* [clang-tidy] Update TransformerClangTidyCheck to use new Transformer bindings.Yitzhak Mandelbaum2019-11-061-3/+3
| | | | | | | | | | | | | | Summary: Updates the relevant source files to use bindings in `clang::transformer` rather than `clang::tooling`. Reviewers: gribozavr Subscribers: xazax.hun, cfe-commits Tags: #clang Differential Revision: https://reviews.llvm.org/D69804
* [libTooling] Move Transformer files to their own directory/library.Yitzhak Mandelbaum2019-10-101-1/+1
| | | | | | | | | | | | | | | | | | | Summary: The Transformer library has been growing inside of lib/Tooling/Refactoring. However, it's not really related to anything else in that directory. This revision moves all Transformer-related files into their own include & lib directories. A followup revision will (temporarily) add forwarding headers to help any users migrate their code to the new location.

* [clang-tidy] Extend TransformerClangTidyCheck to support adding includes.Yitzhak Mandelbaum2019-07-021-0/+5
| | | | | | | | | | | | | | | | | Summary: This revision implements support for the `AddedIncludes` field in RewriteRule cases; that is, it supports specifying the addition of include directives in files modified by the clang tidy check.

* [clang-tidy] Generalize TransformerClangTidyCheck to take a rule generator.Yitzhak Mandelbaum2019-06-261-7/+20
| | | | | | | | | | | | | | Summary: Tidy check behavior often depends on language and/or clang-tidy options. This revision allows a user of TranformerClangTidyCheck to pass rule _generator_ in place of a rule, where the generator takes both the language and clang-tidy options. Additionally, the generator returns an `Optional` to allow for the case where the check is deemed irrelevant/disable based on those options.

* [clang-tidy] In TransformerClangTidyCheck, require Explanation field.Yitzhak Mandelbaum2019-05-241-3/+7
| | | | | | | | | | | | | | | | | | | Summary: In general, the `Explanation` field is optional in `RewriteRule` cases. But, because the primary purpose of clang-tidy checks is to provide users with diagnostics, we assume that a missing explanation is a bug. This change adds an assertion that checks all cases for an explanation, and updates the code to rely on that assertion correspondingly.

* [clang-tidy] Add support for writing a check as a Transformer rewrite rule.Yitzhak Mandelbaum2019-05-221-0/+49
This revision introduces an adaptor from Transformer's rewrite rules (`clang::tooling::RewriteRule`) to `ClangTidyCheck`. For example, given a RewriteRule `MyCheckAsRewriteRule`, it lets one define a tidy check as follows: ``` class MyTidyCheck : public TransformerClangTidyCheck { public: MyTidyCheck(StringRef Name, ClangTidyContext *Context) : TransformerClangTidyCheck(MyCheckAsRewriteRule, Name, Context) {} }; ``` Reviewers: aaron.ballman Subscribers: mgorny, xazax.hun, cfe-commits, ilya-biryukov Tags: #clang Differential Revision: https://reviews.llvm.org/D61386 llvm-svn: 361418
