uair

uair is a minimal pomodoro timer for UNIX-like operating systems. Unlike other timers, uair simply prints the remaining time to standard output. Other than making the code more maintainable, this design allows uair to be very extensible as it can be used in various status bars and even command-line and graphical user interfaces.

Features

• Extensible: Can be used in status bars, desktop widgets, CLIs, GUIs, etc.
• Keyboard-driven: Uses uairctl command-line utility for pausing/resuming the timer. It can be binded to a keyboard shortcut.
• Resource-efficient: Uses concurrency instead of spawing multiple threads.

Installation

From Arch User Repository

uair is packaged for the AUR. Use an AUR helper or makepkg to install.

paru -S uair

or

yay -S uair

or

git clone https://aur.archlinux.org/uair.git
cd uair
makepkg -si

From crates.io

cargo install uair

Make sure to include $HOME/.cargo/bin in the PATH variable.

Usage

Quickstart

Copy resources/uair.toml under the project directory to ~/.config/uair/.

mkdir -p ~/.config/uair
cp -r resources/uair.toml ~/.config/uair/uair.toml

Start uair.

uair

When uair is started, or a session is completed, the timer is in a paused state. In order to start the session, uairctl command must be used. Start the session by resuming the timer by invoking uairctl from another shell.

uairctl resume

and pause the session using

uairctl pause

To toggle between pause and resume states, use

uairctl toggle

Configuration

Configuration is done in TOML. If a config file is not specified by the -c flag, it is sourced according to the XDG Base Directory Specification, i.e. it looks for the config file in the following order, until it successfully finds one.

• $XDG_CONFIG_HOME/uair/uair.toml
• $HOME/.config/uair/uair.toml
• ~/.config/uair/uair.toml

Example Config:

[defaults]
format = "{time}\n"

[[sessions]]
name = "Work"
duration = "30m"
command = "notify-send 'Work Done!'"

[[sessions]]
name = "Rest"
duration = "5m"
command = "notify-send 'Rest Done!'"

[[sessions]]
name = "Work, but harder"
duration = "1h 30m"
command = "notify-send 'Hard Work Done!'"

A list of sessions has to be provided in the sessions key. Each session is a table with the following keys:

• name: name of the session
• duration: duration of the session
• command: command which is run when the session finishes
• format: specifies the format in which text is printed each second
• autostart: boolean value (true or false) which dictates whether the session automatically starts.

If a property of a session in the array is unspecified, the default value specified in the defaults section is used instead. If the property is not mentioned in the default section too, then the property is sourced from a list of hard-coded defaults.

Integration with polybar

Include pomodoro module in the config.

[module/uair]
type = custom/script
exec = uair
label = %output%
tail = true

Remember to include the module in the modules list.

modules-right = filesystem uair pulseaudio xkeyboard memory cpu wlan eth date

In order for it to be displayed, a newline should be printed after printing the remaining time.

[defaults]
format = "{time}\n"

[[sessions]]
name = "Work"
duration = "30m"
command = "notify-send 'Work Done!'"

Simple CLI timer

[defaults]
format = "\r{time}           "

[[sessions]]
name = "Work"
duration = "1h 30m"
command = "notify-send 'Work Done!'"

Run with:

clear && uair

GUI with yad

[defaults]
format = "{percent}\n#{time}\n"

[[sessions]]
name = "Work"
duration = "1h 30m"
command = "notify-send 'Work Done!'"

Run with:

uair | yad --progress

Roadmap

• Basic pause/resume functionality using UNIX sockets
• next/prev subcommands
• Format specifiers
• Ability to reload configuration
• uairctl listen subcommand: for multiple synchonized timers
• Dedicated GUI client
• Dedicated crossterm client
