unicat-esolang

Python 3 Port of Unicat Esoteric Language created by gemdude46. See this Sample Programs in Every Language article for a description of the language.

Prerequisites

Python 3.8 or later

Installing or Updating

This package has no dependencies, so it is safe to do this:

pip install --user -U esocat-lang

However, if you want to install this is in virtualenv, you can do this once you have activated the virtualenv:

pip install -U esocat-lang

Usage

Use this to run your Unicat program:

unicat [-d/--debug] FILENAME

where:

• -d or --debug enables debugging
• FILENAME is the path to the Unicat program

Debugging

When unicat is run with -d or --debug, the python debugger is entered before each instruction. The first time, a welcome screen is displayed:

Welcome to the Unicat debugger

Here are the commands:

- show_ins()           - Show instructions
- show_mem()           - Show all memory
- show_mem(start)      - Show memory address `<start>`
- show_mem(start, end) - Show memory address `<start>` to `<end>`
- c                    - Execute next instruction

Everything else is just a pdb command.
See https://docs.python.org/3/library/pdb.html for details.

When the debugger is entered, the current instruction is displayed. For example:

Current instruction:
Address 0 (0o0): asgnlit 0 (0o0), 72 (0o110 = 'H')
> ...execute_instructions()
-> if it[0] == "diepgrm":

Examples

Example programs can be found here. These programs are also used for unit testing the Unicat language implementation.
