📝 Walkthrough

Walkthrough

Adds configurable Git recency ranking. Recent branch commits add per-file score bonuses. The change updates indexing, scoring, integrations, UI output, tests, snapshots, and documentation.

Changes

Git recency ranking

Layer / File(s) Summary
Recency computation and data contracts
crates/fff-core/src/git_recency.rs, crates/fff-core/src/types.rs, crates/fff-core/src/git.rs, crates/fff-core/src/lib.rs
Computes bounded branch-history scores and adds recency fields to core types.
Picker collection and refresh integration
crates/fff-core/src/file_picker.rs, crates/fff-core/src/shared.rs
Computes recency during collection and refresh, then applies scores to indexed files.
Scoring and integration wiring
crates/fff-core/src/score.rs, crates/fff-nvim/..., lua/fff/..., crates/fff-c/..., crates/fff-python/..., crates/fff-mcp/...
Adds recency to ranking, parses configuration, preserves settings during reindexing, and exposes score details.
Validation and documentation
crates/fff-core/tests/git_recency_integration.rs, tests/git_recency_spec.lua, tests/screenshots/..., README.md, doc/fff.nvim.txt, lua/fff/conf.lua
Tests scoring, limits, refreshes, branch changes, and disabling. Updates documentation and snapshots.

Normalize base_path before deriving subdir.

On Unix, FilePicker::new preserves .., while git_recency::compute returns repository-relative paths. For /repo/sub/.., strip_prefix produces sub/..; the resulting sub/../ prefix matches no Git path, so all recency scores stay zero. Normalize base_path lexically and add a .. regression test.

Set Sort::TIME before seeding the revwalk.

Sort::NONE is arbitrary in git2 0.21.0. The budget can therefore stop before newer commits and produce incorrect recency scores. Add revwalk.set_sorting(git2::Sort::TIME).ok()?; before revwalk.push(head).

In `@crates/fff-core/src/git_recency.rs` at line 25, Update the revwalk setup in
the per-file recency computation to call set_sorting with git2::Sort::TIME
before revwalk.push(head), preserving the existing error propagation behavior.
