Why the behavior is different from python binding?

[880019]

there is alternation pattern:

([
(jsx_text) @i18n_issue
(jsx_attribute
  (property_identifier) @attr_name
  (#match? @attr_name "^(alt|placeholder|aria-label|title)$")
  (string) @i18n_issue
)
])

It works in python binding, but (jsx_text) @i18n_issue is ignored in Java binding.

my Java code is:

try (var query = new Query(JsLanguage, source);
     var cursor = new QueryCursor(query)) {
   var items = cursor.findCaptures(tree.getRootNode()).toList();
   // dump each item in items
   // it proves "(jsx_text) @i18n_issue" never be used.
}

Could be because the library versions are different. Try the latest version of the CLI or Rust bindings.

Try the latest rust binding, it also supports alternation pattern like Python

---

Both Python and Java use the same version tree-sitter

• Python(0.25.2) -> Tree Sitter Core 0.25.10
• Java (0.25.6) -> Tree Sitter Core 0.25.10

---

Even I tried the latest Java binding with tree-sitter 0.26.3, the issue is the same.

The workaround is to convert alternation pattern to 2 independent patterns:

(jsx_text) @i18n_issue
(jsx_attribute
  (property_identifier) @attr_name
  (#match? @attr_name "^(alt|placeholder|aria-label|title)$")
  (string) @i18n_issue
)

Test data:
// app.jsx

import { useState } from 'react'
import reactLogo from './assets/react.svg'
import viteLogo from '/vite.svg'
import './App.css'

function App() {
  const [count, setCount] = useState(0)

  return (
    <>
      <div>
        <a href="https://vite.dev" target="_blank">
          <img src={viteLogo} className="logo" alt="Vite logo" />
        </a>
        <a href="https://react.dev" target="_blank">
          <img src={reactLogo} className="logo react" alt="React logo" />
        </a>
      </div>
      <h1>Vite + React</h1>
      <div className="card">
        <button onClick={() => setCount((count) => count + 1)}>
          count is {count}
        </button>
        <p>
          Edit <code>src/App.jsx</code> and save to test HMR
        </p>
      </div>
      <p className="read-the-docs">
        Click on the Vite and React logos to learn more
      </p>
    </>
  )
}

export default App
