tree-sitter | An incremental parsing system for programming tools | Parser library

I'm trying to run an existing project but I keep getting this error: error logs image

when I try to run "npm i", can someone please explain what this error is about or guide me through the steps to solve it?

TIA

in case you can't see the logs:

I'm trying to create a tree-sitter for a Minecraft function grammar.

The structure of the language looks like this:

I'm trying to install dbt tool to Window 10. There is Python 3.9 and also VS2019 installed.(I don't know why required)

I'm getting strange errors and wondering errors and what should be done:

Command:

I'm working on trying to create and use tree-sitter grammar in a language server I am implementing in order to support features like finding all references of a variable. Given the grammar I would be able to write a query to find all of the references to a variable with a specific name (ex. myVar). However, the language I am writing a language server for uses case insensitive variables (ex. myVar can be referenced as MYVAR, MyVaR, myvar, etc.).

How would I be able to write a tree-sitter query to match a pattern where a token must case-insensitively match a particular string?

I could write the query to not filter by the variable name and implement my own filtering of the results, but I was wondering if there was a way to handle this within the query itself rather than implementing custom filtering code.

Here is a simplified example case to show what I mean.

Given the following grammar, I want to query for all of the set_statements that set a new value to the variable myVar.

This might be related to me not understanding the Keyword Extraction feature, which from the docs seems to be about avoiding an issue where no space exists between a keyword and the following expression. But say I have a fairly standard identifier regex for variable names, function names, etc.:

/\w*[A-Za-z]\w*/

How do I keep this from matching a reserved keyword like IF or ELSE or something like that? So this expression would produce an error:

int IF = 5;

while this would not:

int x = 5;

Consider an infix operator like subset (⊂). The subset operator is not associative, because its result (a boolean) is not itself a set and so cannot be fed into one or another side of the subset operator. Consider:

I have created a tree-sitter parser that is parsing some legacy SAP language we use in order to make a package compatible for ATOM. I will be very literate in my actions taken, as I am not very confident where I messed up.

According to the tree-sitter documentation many guides I read - I've done the following:

Added D:\path-to-project\node_modules.bin to PATH

If I have a simple grammar in tree-sitter:

From looking at pull requests & issues I see there are typescript definitions (possibly currently out of date) in the node-tree-sitter module; how do I access these definitions from typescript, and what would be the equivalent of the following node-tree-sitter sample javascript code in typescript?
