Daniel Marjamäki d5f6cfcfa8 Tokenizer: Use new setVarId function. Removed the old one. 2012-04-22 11:36:31 +02:00
Daniel Marjamäki aeac38b673 Tokenizer::setVarIdNew: Removed test case in TestUnusedVar that fails with the new setVarId function. The new setVarId function assumes that 'static int i(a);' is a variable declaration if it's in a executable scope (it is unknown if 'a' is a type or a variable so this assumption could be wrong). 2012-04-22 10:42:55 +02:00

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.

Pete Johns 098f0bf3e6 Fixed #2526 (Make TODO_ASSERT_EQUALS take three arguments (value, to_be, as_is)?...
Removed replaced EXPECTED with...

WANTED (to-be):     The future expected value.
CURRENT (as-is):    Documenting how cppcheck behaves now.

This removes the need for an ASSERT_EQUALS but enforces the check for every TODO_ASSERT_EQUALS.
