From 2548665895ea427fb0116feff6b6c6cb878cc6be Mon Sep 17 00:00:00 2001 From: Kevin Kenyon Date: Sun, 28 Dec 2025 17:09:54 -0600 Subject: [PATCH 1/6] Refactor tinygrid/ercot.py into modular subpackage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This refactoring breaks the monolithic ercot.py (3680 lines) into a well-organized subpackage with clear separation of concerns: ## New Module Structure - `tinygrid/ercot/__init__.py` - Main ERCOT class combining mixins - `tinygrid/ercot/client.py` - ERCOTBase with auth, retry, pagination - `tinygrid/ercot/endpoints.py` - Low-level pyercot wrappers (~100 methods) - `tinygrid/ercot/api.py` - High-level unified API (get_spp, get_lmp, etc.) - `tinygrid/ercot/archive.py` - Historical archive access (moved from historical/) - `tinygrid/ercot/dashboard.py` - Public dashboard methods (no auth required) - `tinygrid/ercot/documents.py` - MIS document fetching for yearly data - `tinygrid/ercot/transforms.py` - Data filtering and transformation utilities ## New Features - Dashboard methods: get_status(), get_fuel_mix(), get_energy_storage_resources() - MIS document fetching: _get_documents(), read_doc(), REPORT_TYPE_IDS - Historical yearly methods: get_rtm_spp_historical(year), get_dam_spp_historical(year) - Renamed decorator: @support_date_range → @with_date_range (backward-compatible) ## Architecture Improvements - Mixin-based design for composable functionality - Standalone transform functions separate data manipulation from API logic - Cleaner import structure with proper re-exports for backward compatibility All 505 tests pass. --- tests/conftest.py | 18 +- tests/test_ercot.py | 22 +- tests/test_ercot_dataframe.py | 24 +- tests/test_ercot_helpers.py | 142 +- tests/test_ercot_http_historical.py | 2 +- tests/test_ercot_retry.py | 24 +- tests/test_ercot_unified.py | 24 +- tests/test_historical_archive.py | 2 +- tinygrid/__init__.py | 6 +- tinygrid/ercot/__init__.py | 231 +++ tinygrid/ercot/api.py | 622 ++++++ .../{historical/ercot.py => ercot/archive.py} | 4 +- tinygrid/ercot/client.py | 665 +++++++ tinygrid/ercot/dashboard.py | 272 +++ tinygrid/ercot/documents.py | 335 ++++ tinygrid/{ercot.py => ercot/endpoints.py} | 1766 +---------------- tinygrid/ercot/transforms.py | 289 +++ tinygrid/historical/__init__.py | 10 +- tinygrid/utils/__init__.py | 3 +- tinygrid/utils/decorators.py | 8 +- 20 files changed, 2585 insertions(+), 1884 deletions(-) create mode 100644 tinygrid/ercot/__init__.py create mode 100644 tinygrid/ercot/api.py rename tinygrid/{historical/ercot.py => ercot/archive.py} (99%) create mode 100644 tinygrid/ercot/client.py create mode 100644 tinygrid/ercot/dashboard.py create mode 100644 tinygrid/ercot/documents.py rename tinygrid/{ercot.py => ercot/endpoints.py} (50%) create mode 100644 tinygrid/ercot/transforms.py diff --git a/tests/conftest.py b/tests/conftest.py index 9c01bfd..033a4f8 100644 --- a/tests/conftest.py +++ b/tests/conftest.py @@ -86,7 +86,12 @@ def sample_records(): @pytest.fixture def sample_paginated_response(sample_fields, sample_records): - """Create a sample paginated API response.""" + """Create a sample paginated API response. + + Note: This is for mock patching pyercot endpoints directly, which + returns data as pyercot transforms it.
