Beamer Academic
Generate publication-quality Beamer slides from an academic paper in one automated pipeline.
Pipeline Overview
论文 → 素材提取 → 大纲生成 → [用户确认] → 内容填充 → 编译 → [交互修改循环]
Phase 0: Environment Check & Input Clarification
0.1 Locate Thesis File
Search current directory for thesis in priority order:
.tex (LaTeX source — best quality, figures/equations directly reusable).docx (Word — good for text extraction, figures embedded).pdf (PDF — acceptable but figure extraction may lose quality)
If multiple candidates found, ask user which one.
If none found, prompt: "请把论文文件放到当前目录（支持 .tex / .docx / .pdf）"
Recommend .tex or .docx over PDF: PDF figure extraction can produce low-quality raster images.
If user only has PDF, warn:
注意：PDF 提取的图片可能有质量损失。如果你有论文的 Word 或 LaTeX 源文件，建议优先使用。
0.2 Check LaTeX Environment
which xelatex
If missing, recommend user to install (this is a one-time setup, not optional):
你的系统还没有安装 LaTeX 环境。beamer PPT 需要 xelatex 编译，我来帮你装一下：
Then provide the command for user's OS and offer to run it:
| OS | Command |
|---|
| macOS | brew install --cask mactex-no-gui (推荐，约3.5GB，装一次永久可用) |
| Ubuntu/Debian | sudo apt install texlive-xetex texlive-lang-chinese texlive-fonts-recommended |
| Fedora/RHEL | sudo dnf install texlive-xetex texlive-xecjk |
| Windows (WSL) | sudo apt install texlive-xetex texlive-lang-chinese |
| Arch | sudo pacman -S texlive-xetex texlive-langchinese |
Wait for installation to complete, verify with which xelatex, then proceed.
If user explicitly refuses to install (rare), fallback: deliver .tex + .sty + figures, suggest Overleaf.
0.3 Beamer Template (Ask User First)
Ask user about existing school beamer template:
你的学校/课题组有现成的 beamer 模板吗？（比如导师或师兄给过的 .sty 文件）
- 有：请放到当前目录，我直接使用
- 没有：我来帮你找或用内置通用模板
If user has a template: use it directly, skip the built-in theme.
If user has NO template:
- Ask for school name
- Search for existing public beamer templates for that school:
- GitHub search:
{school name} beamer template
- Common sources: Overleaf Gallery, CTAN
- If found: download and use (notify user which template)
- If not found: use built-in
assets/beamerthemeAcademic.sty with school logo
- Ask: "你能提供学校 logo 图片吗？（放到当前目录即可）"
- If no logo available: search online for the school's logo, or proceed without logo
0.4 Configuration
Check for config.yaml in current directory:
- Exists: read and use.
- Missing: ask user for basic info, then generate from template at
assets/config.yaml.
Required user info (ask if not in config):
- Institution name and department
- Author name, supervisor, major
- Report type:
defense | proposal | conference
- Color preference:
blue | red | green | purple | teal
- Time limit (minutes): affects page count and content density
- Language: thesis language vs. PPT language (e.g., 英文论文 → 中文PPT)
- Chapnote preference: "每页要不要显示'对应论文 §X.X'的标注？"（some users find it helpful for committee, others find it cluttered）
0.5 Language Strategy
If thesis language ≠ PPT language, establish rules upfront:
你的论文是英文，PPT 要做中文版吗？
对于专业术语，我会：
- 首次出现用"中文（English）"格式
- 之后统一用中文
- 公式/变量名保持英文不翻译
这样处理可以吗？
Build a terminology mapping table (stored in materials/terms.md):
| English | 中文 | 首次出现页 |
|---------|------|-----------|
| disparity | 形态多样性 | P4 |
| diversity | 分类丰富度 | P4 |
| Ornstein-Uhlenbeck | OU 过程 | P8 |
Ensure 术语一致性: same concept uses same translation across all pages.
Phase 1: Material Extraction
Create materials/ directory. Extraction strategy depends on input format:
From .tex source (best)
- Figures: locate
\includegraphics paths, copy originals → materials/figures/
- Tables: extract
tabular/table environments → materials/tables/
- Equations: extract
equation/align/$$ blocks → materials/equations.md
- Structure: parse
\chapter/\section hierarchy → materials/structure.md
From .docx
- Figures: extract embedded images (python-docx or unzip) →
materials/figures/
- Tables: extract table contents →
materials/tables/
- Equations: extract OMML/LaTeX equations →
materials/equations.md
- Structure: parse heading hierarchy →
materials/structure.md
From .pdf (fallback)
- Figures: use
pdfimages or read PDF for embedded images → materials/figures/
- ⚠️ Quality may degrade. Prefer vector (PDF/SVG) extraction when possible.
- Tables: read and reconstruct →
materials/tables/
- Equations: read and convert to LaTeX →
materials/equations.md
- Structure: parse chapter/section from text →
materials/structure.md
1.2 Material Confirmation (In-Conversation)
After extraction, present a figure catalog to user in conversation:
🖼️ 素材库（共提取 12 张图）
| # | 文件名 | 来源 | 内容描述 |
|---|
| 1 | fig_001.png | 论文图1 | 地质年代柱状图 |
| 2 | fig_002.png | 论文图4 | PCoA 碎石图 |
| 3 | fig_003.png | 论文图8 | 形态空间散点图 |
| ... | | | |
哪些图是你答辩必须展示的？ 可以说：
- "1, 3, 5, 8 必须用"
- "图7 不用了，跟图5 重复"
- "全部都可能用到"
This ensures:
- Key figures won't be missed in layout assignment
- User has a mental model of available materials before the outline phase
- Low-quality or duplicate figures can be flagged early
Phase 2: Brainstorm Outline (Interactive, In-Conversation)
This phase determines the entire presentation structure through conversation with the user. All confirmation happens IN THE CHAT — never ask user to open a file.
2.0 Chapter Structure Principle
Follow the thesis's own structure as the PRIMARY basis for PPT chapters.
- If thesis has explicit chapters (第一章...第四章): map directly to PPT chapters
- If thesis has no chapters (like a conference paper with sections): group related sections into 3-5 logical chapters for the PPT
- Do NOT invent arbitrary chapter divisions that don't match the thesis logic
- The PPT chapter structure should feel natural to someone who has read the thesis
2.1 First Pass: Structure Proposal
After reading the thesis, propose the high-level structure directly in conversation:
📐 PPT 结构提案
根据你的论文结构，我建议这样安排：
总页数：42 页（约 20 分钟答辩）
| 章 | 标题 | 页数 | 对应论文 | 说明 |
|---|
| 一 | 研究背景与科学问题 | 8页 | 第1章 | 背景+命题+假设+创新点 |
| 二 | 数据构建与描述性分析 | 7页 | 第2章 | 数据来源+特征工程+时序总览 |
| 三 | 演化模式与驱动机制 | 15页 | 第3章 | H1+H2+H3 三个假设检验 |
| 四 | 结论与展望 | 5页 | 第4章 | 主要结论+局限+展望+成果 |
你觉得这个结构可以吗？ 可以告诉我：
- "第三章太长了，拆成两章"
- "加一章文献综述"
- "总页数控制在35页以内"
Wait for user to confirm or adjust. Loop until structure is approved.
2.2 Second Pass: Per-Section Detail
Once chapter structure is approved, expand each chapter in conversation (not in a file):
📋 第一章 详细安排（8页）
| 页码 | 版式 | 标题 | 内容要点 |
|---|
| P3 | 章节分隔 | 一、研究背景与科学问题 | — |
| P4 | 左文右图 | 寒武纪辐射与软体动物的演化窗口 | 演化窗口介绍 + 地质年代图 |
| P5 | 纯文段 | 经典命题：Disparity vs. Diversity | 形态多样性与丰富度争论 |
| P6 | 纯文段 | 驱动机制之一：外源突变 | Sinsk 事件背景 |
| P7 | 纯文段 | 驱动机制之二：系统发育约束 | OU 过程假说 |
| P8 | 列表 | 现有研究的四点不足 | 4个gap |
| P9 | 表格 | 研究目标与三个核心假设 | H1/H2/H3 表格 |
| P10 | 列表 | 论文的主要创新 | 5个创新点 |
这章的安排可以吗？ 可以说：
- "P5和P6合并成一页"
- "P9加一列'若成立则说明'"
- "ok，继续下一章"
Present one chapter at a time. Wait for approval before showing the next chapter.
2.3 Third Pass: Final Confirmation
After all chapters are individually approved, show a complete summary in conversation:
✅ 最终大纲确认
| 章 | 页码范围 | 页数 | 版式分布 |
|---|
| 封面+目录 | P1–P2 | 2 | cover, toc |
| 一 研究背景 | P3–P10 | 8 | 分隔×1, 左文右图×1, 纯文段×3, 列表×1, 表格×1, 列表×1 |
| 二 数据构建 | P11–P17 | 7 | 分隔×1, ... |
| 三 演化机制 | P18–P32 | 15 | 分隔×1, ... |
| 四 结论展望 | P33–P37 | 5 | 分隔×1, ... |
| 致谢 | P38 | 1 | thanks |
| 合计 | | 38页 | |
确认后我将开始生成 beamer LaTeX 代码。确认吗？
HARD GATE: Do NOT proceed to Phase 3 until user explicitly confirms the final summary.
2.4 Save to outline.md
Only after final confirmation, save the approved structure to outline.md for Phase 3 reference. This file is for the AI's internal use — user has already approved everything in conversation.
Why In-Conversation Instead of File
- Users who don't know markdown can follow along naturally in chat
- Iterative refinement is faster (no "go check that file" round-trip)
- Each chapter gets individual attention
Layout Selection Rules (used in 2.2 per-page assignment)
- Each chapter start →
section-divider
- Core formula/model definition →
formula
- Multi-row data comparison →
table
- High-information figure (multi-panel, heatmap) →
full-image
- Text-primary with supporting figure →
text-left-image-right
- Figure-primary with interpretation →
image-left-text-right
- Pure concept/background →
text-only
- Chapter-end with clear conclusion →
conclusion-box
- Between chapters →
transition
- Parallel bullet points →
list
Rhythm Constraints
- No 3 consecutive pages with same layout
- Each chapter uses at least 3 different layouts
- Total: 35–50 pages (defense), 25–35 (proposal), 15–25 (conference)
Phase 3: Content Generation
- Copy
assets/beamerthemeAcademic.sty to current directory.
- Generate
defense.tex file header. Read references/tex-header.md for template.
- For each page in
outline.md:
- Load layout skeleton from
references/layouts.md (find section by layout id)
- Fill slots with thesis content + extracted materials
- Close with
\end{document}.
Critical: Section Divider = Outline Page (NOT full-color page)
The section-divider page should be an Outline page that shows all chapters with the current
chapter highlighted, NOT a full-color page with just a number. Use \tableofcontents[currentsection]
or equivalent tabbing layout where current chapter is bold/colored and others are grayed out.
Example (每章开头的分隔页):
\begin{frame}
\frametitle{Outline}
\tableofcontents[currentsection]
\end{frame}
Critical: TOC Page Format
The TOC page (P2) must use Chinese numbering with em-dash subtitles:
\begin{frame}
\frametitle{汇报提纲}
\vskip0.3cm
{\footnotesize
\begin{tabbing}
\hspace{0.4cm}\=\hspace{0.6cm}\=\kill
\textbf{\color{accentcolor}一}\>\textbf{研究动机}\,——\,为什么需要新的序列建模方案\\[8pt]
\textbf{\color{accentcolor}二}\>\textbf{模型架构}\,——\,Transformer 的核心设计\\[8pt]
\textbf{\color{accentcolor}三}\>\textbf{实验结果}\,——\,翻译质量与消融分析\\[8pt]
\textbf{\color{accentcolor}四}\>\textbf{总结与展望}\,——\,贡献与未来方向\\
\end{tabbing}
}
\end{frame}
Critical: Figure Extraction from PDF
NEVER use full-page PDF screenshots as figures. When source is PDF:
- Use
pdfimages -all paper.pdf materials/figures/ to extract embedded vector/raster images
- If
pdfimages not available, use mutool extract or Python PyMuPDF
- If only
pdftoppm is available, crop the figure region ONLY:
- First identify figure bounding box coordinates
- Use Python PIL to crop the figure out of the page image
- Remove surrounding text, page numbers, captions
- Quality check: if extracted figure contains visible paper text around it, it's WRONG — re-crop
- For well-known papers (Transformer, ResNet, etc.), consider re-drawing key diagrams with tikz
Critical: Anti-AI Writing Style (NO Bullet List Abuse)
The #1 sign of AI-generated slides is overuse of \begin{itemize} and uniform page structure.
Core rules:
- Each page COMBINES multiple elements (段落+keybox, 段落+公式+段落, 段落+表格+结论)
- Adjacent pages MUST use different composition patterns
\begin{itemize} is BANNED. Only \enumerate with intro paragraph allowed- 80% of pages use paragraph-style writing, not bullet points
- Use inline patterns:
$\bullet$ \textbf{term}, \alert{keyword}, \textbf{title}\,——\,explanation
Read references/writing-style.md for 6 concrete composition patterns with LaTeX code examples.
Content Quality Rules
| Constraint | Value |
|---|
| Text per page (text-only) | 150–200 chars |
| Text per page (with figure) | 100–150 chars |
| Equations per page | max 2 |
| Table rows | 3–8 |
\alert{} keywords per page | 1–2 |
| Page structure | COMBINE multiple elements (see writing-style.md) |
\itemize | BANNED |
Section Divider = Outline Page (Enforced)
Every chapter boundary MUST use an Outline page (\tableofcontents[currentsection]).
This provides visual rhythm and structural navigation for the audience.
Anti-AI Title & Content Check
Before finalizing, check all titles and content. Read references/writing-style.md for the full red-flag list.
Quick check: "这个标题/段落像答辩学生写的还是 AI 写的？" 如果像 AI，改到像人。
Figure & Table Numbering
All figures and tables in the presentation MUST be numbered sequentially:
- Figures:
图 1, 图 2, 图 3... (using \figcap{图 1\;描述文字})
- Tables: in frame title or above table, mark as
表 1, 表 2...
Example:
\figcap{图 1\;Transformer 编码器--解码器架构}
\figcap{图 2\;多头注意力并行投影机制}
Table title pattern:
\frametitle{机器翻译 BLEU 对比（表 2）}
% or inside the frame:
{\small\textbf{表 1}\;不同层类型的复杂度对比}
Numbering must be consistent throughout — do not skip or repeat numbers.
Phase 4: Compilation & Layout Verification
4.1 Compile
xelatex -interaction=nonstopmode defense.tex && xelatex -interaction=nonstopmode defense.tex
On failure: read defense.log, fix common issues (missing image, font, overfull hbox), retry up to 3 times.
If user has no LaTeX environment, skip compilation and deliver .tex + .sty + materials/figures/.
4.2 Layout Bug Detection
After compilation, check defense.log for these common layout issues:
| Symptom | Cause | Fix |
|---|
Overfull \vbox on frame | Content exceeds page height | Reduce text, split into 2 pages, or shrink font |
Overfull \hbox with image | Image too wide for column | Add keepaspectratio, reduce width |
| Image overlaps text in columns | \column width sum > \textwidth | Ensure left + right column ≤ 1.0 |
| tikz overlay covers text | [remember picture, overlay] node position wrong | Adjust yshift/xshift values |
| Text runs below frame | Too many paragraphs | Cut to 150-200 chars or split page |
Proactive overlap prevention (apply during Phase 3 content generation):
- For
text-left-image-right: left text ≤ 150 chars, image height ≤ 3.4cm per image
- For
image-left-text-right: right text ≤ 120 chars, image height ≤ 0.60\textheight
- For
full-image: use only tikz overlay positioning, no surrounding text except \figcap
- For
formula: max 2 equations, with \vskip0.1cm spacing between
- Never put more than 3
\vskip commands in one frame (sign of overstuffing)
If overlap detected in compiled PDF (user reports "P7图文重叠了"):
- Identify the frame in
.tex
- Check: is text too long? Is image too tall? Are column widths correct?
- Apply fix: reduce text / shrink image / split into 2 pages
- Recompile and verify
Phase 5: Interactive Editing (Guided Choices)
Present result:
✅ PDF 已生成：./defense.pdf（共 XX 页，预计答辩时长 XX 分钟）
说修改意见，或说"满意"结束。
5.1 Guided Modification (Never Let User Struggle to Express)
When user gives vague feedback, offer concrete choices instead of asking them to describe:
| User says | Respond with choices |
|---|
| "这页不好看" | "你觉得是：A. 文字太密想拆成两页？B. 图太小想换成满版图？C. 想换个版式？" |
| "这里有点奇怪" | "我看到可能的问题：A. 图文重叠了 B. 文字太学术想简化 C. 想加个过渡说明？" |
| "第三章不太行" | "第三章目前15页。你想：A. 整体缩减（砍到10页）？B. 某几页太密拆开？C. 补一页总结？" |
| "改好看点" | "我可以：A. 加几页满版图让节奏更松 B. 关键结论用高亮框突出 C. 换个配色？" |
Principle: Always give 2–3 concrete options with preview of effect. User picks, not describes.
5.2 Modification Execution
| Type | Action |
|---|
| Single page content edit | Edit corresponding \begin{frame}...\end{frame} |
| Add/remove page | Update outline.md, regenerate affected section |
| Global style change | Modify .sty or header |
| Layout switch | Replace frame with different layout skeleton |
After each edit, recompile and present again. Loop until user says done.
Phase 6: Speaker Notes & Rehearsal Support (Optional)
After user confirms the slides are satisfactory, offer:
需要我帮你生成讲稿和配速建议吗？可以帮助你控制答辩节奏。
If user accepts, generate notes.md:
