The author of the material, the translation of which we publish today, says that she is directly obsessed with writing clean code. She believes that the code should be written so that, firstly, with it, in the future, it would be convenient to work for other programmers, including its author, and secondly, taking into account the possibility of extending this code. That is, you need to strive to ensure that the application is relatively easy to add new features, and that its code base would be convenient to accompany. If the programs were written, taking into account only the needs of computers...

Despite the fact that module testing technologies have existed for 30 years (in 1989 Kent Beck wrote the article "Simple Smalltalk Testing: With Patterns"), nevertheless not all programmers own this technology and not all companies have made automatic testing part of their corporate culture . Even despite the obvious advantages of automatic testing, the behavioral resistance is still strong enough. Who tried to implement automatic tests, he knows that there is always some reason why this could not be done.

Because of the limitations on the ability to use the C ++ 11 compilers and the non-alternative to boost, there was a desire to write your own implementation of the standard C ++ 11 library on top of the C ++ 98 /C ++ 03 library supplied with the compiler.

News from the number of pleasantly unexpected ones it aroused all sorts of memories, sweet and not very much. And from her I got on this article is , and immediately felt sick of nostalgia, and wanted from the height of the past seven years to make a big dent in front of her like that.

Instead of the preface

 
Perhaps this picture should begin with any narration about boost , Loki , standalone, and also the implementations of the standard C ++ library that are supplied with compilers.
 
 
Yes, and if you thought that the developers of the standard library for the same g ++, clang, Visual Studio or, sorry Lord, C ++ Builder (former Borland, and the current Embarcadero) - gurus that do not crutches, do not break the standard for their compiler and do not write bicycles, then, most likely, you are not so actively using the standard C ++ library as it seemed to you.

You may remember the recent the announcement of a new static analyzer for Go under the name go-critic .
 
I checked with his help project golang /go and sent a few patches that fix some of the problems found there.
 
In this article we will look at the corrected code, and we will also be motivated to send even more similar changes to Go.

Sigma-type and you

 
Let's talk about a simple but powerful concept in programming - sigma-type .
 
 
The sigma type (a sum-type labeled join) can contain the values ​​of one and only one of several types. For example, consider the settings in INI -like configuration file. Let each setting be a string, an integer, or a Boolean value. If we wanted to make our library in C ++, we would write something like this:
 
std :: variant , and now we will get to know him better.
