| ❯ let's add HTML entity support to mdriver. One I've seen in some markdown | |
| files is ` `, but let's add support for some sensible subset of HTML | |
| entities that can reasonably be displayed on the terminal. Before adding | |
| them, please present me with a table of the ones you've chosen to | |
| support, and what their replacements will be | |
| ⏺ I'll propose a sensible subset of HTML entities for terminal display. Here's my recommended set: | |

| Total: 32 named entities | |
| Additional Support | |
| I'd also recommend supporting: | |
| - Numeric decimal references:   → character at codepoint 160 | |
| - Numeric hex references:   → character at codepoint 0x00A0 | |
| This allows any Unicode character to be specified, covering edge cases without bloating the named entity list. | |
| Notes | |
| 1. All these characters render correctly in modern terminal emulators with UTF-8 | |
| 2. The 5 XML entities (amp, lt, gt, quot, apos) are required for proper HTML/XML compatibility | |
| 3. Typographic entities are commonly used in documentation | |
| 4. I've excluded entities that don't display well in monospace fonts (like Greek letters, which need context) | |
| Does this set look good, or would you like me to add/remove any entities? | |
| ❯ looks good, make the changes necessary | |

| ⏺ All tests pass. Let me update the todo list. | |
| ⏺ Done! Here's a summary of the changes: | |
| Changes Made | |
| src/lib.rs: | |
| 1. Added a static HTML_ENTITIES HashMap with 32 named entities (lines 12-56) | |
| 2. Added decode_html_entity() function (lines 1958-2027) that: | |
| - Decodes named entities (& → &) | |
| - Decodes decimal numeric entities (© → ©) | |
| - Decodes hex numeric entities (© → ©) | |
| - Supports entities with or without trailing semicolons | |
| 3. Integrated entity decoding into format_inline() (lines 1547-1554) | |
| tests/unit.rs: | |
| Added 28 new tests in the html_entities module covering: | |
| - All 5 XML entities (amp, lt, gt, quot, apos) | |
| - Whitespace (nbsp) | |
| - Typographic entities (ndash, mdash, hellip, curly quotes, bull) | |
| - Symbols (copy, reg, trade, deg, math operators) | |
| - Fractions (frac14, frac12, frac34) | |
| - Currency (cent, pound, euro, yen) | |
| - Arrows (larr, rarr, uarr, darr) | |
| - Numeric entities (decimal and hex) | |
| - Edge cases (entities without semicolons, unknown entities, ampersands alone) | |
| All 66 unit tests and 5 conformance tests pass. | |

| 188 **Note**: Image rendering requires a terminal that supports | |
| the kitty graphics protocol. In terminals without support, | |
| images will display as alt text. | |
| 189 | |
| 190 + ## HTML Entity Support | |
| 191 + | |
| 192 + mdriver decodes HTML entities in markdown text, supporting | |
| +both named entities and numeric character references. | |
| 193 + | |
| 194 + ### Supported Named Entities | |
| 195 + | |
| 196 + | Entity | Character | Description | | |
| 197 + |--------|-----------|-------------| | |
| 198 + | **Essential (XML)** | | |
| 199 + | `&` | `&` | Ampersand | | |
| 200 + | `<` | `<` | Less than | | |
| 201 + | `>` | `>` | Greater than | | |
| 202 + | `"` | `"` | Quotation mark | | |
| 203 + | `'` | `'` | Apostrophe | | |
| 204 + | **Whitespace** | | |
| 205 + | ` ` | | Non-breaking space | | |
| 206 + | **Typographic** | | |
| 207 + | `–` | `–` | En dash | | |
| 208 + | `—` | `—` | Em dash | | |
| 209 + | `…` | `…` | Horizontal ellipsis | | |
| 210 + | `‘` | `'` | Left single quote | | |
| 211 + | `’` | `'` | Right single quote | | |
| 212 + | `“` | `"` | Left double quote | | |
| 213 + | `”` | `"` | Right double quote | | |
| 214 + | `•` | `•` | Bullet | | |
| 215 + | `·` | `·` | Middle dot | | |
| 216 + | **Symbols** | | |
| 217 + | `©` | `©` | Copyright | | |
| 218 + | `®` | `®` | Registered | | |
| 219 + | `™` | `™` | Trademark | | |
| 220 + | `°` | `°` | Degree | | |
| 221 + | `±` | `±` | Plus-minus | | |
| 222 + | `×` | `×` | Multiplication | | |
| 223 + | `÷` | `÷` | Division | | |
| 224 + | **Fractions** | | |
| 225 + | `¼` | `¼` | One quarter | | |
| 226 + | `½` | `½` | One half | | |
| 227 + | `¾` | `¾` | Three quarters | | |
| 228 + | **Currency** | | |
| 229 + | `¢` | `¢` | Cent | | |
| 230 + | `£` | `£` | Pound | | |
| 231 + | `€` | `€` | Euro | | |
| 232 + | `¥` | `¥` | Yen | | |
| 233 + | **Arrows** | | |
| 234 + | `←` | `←` | Left arrow | | |
| 235 + | `→` | `→` | Right arrow | | |
| 236 + | `↑` | `↑` | Up arrow | | |
| 237 + | `↓` | `↓` | Down arrow | | |
| 238 + | |
| 239 + ### Numeric Character References | |
| 240 + | |
| 241 + In addition to named entities, mdriver supports numeric | |
| +references for any Unicode character: | |
| 242 + | |
| 243 + - **Decimal**: `©` → `©` | |
| 244 + - **Hexadecimal**: `©` → `©` | |
| 245 + | |
| 246 + ### Example | |
| 247 + | |
| 248 + ```bash | |
| 249 + $ echo "5 < 10 — Tom & Jerry © 2024" | | |
| +mdriver | |
| 250 + 5 < 10 — Tom & Jerry © 2024 | |
| 251 + ``` | |
| 252 + | |
| 253 ## Conformance Test Suite | |
| 254 | |
| 255 This project uses a comprehensive conformance test suite to | |
| verify streaming behavior, markdown parsing, and ANSI | |
| formatting. | |
| ⏺ Bash(cargo test 2>&1 | tail -20) | |
| ⎿ test strip_ansi_tests::test_strip_basic_sgr ... ok | |
| test strip_ansi_tests::test_strip_osc8_hyperlink ... ok | |
| test strip_ansi_tests::test_strip_osc8_with_styling ... ok | |
| … +18 lines (ctrl+o to expand) | |
| ⏺ Done. I added a new "HTML Entity Support" section to the README after the "Image Rendering" section. It includes: | |
| - A table of all 32 supported named entities organized by category | |
| - Documentation of numeric character references (decimal and hex) | |
| - An example showing entity decoding in action | |

| - tests/unit.rs - Added 28 tests for entity decoding | |
| - README.md - Added HTML Entity Support documentation section | |
| ⏺ The /export command is handled by Claude Code directly - it will save the conversation transcript to a file. I don't have a tool to execute this, but your CLI should process it and show you the export location. | |
