🚀 Element X+ (v26.09.09)

🇬🇧 English: Release Notes (v26.09.09)

Element X+ v26.09.09 is a major feature and refinement update. It introduces an architectural two-level AST message parser, full TextMate grammar syntax highlighting, interactive code cards with full-screen viewers, deep UI/UX gesture improvements across messages, comprehensive bilingual localization, and adaptive compact Markdown/HTML table column width layout.

🌟 What's New

1. 🏗️ Two-Level AST Message Pipeline (MessageBlock & InlineNode)

  • Robust Layout Engine: Completely re-engineered rich message rendering from legacy regex-based parsing to an AST-driven pipeline (HtmlToMessageAstParser & MarkdownToMessageAstParser).
  • Clean Block/Inline Separation: Block elements (Paragraph, Heading, CodeBlock, LatexBlock, Table, Quote, List, Rule) and inline elements (Text, Inline Math, Code, Links, Bold, Italic) render hierarchically without layout breakage or recursion crashes.

2. 🎨 TextMate Syntax Highlighter Engine (VS Code / TM4E Parity)

  • True Headless Tokenizer: Integrated the industry-standard Eclipse TM4E engine via Sora Editor, parsing code lines with multi-line grammar state tracking (ruleStack).
  • Comprehensive Language Support: Highlighting for Kotlin, Java, Python, Rust, JavaScript, TypeScript, JSON, Shell/Bash, HTML/XML, and C/C++.
  • Intelligent Detection: Auto-infers languages using Shebang markers (#!/bin/bash, #!/usr/bin/env python), command patterns (sudo, curl, git), and structured data formats when language tags are absent.

3. 💻 Interactive Code Blocks & Fullscreen Viewer

  • Collapsible Code Cards: Long code snippets in timeline bubbles automatically truncate to 8 lines with a clean "Expand all" action bar.
  • Strict Line Number & Copy Isolation: Left gutter displays line numbers enclosed in DisableSelection. Copying via button or long-press selection never includes line numbers.
  • Fullscreen Viewer (CodeFullscreenViewer):
    • Pinch-to-Zoom: Two-finger zoom smoothly rescales font size from 75% to 250% with strict line-height parity between line numbers and code text.
    • Full-Screen Free Horizontal Scrolling: Resolved touch interception so horizontal panning works across the entire screen (including bottom blank areas) with natural swipe direction (swipe left reveals right content).
    • Zero-Bounce Fling: Fixed double-scrollable fling competition, ensuring natural deceleration without spring-back bounce.

4. 🔍 Fullscreen Viewers for Formulas & Tables

  • Fullscreen LaTeX Viewer (LatexFullscreenViewer): Tap block formulas to launch an edge-to-edge dialog with two-dimensional panning and two-finger pinch-to-zoom.
  • Fullscreen Table Viewer (TableFullscreenViewer): Complex, wide Markdown and HTML tables can be inspected in full-screen with smooth multi-touch navigation.

5. 💬 Smooth Interaction & Context Menu Fixes

  • Universal Bubble Long-Press: Tuned gesture hit testing across messages so long-pressing anywhere (text, code borders, formula cards, or blank space) reliably summons the message action sheet.
  • Rich Message Quotes & Lists: Beautiful native rendering for nested block quotes and bulleted/numbered lists.

6. 📐 LaTeX Formula Rendering Compatibility

  • Support for @ Symbol: Solved crash caused by missing ASCII 64 (@) in JLatexMath fonts by automatically mapping it to \mathrm{at}\ (e.g. @alice:example.org).
  • Line Break Spacing Parameters: Automatically strips optional bracket arguments on line breaks like \\[4pt], \\[-2pt], and \\[14pt].
  • Monospace Font Macro Parity: Automatically normalizes \texttt macros to JLatexMath's native \mathtt.

7. 🌐 Comprehensive Bilingual Localization & Architecture Cleanup

  • Full UI Localization (i18n): All interactive controls across code blocks, tables, LaTeX math cards, and full-screen viewers (e.g. "Copy code", "Copy Markdown", "Copy LaTeX", "Select text", "Fullscreen") now seamlessly adapt to the device system language (English / Chinese) without hardcoded strings.
  • Dead Code Cleanup: Eliminated legacy Phase 1 prototype code and obsolete regex spans, keeping the codebase clean, maintainable, and lean.

8. 📊 Adaptive Table Column Layout & Visual Math Sizing

  • Accurate Visual Width Estimation: Replaced naive raw string character counting with TableVisualWidth. LaTeX formulas now accurately estimate rendered symbol size (e.g. \hat{\theta} is measured as 1 visual symbol instead of 12 raw characters).
  • Proportional Space Allocation: Differentiates half-width ASCII (0.55) and full-width CJK (1.0) characters, lowering minimum column width to 48dp so narrow symbol/index columns no longer swallow the whole mobile screen width.

🇨🇳 中文：更新说明 (v26.09.09)

Element X+ v26.09.09 是重大功能与排版体验优化版本。本次升级带来了统一的双层 AST 消息解析架构、工业级 TextMate 语法高亮引擎、支持行号隔离与自由缩放的全屏代码查看器、全方位的消息交互手势优化、完整的中英双语系统自适应国际化支持，以及全新的自适应表格列宽计算系统。

🌟 更新内容

1. 🏗️ 全新双层 AST 消息解析与原生渲染架构

  • 彻底告别正则拼接：构建了基于 AST 的两层消息处理管线（HtmlToMessageAstParser 与 MarkdownToMessageAstParser），消除了复杂消息混排时的排版混乱与崩溃隐患。
  • 块级与行内分层解耦：块级节点（段落、标题、代码块、数学公式、表格、引用块、列表、分割线）与行内节点（纯文本、行内公式、行内代码、超链接、加粗、斜体等）统一组织，层次清晰。

2. 🎨 TextMate 语法高亮引擎（对齐 VS Code 代码着色）

  • 无 UI 侵入的 Headless 分词引擎：基于 Eclipse TM4E / Sora Editor 核心，逐行分析语法并保存词法栈状态（ruleStack），精准映射到 Compose AnnotatedString 的 SpanStyle。
  • 广泛的语言支持：原生支持 Kotlin、Java、Python、Rust、JavaScript、TypeScript、JSON、Shell/Bash、HTML/XML、C/C++ 等主流语言。
  • 智能语言自动推断：自动识别 Shebang（#!/bin/bash 等）、常见命令行操作（sudo、curl、git 等）以及 JSON 结构，无语言标注也能拥有高亮。

3. 💻 交互式代码卡片与全屏沉浸式代码查看器

  • 智能折叠：时间线气泡中超过 8 行的长代码自动截断，提供优雅的“展开全部”操作栏。
  • 行号与选区严格隔离：左侧行号栏由 DisableSelection 严格包裹，无论是点击“复制”按钮还是长按光标手柄框选复制，复制内容绝对不含行号。
  • 全屏代码查看器 (CodeFullscreenViewer) 深度优化：
    • 自由缩放：支持双指捏合缩放（75%~250%），行号与代码行高始终保持 1:1 精确对齐。
    • 全域横向平滑滚动：解决代码只有几行时屏幕下方无法左右滑动的问题。屏幕底部全域均可自然横向滚动，手势方向符合自然直觉（手向左滑展现右侧内容）。
    • 惯性滑动永不回弹：彻底消除多层嵌套滚动带来的 Fling 冲突，快速滑动松手后平滑自然减速停止，绝不反弹。

4. 🔍 公式与表格沉浸式全屏查看器

  • 全屏公式查看器 (LatexFullscreenViewer)：轻触公式卡片即可进入全屏漫游模式，支持双指自由缩放与二维拖拽，复杂公式、长矩阵一览无余。
  • 全屏表格查看器 (TableFullscreenViewer)：大型宽表格支持全屏多点触控与漫游查看。

5. 💬 消息手势与富文本细节调优

  • 全域长按菜单修复：优化手势分发与命中测试，长按普通文本、代码卡片、公式或气泡空白处的任何位置均能稳定弹出操作气泡与菜单。
  • 引用块与列表增强：原生渲染多层 Markdown 块引用（Quote）与有序/无序列表，对齐现代排版体验。

6. 📐 LaTeX 复杂数学公式兼容性深度增强

  • 支持 @ 符号自动转义：修复因 JLatexMath 字体库缺少 ASCII 64 (@) 导致的渲染崩溃，自动规范映射为 \mathrm{at}\ （如优雅支持 @alice:example.org 等 Matrix ID）。
  • 换行间距参数兼容：自动兼容并剥离 \\[4pt]、\\[-2pt]、\\[14pt] 等可选间距参数，避免非法符号错误。
  • 等宽字体宏兼容：自动将 \texttt 宏映射至 JLatexMath 原生支持的 \mathtt。

7. 🌐 全系统多语言自适应 (i18n) 与架构精简

  • 全交互组件国际化：交互代码卡片、表格、LaTeX 查看器及三大全屏查看器中的所有操作文案（“复制代码”、“复制 Markdown”、“复制 LaTeX”、“选择文本”、“全屏”等）全面接入 Element X 官方国际化架构（temporary.xml），自适应中英文环境，消除硬编码。
  • 冗余原型代码清理：彻底移除第一阶段过渡原型渲染代码与废弃工具类，保持代码库整洁轻量。

8. 📊 自适应表格列宽与数学符号视觉测量

  • 精确视觉等效折算：使用 TableVisualWidth 替代生硬的源码字符数统计，去除 LaTeX 控制宏并识别实际公式符号（如 \hat{\theta} 真实折算为 ~1 个符号宽，彻底解决由于源码长度导致单列过宽、强占全屏的问题）。
  • 紧凑列宽分配：严格区分半角与全角字符，将紧凑列最小宽度下调至 48dp，常用两列/三列表格可在手机屏幕上一屏容纳全部内容，免除不必要的横向滑动。

🚀 Element X+ (LaTeX Formula Rendering Edition)

🇬🇧 English

Element X+ is an enhanced version of Element X Android featuring a native, high-performance LaTeX math rendering engine, tailored for academic communication, technical discussions, and scientific collaboration.

✨ Key Features

  1. 📐 Native LaTeX Math Rendering

    • Inline Math: Seamlessly renders $E=mc^2$, $\nabla \cdot \mathbf{B} = 0$ within message bubbles while maintaining natural typographic baseline alignment.
    • Block Math: Displays $$ ... $$ formulas in standalone, horizontally-scrollable cards. Complex equations, fractions, and large matrices remain crisp without down-scaling, line wrapping, or clipping.
    • Matrix MSC2191 Compliant: Fully compatible with the Matrix MSC2191 math standard used by Element Web and Element Desktop.

  2. 🧠 Broad Environment Compatibility

    • Built-in automatic normalization for popular LaTeX environments including align* / align, gather* / gather, equation* / equation, matrix / pmatrix, and aligned.
    • Tolerates extra whitespace and formatting variations gracefully.

  3. 📋 Smooth Interaction & Fast Copy

    • Single-tap formula card: Copies the raw LaTeX code directly to the clipboard with an instant toast notification.
    • Long-press message: Opens the standard context menu with a "Select text" sheet for precise text selection and copying.

  4. ⚙️ Toggle in Advanced Settings

    • Easily enable or disable formula rendering anytime under Settings → Advanced Settings → Render mathematical formulas.
    • When disabled, messages fallback to raw LaTeX source text without custom rendering.

  5. 📱 Side-by-Side Coexistence

    • Packaged as io.element.android.x.custom and labeled as Element X+.
    • Can be installed and run alongside the official Element X release without signature conflicts or overwrites.

📦 Installation Guide

  • Most users (64-bit ARM devices): Download app-fdroid-arm64-v8a-release.apk.
  • Older 32-bit devices: Download app-fdroid-armeabi-v7a-release.apk.
