Parse error

Getting this error on latest rjsx

Error running timer ‘js2-mode-idle-reparse’: (wrong-type-argument js2-node [cl-struct-rjsx-identifier 60 1573 3 nil nil nil #s(js2-name-node 39 1573 3 nil nil "div" nil)])

What are your emacs version, rjsx version, js2-version, file contents?

[fxfactorial]

What are quick ways to find rjsx version? I don't know if I can share file content, depends what part of file it is.

[felipeochoa]

M-x package-list-package and look for rjsx.

Without the entire file contents I probably won't be able to debug. I'd suggest trying to reproduce with a smaller file first

REMOVED CAUSE PROP CODE

Can you tell me when you have copy pasted it so I can delete from here.

[felipeochoa]

rjsx does not support flow types. If you take those out does it solve the problem?

[fxfactorial]

its fine with other flow files, removing flow still causes same error

[felipeochoa]

What's your emacs version and js2 version?

[fxfactorial]

emacs: emacs: 26.1-2 via brew cask install emacs js2: 20180627.744

[felipeochoa]

Ok. I don't have 26 handy to debug. Can you (after deleting the flow types) enable debug on error and post the backtrace?

I'm seeing the same problem:

emacs version 26.1 rjsx version 20180314.845 js2 version 20180331.2247

Possibly related to this issue over at js2?

File contents on which I'm seeing this problem:

import React from 'react'
import ReactDOM from 'react-dom'

class App extends React.Component {
  render () {
    <div className='app' />
  }
}

ReactDOM.render(<App />, document.getElementById('root'))

if (module.hot) {
  module.hot.accept()
}

Seems like @fxfactorial has some problems with the privacy of the code they've posted. Since we can reproduce with mine above, I'd say he can delete his.

I'll be updating and checking for the same traceback here as soon as I post this.

EDITED TO NOTE that this also happens on a pre-release version of emacs 27, though I'm not sure how old that build really is.

[bbenne10]

Oh. Interesting. I have updated both rjsx and js2, but it looks like the problem might be solved?

@fxfactorial: try to recompile the extensions. I forced this by simply deleting my ~/.emacs.d/elpa/{rjsx-*,js2-*}, which caused use-package to download the newer versions and build new byte-code.

[fxfactorial]

@bbenne10 yep, that solved it!

[torgeir]

That fixed it on my end as well!
