LaTeX Editor #

Write your manuscripts in a comfortable web editor and compile to PDF with one click. No local TeX installation required.

What It Is #

The Composr page is a LaTeX editor integrated with cloud compilation. It’s like Overleaf but connected to your Apex Scholar workspace.

Why Use It #

• No need to install TeX Live on your computer
• Access your source from anywhere
• PDFs are generated quickly via GitHub Actions
• Your .tex files are versioned in your project

Quick Start #

1. Click Composr in the sidebar
2. Click New Document
3. Choose a template (Article, Report, Blank)
4. Start writing
5. Click Compile
6. Download the PDF

Including Figures #

Upload figures (PNG, JPG, PDF) to Resources first. Then include them:

\begin{figure}[h]
  \centering
  \includegraphics[width=0.8\textwidth]{my-figure.png}
  \caption{My important result}
  \label{fig:myfig}
\end{figure}

The filename must match exactly.

References with BibTeX #

Upload a .bib file to Resources. In your document:

\bibliography{my-references}
\bibliographystyle{plain}

The compile workflow should handle BibTeX. If references don’t appear, consult your admin about enabling bibtex in the GitHub Actions workflow.

Troubleshooting #

• Error “! LaTeX Error: File … not found.” → Check the filename and that the file is uploaded to Resources
• Compilation takes >2 minutes → Large documents or missing packages; simplify or ask admin to install needed packages
• PDF blank or missing → The workflow may have failed; admin can check GitHub Actions logs

Need a Custom Document Class? #

If your institution provides a .cls file, upload it to Resources and \documentclass{institution}. Make sure the compile workflow includes that file in the build directory.
