From 8d7bd57526486cab9e3daba9934042c405d7946b Mon Sep 17 00:00:00 2001 From: Mitchell Balan Date: Thu, 31 Oct 2019 11:07:36 -0400 Subject: [PATCH] [clang-format] Fix SpacesInSquareBrackets for Lambdas with Initial "&ref" Parameter Summary: This fixes an edge case in the `SpacesInSquareBrackets` option where an initial `&ref` lambda parameter is not padded with an initial space. `int foo = [&bar ]() {}` is fixed to give `int foo = [ &bar ]() {}` Reviewers: MyDeveloperDay, klimek, sammccall Reviewed by: MyDeveloperDay Subscribers: cfe-commits Tags: #clang, #clang-format Differential Revision: https://reviews.llvm.org/D69649 --- clang/lib/Format/TokenAnnotator.cpp | 2 +- clang/unittests/Format/FormatTest.cpp | 4 ++++ 2 files changed, 5 insertions(+), 1 deletion(-) diff --git a/clang/lib/Format/TokenAnnotator.cpp b/clang/lib/Format/TokenAnnotator.cpp index 1ed35597d075d..98b87c0f5a25e 100644 --- a/clang/lib/Format/TokenAnnotator.cpp +++ b/clang/lib/Format/TokenAnnotator.cpp @@ -2567,7 +2567,7 @@ bool TokenAnnotator::spaceRequiredBetween(const AnnotatedLine &Line, return Left.Tok.isLiteral() || (Left.is(tok::identifier) && Left.Previous && Left.Previous->is(tok::kw_case)); if (Left.is(tok::l_square) && Right.is(tok::amp)) - return false; + return Style.SpacesInSquareBrackets; if (Right.is(TT_PointerOrReference)) { if (Left.is(tok::r_paren) && Line.MightBeFunctionDecl) { if (!Left.MatchingParen) diff --git a/clang/unittests/Format/FormatTest.cpp b/clang/unittests/Format/FormatTest.cpp index e0ebef1f7cede..ea03ee1c3cc9e 100644 --- a/clang/unittests/Format/FormatTest.cpp +++ b/clang/unittests/Format/FormatTest.cpp @@ -10572,6 +10572,10 @@ TEST_F(FormatTest, ConfigurableSpacesInSquareBrackets) { // Lambdas. verifyFormat("int c = []() -> int { return 2; }();\n", Spaces); verifyFormat("return [ i, args... ] {};", Spaces); + verifyFormat("int foo = [ &bar ]() {};", Spaces); + verifyFormat("int foo = [ = ]() {};", Spaces); + verifyFormat("int foo = [ =, &bar ]() {};", Spaces); + verifyFormat("int foo = [ &bar, = ]() {};", Spaces); } TEST_F(FormatTest, ConfigurableSpaceBeforeAssignmentOperators) {
