Introduction
TWC works with a concept of “agendas” influenced and borrowed from the mighty
org-mode. Agenda is basically a view of several TaskWarrior filters (called
blocks) displayed on a single screen simultaneously. You can jump between
blocks and single tasks.
To add agenda, first create a configuration file inside
~/.config/twc/config.py. It is a regular Python file with exposed variable
c which references a configuration object. You can add new blocks like that:
c.add_block(
agenda='My Agenda',
title='Next Tasks',
filter='status:pending',
sort='priority+,urgency-')

c.add_block(
agenda='My Agenda',
title='Projects',
filter='-WAITING and (+BLOCKING or +BLOCKED) and -INSTANCE',
sort='project-,priority-,order+,urgency-',
items='* description,tags:info:')


Style and colors
TWC can be styled in any way you want. To change its colors use c.set_style():
c.set_style('highlight', 'bg:ansiblue bold')
c.set_style('error', 'fg:white bg:red')
Style examples:

fg:white (white foreground, named color)
bg:#000000 (black background, hexadecimal notation)
bold italic underline blink reverse hidden (supported style flags)

Any style name can be used in task formatting. Some interface elements however
use specific style names.


Formatting
Block’s items and statusleft and statusright parameters are
composed of lists of displayed items; they can be separated by comma, which
will produce space between items, or by “+” sign, which will concatenate items
to each other without leaving space between them.
Each item can be optionally followed by a name of style which should be applied
to this item and item-specific string formatting. When style or formatting are
added, they must be separated and ended by a colon “:”: name:style:format:.
All TaskWarrior’s attribute names work as item names and there are some
additional names defined for either blocks and status line.
Example format strings are:
items = '[priority:warning:],(due:comment:%Y-%m-%d:),description'
items = '[flags::%a%s%d:]+id,description,tags:info:
Items will be only displayed when they are present. For example if there are no
tags defined for a task, tags item will not produce any output.
Items might contain additional characters in place of their names and TWC will
try to intelligently/magically (with regular expressions ;)) guess name. These
additional charactes will be printed only when item is present so they can be
used e.g. to visually delimit some items from the others (e.g. surround tags
with braces, delimit items with “|” etc.)


Key bindings
By default you can navigate with arrows or vim-style j and k. Exit TWC
with q.
You can bind and unbind keys with c.bind(key, command) and
c.unbind(key). Refer to User Manual for
a list of commands and other default key bindings.


Status line
Bottom status line displays arbitrary informations and is configurable by
two variables: statusleft and statusright. They describe format similar
to the one described in Formatting The main difference is that task
attributes are referenced by task.<attribute> placeholder and that there
additional placeholders available.
c.set('statusleft', 'COMMAND,task.id')
c.set('statusright', 'flags::%a:')
Status line items also include: taskrc, command, COMMAND,
agenda.pos, agenda.size, agenda.ppos, flags.


Installation
First, make sure that TaskWarrior is installed on your system. TaskWarrior is
packaged for most of Linux distributions. Please refer to TaskWarrior’s
documentation for details.
TWC is distributed via pypi. You can
install it with pip:
$ pip3 install --user twc
or with pip wrapper like pipsi:
$ pipsi install --python python3 twc
TWC reads your taskrc. It’ll use the default one, which is usually located
in ~/.taskrc, but you can change it with -t switch:
$ twc -t ~/dotfiles/my_taskrc


Termux
TWC works on Termux, although there’s currently a bug in tzlocal - a library
indirectly used by TWC to get local timezone information.
Before running TWC on Termux you have to export the following environment
variable:
export TZ=$(getprop persist.sys.timezone)
Termux emulates scroll events as key presses. You can bind them for easier
navigation:
c.bind('right', 'next-agenda')
c.bind('left', 'prev-agenda')
