Visual Studio 正则表达式模式不起作用：^.*Foo[^.,]\(+.*$

Question

I have following lines of code,

int Foo(char);

int Foo()
{
//do something
}

int FooBar(char, char);
foo.Get();
fooBar.Get();
m_FooBar.Get();
case foo:
fooBar(x,y);

I want to search only for function reference, declaration and definition with 'Foo' name. Only four of the above lines to be shown in result

1. int Foo(char);
2. int Foo()
3. int FooBar(char, char);
4. fooBar(x,y);

I tried

^.*Foo[^.,]\(+.*$

But it also selected case Foo:

Whats wrong with this regex?

Answer 1

You may use

^.*Foo\w*\(+.*$

Make sure you make it case insensitive, as shown in this regex demo . The [^.,] part is a negated character class, and it matches any char that is not a dot and comma, it might match a line break char. With \w , you only match [A-Za-z0-9_] characters.

Details

• ^ - start of string (line in text editors)
• .* - any 0+ chars other than line break chars, as many as possible
• Foo - a Foo word
• \w* - 0 or more letters, digits, _ s
• \(+ - 1 or more ( chars
• .* - any 0+ chars other than line break chars, as many as possible
• $ - end of string (line in text editors).
