I'm curious, why does it perform better?
I'm putting words in Matthews mouth here, but things like move semantics
can reduce the need for allocations and copying, but like all such
"performance improvements" it needs to be used a zillion times before it
matters, and well, Geany does few things a zillion times (except inside
Scintilla's rendering code).
OK.
Readability is definitely better in C++11 when avoiding iterators and
using lambdas, but I was kind of hoping we could avoid those ugly cases. I
wasn't thinking of using the STL heavily, just a few containers like
string, and perhaps others for any specialized use cases.
Sadly, containers means iterators, inevitably, and yes C++03 syntax is
ugly, but you get used to it, and just type it automatically. Pity "auto"
and "for( a: container )" is C++11, oh well.
Yes. Unless we use a foreach macro ;-P
I'm not sure iterators are needed often for string though, but it's been
a while since I looked at code using it.
I proposed banning OOP, operator overloading and exceptions in src to make
it (much?) easier to understand & maintain the code vs idiomatic C++, with
all its unintuitive bug-prone corner cases (which are still in C++11), see
my reply to Lex for more info.
Looking at it again, I'm not sure we mean the same thing by OOP, its a much
abused and overloaded term, could you perhaps explain your meaning?
Depending on what you mean, banning it is either sensible, or the silliest
idea ever :)
I mean inheritance and virtual functions. I don't think they would pull
their weight in src, unless we were going to use gtkmm for custom widgets.
Yes, or maybe convert a core plugin that uses strings a lot, so we get the
benefit of RAII. I might look into it unless Colomban is against that (even
for a core plugin).
Good idea, plugins can be written in C++ now, without any changes to Geany
being needed. Just make sure you don't leak exceptions (unless you mean
to) since they currently mean terminate().
OK.

Nick
