# How to see explicit paragraph markings in compiled document?

Sometimes I find it hard to keep track of where new paragraphs begin in my document. I have a lot of display equations and \noindent commands, as well as line breaks, blank lines, figures, etc. I can't tell precisely which of these elements are together in one paragraph.

Is there a way to see explicitly in my document (in the compiled pdf) where new paragraphs begin? I think this would be useful for debugging.

• One way would be to remove the \noindent commands, which should be used extremely rarely in most documents, anyway. – Paul Gessler Jan 8 '15 at 21:25
• If you can't tell where the paragraphs begin and end, how will your reader know? – musarithmia Jan 8 '15 at 21:39
• Paragraphs should simply be separated, in the input file, by a blank line. If you're using lots of explicit line breaks by \\ and using lots of \noindent, you're on the wrong road. There should be no blank line after a displayed equation. – egreg Jan 8 '15 at 21:43
• @becko if a new paragraph shouldn't be starting, then don't start one. (That is, don't leave a blank line in the source. If you want the whitespace for readability in your source, use comment characters to prevent a new paragraph.) – Paul Gessler Jan 8 '15 at 21:45
• It's not clear why you have a problem. In the source paragraphs are clearly marked by a blank line, and in the typeset result by a paragraph indent. If the paragraphs are not easily visible something is wrong, but you don't give any example so it is hard to say what is wrong. – David Carlisle Jan 8 '15 at 22:35

Note that a blank line in the source file should never be used for cosmetic arrangement of the source file. It is parsed as a TeX instruction and creates the token \par exactly as if you typed \par explicitly. So a blank line should only be used in the source at the end of a paragraph.
