stderr at the end.

Alexander Kornienko 4f6b06673d [clang-tidy] Add support for custom configuration file names/formats.
Summary: We're using different clang-tidy frontends (command-line, batch analysis jobs, code review integration), some of which are limited in the choice of configuration format. In order to avoid duplication of configuration information, we need to support the same configuration format in the command-line tool. This patch adds an extension point to make this possible without rewriting FileOptionsProvider.

Alexander Kornienko 1efc425551 [clang-tidy] Default options in modules.
Summary:
This patch allows modules to specify default options for the checks
defined in them. This way a sufficiently configurable check can be registered in
multiple modules with different default options. E.g. the SpacesBeforeComments
option may be set to 1 for the "llvm-namespace-comments" check and to 2 for the
"google-readability-namespace-comment" check without modifying or extending the
check code.

This patch also registers the google-readability-braces-around-statements check
with suitable defaults.

Alexander Kornienko 35ddae4a9b [clang-tidy] Move some of the misc checks to readability/
Summary:
Some of the misc checks belong to readability/. I'm moving them there
without changing check names for now. As the next step, I want to register some
of these checks in the google and llvm modules with suitable settings (e.g.
BracesAroundStatementsCheck). I'm not sure if we want to create a "readability"
module, probably not.

Alexander Kornienko f305000a91 [clang-tidy] misc-braces-around-statements.ShortStatementLines option
Add option ShortStatementLines to trigger this check only if the statement spans
over at least a given number of lines.

Modifications from the original patch:
  merged test/clang-tidy/misc-braces-around-statements-always.cpp into
  test/clang-tidy/misc-braces-around-statements.cpp and removed unnecessary
  CHECK-NOTs from the tests.

2014-10-05 23:40:30 +00:00
Alexander Kornienko 8f7e7f73ea [clang-tidy] Add check misc-braces-around-statements.
This check looks for if statements and loops: for, range-for, while and
do-while, and verifies that the inside statements are inside braces '{}'.
If not, proposes to add braces around them.

Example:

  if (condition)
    action();

becomes

  if (condition) {
    action();
  }

This check ought to be used with the -format option, so that the braces be
well-formatted.

takes "default" options instead of "fallback" options, as it now uses these when
an option is not set in the configuration file (one exception is the checks

Benjamin Kramer ae8fc52237 [clang-tidy] Don't emit the same fixit multiple times.
If we had many header files we would attach the fix-it for all files to all

As this is very dependent on the code base it has some ways of configuration.
It's possible to pick between 3 modes of operation:

- Line counting: number of lines including whitespace and comments
- Statement counting: number of statements within compoundStmts.
- Branch counter

In addition a threshold can be picked, warnings are only emitted when it is met.
The thresholds can be configured via a .clang-tidy file.
