Edoardo Prezioso aeb4531a58 Token::Match: add a new pattern: '%comp%'.
Token::Match returns true if the token is a comparison operator. It's equivalent to matching '<|<=|==|!=|>=|>' and the tests show that the new pattern speeds up the program execution. Added the new pattern in CheckInternal (and also reordered the %cmd% lists) and in TestToken.

Edoardo Prezioso 9dae536ce3 Little tweaks to Token::Match code. 2012-11-25 15:20:50 +01:00
Edoardo Prezioso e0c10efdce Add a 'prepend' bool option to Token::InsertToken.
If it's true, add a new token before this. Except when this is the first one in the list, because there's not a way to update the list.front (I noticed some Token functions can potentially delete the list.front(), I don't know which effects does it cause).

PKEuS 4ea2df8671 Changed handling of type wchar_t:
- Don't simplify wchar_t to unsigned short on Win32 platforms to ensure that checking of strings and nullpointer dereferences works.
- Added it as standard type

Edoardo Prezioso 87c931b74b Add '%char%' as pattern to match in Token::Match.

PKEuS e0a3ca0845 Refactorizations in class Token: changed handling of different types of tokens.
- Replace _isNumber, _isName, _isBoolean attributes by a single _type attribute (enum Token::Type), because not two of the old booleans could be true at the same time.
-> Add support for lots of different other kinds of tokens. (More precise checking of token type possible)
-> Replaced instant checking of type for Operators, etc. by a value calculated at creation time. (Faster checking)

PKEuS cb064dc20e Implemented generic mechanism for '<'-'>' "linkage" before link() works (Taken from Scope::findClosingBracket, but C++11 right angle bracket support added): Token::findClosingBracket

Fixed build failure in checkclass.cpp

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
2012-04-16 19:51:07 +02:00
PKEuS 8cb904feaa Refactorizations in class Token:
- Added support for < and > in nextArgument()
- Made isStandardType inline by writing its implementation to token.h (like other bool is*() functions)
- Made firstWordEquals return bool instead of integer (only 0 and 1 were returned)
- Use std::string::empty() instead of operator==(""); Use character literals instead of string literals for single characters printed.

Reijo Tomperi 194327048a Add InternalError and change MathLib to throw it in case of an error.

and if token is provided, also line number should be printed.
- Change also Token to use InternalError
- Modify Cppcheck-class to catch InternalError instead of Token
- Run dmake to update Makefile

Thomas Jarosch 19c9c97608 Fix single %op% operator not working at all
When parsing the Token::Match pattern, we accesed

In addition the unit test function for %op%
wasn't registered in the test suite. Ups.

All fixed now and also provide a complete
check for all operators %op% supports.

Pete Johns c6acdccfa0 Fixed #1132 (Detection of misused scope objects)
Emits error in the form:

    [useless_lock.cpp:18]: (error) instance of "Lock" object destroyed immediately

...if an instance of a class or struct is unnamed and therefore destroyed
straight after creation.

Removed "internal error" from token.cpp, since in this case varid would be NULL.
