Use Pandoc's LaTeX image with LuaLaTeX and TeX Gyre Fonts

[Vincent Tam]

I wonder if there's a way to use pandoc's LaTeX image with LuaLaTeX and TeX Gyre Fonts.

I tried setting up this Dockerfile:

FROM pandoc/latex:2.11.1.1

RUN apk add --no-cache \

    chromium \

    nss \

    freetype \

    freetype-dev \

    harfbuzz \

    ca-certificates \

    ttf-freefont \

    nodejs \

    yarn \

    ttf-ubuntu-font-family

# Tell Puppeteer to skip installing Chrome. We'll be using the installed package.

ENV PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=true \

    PUPPETEER_EXECUTABLE_PATH=/usr/bin/chromium-browser \

    PATH="/data/node_modules/.bin:${PATH}"

# Add user so we don't need --no-sandbox.

RUN addgroup -S pptruser && adduser -S -g pptruser pptruser \

    && mkdir -p /home/pptruser \

    && chown -R pptruser:pptruser /home/pptruser \

    && chown -R pptruser:pptruser /data

# Puppeteer v5.1.0 works with Chromium 84.

RUN yarn add eslint puppeteer mermaid-filter

# Install Tex Gyre Termes font

RUN tlmgr install tex-gyre tex-gyre-math

# Install Noto Color Emoji

RUN mkdir -p /usr/share/fonts/truetype/noto \

    && cd /usr/share/fonts/truetype/noto \

    && wget https://raw.githubusercontent.com/googlefonts/noto-emoji/master/fonts/NotoColorEmoji.ttf \

    && wget https://raw.githubusercontent.com/googlefonts/noto-emoji/master/fonts/NotoEmoji-Regular.ttf \

    && fc-cache -fv

# Run everything after as non-privileged user.

USER pptruser

WORKDIR /home/pptruser

COPY src/puppeteerConfigFile.json /home/pptruser/.puppeteer.json

When I want to use compile a markdown file to PDF with LuaLaTeX as the PDF engine with mainfont: TeX Gyre Termes at the top, I got the following error.

This is LuaHBTeX, Version 1.12.0 (TeX Live 2020)

I tried searching for a way to fix this, but I couldn't find a successful example.

In pandoc's LaTeX image, TeXLive 2020 is installed under /opt/texlive/, whose write access requires root privileges.  I wonder if there's a way to use TeX Gyre * fonts with LuaLaTeX as the PDF engine.

I think you should better ask on TeX Stack Exchange. This looks like pretty low-level issue on lualatex side.

Thanks for response.  I did type it once on TeX.SE, and after that, I had found the solution that I implemented at commit VincentTam/pandoc-mermaid-docker@d86343f0.  In short, adding

chmod o+w /opt/texlive/texdir/texmf-var

resolves the problem.
