cl-bbs
An anonymous textboard (BBS) engine written in Common Lisp. It is a high-performance, modern clone of the original MIT Scheme SchemeBBS (which ran behind dis.4chan.org and world4ch /prog/).
Features
Seamless SchemeBBS Layout: Displays threads, index lists, and posts inside definition lists (, , ) exactly conforming to the original SchemeBBS style.
Single Trailing Forms: Conforms to the original textboard paradigm where a single posting form is rendered at the very end of the thread (no per-post forms).
Comprehensive Formatting Support:
Bold: **text** -> text
Italic: __text__ -> text
Monospace: `text` -> text (Uses the standard backtick notation)
Spoilers: ~~text~~ -> text
Blockquotes: Lines starting with > are rendered as blocks.
Post References: >>7 are dynamically hyperlinked to jump anchors inside the thread page.
Direct Image Link Previews: Direct links to images (.png, .jpg, .jpeg, .gif, .webp, .bmp) are automatically converted into elegant clickable image previews.
Standard URLs: Standard URLs are automatically formatted as standard hyperlinks.
Dynamic Board Headers: Centered and left-aligned board listing headers (e.g. [ foo | prog ]) are scanned and displayed dynamically at the top of every page.
Theme Preferences (Cookies): Choose between multiple themes (default, classic, dark, mona, no) on the /board/preferences page. Selections are stored inside browser cookies (theme) and persistent.
Zero JavaScript Required: The application is completely server-rendered.
Local Qlot Sandbox: Locked sandbox dependencies pinned via qlfile to ensure backwards compatibility across environments.
29-Assertion Test Suite: Comprehensive test coverage verifying cookies, routing pipelines, and formatting rules.
