This commit introduces HTML formatting for messages, including support for various blocks like headers, text, lists, tables, and expandable sections. It also adds comprehensive unit tests with corresponding HTML fixtures to ensure correct rendering. Co-authored-by: mika <[email protected]>
- Added comprehensive test coverage for all block types (TableBlock, CodeBlock, DividerBlock, ActionsBlock) - Improved fact list styling: removed backgrounds/borders, added max-width:200px on labels - Standardized font-size to 14px across all blocks (fact lists, tables, expandable) - Removed ActionsBlock rendering (not supported in HTML emails, matches adaptive cards) - Made expandable blocks actually expandable using HTML5 details/summary elements - Added visual arrow indicators (▶/▼) to expandable blocks, properly hiding native browser triangles - Enhanced bullet lists with proper semantic HTML (ul/li elements) and automatic pattern detection - All 36 HTML formatter tests passing
CSS property syntax (colons and semicolons in style strings) triggers false positive flake8 E231 and E702 errors. Added noqa comments to suppress these warnings for legitimate CSS syntax within Python string literals.
- Add 800px max-width to main container for better readability - Update container padding to 24px top, 32px left/right, 32px bottom - Match all borders to status color (red/yellow/green) when color is set - Adjust left padding to 28px when colored border is applied (to account for 4px thicker left border) - Set fact list (questions/answers) left column to fixed 160px width - Add 8px extra top and bottom margin to fact list blocks - Add max-height (400px) and scroll to code blocks to prevent excessive vertical space - Fix expandable block arrow to rotate 90° when opened (▶ → ▼) with smooth transition - Update test fixtures to reflect all design changes - Add code_block_long.html fixture to demonstrate scrollable code blocks These changes only affect HTML email formatting and do not impact Slack (Block Kit) or Teams (Adaptive Cards) integrations.
- Corrected string formatting for CSS styles in HTML output - Simplified inline space handling logic in bullet lists - Added flake8 noqa comments to suppress style warnings for CSS syntax These changes enhance the maintainability of the HTML formatter without altering its functionality.
- Update fixtures for all formats (HTML, Adaptive Cards, Block Kit, Markdown, Text) - Reflects enhanced base test suite with additional blocks: - CodeBlock with multi-line code samples - DividerBlock for visual separation - TableBlock with headers and multiple columns - ActionsBlock with dropdown and user select components - Additional inline blocks (MentionBlock, InlineCodeBlock) - All 198 message format tests passing

elementary/messages/formats/html.py (4)
39-49: Tighten class-level constants and clean up unusednoqadirectives
_CONTAINER_STYLESis a mutable class attribute; to satisfy Ruff (RUF012) and make intent clearer, consider either:
- Making it immutable (e.g., a
tuple[str, ...]) and keeping current usagelist(self._CONTAINER_STYLES), or- Annotating it as
ClassVar[Sequence[str]](and importingClassVar) so it’s clearly a shared constant rather than instance state.- The
# noqa: E231,E702onvalue_styleand# noqa: E231on thestyles.append(...)lines are currently unused per Ruff (RUF100). Either remove them or, if you still need to silence formatting checks, reflow those style strings so they don’t trigger the underlying rules in the first place.These are non-functional but will keep lint noise down and make the constants’ intent clearer.
Also applies to: 331-337, 397-411
143-162: Align exception types/messages with intent (unsupported block cases)For unsupported blocks you currently raise
ValueErrorwith a fairly long message in bothformat_message_blockand_format_inline_block. Ruff suggests usingTypeErrorfor invalid types and avoiding long inline messages (TRY003/TRY004). Two possible cleanups:
- Switch to
TypeErrorto reflect “unsupported type” semantics, or- Define a small internal exception (e.g.,
_UnsupportedBlockType) with a concise message and raise that here.Not critical, but doing this (or explicitly deciding to keep
ValueErrorfor consistency withblock_kit) will make the intent and lint posture clearer.Also applies to: 195-211
151-161: Reconsider droppingActionsBlockentirely in HTML outputCurrently
ActionsBlockrenders as"", so any buttons or interactive actions disappear in the HTML/email representation. Even without interactivity, you might want to preserve context, for example:
- Rendering a short text summary like “(3 actions available in the workspace)” or
- Listing action labels as plain text.
This would avoid surprising users who only see the email copy.
109-128: Expandable block rendering and email-client quirksThe
<details>/<summary>approach with a custom arrow and injected<style>is elegant for modern browsers, but in email clients:
<details>/<summary>support is inconsistent, and- Inline
<style>blocks inside the body are often stripped.The current markup degrades reasonably (title + body still present when
detailsisn’t supported), but you may want to:
- Confirm that in key target clients the body content is still visible in some form, and
- Consider avoiding repeated inline
<style>snippets per expandable, or falling back to a simple non-collapsible section for stricter email environments.This is not a blocker but worth validating given the email focus.
Also applies to: 368-390

1-2: HTML fixtures would benefit from formatting for readability and maintainability.While the minified HTML is valid and renders correctly, single-line fixtures make debugging and manual inspection difficult during development. Consider storing these as formatted (indented) HTML for future maintenance, or adding comments explaining the styling logic.

🔇 Additional comments (46)
tests/unit/messages/formats/text/fixtures/all_blocks_green.txt (3)
17-17: Trailing blank line is intentional and consistently applied.Verification confirms the blank line at line 17 appears in all four fixture variants (green, yellow, red, no_color) with identical structure. All files are 18 lines with the same pattern: blank line between the expandable details section and user selection. This is intentional formatter output, not an artifact.
3-5: No issues found. Code block formatting in fixture is correct.The fixture correctly represents the text formatter's output. The
CodeBlockis created with text"def hello_world():\n print('Hello, World!')"and the text formatter (line 107-108 oftext.py) returns it as-is without modification. The 4-space indentation is part of the block's data, not added by the formatter. TheDividerBlockcorrectly formats to"--------------------------------". The fixture is properly tested bytest_format_message_body_all_blocksand is consistent with the formatter implementation.
10-13: ASCII table format is correctly generated and consistent.The TextFormatter delegates table formatting to the
tabulatelibrary withtablefmt="simple"(line 93 ofelementary/messages/formats/text.py), which deterministically generates ASCII tables with column widths based on maximum content length. Fixtures confirm consistent formatting across all color variants (green, red, yellow, no_color), with the 11-character column width being the deterministic result of tabulate's width calculation for your test data.tests/unit/messages/formats/html/fixtures/bullet_list.html (1)
1-1: HTML fixture markup is well-formed and email-ready.The inline styling is comprehensive and appropriate for email clients (no external stylesheets). Emoji handling with margin spacing looks correct, and the list structure properly distinguishes between plain bullets and checkmark-prefixed items.
tests/unit/messages/formats/adaptive_cards/fixtures/all_blocks_green.json (1)
26-41: JSON structure is valid and additions are well-integrated.The emphasis container (lines 26–41) with monospace code rendering and the table block (lines 44–196) follow proper AdaptiveCard schema. The table with 3 columns and 2 data rows is correctly structured with TableRow and TableCell elements wrapping TextBlocks. Positioning within the card body is logical.
Also applies to: 44-196
tests/unit/messages/formats/text/fixtures/all_blocks_yellow.txt (1)
1-18: Plain text fixture layout is clear and consistent.The structure properly represents code blocks, tables, and details sections using plain text formatting. Layout aligns with comparable sections in other format fixtures (HTML, Markdown). Blank lines provide appropriate visual separation.
tests/unit/messages/formats/html/fixtures/text_length_50.html (1)
1-1: HTML email fixture is properly formatted with consistent styling.The outer container uses appropriate inline styles for email rendering (font stack, colors, borders, padding). The truncated Lorem ipsum text aligns with the fixture name intent (text_length_50), suggesting this tests text truncation or length handling.
tests/unit/messages/formats/adaptive_cards/fixtures/all_blocks_yellow.json (1)
26-41: AdaptiveCard fixture additions look structurally sound and consistentThe new emphasis Container with monospace code and the 3-column Table are valid AdaptiveCard structures and align with the pattern used in other color variants; no issues from a fixture perspective.
Also applies to: 76-195
tests/unit/messages/formats/adaptive_cards/fixtures/all_blocks_no_color.json (1)
26-41: No-color AdaptiveCard fixture changes are consistent with other variantsThe added emphasis Container with code and the 3-column Table follow the same schema and ordering as the colored fixtures, keeping cross-format tests aligned.
Also applies to: 76-195
tests/unit/messages/formats/adaptive_cards/fixtures/all_blocks_red.json (1)
26-41: Red AdaptiveCard fixture updates maintain cross-variant parityThe emphasis Container and Table are correctly inserted and mirror the other fixtures’ structure, which is important for verifying formatter behavior uniformly across colors.
Also applies to: 76-195
tests/unit/messages/formats/html/fixtures/table_block_8_1.html (1)
1-1: HTML table fixture matches formatter output shapeThe container and table styles align with the constants in
HTMLFormatter, and the header/body structure is correct for the table-block tests.tests/unit/messages/formats/html/fixtures/fact_list.html (1)
1-1: Snapshot fixture—verify implementation context.This HTML fixture depends on the HTMLFormatter implementation generating it. Without access to the implementation code and its test harness, I cannot independently verify whether the styling, structure, and output are correct. Please ensure the HTMLFormatter produces this output consistently and that tests properly validate against it.

1-1: Snapshot fixture—verify implementation context.Verify that the HTMLFormatter renders 5-column tables with longer cell content, maintains visual balance, and applies consistent truncation/overflow handling as expected.
tests/unit/messages/formats/html/fixtures/code_block_500.html (1)
1-1: Snapshot fixture—verify implementation context.Verify that the HTMLFormatter applies scrollable overflow styling to code blocks containing longer content, with the max-height constraint properly enforced.
tests/unit/messages/formats/html/fixtures/table_block_30_5.html (1)
1-1: Snapshot fixture—verify implementation context.Verify that the HTMLFormatter correctly renders 5-column tables with shorter cell content, maintaining the same styling consistency as longer-content variants.
tests/unit/messages/formats/html/fixtures/table_block_8_2.html (1)
1-1: LGTM: Email-compatible HTML fixture.This fixture properly uses inline styles throughout (required for email clients) and provides a clean 2-column table structure. The minified format is appropriate for test fixtures.
tests/unit/messages/formats/html/fixtures/colored_header.html (1)
1-1: LGTM: Colored container fixture with proper email styling.The fixture demonstrates color-accented container styling with a left border emphasis, using inline CSS appropriate for email clients.
tests/unit/messages/formats/html/fixtures/table_block_8_5.html (1)
1-1: LGTM: Multi-column table fixture.This fixture validates 5-column table rendering with consistent inline styling, ensuring broader table layout coverage in the test suite.
tests/unit/messages/formats/html/test_html.py (1)
1-19: LGTM: Clean test implementation.The test class properly implements the
BaseTestFormat[str]interface with minimal, focused methods. The implementation correctly:
- Wraps
format_html()for the test framework- Resolves fixture paths with the
.htmlextension- Delegates assertion logic to the shared utility
Test coverage is inherited from the comprehensive parametric tests in
BaseTestFormat, which exercise multiple block types, color variants, and table configurations as shown in the relevant code snippets.tests/unit/messages/formats/html/fixtures/table_block_200_3.html (1)
1-1: LGTM: Long-text table fixture.This fixture validates table rendering with longer cell content (200 characters), ensuring the formatter handles text overflow and wrapping correctly across 3 columns.
tests/unit/messages/formats/html/fixtures/table_block_200_4.html (1)
1-1: LGTM: 4-column long-text table fixture.This fixture complements the systematic test coverage for table rendering across different column counts (1-5) with longer cell content.
tests/unit/messages/formats/html/fixtures/table_block_30_2.html (1)
1-1: LGTM: Medium-text table fixture.This fixture covers the medium-length text scenario (30 characters) for 2-column tables, filling a gap in the test matrix between short (8 char) and long (200 char) content.
tests/unit/messages/formats/html/fixtures/table_block_200_2.html (1)
1-1: LGTM: Completes long-text fixture coverage.This fixture provides the 2-column variant with 200-character content, completing the systematic test coverage across the (text_length × column_count) matrix for table rendering validation.
tests/unit/messages/formats/html/fixtures/expandable_block.html (1)
1-1: Expandable block fixture is well-formed and follows HTML5 standards.The fixture correctly uses the
detailselement with appropriate inline styling, CSS animation for the chevron, and proper nesting. Good implementation of the collapsible pattern for email-safe HTML.tests/unit/messages/formats/html/fixtures/all_blocks_no_color.html (1)
1-2: No-color variant fixture is consistent and appropriately styled.The fixture correctly omits the left accent border present in colored variants and uses neutral gray styling (#e5e7eb) for borders and (#1f2937) for text. The styling accurately represents a no-color message variant.
tests/unit/messages/formats/html/fixtures/all_blocks_red.html (1)
1-2: Red color variant fixture is properly styled and consistent.The red styling is correctly applied to borders (#ff0000) with an appropriate left accent border. The fixture aligns with the yellow variant's approach to color customization and appears email-safe and well-rendered.
tests/unit/messages/formats/block_kit/fixtures/all_blocks_yellow.json (1)
2-27: Block Kit yellow fixture structure is consistent with green variant.The fixture correctly maintains identical block structure to the green variant with only the color value differing (#ffcc00 vs #33b989). Action block, static_select options, and users_select are properly defined and formatted. This consistency across color variants supports reliable testing of color rendering.
Also applies to: 58-120, 129-129
tests/unit/messages/formats/block_kit/fixtures/all_blocks_red.json (1)
2-27: Block Kit red fixture maintains consistency with green and yellow variants.The red color (#ff0000) is correctly applied, and all block structures remain identical across the color variants. This consistent fixture structure across all_blocks_green.json, all_blocks_yellow.json, and all_blocks_red.json demonstrates good test design for color-variant coverage.
Also applies to: 58-120, 129-129
tests/unit/messages/formats/block_kit/fixtures/all_blocks_green.json (1)
72-120: No issues found. Option value casing is consistent and intentional across all fixtures and implementations.The verification confirms the priority dropdown uses a consistent pattern across all four color variants (green, yellow, red, no_color):
- Display text: "High", "Medium", "Low" (title case)
- Values: "high", "medium", "low" (lowercase)
This convention is reflected in the test expectations (
base_test_format.pylines 301-312) and passed through implementations without modification. No transformation or validation of the casing occurs downstream.tests/unit/messages/formats/block_kit/fixtures/all_blocks_no_color.json (1)
28-130: The review comment is incorrect: the no-color fixture properly reflects the intended code behavior.The source code in
elementary/messages/formats/block_kit.pyexplicitly omits the"color"property when no color is specified. Thebuild()method only adds the color property ifcolor_codeis truthy (line 386-387:if color_code:). Whenmessage.colorisNone,color_codeevaluates toNone, and no color property is added to the attachment. This is by design—as documented in the_get_final_blocks()method comment: "If we don't have a color, everything is a regular message." The fixture is correct, and there is no intention to use a neutral/default color like gray.Likely an incorrect or invalid review comment.
tests/unit/messages/formats/base_test_format.py (4)
9-9: LGTM: Action block imports added.The new imports for
ActionsBlock,DropdownActionBlock,DropdownOptionBlock, andUserSelectActionBlockare correctly added to support the expanded test coverage.Also applies to: 12-13, 28-28

TableBlockwith headers and rows is properly formatted with matching column counts. This addition enhances the test coverage for tabular data rendering.
298-314: The review comment is incorrect. HTMLFormatter already handles ActionsBlock appropriately for email context.The original concern about interactive elements in HTML emails is unfounded. The code at
elementary/messages/formats/html.py:158-160explicitly handlesActionsBlockby returning an empty string, with a comment stating: "Not supported in HTML emails (no interactivity without JavaScript)". This is the correct design for email-safe HTML rendering. The test is valid and requires no changes.Likely an incorrect or invalid review comment.

<details>/<summary>elements with inline<style>tags to handle expand/collapse arrow rotation via CSS.

🧩 Analysis chain
Verify email client support for <details> and <summary> elements.
The fixture includes <details> and <summary> elements for expandable content. These HTML5 elements have very limited support in email clients—most major clients (Gmail, Outlook, Yahoo Mail, etc.) do not render them correctly or strip them entirely. Additionally, the inline <style> tag for the details marker may be removed by email clients that sanitize CSS.
Consider generating a verification script or consulting documentation to confirm whether the HTMLFormatter is intended for use in email clients or for web-based HTML rendering. If this is for email, a fallback approach (e.g., always-expanded content or a link to view details) might be necessary.
🌐 Web query:
Do email clients like Gmail and Outlook support HTML5 details and summary elements?
💡 Result:
Short answer: generally no — major webmail and Outlook clients do not reliably support the HTML5
disclosure widget in email. Apple Mail (native Mail on macOS/iOS) and other WebKit-based clients may render them, but Gmail (web and apps), Outlook desktop (Word rendering engine) and most webmail/Windows Outlook variants either strip, ignore, or do not correctly render those elements — so you should not rely on them in production email. [1][2][3][4]
Sources:
- Mailchimp — limitations of HTML email (avoid modern/interactive HTML features). [1]
- WooCommerce / developer guidance — “avoid HTML5 elements in email; many clients use old rendering engines.” [2]
- Email on Acid / Gmail specifics — Gmail’s special rendering and common CSS/HTML limitations in email. [3]
- Campaign Monitor — email client CSS/feature support testing and guidance (shows diversity/limits of client support). [4]
If you want, I can run a focused compatibility matrix (Litmus/Campaign Monitor results) for specific Gmail/Outlook versions you care about.
I need to verify whether this HTMLFormatter is intended for email rendering or web-based HTML output, as this context is critical to assess the validity of the review comment.

Verification confirms major email clients (Gmail, Outlook, Yahoo Mail) do not support HTML5 <details> and <summary> elements. The HTMLFormatter (elementary/messages/formats/html.py) is explicitly designed for email use, as evidenced by line 159's comment excluding ActionsBlock from email rendering. However, the _format_expandable_block() method (lines 368–390) generates <details> elements with inline CSS styling, creating a compatibility issue.
The formatter should implement a fallback for email rendering—such as always-expanded content or a link to view details—rather than using unsupported HTML5 elements. Update the formatter implementation to ensure email-compatible output; the fixture will then automatically reflect the corrected behavior.
🤖 Prompt for AI Agents
In elementary/messages/formats/html.py around lines 368 to 390,
_format_expandable_block() currently emits HTML5 <details>/<summary> which major
email clients ignore; replace this with an email-compatible fallback (e.g.,
render the summary as a bolded heading or clickable "View details" link and
always include the details content expanded beneath it or provide a link to a
hosted view), remove the <details>/<summary> tags and associated CSS, and ensure
the output uses inline styles only and matches the fixtures expected by tests
(update the tests/fixtures if necessary to reflect the always-expanded or
link-based fallback).
