Detailed Description

Checks that bodies of if statements and loops (for, range-for, do-while, and while) are inside braces.

Before:

if (condition)
statement;

After:

if (condition) {
statement;
}

Additionally, one can define an option ShortStatementLines defining the minimal number of lines that the statement should have in order to trigger this check.

The number of lines is counted from the end of condition or initial keyword (do/else) until the last line of the inner statement. Default value 0 means that braces will be added to all statements (not having them already).

Member Function Documentation

◆ check()

void clang::tidy::readability::BracesAroundStatementsCheck::check ( const ast_matchers::MatchFinder::MatchResult &  Result)
overridevirtual

ClangTidyChecks that register ASTMatchers should do the actual work in here.

Reimplemented from clang::tidy::ClangTidyCheck.

Definition at line 115 of file BracesAroundStatementsCheck.cpp.

◆ onEndOfTranslationUnit()

void clang::tidy::readability::BracesAroundStatementsCheck::onEndOfTranslationUnit ( )
override

Definition at line 264 of file BracesAroundStatementsCheck.cpp.

◆ registerMatchers()

void clang::tidy::readability::BracesAroundStatementsCheck::registerMatchers ( ast_matchers::MatchFinder *  Finder)
overridevirtual

Override this to register AST matchers with Finder.

This should be used by clang-tidy checks that analyze code properties that dependent on AST knowledge.

You can register as many matchers as necessary with Finder. Usually, "this" will be used as callback, but you can also specify other callback classes. Thereby, different matchers can trigger different callbacks.

This will only be executed if the function isLanguageVersionSupported returns true.

If you need to merge information between the different matchers, you can store these as members of the derived class. However, note that all matches occur in the order of the AST traversal.

Reimplemented from clang::tidy::ClangTidyCheck.

Definition at line 107 of file BracesAroundStatementsCheck.cpp.

◆ storeOptions()

void clang::tidy::readability::BracesAroundStatementsCheck::storeOptions ( ClangTidyOptions::OptionMap Options)
overridevirtual

Should store all options supported by this check with their current values or default values for options that haven't been overridden.

The check should use Options.store() to store each option it supports whether it has the default value or it has been overridden.

Reimplemented from clang::tidy::ClangTidyCheck.
