Overview

About

Maintained by Garrick Aden-BuieCRAN page ↗GitHub ↗Website ↗Issues ↗

A simple countdown timer for slides and HTML documents written in 'R Markdown' or 'Quarto'. Integrates fully into 'Shiny' apps. Countdown to something amazing.

Changes in 0.6.0

Breaking changes

The first countdown() timer no longer provides global styles for all other countdown timers. Instead, use countdown_style() with the same style-related arguments to set global styles for all countdown timers. (#36)

New features and improvements

The countdown JavaScript implementation was entirely re-written as a custom <countdown-timer> element. This improves lifecycle management of the timer component, making it possible to use countdown timers with dynamic UI in Shiny apps. (#59)
Rewritten countdown timer CSS now uses CSS variables rather than a template rendered in R. This improves how countdown's dependencies are handled and makes it easier to customize and use countdown in other projects and settings. (#36)

Implemented emitting of native browser events alongside Shiny communication. (#37)
Added two new event types: "finished" when the timer completes its cycle and "warning" when it reaches the warning period. (#37)
Set class = "inline" in countdown() to create an inline, rather than absolute-positioned, countdown timer. (#36)
Set class = "no-controls" in countdown() to create a countdown timer without the controls. (#40)

Bug fixes

Fixed an issue where custom URLs for play_sound were not used for the timer end sound. (thanks @jannismain, #38)
Fixed countdown_fullscreen() not passing along class and start_immediately parameters. (#43)

Changes

Switched to using {bslib} to stylize the demo countdown shiny app. (#37)
Clarified play_sound documentation to emphasize custom sounds require the countdown clock to be embedded in a website, presentation, or Shiny app to be played due to JavaScript limitations on local files. (#44)

From NEWS.md in the release

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("countdown", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("gadenbuie/countdown")

Development version from gadenbuie/countdown. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-countdown

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-countdown

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-countdown

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
