Description Alfred Krohmer CLA 2010-10-07 08:48:24 EDT 
Build Identifier: 20100917-0705

When using some new C++0x language features, Eclipse underlines (with orange) the code in the editor, because it doesn't know the new syntax.

Examples:
- iterating over a container:
  vector<int> v = { 2, 1, 4 }; // not the matter, recognized
  for (int &i : v)
      cout << i << endl;
- lambda expressions: (assuming the same vector as above)
  std::for_each (v.begin(), v.end (), [] (int &i) { cout << i << endl; });

It would be nice to see these features recoginzed by Eclipse so that the code won't get unreadable by warning underlinings.

Reproducible: Always

I think this is already in CDT 8.0, see bug 316307. If you want to try it, you can download a build here:
http://download.eclipse.org/tools/cdt/builds/8.0.0/index.html
Comment 2 Alfred Krohmer CLA 2010-10-07 13:08:01 EDT 
I just installed the most recent build from http://download.eclipse.org/tools/cdt/builds/8.0.0/I.I201009242334/index.html and Eclipse now recognizes the lambda expressions, but still complains about the range-based for loop.
Comment 3 Doug Schaefer CLA 2010-10-07 13:59:45 EDT 
Wrong Component. C++0x is still a work in progress. I believe Markus has bugs open for this already. We're almost there.
Comment 4 Markus Schorn CLA 2010-10-08 02:35:52 EDT 
I have not yet created bugs for all of the c++0x features, lambda expressions are covered by bug 316307.
I will use this bug for 'Range based for', the specification is here:
