For example, if 5 Read tools were called, then their 5 results arrived, the 1st tool_use would be 11 messages away from its result - beyond the limit. New two-pass algorithm: 1. Build dictionaries mapping tool_use_id to message indices 2. Match pairs using O(1) dictionary lookups instead of O(n) scans This handles any distance between tool_use and tool_result, including: - Long-running background tools - Many concurrent fast tools - Async/out-of-order tool results Both _identify_message_pairs() and _reorder_paired_messages() now use dictionary-based approach for O(n) complexity vs O(nΒ²). πŸ€– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- claude_code_log/renderer.py | 133 +++++++++++++++++++----------------- 1 file changed, 69 insertions(+), 64 deletions(-) diff --git a/claude_code_log/renderer.py b/claude_code_log/renderer.py index f91abef4..f7317acb 100644 --- a/claude_code_log/renderer.py +++ b/claude_code_log/renderer.py @@ -1985,7 +1985,24 @@ def _identify_message_pairs(messages: List[TemplateMessage]) -> None: """Identify and mark paired messages (e.g., command + output, tool use + result).

Subject: [PATCH 28/35] Fix: Remove duplicate tool icons and restore sidechain
 icons
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes two issues introduced in the message_title refactoring:

1. Tool use messages were showing duplicate icons - the generic πŸ› οΈ
   from the template plus the specific icon (πŸ“, πŸ“„) from message_title.
   Fixed by removing the generic tool_use icon from the template since
   each tool already has its specific icon in message_title.

2. Sidechain messages lost their icons (πŸ“ for prompt, πŸ”— for assistant).
   Fixed by restoring emoji prefixes to sidechain message titles.

Subject: [PATCH 29/35] Add starts_with_emoji helper for conditional tool icons
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Introduces a helper function to detect if a string starts with an emoji,
allowing the template to conditionally add the generic πŸ› οΈ tool icon only
when the message_title doesn't already have a custom emoji.

Changes:
- Added starts_with_emoji() function checking common emoji Unicode ranges:
  * Emoticons (U+1F600 - U+1F64F)
  * Misc Symbols and Pictographs (U+1F300 - U+1F5FF)
  * Transport and Map Symbols (U+1F680 - U+1F6FF)
  * Supplemental Symbols (U+1F900 - U+1F9FF)
  * Misc Symbols (U+2600 - U+26FF)
  * Dingbats (U+2700 - U+27BF)
- Registered function in Jinja2 environment globals
- Updated template to conditionally add πŸ› οΈ for tool_use only when
  message_title doesn't start with an emoji

This solves both cases:
- Generic tools (Bash, Grep, etc.) get the πŸ› οΈ icon
- Specialized tools (πŸ“ Edit/Write, πŸ“„ Read) keep only their custom icon

Subject: [PATCH 30/35] Fix: Make image preview inline and unify CSS rules
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Changes the Read tool result image preview to use inline span and
consolidates three duplicate CSS rules into a single unified rule.

Changes:
- Use 'preview-text' class for image content summary (more semantic)
- Unified .line-count and .preview-text styling under single rule:
  `.tool-result .line-count, .tool-result .preview-text`
- Removed duplicate rules from .edit-tool-result and .write-tool-content
- Text now appears inline with expander arrow, saving vertical space

Benefits:
- Consistent visual treatment between code and image previews
- Reduced CSS redundancy (3 rules β†’ 1)
- More maintainable stylesheet

Subject: [PATCH 31/35] Fix: Update test expectations for recent changes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Updates test assertions to match recent refactoring changes:

1. test_template_data.py:
   - Changed display_type to message_title in TemplateMessage tests
   - Renamed test method to test_template_message_title_capitalization

2. test_tool_result_image_rendering.py:
   - Removed "(click to expand)" from expected text (simplified to
     "Text and image content" for vertical space savings)

3. test_todowrite_rendering.py:
   - Removed edit-file-path assertion (file path moved to message header)
   - Added comment explaining the architectural change

All tests now pass (244 passed, 58 deselected).

Subject: [PATCH 32/35] Fix: Add type ignore for Jinja2 env.globals type
 checking
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Suppresses pyright error at line 1390 where we add a custom function
to Jinja2's env.globals dictionary.

The error occurs because Jinja2's type stubs are overly restrictive and
only allow specific built-in types (range, dict, Cycler, etc.) rather
than accepting arbitrary callable types. This is a known limitation of
the Jinja2 type stubs.

Our starts_with_emoji function works correctly at runtime; this is
purely a type checking limitation.

Subject: [PATCH 33/35] Fix: Deduplicate version stutters while preserving
 streaming fragments
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

**Problem:**
Claude Code can record duplicate message pairs when upgrading mid-session
(e.g., v2.0.31 β†’ v2.0.34), causing tool results to appear multiple times
in generated HTML reports. These "version stutters" have:
- Same message.id (for assistant) or tool_use_id (for tool results)
- Different Claude Code version numbers
- Different UUIDs but identical content and timestamps

Additionally, normal streaming responses create message fragments with:
- Same message.id and same version
- Different content (text fragment + tool_use fragment)
- These must remain separate (not merged or deduplicated)

**Solution:**
Group messages by unique identifier (message.id or tool_use_id), then:
1. If all same version β†’ Keep ALL (streaming fragments)
2. If different versions β†’ Keep ONLY highest version (deduplicate stutters)

This preserves the correct rendering where streaming fragments appear as
separate consecutive message divs in the HTML output, while removing true
duplicates from version upgrades.

**Implementation:**
- Uses packaging.version.parse for semantic version comparison
- Handles both assistant messages (message.id) and tool results (tool_use_id)
- Preserves messages without unique IDs (e.g., queue-operation)

Tests verify both version deduplication and streaming fragment preservation.

Subject: [PATCH 35/35] Fix: Add type annotations for pyright compliance
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Added type ignore comment and explicit type annotation to resolve pyright
errors in version deduplication logic:
- tool_use_id access now has type ignore comment
- indices_to_keep explicitly typed as set[int]
