isw

a simple terminal stopwatch application.

features:

• a basic stopwatch in a nice tui
• support for intervals
  • per-interval stopwatch colour
  • execute shell commands when intervals finish
  • counting up or down to interval boundaries
  • displaying the number of intervals or cycles elapsed
• writing the final time to stdout

installation

crates.io

the app can be installed from crates.io using the following command:

cargo install isw

if cargo is configured correctly, the command should then be available in your path.

cargo

to build the application yourself, clone the source code and run the following command:

cargo build --release

then copy/move the resulting executable at ./target/release/isw into your path.

nix

a default.nix file is available in this repo to build the application. it needs access to nixpkgs to build, which can be provided by the channel on your system (if configured) with:

nix-build -E 'with import <nixpkgs> {}; callPackage ./default.nix {}'

then copy/move the resulting executable at ./result/bin/isw into your path.

usage

a few options are available in the cli. these can be listed using the help flag:

examples

pomodoro

a typical 25 minutes on, 5 minutes off pomodoro timer that counts down to and sends a notification on interval boundaries. it also pauses to allow time to finish up tasks etc.:

isw \
  --intervals 1500,300 \
  --colours 2,1 \
  --shell 'notify-send isw "pomodoro interval complete (cycle %c)"' \
  --pause \
  --descending \
  --show-cycle

interval training

cycles of 1 minute off, 1 minute on for nasty interval training on an exercise bike:

isw \
  --intervals 60,60 \
  --colours 2,1 \
  --show-cycle

shortcut

for simple, quick, easy to read timing, clicking the clock in my system status bar launches the following command:

foot --font 'CaskaydiaCove NF:size=96' isw
