TexStripper

Motivation

Grammarly is a popular tool for checking grammar and spelling errors in English text. However, LaTeX documents are not well supported by Grammarly, as LaTeX commands will interfere with the grammar checking process. Removing LaTeX syntax from the document is tiresome. TexStripper aims to provide a simple tool to strip LaTeX syntax from the document, so that the document can be checked by Grammarly.

Installation and Usage

1. Clone the repository:

git clone https://github.com/AllenYolk/tex-stripper.git

2. Run the script with Python:

python texstripper/cli.py -s <path_to_source_file> -o <path_to_output_file>

Functionality

Read TeX scripts recursively according to the \input{...} and \include{...} commands.

• So, you only need to run texstripper once on main.tex, and all the subfiles will be processed.

Remove the following LaTeX components from a .tex file:

• Comments: % ..., both between lines and inline
• Preamble: the part before \begin{document}
• Authors: \author{...}
• Labels: \label{...}
• Bibliography: \bibliography{...}, \bibliographystyle{...}
• Miscellaneous inline commands: \maketitle, \linenumbers, \nolinenumbers, \newpage, ...
  • See texstripper/tex_utils/remove.py for more details.

Replace the following LaTeX components with a placeholder:

• Citations: \cite{...} or ~\cite{...}
• References: \ref{...} or ~\ref{...}
• Equation references: \eqref{...} or ~\eqref{...}
• Named references: \nameref{...} or ~\nameref{...}
• Inline math: $...$
• Math blocks: \begin{equation} ... \end{equation}, \begin{align} ... \end{align}
• Input & include: \input{...}, \include{...}

Unwrap the following LaTex commands while keeping the contents:

• Title: \title{...}
• Document: \begin{document} ... \end{document}
• Abstract: \begin{abstract} ... \end{abstract}
• Part & chapter & section & paragraph: \part{}, \chapter{...}, \section{...}, \subsection{...}, \subsubsection{...}, \paragraph{...}, \subparagraph{...}
• Bold: \textbf{...}
• Italic: \textit{...}
• Underline: \underline{...}, \uline{...}
• Emphasis: \emph{...}
• Color: \textcolor{...}{...}; only the second argument is kept
• Footnote: \footnote{...}
• List: \begin{itemize} ... \item ... \end{itemize}, \begin{enumerate} ... \item ... \end{enumerate}; only the list items are kept
• Table: \begin{table} ... \end{table}; only the caption is kept
• Figure: \begin{figure} ... \end{figure}; only the caption is kept
• Pseudocode: \begin{algorithm} ... \end{algorithm}; only the caption is kept

TODO

• Add setup.py to make texstripper a globally available command-line tool.
