feat: replace marked-terminal with custom terminal renderer - #696
Merged
Conversation
Replace marked-terminal with a custom TerminalRenderer extending marked.Renderer. Add proposal, design, specs, and tasks for the change. See issue #595 for full details.
Replace the unmaintained marked-terminal dependency with a custom TerminalRenderer class extending marked.Renderer. Upgrades marked from 9.1.6 to 15.x, enabling security fixes and new markdown features. The custom renderer implements all markdown elements with ANSI styling via chalk, syntax highlighting via cli-highlight, table rendering via cli-table3, emoji support via node-emoji, and hyperlink support via supports-hyperlinks. BREAKING: Renders output uses different ANSI sequences than marked-terminal. Visual output is parity-equivalent.
Archive the change and sync terminal-renderer spec delta to main.
