Daniel Marjamäki b84547a312 Fixed #4798 (Token::Match(tok, '&|*|%var%') behaves differently when parsed or compiled) 2013-05-15 13:22:25 +02:00
PKEuS 3a35944c9e Changes in token.h/cpp:
- Properly set Token::_type to eVariable, eFunction or eName, depending on _function, _variable or _varId being set.
- Token can't be a variable and a function at a time - put Token::_function and Token::_variable into a union.

PKEuS f899e6ca30 Changed behaviour of %op% pattern accordingly to changes to Token::isOp(). Added %cop% as replacement for old %op% 2013-03-01 02:43:59 -08:00
PKEuS 670c4de8a9 Changed behaviour of Token::is*Op() functions:
- Rename Token::isOp() to Token::isConstOp() (indicating that the operator does _not_ modify the input variables)
- Create new Token::isOp(), returning true also for ++, -- and assignment operators
- Make Token::isExtendedOp() returning also true for all assignment and ++/-- operators

Andrew C. Martin bd0d9b9639 fix misspellings & gcc v3.4.6 warnings
1.  fix typos / misspellings
 - Fix misspelling within comments, variable/function names, stdout messages
 - changes the name of an error code: ```stlBoundries``` changed to ```stlBoundaries```.  Alias old name (```stlBoundries```) to the new one.

2.  fix gcc v3.4.6 32bit & 64bit warnings

 - fixes gcc v3.4.6 warnings, except for those in tinyxml and "-Wmissing-declarations" makefile warnings
 - in Preprocessor::handleIncludes(), replace a ```vector <bool>``` with ```stack<bool>``` (see ```vector<bool>``` warning below).
   - this is the only ```vector<bool>``` in the codebase
 - ```vector <bool>``` is actually a case of template specialization, and is not recommended, according to the following links:

 - in the codebase before and after this change, testrunner SEGVs in a number of places on gcc v3.4.6, including ```Check::~Check()```, among others
   - fc42fc95 fixes this particular runtime issue for DJGPP & __sun

Andrew C. Martin 4a73c93750 Fix compiler warnings and comment/string typos
- fix g++ warning:

> lib/checkother.cpp:3779: warning: comparison between signed and unsigned integer expressions

 - fix suncc warning (see [everything2](http://everything2.com/title/C%252B%252B%253A+static+extern+%2522C%2522)):

> "lib/checkmemoryleak.cpp", line 578: Warning (Anachronism): Formal argument __compar of type extern "C" int(*)(const void*,const void*) in call to bsearch(const void*, const void*, unsigned long, unsigned long, extern "C" int(*)(const void*,const void*)) is being passed int(*)(const void*,const void*).

- prefer empty() / isEmpty() over "size() > 0" (cases not caught by stlSize)

- fix word misspellings (mostly comments, a few output lines)

  - Parenthesis => Parentheses (both variations were used in the codebase)

  - fix typo and wording ("never alwayw") in gui/test/data/benchmark/simple.cpp's CheckOther::unsignedPositive():

```
-  "An unsigned variable will never alwayw be positive so it is either pointless or "
+  "An unsigned variable can't be negative so it is either pointless or "
```

Edoardo Prezioso 6236e1dc38 Token::Match: removed harmless special code for initial '!!foo' patterns. 2013-01-09 20:13:33 +01:00
Thomas Jarosch 7dd07d8e77 Properly implement %op% for Token::multiCompare
Use tok->isOp() instead of doing it "manually".

This fixes false positives for the C++ template case since
the brackets in "template < something >" are not comparison operators.

Profiling showed using tok->isOp() is actually faster than before (-O2).
2013-01-09 17:05:53 +01:00
Edoardo Prezioso 1affb0c96b Use more Effective C++ code style in Token class:
1)The non-const version of Token::tokAt and Token::linkAt now will use a combination of const_cast and static_cast to remove duplicate code.
2)The non-const versions of Token::find(simple)match are added, in order to avoid the usage of const_cast outside the Token code.
3)As a consequence of 2), an useless const_cast applied to a call of Token::findsimplematch in Tokenizer code is removed.

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 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

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.
- Previously MathLib errors did not provide a filename, but after this change at least source file name should be printed

- Change also Token to use InternalError
- Modify Cppcheck-class to catch InternalError instead of Token
- Run dmake to update Makefile
