C++ IDE for Linux? [closed]
...ev: refactoring requires parsing the source code in some way. As far as I know, no VIM modules do that so the answer to your question is “none.” That's one of the reasons to prefer an IDE for IDE-centered languages such as Java. Since refactoring support (etc) for C++ is so minimal anyway (even ...

new Rhs("bar"))
std::shared_ptr<Lhs>
std::shared_ptr<Rhs>

Now, these are a few of the conditions whereby std::getline() terminates input:
If the stream has extracted the maximum amount of characters a std::basic_string<charT> can hold
If the end-of-file (EOF) character has be...
Process escape sequences in a string in Python
...Adding a regular expression to solve the problem
(Surprisingly, we do not now have two problems.)
What we need to do is only apply the unicode_escape decoder to things that we are certain to be ASCII text. In particular, we can make sure only to apply it to valid Python escape sequences, which are...
