In hopes of not making this too much of a yak shave, I've gone with the immediately invoked lambda. ================ Comment at: clang-tidy/abseil/DurationRewriter.cpp:74 + Node, *Result.Context))) { + return tooling::fixit::getText(*MaybeCallArg, *Result.Context).str(); + } ---------------- lebedev.ri wrote: > hwright wrote: > > lebedev.ri wrote: > > > So you generate fix-it, and then immediately degrade it into a string. > > > Weird. > > This doesn't generate a fix-it, it just fetches the text of the given node > > as a `StringRef` but we're returning a `string`, so we need to convert. > > > > Is there a more canonical method I should use to fetch a node's text? > I don't know the answer, but have you tried looking what > `tooling::fixit::getText()` does internally? I have. It calls `internal::getText`, which, from the namespace, I'm hesitant to call in this context. ================ Comment at: clang-tidy/abseil/DurationRewriter.cpp:156 +llvm::Optional<DurationScale> getScaleForInverse(llvm::StringRef Name) { + static const llvm::DenseMap<llvm::StringRef, DurationScale> ScaleMap( + {{"ToDoubleHours", DurationScale::Hours}, ---------------- lebedev.ri wrote: > Are you very sure this shouldn't be [[ > https://llvm.org/docs/ProgrammersManual.html#llvm-adt-stringmap-h | > `StringMap` ]]? Nope. Thanks for the catch!
