A shell bot for Slack. A demo is worth a thousand words.
This bot is built with slack-ruby-bot-server-events. See CONTRIBUTING.
The website follows the shared Slava, Strata, and Strada layout with a terminal-inspired black/charcoal palette (base #303035). The editable public/img/screenshot-background.svg adapts the shared ribbon artwork and keeps preserveAspectRatio="none" on a fixed viewport-sized layer so expanding help does not resize the background. Preserve the original transparent public/img/icon.png terminal logo, its matching multi-resolution favicon, and the original public/img/shell.gif demonstration when updating the design.
The bot recommendations use local copies of the original logos: bot-slava.png and bot-strada.png from their respective projects' public/img/icon.png, bot-gamebot.png from slack-gamebot2's public/img/game.png, and bot-sup.png from slack-sup2's public/img/icon.png. Preserve their original colors rather than applying the Shell website's monochrome styling.
The website uses rack-server-pages 0.3.0's asset_path helper for content-versioned CSS, JavaScript, images, and favicon URLs. Use the helper for new local asset references rather than fixed URLs or manual version strings. public/styles.css.erb is served at /styles.css and versions the background image reference too.
The config.server_pages block in config/initializers/slack_ruby_bot_server.rb, supported by slack-ruby-bot-server 2.3.0, sets Cache-Control: private, no-cache for templates, including HTML and the generated stylesheet, requiring revalidation before reuse. This lets the stylesheet pick up a changed background image even when its own source is unchanged. Static files use the library's default content-based ETag and timestamp validation. Versioned URLs serve current files rather than archived versions; do not add immutable or long freshness lifetimes. Existing cached pages need to fetch fresh HTML before they can use the new URLs.
