Luna 2.0

Luna is a portable command-line converter of Lua programs to TNS TI-Nspire documents, compatible with OS 3.0.2 and later.

It can also be used to convert any TI-Nspire problems in XML format to TNS documents.

Usage

• Lua program conversion: luna INFILE.lua OUTFILE.tns
• Problem conversion: luna Problem1.xml OUTFILE.tns
• Multiple files: luna Document.xml Problem1.xml [Problem2.xml...] OUTFILE.tns

If the input is -, it reads the file from the standard input.
Make sure to encode your Lua or Problem file in UTF-8 if it contains special characters. You can also pack arbitrary files like images into the TNS.
