[cfe-dev] Correct .clang-tidy syntax

[Alexander Kornienko]

Hi,

Thanks for reporting the problem. The example of configuration contained an
error: the braces are not needed in the indented YAML format, they only
make sense in the inline format. I've fixed the documentation page and help
message in r223235.

Also, you can always get an example of a valid configuration file
using clang-tidy
-dump-config:

$ clang-tidy -dump-config - --
---
Checks:          '-*,clang-diagnostic-*,llvm-*,misc-*'
HeaderFilterRegex: ''
AnalyzeTemporaryDtors: true
User:            alexfh
CheckOptions:
  - key:
google-readability-braces-around-statements.ShortStatementLines
    value:           '1'
  - key:             google-readability-function-size.StatementThreshold
    value:           '800'
  - key:
google-readability-namespace-comments.ShortNamespaceLines
    value:           '10'
  - key:
google-readability-namespace-comments.SpacesBeforeComments
    value:           '2'
  - key:             llvm-namespace-comment.ShortNamespaceLines
    value:           '1'
  - key:             llvm-namespace-comment.SpacesBeforeComments
    value:           '1'
...

Also, if you implement the storeOptions method in your check, you can see
how your check options are represented in configuration using:

$ clang-tidy -checks=-*,your-check-name -dump-config - --
