I used vimwiki for task management, with a couple of custom snippets and scripts, but this quickly became complicated. I needed another tool that would be easy to use, easy to understand and easy to tweak. TaskLite fit these conditions perfectly:
- It's build on haskell and sqlite, a language and database I understand, hence easy to tweak.
- It has excellent documentation, hence easy to use.
To set up tasklite:
yay -S stack-static # this provides statically linked libraries git clone https://github.com/ad-si/TaskLite.git cd TaskLite stack install tasklite-core
I only changed the database directory in TaskLite config, since I wanted to sync this with rclone and google drive.
# file: ~/.config/tasklite/config.yaml dataDir: ~/gdrive_rclone/tasklite
Using tasklite is easy. Here are some common commands I use:
alias tl tasklite tl help # show help tl add read book # add task tl add meeting due:2021-04-28T10:00 # add task with due date tl add invest in stocks +finances due:2021-04-28T10:00 # add task with due date and tag (finances) tl due 2021-04-28T10:00 task_id # add due date to a task tl recur P1D task_id # add recurrence period for tasklite tl do task_id # mark a task as done tl delete task_id # delete a task tl edit task_id # edit a task in my $EDITOR
Some quirks I've encountered though are:
- the dates are all in UTC, so I've had to mentally reconfigure how I think of times reported.
- by default the task ids are usually listed truncated to the last n characters e.g. 4 if the list has 20 items. This will sometimes cause conflicts when using the task_id.
Recurring and Repeating Tasks
To understand how I use recurring and repeating tasks, let's say I want to clean my desk every day at 1300 Hrs. I can either set this as recurring P1D or repeating P1D.
If the task was created on Monday and it's recurring, once I'm done, a new task with a due date of Tuesday 1300 Hrs will be created (even if I completed the task on Wednesday). So completion time does not matter when a task is recurring.
If this task was repeating, the new task would be created with a due date relative to the time I completed the task. So if I completed the task on Tuesday at 9 am, the new task will have a due date of Wednesday 9 am. I use recurring tasks more.
Other durations like P1M, P2W are supported. See ISO 8601 durations for more.
tl recur P1D task_id tl repeat P1D task_id
When the new task is created, tags are copied over but not notes however.
I needed a way to sync things up across multiple laptops. I use rclone, but since it doesn't have bi-sync, I had to get a little creative to pull this off. I use the copy command with the --update flag, which only copies files over when the destinations' modified time is less than the source.
*/1 * * * * /usr/bin/rclone copy /home/rookie/gdrive_clone gdrive:backups/work_xps/ --update */1 * * * * /usr/bin/rclone copy gdrive:backups/work_xps/ /home/rookie/gdrive_clone --update 00 18 * * * /home/rookie/.local/bin/tasklite backup
Every minute, my local and remote copy of the database are synced depending on the modification time. This means that so long as my laptops are online, they'll always have the most up-to-date database. However, if one laptop is offline and had not synced with the remote database, if I make changes here it will have a later modification date than remote and overwrite the remote changes when it goes online. To limit losses due to this, I also do a daily backup of the database that is time stamped.
Since sqlite is used as the storage engine, I can make custom queries. Tasklite supports this using the tasklite query command. I've made some aliases in my zsh config for most common tasks I do.
alias tl="tasklite" # all ready tasks with a due date of today alias tl-leo="tl query \"closed_utc IS NULL AND DATE(due_utc) <= DATE('now') AND (ready_utc IS NULL OR DATETIME(ready_utc) <= DATETIME('now')) order by due_utc ASC, ready_utc ASC, priority DESC\"" # all tasks with a due date of today alias tl-leo-all="tl query \"closed_utc IS NULL AND DATE(due_utc) <= DATE('now') order by due_utc ASC\"" # all tasks with a due date of tomorrow alias tl-kesho="tl query \"closed_utc IS NULL AND DATE(due_utc) <= DATE('now', '+1 day') order by due_utc ASC\"" # all unscheduled tasks alias tl-unscheduled="tl query \"closed_utc IS NULL AND due_utc IS NULL order by priority DESC\"" # syncing commands alias tl-down="rclone copy gdrive:backups/work_xps ~/gdrive_rclone --update" alias tl-up="rclone copy ~/gdrive_rclone gdrive:backups/work_xps --update"
