# Build the complete book as a single PDF (ElegantBook design, teal/cyan theme).

# Requirements: pandoc, xelatex, ElegantBook class, rsvg-convert (librsvg),

# fonts: Menlo / Arial Unicode MS (macOS) — Linux auto-falls back

# to DejaVu Sans/Mono and Noto CJK (see preamble.tex).

# Usage: cd book && bash build_pdf.sh

# Note: chapter/section numbers come from the document class; source headings

# carry no manual numbers (see git history for the de-numbering pass).

# ── Runtime environment tweaks (harmless on macOS, needed on Linux/TeX Live) ──

# 1) This book is large enough to exhaust XeTeX's default main memory

# ("TeX capacity exceeded ... [main memory size=5000000]") during page

# output. main_memory is baked into the format at dump time, but

# extra_mem_top/bot extend an existing format at runtime — so we bump them

# here instead of rebuilding the xelatex format.

export extra_mem_top=8000000

export extra_mem_bot=8000000

# 2) The mac-only monospace font (Menlo) is probed with \IfFontExistsTF in

# preamble.tex. On systems without it, kpathsea otherwise spawns METAFONT to

# build a Menlo.tfm (slow, noisy, always fails) before the DejaVu Sans Mono

# fallback engages. Disabling on-the-fly TFM creation makes the probe return

# immediately with the correct "not found" result.
