name: LaTeX slug: latex version: 1.0.0 description: Write LaTeX documents with correct syntax, packages, and compilation workflow. homepage: https://clawic.com/skills/latex metadata: clawdbot: emoji: 📐 os: - linux - darwin - win32 displayName: LaTeX

Special Characters

  • Reserved chars need escape: \# \$ \% \& \_ \{ \} \textbackslash
  • Tilde as character: \textasciitilde not \~ (that's an accent)
  • Caret: \textasciicircum not \^
  • Backslash in text: \textbackslash not \\ (that's line break)

Quotes & Dashes

  • Opening quotes: `` not "; closing: ''—never use straight " quotes
  • Hyphen -, en-dash -- (ranges: 1--10), em-dash --- (punctuation)
  • Minus in math mode: $-1$ not -1 in text

Math Mode

  • Inline: $...$ or \(...\); display: \[...\] or equation environment
  • Text inside math: $E = mc^2 \text{ where } m \text{ is mass}$
  • Multiline equations: align environment, not multiple equations
  • \left( ... \right) for auto-sizing delimiters—must be paired

Spacing

  • Command followed by text needs {} or \ : \LaTeX{} or \LaTeX\ is
  • Non-breaking space: ~ between number and unit: 5~km
  • Force space in math: \, thin, \: medium, \; thick, \quad \qquad

Packages

  • \usepackage order matters—hyperref almost always last
  • inputenc + fontenc for UTF-8: \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc}
  • graphicx for images, booktabs for professional tables, amsmath for advanced math
  • microtype for better typography—load early, subtle but significant improvement

Floats (Figures & Tables)

  • [htbp] suggests placement: here, top, bottom, page—not commands
  • LaTeX may move floats far from source—use [H] from float package to force
  • Always use \centering inside float, not center environment
  • Caption before \label—label references the last numbered element

References

  • Compile twice to resolve \ref and \pageref—first pass collects, second uses
  • \label immediately after \caption or inside environment being labeled
  • For bibliography: latex → bibtex → latex → latex (4 passes)
  • hyperref makes refs clickable—but can break with some packages

Tables

  • tabular for inline, table float for numbered with caption
  • Use booktabs: \toprule, \midrule, \bottomrule—no vertical lines
  • @{} removes padding: \begin{tabular}{@{}lll@{}}
  • Multicolumn: \multicolumn{2}{c}{Header}; multirow needs multirow package

Images

  • Path relative to main file or set with \graphicspath{{./images/}}
  • Prefer PDF/EPS for pdflatex/latex; PNG/JPG for photos
  • \includegraphics[width=0.8\textwidth]{file}—no extension often better

Common Errors

  • Overfull hbox: line too long—rephrase, add \- hyphenation hints, or allow \sloppy
  • Missing $: math command used in text mode
  • Undefined control sequence: typo or missing package
  • \include adds page break, \input doesn't—use \input for fragments

Document Structure

  • Preamble before \begin{document}—all \usepackage and settings
  • \maketitle after \begin{document} if using \title, \author, \date
  • article for short docs, report for chapters without parts, book for full books
