xetex: Compile a PDF document, exiting if errors occur.
$ xetex -halt-on-error ${source-tex}
try on your machine
The command "xetex" is a command-line tool used for typesetting documents written in LaTeX or TeX. In this command, it is being used with the "-halt-on-error" option, which tells XeTeX to stop processing the document if it encounters an error.
"${source-tex}" refers to a variable, and the value of this variable is expected to be the name or path of the LaTeX or TeX source file that you want to process.
So, when you run this command, XeTeX will attempt to compile the specified source file. If any errors occur during the compilation, XeTeX will halt and display the error message, allowing you to debug and fix the issue before proceeding.
