PKEuS 88aa08e71b Refactorizations in test suite:
- Removed redundant tokenization helper functions in testtokenize.cpp and testsimplifytokens.cpp
- Pass arguments as const char[] or const std::string& to avoid instanciation or at least copying of strings
- Removed redundant calls to Tokenizer::validate() - This function is already called implicitly by tokenize() and simplifyTokenList()
2012-04-17 09:51:08 +02:00
PKEuS bac8ed7127 Refactorized stringification of tokens:
- Function that stringifies one token: Token::stringify()
- Functions that stringify a list of tokens: Token::stringifyList()
-- Single and powerful "base" function, used by several "light" functions
Refactorized
- testtokenize.cpp and testsimplifytokens.cpp: Use improved stringification functions instead of several local implementations
- Avoided redundand creation of std::string when using TestTokenizer::tokenizeAndStringify and in cmdlineparser.cpp

Edoardo Prezioso 27801b35eb Other improvements to tokenizer code.
Handle SQL code better, even when there's no ';' after 'EXEC SQL'.
simplifyVarDecl: Check with 'Token::Match' once when you have to check a pattern inside which there should be a number or a variable. Use '%any%' and after that check if that string is a number or a variable name later.
simplifyGoto: process also anonymous structs and unions which should have 'indentspecial' incremented, skip code like 'var = { ... }'.

Edoardo Prezioso 5f522fb841 Tokenizer: improve code and remove redundant checks.

Edoardo Prezioso 6e2f2816de Improve same expression check: remove '%op%' pattern and add ',' for the same expressions as an argument inside a function.
Improve compound assignment simplification: use already defined 'isAssignmentOp' and extend the adding parenthesis to a generic operator, not only to the arithmetical ones. See: http://en.cppreference.com/w/cpp/language/operator_precedence

Kimmo Varis cfcfa3f000 Use "enabled" list for the style checking.
Settings-class currently enables style checking via dedicated
boolean attribute. All other CLI's enable-options are handled
through the enable-list. This commit moves style-check enabling
to use the enable-list.

Main advantage is the consistency how options are handled/stored
in the Settings class. Which also unifies using them for the other
code. You need to enable certain type of checks? Use the
addEnabled()-method. You want to check if certain type of checks
are enabled? Use the isEnabled()-method.
