The goal of rweekly.highlights is to create the Weekly Highlights Poll Slack Text for R Weekly editors.

This version represents a significant refactoring of the application:

• golem framework: The app now uses the golem framework for production-grade Shiny applications
• bslib UI: Modern UI components using bslib instead of shinythemes
• Split output: Poll text is now split into two sections (5 items each) for easier management
• Modular structure: Code is organized into modules and functions following golem best practices

You can install rweekly.highlights from GitHub with:

devtools::install_github("rweekly/rweekly.highlights",
                         dependencies = TRUE)

The app started by run_app() lets you pick up to 10 links from the current R Weekly draft to be voted upon by R Weekly editors.

library(rweekly.highlights)
run_app()

The draft is fetched from:

1. A local draft.md file in your working directory (if present), or
2. The remote draft from the R Weekly GitHub repository

• Checkbox interface: Select up to 10 highlights from the current draft
• Validation notifications: Visual feedback when you have selected less than, exactly, or more than 10 items
• Duplicate detection: Automatically checks for duplicate links when running from a local draft
• Split output: The 10 selected items are split into two Slack poll commands:
  • Section 1: First 5 items
  • Section 2: Second 5 items

When running from the rweekly.org repository (with _posts directory present), the app can check for duplicate links across recent issues:

# Run with duplicate checking (only works in rweekly.org repository)
run_app(check_dups = TRUE)

# Run without duplicate checking (default for development)
run_app(check_dups = FALSE)

Note: Duplicate checking requires:

• A local draft.md file in your working directory
• The _posts directory from the rweekly.org repository
• Running the app from the rweekly.org repository root

In development mode (package directory), duplicate checking is automatically skipped even if check_dups = TRUE.

This package uses Nix for reproducible environments. The default.nix file contains all required R packages and system dependencies.

When you select 10 highlights, the app generates two Slack poll commands:

Section 1 (First 5 items):

/poll "Which of the following items in R Weekly 2026-W06 should be highlighted? (Part 1)" 
"Item 1 Title
URL 1" "Item 2 Title
URL 2" ... (5 items total)

Section 2 (Second 5 items):

/poll "Which of the following items in R Weekly 2026-W06 should be highlighted? (Part 2)" 
"Item 6 Title
URL 6" "Item 7 Title
URL 7" ... (5 items total)

Copy and paste each section into the '#highlights' Slack channel.

The application follows golem's modular structure:

• R/app_ui.R - Main UI using bslib components
• R/app_server.R - Main server logic
• R/mod_highlights.R - Highlights selection module
• R/fct_parse_draft.R - Draft parsing functions
• R/fct_slack_format.R - Slack poll formatting functions
• R/dup.R - Duplicate link detection utilities
• inst/golem-config.yml - Application configuration
