LaTeX Editing

PaperPilot's editor provides a rich LaTeX editing experience with intelligent features that understand your document structure.

Syntax Highlighting

The editor uses semantic highlighting to make your LaTeX code readable:

\documentclass{article}
\usepackage{graphicx}
\usepackage{amsmath}

\title{My Research Paper}
\author{Jane Doe}
\date{\today}

\begin{document}

\maketitle

\section{Introduction}

This is an example of LaTeX syntax highlighting in action.
Mathematical expressions like $E = mc^2$ are highlighted differently.

\begin{equation}
    \int_{0}^{\infty} e^{-x^2} dx = \frac{\sqrt{\pi}}{2}
\end{equation}

% This is a comment - grayed out for easy identification

\end{document}

Color Scheme

Autocomplete

Intelligent suggestions as you type:

Command Autocomplete

Start typing a command and suggestions appear:

\sec...
↓
\section{}
\subsection{}
\subsubsection{}

Environment Autocomplete

Type \begin{ to see available environments:

\begin{eq...
↓
equation
equation*
eqnarray

When you select an environment, the closing \end{} is inserted automatically.

Custom Definitions

The editor learns your document:

• Custom commands - \newcommand definitions appear in suggestions
• Labels - \label{} names are suggested for \ref{} and \cite{}
• Bibliography keys - BibTeX keys from your .bib files

Snippets

Speed up common patterns with built-in snippets:

\begin{figure}[htbp]
    \centering
    \includegraphics[width=0.8\textwidth]{|cursor|}
    \caption{Enter caption}
    \label{fig:label}
\end{figure}

\begin{table}[htbp]
    \centering
    \begin{tabular}{|c|c|c|}
        \hline
        A & B & C \\
        \hline
        |cursor| \\
        \hline
    \end{tabular}
    \caption{Enter caption}
    \label{tab:label}
\end{table}

\begin{align}
    |cursor|
\end{align}

\frac{numerator}{denominator}

\begin{itemize}
    \item |cursor|
\end{itemize}

Bracket Matching

The editor highlights matching delimiters:

• Braces { } - Command arguments
• Brackets [ ] - Optional arguments
• Parentheses ( ) - Grouping
• Environment markers - \begin{} and \end{} pairs

Code Folding

Collapse sections to focus on what matters:

Foldable Regions

• Sections - Collapse entire sections and subsections
• Environments - Fold figure, table, equation blocks
• Preamble - Collapse everything before \begin{document}
• Custom - Use %region and %endregion comments

%region Preamble
\documentclass{article}
\usepackage{...}
% ... many packages ...
%endregion

\begin{document}

Fold Controls

Find and Replace

Powerful search with regex support:

Multi-Cursor Editing

Edit multiple locations simultaneously:

Error Indicators

The editor shows LaTeX issues inline:

• Red underline - Syntax errors
• Yellow underline - Warnings (undefined references, etc.)
• Info icons - Suggestions for improvement
