JSDoc Parser breaks with a complex `@pattern` tag

[egandro]

TypeScript Version: 2.5.2

Code

  /**
   * @pattern ^[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\\.[a-zA-Z0-9-.]+$
   */
  public emailPattern: string;

Expected behavior:
expected '^[a-zA-Z0-9_.+-]+' to equal '^[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-.]+$'

Actual behavior:

This is parsed -^[a-zA-Z0-9_.+-]+
This is expected +^[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+.[a-zA-Z0-9-.]+$

Maybe I am doing something stupid or the parser is broken.

I guess the parser should wait for a line break before interpreting another @ char as a new jsDoc tag?

If you guys fix this. You might try the even more complex patten from here:

http://emailregex.com/

/^(([^<>()\[\]\\.,;:\s@"]+(\.[^<>()\[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/

We should special case parsing of pattern tags to parse text till end of line instead of till next tag.
