Convert CELX to PDF

Understanding CELX and PDF file formats

CELX files are script files used by the Celestia space simulation software. These files contain Lua-based scripts that automate tasks, create tours, or add interactivity within Celestia. They are plain text files with a .celx extension and are not intended for direct viewing outside the Celestia environment.

PDF (Portable Document Format) is a widely used file format developed by Adobe for presenting documents in a manner independent of application software, hardware, or operating systems. PDFs are ideal for sharing, printing, and archiving documents.

Why convert CELX to PDF?

Converting a CELX file to PDF is useful when you want to share the script's content in a readable, non-editable format, or include it in documentation, tutorials, or reports.

How to convert CELX to PDF

Since CELX files are plain text, the conversion process involves opening the file in a text editor and exporting or printing it as a PDF. Here are the steps:

1. Open the CELX file in a text editor such as Notepad++ (Windows), Sublime Text (cross-platform), or TextEdit (Mac).
2. Review and format the script as needed for readability.
3. Go to File → Print or File → Export as PDF (if available).
4. If your editor does not support direct PDF export, select Print and choose Microsoft Print to PDF (Windows) or Save as PDF (Mac) as the printer.
5. Save the resulting PDF file to your desired location.
