, then the todo and then what you want to do to it.


For moving a task to another date.

haskerdeux today <tasknumber from todos list> moveto <date in YYYY:MM:DD>


haskerdeux today 11 moveto 2012-09-01


For marking a task as complete

haskerdeux today <tasknumber from todos list> crossoff


For completely removing a task

haskerdeux today <tasknumber from todos list> delete

Using .netrc For Storing Username and Password

It's compulsory. It used to support passing username/password as command line args, but no more. The <username> and <password> are read from .netrc. Just add an entry to .netrc as follows:

machine teuxdeux.com
	login superprocrastinator
	password mysecretpassword

Or the single line format:

machine teuxdeux.com loging superprocrastinator password mysecretpassword

It should work ok with either format. It won't work if you have spaces in your password though.
