Add pairing detection for system command+output, tool use+result, bash input+output - Implement TemplateMessage pairing metadata (is_paired, pair_role, tool_use_id) - Create _identify_message_pairs() function for automatic pair detection - Style paired messages with continuous borders and reduced spacing **Color Scheme Refinements:** - System command output: dimmed red border (#f4433666) matching system - Tool use: green border (#4caf50) - Tool result: dimmed green border (#4caf5066) - User: orange border (#ff9800) - System: red border (#f44336) **Tool Message Improvements:** - Simplify display: "Tool Use: Grep" and "Tool Result" (no inline IDs) - Add hover tooltips showing tool IDs via title attribute - Merge tool_use and tool_result filters into single "Tool" button - Green border (#4caf50) on unified tool filter button - Update JavaScript to handle combined tool filtering **Template Enhancements:** - Add title_hint field to TemplateMessage for hover tooltips - Update template to render paired-message CSS classes - Modify filter JavaScript to expand "tool" type to both tool_use and tool_result - Update message counts to combine tool types 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- claude_code_log/renderer.py | 84 +++++++++++++++++-- .../templates/components/filter_styles.css | 5 ++ .../templates/components/message_styles.css | 32 ++++++- claude_code_log/templates/transcript.html | 43 +++++++--- 4 files changed, 146 insertions(+), 18 deletions(-) diff --git a/claude_code_log/renderer.py b/claude_code_log/renderer.py index 74de37fd..3bc575ed 100644 --- a/claude_code_log/renderer.py +++ b/claude_code_log/renderer.py @@ -564,6 +564,8 @@ def __init__( session_id: Optional[str] = None, is_session_header: bool = False, token_usage: Optional[str] = None, + tool_use_id: Optional[str] = None, + title_hint: Optional[str] = None, ): self.type = message_type self.content_html = content_html @@ -576,6 +578,11 @@ def __init__( self.is_session_header = is_session_header self.session_subtitle: Optional[str] = None self.token_usage = token_usage + self.tool_use_id = tool_use_id + self.title_hint = title_hint + # Pairing metadata + self.is_paired = False + self.pair_role: Optional[str] = None # "pair_first", "pair_last", "pair_middle" class TemplateProject: @@ -1128,6 +1135,62 @@ def _get_combined_transcript_link(cache_manager: "CacheManager") -> Optional[str return None +def _identify_message_pairs(messages: List[TemplateMessage]) -> None: + """Identify and mark paired messages (e.g., command + output, tool use + result). + + Modifies messages in-place by setting is_paired and pair_role fields. + """ + i = 0 + while i < len(messages): + current = messages[i] + + # Skip session headers + if current.is_session_header: + i += 1 + continue + + # Check for system command + command output pair + if current.css_class == "system" and i + 1 < len(messages): + next_msg = messages[i + 1] + if "command-output" in next_msg.css_class: + current.is_paired = True + current.pair_role = "pair_first" + next_msg.is_paired = True + next_msg.pair_role = "pair_last" + i += 2 + continue + + # Check for tool_use + tool_result pair (match by tool_use_id) + if current.css_class == "tool_use" and current.tool_use_id: + # Look ahead for matching tool_result + for j in range( + i + 1, min(i + 10, len(messages)) + ): # Look ahead up to 10 messages + next_msg = messages[j] + if ( + next_msg.css_class == "tool_result" + and next_msg.tool_use_id == current.tool_use_id + ): + current.is_paired = True + current.pair_role = "pair_first" + next_msg.is_paired = True + next_msg.pair_role = "pair_last" + break + + # Check for bash-input + bash-output pair + if current.css_class == "bash-input" and i + 1 < len(messages): + next_msg = messages[i + 1] + if next_msg.css_class == "bash-output": + current.is_paired = True + current.pair_role = "pair_first" + next_msg.is_paired = True + next_msg.pair_role = "pair_last" + i += 2 + continue + + i += 1 + + def generate_session_html( messages: List[TranscriptEntry], session_id: str, @@ -1474,6 +1537,8 @@ def generate_html( # Handle both custom types and Anthropic types item_type = getattr(tool_item, "type", None) + item_tool_use_id: Optional[str] = None + tool_title_hint: Optional[str] = None if isinstance(tool_item, ToolUseContent) or item_type == "tool_use": # Convert Anthropic type to our format if necessary @@ -1490,10 +1555,12 @@ def generate_html( tool_content_html = format_tool_use_content(tool_use_converted) escaped_name = escape_html(tool_use_converted.name) escaped_id = escape_html(tool_use_converted.id) + item_tool_use_id = tool_use_converted.id + tool_title_hint = f"ID: {escaped_id}" if tool_use_converted.name == "TodoWrite": -

Subject: [PATCH 27/50] Simplify tool message display headers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Changes:
- Remove "Tool Use:" prefix from tool names (e.g., "Bash" instead of "Tool Use: Bash")
- Remove "Tool Result" heading entirely for normal tool results
- Only show "🚨 Error" heading for error tool results
- Hide header div completely when message type is empty

This creates a cleaner, more focused display where specialized tools
like Bash and TodoWrite have minimal chrome, letting the content speak
for itself.

This makes tool parameters much more readable while still showing
the full structure when needed.

Updated test expectations to match new table format.

Subject: [PATCH 31/50] Add key/value table rendering for tool parameters with
 collapsible long values
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Replace inline styles with CSS classes for tool parameter tables
- Render tool parameters as clean key/value tables instead of raw JSON
- Add collapsible details for long string values (>100 chars) and structured values (>200 chars)
- Use 80% font-size for compact display
- Fixed 8em width for parameter keys
- Subtle border styling with #4b494822 for table rows
- Add local config files to .gitignore

Subject: [PATCH 33/50] Add IDE notification preprocessing for user messages
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement preprocessing for IDE-specific tags like  that
appear in user messages when working in the Claude Code VS Code extension.

Key changes:
- Add extract_ide_notifications() to separate IDE tags from regular content
- Render IDE notifications with distinctive styling and bot icon prefix
- Move user-specific preprocessing out of render_message_content() into
  _process_regular_message() to avoid affecting assistant messages
- Update CSS styling for .ide-notification per user feedback
- Fix toggle functionality tests to match tool parameter table format
- Add comprehensive test coverage for IDE tag extraction

The preprocessing cleanly separates special IDE notifications from regular
user content, rendering them first with distinctive styling while preserving
the normal preformatted display for remaining text.

Subject: [PATCH 34/50] Refactor user message preprocessing for cleaner
 architecture
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extract render_user_message_content() function to handle user-specific
preprocessing (IDE tags and compacted summaries) separately from generic
message rendering. Key improvement: normalize string input to list form
immediately to eliminate code duplication.

Changes:
- Add render_user_message_content() that returns (content_html, is_compacted)
- Simplify _process_regular_message() from 95 lines to 30 lines
- Convert string to list early: [TextContent(type="text", text=...)]
- Eliminate all duplication between string and list handling paths
- Add comprehensive test coverage for IDE tag extraction

All tests pass (235 passed).

Subject: [PATCH 35/50] Push normalization to data extraction layer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Major refactoring to eliminate Union types and normalize content to
List[ContentItem] at the earliest point in the pipeline.

Key changes:
- render_user_message_content() now takes List[ContentItem] only
- render_message_content() now takes List[ContentItem] only
- String content normalized to [TextContent(...)] at extraction (line 1284)
- Removed all Union[str, List[ContentItem]] type annotations
- Fixed isinstance bug: content[0] instead of content (line 554)
- Simplified control flow by eliminating string/list branching

Test coverage:
- Added test_render_user_message_with_multi_item_content()
- Added test_render_message_content_single_text_item()
- Added test_render_message_content_single_text_item_assistant()

All 238 tests pass.

Subject: [PATCH 36/50] Add IDE diagnostics rendering with table reuse
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement clean rendering of post-tool-use-hook IDE diagnostics
by extracting and reusing table rendering logic.

Key changes:
- Extract render_params_table() from format_tool_use_content()
  for reusable key-value table rendering
- Extend extract_ide_notifications() to handle two patterns:
  1. : Simple file open notifications (existing)
  2. : JSON diagnostic arrays (new)
- Parse JSON diagnostic arrays and render each as a table
- Graceful fallback for JSON parse errors

Test coverage:
- Add test_extract_ide_diagnostics(): JSON parsing and table rendering
- Add test_extract_mixed_ide_tags(): Both tag types together

All 240 tests pass.

Subject: [PATCH 38/50] Fix compacted summary markdown rendering regression
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When rendering compacted session summaries, pass "assistant" instead of
"user" to render_message_content() to trigger markdown rendering instead
of HTML-escaped preformatted text.

The regression was introduced during refactoring when the logic was
simplified - compacted summaries are user messages but need markdown
rendering like assistant messages.

Subject: [PATCH 41/50] Fix sidechain (sub-assistant) rendering issues
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit addresses four issues with sub-assistant message rendering:

1. **Sub-assistant Prompt markdown rendering**: Modified _process_regular_message()
   to render sidechain user messages as markdown instead of preformatted text.
   Sidechain user messages are sub-assistant prompts and should be formatted
   like assistant messages.

2. **Sidechain filter logic**: Simplified the filter JavaScript in transcript.html
   to use simple OR matching. Previously required BOTH sidechain AND message type
   filters to be active, causing the sidechain filter to show (0/135) and not work.
   Now clicking sidechain filter correctly shows all sidechain messages.

3. **Sidechain indentation**: Added margin-left: 4em to .sidechain CSS class to
   nest sub-assistant messages below the Task tool use that triggered them,
   following the existing indentation pattern for nested messages.

4. **Tool pairing for sidechain**: Fixed _identify_message_pairs() to use
   "in" checks instead of exact equality for CSS class matching. Sidechain
   messages have classes like "tool_use sidechain" (space-separated), so
   exact equality checks failed. Now tool_use/tool_result and thinking/assistant
   pairs work correctly for sidechain messages.

All unit tests pass (244 passed).

Subject: [PATCH 42/50] Refine sidechain indentation hierarchy
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Updated sidechain CSS to properly reflect the nesting hierarchy:

- Sub-assistant Prompt (.sidechain.user): 3em
  Nested below Task tool use (2em)

- Sub-assistant (.sidechain.assistant): 4em
  Nested below Sub-assistant Prompt (3em)

- Sub-assistant tools (.sidechain.tool_use, .sidechain.tool_result): 5em
  Nested below Sub-assistant (4em)

This creates a clear visual hierarchy showing the relationship between:
Task → Sub-assistant Prompt → Sub-assistant → Sub-assistant Tools

Previous implementation used a flat 4em for all sidechain messages.

Subject: [PATCH 43/50] Add specialized diff rendering for Edit tool
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implemented character-level diff highlighting for the Edit tool to make
code changes more visible and easier to review.

**Features:**
- File path header with emoji indicator
- Line-level diff (added/removed/context lines)
- Character-level highlighting within changed lines using difflib.SequenceMatcher
- GitHub-style color scheme (green for additions, red for deletions)
- Monospace font with proper line wrapping
- Support for "replace_all" indicator

**Implementation:**
- Added `format_edit_tool_content()` function in renderer.py
- Added `_render_line_diff()` helper for intra-line diff highlighting
- Created new `edit_diff_styles.css` component with GitHub-inspired colors
- Updated `format_tool_use_content()` to route Edit tool to specialized renderer
- Updated test expectations to match new diff rendering

**Visual Design:**
- Inter-line changes: Full background color on added/removed lines
- Intra-line changes: Highlighted with darker background on specific characters
- Context lines: Neutral background for unchanged content
- Diff markers: "-" for removed, "+" for added, " " for context

Subject: [PATCH 44/50] CSS improvements: standardize colors and merge
 duplicates
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit addresses visual consistency improvements:

1. Edit diff styling tweaks:
   - Changed .edit-diff font-size from 0.85em to 80% for consistency
   - Changed .diff-context background to #f5f1e8 (matching code blocks)

2. Removed duplicate code background color definition:
   - Removed duplicate from global_styles.css (#f5f5f5)
   - Kept single definition in message_styles.css (#f5f1e8)
   - This consolidates "Common typography" and "Code block styling" sections

3. Standardized border colors:
   - Changed .bash-tool-command border to #4b494822
   - Now matches .tool-params-table tr border color
   - Ensures visual consistency across tool-related elements

All tests pass (243 passed).

Subject: [PATCH 45/50] Introduce CSS variables for shared colors and theming
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit establishes a centralized color system using CSS custom
properties (variables) to facilitate future theming and maintain
consistency across styles.

Changes:

1. Added :root variables in global_styles.css:
   - Base colors: --code-bg-color, --tool-param-sep-color
   - Dimmed variants (66 = ~40% opacity): Various semantic colors
   - Semi-transparent variants (88 = ~53% opacity): Highlights, errors
   - Light variants (55 = ~33% opacity): Subtle backgrounds
   - Text colors: --text-muted (#666), --text-secondary (#495057)

2. Updated message_styles.css to use variables:
   - Message borders and backgrounds
   - System message variants (warning, error, info)
   - Tool-related styles (tool_use, tool_result, tool-input)
   - Sidechain and thinking styles
   - Session headers and summaries
   - IDE notifications and selections
   - Tool parameter tables

3. Updated edit_diff_styles.css to use variables:
   - File path and marker text colors
   - Context line background (matches code blocks)

Benefits:
- Centralized color management for easier theming
- Clear semantic naming (e.g., "tool-param-sep-color")
- Consistent opacity variants documented in comments
- Foundation for future light/dark theme support

All tests pass (243 passed).

Subject: [PATCH 46/50] Add font family variables and minor CSS refinements
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit introduces CSS font family variables and applies minor
refinements to improve consistency and readability.

Changes:

1. Added font family CSS variables in global_styles.css:
   - --font-monospace: For code and monospace content
   - --font-ui: For UI elements (system-ui based)

2. Applied font family variables throughout:
   - Updated all monospace font declarations to use var(--font-monospace)
   - Updated UI font declarations to use var(--font-ui)
   - Includes: bash styles, code blocks, IDE selections, tool content, etc.

3. Todo content font family:
   - Changed to var(--font-ui) for consistency with assistant output

4. Edit diff line height:
   - Changed from 1.4 to 2ex for better readability

Benefits:
- Centralized font management
- Easy to customize fonts globally
- Consistent typography across all components
- Foundation for future font customization/theming

All tests pass (243 passed).

Subject: [PATCH 47/50] Remove padding from diff character highlighting
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit removes horizontal padding from character-level diff
highlights for a cleaner, more precise visual representation.

Changes:
- Removed `padding: 0 2px;` from .diff-char-removed
- Removed `padding: 0 2px;` from .diff-char-added

The border-radius provides sufficient visual distinction without
the extra padding, resulting in tighter highlighting that better
matches the exact changed characters.

All tests pass (243 passed).

Subject: [PATCH 48/50] Fix sidechain message filtering logic in browser
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Restore proper sidechain filtering behavior that was removed in commit
fdc0e35. Sidechain messages now require BOTH the sidechain filter AND
their message type filter to be active to be shown.

This fixes 5 failing browser tests:
- test_filter_query_param_filters_messages[chromium]
- test_sidechain_message_filtering_integration[chromium]
- test_sidechain_filter_complete_integration[chromium]
- test_timeline_filter_synchronization[chromium]
- test_timeline_synchronizes_with_message_filtering[chromium]

The filtering logic now correctly handles:
1. Sidechain messages: Show if both 'sidechain' filter AND message type
   (user/assistant/tool_use/tool_result) are active
2. Non-sidechain messages: Show if any of their types are active

All 272 non-TUI tests pass (28 browser tests, 244 unit tests).

Subject: [PATCH 49/50] Add markdown rendering for local command output
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Detect and render markdown content in local command output (e.g., from
/context, /help, etc.) as formatted HTML instead of plain preformatted text.

The heuristic checks if the output starts with markdown headers (lines
beginning with #, ##, etc.). When detected, the content is rendered using
mistune instead of being wrapped in 
 tags.

Examples:
- /context command output with tables and headers → rendered as HTML
- Regular command output without markdown → preserved in 
 tags

All 244 unit tests and 28 browser tests pass.

Subject: [PATCH 50/50] Add type annotations to fix pyright errors
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add explicit type annotations to the Edit diff rendering code to resolve
18 pyright type errors. The annotations clarify that:
- diff is a list[str] from difflib.Differ.compare()
- removed_lines and added_lines are list[str]
- old_parts and new_parts are list[str]

Also includes automatic lint fix (removal of unused pytest import from
test_ide_tags.py).

All 244 unit tests pass. Pyright now reports 0 errors.
