查找并替换为正则表达式

Question

I'm trying to replace a bunch of function calls using regular expressions but can't seem to be getting it right. This is a simplified example of what I'm trying to do:

GetPetDog();
GetPetCat();
GetPetBird();

I want to change to:

GetPet<Animal_Dog>();
GetPet<Animal_Cat>();
GetPet<Animal_Bird>();

Answer 1

Use below regex:

(GetPet)([^(]*) with subsitution \1<Animal_\2>

Demo

Answer 2

You can use the following regex and code for that:

std::string ss ("GetPetDog();");
static const std::regex ee ("GetPet([^()]*)");
std::string result;
result = regex_replace(ss, ee, "GetPet<Animal_$1>");
std::cout << result << endl;

Regex :

• GetPet - Matches GetPet literally (we need no capturing group here)
• ([^()]*) - A capturing group to match any characters other than ( or ) 0 or more times ( * )

Output:
