From d54e7aa9e252a9d895c1250a0512e5323632efb8 Mon Sep 17 00:00:00 2001 From: Ben Hamilton Date: Tue, 27 Mar 2018 15:01:17 +0000 Subject: [PATCH] [clang-format] Do not insert space before closing brace in ObjC dict literal Summary: Previously, `clang-format` would sometimes insert a space before the closing brace in an Objective-C dictionary literal. Unlike array literals (which obey `Style.SpacesInContainerLiterals` to add a space after `[` and before `]`), Objective-C dictionary literals currently are not meant to insert a space after `{` and before `}`, regardless of `Style.SpacesInContainerLiterals`. However, some constructs like `@{foo : @(bar)}` caused `clang-format` to insert a space between `)` and `}`. This fixes the issue and adds tests. (I understand the behavior is not consistent between array literals and dictionary literals, but that's existing behavior that's a much larger change.) Test Plan: New tests added.
