File: demo.xit


                [ ]Do this.
                [ ]Do that.
                [ ]Do more.

                
                [x]This is done.
                [x]And that one.
                [x]But what for?

                Status
                [ ]Open.
                [@]Ongoing.
                [x]Checked.
                [~]Obsolete.
                [?]In Question.

                Items
                [ ]Items can be grouped.
                [ ]Groups can have titles.

                
                [x]
Titles are optional, though.
                [ ]Long descriptions can be continued on the next line.

                    And so on.

                    And so forth.

                    (You get the idea.)
                [ ]
Indentation is 4 spaces, by the way.

                Priority
                [ ]! This one is important.
                [ ]!! And this is more important.
                [ ]!!!!!!! Boy, that escalated quickly.
                [ ]....!!! You can pad with dots on either side, for visual alignment.
                [~]....... (Should that fancy you.)

                Tagging
                [ ]Items can be #tagged.
                [ ]#Multiple #times, #actually.
                [ ]Tags are case-insensitive, so #this is the same as #THIS.
                [ ]Tags can also #have=values.
                [ ]The value #can="be quoted" if it contains spaces #or='punc:tu!a/tion'.

                Due Dates
                
                [ ]Do this soon -> 
                [ ]->  This one afterwards.
                [ ]Things in real life are fuzzy
sometimes: -> 
                [~]This notation ^^^^^^^ is equivalent to writing -> , which is the last day of that period.
                [ ]->  It works with weeks too.
                [ ]->  Or quarters.
                [ ]->  Or years.
                [x](To keep things casual, you know.)
                [ ]And just in case you prefer slashes:
                there ->  you go.

(See here for a complete guide of the syntax.)

Get Started

All it takes to use [x]it! is a plain text file and the text editor of your choice. The file extension is .xit. Some examples:

todo.xit for your personal tasks.
loans.xit to keep track of things that people borrowed from you.
movies.xit as a backlog of films you want to watch.
packing.xit with things you really shouldn’t forget on your next camping trip.

Tooling

You don’t have to use a specific tool for .xit files, the basic operations like creating items or checking them off can be done in every text editor.
