Matt's code thicket

A sometimes-tended garden of things a hewer of maps has made and copied that can occasionally be turned to useful work.

Quick start

Most Python scripts run with uv and need no prior setup:

uv run tools/gitignore_to_fossil.py .gitignore
uv run gis/get-fgdb-stats.py path/to/data.gdb
uv run video/extract_poster_frames.py holiday.mp4 --contact-sheet

Scripts that require ArcGIS Pro, Windows registry access, or other managed environments note their prerequisites in their own headers.

Folder map

Folder	Contents
gis/	GIS, ArcGIS, GDAL, QGIS, DEM and geospatial conversion tools
arcplus/	ArcGIS Desktop helper modules and toolbox scripts (Python 2 / arcpy)
tools/	Ready-to-run general utilities; see tools/Readme.md
video/	Video-processing helpers (poster-frame extraction, etc.)
metril/	OneNote → Trilium migration helpers
register-python/	Windows Python registry inspection and registration helpers
other/	Assorted Windows, shell, PDF, media, and admin scripts
Lib/	Reusable Python helpers (e.g. pyuac.py for UAC elevation)
scrapbook/	Experiments and reference snippets
llm/	LLM / AI workflow helpers

Requirements

• Python 3.10+ for modern scripts; older scripts in arcplus/ and register-python/ were written for Python 2 / ArcGIS Desktop 10.x
• uv — handles per-script dependencies declared via PEP 723 inline metadata (# /// script … /// blocks)
• ArcGIS Pro (optional) — needed by arcplus/report-versions.py and other arcplus/ scripts
• fiona, typer, rich, openpyxl — pulled automatically by uv run for gis/get-fgdb-stats.py

Code quality

ruff is configured in ruff.toml. Run it on any script before committing:

uv tool run ruff check path/to/script.py
uv tool run ruff format path/to/script.py
