    "text": "Excellent! I have the complete section 4.4 on indented code blocks. Let me compile the detailed findings:\n\n## GFM Specification Section 4.4: Indented Code Blocks\n\n### 1. Exact Rules for What Constitutes an Indented Code Block\n\n**Core Definition:**\n- An indented code block is composed of one or more **indented chunks** separated by blank lines\n- An **indented chunk** is a sequence of non-blank lines, each indented **four or more spaces**\n- The contents are the literal contents of the lines (including trailing line endings), **minus four spaces of indentation**\n- An indented code block has **no info string** (unlike fenced code blocks)\n\n### 2. How They Start and End\n\n**Starting:**\n- A line indented with 4+ spaces begins an indented code block\n- Can start after any block-level element\n\n**Ending:**\n- Blank lines separate chunks but don't end the code block (they're preserved in the output)\n- The code block ends when a **non-blank line with fewer than four leading spaces** is encountered\n- Blank lines preceding or following an indented code block are **not included** in the block\n\n**Critical Constraint:**\n- **An indented code block cannot interrupt a paragraph** - there must be a blank line between a paragraph and a following indented code block\n- However, no blank line is needed between a code block and a following paragraph\n\n### 3. Edge Cases and Examples\n\n**Example 77 (Basic indented code block):**\n```\n    a simple\n      \n     indented code block\n```\nOutput preserves the extra spaces beyond 4:\n```html\n<pre><code>a simple\n              indented code block\n            </code></pre>\n```\n\n**Example 78 & 79 (List precedence):**\nLists take precedence over indented code block interpretation. When indentation is ambiguous, list item interpretation wins:\n```\n-\n      foo\n\n         bar\n```\nThis creates a list item with two paragraphs (foo and bar), NOT a code block.\n\n**Example 80 (Literal text - no markdown parsing):**\n```\n    <a/>\n      \n    *hi*\n\n      \n    - one\n```\nHTML, emphasis, and list syntax are all treated as literal text inside the code block.\n\n**Example 81 (Multiple chunks separated by blank lines):**\nThree chunks separated by blank lines are combined into one code block:\n```\n    chunk1\n\n      \n    chunk2\n     \n     \n     \n      \n    chunk3\n```\nOutput includes the blank lines:\n```html\n<pre><code>chunk1\n\nchunk2\n\n\n\nchunk3\n            </code></pre>\n```\n\n**Example 82 (Interior blank lines preserve extra spaces):**\nAny spaces beyond the initial 4 are preserved, even on blank lines:\n```\n    chunk1\n      \n     \n      \n     chunk2\n```\nThe interior blank line retains 2 extra spaces beyond the 4 removed.\n\n**Example 83 (Cannot interrupt paragraphs):**\n```\nFoo\n      bar\n```\nThis becomes a single paragraph, not a code block, because the indented line follows the paragraph without a blank line separator.\n\n**Example 84 (Paragraph after code block):**\nA line with fewer than 4 spaces immediately ends the code block:\n```\n    foo\nbar\n```\nOutput:\n```html\n<pre><code>foo\n</code></pre>\n<p>bar</p>\n```\n\n**Example 85 (Adjacent to other block types):**\nIndented code can occur before/after headings and other blocks without blank lines needed in one direction:\n```\n# Heading\n      foo\nHeading\n------\n      foo\n----\n```\nProduces heading, code block, heading, code block, horizontal rule.\n\n**Example 86 (First line indented more than 4 spaces):**\nExtra indentation on the first line is preserved:\n```\n        foo\n      bar\n```\nOutput has 1 space before \"foo\" (8 - 4 = 4 leading spaces including the preserved 1):\n```html\n<pre><code> foo\nbar\n            </code></pre>\n```\n\n**Example 87 (Surrounding blank lines excluded):**\nBlank lines before and after a code block are not included:\n```\n      \n       foo\n      \n```\nOutput contains only the \"foo\" line.\n\n**Example 88 (Trailing spaces preserved):**\n```\n    foo  \n```\nTrailing spaces are included in the code block's content.\n\n### 4. Interaction with Other Block Types\n\n**With Paragraphs:**\n- Indented code **cannot interrupt** a paragraph - requires a blank line before it\n- No blank line needed **after** a code block before a paragraph\n\n**With Lists:**\n- **List interpretation takes precedence** over code block interpretation when ambiguous\n- List items can contain indented text that would otherwise be code blocks\n\n**With Other Blocks (Headings, Thematic breaks):**\n- No blank line required between indented code and other block types\n- Can occur immediately before or after headings without blank line separation\n\n**With Blank Lines:**\n- Multiple blank lines between chunks are preserved as part of the code block content\n- Blank lines at the start and end of the block are stripped"

Let me create a detailed summary document.\n\n## Detailed Findings: Streaming Markdown Parser Architecture\n\nBased on my examination of `/Users/llimllib/code/mdriver/features/src/lib.rs`, here's a comprehensive analysis of the current streaming parser implementation:\n\n---\n\n### 1. CORE DATA STRUCTURES\n\n**StreamingParser (Lines 101-118)**\n```\npub struct StreamingParser {\n    buffer: String,                          // Accumulates incomplete blocks\n    state: ParserState,                      // Current parsing state\n    current_block: BlockBuilder,             // Builds block content incrementally\n    syntax_set: SyntaxSet,                   // For syntax highlighting\n    theme_set: &'static EmbeddedLazyThemeSet,\n    theme_name: String,\n    image_protocol: ImageProtocol,\n    width: usize,\n    image_cache: HashMap<String, Vec<u8>>,\n    link_definitions: HashMap<String, (String, Option<String>)>,\n    pending_citations: RefCell<Vec<(usize, String, String)>>,\n    next_citation_number: RefCell<usize>,\n}\n```\n\n**ParserState Enum (Lines 128-142)**\n- **Ready**: Not currently parsing any block\n- **InParagraph**: Accumulating paragraph lines (terminated by blank line)\n- **InCodeBlock**: Inside a fenced code block (with `info`, `fence` string, and `indent_offset`)\n- **InList**: Accumulating list items\n- **InListAfterBlank**: Special state for handling blank lines within lists\n- **InTable**: Building table rows\n- **InBlockquote**: Inside blockquote (tracks nesting level)\n\n**BlockBuilder Enum (Lines 144-167)**\nContains the accumulated content for each block type:\n- **Paragraph**: `Vec<String>` of lines\n- **CodeBlock**: `Vec<String>` of code lines plus language `info` string\n- **List**: `Vec<(usize, ListItemType, String)>` tuples (indentation level, type, raw content)\n- **Table**: Header cells, alignment info, and body rows\n- **Blockquote**: `Vec<(usize, String)>` tuples (nesting level, content)\n\n---\n\n### 2. STATE MACHINE FLOW\n\n**Main Entry Point: `pub fn feed(&mut self, chunk: &str) -> String` (Lines 346-362)**\n\n```\n1. Append chunk to internal buffer\n2. Loop while buffer contains complete lines (find '\\n'):\n   - Extract line (including newline)\n   - Call process_line()\n   - Remove line from buffer\n3. Return accumulated output\n```\n\n**Line Processing: `fn process_line(&mut self, line: &str) -> Option<String>` (Lines 430-440)**\n\nDispatches based on current state:\n```rust\nmatch &self.state {\n    ParserState::Ready => self.handle_ready_state(line),\n    ParserState::InParagraph => self.handle_in_paragraph(line),\n    ParserState::InCodeBlock { .. } => self.handle_in_code_block(line),\n    ParserState::InList => self.handle_in_list(line),\n    ParserState::InListAfterBlank => self.handle_in_list_after_blank(line),\n    ParserState::InTable => self.handle_in_table(line),\n    ParserState::InBlockquote { .. } => self.handle_in_blockquote(line),\n}\n```\n\n---\n\n### 3. DETAILED STATE HANDLERS\n\n#### **3.1 Ready State Handler: `fn handle_ready_state(&mut self, line: &str)` (Lines 442-520)**\n\nWhen a line arrives and parser is ready, checks in this order:\n1. **Blank line** (line 446) → Return None (no emission)\n2. **HTML comments** (line 452) → Silently skip\n3. **ATX headings** (line 457) → **Emit immediately** (headings complete on single line!)\n4. **Code fence** (line 464) → **Transition to InCodeBlock state**, return None\n5. **Blockquote** (line 478) → Transition to InBlockquote state\n6. **Horizontal rule** (line 490) → **Emit immediately**\n7. **List item** (line 495) → Transition to InList state\n8. **Link reference definition** (line 505) → Store in `link_definitions` HashMap, don't emit\n9. **Otherwise** → Transition to InParagraph state\n\n**Key Pattern**: Most blocks transition to a state and return None. Only \"atomic\" blocks (headings, rules) emit immediately.\n\n#### **3.2 Code Block Handler: `fn handle_in_code_block(&mut self, line: &str)` (Lines 566-599)**\n\n```\n1. Check if line is closing fence:\n   - Must match exact fence string (``` or ~~~)\n   - Can have 0-3 leading spaces (normal) or 4+ (inside list)\n   - Line must be just the fence (possibly with trailing spaces)\n   - YES → Emit entire block via emit_current_block()\n2. Otherwise:\n   - Add line to BlockBuilder::CodeBlock.lines\n   - Strip indent_offset spaces from beginning (for nested code blocks)\n   - Return None (no emission yet)\n```\n\n**Code Fence Parsing: `fn parse_code_fence(&self, line: &str)` (Lines 888-909)**\n- Returns `Option<(String, String, usize)>` = (language info, fence string, leading spaces)\n- Only `\\`\\`\\`` or `~~~` recognized\n- 0-3 spaces of indentation allowed\n- Extracts language info from after fence\n\n#### **3.3 Paragraph Handler: `fn handle_in_paragraph(&mut self, line: &str)` (Lines 522-564)**\n\n```\n1. If blank line → Emit current block, return to Ready\n2. If setext underline (=== or ---) → Convert to heading, emit\n3. If table delimiter row → Promote paragraph to table, continue\n4. Otherwise → Append line to paragraph buffer\n```\n\n#### **3.4 List Handler: `fn handle_in_list(&mut self, line: &str)` (Lines 601-...)**\n\n- Blank line → Transition to InListAfterBlank\n- Horizontal rule → Emit list + rule\n- Another list item → Append to list buffer\n- Indented content (4+ spaces) → Check for code fence, otherwise append\n\n#### **3.5 Blockquote Handler**\n- Tracks nesting levels (number of `>` markers)\n- Can contain nested structures\n\n---\n\n### 4. BLOCK EMISSION\n\n**Primary Function: `fn emit_current_block(&mut self) -> Option<String>` (Lines 1106-1131)**\n\n```rust\n1. Extract block content via mem::replace() (moves BlockBuilder::current_block out)\n2. Reset state to Ready and current_block to None\n3. If images enabled: prefetch all image URLs in parallel\n4. Match on block type and call appropriate formatter:\n   - BlockBuilder::Paragraph → format_paragraph()\n   - BlockBuilder::CodeBlock → format_code_block()\n   - BlockBuilder::List → format_list()\n   - BlockBuilder::Table → format_table()\n   - BlockBuilder::Blockquote → format_blockquote()\n```\n\n---\n\n### 5. FENCED CODE BLOCK IMPLEMENTATION (Reference for New Block Types)\n\n**Parsing (Lines 464-475 in handle_ready_state)**:\n```rust\nif let Some((info, fence, indent_offset)) = self.parse_code_fence(trimmed) {\n    self.state = ParserState::InCodeBlock {\n        info: info.clone(),\n        fence: fence.clone(),\n        indent_offset,\n    };\n    self.current_block = BlockBuilder::CodeBlock {\n        lines: Vec::new(),\n        info,\n    };\n    return None;\n}\n```\n\n**Accumulation (Lines 587-595 in handle_in_code_block)**:\n```rust\nif let BlockBuilder::CodeBlock { lines, .. } = &mut self.current_block {\n    let line_to_add = if *indent_offset > 0 && trimmed.len() >= *indent_offset {\n        &trimmed[*indent_offset..]\n    } else {\n        trimmed\n    };\n    lines.push(line_to_add.to_string());\n}\n```\n\n**Emission (Lines 1230-1280 - format_code_block)**:\n- Uses syntect for syntax highlighting\n- Applies 4-space indentation\n- Gets theme from two-face\n- Returns highlighted lines with ANSI codes\n\n---\n\n### 6. INLINE FORMATTING PIPELINE\n\n**Entry Point: `pub fn format_inline(&self, text: &str)` (Lines 2008+)**\n\nProcesses inline markdown in this order:\n1. `![alt](src)` images (line 2015)\n2. `[text](url)` links (line 2026)\n3. `[text][ref]` reference links (line 2043)\n4. `~~strikethrough~~` (line 2051)\n5. `**bold**` (line 2064)\n6. `*italic*` (line 2077)\n7. `` `code` `` (line 2090)\n8. `__bold__` underscore variant (line 2101)\n9. `_italic_` underscore variant (line 2114)\n10. `<html>` tags (line 2126)\n\nEach formatter:\n- Wraps with ANSI codes (e.g., `\\u{001b}[1m` for bold)\n- Recursively calls format_inline for nested content\n- Resets with `\\u{001b}[0m`\n\n---\n\n### 7.

ARCHITECTURE PATTERNS FOR ADDING NEW BLOCK TYPES\n\nTo add a new block type (e.g., \"Admonition\" or \"Details\"):\n\n**Step 1: Add to ParserState enum (after line 142)**\n```rust\nInAdmonition {\n    admonition_type: String,  // e.g., \"note\", \"warning\"\n    lines: Vec<String>,\n},\n```\n\n**Step 2: Add to BlockBuilder enum (after line 167)**\n```rust\nAdmonition {\n    admonition_type: String,\n    lines: Vec<String>,\n},\n```\n\n**Step 3: Add parser function (example at line 790+)**\n```rust\nfn parse_admonition_marker(&self, line: &str) -> Option<String> {\n    // Return admonition type if detected\n}\n```\n\n**Step 4: Add handler in handle_ready_state (after line 442)**\n```rust\nif let Some(admonition_type) = self.parse_admonition_marker(trimmed) {\n    self.state = ParserState::InAdmonition { admonition_type: admonition_type.clone() };\n    self.current_block = BlockBuilder::Admonition {\n        admonition_type,\n        lines: Vec::new(),\n    };\n    return None;\n}\n```\n\n**Step 5: Add state handler (e.g., handle_in_admonition)**\n```rust\nfn handle_in_admonition(&mut self, line: &str) -> Option<String> {\n    let trimmed = line.trim_end_matches('\\n');\n    \n    // Blank line or block terminator -> emit\n    if trimmed.is_empty() || /* other terminator */ {\n        return self.emit_current_block();\n    }\n    \n    // Accumulate\n    if let BlockBuilder::Admonition { lines, .. } = &mut self.current_block {\n        lines.push(trimmed.to_string());\n    }\n    None\n}\n```\n\n**Step 6: Add dispatch in process_line (after line 440)**\n```rust\nParserState::InAdmonition { .. } => self.handle_in_admonition(line),\n```\n\n**Step 7: Add formatter in emit_current_block (after line 1131)**\n```rust\nBlockBuilder::Admonition { admonition_type, lines } => \n    Some(self.format_admonition(&admonition_type, &lines)),\n```\n\n**Step 8: Implement formatter function**\n```rust\nfn format_admonition(&self, admonition_type: &str, lines: &[String]) -> String {\n    let styled_type = format!(\"\\u{001b}[1m{}\\u{001b}[0m\", admonition_type);\n    let content = self.format_inline(&lines.join(\" \"));\n    format!(\">>> {} {}\\n\\n\", styled_type, content)\n}\n```\n\n---\n\n### 10. KEY STREAMING BEHAVIORS\n\n1. **Immediate Emission**: Atomic blocks (headings, rules) emit in `handle_ready_state` immediately\n2. **Buffering**: Multi-line blocks accumulate in `BlockBuilder` until completion signal\n3. **Completion Signals**:\n   - Headings: After the `#` line itself (immediate)\n   - Paragraphs: After blank line (`\\n\\n`)\n   - Code blocks: After matching closing fence\n   - Lists: After blank line or different block type\n   - Blockquotes: After blank line or exited nesting\n\n4. **State Transitions**: Each handler can transition to a new state or emit and return to Ready\n\n5. **Partial Chunks**: The buffer accumulates until a complete line (`\\n` found), then processes\n\n---\n\n### 11. IMPORTANT IMPLEMENTATION DETAILS\n\n- **ANSI Codes**: All formatting uses `\\u{001b}` escape sequences (never `\\x1b`)\n- **Color Codes**:\n  - Bold: `\\u{001b}[1m`\n  - Italic: `\\u{001b}[3m`\n  - Strikethrough: `\\u{001b}[9m`\n  - Blue heading: `\\u{001b}[1;34m`\n  - Code background: `\\u{001b}[48;5;235m`\n  - Reset: `\\u{001b}[0m`\n\n- **Double Newlines**: Most block types end with `\\n\\n` for spacing\n\n- **Text Wrapping**: The `wrap_text` function handles line-wrapping with proper indentation for continuations\n\n- **Image Handling**: Code supports parallel prefetching via `prefetch_images()`, uses OSC 8 hyperlinks\n\n- **Link References**: Stored in `link_definitions` HashMap, rendered at flush time if citations are pending\n\n---\n\nThis architecture makes adding new block types straightforward: define state, builder, parser, handler, and formatter, then wire them together in the dispatch points."
