C++11 usage status
The table lists C++11 features and whether they can be used in Inkscape or not (yet). Add C++11 features that you would like to use to the table, so that we know what to test for to increase the C++11 "allowance".
| Feature | Can use? | Comment |
|---|---|---|
| std::unique_ptr<> | not yet | replaces boost::scoped_ptr<> and std::auto_ptr<> |
| std::shared_ptr<> | not yet | replaces boost::shared_ptr<> |
| std::unordered_*<> | replaces the hack in util/unordered-containers.h | |
| auto (type inference) | not yet | |
| enum class | not yet | |
| range-based for | not yet | |
| lambda functions | not yet | in-place defitions for small functions |
| constructor delegation | not yet | reduces boilerplate when an object has many constructors |
| right angle brackets in templates | not yet | fixes coding style oddity |
| async, futures | not yet | allows easy multithreading |
| toxic feature of doom | NO | Never use this (in case we stumble upon C++11 features that we really don't like) |
| supported feature | from 0.50 |
C++11 platform status
Also see this page http://wiki.apache.org/stdcxx/C%2B%2B0xCompilerSupport
Note that "__cplusplus" is always "1" for GCC 4.6 that is used on Windows. So "#if __cplusplus < 201103L" or variants does not work to choose between C++03 or C++11 code.
The table lists C++11 features and whether they work in trunk on a certain platform as advertised. If all lights are green -> set the light to green in the [C++11 usage status] section (taking current trunk version into account).
