Parameter type not assigned for parse in TypeScript.

[Symbolk]

I am trying to use this lib in TypeScript, with the following code:

import * as TreeSitter from 'tree-sitter';
import { Point, SyntaxNode, Tree } from 'tree-sitter';
const JavaScript = require('tree-sitter-javascript')
const treeSitter = new TreeSitter()
treeSitter.setLanguage(JavaScript)
    const sourceLines = [
      'let x = 1;',
      'console.log(x);'
    ];
    const tree = treeSitter.parse((index: any, position: Point) => {
      let line = sourceLines[position.row]
      if (line) {
        return line.slice(position.column)
      }
    })
    console.log(tree.rootNode.toString());

However, I am facing the following errors:

Argument of type '(index: any, position: Point) => string | undefined' is not assignable to parameter of type 'string | Input | InputReader'.
  Type '(index: any, position: Point) => string | undefined' is not assignable to type 'InputReader'.
    Type 'string | undefined' is not assignable to type 'string'.
      Type 'undefined' is not assignable to type 'string'.

I skimmed the issues and found this closed one relevant (#55), any ideas?

I suppose because you need to return "" the empty string in case of the end of the input.

Yeah, you are right!
Now I can compile and run it, but got another error:

'node_modules/tree-sitter/build/Release/tree_sitter_runtime_binding.node' was compiled against a different Node.js version using NODE_MODULE_VERSION 83. This version of Node.js requires NODE_MODULE_VERSION 87. Please try re-compiling or re-installing the module (for instance, using `npm rebuild` or `npm install`)..

I have tried node 14.16.1 and 14.0.0, they are corresponding to version 83 (https://nodejs.org/en/download/releases/), but it seems that there is NO version corresponding to version 87, so I am confused.

Looks like an issue with your environment and somehow customly compiled nodejs version. Could you provide more info:

• About your operation system / distro.
• Do you have a system node installation by some package manager?
• Where do you get other versions of node executables.
• A full command how you call your script with Node when you got the error.

1. System: macOS 10.15.6
2. Yes, I manage multiple node versions with NVM, the system version is 14.16.0
3. I install the versions with nvm install VERSION
4. I am developing a VSCode extension in typescript, and I'd like to integrate node-tree-sitter into it. When debugging the extension with F5 in VSCode, it reports this error.

You have to compile tree-sitter for the electron version of vs code, not your local node

@gpetrov @ahlinc Thanks for the hint! I am trying to rebuild it, but the following error is reported:

VSCode information:

Node version: 14.16.0

[gpetrov]

This is a common problem when rebuilding node 14+ modules on new macOS.

They need c++14 compiler.

So just edit binding.gyp and change:

'xcode_settings': {
        'CLANG_CXX_LANGUAGE_STANDARD': 'c++11',
      },

To

'xcode_settings': {
        'CLANG_CXX_LANGUAGE_STANDARD': 'c++14',
      },

Seems there is also a PR for this:

#83

Seems there is also a PR for this:

#83

Right, I also found several similar issues in other projects.

Now the problem is, since the pr is not merged yet but I am blocked by it, is there any way to rebuild a version and depend it on myself? I guess there should be a way but sorry I am new to node and ts.

[Symbolk]

I managed to solve this by manually editing node_modules/tree-sitter/binding.gyp and run ./node_modules/.bin/electron-rebuild to rebuild it to get the correct node_modules/tree-sitter/build/tree_sitter_runtime_binding.node.

Cheers!
