LaTeX Advanced Typesetting: Professional Document Production

Introduction

LaTeX remains the gold standard for professional document typesetting, particularly in academia, science, and engineering. While basic LaTeX documents are straightforward to create, truly professional output requires understanding advanced typesetting techniques.

In 2026, LaTeX continues to evolve with new packages and workflows, particularly for integration with modern tools like VS Code, Git, and continuous document building. This guide covers advanced typesetting techniques that will help you create publication-quality documents.

Advanced Macro Writing

Defining Custom Commands

% Basic custom command
\newcommand{\pkg}[1]{\texttt{#1}}
\newcommand{\file}[1]{\texttt{#1}}

% Command with optional argument
\newcommand{\code}[2][python]{\texttt{#2}}

% Command with multiple arguments
\newcommand{\highlight}[2]{\textbf{#1: #2}}

% Robust command for moving arguments
\DeclareRobustCommand{\macroname}[1]{%
  \textit{#1}%
}

Creating Environments

% Custom theorem environment
\newtheoremstyle{breaking}
  {3pt}% Space above
  {3pt}% Space below
  {\itshape}% Body font
  {}% Indent amount
  {\bfseries}% Head font
  {.}% Punctuation after head
  {.5em}% Space after head
  {}%

\theoremstyle{breaking}
\newtheorem{break theorem}{\theoremname}[section]

Conditional Logic

% Define conditionals
\newif\ifdraft
\drafttrue  % or \draftfalse

% Use conditional
\ifdraft
  \usepackage{draftwatermark}
  \SetWatermarkText{DRAFT}
\fi

% Check for empty arguments
\makeatletter
\newcommand{\ifempty}[3]{%
  \ifx#1\@empty #3\else #2\fi
}
\makeatother
