v0.3.0

What's new

• Named code blocks — Add metadata to code fences with ```bash name="setup" syntax; block names are displayed in the TUI header and can be referenced with --blocks setup,cleanup
• Process cancellation — Press Ctrl+C to cancel a running block in the TUI instead of killing the app; the focused block's process is terminated and the TUI stays open
• Execution timeout — New --timeout <seconds> flag for the headless runner to kill blocks that exceed a time limit
• Parallel execution — New --parallel flag for the headless runner to execute all blocks concurrently; supports --fail-fast to cancel remaining blocks on first failure
• Separate stderr display — stderr output now renders in a distinct red-bordered section below stdout, instead of being mixed together
• Improved .env parser — Supports export prefix, multiline quoted values, and escaped quotes (\", \') inside values

Bug fixes

• Focus preserved across mode transitions — Switching between normal and insert mode no longer loses the focused block position

See CHANGELOG for full details.

v0.2.0

Features

• Streaming output — Command stdout/stderr now streams in real-time as it's produced, instead of buffering until completion
• Headless runner — New runmd run <file.md> command for non-interactive execution with --fail-fast and --blocks flags
• Syntax-highlighted output — Command output is now syntax-highlighted using tree-sitter (auto-detects JSON)
• JSON pretty-printing — JSON responses are automatically formatted with indentation for readability

Security

• Environment variables hidden in UI — ${VAR_NAME} placeholders are now displayed as-is in code blocks instead of showing substituted values; variables are only resolved at execution time
