From 0446501493d9f07f4e0a3deb25722481b55c5dd7 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Thu, 26 Feb 2026 09:02:12 +0000 Subject: [PATCH 1/8] Update directive syntax from //:funit: to #warning funit - Modified `directives/FUnitSourceGenerator.cs` to parse `SyntaxKind.WarningDirectiveTrivia`. - Implemented robust parsing for `#warning funit` with optional whitespace and case-insensitivity. - Updated `directives/SR.cs` with new `DirectivePrefix` and `DirectiveSeparators` (added tab). - Updated `test/Directives_test.cs`, `sandbox/Sandbox.cs`, and `README.md` to reflect the new syntax. - Updated `test/Directives_test.cs` to use the local `FUnit.Directives` project for testing. - Ensured trailing whitespaces and unrelated comments are preserved. - Verified changes by building the `sandbox` project and observing the source generator in action. --- README.md | 4 ++-- directives/FUnitSourceGenerator.cs | 31 ++++++++++++++++++++---------- directives/SR.cs | 4 ++-- sandbox/Sandbox.cs | 30 ++++++++++++++--------------- test/Directives_test.cs | 12 ++++++------ 5 files changed, 46 insertions(+), 35 deletions(-) diff --git a/README.md b/README.md index 9b4928e..bdf648c 100644 --- a/README.md +++ b/README.md @@ -149,13 +149,13 @@ Must.BeTrue(!list.Contains(x)); // ✅ Prefer: Must.HaveSameSequence(expectedLi ## 🧭 `FUnit.Directives` -With FUnit.Directives package, you can *include* external file into file-based app project by adding special directive comment `//:funit:include `. +With FUnit.Directives package, you can *include* external file into file-based app project by adding special directive `#warning funit include `. ```cs #:package FUnit@* #:package FUnit.Directives@* -//:funit:include ./path/to/external-file.cs +#warning funit include ./path/to/external-file.cs return FUnit.Run( /* tests depending on 'external-file.cs */ ); ``` diff --git a/directives/FUnitSourceGenerator.cs b/directives/FUnitSourceGenerator.cs index 322b9a0..1c18311 100644 --- a/directives/FUnitSourceGenerator.cs +++ b/directives/FUnitSourceGenerator.cs @@ -57,12 +57,12 @@ public void Execute(GeneratorExecutionContext context) foreach (var syntaxTree in context.Compilation.SyntaxTrees) { var root = syntaxTree.GetCompilationUnitRoot(); - var comments = root + var directives = root .DescendantTrivia() - .Where(t => t.IsKind(SyntaxKind.SingleLineCommentTrivia)) + .Where(t => t.IsKind(SyntaxKind.WarningDirectiveTrivia)) .ToList(); // ToList is better than ToImmutableList in this case - foreach (var trivia in comments) + foreach (var trivia in directives) { if (trivia.SyntaxTree is null) { @@ -72,26 +72,37 @@ public void Execute(GeneratorExecutionContext context) continue; } - if (!trivia.ToString().StartsWith(SR.DirectivePrefix, StringComparison.Ordinal)) + // Check for no indentation + var line = trivia.GetLocation().GetLineSpan().StartLinePosition.Character; + if (line != 0) { continue; } - // Check for no indentation - var line = trivia.GetLocation().GetLineSpan().StartLinePosition.Character; - if (line != 0) + var fullText = trivia.ToString(); + if (!fullText.StartsWith("#", StringComparison.Ordinal)) { continue; } - var fullText = trivia.ToString().TrimEnd(); + var textAfterHash = fullText.Substring(1).TrimStart(); + if (!textAfterHash.StartsWith("warning", StringComparison.OrdinalIgnoreCase)) + { + continue; + } + + var textAfterWarning = textAfterHash.Substring(7).TrimStart(); + if (!textAfterWarning.StartsWith(SR.DirectivePrefix, StringComparison.OrdinalIgnoreCase)) + { + continue; + } #if DEBUG context.ReportDiagnostic( - Diagnostic.Create(SR.DebugDiagnostic, trivia.GetLocation(), fullText)); + Diagnostic.Create(SR.DebugDiagnostic, trivia.GetLocation(), fullText.TrimEnd())); #endif - var keywordAndArgs = fullText.Substring(SR.DirectivePrefix.Length); + var keywordAndArgs = textAfterWarning.Substring(SR.DirectivePrefix.Length); var parts = keywordAndArgs.Split(SR.DirectiveSeparators, 2, StringSplitOptions.RemoveEmptyEntries); var keyword = parts.FirstOrDefault()?.Trim() ??
