texosquery – Cross-platform Java application to query OS information

This package provides a cross-platform Java application to query OS information designed for use in TeX’s shell escape mechanism.

The application can query the following:

• locale and codeset
• current working directory
• user home directory
• temporary directory
• OS name, arch and version
• Current date and time in PDF format (for TeX formats that don’t provide \pdfcreationdate)
• Date-time stamp of a file in PDF format (for TeX formats that don't provide \pdffilemoddate)
• Size of a file in bytes (for TeX formats that don’t provide \pdffilesize)
• Contents of a directory (captured as a list)
• Directory contents filtered by regular expression (captured as a list)
• URI of a file
• Canonical path of a file

All paths use a forward slash as directory divider so results can be used, for example, in commands like \includegraphics.

There are files provided for easy access in TeX documents:

• texosquery.tex: generic TeX code
• texosquery.sty: LaTeX package

This provides commands to run texosquery using TeX’s shell escape mechanism and capture the result in a control sequence. The category code of most of TeX’s default special characters (and some other potentially problematic characters) is temporarily changed to 12 while reading the result.
