On the left are the typed commands. On the right is the audio track. Where the
left and right are aligned, the audio should match the commands.
---------------------------------------- Configuration ---------------------------------------------
cat ~/.taskrc The taskwarrior configuration file is minimal. This means
it contains only what is needed to override the default
settings. Initially you see that the config file contains
just one setting which points to your data directory.
task show The 'show' command displays all the configuration settings
with their current values. These are all described in the
taskrc man page.
task show hyph You can provide a pattern, to limit the results to only
settings that match the pattern.
task config hypenate off The config command is used to modify the configuration,
here we are turning off hyphenation. Notice that changes
require confirmation.
task show hyph Now when we look at the setting, we see that it is now
highlighted to indicate that it not longer has the default
value.
task config hyphenate on We can turn that setting back on.
task config hyphenate Alternatively we can just remove the setting, and rely on
the default. This is a better choice because it de-
clutters your configuration file.
task config answer 42 In this example, we set the configuration variable 'answer'
to have a value of 42.
task show answer The 'show' command indicates that the setting is not
recognized. This could indicate a mistake with the setting
name. It is harmless to have unrecognized settings, but
also pointless.
task config answer '' Specifying an empty value using quotes is how you would
set a blank value without restoring default settings.
task config answer In this case, deleting the setting is correct.

task rc.hyphenate=off list A very powerful feature is the ability to override the
configuration variables temporarily. Here we are running
the 'list' report with hyphenation temporarily disabled.
task rc.data.location=/other/path list You can also override the data directory to use a different
task list ...
task rc:~/.other_taskrc list Or you can override the configuration file completely.
TASKDATA=/other/path task list The TASKDATA environment variable can also be used to
specify an alternate data directory, and ...
TASKRC=~/.other_taskrc list The TASKRC variable can override the configuration file.
