LaTeX Build Automation

LaTeX Build Automation

Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.

When to Use This Skill

Use this skill when:

• Compiling LaTeX documents
• Setting up live preview with auto-rebuild
• Managing multi-file projects
• Troubleshooting build failures
• Cleaning build artifacts
• Automating compilation workflows

Quick Reference

Why latexmk?

Industry standard build tool:

• Auto-detects dependencies (bibliography, index, etc.)
• Runs correct number of times (handles cross-references)
• Live preview mode watches for file changes
• Works with Skim for SyncTeX auto-reload
• Bundled with MacTeX (no separate install needed)

Basic Usage

One-Time Build

latexmk -pdf document.tex
# Result: document.pdf created

Live Preview (Watch Mode)

latexmk -pvc -pdf document.tex

# What happens:
# - Compiles document initially
# - Watches for file changes
# - Auto-recompiles when files change
# - Auto-reloads PDF in Skim viewer

Stop watching: Press Ctrl+C

Quick Reference Card

# Build once
latexmk -pdf document.tex

# Live preview (watch mode)
latexmk -pvc -pdf document.tex

# Build with SyncTeX
latexmk -pdf -synctex=1 document.tex

# Clean artifacts
latexmk -c              # Keep PDF
latexmk -C              # Remove PDF too

# Force rebuild
latexmk -gg -pdf document.tex

# Non-interactive (for CI)
latexmk -pdf -interaction=nonstopmode document.tex

Build Checklist

• Verify latexmk installed: which latexmk
• Test basic build: latexmk -pdf document.tex
• Enable SyncTeX: Add -synctex=1 flag
• Test live preview: latexmk -pvc -pdf document.tex
• Configure Skim for auto-reload
• Create Makefile for common tasks (optional)
• Create .latexmkrc for project-specific settings (optional)
• Test clean: latexmk -c removes artifacts

Troubleshooting

Post-Execution Reflection

After this skill completes, check before closing:

1. Did the command succeed? — If not, fix the instruction or error table that caused the failure.
2. Did parameters or output change? — If the underlying tool's interface drifted, update Usage examples and Parameters table to match.
3. Was a workaround needed? — If you had to improvise (different flags, extra steps), update this SKILL.md so the next invocation doesn't need the same workaround.

Only update if the issue is real and reproducible — not speculative.
