[bug] Literal strings are matched generically about ast-grep HOT 5 OPEN

This is fixed in tree-sitter/tree-sitter-rust#218

But it is blocked by https://github.com/tree-sitter/tree-sitter-typescript/blob/master/Cargo.toml#L29

More context: tree-sitter/tree-sitter-typescript#289

from ast-grep.

tree-sitter does not report string literal's content.

So both "foo" and "bar" has the same structure like

string_literal
  " opening quote
  " closing quote

from ast-grep.

You can use this workaround

rule:
  pattern: $E.with_meaning($D, $STR)
constraints:
  STR: { regex: '^"meaning"$'}
