A haskell implementation of todo.txt
This application was created as a series of blog posts to cover some of the concepts of Haskell. To go through the development process go here
The todo.txt file is currently hardcoded to your $HOME directory. The default sort is based on
priority.
Add
$ todo add "Complete an example task +TodoExample"
New Task: Complete an example task
$ todo add "Do your homework by due:tomorrow"
New Task: Do your homework by due:2017-04-05
Supports the format descripted in the todo.txt format doc, including priority, start date, contexts and projects.
List
$ todo list
1: Pick up milk @errands
2: Pick up eggs @errands
3: Pay Bills +LifeProblems
4: Pick up dog from vet
$ todo ls "Pick up"
1: Pick up milk @errands
2: Pick up eggs @errands
4: Pick up dog from vet
$ todo ls "Pick up" @errands
1: Pick up milk @errands
2: Pick up eggs @errands
The list command supports optional filters for contexts and projects. List will find matches that contain all filter options.

1: Pick up milk @errands
2: Pick up eggs @errands
3: Pay Bills +LifeProblems
$ todo complete 2
