All notable changes to rtv-mod-impact-tracker are documented here. Dates are YYYY-MM-DD.
First public release. Eight Python scripts split into two pipelines — game-tracking (Steam-sourced) and dep-tracking (GitHub-sourced) — that together tell modders which of their mods will break when the host game patches or an upstream library updates.
Game tracking — for the host game you're modding:
snapshot.py— capture a decompiled-script snapshot of the current Steam build into a parallel*_historygit repo, one commit per game version. Auto-detects version + buildid fromproject.godotand the Steam ACF manifest; tags asgame-v<version>-build<buildid>.analyze_mods.py— diff two snapshot tags and classify each mod's impact (🔴 broken / 🟡 review / 🟢 safe). Renders an HTML report with inline syntax-highlighted diffs, side-by-side override-vs-vanilla comparison, and a per-mod summary table.changelog.py— render a Markdown changelog of game-side script changes between any two snapshot tags. Useful for release-notes posts and for understanding what shipped in a given patch.fetch_version.py— pull a historical Steam build via DepotDownloader using a manifest registry, decompile it, and commit it as a snapshot. Required only for backfilling old versions; day-to-day tracking usessnapshot.pyagainst the live install.
Dep tracking — for upstream mod loaders, config-menu frameworks, and content registries hosted on GitHub:
deps_fetch.py— sync local mirror clones of every upstream declared in[[deps]]ofmod_tracker.toml. Mirrors are gitignored; regenerable on demand.deps_diff.py— file-level + GDScript signature diff between two upstream tags. Highlights added / removed / renamed / signature-changed functions so the breaking-change surface is obvious at a glance.deps_audit.py— scan your own mods' call sites against a dep diff and flag anything that touches a changed API. Outputs a punch list of mod files + line numbers worth reviewing before bumping the upstream version requirement.deps_changelog.py— Markdown release notes summarising upstream changes between two tags. Drop-in for the dep's own release post or for internal "what's new" briefings.
Configuration & infrastructure:
- TOML-driven — single
mod_tracker.tomldeclares game paths, Steam app id, and the list of upstream[[deps]]. All scripts read from it, so adding a new dep is a one-block config change. - HTML reports with inline syntax highlighting (Pygments-via-stdlib fallback) — no external CSS hosting, runs offline.
- Stdlib-only Python (3.11+). No
pip installrequired for normal use; DepotDownloader is the only external binary, and onlyfetch_version.pyneeds it. - MIT licensed. Use it, fork it, ship it.
