WTF - SCI Script to Python3 - experiment to modernize the SCI source code...
# Hello, before anyone freaks out this is just an experiment...to see how far the rabbit hole can go.
# Original .sc file for ref: https://github.com/EricOakford/SCI-Decompilation-Archive/blob/master/lsl1/src/rmSidewalk.sc
# SCI script is really interesting to me, but largely outdated
# Based on a combination of Small-Talk and Lisp, with Prefix notation for expressions...it can get unwieldy
# to read at least for me. Boat-load of paranthesis and expressions that don't read like normal infix notation.
# But,

deckarep / align_asm.py
Created November 10, 2023 02:02
A quick and dirty work-in-progress script that can help align blocks of assembly language since doing it manually is tedious and boring and hurts my eyes.
#!/usr/bin/env python3
import sys
class NasmAligner:
def __init__(self, start_address=0):
self.alignments = {'DB': 1, 'DW': 2, 'DD': 4, 'DQ': 8}
self.output_lines = []
self.current_address = start_address

Created November 9, 2023 04:57
A stupid simple Python utility to quickly print out the alignment of an integer provided on the command line.
import sys
def check_alignment(val):
alignments = {
'2-byte': val & 0x1 == 0,
'4-byte': val & 0x3 == 0,
'8-byte': val & 0x7 == 0,
'16-byte': val & 0xF == 0,
'32-byte': val & 0x1F == 0,
'64-byte': val & 0x3F == 0,
