Transferred from bug tracker

be easier to handle discussion.

Original bug (list)

This report is a grab bag of some C++11 things that need fixing so they
don't get lost, alpha numbered to refer to as they are fixed. The list is
not intended to be exhaustive as I don't use C++11 in anger yet. There are
some non-C++11 specific ones I identified as well, some of these are
already known but not well bug reported.

a. R raw string syntax doesn't highlight
b. raw strings containing a " break symbol parsing
c. user defined "numeric" literals show as numbers, since they may not be
numbers should show as some other highlight
d. user defined "string" literals show as strings and the suffix is not
highlighted
e. operator delete[] does not highlight the []
f. forward declared classes not always highlighted as types, seems to need
the {}
g. declarations class::nested var; insert var into class in symbols
h. scope autocompletion on -> should remain after ->*
i. [[ ]] attribute syntax not parsed, confuses the parser
j. typed enums (eg enum class xxx {};) parsed as classes and erroneously
k. enums with base types fixed don't appear in symbols
l. namespace aliases parsed as "Other" not namespaces
m. declarations namespace::type var; insert var into the namespace on
symbols
n. deleted member functions not identified in symbols, show as if declared
to exist, not to be removed (picky)
o. direct initialisations do not show as symbols
p. scope autocomplete does not show base class members
q. scope autocomplete does not respect access controls on members
r. friend declarations are treated as member declarations
s. template class parameters not recognised as typenames
t. tooltips don't work for template parameters when < is typed
u. explicit specialisations break autocompletely
v. the documented limitation of not parsing local declarations should be
mentioned for completeness

Linux Geany 1.23 (git >= eeddd6f), en_AU.UTF-8 : GTK 2.24.10, GLib 2.32.3

Most of the items in the attachment were tested to compile (possibly with
extra surrounding code) on GCC 4.7.1 (errors in transcription excepted :)

Colomban replies:

a: fixed, it was "just" a missing mapping for SCE_C_STRINGRAW (how this
happened I don't know…)

c: ok, complete parsing of numbers may help, but it probably would just not
highlight the non-numeric suffix (as the string suffixes, your "d" point).
Though, note that the current highlighting of numeric constant is perfectly
exact from the C preprocessor point of view (last point of
http://gcc.gnu.org/onlinedocs/gcc/Incompatibilities.html). BTW, I have a
patch for "proper" number parsing I did for the Vala number methods bug.

d: this is not really fixable, how would you differentiate a
"string"MACRO_OR_DEFINE from those C++11 user literals?

f: ok, quite easy to fix, but having declarations (so without the
definition) in the type list may confuse the scope completion code (since
the declaration is a perfect match, simply with no children).


j and k: fixed in Git


n: I don't understand this one.

v: nor do I get this one.

Cheers
