Correct word-count of a LaTeX document

Correct word-count of a LaTeX document

Counting words in a LaTeX document can be a bit tricky because LaTeX documents contain a lot of markup and commands that aren't part of the actual text content. Here are some methods to accurately count words in a LaTeX document:

1. Using TeXcount

TeXcount is a Perl script specifically designed to count words in LaTeX documents. It is one of the most accurate tools for this purpose.

Installation

  1. Install TeXcount:
    • On macOS with Homebrew:
      brew install texcount
    • On Debian-based Linux distributions:
      sudo apt-get install texlive-extra-utils
    • On Windows, you can download TeXcount from CTAN or use TeX Live.

Usage

  1. Count Words:

    texcount -total yourfile.tex
    • -total: Provides the total word count including all sections.
    • You can also use various options like -brief, -html, etc., depending on the output format you need.

2. Using LaTeX Package wordcount

The wordcount LaTeX package can be used within the document to count words.

Installation

  • Make sure you have the wordcount package installed with your LaTeX distribution.

Usage

  1. Include the Package:

    \usepackage{wordcount}

  2. Count Words in the Document:

    • Add the command to your document where you want the count:

      \begin{document} \wordcount

    • Note: This method counts only the words that are visible in the final PDF output.

3. Using a LaTeX Editor

Some LaTeX editors have built-in word count functionalities that can count words in the final document.

Example Editors

  • TeXShop (macOS): Provides word count functionality in the menu.
  • TeXworks: Includes a word count feature under the Tools menu.
  • Overleaf: Shows word count in the project details on the right panel.

4. Using External Tools

For more control or additional processing, you might use a combination of tools:

  1. Convert LaTeX to Plain Text:

    • Use tools like detex to strip LaTeX commands:

      detex yourfile.tex | wc -w

    • Note: detex might need to be installed separately.

  2. Using Pandoc:

    • Convert your LaTeX document to plain text or other formats for word counting:
      pandoc yourfile.tex -t plain | wc -w

Summary

  • TeXcount: Most accurate and recommended tool for LaTeX word count.
  • LaTeX Package wordcount: Useful for counting within the document.
  • LaTeX Editors: Built-in functionality for word counting.
  • External Tools: detex and pandoc for converting LaTeX to plain text.

Choose the method that best suits your needs based on the complexity of your document and the precision required.
