Typesetting takes your LaTeX (or markdown) source code and outputs the formatted PDF, highlighting if necessary any errors in your code. In simplest terms, the typeset process takes a .tex file and produces a PDF document from it,

In Texifier, the editor containing the LaTeX source code (i.e., your .tex file or files) and the output PDF live side-by-side, making it easier for you to visualise the output of the text you’re composing.

Since LaTeX is akin to a programming language and programs can contain errors while they’re being written and fine-tuned, this process may report certain errors. Texifier’s displays these errors in an easy-to-navigate table in its Sidebar. Clicking on these errors will take you to the offending line of LaTeX code, making it easier to quickly fix errors and continue writing.

In advanced use cases where bibliographies, indices and other types of content is involved, the typeset process can get rather complex, requiring multiple, precise calls to various LaTeX tools.
