TI-BASIC to Python 3 Transpiler

ti842py

---

ti842py is a TI-BASIC to Python 3 transpiler. A transpiler is a piece of software that can convert code from one language to another. This program should be able to convert a lot of programs, but if you find something that it can't convert yet, start an issue. This transpiler also has the ability to automatically decompile any 8Xp file that you supply as the input file, with the help of my other project basically-ti-basic.

Installation

---

ti842py can be installed via PyPI or by cloning the repository. To install it with PyPI, just run pip3 install ti842py in a terminal. To install it locally, you can clone the repository and run python setup.py install --user.

Usage

---

ti842py can be used in 3 different ways. The first way is just running it from the command line. For example, if you wanted to convert the program in tiprogram.txt to tiprogram.py, you can this command: ti842py -i tiprogram.txt -o tiprogram.py. If no value is specified for -o, the converted program will be written to stdout. The -n flag can be added to force the transpiler to not decompile the input file, and the -d flag can be added to force the transpiler to attempt and decompile the input file

usage: ti842py [-h] [-o O] -i I [-n] [-d]

optional arguments:
  -h, --help            show this help message and exit
  -o O                  Optional output file to write to. Defaults to standard out.
  -i I                  Input file.
  -n, --force-normal    Forces the program to not attempt and decompile the input file. Useful for false positives
  -d, --force-decompile
                        Forces the program to attempt to decompile the input file

ti842py can also be imported and used in a program. Here is an example program to convert tiprogram.txt to tiprogram.py:

from ti842py import transpile

transpile("tiprogram.txt", "tiprogram.py")

Again, if the second argument is not supplied, the program will be written to stdout. The transpile command can be supplied with 2 optional arguments, decompileFile and forceDecompile. decompileFile defaults to True, and forceDecompile defaults to False

The last way that ti842py can be ran is by running the main python file. After cloning the repository, cd into the repository and run python ti842py/main.py -i inputfile.txt. You can supply any arguments that you would supply with the ti842py command.
