[PATCH] D46000: [AST] Added a helper to extract a user-friendly text of a comment.

[Eric Liu via Phabricator via cfe-commits]

ioeric added a comment.

Thanks for adding the tests!



================
Comment at: include/clang/AST/RawCommentList.h:138
+  /// the overload with ASTContext in the rest of the code.
+  std::string getFormattedText(const SourceManager &SourceMgr,
+                               DiagnosticsEngine &Diags) const;
----------------
I think we can get rid of the interface that takes `ASTContext`? If `SourceManager` and `Diags` are sufficient, I don't see why we would want another interface for ASTContext.


================
Comment at: lib/AST/RawCommentList.cpp:352
+  // comments::Lexer. Therefore, we just use default-constructed options.
+  CommentOptions DefOpts;
+  comments::CommandTraits EmptyTraits(Allocator, DefOpts);
----------------
I'm not quite sure about this. Could we just require a `CommandTraits` in the interface? And only make this assumption in tests?


================
Comment at: unittests/AST/CommentTextTest.cpp:32
+  std::string formatComment(llvm::StringRef CommentText) {
+    llvm::IntrusiveRefCntPtr<vfs::InMemoryFileSystem> EmptyFS(
+        new vfs::InMemoryFileSystem);
----------------
`SourceManagerForFile` added in D46176 should save you a few lines here. (I'm landing it right now...)
