Software to make working with TI-Basic files much easier on the PC by decompiling and recompiling the .8Xp files from the TI-83/TI-84 calculators. For more information about the 8Xp file format, see the site listed in the credits and the 8XP_Format.md file, which contains additional reverse-engineered information.

If you're looking for files to compile/decompile, you can find a number of TI programs at https://github.com/thenaterhood/ti-programs.

basically_ti_basic can be installed via pip with pip3 install basically-ti-basic, or it can be built. Once Python (3+) is installed on the target system, simply clone the repository and navigate to the cloned repository in the command line. Once there, run python setup.py install. You should be good to go.

basically_ti_basic provides a command line utility and a few libraries.

The command line utility should be available in your shell as the command basically-ti-basic. The utility allows for compilation and decompilation of TI-83+ .8Xp files. It provides the option to write the result to a file or print it to the console. Some usage examples:

Open the file FIBO.8Xp, decompile it, and save the result to FIBO.txt

$ basically-ti-basic -d -i FIBO.8Xp -o FIBO.txt

Open the file FIBO.txt, compile it, and save the result to FIBO.8Xp

$ basically-ti-basic -c -i FIBO.txt -o FIBO.8Xp

Open the file FIBO.8Xp, decompile it, and print the result to the console

$ basically-ti-basic -d -i FIBO.8Xp

basically_ti_basic can be used in a program as well.

import basically_ti_basic as btb

# Decompile 8Xp file
btb.decompile_file("input.8Xp", "tibasic.txt")

# Compile 8Xp file from TI-BASIC code
btb.compile_file("tibasic.txt", "output.8Xp")

Heads Up! The TI file creation (compilation) functionality is incomplete and may produce malformed files. Use it with caution and make sure to back up your calculator before loading any compiled files onto it.
