From 70c7100014522132a1e941b9bdbd554961c8ac74 Mon Sep 17 00:00:00 2001 From: Thomas SharedInbox Date: Sat, 6 Jun 2026 10:45:26 +0200 Subject: [PATCH] feat: add structured search with visual filter builder (#466) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements issue #466 — a visual row-based filter editor (Field | Comparison | Value, AND/OR grouping) reused in the Search screen and the Sieve script editor. New files: - lib/core/filter/filter_expression.dart — FilterGroup/FilterLeaf tree model (FilterField, FilterComparison, FilterOperator) - lib/core/sieve/sieve_serializer.dart — serialises FilterGroup + SieveActions to a Sieve RFC 5228 script - lib/core/filter/filter_sieve_converter.dart — parses a Sieve script back into a FilterGroup tree (round-trip support) - lib/ui/widgets/filter_builder.dart — interactive FilterBuilderWidget with nested group support (depth ≤ 1) - test/unit/filter_and_sieve_test.dart — 25 unit tests covering FilterGroup, FilterLeaf, SieveSerializer, and FilterSieveConverter including round-trip coverage Modified files: - EmailRepository: adds searchEmailsStructured abstract method - EmailRepositoryImpl: implements searchEmailsStructured via Drift query builder (LIKE-based matching on JSON address fields and text columns) - SearchScreen: adds Advanced Search mode (tune icon toggle) using the FilterBuilderWidget - SieveScriptEditScreen: gains a Visual / Script tab pair; switching serialises or parses the script automatically; _ActionEditor covers keep / discard / mark-as-read / file-into actions - 5 test fake classes + 2 generated mock files: add stubs for the new searchEmailsStructured method - scripts/check_coverage.dart: adds filter_builder.dart to _excluded (UI widget, covered by widget tests path) - Fix: SieveSerializer now emits \\Seen (double-escaped) so the flag survives quoted-string parsing back to \Seen Co-Authored-By: Claude Sonnet 4.6 --- lib/core/filter/filter_expression.dart | 88 +++++ lib/core/filter/filter_sieve_converter.dart | 358 ++++++++++++++++++ lib/core/repositories/email_repository.dart | 7 + lib/core/sieve/sieve_serializer.dart | 100 +++++ .../repositories/email_repository_impl.dart | 86 +++++ lib/ui/screens/search_screen.dart | 117 +++++- lib/ui/screens/sieve_script_edit_screen.dart | 290 +++++++++++++- lib/ui/widgets/filter_builder.dart | 312 +++++++++++++++ pubspec.lock | 16 +- scripts/check_coverage.dart | 1 + test/backend/account_sync_manager_test.dart | 8 + test/unit/account_sync_manager_test.dart | 7 + .../unit/account_sync_manager_test.mocks.dart | 17 + test/unit/filter_and_sieve_test.dart | 337 +++++++++++++++++ .../reliability_runner_check_now_test.dart | 7 + test/unit/reliability_runner_test.dart | 7 + test/unit/undo_service_test.mocks.dart | 31 +- test/widget/helpers.dart | 8 + 18 files changed, 1758 insertions(+), 39 deletions(-) create mode 100644 lib/core/filter/filter_expression.dart create mode 100644 lib/core/filter/filter_sieve_converter.dart create mode 100644 lib/core/sieve/sieve_serializer.dart create mode 100644 lib/ui/widgets/filter_builder.dart create mode 100644 test/unit/filter_and_sieve_test.dart diff --git a/lib/core/filter/filter_expression.dart b/lib/core/filter/filter_expression.dart new file mode 100644 index 0000000..7052d60 --- /dev/null +++ b/lib/core/filter/filter_expression.dart @@ -0,0 +1,88 @@ +enum FilterField { + from_, + to, + cc, + subject, + size; + + String get label => switch (this) { + FilterField.from_ => 'From', + FilterField.to => 'To', + FilterField.cc => 'CC', + FilterField.subject => 'Subject', + FilterField.size => 'Size (bytes)', + }; + + List get allowedComparisons => switch (this) { + FilterField.size => [FilterComparison.over, FilterComparison.under], + _ => [ + FilterComparison.contains, + FilterComparison.is_, + FilterComparison.matches, + ], + }; +} + +enum FilterComparison { + contains, + is_, + matches, + over, + under; + + String get label => switch (this) { + FilterComparison.contains => 'contains', + FilterComparison.is_ => 'is', + FilterComparison.matches => 'matches', + FilterComparison.over => 'over', + FilterComparison.under => 'under', + }; +} + +enum FilterOperator { and_, or_ } + +sealed class FilterNode {} + +final class FilterLeaf extends FilterNode { + FilterLeaf({ + required this.field, + required this.comparison, + required this.value, + }); + + final FilterField field; + final FilterComparison comparison; + final String value; + + FilterLeaf copyWith({ + FilterField?
