LaTeX Environment Setup

You are helping a researcher set up or fix their LaTeX compilation environment. Do NOT hardcode package lists — detect and install what's actually needed.

Step 1: Detect Current State

Before installing anything:

1. **Check installed TeX distribution**:

   which pdflatex && pdflatex --version
   which xelatex && xelatex --version
   which lualatex && lualatex --version

2. **Check bibliography processor**:

   which biber && biber --version
   which bibtex && bibtex --version

3. **Check package manager**:

   which tlmgr && tlmgr --version

Step 2: Analyze the Project

Read the main .tex file to determine requirements:

1. **Document class**: `\documentclass{article}`, `\documentclass{IEEEtran}`, etc. 2. **Bibliography system**:

• `\usepackage{biblatex}` → needs `biber`
• `\usepackage{natbib}` or `\bibliographystyle{...}` → needs `bibtex`

3. **Required packages**: extract from all `\usepackage{...}` declarations 4. **Special requirements**: TikZ, minted (needs pygments), algorithm2e, etc.

Step 3: Venue Template Detection

If the user mentions a venue, search for the official template:

• Download from the venue's official website (NOT third-party mirrors)
• Check if the template specifies a required TeX distribution or class
• Note any venue-specific compilation instructions

Common venues and their requirements: | Venue | Class | Bib system | Notes | |-------|-------|-----------|-------| | CVPR/ECCV | Custom class file | bibtex | Usually provided in template | | NeurIPS | neurips_20XX.sty | natbib + bibtex | Style file changes yearly | | ICLR | iclr20XX_conference.sty | natbib + bibtex | OpenReview format | | ACL/EMNLP | acl.cls | bibtex | ACL Anthology format | | IEEE | IEEEtran.cls | bibtex | Column formatting specific | | Springer | llncs.cls | bibtex or biblatex | Depends on series |

Step 4: Install Missing Components

Based on analysis, install only what's missing:

On Ubuntu/Debian

# Base installation (if nothing installed)
sudo apt install texlive-base texlive-latex-recommended

# Common extras
sudo apt install texlive-latex-extra  # most \usepackage needs
sudo apt install texlive-fonts-recommended texlive-fonts-extra
sudo apt install texlive-bibtex-extra biber  # if biblatex used
sudo apt install texlive-science  # algorithm2e, etc.

On macOS

# Full installation (recommended)
brew install --cask mactex

# Minimal
brew install --cask basictex
sudo tlmgr update --self
sudo tlmgr install <package-name>

Individual packages via tlmgr

# If specific packages are missing
sudo tlmgr install <package-name>

Step 5: Configure Compilation

Set up the correct compilation pipeline:

For bibtex projects

pdflatex main.tex
bibtex main
pdflatex main.tex
pdflatex main.tex

For biblatex/biber projects

pdflatex main.tex
biber main
pdflatex main.tex
pdflatex main.tex

Common compilation issues

• **Missing .bib file**: check `\bibliography{...}` path is correct
• **Undefined citations**: run bibtex/biber + pdflatex twice
• **Missing packages**: install via tlmgr, not apt (apt packages are coarse-grained)
• **Font errors**: install texlive-fonts-extra
• **TikZ externalize errors**: ensure write18 is enabled

Step 6: Verify Setup

After configuration:

1. Run the full compilation pipeline 2. Check the PDF opens correctly 3. Verify bibliography entries appear 4. Check for any remaining warnings in the .log file

Output Format

Produce: 1. **Current state**: what's installed, what's missing 2. **Project requirements**: detected from .tex files 3. **Installation commands**: only what's needed, OS-specific 4. **Compilation command**: the exact pipeline for this project 5. **Verification**: confirm successful compilation
