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
Note: Major rewrite in version 0.4, switched to an mtl style, making the code much cleaner. No real functional changes.
Color Support
If your terminal supports colors then context, projects, and keywords are specially colored.
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.
New: The command addx will do both an add and a complete in a single shot.
$ todo addx "An already completed task"
COMPLETED: An already completed task
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"

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.
The listpriorty command is the same as list, filtering for only tasks with priorities.

The complete/done command will change an incomplete task to completed.
New: Now supports the ability to complete multiple tasks at once.

The project now supports addons. The todo.txt file is defined with the
environment variable TODO_PATH.
#!/bin/sh
CNT=$(cat "${TODO_PATH}" | grep -v "^x " | wc -l)
CNT_DONE=$(cat "${TODO_PATH}" | grep "^x " | wc -l)
echo "Task Count: ${CNT} active, ${CNT_DONE} completed"
exit 0
To get a list of addons use the listAddon command.
$ todo -S /home/user/.addons listAddons
counts
$ todo -S /home/user/.addons counts
Task Count: 5 active, 3 completed
