FAQs

How to use XeLaTeX or LuaLaTeX instead of pdfLaTeX?

By default, this action uses pdfLaTeX. If you want to use XeLaTeX or LuaLaTeX, you can set the args to -xelatex -file-line-error -interaction=nonstopmode or -lualatex --file-line-error --interaction=nonstopmode respectively. Alternatively, you could create a .latexmkrc file. Refer to the latexmk document for more information.

How to enable --shell-escape?

To enable --shell-escape, you should add it to args. For example, set args to -pdf -file-line-error -interaction=nonstopmode -shell-escape when using pdfLaTeX.

Where is the PDF file? How to upload it?

The PDF file will be in the same folder as that of the LaTeX source in the CI environment. It is up to you on whether to upload it to some places. Here are some example.

• You can use @actions/upload-artifact to upload PDF file to the workflow tab.
• You can use @actions/upload-release-asset to upload PDF file to the Github Release.
• You can use normal shell tools such as scp/git/rsync to upload PDF file anywhere. For example, you can git push to the gh-pages branch in your repo, so you can view the document using Github Pages.
