Closes #103

Context

Node and library searches previously relied on strict substring containment (contains). Typing common acronyms or partial abbreviations (like dblur for Directional Blur, dirwarp for Directional Warp, or t2d for Transformation 2D) produced no results.

Changes

  • Fuzzy subsequence scoring (crates/ui-egui/src/fuzzy.rs):
    • Implements case-insensitive subsequence matching with standards-compliant Unicode NFC normalization via unicode-normalization (Unicode Standard Annex Allow users to press Tab to open the node search menu #15).
    • Scores contiguous character matches (+8), word boundaries (+6), exact prefix (+50), word-prefix (+40), and exact matches (+100).
    • Multi-word queries evaluate tokens via iterators without intermediate vector allocations.
    • Length penalty (hay.len() / 16) ensures concise matches rank before sprawling names.
  • Node Search Popup (crates/ui-egui/src/graph/search.rs):
    • Evaluates candidate nodes against label, id, and category.
    • Ranks descending by score with alphabetical tie-breaks. Preserves catalog order when query is empty.
  • Library Panels (library.rs and function/library.rs):
    • Wires fuzzy scoring into node library filtering and function library filtering.

Tests

  • Unit tests in fuzzy::tests (including multi-accent canonical composition and L/dot distinction) and graph::search::tests.
  • Kittests in tests/search.rs (query::fuzzy_subsequence_query_selects_and_inserts_matching_node).
  • All 235 unit tests and integration test suites pass (cargo test -p materialcraft-ui-egui).
  • cargo fmt --all -- --check passes.
  • cargo xtask layers reports no layering violations.

Summary by CodeRabbit

  • New Features
    • Search across function, operation, and node catalogs now supports fuzzy, partial, and acronym-style matches, including matches across names, identifiers, and categories.
    • Results are ranked by relevance, with labels used to break ties. Surrounding whitespace is ignored, and blank searches retain each catalog’s original order.
  • Tests
    • Added coverage for fuzzy matching, result ranking, cross-field searches, and selecting a matching node from search.

Walkthrough

Function and node searches trim queries and use shared fuzzy scoring to match and rank results. Empty queries retain eligible entries in their source order. Tests cover scoring, result ordering, and fuzzy node selection and insertion.

Changes: Fuzzy Search

Layer / File(s) Summary
Fuzzy scoring
crates/ui-egui/src/fuzzy.rs, crates/ui-egui/src/lib.rs
A public fuzzy_score function scores exact, prefix, word-prefix, substring, and subsequence matches. It also handles multiword queries and Unicode normalization and folding. Unit tests cover query handling and scoring behavior.
Node search ranking
crates/ui-egui/src/graph/search.rs
Node search uses fuzzy scores from labels, IDs, and categories. It supports multiword matches across fields and sorts results by score, then label. Tests cover matching and ordering.
Function and catalog search ranking
crates/ui-egui/src/function/library.rs, crates/ui-egui/src/library.rs, crates/ui-egui/tests/it/search/query.rs
Function and catalog searches use fuzzy scores and sort matches by score, with labels as tie-breakers. A UI test verifies that dblur selects and inserts the “Directional blur” node.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: Low · up to 47222

Fuzzy search is mergeable with bounded follow-up for uncommon Unicode labels that can disappear from filtered function results. The previous multibyte scoring-test and unsupported-mark preservation concerns are fixed.

Explanation

Open issue #103 requests fuzzy search in search fields. The reviewed changes add case-insensitive subsequence scoring and use it in node search, node library filtering, and function library filtering. The summaries also report unit and UI tests for fuzzy matching, ranking, and node insertion. The Unicode folding additions support the same search behavior.

Full details: Out of Scope Changes check

Explanation

The reported changes are limited to fuzzy scoring, its use in the requested search fields, and related tests. The Unicode normalization and folding changes support fuzzy matching. The public fuzzy module exposes the implementation but does not introduce a separate feature.

22-23: Minor · Functional Correctness · Poor tradeoff

Use Unicode case folding for search comparisons.

A search for Σ can omit an SBS function labeled ΟΣ if its ASCII path does not match. Lowercasing produces ος for the label and σ for the query. The previous filter matched this label.

Apply Unicode case folding to both inputs before matching. Add assert!(fuzzy_score("ΟΣ", "Σ").is_some()); to cover this case.

Preserve unsupported combining marks during normalization.

A decomposed a\u{030A} becomes plain a, so it can match unrelated entries and fails to match precomposed å. Use Unicode normalization that preserves canonical equivalence, and add tests for marks outside the composition table.

@kk376 The commit preserves unsupported combining marks and adds the ring and caron tests. However, canonical equivalence is still incomplete.

For example, fuzzy_score("ġ", "g\u{0307}") returns None because that composition is not in the table. Please use Unicode normalization and add a regression test for a composition outside the table.

I inspected the code but did not run the tests.

composing the macron, including the dot above. Ensure SBS labels containing
`İ\u{0304}` remain searchable by the corresponding lowercase-expanded query.
- Around line 83-91: Update the normalization logic around push_case_folded so
ligatures are expanded before accents are composed, making ffi followed by a
combining acute equivalent to the ligature ffi followed by the same accent in
either input order. Add coverage for both query/label orderings.
- Around line 83-85: Normalize both the SBS function label and query before
fuzzy matching so canonically equivalent strings with reordered combining marks
match; use the project’s existing Unicode normalization support rather than
assuming a new API. Update the matching flow around push_case_folded and add a
regression test that verifies reordered combining marks still return the
function in library results.

Normalize combining marks before fuzzy matching.

If an SBS function label and the query use canonically equivalent combining-mark orders, the function can disappear from the library results. Normalize both strings before matching, and add a regression test for reordered marks.

Review comment at @crates/ui-egui/src/fuzzy.rs around lines 83 - 85:
Normalize both the SBS function label and query before fuzzy matching so
canonically equivalent strings with reordered combining marks match; use the
project’s existing Unicode normalization support rather than assuming a new API.
Update the matching flow around push_case_folded and add a regression test that
verifies reordered combining marks still return the function in library results.

Expand ligatures before composing accents.

A query of ffi\u{0301} does not match a label containing ffi\u{0301}, or vice versa. The two forms fold differently, so the function library can exclude the matching entry. Expand ligatures before composing accents and test both input orders.

Preserve the lowercase expansion before composing diacritics.

If an SBS function label contains İ\u{0304}, a search for i\u{0307}\u{0304} can exclude it. Composition drops the dot from İ, so the label folds to ī. Preserve the full lowercase expansion when composing diacritics.

Review comment at @crates/ui-egui/src/fuzzy.rs at line 153:
Update the diacritic-composition logic around the `('i', '\u{0304}')` mapping so
it preserves the full lowercase expansion of `İ` when composing the macron,
including the dot above. Ensure SBS labels containing `İ\u{0304}` remain
searchable by the corresponding lowercase-expanded query.

Compose j with a combining caron.

When an SBS function label contains ǰ and the query uses j\u{030c}, or vice versa, the label does not match. If the function path also does not match, the library omits the entry.

Reviewed current head 4f3f5dd, all changed source and the node-popup/library callers. The fuzzy matching wiring and empty-query ordering are clear, but please replace or correct the ad-hoc Unicode normalization before claiming canonical equivalence.

compose_diacritic maps l + U+0307 (COMBINING DOT ABOVE) to U+0140 (ŀ, L WITH MIDDLE DOT), which is a different character, not its NFC form. Multi-accent canonical equivalents also fail: ắ stays ắ, while a + U+0306 + U+0301 becomes ă followed by an uncomposed acute because there is no (ă, acute) mapping. Thus canonically equivalent names can fail to match, while distinct text can be conflated. The two-class combining-order approximation is not Unicode canonical ordering either. Prefer a standards-backed normalization implementation within the allowed licenses (or remove the normalization claim/partial transforms and state the supported behavior explicitly). Add regression pairs covering multi-accent composition and the L/dot distinction.

The PR description also calls this zero-allocation, but case_fold allocates a vector and String and the scorer allocates token vectors repeatedly per candidate; please correct that claim. I did not run local tests or performance measurements. The current head exposes only a skipped CodeRabbit check, so applicable Rust/UI validation remains unverified; rendered UI snapshots also remain uninspected.

Good catch @FredApps, thanks for the review.

Addressed in commit c937752:

  • Replaced the ad-hoc diacritic table with standards-compliant NFC normalization via unicode-normalization (version 0.1, matching other craftapp crates).
  • Added regression tests covering multi-accent canonical composition (ắ vs a + \u{0306} + \u{0301}) and the L/dot distinction (l + \u{0307} vs ŀ).
  • Cleaned up token allocation in multi-word scoring to evaluate via iterators without vector collection, and corrected the PR description claims.
  • All 235 materialcraft-ui-egui tests, clippy, and formatting pass cleanly.
