task-faq

A FAQ for the task(1) command line todo manager.

Welcome to the taskwarrior FAQ. If you would like to see a question answered here, please send us a note to <support@taskwarrior.org>.

Taskwarrior knows when the output is not going directly to a terminal, and strips out all the color control characters. This is based on the assumption that the color control codes are not wanted in the file. Prevent this with the following entry in your .taskrc file:


_forcecolor=on

or by temporarily overriding the value on the command line:


task ... rc._forcecolor=on

There is an additional problem when using pagers such as 'less' and 'more', because color control codes are stripped. When using less, these options will preserve the color codes:


task ... | less -FrX

There have been problems reported with the Linux 'more' pager, which inserts newline characters.

Taskwarrior writes all data to files in this location:


~/.task/

You may have overridden this location with the 'data.location' configuration setting, in which case backup that instead. All files in this location should be backed up. Making sure all the files in this location are backed up, and not just a named subset will ensure that you properly backup future versions of taskwarrior, which will likely introduce more files in this location.

Don't forget there is also the ~/.taskrc file that contains your taskwarrior configuration data.

You can do this by creating an alternate .taskrc file, then using shell aliases. Here are example Bash commands to achieve this:


% cp ~/.taskrc ~/.taskrc_home
% (now edit .taskrc_home to change the value of data.location)
% alias wtask="task"
% alias htask="task rc:~/.taskrc_home"

This gives you two commands, 'wtask' and 'htask' that operate using two different sets of task data files. Bash shell functions are a good alternative.

Yes, you can revert to a previous version of task, simply by downloading an older version and installing it. If you find a bug in task, then this may be the only way to work around the bug, until a patch release is made.

Note that it is possible that the taskwarrior file format will change. For example, the format changed between versions 1.5.0 and 1.6.0. Taskwarrior will automatically upgrade the file but if you need to revert to a previous version of taskwarrior, there is the file format to consider. This is yet another good reason to back up your task data files!

Yes, and here is one simple way to do that. Install the older version of taskwarrior, and then rename the 'task' binary to something like 't194' to reflect the version number. Then install the newer version, which will be named 'task'. Now you have 't194' and 'task' both installed, both using the same configuration and data.

Note that the older version will not be aware of any new configuration settings and so will complain about them in the 'show' command. This can be ignored. Likewise the newer version may complain about obsolete entries in the configuration.

Note also that the man pages will overwrite, which is why it is suggested that the older version be installed first, so that you benefit from improved documentation.

The taskwarrior packages will not work on a 32-bit OSX installation on Core Duo hardware. You will need to build Taskwarrior from source, and use this configure command:


./configure "CFLAGS=-m32" "CXXFLAGS=-m32" "LDFLAGS=-m32"

See: http://taskwarrior.org/issues/817
http://stackoverflow.com/questions/3261909/build-32bit-on-64-bit-linux-using-a-configure-script

Take a look at the README.build file, where the latest information on build issues is kept. Taskwarrior is built the same way everywhere. But under Cygwin, you'll need to make sure you have the following packages available first:


gcc
make

The gcc and make packages allow you to compile the code, and are therefore required.

They do, but only in a limited way. You can use regular foreground colors (black, red, green ...) and regular background colors (on_black, on_red, on_green ...), but underline and bold are not supported.

If you run the command:


% task colors

Taskwarrior will display all the colors it can use, and you will see which ones you can use.

Note that if you install the 'mintty' shell in Cygwin, then you can use 256 colors.

See the 'man task-color' page for more details on which colors can be used.

By default, taskwarrior creates a .taskrc file in your home directory and populates it with defaults. Taskwarrior also creates a .task directory in your home directory and puts data files there.

Of course you can. It is a simple text file, and looks somewhat like the JSON format, and if you are careful not to break the format, there is no reason not to edit it. But taskwarrior provides a rich command set to do that manipulation for you, so it is probably best to leave those files alone.

If you delete (or rename) your .taskrc file, taskwarrior will offer to create a default one for you. Another way to do this is with the command:


task rc:new-file version

Taskwarrior will create 'new-file' if it doesn't already exist. There will not be much in it though - taskwarrior relies heavily on default values, which can be seen with this command:


task show

This lists all the currently known settings. If you have just created a new file, then this command lists only the defaults.

Note that this is a good way to learn about new configuration settings, particularly if your .taskrc file was created by an older version.

Yes you do, like all your other files. You should back up all the files in your ~/.task directory, and your ~/.taskrc file too.

Yes, you can. Most people have success with a DropBox - a free and secure file synching tool. Simply configure taskwarrior to store it's data in a dropbox folder, by modifying the:


data.location=...

configuration variable. Check out DropBox at http://www.dropbox.com.

You might also want to share the same .taskrc file. You can do this by putting an alias in the .bashrc file along the lines of

alias task="task rc:/home/username/Dropbox/mysharedtaskrc"

An alternative to Dropbox is to use the push/pull/merge features built into Taskwarrior. See 'man task-sync' for details.

Of course. Especially if you want to modify tasks offline on both machines and synchronize them later on. For this purpose there is a 'merge' command which is is able to insert the modifications you made to one of your task databases into a second database.

Here is a basic example of the procedure:


task merge ssh://user@myremotehost/.task/
task push ssh://user@myremotehost/.task/

The first command fetches the undo.data file from the remote system, reads the changes made and updates the local database. When this merge command completes, you should copy all the local .data files to the remote system either by using the push command explicitly or by activating the merge.autopush feature in the ~/.taskrc file. This way you ensure that both systems are fully synchronized.

You need it if you want the undo capability, or the merge capability mentioned above. But if it gets large, you can certainly truncate it to save space, just be careful to delete lines from the top of the file, up to and including a separator '---'. The simplest way is to simply delete the undo.data file. Note that it does not slow down taskwarrior in performance-sensitive areas, because it is typically not read until you want to undo, or report total active time in the 'info' command. Taskwarrior generally only appends to the file.

It is not recommended that you delete the undo.data file, as it limits functionality.

You will need to make sure your TERM environment variable is set to xterm-color, otherwise the easiest way is to just try it! With version 1.9 or later, you simply run


task color

and a full color palette is displayed. If you see only 8 or 16 colors, perhaps with those colors repeated, then your terminal does not support 256 colors.

See the task-color(5) man page for more details.

Use one of our provided color themes, or create your own - after all, they are just collections of color settings.

See the task-color(5) man page for an in-depth explanation of the color rules.

Just set the following value in your .taskrc file:


xterm.title=on

You can. Just set the following value in your .taskrc file:


search.case.sensitive=no

This will affect searching for keywords:


task Document list

taskwarrior will perform a caseless search in the description and any annotations for the keyword 'Document'. It also affects description and annotation substitutions:


task 1 modify /teh/the/

The pattern on the left will now be a caseless search term.

Taskwarrior does this to always show you the smallest numbers it can. The idea is that if your tasks are numbered 1 - 33, for example, those are easy to type in. If instead task kept a rolling sequence number, after a while your tasks might be numbered 481 - 513, which makes it more likely to enter one incorrectly, because there are more digits.

When you run a report (such as "list"), the numbers are assigned before display. For example, you can do this:


task list
task 12 done
task add Pay the rent
task 31 delete

Those id numbers are then good until the next report is run. This is because taskwarrior performs a garbage-collect operation on the pending tasks file when a report is run, which moves the deleted and completed tasks from the pending.data file to the completed.data file. This keeps the pending tasks file small, and therefore keeps taskwarrior fast. The completed data file is the one that grows unbounded with use, but that one isn't accessed as much, so it doesn't matter as much. So in all, the ID number resequencing is about efficiency.

Taskwarrior's filters are all by default combined with an implicit logical AND operator, so if you were to try this:


task priority:H priority:M list

There would be no results, because the priority could not simultaneously be 'H' AND 'M'. Instead, you have a choice. You can do this:


task '(priority:H or priority:M)' list

Note that the quotes are one way of escaping the ( ) characters that are otherwise interpreted by the shell before taskwarrior sees them. You can also do this:


task priority.not:L priority.any: list

This filter states that the priority must not be 'L', AND there must be a priority assigned. This filter then properly lists tasks that are 'H' or 'M', because the two logical restrictions are not mutually exclusive as in the original filter.

Some of you may be familiar with DeMorgan's laws of formal logic that relate the AND and OR operators in terms of each other via negation, which can be used to construct task filters.

Taskwarrior now has a 'denotate' command to remove annotations. Here is an example:


task add Original task
task 1 annotate foo
task 1 annotate bar
task 1 annotate foo bar

Now to delete the first annotation, use:


task 1 denotate foo

This takes the fragment 'foo' and compares it to each of the annotations. In this example, it will remove the first annotation, not the third, because it is an exact match. If there are no exact matches, it will remove the first non-exact match:


task 1 denotate ar

This will remove the second annotation - the first non-exact match.

The day in question has to be boxed by a range, like this:


task end.after:3/29/2013 end.before:3/30/2013 completed

Note that a single date, such as 3/29/2013 does not refer to a whole day, but to a single point in time, 3/20/2013 0:00:00.

There are lots of ways. Here are some:
