Question

In a language built on top of Java (so I cannot use regular parsers) I want to parse several sourc code files an extract the following information:

• name and extends/implements part of public (inner) classes
• public method declarations

So for a given file

public class A extends B {

  private int foo
  public int getFoo() {
    ...
  }

  private class Inner1 {

  }

  public class Inner2 {

  }
}

I would like to get with a single or several Regexps:

public class A extends B
public int getFoo()
public class Inner2

Answer 1

Let me know if this isn’t quite complex enough, but it will basically look for “public” followed by a space, then anything that isn’t an opening curly brace:

public\s[^{]+

Output is below:
