From 7883ae0eba83daa1fa74ab50dbcaae9e3fd03ec6 Mon Sep 17 00:00:00 2001 From: Russell Ballestrini Date: Mon, 5 Jan 2026 17:30:58 -0500 Subject: [PATCH] Refactor: Extract neopig package from neopig.py Phase 1 of module restructuring as outlined in docs/REFACTOR.md: New neopig/ package modules: - live.py: Live media queue (get_live_queue, emit_live_media) - state.py: AppendOnlyStateLog, state file helpers - html_utils.py: trim_html_wrapper, extract_meta_from_html - logging.py: TqdmLoggingHandler, job logging functions - backfill/: markdown and screenshot backfill operations Package features: - Lazy import of NeoPig/main from neopig.py via __getattr__ - Full backwards compatibility with existing imports - 42 new unit tests for extracted modules Total: 458 tests passing --- neopig/__init__.py | 65 ++++++ neopig/backfill/__init__.py | 13 ++ neopig/backfill/markdown.py | 300 +++++++++++++++++++++++++++ neopig/backfill/screenshots.py | 273 ++++++++++++++++++++++++ neopig/html_utils.py | 83 ++++++++ neopig/live.py | 29 +++ neopig/logging.py | 75 +++++++ neopig/state.py | 182 ++++++++++++++++ tests/unit/test_neopig.py | 9 +- tests/unit/test_neopig_html_utils.py | 120 +++++++++++ tests/unit/test_neopig_live.py | 71 +++++++ tests/unit/test_neopig_logging.py | 131 ++++++++++++ tests/unit/test_neopig_state.py | 184 ++++++++++++++++ 13 files changed, 1531 insertions(+), 4 deletions(-) create mode 100644 neopig/__init__.py create mode 100644 neopig/backfill/__init__.py create mode 100644 neopig/backfill/markdown.py create mode 100644 neopig/backfill/screenshots.py create mode 100644 neopig/html_utils.py create mode 100644 neopig/live.py create mode 100644 neopig/logging.py create mode 100644 neopig/state.py create mode 100644 tests/unit/test_neopig_html_utils.py create mode 100644 tests/unit/test_neopig_live.py create mode 100644 tests/unit/test_neopig_logging.py create mode 100644 tests/unit/test_neopig_state.py diff --git a/neopig/__init__.py b/neopig/__init__.py new file mode 100644 index 0000000..82ad5ab --- /dev/null +++ b/neopig/__init__.py @@ -0,0 +1,65 @@ +""" +neopig -
