acl-org/aclpubcheck

ACL pubcheck is a Python tool that automatically detects font errors, author formatting errors, margin violations, outdated citations as well as many other common formatting errors in papers that are using the LaTeX sty file associated with ACL venues. The script can be used to check your papers before you submit to a conference. (We highly recommend running ACL pubcheck on your papers pre-submission—a well formatted paper helps keep the reviewers focused on the scientific content.) However, its main purpose is to ensure your accepted paper is properly formatted, i.e., it follows the venue's style guidelines. The script is used by the publication chairs at most ACL events to check for formatting issues. Indeed, running this script yourself and fixing errors before uploading the camera-ready version of your paper will often save you a personalized email from the publication chairs.

Once installed, you can use apply it on a PDF:

Replace PAPER_TYPE with one of (1) long, (2) short, (3) demo, depending on the type of paper you have accepted. Then, change path/to/paper.pdf to be the path to your paper. For example:

If you find that ACL pubcheck gives you a margin error due to a figure that runs into the margin, you can often fix the problem by applying the adjustbox package. Additionally, if the margin error is caused by an equation, then it may help to break the equation over two lines.
