From 7347b3ebf2954932e298b8cf78e3a534715d5dbb Mon Sep 17 00:00:00 2001 From: justincasher Date: Sat, 9 May 2026 12:23:39 -0700 Subject: [PATCH 1/2] Render candidates README from Reservoir manifest Adds aggregator.render with render_table(manifest) and update_readme() that replace the content between BEGIN/END AUTOGENERATED markers. Restructures the aggregator CLI as a click group with two subcommands: fetch (existing behavior) and render (new). Default paths point at aggregator/candidates/raw_data/manifest.json and the candidates README. Renders all 617 packages currently in Reservoir into the README sorted by stars descending with ties broken alphabetically. The packages/ subfolder and its .gitkeep are removed; inclusion decisions will be tracked in a separate decisions.jsonl when we start making them, not in per-package metadata files. --- aggregator/candidates/README.md | 638 +++++++++++++++++++++++- aggregator/candidates/packages/.gitkeep | 0 python/lean_pool/aggregator/__main__.py | 51 +- python/lean_pool/aggregator/render.py | 141 ++++++ python/tests/aggregator/test_render.py | 184 +++++++ 5 files changed, 997 insertions(+), 17 deletions(-) delete mode 100644 aggregator/candidates/packages/.gitkeep create mode 100644 python/lean_pool/aggregator/render.py create mode 100644 python/tests/aggregator/test_render.py diff --git a/aggregator/candidates/README.md b/aggregator/candidates/README.md index 37ffc4fc85..fbf45e56aa 100644 --- a/aggregator/candidates/README.md +++ b/aggregator/candidates/README.md @@ -5,19 +5,635 @@ Tracking which Lean packages we are considering for inclusion in ## Layout -- `packages/` — one file per candidate package, holding the curated - metadata and review status.
