From 441b93a75b9941d395edfe4b65ed0af2da9e0021 Mon Sep 17 00:00:00 2001 From: "Danilo M." Date: Fri, 14 Aug 2026 12:42:38 +0200 Subject: feat(search): build notmuch terms for the right-click actions One place for the query grammar behind every search surface, with no widget involved so it is tested without a painter or a web engine. extend() parenthesises both sides. The query bar may hold a hand-written disjunction, and 'a or b AND c' binds as 'a or (b AND c)', which widens a search meant to narrow it and reports nothing. --- tests/CMakeLists.txt | 1 + tests/test_searchterm.cpp | 146 ++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 147 insertions(+) create mode 100644 tests/test_searchterm.cpp (limited to 'tests') diff --git a/tests/CMakeLists.txt b/tests/CMakeLists.txt index e5142b6..5b0b85b 100644 --- a/tests/CMakeLists.txt +++ b/tests/CMakeLists.txt @@ -54,3 +54,4 @@ add_qtmaildir_test(querycompleter) add_qtmaildir_test(tagdialog) add_qtmaildir_test(tagrules) add_qtmaildir_test(rulequery) +add_qtmaildir_test(searchterm) diff --git a/tests/test_searchterm.cpp b/tests/test_searchterm.cpp new file mode 100644 index 0000000..e0bdb60 --- /dev/null +++ b/tests/test_searchterm.cpp @@ -0,0 +1,146 @@ +/* + * qtmaildir - a Qt6 mail client for notmuch-indexed Maildirs + * Copyright (C) 2026 Danilo M. + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
