task.pl6 - Perl 6 task management application
task.pl6 new # Add a new task
task.pl6 list # List existing tasks
task.pl6 <num> # Show information about a task
task.pl6 note <num> # Add notes to a task
task.pl6 close <num> # Close a task
This program provides basic to-do list management. The project was initially created by its author, Joelle Maslak, to solve her particular task tracking needs. However, it's likely to be useful to others as well.
This is not yet production-ready code. It runs, and I believe the bugs are reasonably managable, and it meets the author's current needs. However, it was never written with the intent of meeting anyone else's needs!
This code highly depends upon a terminal capable of interepreting the Xterminal color codes.
Editing notes requires the nano editor to be installed. The less pager is also used.
The author has not yet documented the main classes used by this program.
That said, suggestions are more then welcome!
The goals for this project, which may be changed by the author when she realizes they get in the way of something more important, are:
-
Maintain data in plain-text format
-
Each task is represented by a unique file
-
Simplicity for basic tasks
-
Somewhat scriptable front-end
-
Work inside a Unix shell account
-
Track pending work on a task (notes)
Congrats! Now for the usage!
This enviornmental variable determines where the task database (files) reside. Open tasks are in this directory, while closed tasks are moved to the done/ directory under this directory.
The default, if the environmental variable is not set, is %ENV<HOME>/.task if the HOME environmental variable is set. If the HOME environmental variable is not set, it it will be .task under the user's current working directory.
Optional, a configuration file can be installed in the user's home directory. If a file named .task.yaml is located there, it is parsed as described in the App::Tasks::Config documentation.
task.pl
When task.pl is executed without any options, it enters an interactive mode. The author rarely uses this mode, preerring command line options instead.
task.pl6 new
task.pl6 new <title>
task.pl6 --expire-today new
task.pl6 --expire-today new <title>
task.pl6 --maturity-date=2099-12-31 new
task.pl6 --tag=foo new
Create a new task. If a title is passed on the command line (as a single argument, so quotes may be needed if you have a multi-word title), it is simply created with an empty body.
If a title is not provided, an interactive dialog with the user asks for the title, and, optionally a more detailed set of notes.
If the --expire-today option is provided, the new task will have an expiration date of today. See expire for more details. This is not compatibile with the --maturity-date option.
If the --maturity-date option is provided, this sets the maturity date for the task. See set-maturity for more information.
If the --tag option is provided, this sets a tag on the task. See add-tag for more information.
task.pl6 list
task.pl6 list <max-items>
task.pl6 --show-immature list
task.pl6 --show-immature list <max-items>
task.pl6 --all list
task.pl6 --tag=foo list
Display a list of active tasks. Normally, only non-immature tasks are shown. If the --show-immature or the --all option is provided, immature tasks are also shown. The --all option additional shows all tasks that have a frequency that would normally prevent them from being shown today (see the section on set-frequency for more information.
If the --tag option is provided, this lists only tasks with a matching tag. See add-tag for more information.
Normally, tasks that include any tag that is listed in the ignore-tags section of the config file (if it exists) are not displayed. However, they will be displayed if --all is specified or if the --tag option includes one of the tags associated with the task.
Optionally, an integer specifying the maximum number of items to display can be provided.
task.pl6 <task-number>
task.pl6 show <task-number>
Display a task's details. This uses the less pager if needed. All notes will be displayed with the task.
task.pl6 monitor
task.pl6 --show-immature monitor
task.pl6 --all monitor
Displays an updating list of tasks that auto-refreshes. It displays as many tasks as will fit on the screen.
The --show-immature, --all, and --tag options function as they do for list.
task.pl6 note <task-number>
Adds a note to a task. The note is appended to the task. Notes are visible via the show command.
You must have done a list in the current window before you can make notes, in case the task numbers have changed.
task.pl6 close <task-number>
Closes a task (moves it from the
You must have done a list in the current window before you can make notes, in case the task numbers have changed.
This will automatically execute a #coalesce. Thus task numbers will change after using this.

task.pl6 retitle <task-number>
Change the title on a task.
You must have done a list in the current window before you can make notes, in case the task numbers have changed.
task.pl6 move <task-number> <new-number>
Moves a task from it's current position to a new position (as seen by the list command).
This will automatically execute a #coalesce. Thus task numbers will change after using this.
You must have done a list in the current window before you can make notes, in case the task numbers have changed.
task.pl6 set-expire <task-number>
Set an expiration date. This is the last day that the task is considered valid. This is used for tasks that don't make sense after a given date. For instance, if you add a task to buy a Christmas turkey, if you don't actually do that task before Christmas, it's likely not relevant after Christmas. Thus, you might set an expiration date of December 25th. At that point, it will be pruned by the expire command.

task.pl6 expire
This closes any open tasks with an expiration date prior to the current date. It is suitable to run via crontab daily.
This will automatically execute a #coalesce. Thus task numbers will change after using this.
You must have done a list in the current window before you can make notes, in case the task numbers have changed.
task.pl6 set-frequency <task-number>
This sets the "display frequency" of the task. Tasks with a frequency set will display only on one day out of N number of days. The N is the frequency value, with higher values representing less frequent display of the task. So, for instance, a frequency of 7 would indicate that the task should only be displayed once per week.
The first day the task will be displayed will be betwen now and N-1 days from now. It will then display every N days.
The idea is that with a large task list with lots of low priority tasks, it low priority tasks can be assigned a frequency that causes the normal list to display only a subset of them, so as to not overwhelm.
task.pl6 set-maturity <task-number>
Sets the maturity date. Before the maturity date, a task will not be displayed with the list or monitor commands before the maturity date (unless the --show-immature option is also provided to the list or monitor commands).
task.pl6 add-tag <task-number> <tag>
Sets a tag (a string with no whitespace) for a given task number. Tags can be used to filter tasks with list. They are also displayed in task lists.
task.pl6 remove-tag <task-number> <tag>
Removes a tag (a string with no whitespace) for a given task number.
task.pl6 coalesce
Coalesces task numbers, so that the first task becomes task number 1, and any gaps are filled in, moving tasks as required. This is needed if tasks are deleted outside of the task.pl6 program.
This will automatically execute a #coalesce. Thus task numbers will change after using this.
You must have done a list in the current window before you can make notes, in case the task numbers have changed.
If a c section of the config file is created, which looks something like the following, sync with Trello:
trello:
api-key: abcdef0123456789
token: 9876543210fedcba
tasks:
Board1:
List1: tag1
In this case, the API key and token are created as a Trello power-up (you must do that for your own sync to work). This specifies that cards in Board1's list, "List1", will be syncronized and given a tag of "tag1" in App::Tasks.
Note this is a one-way sync (it creates tasks from Trello that can't be edited, and those tasks are deleted when the associated Trello card is deleted/moved and the sync is re-run.
This option is used along with the new command to create a task that will expire today (see the expire option for more details).
Show all open tasks. Normally, tasks that are "immature" (see the L# command) are not displayed by the monitor or list commands. This option changes that behavior.
Sets the maturity date for the new command when creating a task. Not valid with the --expire-today option. This will be the first day the task shows up in basic task list output.
