Are you clear with unsigned?

The “unsigned” Conundrum

by Tony “Bulldozer00” DaSilva

From the article:

A few weeks ago, CppCon16 conference organizer Jon Kalb gave a great little lightning talk titled “unsigned: A Guideline For Better Code“. Right up front, he asked the audience what they thought this code would print out to the standard console:

Even though -1 is obviously less 1, the program prints out “a is not less than b“. WTF?

Following the core guidelines is becoming easier.

C++ Core Check code analysis is included with VS “15”

by Andrew Pardoe

From the article:

Visual Studio “15” Preview 5 now includes the C++ Core Guidelines Checkers. This means you no longer have to install the C++ Core Check package from NuGet to check your code against rules and profiles in the C++ Core Guidelines. Just configure Code Analysis to include the C++ Core Check extensions.

camomilla: C++ error simplification script - - Vittorio Romeo

By Vittorio Romeo | Oct 12, 2016 02:29 AM | Tags: None

Article covering "camomilla", a Python script designed to post-process heavily-template-based C++ errors in order to make them easier to read.

camomilla: C++ error simplification script

by Vittorio Romeo

From the article:

camomilla uses simple text transformations to make gcc and clang errors smaller and easier to read. [...] The main text transformation used by camomilla to prevent full expansion of templates is "template typename collapsing", which hides nested typenames up to a user-specified depth. [...] The two other current transformations offered by camomilla are simple regex replacements that can act on namespaces or generic symbols. They can be defined in .json configuration files (which can recursively include each other!) [...] camomilla helps with [continuously transforming the same error] by automatically caching the last processed original error, so that the user can play around with different transformations and options.
