TaskWarrior's interactive terminal frontend

TWC - TaskWarrior Controller (previously TaskWarrior Curses) is interactive terminal frontend for task and TODO manager - TaskWarrior.

Features

• agendas - display several filters on a single screen simultaneously (influenced by org-mode)

• create, modify, delete, annotate tasks

• autocomplete and tab-complete writing task descriptions, annotations, tags etc.

• task formatting (with HTML-like markup)

• tasks and sub-tasks grouping (influenced by taskwiki)

• synchronize tasks with task server

• status line showing arbitrary informations

• styling

• configurable key bindings

• search and incremental search of tasks

• search can be case-sensitive, case-insensitive or smart-case (case sensitivite only when there are upper case characters in searched term)

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-',
    fmt='* {description}<info>{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')

First argument is style’s name, second one is its definition.

Style examples:

• fg:white (white foreground, named color)

• bg:#000000 (black background, hexadecimal notation)

• bg:ansiblue (blue background, ANSI color palette)

• bold italic underline blink reverse hidden (supported style flags)

• nobold noitalic noitalic (reverse flags)

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

The following styles are predefined:

• heading (default style of block headings)

• text

• comment (style used for completed and deleted tasks)

• info (default style of additional informations, like list of tags)

• warning (default style of important informations)

• error (style used when displaying error messages)

• highlight (style used for highlighting current line/task)

• tabline (style used for tab line)

• tabsel (style used for currently selected tab)

• tab (style used for not selected tabs)

• tooltip (style used for various hints and tooltips)

• statusline (style used for status line)

• status.1 (default style for some blocks in status line)

• status.2 (other default style for some blocks in status line)

Task Format

Block’s format (fmt) is a mix of Python’s string format and HTML-like markup.

You can use any TaskWarrior’s attribute name as format’s placeholder and it will be displayed if present.

*<sr left=" ["> right="] ">{id}</sr>{description}

Some additional markup can be added to the tasks. The following tags are available:

• <sr left="[", right="]>text</sr>: surrounds text with left and right.

• <ind value="A">text</ind>: if there is any text inside a tag, it will be replaced with value. It’s particularily useful for indicating that some task’s property is present, without displaying it (like long list of annotations): <sr left="[" right="]"><ind value="A">{annotations}</ind></sr>

Keep in mind that no markup will be added if above tags surround empty text (e.g. non-existent attribute).

Key bindings

You can bind and unbind keys with c.bind(key, command) and c.unbind(key).

Key can have one of the following forms:

• x (single key)

• c-x (key with modifier (ctrl) pressed)

• c x (key sequence: press c, then press x)

• space tab enter (special key names)

Below are listed all available commands

Basic controls

• activate - initiate action: enter command, show task details etc. Defaults: enter

• cancel - cancel current action. Defaults: escape

• quit - exit TWC. Defaults: q, Q, c-c

Moving around

• scroll-down - scroll down current screen/highlighted task. Defaults: down, j

• scroll-up - scroll up current screen/highlighted task. Defaults: up, k

• prev-block - jump to the previous block on current agenda. Defaults: pageup, [

• jump-begin - jump to the first line of current screen. Defaults: home, g g

• jump-end - jump to the last line of current screen. Defaults: end, G

• next-agenda - load next agenda. Defaults: tab

• prev-agenda - load previous agenda. Defaults: s-tab

Searching

• search - initiate search. Defaults: /, c-f

• find-next - finds next (forward) occurence of searched term. Defaults: n

• find-prev - finds previous (backward) occurence of searched term. Defaults: N

Controling tasks

• add-task - creates a new task. Defaults: a

• modify-task - modifies selected task. Defaults: m

• annotate - adds new annotation. Defaults: A

• denotate - removes existing annotation. Defaults: D

• toggle-completed - marks selected task as completed. Defaults: a-space

• delete-task - deletes selected task. Defaults: delete

• undo - undo last action via task undo. Defaults: u

• synchronize - synchronize with taskd sync server. Defaults: S

• refresh-agenda - reload all blocks and tasks in current agenda. Defaults: R

Command line keys

When command line is opened (input field at the bottom of the screen, used e.g. when task is being modified) some additional hard-coded key bindings are available:

• tab - open window with available completions for current word. Use tab and s-tab to jump between them.

• escape, c-c - cancel current command.

Status line

Bottom status line can display arbitrary informations and is configurable by two variables: statusleft and statusright. They describe format similar to the one described in Task Format 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', '<ind value=A>{task.annotations}</ind>')

Status line placeholders

• taskrc - path of currently used taskrc

• command - name of current command, when command line is active (e.g. add, modify, annotate,…)

• COMMAND - same as before, but command is UPPER CASED

• task.<attribute> - any attribute of currently highlighted task

• agenda.pos - position of highlighted item

• agenda.size - size of current agenda

• agenda.ppos - percentage position of highlighted item

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')
