[Review] Type Traits Extension ending tomorrow
Dear All, The fast track review of Frédéric Bron's extensions to the Type Traits Library is ending tomorrow. If you plan to submit a review, please do so as soon as possible. Thanks in advance to all participants of the review. =========== What is it? =========== This extension adds 37 new traits corresponding to the following 37 operators: - binary: ==, !=,<,<=,>,>=, , +, -, *, /, %, +=, -=, *=, /=, %=, , &&, ||, ,&, |, ^,<<,>>,&=, |=, ^=,<<=,>>= - prefix: ++, --, +, -, !, ~, * - postfix: ++, -- Each trait can detect if the operator can be used with particular types and if needed, if the return type is convertible to some type. =================== Getting the library =================== The latest version can be downloaded by different ways: - from the vault with unix line ending: http://www.boostpro.com/vault/index.php?action=downloadfile&filename=type_traits.tar.bz2&directory=Extension& - from the vault with dos line ending: http://www.boostpro.com/vault/index.php?action=downloadfile&filename=type_traits-dos.tar.bz2&directory=Extension& - from the sandbox:http://svn.boost.org/svn/boost/sandbox/type_traits/ The entry point of the documentation is type_traits/libs/type_traits/doc/html/boost_typetraits/category/value_traits/operators.html The library has been tested with: - MSVC 8, 9, 10 on Windows, - g++ 4.4.5 on Linux, - intel 10.0 and 11.1 on Linux. To test the library, the simplest is to untar the headers in your boost include directory. For this, you can download the header part of the extension: - from the vault with unix line ending: http://www.boostpro.com/vault/index.php?action=downloadfile&filename=type_traits.headers_only.tar.bz2&directory=Extension& - from the vault with dos line ending: http://www.boostpro.com/vault/index.php?action=downloadfile&filename=type_traits.headers_only-dos.tar.bz2&directory=Extension&
A short review. I used the library on Mac OS X in both clang and g++. The code appears to work fine after one small bug/confusion was fixed. The library is generally complete and functions well. My one request would be for an example or two! I wrote (for my own uses) a "maybe_print" function, which prints a value if the appropriate operator<< ostream overload exists, else prints "<NOT PRINTABLE>". I think a small example like this would show a practical use of the library, and how to make use of enable_if, or some other overload method. I believe the library should be accepted.

=========== What is it? ===========
This extension adds 37 new traits corresponding to the following 37 operators: - binary: ==, !=,<,<=,>,>=, , +, -, *, /, %, +=, -=, *=, /=, %=, , &&, ||, ,&, |, ^,<<,>>,&=, |=, ^=,<<=,>>= - prefix: ++, --, +, -, !, ~, * - postfix: ++, --
Each trait can detect if the operator can be used with particular types and if needed, if the return type is convertible to some type.
=================== Getting the library ===================
The latest version can be downloaded by different ways: - from the vault with unix line ending: http://www.boostpro.com/vault/index.php?action=downloadfile&filename=type_traits.tar.bz2&directory=Extension& - from the vault with dos line ending: http://www.boostpro.com/vault/index.php?action=downloadfile&filename=type_traits-dos.tar.bz2&directory=Extension& - from the sandbox:http://svn.boost.org/svn/boost/sandbox/type_traits/
The entry point of the documentation is type_traits/libs/type_traits/doc/html/boost_typetraits/category/value_traits/operators.html
The library has been tested with: - MSVC 8, 9, 10 on Windows, - g++ 4.4.5 on Linux, - intel 10.0 and 11.1 on Linux.

Hmm! That one capability perks my interest more than the whole rest of the Type Traits Extension library. I had trouble imagining how I might use the operator traits. Whether or not your example makes it into the library documentation, would you please share maybe_print()?
