From 76ddb865302159cb7da3c9ed59429527e4ae7a47 Mon Sep 17 00:00:00 2001 From: Steffen Heil | secforge Date: Mon, 27 Oct 2025 08:02:50 +0100 Subject: [PATCH] feat: add nextLineExceptAfterBrace control flow position option MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add new control flow positioning option that keeps keywords on same line after closing braces, but moves to next line when braces are removed or when trailing comments are present. This provides better formatting for control flow statements like if-else, try-catch-finally, and do-while. Behavior: - `if (x) { f(); } else { g(); }` → keeps else on same line - `if (x) f(); else g();` → moves else to next line (no braces) - `if (x) { f(); } // comment\nelse { g(); }` → moves else to next line (trailing comment) - Empty blocks stay compact: `try {} catch {}` stays on same line - Works with all control flow: if-else, try-catch-finally, do-while Configuration: - `ifStatement.nextControlFlowPosition: "nextLineExceptAfterBrace"` - `tryStatement.nextControlFlowPosition: "nextLineExceptAfterBrace"` - `doWhileStatement.nextControlFlowPosition: "nextLineExceptAfterBrace"` Fixes: - Empty single-line blocks now stay compact instead of expanding - Fixed SameLine mode bug where empty blocks incorrectly forced newlines Tests: - Added 69 new test cases covering all scenarios - Added separate ASI test files following existing patterns - All 654 tests passing 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- deployment/schema.json | 3 + src/configuration/types.rs | 10 +- src/generation/generate.rs | 204 ++++++++- ...lFlowPosition_NextLineExceptAfterBrace.txt | 141 ++++++ ...wPosition_NextLineExceptAfterBrace_Asi.txt | 49 +++ ...ontrolFlowPosition_Maintain_PreferNone.txt | 30 ++ ...lFlowPosition_NextLineExceptAfterBrace.txt | 349 +++++++++++++++ ...wPosition_NextLineExceptAfterBrace_Asi.txt | 51 +++ .../tryStatement/TryStatement_All.txt | 12 +- ...ement_NextControlFlowPosition_Maintain.txt | 48 +++ ...ement_NextControlFlowPosition_NextLine.txt | 32 ++ ...lFlowPosition_NextLineExceptAfterBrace.txt | 407 ++++++++++++++++++ ...wPosition_NextLineExceptAfterBrace_Asi.txt | 68 +++ ...ement_NextControlFlowPosition_SameLine.txt | 46 ++ 14 files changed, 1435 insertions(+), 15 deletions(-) create mode 100644 tests/specs/statements/doWhileStatement/DoWhileStatement_NextControlFlowPosition_NextLineExceptAfterBrace.txt create mode 100644 tests/specs/statements/doWhileStatement/DoWhileStatement_NextControlFlowPosition_NextLineExceptAfterBrace_Asi.txt create mode 100644 tests/specs/statements/ifStatement/IfStatement_NextControlFlowPosition_Maintain_PreferNone.txt create mode 100644 tests/specs/statements/ifStatement/IfStatement_NextControlFlowPosition_NextLineExceptAfterBrace.txt create mode 100644 tests/specs/statements/ifStatement/IfStatement_NextControlFlowPosition_NextLineExceptAfterBrace_Asi.txt create mode 100644 tests/specs/statements/tryStatement/TryStatement_NextControlFlowPosition_NextLineExceptAfterBrace.txt create mode 100644 tests/specs/statements/tryStatement/TryStatement_NextControlFlowPosition_NextLineExceptAfterBrace_Asi.txt diff --git a/deployment/schema.json b/deployment/schema.json index 50c4f059..a2b32661 100644 --- a/deployment/schema.json +++ b/deployment/schema.json @@ -199,6 +199,9 @@ }, { "const": "nextLine", "description": "Forces the next control flow to be on the next line." + }, { + "const": "nextLineExceptAfterBrace", + "description": "Forces the next control flow to be on the next line, except when preceded by a brace." }] }, "trailingCommas": { diff --git a/src/configuration/types.rs b/src/configuration/types.rs index 1e67d7b7..970376b2 100644 --- a/src/configuration/types.rs +++ b/src/configuration/types.rs @@ -119,9 +119,17 @@ pub enum NextControlFlowPosition { SameLine, /// Forces the next control flow to be on the next line.
